Sample records for rheumatic mitral stenosis


    Suryani Malik


    Full Text Available Rheumatic heart disease (RHD is the permanent heart valve damage resulting from one or more attacks of acute rheumatic fever (ARF, representing the permanent lesions of the cardiac valve. Rheumatic heart disease’s patient with valvar involvement usually require long term follow-up. The ultimate decision of clinical management or invasive therapy is made on an individual basis. We reported a 11-year-old girl with RHD and severe mitral stenosis whom underwent   mitral valve replacement with mechanical valve. Postoperative echocardiogram showed no mitral regurgitation and we gave anticoagulant to maintain INR of 3-4 by giving warfarin 2mg / kg each day for lifelong to prevent bleeding and thrombosis.

    We sought to explore the pulmonary haemodynamic changes in rheumatic mitral stenosis patients with secondary pulmonary hypertension. The pulmonary artery resistance and compliance of 35 patients with rheumatic mitral stenosis and 12 controls without cardiopulmonary vascular disease were evaluated by using an improved method, which is based on making calculations with parameters obtained from right heart catheterisation. The results are as follows: (1) pulmonary artery compliance in patients with secondary pulmonary hypertension was significantly lower than that of the control group (P0.05) The walls of pulmonary artery vessels in patients with pulmonary hypertension secondary to rheumatic mitral stenosis appeared to be remodelled by varying degrees as indicated by their haemodynamic properties. Structural remodelling may be a factor affecting preoperative pulmonary artery pressure. Mitral stenosis patients with severe pulmonary hypertension have significantly lower responses to sodium nitroprusside possibly due to aggradation and deposition of collagen in the artery walls, decreasing constriction and dilation, or atrophy of smooth muscle cells.




    Full Text Available BACKGROUND: Treatment of rheumatic mitral stenosis ranges from conservative medical management to closed mitral valvotomy and the more recent balloon mitral valvoplasty. This is a prospective study to compare the results of closed mitral valvotomy with percutaneous b alloon valvoplasty in 100 cases (50 patients in each group of rheumatic non - calcific mitral stenosis. MATERIALS AND METHODS: From November 2011 to March 2012, 50 patient underwent closed mitral valvotomy and another 50 had percutaneous balloon mitral valv oplasty. Balloon mitral valvoplasty was performed by Inoue technique and closed mitral valvotomy was carried out through standard anterolateral thoracotomy with transventricular gradual Tubbs dilatation. NYHA functional status, left atrial size, transmitra l end diastolic gradient, mean diastolic gradient and mitral valve area were recorded. The results at the 4 day post procedure and the results at the 6 months follow up were compared. RESULTS: Residual atrial septal defect (ASD was present in 6 patients a t 6 month follow up after balloon mitral valvoplasty. Severe mitral regurgitation occurred in 3 cases of closed mitral valvotomy group as compared to 7 cases of balloon mitral valvoplasty group. Urgent mitral valve replacement was needed in 2 patient of ba lloon mitral valvoplasty group. There was single mortality in each group. CONCLUSION: No statistical significant difference between the result of closed mitral valvotomy and balloon mitral valvoplasty but better outcome obtained by closed mitral valvotomy. Hemodynamic and functional improvement was sustained through 6 month of follow up in both groups. Procedural cost of closed mitral valvotomy was significantly lower than the procedural cost of balloon mitral valvoplasty.

[The Prince Charles Hospital, Brisbane (Australia); The University of Queensland, Brisbane (Australia)


    Rheumatic heart disease is a common cause of cardiovascular morbidity and mortality worldwide, mostly in developing countries. Mitral stenosis and atrial fibrillation often coexist, related to both structural and inflammatory changes of the mitral valve and left atrium. Both predispose to left atrial thrombus formation, commonly involving the left atrial appendage. Thromboembolism can occur, with devastating consequences. We report the case of a 62 year old woman with rheumatic heart disease resulting in mitral stenosis and atrial fibrillation. Previous treatment with warfarin resulted in life-threatening gastrointestinal bleeding and she refused further anticoagulant therapy. A combined procedure was performed, including percutaneous balloon mitral valvuloplasty and left atrial appendage occlusion device implantation with the Atritech® Watchman® device. No thromboembolic or bleeding complications were encountered at one year follow-up. Long-term follow-up in a cohort of patients will be required to evaluate the safety and efficacy of this strategy.

    Łukasz Mazurkiewicz


    Full Text Available Introduction: Atrial (ANP and B-type (BNP natriuretic peptides are hormones secreted by the heart as a response to volume expansion and pressure overload. Aim: To assess the changes of ANP and BNP after percutaneous balloon mitral valvuloplasty (PBMV and to investigate factors associated with endpoints. Material and methods: The study included 96 patients (90.7% females, age 51.6 ±12.2 years with rheumatic mitral valve stenosis (mitral valve area (MVA 1.18 (1.01–1.33 cm2, mean mitral gradient (MMG 8.2 (7.1–9.2 mm Hg, NYHA 2.09 (1.9–2.5. Patients were followed up for 29.1 months for the search of endpoints. Results : The PBMV was successful in all cases. After the procedure MVA increased (1.18–1.78 cm2, p < 0.01 and pulmonary capillary wedge pressure (PCWP decreased (29.8–21.8 mm Hg, p < 0.01. Concentration of ANP significantly rose 30 min after the PBMV (79.2 vs. 134.2 pg/ml, p = 0.012 and dropped significantly after 24 h (134.2 vs. 70.4 pg/ml, p = 0.01. Furthermore, after 36 months concentration of ANP did not differ from the baseline value (p = NS. BNP concentration at day 1 was lower than at baseline (94.5 vs. 80.2 pg/ml, p = 0.032. Moreover, during the follow-up period BNP continued to fall at all time points. In univariate analysis parameters associated with endpoint occurrence were baseline PAP (p = 0.023, baseline PCWP (p = 0.022, baseline NYHA (p = 0.041 and increase in 6-minute walk test (6MWT (p = 0.043. In multivariate analysis the only factor associated with endpoint occurrence was baseline NYHA (HR = 1.52, 95% CI: –1.3–1.91, p = 0.022. Conclusions : Patients with MS had increased levels of both BNP and ANP. Baseline NYHA class was found to be associated with outcomes after the procedure.

    Zhang-Qiang Chen


    Full Text Available Background: Tricuspid regurgitation (TR is frequently associated with severe mitral stenosis (MS, the importance of significant TR was often neglected. However, TR influences the outcome of patients. The aim of this study was to investigate the efficacy and safety of percutaneous balloon mitral valvuloplasty (PBMV procedure in rheumatic heart disease patients with mitral valve (MV stenosis and tricuspid valve regurgitation. Methods: Two hundred and twenty patients were enrolled in this study due to rheumatic heart disease with MS combined with TR. Mitral balloon catheter made in China was used to expand MV. The following parameters were measured before and after PBMV: MV area (MVA, TR area (TRA, atrial pressure and diameter, and pulmonary artery pressure (PAP. The patients were followed for 6 months to 9 years. Results: After PBMV, the MVAs increased significantly (1.7 ± 0.3 cm 2 vs. 0.9 ± 0.3 cm 2 , P 0.05. The PAP and left ventricular ejection fraction appeared no statistical difference compared with the postoperative (P > 0.05, the remaining patients without serious complications. Conclusions: PBMV is a safe and effective procedure for MS combined with TR in patients of rheumatic heart disease. It can alleviate the symptoms and reduce the size of TR. It can also improve the quality-of-life and prognosis. Its recent and mid-term efficacy is certain. While its long-term efficacy remains to be observed.

    Naser Aslanabadi


    Full Text Available Background: Percutaneous balloon mitral valvotomy (BMV is the gold standard treatment for rheumatic mitral stenosis (MS in that it causes significant changes in mitral valve area (MVA and improves leaflet mobility. Development of or increase in mitral regurgitation (MR is common after BMV. This study evaluated MR severity and its changes after BMV in Iranian patients.Methods: We prospectively evaluated consecutive patients with severe rheumatic MS undergoing BMV using the Inoue balloon technique between February 2010 and January 2013 in Madani Heart Center, Tabriz, Iran. New York Heart Association (NYHA functional class and echocardiographic and catheterization data, including MVA, mitral valve mean and peak gradient (MVPG and MVMG, left atrial (LA pressure, pulmonary artery systolic pressure (PAPs, and MR severity before and after BMV, were evaluated.Results: Totally, 105 patients (80% female at a mean age of 45.81 ± 13.37 years were enrolled. NYHA class was significantly improved after BMV: 55.2% of the patients were in NYHA functional class III before BMV compared to 36.2% after the procedure (p value < 0.001. MVA significantly increased (mean area = 0.64 ± 0.29 cm2 before BMV vs. 1.90 ± 0.22 cm2 after BMV; p value < 0.001 and PAPs, LA pressure, MVPG, and MVMG significantly decreased. MR severity did not change in 82 (78.1% patients, but it increased in 18 (17.1% and decreased in 5 (4.8% patients. Patients with increased MR had a significantly higher calcification score (2.03 ± 0.53 vs.1.50 ± 0.51; p value < 0.001 and lower MVA before BMV (0.81± 0.23 vs.0.94 ± 0.18; p value = 0.010. There were no major complications.Conclusion: In our study, BMV had excellent immediate hemodynamic and clinical results inasmuch as MR severity increased only in some patients and, interestingly, decreased in a few. Our results, underscore BMV efficacy in severe MS. The echocardiographic calcification score was useful for identifying patients likely to

  8. Inflammatory status in patients with rheumatic mitral stenosis: Guilty before and after balloon mitral valvuloplasty

    Mohamed Ahmed Abdel Rahman


    Conclusion: Inflammatory pathogenesis of rheumatic fever, suggested by hsCRP, seems fixed both before, and after BMV. A basal increase in hsCRP before BMV is related to BMV success and an acute increase immediately after BMV seems related to trauma of balloon dilatations.

    Nihat Polat


    Full Text Available Objective: In this study we aimed to investigate the relationship between the presence of atrial fibrillation (AF and serum albumin levels which is a negative acute phase protein. Methods: This study is single-center and has a retrospective design. We included patients with a diagnosis of rheumatic mitral stenosis (RMS and having serum albumin levels between 2011 and 2014. Then the patients were divided into two groups according to presence of AF. Clinical and laboratory data of these two groups were compared. Results: The study included 74 patients having the inclusion criteria. Seventy seven percent of patients were female, mean age was 44±12 years. Atrial fibrillation was detected in 34% of the patients. Hypertension presence, age, left atrial diameter, creatinine, C-reactive protein were higher in AF group while serum albumin, left ventricular ejection fraction and mean transmitral gradient was significantly lower. Multivariate logistic regression analysis showed that aging, lower albumin and anemia (respectively, odds ratio [OR]: 1.124, 95% confidence interval [CI], [1.049-1.205], OR: 0.022, 95% CI; [0.002-0.268] and OR: 5.941, 95% CI; [1.031-34.222] were found to be independent predictors of AF presence. Conclusion: Lower serum albümin levels, aging and anemia were associated with the presence of AF in patients with RMD. Low albümin levels can be a surrogate marker of increased inflammation and may serve as a risk factor for AF development. J Clin Exp Invest 2014; 5 (3: 435-440

    Lee, Kyung Soo; Yeon, Kyung Mo; Han, Man Chung [Seoul National University College of Medicine, Seoul (Korea, Republic of)


    Congenital mitral stenosis may be defined as a development abnormality of the mitral valve leaflets, commissures, interchordal spaces, papillary muscles, annulus or immediate supravalvular area producing obstruction to left ventricular filling. Authors had experience of nine case of congenital mitral stenosis confirmed by two dimensional echocardiography, angiocardiography and surgery in recent 5 years since 1979, and analyzed them with emphasis on the angiographic findings. The results are as follows: 1. Among 9 cases, 6 patients were male and 3 were female. Age distribution was from 4 month to 11 years. 2. The types of congenital mitral stenosis were 1 typical congenital mitral stenosis, 5 cases of parachute mitral valve and 3 cases of supramitral ring. 3. Angiographically typical congenital mitral stenosis showed narrowing of mitral valvular opening, parachute mitral valve displayed single large papillary muscle with narrowing valvular opening and supramitral ring disclosed semilunar shaped filling defect between left atrium and ventricle. 4. Associated cardiac and extracardiac anomalies of congenital mitral stenosis, as frequency wise, were ventricular septal defect, patent ductus arteriosus, coarctation of aorta, supra and subvalvular aortic stenosis, mitral regurgitation and double outlet right ventricle. 5. Cardiac angiography is essential to diagnose congenital mitral stenosis, but the need of two dimensional echocardiography cannot be ignored.

  18. Echocardiographic Assessment of Mantle Radiation Mitral Stenosis.

    Bastiaenen, Rachel; Sneddon, James; Sharma, Rajan


    The long-term sequelae of mantle radiotherapy include lung disease and cardiac disorders. Dyspnea on exertion is a common complaint and can be due to one or more pathologies. We describe a case of mantle radiotherapy-induced mitral stenosis, characterized by aorto-mitral continuity calcification and absent commissural fusion which precludes balloon valvotomy. The latency period is long, and this patient presented 42 years after radiotherapy. Importantly, as previously described with radiation-induced valve disease, significant mitral stenosis developed 10 years after surgery for significant aortic stenosis. Two-dimensional and three-dimensional transthoracic and transesophageal echocardiography should be considered during assessment of symptomatic survivors of Hodgkin's disease where the index of suspicion for valvular stenosis increases over time. Given the natural history of mantle radiation valvular disease, a lower threshold for surgical intervention in radiation-induced mitral stenosis may need to be considered if cardiac surgery is planned for other reasons in order to avoid repeated sternotomy in patients with prior irradiation.

    Park, Jae Hyung; Oh, Byung Hee; Park, Kyung Ju; Kim, Seung Hyup; Lee, Young Woo; Han, Man Chung [Seoul National University College of Medicine, Seoul (Korea, Republic of)


    Percutaneous balloon valvuloplasty(PBV) was successfully performed in 8 mitral stenosis patients for recent 3 months. Five patients have aortic insufficiencies also and two patients have mitral regurgitations below grade II/IV. All patients showed sinus rhythm on EKG, and had no mitral valvular calcification on echocardiography and fluoroscopy. PBV resulted in an increase in mitral valve area from 1.22{+-}0.22 to 2.57{+-}0.86 cm{sup 2}, a decrease in mean left atrial pressure from 23.4{+-}9.6 to 7.5{+-}3.4 mmHg and a decrease in mean mitral pressure gradient from 21.3{+-}9.4 to 6.8{+-}3.1 mmHg. There were no significant complications except 2 cases of newly appeared and mildly aggravated mitral regurgitation. We believe that PBV will become a treatment modality of choice replacing surgical commissurotomy or valve replacement in a group of mitral stenosis patients, because of its effectiveness and safety.

  1. Assessment of the Outcome of Severe Mitral Stenosis during Late Pregnancy


    Percutaneous balloon mitral valvuloplasty (PBMV) is one way to improve the rheumatic mitral stenosis. How does the procedure work in gravida and fetus is not very clear. We analyzed the effects and safety of PBMV operation on pregnant patients with severe rheumatic mitral stenosis. Methods Eight pregnant patients suffering from severe mitral stenosis underwent facilitated PBMV operation with Inoue balloon, and were followed up for (2. 0 ± 1.1 ) years. Contents included outcome of pregnancy, infant growth, hemodynamics, echocardiography, cardiac function,mitral valves replacement or repeat valvuloplasty. Results Mitral valve area (MVA) before, one week and one year after facilitated PBMV were (0. 84 ± 0. 21 ) cm2, ( 1.69 ± 0. 23) cm2 and ( 1.51 ± 0. 24) cm2 respectively. The transmitral pressure gradient dropped from (22. 1 ± 4. 7 ) mm Hg to (9.9 ± 3. 1 )mm Hg ( P< 0. 001 ) ( 1 mm Hg = 0. 133 kPa). After facilitated PBMV, all patients showed remarkable immediate symptomatic and hemodynamic improvement without severe mitral regurgitation. All of these patients could maintain New York heart association (NYHA) Ⅰ or Ⅱ for (2. 0 ± 1.1 ) years after the operation. Two patients demanded induced abortion concerning about the teratogenic effect of X-ray on fetus. All the other six patients continued their gestation and had full-term cesarean section without complications. Their newborns developed healthy and normally till now. Conclusions Facilitated PBMV is a feasible,safe and effective device for selected pregnant patients with mitral stenosis. The operation is well tolerated by the fetus.

  2. Clinical significance of markers of collagen metabolism in rheumatic mitral valve disease.

    Tanima Banerjee

    Full Text Available BACKGROUND: Rheumatic Heart Disease (RHD, a chronic acquired heart disorder results from Acute Rheumatic Fever. It is a major public health concern in developing countries. In RHD, mostly the valves get affected. The present study investigated whether extracellular matrix remodelling in rheumatic valve leads to altered levels of collagen metabolism markers and if such markers can be clinically used to diagnose or monitor disease progression. METHODOLOGY: This is a case control study comprising 118 subjects. It included 77 cases and 41 healthy controls. Cases were classified into two groups- Mitral Stenosis (MS and Mitral Regurgitation (MR. Carboxy-terminal propeptide of type I procollagen (PICP, amino-terminal propeptide of type III procollagen (PIIINP, total Matrix Metalloproteinase-1(MMP-1 and Tissue Inhibitor of Metalloproteinase-1 (TIMP-1 were assessed. Histopathology studies were performed on excised mitral valve leaflets. A p value 459 ng/mL for PICP provided 91% sensitivity, 90% specificity and a likelihood ratio of 9 in diagnosing RHD. Histopathology analysis revealed inflammation, scarring, neovascularisation and extensive leaflet fibrosis in diseased mitral valve. CONCLUSIONS: Levels of collagen metabolism markers correlated with echocardiographic parameters for RHD diagnosis.

    Poyraz, Esra; Öz, Tuğba Kemaloğlu; Zeren, Gönül; Güvenç, Tolga Sinan; Dönmez, Cevdet; Can, Fatma; Güvenç, Rengin Çetin; Dayı, Şennur Ünal


    In a fraction of patients with mild mitral stenosis, left ventricular systolic function deteriorates despite the lack of hemodynamic load imposed by the dysfunctioning valve. Neither the predisposing factors nor the earlier changes in left ventricular contractility were understood adequately. In the present study we aimed to evaluate left ventricular mechanics using three-dimensional (3D) speckle tracking echocardiography. A total of 31 patients with mild rheumatic mitral stenosis and 27 healthy controls were enrolled to the study. All subjects included to the study underwent echocardiographic examination to collect data for two- and three-dimensional speckle-tracking based stain, twist angle and torsion measurements. Data was analyzed offline with a echocardiographic data analysis software. Patients with rheumatic mild MS had lower global longitudinal (p < 0.001) circumferential (p = 0.02) and radial (p < 0.01) strain compared to controls, despite ejection fraction was similar for both groups [(p = 0.45) for three dimensional and (p = 0.37) for two dimensional measurement]. While the twist angle was not significantly different between groups (p = 0.11), left ventricular torsion was significantly higher in mitral stenosis group (p = 0.03). All strain values had a weak but significant positive correlation with mitral valve area measured with planimetry. Subclinical left ventricular systolic dysfunction develops at an early stage in rheumatic mitral stenosis. Further work is needed to elucidate patients at risk for developing overt systolic dysfunction.

    Rheumatic Heart Disease (RHD), a chronic acquired heart disorder results from Acute Rheumatic Fever. It is a major public health concern in developing countries. In RHD, mostly the valves get affected. The present study investigated whether extracellular matrix remodelling in rheumatic valve leads to altered levels of collagen metabolism markers and if such markers can be clinically used to diagnose or monitor disease progression. This is a case control study comprising 118 subjects. It included 77 cases and 41 healthy controls. Cases were classified into two groups- Mitral Stenosis (MS) and Mitral Regurgitation (MR). Carboxy-terminal propeptide of type I procollagen (PICP), amino-terminal propeptide of type III procollagen (PIIINP), total Matrix Metalloproteinase-1(MMP-1) and Tissue Inhibitor of Metalloproteinase-1 (TIMP-1) were assessed. Histopathology studies were performed on excised mitral valve leaflets. A p value valve replacement (pvalve area (r = -0.40; r = 0.49 respectively) and pulmonary artery systolic pressure (r = 0.49; r = -0.49 respectively); while in MR they correlated with left ventricular internal diastolic (r = 0.68; r = -0.48 respectively) and systolic diameters (r = 0.65; r = -0.55 respectively). Receiver operating characteristic curve analysis established PICP as a better marker (AUC = 0.95; 95% CI = 0.91-0.99; p459 ng/mL for PICP provided 91% sensitivity, 90% specificity and a likelihood ratio of 9 in diagnosing RHD. Histopathology analysis revealed inflammation, scarring, neovascularisation and extensive leaflet fibrosis in diseased mitral valve. Levels of collagen metabolism markers correlated with echocardiographic parameters for RHD diagnosis.

  5. Regression of severe tricuspid regurgitation after mitral balloon valvotomy for severe mitral stenosis

    Mohamed Eid Fawzy


    Conclusions: Regression of significant TR after successful MBV in patients with severe mitral stenosis was observed in patients who had severe pulmonary hypertension. This improvement in TR occurred even in the presence of organic tricuspid valve disease.

  6. Progression to calcific mitral stenosis in end-stage renal disease.

    D'Cruz, I A; Madu, E C


    A 59-year-old man with end-stage renal disease and on hemodialysis had neither mitral stenosis nor mitral calcification on echo-Doppler examination in 1989, but had extensive mitral calcification and definite mitral stenosis on conventional and transesophageal echocardiography in 1994. The left ventricle had marked concentric hypertrophy. To our knowledge this is the first documentation of the development of calcific mitral stenosis in end-stage renal disease revealed by serial echo-Doppler studies.

  7. Transapical Mitral Valve Replacement for Mixed Native Mitral Stenosis and Regurgitation.

    Bedzra, Edo; Don, Creighton W; Reisman, Mark; Aldea, Gabriel S


    A 71-year-old man presented with New York Heart Association (NYHA) class IV heart failure. He had undergone transapical mitral valve replacement for mixed mitral stenosis and mitral regurgitation. At the 1 month follow-up, the patient reported symptom resolution. An echocardiogram revealed a low gradient and no regurgitation. Our case shows that with careful multidisciplinary evaluation, preoperative planning, and patient selection, percutaneous mitral intervention can become an alternative therapy for high-risk patients who cannot undergo conventional surgical therapy.

  10. Our First Experience on Percutaneous Transvenous Mitral Commissurotomy (PTMC: Case Report

    Aziz Karabulut


    Full Text Available Rheumatic heart disease remains a significant healt problem especially in devaloping countries. In rheumatic heart disease, mitral valve is affected in nearly all cases; mitral stenosis is the most common lesion. Percutaneous Transvenous Mitral Commissurotomy (PTMC is an important tool in the treatment of rheumatic mitral stenosis. In this study, our first PTMC case is presented, and the PTMC indications and the comparison of patients underwent PTMC with those patients underwent surgical intervention is discussed with the literature.

  11. 5. Mitral valve replacement for mitral stenosis: 15 years single center experience

    A. Arifi


    Full Text Available Mitral valve replacement (MVR with either a bioprosthetic or a mechanical valve is the treatment of choice for severe mitral stenosis. This study aimed to evaluate and compare the early and late outcome of mitral valve replacement (mechanical versus bioprosthetic for severe mitral stenosis. A retrospective cohort study was performed on prospectively collected data involving mitral stenosis patients who have undergone MVR with either bioprosthetic (BMV (n = 50 or mechanical (MMV (n = 145 valves in our institute from 1999 to 2012. Data were analyzed for early and late mortality, NYHA functional classes, stroke, early and late valve-related complications, and survival. Chi Square test, logistic regression, Kaplan Meier curve, and dependent proportions tests were performed. A total of 195 patients were included in the study with a follow-up of 190 patients (97.5%. One patient died early post-operatively; twelve patients died late in the post-operative period, BMV group (6 and the MMV (6. The Late mortality had significantly associated with post-op stroke (p < 0.001 and post-op NYHA classes III and IV (p = 0.002. Post-op NYHA class was significantly associated with age (p = 0.003, pulmonary disease (p = 0.02, mitral valve implant type (p = 0.01, and post-op stroke (p = 0.02; 14 patients had strokes in the MMV (9 and in the BMV (5 groups. NYHA classes were significantly better after the replacement surgeries (p < 0.001. Bioprosthetic valves were significantly associated with worse survival (p = 0.03, worse NYHA post-op (p = 0.01, and more re-operations (p = 0.006. Survival was significantly better with mechanical valves (p = 0.03. When the two groups were matched for age and mitral regurgitation, the analysis revealed that bioprosthetic valves were significantly associated with re-operations (p = 0.02 but not significantly associated with worse survival (p = 0.4 or worse NYHA (p = 0.4.

    吴玉付; 李醒三; 何显菁; 曾晓聪


    Objective To determine the relationship between the rennin-angiotensin-aldosterone systems(RAAS)and left atrial structure remodeling in patients with rheumatic mitral stenosis.Methods The patients with rheumatic mitral stenosis were divided into two groups according to atrial fibrillation:sinus rhythm group(SR group,n=25)and atrial fibrillation group(AF group,n=30).17 normal subjects were selected as normal control group(NC).The plasma concentration of renin,angiotonin Ⅱ(Ang Ⅱ)and aldosterone(Ald)were measured by radioimmunoassay(RIA).Results The average value of the left atrial diameter in AF group was significantly greater than that of both SR group and NC group,increased by 16.9%[(57.71±8.07)mm vs.(48.48±5.05)mm,P<0.01)]and 87.8%(57.71±8.07 mm vs.30.18±2.85 mm,P<0.01)respectively.Compared with NC group,the left atrial diameter of SR group was also significantly greater,elevated by 60.6%[(48.48±5.05)mm vs.(30.18±2.85)mm,P<0.01)].The level of plasma rennin activity(PRA),Ang Ⅱ and Aid in AF and SR patients was significantly higher than those of NC subjects(P<0.01),and compared with SR patients,the level of those in AF patients was also significantly increased(P<0.01,P<0.05).Pearson correlation analysis revealed a positive correlation between the plasma level of PRA,Ang Ⅱ or Ald and the value of the left atrial diameter(r=0.277,0.485,0.431,P<0.05,P<0.01,P<0.01).Multiple liner stepwise regression analysis showed that plasma Ang Ⅱ and Ald were the important risk factors that affected left atrial diameter in patients with rheumatic mitral stenosis(Bate=0.362,0.261,P<0.01,P<0.05).Conclusion Patients with rheumatic mitral stenosis are characterized by the activation of circulating RAAS,and the plasma Ang Ⅱ and Ald may contribute to left atrial structure remodeling.%目的 研究风湿性心脏病(风心病)二尖瓣狭窄(MS)患者血浆肾素血管紧张素醛固酮系统的变化,并探讨其与左心房重构的关系.方法 MS

  13. Undersized annuloplasty for functional mitral regurgitation: is it responsible for clinically relevant mitral stenosis during exercise?

    Grimaldi, Antonio; De Bonis, Michele; Pappalardo, Federico; Taramasso, Maurizio; Verzini, Alessandro; Calabrese, Maria Chiara; Maisano, Francesco; Alfieri, Ottavio


    The study aim was to assess if an undersized mitral annuloplasty for functional mitral regurgitation (FMR) in dilated cardiomyopathy can determine a clinically relevant mitral stenosis during exercise. Both, rest and stress echocardiography were performed in 12 patients submitted to an undersized ring annuloplasty for FMR in dilated cardiomyopathy. The mean ring size was 27 +/- 1.3 mm. All patients were in NYHA functional classes I-II, were in stable sinus rhythm, and without significant residual mitral regurgitation (grade stroke volume (63 +/- 15 versus 77 +/- 14 ml, p FMR. Stress echocardiography represents a valuable tool to assess an appropriate cardiac response to exercise and to detect a significant exercise-induced pulmonary hypertension after undersized annuloplasty ring surgery.

    Full Text Available A search for associations between allelic variations of immune response genes, and mitral stenosis associated with rheumatic heart disease, represents an important task when studying the pathogenesis of cardiovascular disorders among inhabitants of large industrial regions in Western Siberia. Among multiple polymorphisms of interleukin-encoding genes, a particular attention should be paid to association studies of some intronic polymorphisms with variable numbers of tandem repeats (VNTR. In this respect, genotyping of interleukin 1 receptor antagonist genes (IL-1ra86bp VNTR and interleukin 4 (IL-470bp VNTR has shown positive associations between the intron 2 IL-1ra*3R/3R microsatellite polymorphism, intron 3 IL-4*2R/2R variant, and the risk of mitral stenosis development in patients with rheumatic heart disease (OR = 12.71; p = 0.0001.  

  15. Anuloplastia sem suporte para tratamento da insuficiência mitral reumática Non-supported mitral annuloplasty technique for treatment of rheumatic mitral insufficiency

    Renato A. K Kalil


    sem suporte anular profético, com resultados tardios comparáveis àqueles obtidos por técnicas mais complexas. Isto tem importância no tratamento de crianças e adultos jovens, especialmente no sexo feminino, quando se deseja evitar implante de próteses mecânicas.Since 1974 a non-supported mitral annuloplasty technique has been employed for treatment of pure mitral regurgitation (PMR, in a population that was predominantly young and of rheumatic ethnology. An evaluation of late results forms the basis of this report. There were 154 patients operated on for PMR, 55 (36% male and 99 (64% female. Mean age was 36 ± 16 (5 to 73 years. Associated lesions were: 47 aortic, 21 tricuspid and 2 ASDs (atrial aptal defects. Cases with concomitant mitral stenosis were not included. Properative functional class was I-II in 19% and III-IV in 81%. The cardiothoracic ratio was 0.61 ± 0.10. All patients were submitted to an unsupported mitral annuloplastic procedure, similar to that described by WOOLER, that consisted in reduction of the mural portion of the annulus obtained with the application of two buttressed mattress sutures at the comissures without compromisse to the width of the septal leaflet. When necessary, additional chordal procedures were performed. No patients received ring or posterior annular support. Residual late systolic murmur was present in 48%. Late complications were: systemic thromboembolism 5.8% (1/3 with aortic prosthesis, infective endocardites 1.3% and pulmonary thromboembolism 0.7%. Postoperative functional class was I-II in 84% and III-IV in 16%. Cardiothoracic ratio was 0.58 ± 0.10. Actuarial probability of late survival was 79.5 ± 5.3% at 10 years and 71.0 ± 7.4% at 14 years. Event free survival was 67.9 ± 8.9% at 10 years and 56.1 ± 11.7% at 14 years. Rheumatic mitral regurgitation can be effectively treated by annuloplasty without prosthetic annular support with late results comparable to those obtained with more complicated procedures

  16. Anesthetic management for surgical repair of Ebstein′s anomaly along with coexistent Wolff-Parkinson-White syndrome in a patient with severe mitral stenosis

    Sinha Prabhat


    Full Text Available Ebstein′s anomaly (EA is the most common cause of congenital tricuspid regurgitation. The associated anomalies commonly seen are atrial septal defect or patent foramen ovale and accessory conduction pathways. Its association with coexisting mitral stenosis (MS has uncommonly been described. The hemodynamic consequences and anesthetic implications, of a combination of EA and rheumatic MS, have not so far been discussed in the literature. We report successful anesthetic management of a repair of EA and mitral valve replacement in a patient with coexisting Wolff-Parkinson-White (WPW syndrome.

  20. Repeat Minimally Invasive Mitral Valve Replacement for Recurrent Mitral Stenosis after OMC in Patients Who Decline Blood Product Transfusion for Religious Reasons.

    Ito, Yujiro; Nakamura, Yoshitsugu; Tagusari, Osamu; Yoshida, Shigehiko


    Cardiac surgery for Jehovah's Witness (JW) patients is considered to be high risk because of patients' refusal to receive blood transfusion. We report a successful mitral valve replacement for recurrent mitral stenosis after OMC with minimally invasive right thoracotomy, without any transfusion of allogeneic blood or blood products. This minimally invasive mitral valve replacement through right thoracotomy was an excellent approach for JW patients.

  1. [Discrete type subaortic stenosis disclosed by hemolytic anemia after aortic and mitral valve replacement].

    Kawahara, Yu; Inage, Yuichi; Masaki, Naoki; Kobayashi, Yuriko; Jinbu, Ryota; Toyama, Shuji; Fukasawa, Manabu


    We report a case of discrete type subaortic stenosis disclosed by hemolytic anemia 7 years after aortic and mitral prosthetic valve replacement. A 53-year-old female complained of general fatigue, dyspnea, macrohematuria and hemolysis. She had undergone aortic valve replacement for non-coronary cusp perforation 15 years before, and mitral valve replacement and tricuspid annuloplasty 7 years before. Echocardiography showed mitral prosthetic valve regurgitation (III/IV degree) and symptomatic hemolysis might be caused by accelerated blood flow through the prosthetic valve. A mild aortic stenosis (peak flow verocity:3.73 m/s) was also pointed out. The redo double valve replacement was performed. Intraoperative findings showed discrete type subaortic stenosis due to extensive pannus formation, but that the previously implanted prosthetic valves were intact. The blood flow biased by the interference of the subaortic stenosis might have obstructed closure of the mitral prosthetic valve and caused mitral regurgitation. Postoperatively, hemolysis and mitral regurgitation were diminished, and aortic stenosis was improved.

  4. Rheumatic mitral regurgitation. The case for annuloplasty in the pediatric age group.

    Stevenson, J G; Kawabori, I; Morgan, B C; Dillard, D H; Merendino, K A; Guntheroth, W G


    Eight youngsters (five female, three male, ages 10 to 19 years, mean 15 years) with isolated severe rheumatic mitral regurgitation have been subjected to mitral annuloplasty because of limiting symptoms and prominent ECG and X-ray changes. They have been followed for up to 11 years (mean 3.7 years), and 7 have had excellent results. An early (1961) patient had a small annulus and was not a favorable candidate; he had only transient improvement. Seven are greatly improved, have decreased cardiac size (often dramatic), and have improved ECG's. One has undergone successful pregnancy, and none has been limited in activities. The extent and duration of improvement, lack of mortality, and resumption of normal activities by these youngsters indicate surgical success. The essence of childhood and youth is activity and the future life span hopefully long; hence, annuloplasty would appear to be the procedure of choice for severe rheumatic mitral regurgitation in the pediatric age group, avoiding the usual need for anticoagulation and uncertain long-term results associated with mitral valve replacement.

  5. Valvoplastia mitral em pacientes jovens com cardiopatia reumática Mitral valvuloplasty in young patients with rheumatic heart disease

    Fernando Antônio Fantini


    Full Text Available No período, de setembro de 1988 a janeiro de 1992, 56 pacientes com até 20 anos de idade (4 a 20 anos, média de 12,7 com insuficiência mitral pura ou predominante de etiologia reumática foram submetidos a valvoplastia mitral. Noventa e quatro por cento dos pacientes estavam em classe funcional III ou IV da NYHA. A técnica cirúrgica básica usada em todos os pacientes foi a anuloplastia assimétrica preconizada por Reed et alii 31, associada em 69,7% dos casos a outros procedimentos sobre as cúspides e aparelho subvalvar mitral. Dois pacientes foram submetidos, concomitantemente, a plastia da valva tricúspide e 4 a troca da valva aórtica. Estudo ecodopplercardiográfico per-operatório foi utilizado após a correção em todos os casos e mostrou ausência de lesões residuais em 76% dos pacientes e insuficiência mitral discreta nos demais. Náo houve mortalidade hospitalar. Ecopplercardiograma realizado antes da alta hospitalar mostrou boa correlação com o estudo per-operatório. Foi possível colher informações do seguimento tardio de 53 pacientes. Ocorreu 1 óbito tardio três meses após a cirurgia, por morte súbita. Quatro pacientes foram reoperados e submetidos a troca valvar: uma paciente no 4º mês de pós-operatório (PO, por falha primária do procedimento, e outros três no 6º, 34º e 38º meses de PO, por comprovada recidiva da cardite reumática. Os demais encontram-se em classe funcional I e II (NYHA. Concluímos, baseados nos resultados apresentados, que a anuloplastia mitral assimétrica é um excelente procedimento para pacientes jovens com valvopatia reumática, constituindo-se numa boa alternativa à troca de valva ou implante de anéis, sendo, no entanto, extremamente importante o controle de recidivas da doença reumática.From September 1988 to July 1990, 56 patients under 20 years of age (mean 12.7 ± 5.12 years with pure or predominant mitral valve regurgitation secondary to rheumatic valve disease

  6. Mitral valve replacement in children and adolescents with rheumatic heart disease.

    Stanley, J; Munsi, S; Sukumar, I P; Cherian, G


    To our knowledge, no documented hemodynamic studies in larger series of young patients undergoing valve replacement for rheumatic valvular disease have been reported previously. It seems to us that the natural history of rheumatic heart disease in India often follows a rapid and fulminant course which makes an aggressive surgical approach mandatory. An operative mortality of 22 % was seen in this series. Pronounced cardiac disability together with the poor general condition and the low nutritional status contributed in no small measure to this figure. Patients have been followed for periods ranging from 6 months to 6 years following corrective surgery. A remarkable absence of thrombo-embolic phenomena was a striking feature in the follow-up. There has been no evidence of rheumatic reactivation in any of these patients. This communication reinforces the beneficial results of valve replacement even at this young age when severe mitral incompetence exists refractory to medical treatment.

  7. Infective endocarditis causing mitral valve stenosis - a rare but deadly complication: a case report.

    Hart, Michael A; Shroff, Gautam R


    Infective endocarditis rarely causes mitral valve stenosis. When present, it has the potential to cause severe hemodynamic decompensation and death. There are only 15 reported cases in the literature of mitral prosthetic valve bacterial endocarditis causing stenosis by obstruction. This case is even more unusual due to the mechanism by which functional mitral stenosis occurred. We report a case of a 23-year-old white woman with a history of intravenous drug abuse who presented with acute heart failure. Transthoracic echocardiography failed to show valvular vegetation, but high clinical suspicion led to transesophageal imaging that demonstrated infiltrative prosthetic valve endocarditis causing severe mitral stenosis. Despite extensive efforts from a multidisciplinary team, she died as a result of her critical illness. The discussion of this case highlights endocarditis physiology, the notable absence of stenosis in modified Duke criteria, and the utility of transesophageal echocardiography in clinching a diagnosis. It advances our knowledge of how endocarditis manifests, and serves as a valuable lesson for clinicians treating similar patients who present with stenosis but no regurgitation on transthoracic imaging, as a decision to forego a transesophageal echocardiography could cause this serious complication of endocarditis to be missed.

  8. Late calcific mitral stenosis after MitraClip procedure in a dialysis-dependent patient.

    Pope, Nicolas H; Lim, Scott; Ailawadi, Gorav


    The EVEREST II trial investigated the MitraClip (Abbott Vascular, Menlo Park, CA) in patients with severe mitral regurgitation (MR) undergoing surgical procedures. Although mitral stenosis was not reported in this cohort, this trial excluded patients receiving dialysis. We report a case of a 43-year-old HIV-positive, dialysis-dependent patient with nonischemic cardiomyopathy and severe MR, who was considered at high operative risk because of frailty. She was treated with a MitraClip as part of the REALISM high-risk registry. Her symptomatic MR improved but severe symptomatic mitral stenosis developed 28 months after the MitraClip procedure. At that point, she was felt to be a better operative candidate but required open mitral valve replacement. Pathologic examination demonstrated significant calcification of the leaflets around the MitraClip devices.

  9. Dextrocardia, situs inversus and severe mitral stenosis in a pregnant woman: successful closed commissurotomy.

    Said, S A; Veerbeek, A; van der Wieken, L R


    A 16-weeks' pregnant woman with situs inversus and dextrocardia underwent successful closed commissurotomy for severe mitral stenosis. The electrocardiogram revealed sinus rhythm with right axis deviation and progressive diminishing of QRS amplitude towards the left precordial leads. The chest X-ray showed dextrocardia with situs inversus. Doppler echocardiography depicted severe mitral stenosis; the mitral valve area increased from 0.9 cm2 pre-operatively to 1.8 cm2 post-operatively with mild increase of mitral regurgitation from grade I to II post-valvotomy. She also had associated mild functional tricuspid insufficiency and moderate pulmonary hypertension. No thrombo-embolic complications occurred intra- or post-operatively. There was no evidence of either clinical or Doppler restenosis. The course of pregnancy was uneventful. At 39 weeks a healthy baby was vaginally delivered. The patient is still free of cardiac symptoms.

  10. An unusual case of hematuria in a young female: renal artery embolism, mitral stenosis, and sinus rhythm

    Ashok Kumar


    Full Text Available Renal artery embolism (RAE is an uncommon entity that is most often secondary to a cardiac source. Most reported cases have been in patients with underlying atrial fibrillation (AF, and occurrence of RAE, especially in patients with valvular heart disease, and sinus rhythm is very rare. We describe an unusual case of a young female who presented with sudden onset right flank pain, vomiting, anorexia, and hematuria, and was found to have thrombotic occlusion of the distal right renal artery. Although she denied any previous cardiac history, detailed cardiovascular examination revealed the presence of severe rheumatic mitral stenosis without any evidence of AF or left atrial clot. She was initially managed conservatively using low molecular weight heparin followed by oral anticoagulation with resolution of symptoms. A successful balloon mitral valvotomy was performed six weeks later. The patient is asymptomatic at her last follow-up of six months with preserved renal function. In symptomatic patients, clinicians need to consider the possibility of RAE even in patients of valvular heart disease with underlying sinus rhythm. Appropriate management of the underlying cardiac condition is imperative since embolism may be recurrent leading to compromise of renal function, if left untreated.

  11. Radiotherapy-induced concomitant coronary artery stenosis and mitral valve disease.

    Akboga, Mehmet Kadri; Akyel, Ahmet; Sahinarslan, Asife; Cengel, Atiye


    Radiotherapy is extensively used in the treatment of Hodgkin's disease. One of its untoward effects is on heart. Coronary arteries and heart valves can be adversely affected from radiotherapy. However, co-existence of both conditions is very rare. In this report, we present a patient with Hodgkin's disease who developed both coronary artery stenosis and severe mitral valve regurgitation after radiotherapy.

  12. Incidental moderate mitral regurgitation in patients undergoing aortic valve replacement for aortic stenosis: review of guidelines and current evidence.

    Ramakrishna, Harish; Kohl, Benjamin A; Jassar, Arminder S; Augoustides, John G T


    Recent evidence has shown that moderate mitral regurgitation is common and clinically relevant in patients presenting for surgical and transcatheter aortic valve replacement for aortic stenosis. Prospective multicenter clinical trials are now indicated to resolve the clinical equipoise about whether or not mitral valve intervention also is indicated at the time of aortic valve intervention. Advances in three-dimensional transesophageal echocardiography, transcatheter mitral interventions, and surgical aortic valve replacement, including the advent of sutureless valves, likely will expand the therapeutic possibilities for moderate mitral regurgitation in the setting of aortic valve interventions for severe aortic stenosis.

  13. Severe Bioprosthetic Mitral Valve Stenosis and Heart Failure in a Young Woman with Systemic Lupus Erythematosus

    Siddharth Wartak


    Full Text Available A 23-year-old African American woman with a past medical history of systemic lupus erythematous (SLE, secondary hypertension, and end stage renal disease (ESRD on hemodialysis for eight years was stable until she developed symptomatic severe mitral regurgitation with preserved ejection fraction. She underwent a bioprosthetic mitral valve replacement (MVR at outside hospital. However, within a year of her surgery, she presented to our hospital with NYHA class IV symptoms. She was treated for heart failure but in view of her persistent symptoms and low EF was considered for heart and kidney transplant. This was a challenge in view of her history of lupus. We presumed that her stenosis of bioprosthetic valve was secondary to lupus and renal disease. We hypothesized that her low ejection fraction was secondary to mitral stenosis and potentially reversible. We performed a dobutamine stress echocardiogram, which revealed an improved ejection fraction to more than 50% and confirmed preserved inotropic contractile reserve of her myocardium. Based on this finding, she underwent a metallic mitral valve and tricuspid valve replacement. Following surgery, her symptoms completely resolved. This case highlights the pathophysiology of lupus causing stenosis of prosthetic valves and low ejection cardiomyopathy.

    Degenerative mitral stenosis (DMS) is characterized by decreased mitral valve (MV) orifice area and increased transmitral pressure gradient due to chronic noninflammatory degeneration and subsequent calcification of the fibrous mitral annulus and the MV leaflets. The "true" prevalence of DMS in the general population is unknown. DMS predominantly affects elderly individuals, many of whom have multiple other comorbidities. Transcatheter MV replacement techniques, although their long-term outcomes are yet to be tested, have been gaining popularity and may emerge as more effective and relatively safer treatment option for patients with DMS. Echocardiography is the primary imaging modality for evaluation of DMS and related hemodynamic abnormalities such as increased transmitral pressure gradient and pulmonary arterial pressure. Classic echocardiographic techniques used for evaluation of mitral stenosis (pressure half time, proximal isovelocity surface area, continuity equation, and MV area planimetry) lack validation for DMS. Direct planimetry with 3-dimensional echocardiography and color flow Doppler is a reasonable technique for determining MV area in DMS. Cardiac computed tomography is an essential tool for planning potential interventions or surgeries for DMS. This article reviews the current concepts on mitral annular calcification and its role in DMS. We then discuss the epidemiology, natural history, differential diagnosis, mechanisms, and echocardiographic assessment of DMS.

    A 45-year-old woman with antiphospholipid antibody syndrome (APS) and systemic lupus erythematosus was admitted because of severe dyspnea. She had undergone mitral valve replacement (MVR) using a Mosaic bioprosthesis for infective endocarditis 9 years previously. She developed congestive heart failure secondary to mitral bioprosthetic valve stenosis resulting from relatively early structural valve deterioration. She underwent a second MVR using a mechanical valve prosthesis. The explanted bioprosthesis showed marked pannus formation and mineralization with fibrin thrombus formation, especially on the outflow surfaces of the leaflets. After the second operation, she was discharged without APS-related thromboembolic events under meticulous anticoagulant and antiplatelet therapies.

    Aim: Peak atrial longitudinal strain (PALS) is used to evaluate left atrium (LA) function in patients with mitral stenosis (MS), before and after percutaneous transmitral commissurotomy (PTMC) and mitral valve replacement (MVR). Methods: Patients with severe symptomatic MS, who were referred to our echocardiographic laboratory for a diagnostic examination before cardiac surgery or PTMC from October of 2014 to October of 2015, were included in the study. Result: The peak systolic global LA strain improved post-PTMC (P < 0.001) and post-MVR (P = 0.012). This difference was statistically highly significant. Conclusion: PALS is impaired in patients with severe symptomatic MS and improved acutely after treatment and may be a good indicator of LA function and may predict the right time for intervention on mitral valve.

    Plamna dynorphin Al-13 levels were measured in 33 patients with mitral stenosis before and afteT percutaneous balloon mitral eommimurotomy (PBMC). The results show that the basal levels of plasma dynorphin in blood from the antecubital vein in the patients were signifieantly higher than those in 31 healthy control subjects. The increase in circulating dynorphin closely correlated with the functional cardiac status and the presence of atrial fibrillation. Ten to fifteen minutes after PBMC, plasma dynorphln levels in blood from the femoral vein increased significantly. Seventy-two hours after the procedure, the levels of plasma dynorphin in blood from the anteeubltal vein had decreased significantly, but they did not decrease to the normal range. Plasmm dynorphin levels in blood from the femoral vein were positively correlated with the mean laft atrial pressure and the mean right atrial pressure before the first balloon inflation. Plasma dynorphin levels in blood from the anteeubital vein were positively correlated with the heart rate and the mean transmittal presstme gradient,and negatively with the mitral valve area before and 72 hours after PBMC.

  19. A comparison of hemodynamic effects of levosimendan and dobutamine in patients undergoing mitral valve repair / replacement for severe mitral stenosis

    Ravikumar Gandham


    Full Text Available Aims and Objectives: We aimed to compare the hemodynamic effects of levosimendan and dobutamine in patients undergoing mitral valve surgery on cardiopulmonary bypass (CPB. Materials and Methods: Sixty patients were divided into 2 groups of 30 each. Group-L patients received levosimendan 0.1 μg/kg/min and Group-D patients received dobutamine 5 μg/kg/min while weaning off CPB. Additional inotrope and/or vasoconstrictor were started based on hemodynamic parameters. Hemodynamic data were collected at the end and at 30 minutes after CPB, thereafter at 6, 12, 24, and 36 hours post-CPB. Mean arterial pressure (MAP, central venous pressure (CVP, heart rate (HR, cardiac index (CI, systemic vascular resistance index (SVRI, and lactate levels were measured. Results: Group-L showed increased requirement of inotropes and vasoconstrictors. The SVRI, CVP, and MAP were reduced more in Group-L. The CI was low in Group-L in the initial period when compared to Group-D. Later Group-L patients showed a statistically significant increase in CI even after 12 hrs of discontinuation of levosimendan infusion. The HR was increased more in Group-D. Lactate levels, intensive care unit stay, and duration of ventilation were similar in both groups. Conclusions: Levosimendan 0.1 μg/kg/min compared to dobutamine 5 μg/kg/min showed more vasodilation and lesser inotropic activity in patients undergoing mitral valve surgery for mitral stenosis. Levosimendan compared to dobutamine showed a statistically significant increase in CI even after 12 hrs of discontinuation. The requirement of another inotrope or vasopressor was frequent in levosimendan group.

  20. Effectiveness of balloon valvuloplasty for palliation of mitral stenosis after repair of atrioventricular canal defects.

    Robinson, Joshua D; Marx, Gerald R; Del Nido, Pedro J; Lock, James E; McElhinney, Doff B


    Closure of a mitral valve (MV) cleft, small left-sided cardiac structures, and ventricular imbalance all may contribute to mitral stenosis (MS) after repair of atrioventricular canal (AVC) defects. MV replacement is the traditional therapy but carries high risk in young children. The utility of balloon mitral valvuloplasty (BMV) in postoperative MS is not established and may offer alternative therapy or palliation. Since 1996, 10 patients with repaired AVC defects have undergone BMV at a median age of 2.5 years (range 8 months to 14 years), a median of 2 years after AVC repair. At catheterization, the median value of mean MS gradients was 16 mm Hg (range 12 to 22) and was reduced by 34% after BMV. Before BMV, there was mild mitral regurgitation in 9 of 10 patients, which increased to severe in 1 patient. All patients were alive at follow-up (median 5.4 years). Repeat BMV was performed in 4 patients, 10 weeks to 18 months after initial BMV. One patient underwent surgical valvuloplasty; 3 underwent MV replacement 2, 3, and 28 months after BMV. In the 6 patients (60%) with a native MV at most recent follow-up (median 3.2 years), the mean Doppler MS gradient was 9 mm Hg, the median weight had doubled, and weight percentile had increased significantly. In conclusion, BMV provides relief of MS in most patients with repaired AVC defects; marked increases in mitral regurgitation are uncommon. Because BMV can incompletely relieve obstruction and increase mitral regurgitation, it will not be definitive in most patients but will usually delay MV replacement to accommodate a larger prosthesis.

  1. [Calculation of the mitral valve area with the proximal convergent flow method with Doppler-color in patients with mitral stenosis].

    Aguilar, J A; Summerson, C; Flores, D; Espinosa, R A; Enciso, R; Badui, E; Hurtado, R


    In this study we evaluate prospectively a new color Doppler method for calculating the mitral valve area based on identifying a blue-red aliasing interfase proximal to the orifice, corresponding to the flow convergence region (FCR). This method can be used to calculate areas using the continuity equation. We studied 61 patients with stenosis. The mitral valve area was calculated using pressure half-time (PHT) Doppler method which were compared with values that obtained by the FCR method, according to the following formula. AVM (cm2) = 2 pi r2 x VN/Vmax; where "r" is the FCR radius measured from the orifice to the first color aliasing (blue-red interface); VN is Nyquist velocity and Vmax is the peak flow velocity by continuous wave Doppler. Twenty three patients had pure mitral stenosis and 38 double mitral lesion. Twenty patients were on sinus rhythm while 41 in atrial fibrillation. Calculated mitral valve area using the FCR method correlated well with mitral valve area determined by PHT method at a correlation coefficient of r = 0.96 (y = 0.097 x + 54.9, SEE = 0.10 cm2, p < 0.001). MVA by FCR ranged from 0.4 to 2.5 cm2 (mean = 1.19 cm2). MVA by PHT ranged from 0.42 to 2.48 cm2 (mean = 1.15 cm2). Color Doppler FCR method provides an accurate estimate of effective mitral valve area and may be useful as an alternative to the pressure half-time method. The calculated mitral valve area by the FCR method is not influenced by the presence of mitral regurgitation nor atrial fibrillation.

    Sattarzadeh Badkoubeh R


    Full Text Available "nBackground: Estimation of Left Ventricular End Diastolic Pressure (LVEDP among patients with Mitral Stenosis (MS helps to diagnose diastolic dysfunction and to explain their symptoms. However, Conventional Doppler measurements have limitation in predicting of LVEDP. This study sought to establish whether the correlation between measurements derived from Tissue Doppler echocardiography and LVEDP remains valid in the setting of severe mitral stenosis. "n"nMethods: Thirty three patients with moderate to severe MS who had indication for left heart catheterization enrolled during 1387-88 in Imam Khomeini Hospital in Tehran, Iran. The mean diastolic transmitral pressure gradient and mitral valve area (MVA were calculated, and Two-dimensional, M-mode, color Doppler and tissue Doppler Imaging indices such as: early diastolic mitral inflow velocity (E, annular early diastolic velocity (Ea, E/A ratio, Isovolemic relaxation time (IVRT, Pulmonary Vein systolic and diastolic flow velocities, Velocity Propagation, LA size, TE-Ea, Tei Index were obtained in maximum three hours before cardiac catheterization. The echocardiography analysis was performed offline without knowledge of hemodynamic data Linear correlation and multiple linear regression were used for analysis. p< 0.05 was considered significant. "n"nResults: In univariate analysis, E/Ea was associated with LVEDP significantly (p = 0.04, r = 0.38. There was also a significant correlation between TE-Ea and LVDP (p = 0.01, r = -0.44. In multiple linear regression Tei Index (ß = 0.4, p< 0.02, and TE-Ea (ß = 0.5, p = 0.02 were showed as independent predictors of LVEDP (R2 = 49%. "n"nConclusion: Although we observed a moderate correlation between Doppler measurements and LVEDP in patients with severe MS, more similar studies are required.

  3. Medial arterial calcification, calcific aortic stenosis and mitral annular calcification in a diabetic patient with severe autonomic neuropathy.

    Cronin, C C


    Medial arterial calcification (Monckeberg\\'s arteriosclerosis) is well described in diabetic patients with autonomic neuropathy. There is also a high prevalence of diabetes mellitus among subjects with calcific aortic stenosis and mitral annular calcification. We describe a diabetic patient with autonomic neuropathy and extensive medial arterial calcification who also had calcification of the aortic valve and of the mitral valve annulus. We propose that autonomic neuropathy may play a role in calcification of these structures at the base of the heart.

    Guadalajara, J F; Laplaza, I; Torres Tono, A; Vera Delgado, A; Gual Juliá, J M; Huerta, D


    In this retrospective study of 43 patients of the National Institute of Cardiology of Mexico, 20 to 35 years after the first attack of rheumatic carditis shows that the prognosis of the heart valve disease is directly influenced by the number of attacks of rheumatic fever. In fact, when patients had only one rheumatic attack the secuelae was mild mitral regurgitation (19%), without hemodynamic significance, with less proportion of mitral stenosis (15%), or aortic regurgitation (7.6%), less plurivalvular lesions (16%), or required heart surgery (15%). In the other hand, when the patients suffered three rheumatic attacks had more proportion of mitral stenosis (33%), aortic regurgitation (41%), pluryvalvular lesions (38%) and required more heart (50%). We conclude that prophylactic treatment is important in patients with chronic rheumatic heart disease.

    Langerveld, Jorina; Valocik, Gabriel; Plokker, H W Thijs; Ernst, Sjef M P G; Mannaerts, Herman F J; Kelder, Johannes C; Kamp, Otto; Jaarsma, Wybren


    The objective of this study was to validate the additional value of 3-dimensional (3D) transesophageal echocardiography (TEE) for patients with mitral valve stenosis undergoing percutaneous mitral balloon valvotomy (PTMV). Therefore, in a series of 21 patients with severe mitral valve stenosis selected for PTMV, 3D TEE was performed before and after PTMV. The mitral valve area was assessed by planimetry pre- and post-PTMV; the mitral valve volume was assessed and attention was paid to the amount of fusion of the commissures. These results were compared with findings by 2-dimensional transthoracic echocardiography using pressure half-time method for assessment of mitral valve area, and were analyzed for the prediction of successful outcome. Pre-PTMV the mitral valve area assessed by 3D TEE was 1.0 +/- 0.3 cm(2) vs 1.2 +/- 0.4 cm(2) assessed by 2-dimensional transthoracic echocardiography (P =.03) and post-PTMV it was 1.8 +/- 0.5 cm(2) vs 1.9 +/- 0.6 cm(2) (not significant), respectively. The mitral valve volume could be assessed by 3D TEE (mean 2.4 +/- 2.5 cm(3)) and was inversely correlated to a successful PTMV procedure (P <.001). The 3D TEE method enabled a better description of the mitral valvular anatomy, especially post-PTMV. We conclude that 3D TEE will have additional value over 2-dimensional echocardiography in this group of patients, for selection of patients pre-PTMV, and for analyzing pathology of the mitral valve afterward.

  7. Double Valve Replacement (Mitral and Aortic for Rheumatic Heart Disease: A 20-year experience with 300 patients.

    Prashant Mishra


    Full Text Available Introduction: Rheumatic heart disease still remains one of the leading causes of congestive heart failure and death owing to valvular pathologies, in developing countries. Valve replacement still remains the treatment of choice in such patients.The aim of this study wasto analyze the postoperative outcome of  double valve replacement (Mitral and Aortic in patients of rheumatic heart disease. Materials and Methods: Between 1988 and 2008, 300 patients of rheumatic heart disease underwent double (Mitral and Aortic valve replacement with Starr Edwards valve or St Jude mechanical valve prosthesis were implanted. These patients were studied retrospectively for preoperative data and postoperative outcome including causes of early and late deaths and the data was analyzed statistically. Results: The 30-day hospital death rate was 11.3% andlate death occurred in 11.6%. Anticoagulant regimen was followed to maintain the target pro-thrombin time at 1.5 times the control value. The actuarial survival (exclusive of hospital mortality was 92.4%, 84.6%, and 84.4%, per year at 5, 10, and 20 years, respectively Conclusions: In view of the acknowledged advantageof superior durability, increased thromboresistance in our patient population, and its cost effectiveness the Starr-Edwards ball valve or St. Jude valve is the mechanical prosthesis of choice for advanced combined valvular disease. The low-intensity anticoagulant regimen has offered suffcient protection against thromboembolism as well as hemorrhage.

  8. A ventriculotomia apical esquerda para tratamento cirúrgico da estenose mitral congênita The surgical treatment of congenital mitral stenosis through a left ventriculotomy

    Miguel Barbero-Marcial


    Full Text Available Entre junho de 1987 e outubro de 1990, nove pacientes consecutivos, portadores de estenose mitral congênita (EMC foram submetidos a correção cirúrgica. Sete tinham valva mitral em paráquedas e dois, outras formas complexas de estenoses. Em todos, a via de abordagem foi a ventriculotomia apical esquerda, sendo dividido, primeiramente, o músculo papilar; depois, as cordas e, finalmente, as cúspides. As lesões associadas foram corrigidas prévia ou simultaneamente. Todos os pacientes tiveram boa evolução imediata. Houve um óbito tardio não relacionado. O estudo ecocardiográfico seriado pós-operatório mostrou adequada função ventricular esquerda. Conclui-se que esta via é de escolha para tratar lesões estenóticas congênitas complexas da valva mitral.From June 1987 to October 1990, nine patients with congenital mitral stenosis (CMS underwent surgical correction through an apical left ventriculotomy. Seven patients had parachute mitral valve and two had other forms of CMS. The surgical treatment of the mitral valve apparatus starts from below: first the papillary muscle is split and the cordae are divided and fenestrated. Then, the commissurotomies were performed through the ventricles aspect of the mitral valve. Associated anomalies were corrected simultaneously. There was no in-hospital death and only one late death (nonrelated. The echocardiography showed non significant residual stenosis and normal global function of the left ventricle. In conclusion, the appical left ventriculotomy is a good approach for treatment of CMS.

  9. Mitral annular calcification in patients undergoing aortic valve replacement for aortic valve stenosis.

    Takami, Yoshiyuki; Tajima, Kazuyoshi


    Limited data exis t on clinical relevance of aortic valve stenosis (AVS) and mitral annular calcification (MAC), although with similar pathophysiologic basis. We sought to reveal the prevalence of MAC and its clinical features in the patients undergoing aortic valve replacement (AVR) for AVS. We reviewed 106 consecutive patients who underwent isolated AVR from 2004 to 2010. Before AVR, CT scans were performed to identify MAC, whose severity was graded on a scale of 0-4, with grade 0 denoting no MAC and grade 4 indicating severe MAC. Echocardiography was performed before AVR and at follow-up over 2 years after AVR. MAC was identified in 56 patients with grade 1 (30 %), 2 (39 %), 3 (18 %), and 4 (13 %), respectively. Patients with MAC presented older age (72 ± 8 versus 66 ± 11 years), higher rate of dialysis-dependent renal failure (43 versus 4 %), and less frequency of bicuspid aortic valve (9 versus 36 %), when compared to those without MAC. No significant differences were seen in short- and mid-term mortality after AVR between the groups. In patients with MAC, progression of neither mitral regurgitation nor stenosis was observed at follow-up of 53 ± 23 months for 102 survivors, although the transmitral flow velocities were higher than in those without MAC. In conclusion, MAC represented 53 % of the patients undergoing isolated AVR for AVS, usually appeared in dialysis-dependent elder patients with tricuspid AVS. MAC does not affect adversely upon the survival, without progression of mitral valve disease, at least within 2 years after AVR.

    Robotic surgical techniques allow surgeons to perform mitral valve surgery. This procedure has gained acceptance, particularly for mitral valve repair in degenerative mitral disease. However, mitral repair may not always be possible, especially in severely calcified mitral valve of rheumatic origin. This study demonstrates the basic concepts and technique of robotic mitral valve replacement for valve pathologies that are not suitable for repair.

  13. A novel echocardiography formula for calculating predicted pulmonary vascular resistance in patients with mitral stenosis

    Amiliana M. Soesanto


    Full Text Available Background: Pulmonary vascular resistance (PVR plays an important role in the natural history, prognosis, and outcome after valve intervention in patients with mitral stenosis (MS. The existing formula to estimate PVR by means of echocardiography is not readily applicable in the MS patient subset because it does not specifically calculate the risk of PVR in MS. The aim of this study was to find a new echocardiography formula to estimate PVR in MS.Methods: This diagnostic study was conducted in 2 stages. In the first stage, 58 consecutive subjects with MS were studied to find some model formulas for estimating PVR by multiple regression. Eight echo parameters were analyzed to seek their correlation with the invasive PVR value as a gold standard. The formula that had the best correlation and was easiest to use would be selected. In the second stage, those model formulas were validated by applying them to a further 34 consecutive MS subjects.Results: Four formulas which gave a discriminator coefficient of r2 0.62–0.68 were derived.  The best model formula was proposed for further application.  The new selected formula PVR=-7.465+3.566 TRvmax –(0.23 TVs’+6.799 (RV-MPI showed good correlation (r=0.71, p<0.001 to the invasive PVR value, with good reliability. TRvmax is maximal velocity of tricuspid regurgitation, TVs’ is systolic velocity of tricuspid annulus, and RV-MPI is right ventricle index myocardial performance. ROC curve showed that the cut off point 7.2 has good sensitivity and specificity (90% and 88%, respectively to predict PVR 7 WU.Conclusion: This study has shown that a novel echocardiography formula can estimate PVR with good correlation and reliability in subjects with mitral stenosis.

    Prolonged left atrial electromechanical conduction time is related with atrial electrical remodeling, and is predictive of the development of atrial fibrillation. The aim of our study was to examine whether left atrial electromechanical conduction time (EMT) and left atrial strain as measured by speckle tracking echocardiography (STE) are predictors for the development of atrial fibrillation (AF) in patients with mitral stenosis (MS) at 5-year follow-up. A total of 81 patients (61% females; mean age 38.1 ± 12.1 years) with mild or moderate MS of rheumatic origin according to ACC/AHA guidelines who were in sinus rhythm, and were asymptomatic or have NYHA class 1 symptom were included in the study. AF was searched by 12-lead electrocardiograms or 24-h Holter recordings during follow-up period. Atrial electromechanical conduction time (EMT), peak atrial longitudinal strain (PALS) and peak atrial contraction strain (PACS) were measured by STE. EMTs was defined as the interval between the onset of P-wave to the peak late diastolic longitudinal strain in the basal lateral and septal wall. During the follow-up period of 5 years (mean follow-up duration, 48.2 ± 13.3 months), 30 patients (37%) developed AF on standard 12-lead ECG or at their 24-h Holter recording. At follow-up, patients who developed AF were older than patients without AF (42.4 ± 11.3 vs. 35.6 ± 11.9, p = 0.014). Mitral valve area (MVA) (1.39 ± 0.14 vs. 1.48 ± 0.18, p = 0.03), PALS (13.4 ± 4.6 vs. 19 ± 5.2, p Speckle tracking echocardiography is a basic and easily-implemented method based on left atrial parameters which may be helpful for early detection of atrial fibrillation in patients with mitral stenosis.

  15. Failure of oral penicillin as secondary prophylaxis for rheumatic heart disease: a lesson from a low-prevalence rheumatic fever region.

    McGlacken-Byrne, S M; Parry, H M; Currie, P F; Wilson, N J


    Our patient is an 18-year-old Caucasian woman from the UK who developed severe mitral stenosis on a history of childhood acute rheumatic fever (ARF) and rheumatic heart disease (RHD). She had been reporting of her oral penicillin secondary prophylaxis regimen since diagnosis. At the age of 15 years, a new murmur was discovered during routine cardiac follow-up. An echocardiogram confirmed moderate-severe mitral stenosis. One year later, her exercise tolerance significantly deteriorated and she subsequently underwent balloon valvuloplasty of her mitral valve to good effect. Our case emphasises the evidence base supporting the use of monthly intramuscular penicillin injection to prevent ARF recurrence and RHD progression; it also emphasises the reduced efficacy of oral penicillin prophylaxis in this context. It particularly resonates with regions of low rheumatic fever endemicity. The long-term cardiac sequelae of ARF can be devastating; prescribing the most effective secondary prophylaxis regimen is essential.

  16. MRI planimetry for diagnosis and follow-up of valve area in mitral stenosis treated with valvuloplasty

    Djavidani, B.; Lipke, C.; Nitz, W.; Feuerbach, S. [Inst. fuer Roentgendiagnostik, Universitaetsklinikum Regensburg (Germany); Debl, K.; Buchner, S.; Riegger, G.; Luchner, A. [Klinik und Poliklinik fuer Innere Medizin II, Universitaetsklinikum Regensburg (Germany)


    Purpose: we sought to determine whether noninvasive planimetry by magnetic resonance imaging (MRI) is suitably sensitive and reliable for visualizing the mitral valve area (MVA) and for detecting increases in the MVA after percutaneous balloon mitral valvuloplasty (PBMV). Materials and methods: in 8 patients with mitral valve stenosis, planimetry of the MVA was performed before and after PBMV with a 1.5 T MR scanner using a breath-hold balanced gradient echo sequence (true FISP). The data was compared to the echocardiographically determined MVA (ECHO-MVA) as well as to the invasively calculated MVA by the Gorlin formula at catheterization (CATH-MVA). Results: PBMV was associated with an increase of 0.79 {+-} 0.30 cm{sup 2} in the MVA ({delta} MRI-MVA). The correlation between {delta} MRI-MVA and {delta} CATH-MVA was 0.92 (p < 0.03) and that between {delta} MRI-MVA and {delta} ECHO-MVA was 0.90 (p < 0.04). The overall correlation between MRI-MVA and CATH-MVA was 0.95 (p < 0.0001) and that between MRI-MVA and ECHO-MVA was 0.98 (p < 0.0001). MRI-MVA slightly overestimated CATH-MVA by 8.0% (1.64 {+-} 0.45 vs. 1.51 {+-} 0.49 cm{sup 2}, p < 0.01) and ECHO-MVA by 1.8% (1.64 {+-} 0.45 vs. 1.61 {+-} 0.43 cm{sup 2}, n.s.). Conclusion: magnetic resonance planimetry of the mitral valve orifice is a sensitive and reliable method for the noninvasive quantification of mitral stenosis and visualization of small relative changes in the MVA. This new method is therefore capable of diagnosing as well as following the course of mitral stenosis. It must be taken into consideration that planimetry by MRI slightly overestimates the MVA as compared to cardiac catheterization. (orig.)

    Full Text Available Rheumatic fever (RF and rheumatic heart disease (RHD have decreased in prevalence in the advanced industrialized nation. In the developing world, RF and RHD although less prevalent than they were 30 to 50 years ago, are still a major health problem. Poor socio-economic standards and difficulty of reaching proper primary health care facilities are the main causes of the still relatively high prevalence. This article will discuss in brief the epidemiology of group A beta hemolytic streptococci (GAS and RF/RHD as well as their global burden. The gloomy past of RF/RHD will hopefully give way to the promising future we all strive to achieve through better social standards, sanitation and hygiene, and availability of better health care for all.

  18. Comparative study of heart rate responses to laryngoscopic endotracheal intubation and to endotracheal intubation using intubating laryngeal mask airway under general anaesthesia in patients with pure mitral stenosis for closed mitral commissurotomy.

    Das, Soumi; Gupta, Sampa Dutta; Goswampi, Anupam; Kundu, Kanak Kanti


    The various drugs and methods studied in an attempt to curb the haemodynamic stress response associated with conventional laryngoscopic endotracheal intubation have not been found to be ompletely satisfactory. The rise in heart rate can be detrimental to patients with mitral stenosis. This study was aimed to compare the heart rate responses to endotracheal intubation using conventional laryngoscope and with the help of intubating laryngeal mask airway (ILMA) in patients with isolated mitral stenosis. Thirty-four adult patients of either sex, aged between 18 and 40 years with isolated mitral stenosis to undergo closed mitral commissurotomy were randomly allocated into two groups : Group A (n=17)- To be intubated using laryngoscopy. Group B (n=17)- To be intubated with the help of ILMA. The heart rate was recorded immediately preinduction, just prior to introducing the intubating device and postintubation every minute up to first 5 minutes. On applying statistical tests, it was found that the median heart rate values in group A at 2, 3, 4 and 5 minutes postintubation were significantly higher than in group B (pendotracheal intubation was associated with rise in heart rate, the rise was less with ILMA compared to laryngoscope. Hence, it can be concluded that use of ILMA may be a preferable device for endotracheal intubation laryngoscopy in patients with isolated mitral stenosis.

  1. Aortic coarctation associated with aortic valve stenosis and mitral regurgitation in an adult patient: a two-stage approach using a large-diameter stent graft.

    Novosel, Luka; Perkov, Dražen; Dobrota, Savko; Ćorić, Vedran; Štern Padovan, Ranka


    We report a case of a staged surgical and endovascular management in a 62-year-old woman with aortic coarctation associated with aortic valve stenosis and mitral regurgitation. The patient was admitted for severe aortic valve stenosis and mitral valve incompetence. During hospitalization and preoperative imaging, a previously undiagnosed aortic coarctation was discovered. The patient underwent a 2-stage approach that combined a Bentall procedure and mitral valve replacement in the first stage, followed by correction of the aortic coarctation by percutaneous placement of an Advanta V12 large-diameter stent graft (Atrium, Mijdrecht, The Netherlands) which to our knowledge has not been used in an adult patient with this combination of additional cardiac comorbidities. A staged approach combining surgical treatment first and endovascular placement of an Advanta V12 stent graft in the second stage can be effective and safe in adult patients with coarctation of the aorta and additional cardiac comorbidities.

  2. Successful resuscitation from two cardiac arrests in a female patient with critical aortic stenosis, severe mitral regurgitation and coronary artery disease

    Mijušković Dragan


    Full Text Available Introduction. The incidence of sudden cardiac death in patients with severe symptomatic aortic stenosis is up to 34% and resuscitation is described as highly unsuccessful. Case report. A 72-year-old female patient with severe aortic stenosis combined with severe mitral regurgitation and three-vessel coronary artery disease was successfully resuscitated following two in-hospital cardiac arrests. The first cardiac arrest occurred immediately after intraarterial injection of low osmolar iodinated agent during coronary angiography. Angiography revealed 90% occlusion of the proximal left main coronary artery and circumflex branch. The second arrest followed induction of anesthesia. Following successful open-chest resuscitation, aortic valve replacement, mitral valvuloplasty and three-vessel aortocoronary bypass were performed. Postoperative pericardial tamponade required surgical revision. The patient recovered completely. Conclusion. Decision to start resuscitation may be justified in selected patients with critical aortic stenosis, even though cardiopulmonary resuscitation in such cases is generally considered futile.

  3. Predisposing factors to development of mitral regurgitation and valve area

    Kazemi Khaledi A


    Full Text Available Background: Percutaneous Transeptal Mitral Commisurotomy (PTMC has been used in treating mitral stenosis with variable success, its main complication being mitral incompetence. There is a need to define the subgroup of the patients who benefit mostly from the procedure. Methods: We studied 110 patients (age 17 to 60 years; mean 33.2 with mitral stenosis. PTMC was performed though femoral vein. All patients underwent echocardiographic evaluation, both before and after the procedure. Clinical, hemodynamic and echocardiographic data were gathered and used to predict the outcome. Results: PTMC was successful in all 110 patients in alleviating the stenosis (mean transmitral gradient before procedure was 17.1 mmHg; after procedure 4.4 mmHg. There was no mortality or major complication other than occurrence of mitral regurgitation in 9 cases. In this group only one patient subsequently needed a mitral valve replacement operation. The following parameters were found to have a significant correlation with the success rate of PTMC: lower age, shorter duration of illness, functional class III and IV, larger EF slope, smaller EPSS, smaller amplitude of valve motion, limitation of the posterior leaflet motion and negative history for open commisurotomy. The incidence of mitral regurgitation after procedure was found to be correlated with: atrial fibrillation rhythm before PTMC, lower age, longer duration of illness, more frequent relapse of rheumatic fever, functional class III and IV, less EF slope, limitation of the valve motion, larger left atrium, calcification of posterior leaflet and subvalvular extension. Conclusions: Balloon Mitral Valvuloplasty is an effective and relatively safe procedure in the management of the mitral stenosis. With the proper selection of the patients with the favorable outcome parameters, the rate of complication can be reduced.

MÉTODOS: Oitenta e oito portadores de estenose mitral sintomáticos com anatomia favorável foram randomizados nos dois grupos. Todos os pacientes submeteram-se a avaliação clínica e Doppler ecocardiográfica antes, imediatamente após e 12 meses depois do procedimento. RESULTADOS: Gradiente médio mitral (mmHg diminuiu (pPURPOSE: To compare immediate and late (12 months follow up of clinical and Doppler echocardiographic results between percutaneous mitral balloon valvuloplasty and open commissurotomy in a prospective and randomized trial. METHODS: Eighty eight symptomatic patients with severe mitral stenosis and favorable anatomy were randomized in a prospective trial comparing the two procedures. All patients were submitted to clinical and Doppler echocardiographic evaluation before the procedures and immediate and twelve months thereafter. RESULTS: Mean mitral gradient (mmHg decreased from 12.2±5.8 to 5.80±2.7 (p<0.001 in commissurotomy group (CG and from 11.7±6.1 to 5.0±2.4 (p<0.001 in the balloon valvuloplasty group (VG. Mitral valve area (cm² increased from 0.98±0.21 to 2.52±0.46 in CG and from 1.05±0.25 to 2.18±0.40 in VG (p<0.001. In both groups there was a slight decrease in mitral valve area at 12 month follow-up. There was no death in either group. One patient in the VG had moderate mitral regurgitation and underwent surgery. At the 12 month follow-up, all patients in CG and 97.7% of patients in VG were in New York Heart Association functional class I or II. CONCLUSION: Both procedures were safe and showed similar immediate improvement in mitral gradient and functional class. Mitral valve area had a greater increase immediately after commissurotomy, however there was a significantly greater reduction in the CG after 12 months of follow-up, when compared to balloon valvuloplasty.

  5. Role of the MAPKs/TGF-β1/TRAF6 signaling pathway in atrial fibrosis of patients with chronic atrial fibrillation and rheumatic mitral valve disease.

    Zhang, Daoliang; Liu, Xu; Chen, Xiaoqing; Gu, Jun; Li, Feng; Zhang, Wei; Zheng, Yue


    Atrial remodeling is involved in atrial fibrillation (AF), and atrial fibrosis is an important marker of atrial remodeling. On the basis of our previous animal studies of the mitogen-activated protein kinases (MAPKs)/transforming growth factor β1 (TGF-β1)/tumor necrosis factor pathway in atrial fibrosis, we undertook investigation of this signaling pathway in atrial fibrosis of patients with chronic AF (CAF) and rheumatic mitral valve disease. Fifty-six rheumatic mitral valve disease patients were divided into CAF (course of AF >12 months) and sinus rhythm (SR) groups. Left atrial appendage tissue was collected during heart surgery, and pathological examination was done to evaluate atrial fibrosis. Protein and mRNA expression of TGF-β1, TRAF6 and connective tissue growth factor (CTGF) and protein expression of phosphorylated MAPKs and TGF-β-activated kinase 1 (TAK1) were measured. Histological examination revealed that the severity of atrial fibrosis in CAF patients was significantly higher, mRNA and protein expression of TGF-β1, TRAF6 and CTGF in CAF were significantly increased, and the protein expression of phosphorylated MAPKs and TAK1 was significantly increased in CAF compared to SR patients. The MAPKs/TGF-β1/TRAF6 signaling pathway is involved in atrial fibrosis of CAF patients, and TRAF6 may become a new target for the treatment of atrial fibrosis.

    Between 1953 and 1976 a total of 2527 mitral commissurotomies have been performed in the Clinic for Cardio-Vascular Surgery of the "Fundeni" Hospital. This group included cases with pure mitral stenosis (predominantly following rheumatic disease), but also cases of mitral stenosis associated with other cardiac lesions in which the major hemodynamic element was the mitral obstruction. Criteria are discussed for surgery, the preoperative preparation of the patient, incidents, accidents and complications, as well as technical difficulties of the digital and/or instrumental mitral commissurotomies on closed heart, either carried out for the first time in the respective patient, or as iterative intervention. Comparing the results in relation with the functional stage of the disease (62.5% of the patients were classified in the III-IV evolutive degree, according to the NIHA classification), pulmonary hypertension (61.6% of the patients had medium or severe pulmonary hypertension), associated lesions (present in 17% of the cases--mitral failure predominated, together with tricuspid or aortic failures), it is appreciated that the technique of mitral commissurotomy on closed heart is an useful therapeutic method (88.6% very good and good results, a global death rate of 3.9%) that can be applied in a large category of patients, although there is a trend toward open-heart surgery, with all medico-economical major implications.

    Taniyasu, N; Kou, E; Hiramatsu, T; Yokoyama, S; Takenaka, A; Ikawa, O


    The patient was a 48-year-old woman with aortic stenosis and regurgitation and mitral stenosis. Preoperative cardiac catheterization revealed LV-Ao pressure gradient of 30 mmHg and regurgitation of Sellers III. The aortic annulus was measured less than 19 mm. As operative findings, the aortic annulus seemed to be too small to be replaced with 19 mm prosthetic valve. Aortic valvuloplasty (AVP) with rasping technique was performed for the aortic valve and valve replacement was carried out for the mitral valve. After aortic declamping and occurring her beat, the transesophageal echocardiographic evaluation for AVP was effective. Postoperative course was uneventful. Postoperative cardiac catheterization have shown decreased transvalvular pressure gradient up to 10 mmHg and aortic regurgitation of Sellers I.

    Fukunaga, Naoto; Matsuo, Takehiko; Saji, Yoshiaki; Imai, Yukihiro; Koyama, Tadaaki


    A 42-year-old woman presented with a 6-month history of palpitations and progressive dyspnea on exertion. She had undergone aortic and mitral valve repair using glutaraldehyde-treated autologous pericardium for active infective endocarditis 5 years prior. Transthoracic echocardiography showed mitral valve stenosis with limited movement of the anterior leaflet. At redo surgery, severe calcification of the glutaraldehyde-treated pericardial patch on the anterior mitral leaflet was observed. Double valve replacement was performed with pulmonary vein isolation. Pathologic examination showed calcification of the glutaraldehyde-treated autologous pericardium. The patient was discharged on postoperative day 11 with oral anticoagulant therapy. Copyright © 2015 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

    ística. CONCLUSÕES: Concluímos que o resultado pós-operatório imediato e a médio prazo (3,4 anos da reconstrução mitral por insuficiência mitral pura foi satisfatório nos dois grupos. A evolução dos pacientes com doença cardíaca reumática no período de seguimento foi comparável àqueles com degeneração mixomatosa quanto a mortalidade imediata e tardia, endocardite, acidente tromboembólico e sangramento associado a anticoagulante.RACIONALE: Most surgical intervention on the mitral valve in Brazil are due to rheumatic cardiac disease (RCD. Some advantages of the mitral valve repair over replacement are lower operative and late mortality, maintenance of geometry and left ventricular function. Nevertheless, the evolution of the RCD can jeopardize the late results of mitral reconstruction. OBJECTIVE: The objective of this study is to compare the results of mitral valve repair for isolated regurgitation in our patients with RCD and myxomatous degeneration (MD. MATERIAL AND METHODS: Charts from patients with RCD (n = 11, and MD (n = 9 submitted to mitral repair between July 1992 and August 1999 were reviewed. Twenty six mitral procedures were performed on patients with MD, and 31 on those with RCD. Bovine pericardial ring was used for anuloplasty on 18 patients, and rigid (Carpentier ring on 2 (one in each group. The techniques were quadrangular ressection (n = 13, trench shortening (n = 5, comissurotomy (n = 4, leaflet extention (n = 3, chordal transposition (n = 3, chordal replacement (n = 2, papilotomy (n = 2, chordal plication (n = 1, and folding plasty (n = 1. RESULTS: Mean follow-up was 41.5 months (6 to 96 months, and one patient was lost. There were no hospital or late deaths. One patient with RCD were reoperated for disease evolution. One patient was treated concervatively for endocaditis 3 months after surgery. The difference on left ventricular diameter, both systolic and diastolic, did not reach statistical significance (p = 0.20; p = 0.17, respectively

  11. The Effect of Valsartan on Heart Rate Variability and Heart Rate Recovery in Patients with Mild to Moderate Mitral Stenosis

    Ali Metin Esen


    Full Text Available Summary: Atrial fibrillation (AF is known to be one of the most important complications of mitral stenosis (MS. It has been reported that autonomic nervous system (ANS had an effect on AF development, heart rate variability (HRV and heart rate recovery (HRR were under the control of ANS, and their disorders were present in MS. We studied the effect of Valsartan on HRV and HRT, and thus its effect on ANS. Methods: Eleven patients (39±8 years, 10 females with mild to moderate MS were included in the study. Sixteen volunteers (38±8 years, 14 females matched for age and sex were selected for control group. All subjects underwent transthoracic echocardiography (TTE, symptom-limited treadmill test and 24 hour Holter monitorization.The patients were administered 160 mg of Valsartan daily for 14 weeks. TTE, treadmill test and Holter monitorization were repeated at the end of treatment period. In Holter monitorization, the time and frequency domain analysis of HRV and in exercise test, HRR at first and third minutes (HRR1 and HRR3 were examined. Results: Before Valsartan treatment, no significant difference was found in HRR and HRV parameters between the two groups. Systolic and diastolic blood pressure, and also HRR1values were significantly decreased after treatment of Valsartan (117±6 vs. 107±4 mmHg p<0.002, 76±6 vs. 69±9 mmHg p<0.044, 44±14 vs. 33±12 p< 0.014, respectively, while the exercise time was significantly increased (786±114 vs. 846±95 sn p< 0.044. In Holter analysis neither time nor frequency domain of HRV parameters showed a meaningful change. Conclusion: In moderate MS, treatment with Valsartan improved the effort capacity, while autonomic function parameters have been defined on the base of HRV and HRR were not significantly different.

  14. Antiphospholipid Syndrome and Libman-Sacks Endocarditis in a Bioprosthetic Mitral Valve.

    Sladek, Eric H; Accola, Kevin D


    This report describes one the first cases of antiphospholipid syndrome and Libman-Sacks endocarditis in a bioprosthetic valve. A redo mitral valve replacement was carried out owing to early deterioration of the prior valve. Initially it was considered secondary to rheumatic heart disease; however, pathology analysis and autoimmune workup revealed antiphospholipid syndrome with Libman-Sacks endocarditis. We believe certain populations with mitral valve stenosis may have an underlying antiphospholipid syndrome. As a result, there needs to be a lower threshold for identifying this disease.

  15. Rheumatic fever & rheumatic heart disease: the last 50 years.

    Kumar, R Krishna; Tandon, R


    Rheumatic fever (RF) and rheumatic heart disease (RHD) continue to be a major health hazard in most developing countries as well as sporadically in developed economies. Despite reservations about the utility, echocardiographic and Doppler (E&D) studies have identified a massive burden of RHD suggesting the inadequacy of the Jones' criteria updated by the American Heart Association in 1992. Subclinical carditis has been recognized by E&D in patients with acute RF without clinical carditis as well as by follow up of RHD patients presenting as isolated chorea or those without clinical evidence of carditis. Over the years, the medical management of RF has not changed. Paediatric and juvenile mitral stenosis (MS), upto the age of 12 and 20 yr respectively, severe enough to require operative treatement was documented. These negate the belief that patients of RHD become symptomatic ≥20 years after RF as well as the fact that congestive cardiac failure in childhood indicates active carditis and RF. Non-surgical balloon mitral valvotomy for MS has been initiated. Mitral and/or aortic valve replacement during active RF in patients not responding to medical treatment has been found to be life saving as well as confirming that congestive heart failure in acute RF is due to an acute haemodynamic overload. Pathogenesis as well as susceptibility to RF continue to be elusive. Prevention of RF morbidity depends on secondary prophylaxis which cannot reduce the burden of diseases. Primary prophylaxis is not feasible in the absence of a suitable vaccine. Attempts to design an antistreptococcal vaccine utilizing the M-protein has not succeeded in the last 40 years. Besides pathogenesis many other questions remain unanswered.

  18. Clinical studies on the distribution of the pulmonary blood flow at rest and with exercise in mitral stenosis in connection with the reversibility of the pulmonary vascular lesion

    Kohno, Tomio


    In order to determine the severity and reversibilty of pathologic changes in the pulmonary vascular bed in mitral stenosis (MS), a retrospective review was made of pulmonary perfusion scans obtained at rest and during exercise in a series of 60 subjects - 37 patients with MS, 8 with mitral regurgitation (MR), 7 with aortic regurgitation and stenosis (ARS), and 8 normal persons (N). As expressed by Q(U/L), an increased ratio of pulmonary blood flow in the upper part to that in the lower part of the lung was significantly associated with exercise in the MR and ARS groups, as well as the N group. In the MS group, Q(U/L) patterns associated with exercise fell into three categories: (I) an increase in Q(U/L) that was lower at rest than 1.1, (II) an increase in Q(U/L) that was higher at rest that 1.1, and (III) a decrease in Q(U/L). The MS group I had the worst preoperative parameters for cardiac and pulmonary function, followed by the group II and then the group III. For 23 patients receiving mitral valve replacement, postoperative parameters, including mean pulmonary arterial pressure, cardiac index, and pulmonary arterial resistance, were worse in the group II than the groups I and III. The results suggest that organic changes in the pulmonary vascular bed, as opposed to its reversible changes in the groups I and III, have occurred in the group II. Q(U/L) changes associated with exercise may be of value in determining the severity of MS. (Namekawa, K.).

    Sinha, Santosh Kumar; Jha, Mukesh Jitendra; Razi, Mahmadula; Chaturvedi, Vikash; Erappa, Yatish Besthenahalli; Singh, Shravan; Mishra, Vikas; Khanra, Dibbendhu; Singh, Karandeep


    BACKGROUND Coronary artery embolization is an exceedingly rare cause of myocardial infarction, but a few cases in association with prosthetic mechanical valves have been reported. We report a case of embolic myocardial infarction caused by a thrombus in the left atrium with deranged coagulation profile in a patient with critical mitral stenosis under warfarinization. CASE REPORT A 22-year-old woman was taken to the catheterization lab for early coronary intervention in lieu of non-ST elevation myocardial infarction. Electrocardiography showed T↓ in V1 to V4, and atrial fibrillation with controlled ventricular rate. Coronary angiography showed total occlusion of the mid-left anterior descending artery with thrombus. After upstream treatment with tirofiban, the apparent thrombus was dislodged distally while passing a BMW wire. No abnormalities were seen by intravascular ultrasound study. Echocardiography revealed critical mitral stenosis, and left atrial clot with mild left ventricular dysfunction. Coagulation profile revealed sub-therapeutic international normalized ratio levels. The sequential angiographic images, normal intravascular ultrasound study, and presence of atrial fibrillation are confirmatory of coronary embolism as the cause of myocardial infarction. Anticoagulation and treatment of acute coronary syndrome were initiated and she was referred for closed mitral valvulotomy. CONCLUSIONS Coronary artery thromboembolism as a nonatherosclerotic cause of acute coronary syndrome is rare. The treatment consists of aggressive anticoagulation, antiplatelet therapy, and interventional options, including simple wiring when possible. In this context, primary prevention in the form of patient education on optimal anticoagulation with oral vitamin K antagonist and medical advice about imminent thromboembolic risks are of extreme importance.

    LIU Pin-ming; FU Xiang-yang; L(U) Jun-hao; WU Qun; Yang Fu-qing


    Objective: To explore whether successful valvuloplasty increases mitral valve reserve capacity in patients with mitral stenosis. Methods: Thirty-eight patients with pure rheumatic mitral stenosis underwent isoproterenol stress echocardiography before and after successful percutaneous balloon valvuloplasty. The mitral valve area (by direct planimetry of two-dimensional echocardiography), mean transmitral pressure gradient (by continuous-wave Doppler echocardiography), and cardiac output (by M-mode echocardiography)were measured at rest and under isoproterenol infusion to achieve heart rate of different stages. Results :Between the measurements before and after valvuloplasty, significant differences were observed in the mitral valve area (0. 91±0.28 vs 1.87±0.23 cm2, P<0.01), mean transmitral pressure gradient (12.5±6.3 vs 3. 9±1.9 mmHg, P<0. 01) and cardiac output (3.93±1.44 vs 4. 73±1.01 L/min, P<O. 05) at rest. Before valvuloplasty, the mean transmitral pressure gradient increased significantly (P<0. 01) as heart rate increased, but there were no significant differences in the measurements of mitral valve area and cardiac output (both P>0. 05). In contrast, there was a significant increase after valvuloplasty in the mean transmitral pressure gradient (P<0. 01), but both mitral valve area and cardiac output further increased (both P<0. 01) as beart rate increased. Moreover, valvuloplasty decreased the mean transmitral pressure gradient at peak heart rate from 23.0 ±4. 5 to 7.75 ±2. 30 mmHg (P<0.01) under submaximal stress. Conclusion:Successful percutaneous balloon valvuloplasty soon causes a significant increase of mitral valve reserve capacity in patients with mitral stenosis, which is conspicuously manifested under condition of hemodynamic stress.Stress echocardiography provides a safe, feasible and non-invasive means of assessing the reserve capacity.

    Sixty years old male with severe rheumatic mitral stenosis (MS), presented with dyspnoea New York Heart Association (NHYA) class III to IV. Coronary angiogram revealed severe occlusive coronary artery disease in left anterior coronary artery (LAD). Percutaneous Transvenous Mitral Commissurotomy (PTMC) and Percutaneous Coronary Intervention (PCI) of Left Anterior Descurery (LAD) were done in same sitting. Both procedures were successful and ended without complication. After, half an hour while shifting to coronary care unit (CCU) patient developed cardiac tamponade, which was managed successfully. Patient was followed up for three month, he is doing well and recent echocardiogram showed mild mitral stenosis with normal left ventricular function. This case demonstrates the feasibility of the combined appliance on interventional techniques in selected patients as an alternative to cardiac surgery.

  2. A decision tree – based method for the differential diagnosis of Aortic Stenosis from Mitral Regurgitation using heart sounds

    Loukis Euripides N


    Full Text Available Abstract Background New technologies like echocardiography, color Doppler, CT, and MRI provide more direct and accurate evidence of heart disease than heart auscultation. However, these modalities are costly, large in size and operationally complex and therefore are not suitable for use in rural areas, in homecare and generally in primary healthcare set-ups. Furthermore the majority of internal medicine and cardiology training programs underestimate the value of cardiac auscultation and junior clinicians are not adequately trained in this field. Therefore efficient decision support systems would be very useful for supporting clinicians to make better heart sound diagnosis. In this study a rule-based method, based on decision trees, has been developed for differential diagnosis between "clear" Aortic Stenosis (AS and "clear" Mitral Regurgitation (MR using heart sounds. Methods For the purposes of our experiment we used a collection of 84 heart sound signals including 41 heart sound signals with "clear" AS systolic murmur and 43 with "clear" MR systolic murmur. Signals were initially preprocessed to detect 1st and 2nd heart sounds. Next a total of 100 features were determined for every heart sound signal and relevance to the differentiation between AS and MR was estimated. The performance of fully expanded decision tree classifiers and Pruned decision tree classifiers were studied based on various training and test datasets. Similarly, pruned decision tree classifiers were used to examine their differentiation capabilities. In order to build a generalized decision support system for heart sound diagnosis, we have divided the problem into sub problems, dealing with either one morphological characteristic of the heart-sound waveform or with difficult to distinguish cases. Results Relevance analysis on the different heart sound features demonstrated that the most relevant features are the frequency features and the morphological features that

    Mitral valve regurgitation (MR), present in up to 74% of the patients with severe aortic stenosis (AS), can be a negative prognostic factor when moderate or severe. The outcome of MR after percutaneous transcatheter aortic valve implantation (TAVI) and predictors associated with that outcome have not been well established in the literature. To assess the outcome of primary MR in patients submitted to TAVI and to identify associated factors. Observational study of patients with symptomatic severe AS submitted to TAVI from January 2009 to April 2015 at two specialized centers. Echocardiographic outcome was assessed with data collected before and 1 year after TAVI. Of the 91 patients with MR submitted to TAVI and followed up for at least 12 months, 67 (73.6%) had minimum/mild MR before the procedure and 24 (26.4%) had moderate/severe MR. Of those with minimum/mild MR, 62 (92.5%) had no change in the MR grade (p literatura.

    Full Text Available BACKGROUND Atrial fibrillation (AF, the most common sustained cardiac rhythm disturbance, commonly occurs with rheumatic heart disease, particularly mitral stenosis. Hemodynamic impairment and thromboembolic events result in significant morbidity& mortality. Left atrial (LA enlargement is one of the elements that evolve in the natural history of mitral stenosis. The objective of this study is to study the relation between echo cardio graphically determined left atrial size and atrial fibrillation in mitral valve disease (MVD. METHODOLOGY 50 Patients with rheumatic heart disease with mitral valve disease were studied using ECG and ECHO, excluding patients with congenital heart diseases, non-rheumatic mitral valve disease, essential hypertension, patients undergone PTMC or valvuloplasty or valve replacement, coronary artery diseases, patients on antiarrhythmic drugs, pregnant women. Left atrial dimensions measured by ECHO in patients of MVD and AF on ECG were compared with the left atrial dimension of patients in sinus rhythm. RESULTS In this study 42 patients had left atrial size >40 mm, 29(93.55% of them were in atrial fibrillation and only 13(68.42% were in sinus rhythm. Among 8 patients with left atrial size <40 mm, 2(6.45% were in atrial fibrillation and 06(31.58% were in sinus rhythm with p<0.02 which is significant. CONCLUSION Atrial fibrillation incidence was common when left atrial dimension was above 40 mm. There is a quantitative relation between left atrial size measured echocardiographically and the presence or absence of atrial fibrillation. These results may have therapeutic implication in that it may be possible with echocardiography, to identify patients in sinus rhythm, who are at high risk of developing atrial fibrillation. Prophylactic anticoagulation, antiarrhythmic therapy or both might be considered in management to prevent embolism.

    Sydney Correia Leão


    Full Text Available OBJECTIVES: Rheumatic fever is a highly prevalent disease in Brazil, and it poses a major public health problem. It is the leading cause of acquired heart disease in childhood and adolescence. The aim of this study was to evaluate the gene expression of ET-3 and its receptors, in replaced rheumatic mitral valves. METHODS: We studied the gene expression of endothelin-3 (ET-3 and its receptors, endothelin receptor A and endothelin receptor B (ETr-A and ETr-B, in the rheumatic mitral valves of 17 patients who underwent valve replacement surgery. The samples also underwent a histological analysis. RESULTS: Our data showed that almost all patients, regardless of individual characteristics such as gender or age, expressed the endothelin receptor genes, but did not express the genes for ET-3. In quantitative analysis, the ETr-A/GAPDH mean ratio was 33.04 ± 18.09%; while the ETr-B/GAPDH mean ratio was 114.58 ± 42.30%. Regarding histopathological individual features, the frequency of fibrosis is 100%, 88.23% of mononuclear infiltrate, 52.94% of neovascularization, 58.82% of calcification and absence of ossification. CONCLUSION: The presence of receptors ETr-A and ETr-B in rheumatic mitral valves suggests its interaction with the system of circulating endothelins, particularly ETr-B (known for acting in the removal of excess endothelin detected in a greater proportion, which could explain the lack of expression of endothelin in rheumatic mitral valve, process to be elucidated.OBJETIVOS: A febre reumática é uma doença altamente prevalente no Brasil, e representa um importante problema de saúde pública.

    Inoue, Takahiro; Hashimoto, Kazuhiro; Sakamoto, Yoshimasa; Nagahori, Ryuichi; Yoshitake, Michio; Matsumura, Yoko; Takagi, Tomomitsu; Kinami, Hiroo


    Left ventricular pseudoaneurysm is a rare, but potentially fatal, condition that generally occurs as a complication of myocardial infarction, infective endocarditis, or cardiac surgery. Surgical repair is the treatment of first choice because of the marked risk of rupture, but deteriorated hemodynamics and complicated procedures to treat the pseudoaneurysm may lead to a high mortality rate. We report a 62-year-old woman with a large left ventricular pseudoaneurysm after mitral valve replacement for rheumatic mitral valve stenosis. Surgical repair was not performed due to the patient's refusal, but her pseudoaneurysm resolved spontaneously by 2 years after mitral valve replacement. Spontaneous obliteration of a large left ventricular pseudoaneurysm is very rare in a patient on warfarin therapy. This case suggests that a left ventricular pseudoaneurysm with a narrow neck may resolve spontaneously in rare settings.

    Introduction Rheumatic mitral stenosis is the most common Valvular Heart Disease encountered during pregnancy. Balloon Mitral Valvuloplasty (BMV) is one of the treatment option available if the symptoms are refractory to the medical management and the valve anatomy is suitable for balloon dilatation. BMV with Inoue balloon is the most common technique being followed worldwide. Over the wire BMV is a modified technique using Joseph Mitral Valvuloplasty (JOMIVA) balloon catheter which is being followed in certain centres. Aim To assess the immediate post procedure outcome of over the wire BMV with JOMIVA balloon. Materials and Methods Clinical and echocardiographic parameters of pregnant women with significant mitral stenosis who underwent elective BMV with JOMIVA balloon in our institute from 2005 to 2015 were analysed retrospectively. Severity of breathlessness (New York Heart Association Functional Class), and duration of pregnancy was included in the analysis. Pre procedural echocardiographic parameters which included severity of mitral stenosis and Wilkin’s scoring were analysed. Clinical, haemodynamic and echocardiographic outcomes immediately after the procedure were analysed. Results Among the patients who underwent BMV in our Institute 38 were pregnant women. Twenty four patients (63%) were in New York Heart Association (NYHA) Class III. All of them were in sinus rhythm except two (5%) who had atrial fibrillation. Thirty four patients (89.5%) were in second trimester of pregnancy at the time of presentation and four (10.5%) were in third trimester. Echocardiographic analysis of the mitral valve showed that the mean Wilkin’s score was 7.3. Mean mitral valve area pre procedure was 0.8 cm2. Mean gradient across the valve was 18 mmHg. Ten patients (26.5%) had mild mitral regurgitation and none had more than mild mitral regurgitation. Thirty six patients had pulmonary hypertension as assessed by tricuspid regurgitation jet velocity. All of them underwent BMV

    The change in the level of NT-pro-BNP (N-terminal-pro-Brain Natriuretic Peptide) is now considered as a reflection of the hemodynamic alterations and its circulatory reductions reported early after successful PTMC (percutaneous transvenous mitral commissurotomy). The present study aims to assess the change in the level of NT-pro BNP following PTMC in patients with mitral stenosis and also to determine the association between circulatory NT-pro-BNP reduction and post-PTMC echocardiography parameters. Twenty five symptomatic consecutive patients with severe MS undergoing elective PTMC were prospectively enrolled. All patients underwent echocardiography before and also 24 to 48 hours after PTMC. Peripheral blood samples were taken for measurement of NT-pro-BNP before as well as 24 to 48 hours after PTMC. The patients were also classified in group with normal sinus rhythm or having atrial fibrillation (AF) based on their 12-lead electrocardiogram. It was shown a significant decrease in the parameters of PPG (Peak Pressure Gradient), MPG (Mean Pressure Gradient), PHT (Pressure Half Time), PAP (Pulmonary Arterial Pressure), LAV (Left Atrial Volume), and also a significant increase in MVA (Mitral Valve Area) RVS (Right Ventricular S velocity), and strains of lateral, septal, inferior and anterior walls of LA following PTMC. The mean LVEF remained unchanged after PTMC. The mean NT-pro-BNP before PTMC was 309.20 ± 17.97 pg/lit that significantly diminished after PTMC to 235.72 ± 22.46 pg/lit (p = 0.009). Among all echocardiography parameters, only MPG was positively associated with the change in NT-pro-BNP after PTMC. Comparing the change in echocardiography indices between the patients with normal rhythm and those with AF, lower change in PAP was shown in the group with AF. However, more change in the level of NT-pro-BNP after PTMC was shown in the patients with AF compared to those without this arrhythmia. PTMC procedure leads to reduce the level of NT-pro-BNP. The

Methods A total of 90 cases of patients with rheumatic heart disease admitted to our hospital from February 2013 to February 2015 were selected and randomly divided into two groups. The treatment group received mitral valve replacement with preservation of mitral apparatus, while the control group received mitral valve replacement without preservation of mitral apparatus. The clinical effects of two groups were compared. Results After treatment, the cardiac function classification of treatment group was significantly better than that of control group (P<0.05), the LVEDD and LVESD were significantly lower than those of control group (P<0.05), and the FS and EF were significantly higher than those of control group (P<0.05). Conclusions Mitral valve replacement with preservation of mitral apparatus for treatment of rheumatic heart disease can effectively improve the heart function of patients, and improve the diastolic, systolic, ejection capability of left ventricle after operation, so as to




    Full Text Available Context ( Back ground Acute Rheumatic fever and Rheumatic heart disease are the most common acquired childhood heart disease in India. It is well established that 2 D Echo cardiography is more sensitive in picking up minor degrees of valvular regurgitation than clinical examination . AIMS & OBJECTIVES: To study the clinical profile of “Rheumatic Fever and Rheumatic heart disease“ & correlate it with Echocardiographic fin dings in Children under 15 years age group presenting to a tertiary care hospital. MATERIALS AND METHODS OF STUDY: Thirty six cases of Acute Rheumatic fever, which includes eight cases of first attack and twenty eight cases of reactivation of Rheumatic fev er were studied over a period of two years in paediatric medical wards, King George Hospital, Visakhapatnam.

Further Echocardiography was proved to be more sensitive in detecting even trivial or mi ld aortic regurgitation and mitral or aortic stenosis.

  14. Detection of left atrial thrombus in patients with mitral stenosis and atrial fibrillation: retrospective comparison of two-phase computed tomography, transoesophageal echocardiography and surgical findings

    Choi, Bo Hwa; Ko, Sung Min [Konkuk University Medical Center, Konkuk University School of Medicine, Department of Radiology, Research Institute of Medical Science, Seoul (Korea, Republic of); Hwang, Hweung Kon [Konkuk University Medical Center, Konkuk University School of Medicine, Department of Cardiology, Seoul (Korea, Republic of); Song, Meong Gun; Shin, Je Kyoun [Konkuk University Medical Center, Konkuk University School of Medicine, Department of Thoracic surgery, Seoul (Korea, Republic of); Kang, Woon Seok; Kim, Tae-Yop [Konkuk University Medical Center, Konkuk University School of Medicine, Department of Anesthesiology, Seoul (Korea, Republic of)


    This retrospective study aims to assess the accuracy of two-phase computed tomography (CT) and transoesophageal echocardiography (TEE) for the detection of left atrial (LA) thrombus in patients with mitral stenosis (MS) and atrial fibrillation (AF), by using intraoperative findings as the reference standard. Preoperative two-phase CT and intraoperative TEE were performed in 106 patients with MS and AF. The ratio (LAA/AA{sub L}) of Hounsfield units (HU) in the LA appendage (LAA) to the ascending aorta (AA) was calculated on the late-phase CT image. LA echodense masses on TEE and LA filling defects on two-phase CT were observed in 29 and 39 patients, respectively. Thirty-five LA thrombi were identified at surgery in 27 patients. Compared with the intraoperative findings, per-patient sensitivity, specificity, positive and negative predictive values of two-phase CT were 100 %, 85 %, 69 % and 100 %, and those by using TEE were 93 %, 95 %, 86 % and 97 % in detecting LAA thrombus. After adopting the cut-off value of 0.5 for the LAA/AA{sub L} HU ratio, the specificity and positive predictive value of two-phase CT were increased to 96 % and 90 %, respectively. Two-phase CT with a cut-off value of LAA/AA{sub L} HU ratio of 0.5 provides high performance for the detection of LAA thrombus. (orig.)

    Abdulkadir Yıldız


    Full Text Available Objective: We sought to analyze short-term clinical, echocardiographic, and hemodynamic consequences of percutaneous mitral balloon valvuloplasty (PMBV in the treatment of rheumatic mitral stenosis (MS in our clinic. Methods: We retrospectively reviewed 53 patients (49 females, 5 males; mean age 38±11 years who underwent PMBV for moderate or severe MS between January 2010 and October 2014. Procedural success was defined as the reaching a mitral valve area (MVA >1.5 cm2 and absence of grade 3 mitral regurgitation. Results: We were able to perform PMBV in 48 of 53 patients (91% and all the procedures that were completed were successful. PMBV couldn’t be performed in 3 patients due to inability to pass the mitral valve, 1 patient due to membranous obstructive vena cava and 1 patient due inability to perform septostomi. Two patients who underwent successful PMBV became symptomatic after an average of 14 months follow-up and mitral valve replacement was performed due to moderate-to-severe MS. Patients were followed for an average of 13 ± 8 months and atrial fibrillation development or embolic complications were not observed. Conclusion: Percutaneous mitral balloon valvuloplasty procedure is a safe and effective treatment approach with high success and low complication rates in experienced centers.

    se asocian a la disfunción endotelial, con aumento de los niveles de endotelina-1 (ET-1 y consecuencias sobre la circulación pulmonar, muchas veces determinando la hipertensión pulmonar (HP. Mientras que, la presencia de ET-1 y sus receptores en la propia válvula mitral, promoviendo alteraciones vasculares pulmonares y aumentando la deformación valvar reumática, aún es un asunto no abordado en la literatura. OBJETIVO: Determinar, mediante técnicas moleculares, la expresión de los genes de la endotelina y de sus receptores en válvulas mitrales reumáticas. MÉTODOS: 27 pacientes sometidos a reemplazo valvular mitral tuvieron su tejido valvar analizado, a fin de determinar la presencia de genes de ET-1 y sus receptores A y B. Fueron hechos análisis histológico y molecular de las valvas (divididas en fragmentos M1, M2 y M3 y recogidos datos clínicos y epidemiológicos de los pacientes. Fueron divididos en tres grupos: valvopatía mitral, mitroaórtica y pacientes reoperados. RESULTADOS: El estudio mostró la manifestación del gen da ET-1 en 40,7% de los sujetos y de su receptor A en todas las muestras, con manifestación minoritaria del gen del receptor B (22,2%. CONCLUSIÓN: Todos los pacientes expresaron la presencia de gen del receptor A. No hubo diferencia estadística en cuanto a la gravedad de la enfermedad, expresada en clase funcional, y a los subgrupos estudiados (valvopatías mitrales, mitroaórticos y pacientes reoperados, o en cuanto a la expresión de los genes de la ET-1 y sus receptores entre los subgrupos estudiados (valvopatías mitrales, mitroaórticos y pacientes reoperados.BACKGROUND: Cardiopathies are high prevalence conditions.

    Widgren Veronica


    Full Text Available Abstract Background There is limited information about any association between the onset of atrial fibrillation (AF and the presence of valvular disease. Methods We retrospectively examined 940 patients in sinus rhythm, examined by echocardiography in 1996. During 11 years of follow-up, we assessed the incidence of AF and outcome defined as valvular surgery or death, in relation to baseline valvular function. AS (aortic stenosis severity at baseline examination was assessed using peak transaortic valve pressure gradient. Results In univariate analysis, the risk of developing AF was related to AS (significant AS versus no significant AS; hazard ratio (HR 3.73, 95% confidence interval (CI 2.39-5.61, p Conclusions AS, but not MR, was independently predictive of development of AF and combined valvular surgery or death. In patients with combined AS and MR, the grade of AS, more than the grade of MR, determined the risk of AF and combination of valvular surgery or death. Further studies using contemporary echocardiographic quantification of aortic stenosis are warranted to confirm these retrospective data based on peak transaortic valve pressure gradient.

  18. Doppler echocardiography imaging in detecting multi-valvular lesions: a clinical evaluation in children with acute rheumatic fever.

    Pushpa Shivaram

    Full Text Available RATIONALE: Doppler echocardiography has been demonstrated to be accurate in diagnosing valvular lesions in rheumatic heart disease (RHD when compared to clinical evaluation alone. OBJECTIVE: To perform Doppler echocardiography in children clinically diagnosed by the Jones criteria to have acute rheumatic fever (ARF, and to then compare the effectiveness of echo in detecting single/multi-valvular lesions with that of the initial clinical evaluation. METHODS AND RESULTS: We enrolled 93 children who were previously diagnosed with ARF by clinical examination. Presence of valvular lesions were enlisted, first by clinical auscultation, and then by performing Doppler echocardiography. We found that Doppler echocardiography was a sensitive technique, capable of detecting valvular lesions that were missed by clinical auscultation alone. Echocardiography of patients with carditis revealed mitral regurgitation to be the most common lesion present (53 patients, 56.98%, followed by aortic regurgitation in 21 patients (22.6%. The difference between clinical and echocardiographic diagnosis in ARF children with carditis was statistically significant for mitral regurgitation, aortic regurgitation and tricuspid regurgitation. Clinical auscultation alone revealed 4 cases of mitral stenosis, 39 mitral regurgitation, 14 aortic regurgitation, 9 tricuspid regurgitation; in contrast, echo revealed 5 cases of mitral stenosis, 53 mitral regurgitation, 21 aortic regurgitation, 18 tricuspid regurgitation. CONCLUSION: Doppler echocardiography is a more sensitive technique for detecting valvular lesions. In the setting of ARF, echo enables a 46.9% higher detection level of carditis, as compared to the clinical examination alone. Echo was very significant in detecting regurgitation lesions, especially for cases of tricuspid regurgitation in the setting of multivalvular involvement. The results of our study are in accordance with previous clinical studies, all of which clearly

    Objective To determine whether successful valvuloplasty causes an increase of mitral valve area reserve in patients with mitral stenosis, isoproterenol stress echocardiography was used to compare mitral valve area and hemodynamic changes between pre- and post- valvuloplasty under conditions of increased cardiac work. Methods Thirtyeight patients with pure rheumatic mitral stenosis who had received successful percutaneous balloon valvulo plasty underwent isoproterenol stress echocardiography pre- and post- valvuloplasty. Mitral valve area (by direct planimetry of two- dimensional echocardiography), mean transmitral pressure gradient (by continuous-wave Doppler echocardiography), and cardiac output (by M -mode echocardiography) were measured at rest and under isoproterenol stress to achieve heart rate of different stages. Results Mitral valve area (0. 91± 0. 28 to 1. 87±0.23cm2, P <0.01), mean transmitral pressure gradient ( 12.5 ± 6. 3 to 3.9 ± 1.9mmHg, P < 0.01 ) and cardiac output (3.93 ± 1.44to 4. 73 ± 1.01 L/min, P < 0.05) at rest between pre - and post -valvuloplasty were significantly different.Pre-valvuloplasty, as heart rate increased under stress, mean transmitral pressure gradient increased significantly ( P < 0.01 ), but there were no significant differences in the measurements of mitral valve area and cardiac output (both P > 0.05). In contrast, as heart rate increased post- valvuloplasty, there was a significant increase in mean transmitral pressure gradient (P < 0.01), but both mitral valve area and cardiac output further increased significantly (both P < 0. 01) . Moreover, valvuloplasty decreased mean transmitral pressure gradient at peak heart rate from 23.0 ± 4. 5 to 7.75 ± 2.30 mmHg ( P < 0.01 ) under submaximal stress. Conclusions Successful percu taneous balloon valvuloplasty soon causes a significant increase of mitral valve area reserve in patients with mitral stenosis, which is markedly manifested under conditions of

    Ejiofor JI


    Full Text Available Julius I Ejiofor, Lawrence Cohn,† Tsuyoshi Kaneko Division of Cardiac Surgery, Brigham and Women’s Hospital, Boston, MA, USA †Lawrence Cohn passed away on January 9, 2016 Abstract: Since the first mitral valvuloplasty in 1923, the technique of mitral valvuloplasty has matured over the years and now has become the first-line treatment, especially in patients with myxomatous mitral regurgitation (MR. We have highlighted some of the major problems that are encountered with the various etiologies of MR. We believe that repair is always the optimal surgical procedure for any of the above etiologies if it is consistent with a long-term result. However, replacement has shown to be a safer procedure in some instances such as severe functional MR or destructive endocarditis.

  2. Recurrent stuck mitral valve: eosinophilia an unusual pathology.

    Awasthy, Neeraj; Bhat, Yasser; Radhakrishnan, S; Sharma, Rajesh


    Eosinophilia is a very unusual and rare cause of thrombosis of prosthetic mitral valve. We report a 10-year-old male child of recurrent stuck prosthetic mitral valve. The child underwent mitral valve replacement for severe mitral regurgitation secondary to Rheumatic heart disease. He had recurrent prosthetic mitral valve thrombosis, despite desired INR levels. There was associated eosinophilia. The child was treated on the lines of tropical eosinophilia with oral prednisolone and diethylcarbamazine, the eosinophil count dropped significantly with no subsequent episode of stuck mitral valve. We discuss the management of recurrent stuck mitral valve and also eosinophilia as a causative factor for the same.

    Take, Akira; Matuzaki, Shigeru; Oki, Shinichi (Jichi Medical School, Minamikawachi, Tochigi (Japan)) (and others)


    Seventy patients with rheumatic valvular disease were evaluated with preoperative CT scanning. The correlation of the obtained CT images to the operative findings were examined. Left atrial thrombi were found in 24 cases at the operation. CT scan had detected thrombi in 19 cases (79.2%) and echocardiography in 15 (62.5%). CT failed to find them in 5 cases in which the left atrial thrombi were less than 3 g. Echocardiogram, however, failed to detect thrombi in 9 cases, the largest being 14 g. There were 15 cases with left atrial calcification, in which 10 cases had left atrial thrombi. Nine cases out of these 10 cases had rough left atrial surface after thrombectomy. Early postoperative CT of 10 with left atrial calcification showed recurrent left atrial thrombi in 4 (40%) cases. Mitral valve calcification was found in 42 cases during operation. CT scan was able to detect it in 40 (95.2%), while echocardiogram detected in 34 cases (81.0%) (p<0.05). All mitral valves with calcification required replacement. Out of 30 cases with non calcified mitral valves, 9 underwent OMC, and the other 21 underwent mitral valve replacement. Aortic valve calcification was found in 9 out of 11 cases of aortic stenosis. All has been diagnosed by CT scan. In conclusion, 1. in detecting the left atrial thrombi, CT scan was superior to echo-cardiography, and provided useful information for planning the operative procedure including atrial approach and valvular manipulation, 2. CT scan could detect calcification of left atrial wall which had high incidence of thrombus formation and rough left atrial surface, 3. CT scan could detect calcification of both mitral and aortic valve, and showed the severity of valvular structural changes. (author).

    Since the last decade, percutaneous balloon mitral valvuloplasty with Inoue catheter is considered the treatment of choice for selected patients (mobile valve, no calcification and minimal subvalvular disease) with rheumatic mitral stenosis. We present the seven-year follow-up experience of 456 patients treated with this technique in the catheter laboratory of the Cardiology Hospital in National Medical Center SXXI. It is a retrospective, transversal and observational study performed with data obtained from January 1994 and December 2000, with a follow-up of 58.5 +/- 26.6 months (range 12-96 mean 22). We achieve an initial success of 82.8%, improvement of initial mitral valve area from 0.9 +/- 0.1 to 1.8 +/- 0.3 cm2, with a gain area from 88 to 106% (p 90%. From these patients, 93.1% remained in NYHA-II or -I functional class and the incidence of restenosis decreased.

  6. Intrinsic Wave Propagation of Myocardial Stretch, A New Tool to Evaluate Myocardial Stiffness: A Pilot Study in Patients with Aortic Stenosis and Mitral Regurgitation.

    Pislaru, Cristina; Alashry, Mahmoud M; Thaden, Jeremy J; Pellikka, Patricia A; Enriquez-Sarano, Maurice; Pislaru, Sorin V


    Left ventricular (LV) filling following atrial contraction generates LV myocardial stretch that propagates from base to apex with a speed proportional to myocardial elasticity. The aim of this study was to test the hypothesis that intrinsic velocity propagation of myocardial stretch (iVP) would be altered in patients with valvular disease and chronic LV pressure overload or volume overload, which may adversely affect mechanical properties of the LV tissue. A second aim was to compare iVP with flow propagation velocity in the chamber. Sixty subjects were prospectively recruited: 20 with severe aortic stenosis (AS), 20 with severe degenerative mitral regurgitation (MR), and 20 normal control subjects. LV iVP was measured using ultrahigh-frame rate tissue Doppler (350-460 frames/sec) and flow propagation velocity by color flow M-mode imaging. Follow-up data (up to 2 years) were retrieved from medical records. iVP was highest in patients with AS (2.2 ± 0.7 m/sec), intermediate in those with MR (1.6 ± 0.5 m/sec), and lowest in control subjects (1.4 ± 0.2 m/sec; P  1.8 m/sec. Overall, iVP correlated with age, LV morphology, severity of aortic valve obstruction, and measures of LV preload and afterload. At follow-up, patients with high iVP had lower survival free of major adverse cardiac events (P = .002). Flow propagation velocity was similar between groups and correlated poorly with iVP (r = 0.26, P = .10). A significant number of patients with severe AS and severe MR had rapid transmission of myocardial stretch, indicating increased myocardial stiffness. This information was not conveyed by measurement of flow propagation. Larger studies are needed to investigate the clinical utility of this novel measurement.

  7. Postpartum Acute Pulmonary Oedema with Sub clinical Rheumatic Heart Disease.

    R, Padmaja; Gande, Sri Krishna Padma Challa Rao


    Acute dyspnea with pulmonary oedema in postpartum is uncommon but life-threatening event. Contributing factors for pulmonary oedema include, administration of tocolytics, underlying cardiac disease, iatrogenic fluid overload and preeclampsia acounting 0.08% of pregnancies. Pulmonary embolism, amniotic fluid embolism, pneumonia, aspiration and pulmonary oedema are some of the potentially devastating conditions that should be considered by the attending physician. Here, we report a case of postpartum acute pulmonary oedema referred to causality after an emergency caesarean section in a private hospital. No matter what the underlying pathology, prompt administration and appropriate resuscitation is always the first priority. Only after the patient has been stabilized attention must be turned to diagnosis and specific treatment. A diagnosis of severe Mitral Stenosis, probably of rheumatic origin was made after stabilizing the patient.

Methods The content of collagen of the valve was measured and the types of collagen were analyzed by SDS-polyacrylamide gel electrophoresis. Results In mitral valve of controls, the content of collagen in cordae tendon was higher than that in the leaf (P<0.01), and mitral valve had more collagen as compared with aortic valve (P<0.01). Type Ⅰ collagen was dominant in normal valve as compared with type Ⅲ. In RHD patients, the collagen content in mitral valve and aortic valve was much high than the controls (P<0.01). Both type Ⅰ and Ⅲcollagen increased markedly in RHD patients, and

  9. Chronic Atrial Fibrillation Ablation with Harmonic Scalpel during Mitral Valve Surgery

    Brick, Alexandre Visconti; Braile, Domingo M.


    Objective To evaluate surgical treatment of chronic atrial fibrillation with ultrasound in patients with mitral valve disease, considering preoperative clinical characteristics of patients undergoing surgical procedure and follow-up in the immediate postoperative period, in hospital and up to 60 months after discharge. Methods We studied 100 patients with chronic atrial fibrillation and mitral valve disease who underwent surgical treatment using ultrasound ablation. Patient data were reviewed by consulting the control reports, including signs and symptoms, underlying disease, functional class, hospital stay, surgical procedure time, ablation time, immediate complications, and complications at discharged and up to 60 months later. Actuarial curve (Kaplan-Meier) was used for the study of permanence without recurrence after 12, 24, 36, 48 and 60 months. Results 86% of the patients had rheumatic mitral valve disease, 14% had degeneration of the mitral valve, 40% had mitral regurgitation, and 36% had mitral stenosis. Main symptoms included palpitations related to tachycardia by chronic atrial fibrillation (70%), congestive heart failure (70%), and previous episodes of acute pulmonary edema (27%). Early results showed that 94% of the patients undergoing ultrasound ablation reversed the rate of chronic atrial fibrillation, 86% being in sinus rhythm and 8% in atrioventricular block. At hospital discharge, maintenance of sinus rhythm was observed in 86% of patients and there was recurrence of chronic atrial fibrillation in 8% of patients. At follow-up after 60 months, 83.8% of patients maintained the sinus rhythm. Conclusion Surgical treatment of chronic atrial fibrillation with ultrasound concomitant with mitral valve surgery is feasible and satisfactory, with maintenance of sinus rhythm in most patients (83.8%) after 60 months of follow-up.

  10. Sapien XT Transcatheter Mitral Valve Replacement Under Direct Vision in the Setting of Significant Mitral Annular Calcification.

    Murashita, Takashi; Suri, Rakesh M; Daly, Richard C


    Mitral valve replacement carries a high risk in patients with extensive mitral annular calcification. We report the case of a 71-year-old woman with severely calcified mitral valve stenosis and extensive annular calcification. We approached the mitral valve through a left atriotomy using cardiopulmonary bypass and cardiac arrest. We successfully deployed a 29-mm Sapien XT valve under direct visualization with satisfactory positioning. We further balloon-expanded the device to diminish the likelihood of periprosthetic regurgitation. Open mitral valve replacement with a transcatheter valve can be performed without the need for decalcification of the mitral annulus and is a good alternative to conventional mitral valve replacement.

  11. Role of two dimensional strain and strain rate imaging in assessment of left ventricular systolic function in patients with rheumatic mitral stenosis and normal ejection fraction

    Hany Younan


    Conclusion: Patients with MS and preserved EF% had lower 2D longitudinal LV systolic S and Sr compared to the control group. 2D longitudinal LV systolic S and Sr imaging appears to be useful in the detection of subclinical LV systolic dysfunction in patients with MS and preserved EF%.

    Full Text Available Background: Considering suggested formula in the references and PCWP measured by catheterism, in the present study the relation between pulmonary capillary wedge pressure (PCWP measured the flow velocity of mitral valve and mitral annulus motion through tissue doppler imaging is evaluated Methods: 52 cases of severe MS were admitted for Balloon Mitral Valvolotomy (BMV are included in this study. Mean age was 35±5 years consisting of 40 females and 12 males. Valve area, Pulmonary artery systolic pressure (PAP, E (Maximum Velocity of mitral valve at the beginning of diastole & Em (Maximum rate of mitral annular motion at the beginning of diastole which is recorded through septal or lateral wall annulus site velocity and left atrial (LA size were also measured by echocardiography and PCWP & PAP through catheterism. All patients had normal ejection fraction (EF and coronary arteries; there was no other valvular diseases and shunts. Results: There was a significant correlation between PAP in echocardiography and catheterism. Mean PAP was 53±19 mmHg in echocardiography and 53.9±17.8mmHg in catheterism. There wasn't any correlation between PCWP in echocardiography and catheterism (P=0.33 and also no relation between PCWP and mitral valve area (MVA or LA size (P=0.2. E/Em ratio increased in severe MS cases.Conclusion: E/Em ratio and suggested formula would overestimate the wedge pressure so echocardiography is not a reliable method for measuring PCWP in severe MS. Em velocity and E/Em ratio may be used for estimating MS severity.

  13. Persistent atrial fibrillation is associated with inability to recover atrial contractility after MAZE IV surgery in rheumatic disease.

    Tinetti, Matias; Costello, Ramiro; Cardenas, Cesar; Piazza, Antonio; Iglesias, Ricardo; Baranchuk, Adrian


    MAZE IV surgery is effective in restoring sinus rhythm (SR) and atrial contraction (AC) in patients with nonrheumatic persistent atrial fibrillation (AF). However, there is less information on its effectiveness to restore AC in patients with rheumatic disease. To assess the effectiveness of the MAZE IV surgery in restoring AC in patients with rheumatic disease and long persistent AF. Prospective, consecutive study in patients who underwent cardiovascular surgery and had long persistent AF in whom MAZE IV surgery was performed. The presence of AC was assessed by lateral mitral annulus tissue Doppler. A total of 75 patients were included. Mean age 60 years (±11.7); 27 men (36%). AF duration was 63 months (±34.1). Primary indication for surgery: rheumatic mitral stenosis 67 patients and mitral insufficiency eight patients. Mean left ventricular ejection fraction (LVEF) was 51.8% (±12.1) and mean left atrial area was 37 cm(2) (±10.3). After a mean follow-up of 28 months (±9.3), 69 patients remained alive and 59 were in SR. AC was detected in 37.3% (Group A) and absent in 62.7% (Group B). The mean difference between groups was the high prevalence of AF longer than 5 years in group B (P = 0.000001). There were no differences related to left atrial size, LVEF, and age. In patients with rheumatic disease, the absence of correlation between SR recovery and AC recovery post MAZE IV surgery is significant. A history of long persistent AF lasting more than 5 years was a strong predictor for the absence of AC. ©2012, The Authors. Journal compilation ©2012 Wiley Periodicals, Inc.

  14. A Rare Case of Mitral Valve Prolapse in Endomyocardial Fibrosis.

    Xavier, Joseph; Haranal, Maruti Yamanappa; Reddy, Shashidhar Ranga; Suryaprakash, Sharadaprasad


    Mitral valve prolapse in endomyocardial fibrosis (EMF) is an unusual entity. Literature search reveals only 1 report of mitral valve prolapse assosiated with EMF. A 32-year-old woman, of African origin, who presented with features of right heart failure, was diagnosed to have mitral valve prolapse of rheumatic origin with severe mitral regurgitation and severe pulmonary hypertension (PAH). Intraoperative findings lead to the diagnosis of EMF. We report this rare case of mitral valve prolapse in EMF, in a geographical area where rheumatic heart disease is endemic, to showcase how a rare manifestation of EMF can be misdiagnosed as that of rheumatic heart disease.

  15. Changes in peak left atrial longitudinal strain after percutaneous balloon mitral valvotomy and its long term impact on left atrial volumes in patients in sinus rhythm

    Mohamed Ismail Ahmed


    Full Text Available Background: The prognostic signi cance of left atrial (LA size on cardiovascular outcome is now well recognised in literature. Balloon mitral valvotomy (BMV can reduce complications and improve outcome in rheumatic patients. On long term follow up in rheumatic mitral stenosis patients after BMV, left atrial volumes were shown to decrease. Methods: This is a prospective study that enrolled 54 patients who undergone successful BMV. Longitudinal Left atrial function was evaluated by speckle tracking derived strain. Left atrial volumes were measured before valvotomy, after the procedure and after 12 months during follow-up. The e ect of transmitral pressure gradient drop after balloon mitral valvotomy on left atrial strain was studied. In addition the relation between post-procedural increase of LA strain and left atrial volumes after 12 months was also evaluated. Results: There is signi cant reduction of mean trans-mitral pressure gradient from 13.104 ± 4.694 to 4.067±1.502 mmHg and signi cant improvement of mitral valve area from 1.0217 ±0.1178 to 1.766 ± 0.2307cms2 after the procedure (P value < 0.001. The mean peak longitudinal left atrial strain was much improved after BMV from 19.80±9.66 % to 34.39±12.86%. This di erence was statistically highly signi cant. (P value was <0.0001. The percent improvement of left atrial longitudinal strain correlated signi cantly with mean trans-mitral pressure gradient drop. Also left atrial mean peak left atrial longitudinal strain correlated signi cantly with left atrial volumes reductions after 12 months. Conclusions: Successful BMV results in reduction of mean left atrial volumes after 12 months which is well correlated with PALS percent change after BMV.

  16. Mitral Valve Replacement After Failed Mitral Ring Insertion With or Without Leaflet/Chordal Repair for Pure Mitral Regurgitation.

    Roberts, William C; Moore, Meagan; Ko, Jong Mi; Hamman, Baron L


    Mitral repair operations for correction of pure mitral regurgitation (MR) are generally quite successful. Occasionally, however, the reparative procedure incompletely corrects the MR or the MR recurs. From March 1993 to January 2016, twenty nine patients had mitral valve replacement after the initial mitral repair operation, and observations in them were analyzed. All 29 patients at the repair operation had an annular ring inserted and later (1 year in 21) mitral valve replacement. The cause of the MR before the repair operation appears to have been prolapse in 16 patients (55%), secondary (functional) in 12 (41%) (ischemic in 5), and infective endocarditis which healed in 1 (3%). At the replacement operation the excised anterior mitral leaflet was thickened in all 29 patients. Some degree of stenosis appeared to have been present in 16 of the 29 patients before the replacement operation, although only 10 had an echocardiographic or hemodynamic recording of a transvalvular gradient; at least 11 patients had restricted motion of the posterior mitral leaflet; 10, ring dehiscence; 2, severe hemolysis; and 2, left ventricular outflow obstruction. In conclusion, there are multiple reasons for valve replacement after earlier mitral repair. Uniformly, at the time of the replacement, the mitral leaflets were thickened by fibrous tissue. Measurement of the area enclosed by the 360° rings and study of the excised leaflet suggest that the ring itself may have contributed to the leaflet scarring and development of some transmitral stenosis.

  17. Emergency mitral valve replacement for acute severe mitral regurgitation following balloon mitral valvotomy: Pathophysiology of hemodynamic collapse and peri-operative management issues

    Praveen Reddy Bayya


    Full Text Available Severe mitral regurgitation (MR following balloon mitral valvotomy (BMV needing emergent mitral valve replacement is a rare complication. The unrelieved mitral stenosis is compounded by severe MR leading to acute rise in pulmonary hypertension and right ventricular afterload, decreased coronary perfusion, ischemia and right ventricular failure. Associated septal shift and falling left ventricular preload leads to a vicious cycle of myocardial ischemia and hemodynamic collapse and needs to be addressed emergently before the onset of end organ damage. In this report, we describe the pathophysiology of hemodynamic collapse and peri-operative management issues in a case of mitral valve replacement for acute severe MR following BMV.

    Bastos Maria Dias de Azeredo


    Full Text Available OBJECTIVE: To evaluate the immediate results of percutaneous mechanical mitral commissurotomy. METHODS: Thirty patients underwent percutaneous mechanical mitral commissurotomy performed with a Cribier's metallic valvulotome from 8/11/99 to 2/4/00. Mean age was 30.7 years, and 73.3% were women. With regards to functional class, 63.3% were class III, and 36.7% were class IV. The echocardiographic score had a mean value of 7.5± 1.8. RESULTS: The mitral valve area increased from 0.97±0.15cm² to 2.16±0.50cm² (p>0.0001. The mean diastolic gradient decreased from 17.9±5.0mmHg to 3.2±1.4mmHg. The mean left atrial pressure decreased from 23.6±5.4mmHg to 8.6±3.1mmHg, (p>0.0001. Systolic pressure in the pulmonary artery decreased from 52.7±18.3mmHg to 32.2±7.4mmHg. Twenty-nine cases were successful. One patient developed severe mitral regurgitation. Interatrial septal defect was observed and one patient. One patient had cardiac tamponade due to left ventricular perforation. No deaths occurred. CONCLUSION: This method has proven to be safe and efficient in the treatment of rheumatic mitral stenosis. The potential advantage is that it can be used multiple times after sterilization, which decreases procedural costs significantly.

    Objective To explore the pathological role and mechanisms of matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) in mitral valve of patients with rheumatic heart disease (RHD).Methods Experimental group was composed of 16 samples of rheumatic mitral valves,while control group consisted of 7 normal mitral valves from adults who were died accidentally without cardiovascular diseases.Tissue samples were investigated by hematoxylin and eosin stain,reverse transcription polymerase chain reaction (RT-PCR),immunohistochemistry and transmission electron microscopy (TEM).Results Pathological figures and microstructures of rheumatic transformation in experimental group were showed dramatically,while the structures were basically normal in control group.The expression levels of MMP-2,13 and TIMP-1,2 mRNA were increased significantly in RHD group compared with control group (P<0.05).Conclusion The up-regulation of the expression of MMPs/TIMPs system may involved in the remodeling of extracellular matrix of mitral valve,and may be one of the important molecular mechanisms in its rheumatic pathologic developing process.%目的 探讨基质金属蛋白酶(MMPs)及其抑制剂(TIMPs)在风湿性心脏病(RHD)二尖瓣膜病理改变中的作用及其机制.方法 实验组为成人RHD患者二尖瓣16例,对照组为同期意外死亡的无心脏病变的成人二尖瓣7例.经HE染色及电镜观察两组形态学和超微结构变化,采用逆转录-聚合酶链反应(RT-PCR)和免疫组织化学染色(SABC法)测定MMP-2、MMP-13、TIMP-1及TIMP-2在二尖瓣组织的mRNA含量和蛋白表达.结果 实验组为风湿性病理改变,对照组结构基本正常.实验组MMP-2、13及TIMP-1、2的mRNA表达分别为0.96±0.27、0.93±0.38、0.87±0.32、0.94±0.37,较对照组均明显增加(P<0.05);其MMP-2、13及TIMP-1、2蛋白表达亦明显高于对照组.结论 RHD患者二尖瓣膜中MMPs/TIMPs表达增强,可能参与二尖瓣细胞外基质(ECM)的重

  5. Double orifice mitral valve: A case report

    Musić Ljilja


    Full Text Available Introduction. Double orifice mitrol valve (DOMV is a very rare congenital heart defect. Case report. We reported 20-year-old male referred to our center due to evaluation of his cardiologic status. He was operated on shortly after birth for a tracheoesophageal fistula. Accidentally, echocardiography examination at the age of 4 years revealed double orifice mitral valve (DOMV without the presence of mitral regurgitation, as well as mitral stenosis, with normal dimensions of all cardiac chambers. The patient was asymptomatic, even more he was a kick boxer. His physical finding was normal. Electrocardiography showed regular sinus rhythm, incomplete right bundle branch block. Transthoracic echocardiography (TTE examination revealed the normal size of the left atrial, mitral leaflets were slightly more redundant. The left and right heart chambers, aorta, tricuspid valve and pulmonary artery valve were normal. During TTE examination on a short axis view two asymmetric mitral orifices were seen as a double mitral orifice through which we registered normal flow, without regurgitation and mitral stenosis. Transesophageal echocardiography (TEE examination from the transgastric view at the level of mitral valve, showed 2 single asymmetric mitral orifices separated by fibrous tissue, mitral leaflet with a separate insertion of hordes for each orifice. Conclusion. The presented patient with DOMV is the only one recognized in our country. The case is interesting because during 16-year a follow-up period there were no functional changes despite the fact that he performed very demanded sport activities. This is very important because there is no information in the literature about that.

  6. A Review of Acute Rheumatic Fever and Rheumatic Heart Disease Research in Malaysia.

    Hung, L C; Nadia, R


    A total of 39 titles related to rheumatic fever or rheumatic heart disease in Malaysia were found with online literature search dating back to their inceptions and through 2014. Additional publications from conference journals were included. Nine papers were selected based on clinical relevance and future research implications. There were no population-based studies on the incidence or prevalence of ARF or RHD. In the 1980s, the incidence of admission due to ARF ranged from 2 to 21.1 per 100 000 paediatric admission per year. The burden of disease was significant in the adult population; 74.5% of patients with RHD were female, of which 77.1% were in the reproductive age group of 15-45 years old. Rheumatic mitral valve disease constituted almost half (46.7%) of all mitral valve repairs, ranging from 44.8 - 55.8 patients per year from 1997 - 2003. From 2010-2012, mitral valve interventions increased to 184 per year, of which 85.7% were mitral valve repair. In children with ARF, 25.4% - 41.7% had past history of rheumatic fever or RHD. In patients with rheumatic mitral valve disease undergoing surgical or medical interventions, only 6% reported history of ARF, none had history of GABHS pharyngitis or antibiotic prophylaxis. Only 44.7% of patients with RHD on follow-up were on intramuscular benzathine penicillin prophylaxis. Overall, there is scarcity of publications on ARF and RHD in Malaysia. Priority areas for research include determination of the incidence and prevalence of ARF and RHD, identification of high-risk populations, evaluation on the implementation and adherence of secondary preventive measures, identification of subclinical RHD especially amongst the high-risk population, and a surveillance system to monitor and evaluate preventive measures, disease progression and outcomes.

    Mario O Vrandecic


    sistólico e diastólico final, em avaliações ecocardiográficas seriadas CONCLUSÃO: As valvas mitrais porcinas sem suporte têm mostrado melhor performance hemodinâmica, com maior possibilidade de manutenção da função e do tamanho do ventrículo esquerdo. Embora este estudo tenha demonstrado uma curva de aprendizado bem definida relacionada a um novo substituto valvar e à técnica cirúrgica, estes fatores são superados com treino e aderência à técnica atualmente em uso.The concept of replacing diseased mitral valve with porcine mitral stentless valve allowed to address the "idiosyncrasy" of the left ventricular flow and contractility. From March 92 to December 95, 108 patients had their mitral valves replaced by stentless mitral valves. Their age varied from 11 to 65 years (mean 35.22 ± 14.98. There were 67 (62% females and 41 (38% males. The predominant ethiology was rheumatic heart disease 94 (87% cases, followed by a prosthetic dysfunction 6 (5.6% cases, myxomatous disease 5 (4.6% cases, infective endocarditis 2 (1.9% cases and ischemic lesion 1 (0.9% case, 26 (24.1% patients had mitral stenosis, 24 (22.2% mitral regurgitation and the remaining 58 (53.7% mixed lesions; 21.3% of the patients had previous open heart operations. The great majority of the operated patients (97.2% were in functional class III and IV (NYHA. Associated procedures were performed in 9.3% (10 of the cases. RESULTS: Hospital mortality occurred in 7 (6.5% patients non valved related with exception of one whom developed early endocarditis. Of the 101 remaining 3 required reoperations, in two due to valved size mismatch and 1 due to papillary muscle tear. Of the 98 remaining patients, 2 were lost to follow-up, 96 patients have been followed for 3.2 to 45 months. During the late follow-up there were six (6.25% deaths, of the 3 patients with late prosthetic endocarditis, 2 had their valves replaced with standard bioprosthesis, with one death. The third patient expired before

  8. Rheumatic Heart Disease and Myxomatous Degeneration: Differences and Similarities of Valve Damage Resulting from Autoimmune Reactions and Matrix Disorganization

    Martins, Carlo de Oliveira; Demarchi, Lea; Ferreira, Frederico Moraes; Pomerantzeff, Pablo Maria Alberto; Brandao, Carlos; Sampaio, Roney Orismar; Spina, Guilherme Sobreira; Kalil, Jorge; Cunha-Neto, Edecio


    Autoimmune inflammatory reactions leading to rheumatic fever (RF) and rheumatic heart disease (RHD) result from untreated Streptococcus pyogenes throat infections in individuals who exhibit genetic susceptibility. Immune effector mechanisms have been described that lead to heart tissue damage culminating in mitral and aortic valve dysfunctions. In myxomatous valve degeneration (MXD), the mitral valve is also damaged due to non-inflammatory mechanisms. Both diseases are characterized by structural valve disarray and a previous proteomic analysis of them has disclosed a distinct profile of matrix/structural proteins differentially expressed. Given their relevance in organizing valve tissue, we quantitatively evaluated the expression of vimentin, collagen VI, lumican, and vitronectin as well as performed immunohistochemical analysis of their distribution in valve tissue lesions of patients in both diseases. We identified abundant expression of two isoforms of vimentin (45 kDa, 42 kDa) with reduced expression of the full-size protein (54 kDa) in RHD valves. We also found increased vitronectin expression, reduced collagen VI expression and similar lumican expression between RHD and MXD valves. Immunohistochemical analysis indicated disrupted patterns of these proteins in myxomatous degeneration valves and disorganized distribution in rheumatic heart disease valves that correlated with clinical manifestations such as valve regurgitation or stenosis. Confocal microscopy analysis revealed a diverse pattern of distribution of collagen VI and lumican into RHD and MXD valves. Altogether, these results demonstrated distinct patterns of altered valve expression and tissue distribution/organization of structural/matrix proteins that play important pathophysiological roles in both valve diseases.

  9. Left-sided approach for mitral valve replacement in a case of dextrocardia with situs solitus.

    Kikon, Mhonchan; Kazmi, Aamir; Gupta, Anubhav; Grover, Vijay


    Mitral valve surgery in dextrocardia is technically challenging due to its anatomical malposition. Minor modifications are required in the surgical technique to counteract the problems during cannulation and exposure of the mitral valve. We report a case of a patient with dextrocardia, situs solitus, rheumatic heart disease, severe mitral regurgitation, moderate pulmonary artery hypertension, and severe left ventricular dysfunction who underwent mitral valve replacement using a two-stage right atrial cannulation with left-sided left atrial atriotomy, with the surgeon standing on the left side of the patient. Our approach for mitral valve surgery in this clinical setting is simple.

  10. Minimally Invasive Transaortic Mitral Decalcification During Aortic Valve Replacement.

    Totsugawa, Toshinori; Sakaguchi, Taichi; Hiraoka, Arudo; Matsushita, Hiroshi; Hirai, Yuki; Yoshitaka, Hidenori


    Mitral annular calcification accompanied by aortic stenosis is hazardous for both double-valve replacement and transcatheter aortic valve implantation. Less invasive mitral procedure is required in this condition, and minimally invasive approach may further reduce the operative risk in high-risk patients. Here, we report minimally invasive transaortic mitral decalcification during aortic valve replacement through minithoracotomy. We believe that this option is feasible in patients who are at prohibitive risk for double-valve replacement or transcatheter aortic valve implantation because of severe mitral annular calcification.

  11. Chimney technique for mitral valve replacement in children.

    González Rocafort, Álvaro; Aroca, Ángel; Polo, Luz; Rey, Juvenal; Villagrá, Fernando


    Severe mitral stenosis is unusual in children, but it represents an important challenge for surgeons because of the scarcity of solutions. Several mitral percutaneous and surgical valvuloplasties are performed repetitively to delay mitral valve replacement. Most of the time these procedures show discouraging results. When mitral valve replacement is performed, the annulus may not be large enough to fit a substitute. We present, to our best knowledge, a new technique to implant a large prosthesis in a small annulus without negatively affecting the opening of the leaflets.

    目的 通过对风湿性二尖瓣瓣膜病合并三尖瓣关闭不全的患者在置换二尖瓣的同时施行三维瓣膜成形环治疗三尖瓣关闭不全,初步探讨这一新术式的疗效.方法 选取风湿性二尖瓣瓣膜病合并三尖瓣关闭不全者18例(治疗组),在行二尖瓣置换术的同时施行三维瓣膜成形环治疗三尖瓣关闭不全.同期18例(对照组)患者行二尖瓣置换术的同时施行De Vega环缩术.比较两组术中手术情况及术后2周、术后6个月时心脏超声指标的变化.结果 两组患者均康复出院,术后2周和术后6个月复查超声显示右心房横径、右心室横径、三尖瓣反流程度均较术前明显改善,差异有统计学意义(P<0.05);而且治疗组优于对照组,差异有统计学意义(P<0.05).结论 三维瓣膜成形环治疗三尖瓣关闭不全远期效果满意.%Objective To study the therapeutic effect of three dimensional valve prosthetic ring treatment of tricuspid incompetence at the same time in the replacement of mitral valve in patients with rheumatic mitral valve disease combined with tricuspid incompetence.Methods Eighteen patients with rheumatic mitral valve disease combined with tricuspid incompetence were given three dimensional valve prosthetic ring treatment of tricuspid incompetence at the same time in the replacement of mitral valve as treatment group.The same period 18 patients selected as control group,they were given De Vega purposes banding surgery at the same time in the replacement of mitral valve.The index of operation and echocardiogram after 2 weeks and 6 months were observed and compared.Results Two groups of patients were discharged.Right atrium transverse diameter,right ventricle transverse diameter and tricuspid regurgitation by ultrasonic examination after 2 weeks and 6 months were significantly improved,there were statistical differences (P < 0.05),and the indexes in treatment group were significantly better than those in

  13. Robotic Transcatheter Mitral Valve Replacement Using the Sapien XT in the Setting of Severe Mitral Annular Calcification.

    Koeckert, Michael S; Loulmet, Didier F; Williams, Mathew R; Neuburger, Peter J; Grossi, Eugene A


    We describe the use of the Sapien XT, placed in the mitral position using a totally endoscopic robotic approach in a 76-year-old man with extensive circumferential mitral calcifications and severe stenosis. The patient was at high risk for traditional open surgery and a large mitral valve annulus prevented safe transcatheter deployment due to size mismatch. Our novel approach offered a minimally invasive technique for native mitral valve replacement in a high-risk patient with anatomical constraints prohibitive to conventional approaches. doi: 10.1111/jocs.12737 (J Card Surg 2016;31:303-305).

The systemic rheumatic illnesses commonly complicating pregnancy are systemic lupus erythematosus (SLE), antiphospholipid syndrome (APS), rheumatoid arthritis (RA), scleroderma.

  15. Diffuse Alveolar Hemorrhage due to Acute Mitral Valve Regurgitation.

    Marak, Creticus P; Joy, Parijat S; Gupta, Pragya; Bukovskaya, Yana; Guddati, Achuta K


    Diffuse alveolar hemorrhage (DAH) can be caused by several etiologies including vasculitis, drug exposure, anticoagulants, infections, mitral valve stenosis, and regurgitation. Chronic mitral valve regurgitation (MR) has been well documented as an etiological factor for DAH, but there have been only a few cases which have reported acute mitral valve regurgitation as an etiology of DAH. Acute mitral valve regurgitation can be a life-threatening condition and often requires urgent intervention. In rare cases, acute mitral regurgitation may result in a regurgitant jet which is directed towards the right upper pulmonary vein and may specifically cause right-sided pulmonary edema and right-sided DAH. Surgical repair of the mitral valve results in rapid resolution of DAH. Acute MR should be considered as a possible etiology in patients presenting with unilateral pulmonary edema, hemoptysis, and DAH.

  17. [Acute rheumatic fever].

    Maier, Alexander; Kommer, Vera


    We report on a young women with acute rheumatic fever. Acute rheumatic fever has become a rare disease in Germany, especially in adults. This carries the risk that it can be missed in the differential diagnostic considerations of acute rheumatic disorders and febrile status. If rheumatic fever is not diagnosed and treated correctly, there is a considerable risk for rheumatic valvular heart disease. In this article diagnosis, differential diagnosis and therapy of rheumatic fever are discussed extensively.

  18. Parabolic resection for mitral valve repair.

    Drake, Daniel H; Drake, Charles G; Recchia, Dino


    Parabolic resection, named for the shape of the cut edges of the excised tissue, expands on a common 'trick' used by experienced mitral surgeons to preserve tissue and increase the probability of successful repair. Our objective was to describe and clinically analyze this simple modification of conventional resection. Thirty-six patients with mitral regurgitation underwent valve repair using parabolic resection in combination with other techniques. Institution specific mitral data, Society of Thoracic Surgeons data and preoperative, post-cardiopulmonary bypass (PCPB) and postoperative echocardiography data were collected and analyzed. Preoperative echocardiography demonstrated mitral regurgitation ranging from moderate to severe. PCPB transesophageal echocardiography demonstrated no regurgitation or mild regurgitation in all patients. Thirty-day surgical mortality was 2.8%. Serial echocardiograms demonstrated excellent repair stability. One patient (2.9%) with rheumatic disease progressed to moderate regurgitation 33 months following surgery. Echocardiography on all others demonstrated no or mild regurgitation at a mean follow-up of 22.8+/-12.8 months. No patient required mitral reintervention. Longitudinal analysis demonstrated 80% freedom from cardiac death, reintervention and greater than moderate regurgitation at four years following repair. Parabolic resection is a simple technique that can be very useful during complex mitral reconstruction. Early and intermediate echocardiographic studies demonstrate excellent results.




    Full Text Available CONTEXT (B ACKGROUND: Rheumatic Heart disease is still a leading cause of valvular disease in developing countries like India and constitutes 10 to 50% of the cardiac patients in Indian hospitals. Echocardiography is a very sensitive investigation for the diagnosis of Rheumatic Carditis and its sequalae like Mitral, Aortic and Tricuspid valve disease as well as sub clinical Carditis. AIMS & OBJECTIVES: To study the profile, severity and gender based differences of valvular lesions on the Trans Thoracic Echocardiographic records of children diagnosed as Acute Rheumatic fever/ Rheumatic Heart disease. MATERIALS & METHODS: This study was conducted during D ecember’2014 by reviewing the records of trans thoracic Echocardiographic reports of our 36 cases (childhood Acute Rheumatic fever/ Rheumatic Heart disease cases for type and degree of valvular involvement according to AHA guidelines. RESULTS: Mitral valv e was involved most often (23 cases – 63.89%. Severe Mitral regurgitation is the common type of valvular lesions both in Boys and Girls (19.44% and 25% respectively. Isolated Aortic valve/ Tricuspid valve involvement was not found in our study. Mixed les ions were seen most often than pure isolated valvular lesions. CONCLUSION: Mitral valve was most commonly affected, while Regurgitant lesions were more common than Stenotic lesions and most severe in children less than 15 years age group. Aortic Regurgitat ion (AR was found more commonly in Girls than Boys in our study. But all these cases of AR had some other valvular involvement as Mixed lesions. Therefore Echocardiography should be done routinely for patients with Rheumatic Heart Disease, focusing on you nger population to facilitate diagnosis and definitive treatment before complications set in.

  20. The Role of Interleukin-13 in Patients with Rheumatic Valvular Fibrosis: A Clinical and Histological Study.

    Liu, Qi; Qiao, Wei-Hua; Li, Fei-fei; Deng, Peg; Hu, Zhi-Wei


    Interleukin (IL)-13 is a major inducer of fibrosis in many chronic infectious diseases, yet few studies have reported its role in valvular fibrosis in patients with rheumatic heart disease (RHD). The study aim was to investigate the role of IL-13 in mitral valvular fibrosis in patients with RHD. Peripheral blood samples were collected from surgical patients with RHD (n = 18) and from healthy controls (n = 9). Serum levels of IL-13 and interferon (IFN)-gamma were analyzed using ELISA. Rheumatic mitral valves removed from surgical patients with RHD, and normal mitral valves, were obtained at autopsy. The expression and distribution of collagen I, collagen III, and IL-13Ralpha1 were examined by immunohistochemical staining, the degree of which was measured using computed imaging analysis. Higher IL-13 levels were observed in RHD patients (15.16 +/- 9.62 pg/ml; p valves, rheumatic mitral valves expressed high levels of collagen I (0.01931 +/- 0.00159 versus 0.01183 +/- 0.00207; p heart interstitial cells, while IL-13Ralpha1 was expressed in the endothelial cells and smooth muscle cells of the blood vessels, and in interstitial cells. Patients with RHD showed increased serum levels of IL-13 compared to healthy controls. IFN-gamma levels were clearly different among RHD patients and healthy controls. The expression of collagens I and III and IL-13Ralpha1 was higher in rheumatic mitral valves compared to normal mitral valves. IL-13 may induce mitral valvular fibrosis in RHD.

  1. Late results of mitral valve repair with glutaraldehyde-treated autologous pericardium.

    Shomura, Yu; Okada, Yukikatsu; Nasu, Michihiro; Koyama, Tadaaki; Yuzaki, Mitsuru; Murashita, Takashi; Fukunaga, Naoto; Konishi, Yasunobu


    Mitral valve repair is an established surgical procedure for treating severe organic mitral regurgitation. The mechanisms of mitral regurgitation due to infective endocarditis include rheumatic disease and congenital diseases such as a lack of leaflet tissue, and thus additional material is required to create a functional coaptation surface. We review our experience with 139 patients who underwent mitral valve repair with glutaraldehyde-treated autologous pericardium to treat organic mitral regurgitation between March 1992 and November 2011. Mitral valve disease mainly consisted of infective endocarditis in 51 patients (active, n = 32; healed, n = 19) and rheumatic disease in 47. This procedure was also applied to 12 patients who required reoperation after mitral valve repair for degenerative, congenital, or rheumatic mitral regurgitation. The mean follow-up was 4.5 ± 4.3 years (maximum 19.1). Actuarial survival at 10 years was 84% ± 5%. Eleven reoperations proceeded at a mean of 68 months after surgery. The causes of reoperation were rheumatic disease progression (n = 4), infection (n = 3), patch dehiscence (n = 2), progressive fibrosis of the remaining mitral valve tissue after infective endocarditis (n = 1), and patch tear (n = 1). Mitral valves were replaced in 8 patients and re-repaired in 3 patients. The autologous pericardium was not calcified at the time of reoperation. The rate of freedom from reoperation was 82% ± 7% at 10 years. Mitral valves that might otherwise require replacement can be durably and predictably repaired using glutaraldehyde-treated autologous pericardium. Copyright © 2013 The Society of Thoracic Surgeons.

  2. Rheumatic Fever.

    Visvanathan; Manjarez; Zabriskie


    There have been numerous reports stating that treatment of acute rheumatic fever with either aspirin or corticosteroids does not alter the long-term outcome of rheumatic heart disease. Yet, it should be emphasized that most of these studies were carried out with the first generic corticosteroids before the advent of the more active and more potent corticosteroid agents. In spite of this caveat, there is no question that all the clinical and laboratory parameters of inflammation (erythrocyte sedimentation rate, C-reactive protein) return to normal much more rapidly with corticosteroids than with aspirin alone. It is therefore our belief that steroids should be used when clinical and laboratory evidence of carditis exists, and aspirin should be reserved for cases of acute rheumatic arthritis with no evidence of carditis. The incidence of long-term valvular disease in active carditis may be decreased with steroid therapy. For example, the number of valve replacements differs markedly in centers that do use steroids and in those that do not. In Capetown, South Africa, where steroids are routinely used for carditis, valve replacement is quite rare. In contrast, in Johannesburg, where steroids are rarely used, the rate of valve replacement is quite high. The racial backgrounds of both groups of patients are similar, thus eliminating the question of racial differences. Concerning secondary prophylaxis, there is also controversy concerning the best second-line therapy. It is now well known that monthly intramuscular injections of benzathine penicillin are really effective for only 20 days. Thus, there is a window in which penicillin coverage is not adequate. To circumvent this problem, some investigators give benzathine penicillin every 3 weeks. These injections are quite painful, however, and it has been our "rule" that compliance with this treatment is inversely proportional to the ratio of the size of the child to the mother. In our own experience over 30 years with the

    This lecture-style paper highlights all major problems pertinent to rheumatic fever Definition of acute RF and chronic rheumatic heart disease is proposed and desirability of the use of these terms in clinical practice is explained. Present-day epidemiology of RF is described with reference to marked differences in its prevalence in developed and developing countries. Modern classification of acute RF is described as adopted by the Russian Association of Rheumatologists and recommended for the use in Russian medical facilities. Discussion of etiological issues is focused on such virulence factors as beta-hemolytic streptococcus A and genetic predisposition confirming hereditary nature of RE Its clinical features are described along with laboratory and instrumental methods applied for its diagnostics. Large and small diagnostic criteria of RF are considered. Special attention is given to the treatment of RF and its complications (antibiotic, pathogenetic, and drug therapy). Its primary and secondary prophylaxis is discussed in detail, preparations for the purpose are listed (with doses and duration of application). In conclusion, criteria for the efficacy of therapy are presented along with indications for hospitalization and emergency treatment.

  4. Two-Dimensional Echo-cardiographic Estimation of the Size of the Mitral Valve Annulus



    Full Text Available The diameter of the mitral annulus as measured on the long axis by two-dimensional echocardiogram was found to correlate well with the size of the sewing ring used to replace the mitral valve in 35 consecutive patients. The size of the prosthesis which was used could be predicted within 1 mm of error in 83% of the mitral stenosis (MS patients and in 76% of the mitral regurgitation (MR patients in the study. Preoperative echocardiographic estimation of the size of the mitral valve annulus and prediction of the sewing ring size of the prosthetic valve used could reduce the incidence of valve prosthesis-patient mismatch.

  5. Emergency mitral valve replacement and cesarean section in parturients: Two case reports

    P S Nagaraja


    Full Text Available Cardiac surgery during pregnancy using cardiopulmonary bypass has a maternal mortality rate (MMR of about 3-15%. Cardiopulmonary bypass, in addition, alters placental perfusion, which can increase infant mortality. Here, we report two cases of parturients with severe mitral stenosis, who developed acute mitral regurgitation (MR after percutaneous transluminal mitral commissurotomy (PTMC due to anterior mitral leaflet tear. They were posted for emergency mitral valve replacement (MVR followed by cesarean section. Altering the routine cardiopulmonary bypass and anesthesia protocol resulted in a favorable maternal and fetal outcome.

    Independent determinants of sudden death were left ventricular ejection fraction and atrial fibrillation. The main cause of death in patients with mitral valve stenosis is a thromboembolism from the left heart chambers to systemic circulation, and the risk of the latter increases with atrial fibrillation. There is no sudden cardiac death in mitral valve stenosis. The absence of left ventricular remodeling in mitral valve stenosis probably explains this finding. Onset of symptoms and signs of left ventricular dysfunction are the main predictors of sudden death and are indications for surgery. It should be emphasized that the database of sudden cardiac death in patients with valvular heart disease is very limited compared to patients with coronary heart disease and cardiomyopathies. Some issues related to predictors and mechanisms of SCD are currently poorly understood, therefore prevention of sudden cardiac death is difficult, especially in asymptomatic patients.

  7. Left coronary artery stenosis causing left ventricular dysfunction in two children with supravalvular aortic stenosis.

    Yildiz, Okan; Altin, Firat H; Kaya, Mehmet; Ozyılmaz, Isa; Guzeltas, Alper; Erek, Ersin


    Congenital supravalvar aortic stenosis (SVAS) is an arteriopathy associated with Williams-Beuren syndrome (WBS) and other isolated elastin gene deletions. Cardiovascular manifestations associated with WBS are characterized by obstructive arterial lesions such as SVAS and pulmonary artery stenosis in addition to bicuspid aortic valve and mitral valve prolapse. However, coronary artery ostial stenosis may be associated with SVAS, and it increases the risk of sudden death and may complicate surgical management. In this report, we present our experience with two patients having SVAS and left coronary artery ostial stenosis with associated left ventricular dysfunction. © The Author(s) 2014.

  8. [Congenital aortic stenosis].

    Yamaguchi, M


    Recent advances in and controversies concerning the management of children with congenital valvular aortic stenosis are discussed. In neonates with critical aortic stenosis, improved survival has recently been reported after surgical open valvotomy and balloon valvuloplasty, although it is difficult at this point to compare the results of the two procedures and determine their differential indications. Good results have also been achieved after extended aortic valvuloplasty for recurrent aortic stenosis and/or insufficiency, but the length of follow-up in these patients is still short. The technique first reported in 1991 for bilateral enlargement fo a small annulus permits the insertion of an aortic valve 3-4 sizes larger than the native annulus. It entails no risk of distorting the mitral valve, damaging the conduction system or important branches of the coronary arteries, or resulting in left ventricular dysfunction. The Ross procedure is now widely applied in the West, with reports of early mortality rates of less than 5% and event-free survival rates of 80-90% during follow-up of 4-8 years. Longer follow-up and continued careful evaluation are required to resolve the issue of possible dilatation and subsequent neoaortic valve dysfunction and pulmonary stenosis due to allograft degeneration after pulmonary autograft root replacement in children.

  9. Rheumatic fever reappraised

    Ulrik Baandrup


    @@ Rheumatic fever is a complication following an episode of group A streptococcal pharyngitis. It is an acute immunologically mediated, multisystem inflammatory disorder. Acute rheumatic heart disease during the active phase of rheumatic fever sometimes progresses to chronic rheumatic heart disease. Despite its declining importance in industrialised countries rheumatic fever remains the leading cause of death from heart disease in children and young adults in less developed regions. Fifteen to twenty million new cases emerge every year in developing countries.1

    Objective To evaluate the long-term effect of mitral valve stenosis treated by percutaneous balloon mitral valvuloplasty (PBMV). Methods 680 cases of rheumatic mitral valve stenosis were treated by PBMV with Inoue single balloon. 394 cases were observed 38±14 months. Results Mitral valve dilatation resulted in a decrease in left atrail diameter from (44±6)mm, a decline in transmitral valve pressure gradient from (18.2±6.8)mm?Hg to (7.2±3.8)mm?Hg, and an increase in mitral valve area from (1.04±0.21)cm2 to (1.98±0.55)cm2. 8 cases of severe restenesis developed. Among them a second PBMV is required in 5 cases, 3 cases received mitral replacement. Conclusion Follow-up data shows PBMV can achieve excellent long-term results. The condition of the valves especially the severity of the subvavular lesion are the most important factors which affect the long-term effect.%目的 观察经皮二尖瓣球囊扩张术(PBMV)治疗风湿性心脏病(风心病)二尖瓣狭窄的中、远期疗效。方法 采用Inoue单球囊对680例风心病二尖瓣狭窄者行PBMV术治疗,其中394例进行了随访。平均随访时间(36±14)个月。结果 二尖瓣平均跨瓣压差由(18.2±6.8)mm Hg降至(7.2±3.8)mm Hg,瓣口面积由(1.04±0.21)cm2增至(1.98±0.55)cm2,左房内径由(44±8)mm降至(38±6)mm;8例出现明显再狭窄,其中5例再次PBMV术,3例行瓣膜置换术。结论 随访结果证实,PBMV治疗风心病二尖瓣狭窄的中、远期效果良好,瓣膜条件特别是瓣下病变的程度是影响中、远期疗效的重要因素。

    Conclusion: During pregnancy, emergent BMV is safe and feasible in patients with symptomatic mitral stenosis and severe pulmonary edema. There is marked symptomatic relief, along with excellent maternal and fetal outcomes.

  12. Aortic valve replacement with the Nicks annulus enlargement procedure 12 years after mitral valve replacement.

    Kazama, S; Kurata, A; Yamashita, Y


    An aortic valve replacement was successfully performed employing the Nicks annulus enlargement procedure in a case of aortic valve stenosis with small annulus 12 years after mitral valve replacement. Previous mitral valve replacement does not preclude feasibility of the Nicks procedure.

  13. Prosthetic valve thrombosis in a patient with mitral valve replacement.

    Bilal, Muhammad; Khan, Muhammad Shahzeb; Haseeb, Abdul; Khan, Abdul Bari


    Prosthetic valve thrombosis within one year after mitral valve replacement is rarely seen in patients on warfarin therapy and without any risk factor. Here, we describe a case of a 39-year- old female, who presented with dyspnoea and shortness of breath 11 months after mitral valve replacement. The echocardiogram revealed severe valvular stenosis due to presence of clots on the mitral valve and restricted motion of the mitral leaflets. As a result of deterioration of general condition and haemodynamic un-stability, plan was made to re-operate for her valve replacement surgery. This case report highlights the diagnosis, prevention and management of patients with prosthetic valve thrombosis following mitral valve replacement.

  14. Mitral Valve Surgery in Patients with Systemic Lupus Erythematosus

    Mahnoosh Foroughi


    Full Text Available Valvular heart disease is the common cardiac manifestation of systemic lupus erythematosus (SLE with a tendency for mitral valve regurgitation. In this study we report a case of mitral valve replacement for mitral stenosis caused by Libman-Sacks endocarditis in the setting of SLE. In addition, we provide a systematic review of the literature on mitral valve surgery in the presence of Libman-Sacks endocarditis because its challenge on surgical options continues. Surgical decision depends on structural involvement of mitral valve and presence of active lupus nephritis and antiphospholipid antibody syndrome. Review of the literature has also shown that outcome is good in most SLE patients who have undergone valvular surgery, but association of antiphospholipid antibody syndrome with SLE has negative impact on the outcome.

  15. Minimally Invasive Mitral Valve Replacement and Transfemoral Aortic Valve Implantation.

    Rustenbach, Christian; Baumbach, Hardy; Hill, Stephan; Franke, Ulrich F W


    The case is reported of a symptomatic elderly patient with severe mitral regurgitation, severe aortic valve stenosis, and coronary heart disease. The coronary artery disease had been interventionally treated four years previously with stent implantation into the right coronary artery. Published studies have shown that a combination of mitral and aortic valve surgery is associated with a significantly increased risk of mortality and morbidity, particularly in elderly patients. In the present patient, both valvular malformations were successfully treated with a single-step interdisciplinary approach, namely an initial surgical mitral valve replacement followed by transfemoral transcatheter aortic valve replacement.

  16. Surgical Treatment of Congenital Mitral Valve Dysplasia.

    Vida, Vladimiro L; Carrozzini, Massimiliano; Padalino, Massimo; Milanesi, Ornella; Stellin, Giovanni


    Congenital mitral valve (MV) dysplasia is a relatively rare and highly complex cardiac disease. We present our results and illustrate the techniques used to repair these valves. Between 1972 and 2014, 100 consecutive patients underwent surgical repair of congenital MV dysplasia at our institution. Predominant MV regurgitation was present in 53 patients (53%) whereas mitral stenosis was prevalent in 47 (47%). There were five early (5%) and eight late deaths (9%). Actuarial survival was 95%, 94%, and 93% at 5, 10, and 20 years, respectively. Sixteen patients (18%) required reintervention due to subsequent MV dysfunction. Actuarial freedom from reintervention for MV dysfunction was 95%, 92%, and 89% at 5, 10, and 20 years, respectively. The mechanism underlying the valve dysfunction in congenital mitral valve dysplasia is multifactorial and requires the application of a variety of surgical techniques for repair. doi: 10.1111/jocs.12743 (J Card Surg 2016;31:352-356). © 2016 Wiley Periodicals, Inc.

  17. [Functional mitral regurgitation].

    Sade, Leyla Elif


    Functional mitral regurgitation (FMR) is the mitral regurgitation that occurs due to myocardial disease in the presence of normal mitral valve leaflets. This scenario has the different characteristics than the organic mitral regurgitation. Functional mitral regurgitation is a disease of the ventricle and occurs by the deformation of the mitral valve leaflets. This morbid entity is frequent and has bad prognosis. Functional mitral regurgitation is the result of complex pathophysiologic process including left ventricular local and global remodeling, mitral annular and papillary muscle dysfunction, and left ventricular dysfunction. The dynamic behavior of FMR complicates the quantification of the regurgitation. Exercise stress echocardiography is of particular importance in the evaluation of the hemodynamic burden of FMR. Particular pathophysiological properties of the FMR necessitate different therapeutic approaches than the current ones for classical mitral regurgitation.

  18. Exuberant accessory mitral valve tissue with possible true parachute mitral valve: a case report

    Nikolic Aleksandra


    Full Text Available Abstract Introduction A parachute mitral valve is defined as a unifocal attachment of mitral valve chordae tendineae independent of the number of papillary muscles. Data from the literature suggests that the valve can be distinguished on the basis of morphological features as either a parachute-like asymmetrical mitral valve or a true parachute mitral valve. A parachute-like asymmetrical mitral valve has two papillary muscles; one is elongated and located higher in the left ventricle. A true parachute mitral valve has a single papillary muscle that receives all chordae, as was present in our patient. Patients with parachute mitral valves during childhood have multilevel left-side heart obstructions, with poor outcomes without operative treatment. The finding of a parachute mitral valve in an adult patient is extremely rare, especially as an isolated lesion. In adults, the unifocal attachment of the chordae results in a slightly restricted valve opening and, more frequently, valvular regurgitation. Case presentation A 40-year-old Caucasian female patient was admitted to a primary care physician due to her recent symptoms of heart palpitation and chest discomfort on effort. Transthoracic echocardiography showed chordae tendineae which were elongated and formed an unusual net shape penetrating into left ventricle cavity. The parasternal short axis view of her left ventricle showed a single papillary muscle positioned on one side in the posteromedial commissure receiving all chordae. Her mitral valve orifice was slightly eccentric and the chordae were converting into a single papillary muscle. Mitral regurgitation was present and it was graded as moderate to severe. Her left atrium was enlarged. There were no signs of mitral stenosis or a subvalvular ring. She did not have a bicuspid aortic valve or coarctation of the ascending aorta. The dimensions and systolic function of her left ventricle were normal. Our patient had a normal body habitus

  19. [Rheumatic diseases in pregnancy].

    Märker-Hermann, E; Bauer, H; Gromnica-Ihle, E


    Rheumatic diseases can influence the reproduction, the course of pregnancy and the development of the fetus. The inflammatory rheumatic disease itself can be modulated in its activity in terms of amelioration or exacerbation of the rheumatic symptoms. The associations between rheumatic diseases and pregnancy will be illustrated with rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, and systemic lupus erythematosus as examples. Antirheumatic drug therapy during pregnancy and the breast feeding period has to be adapted critically.

  20. Predictors of Developing Significant Mitral Regurgitation Following Percutaneous Mitral Commissurotomy with Inoue Balloon Technique

    Abdelfatah A. Elasfar


    Full Text Available Background. Despite the high technical expertise in percutaneous mitral commissurotomy (PMC, mitral regurgitation (MR remains a major procedure-related complication. The aim of this work is to find out the most sensitive and applicable predictors of development of significant mitral regurgitation (SMR following percutaneous mitral commissurotomy using Inoue balloon technique. Methods. We studied prospectively the preprocedural (clinical, echocardiography, and hemodynamic and procedural predictors of significant mitral regurgitation (identified as increase of ≥2/4 grades of pre-PMC MR by color Doppler flow mapping following valvuloplasty using Inoue balloon in 108 consecutive patients with severe mitral stenosis. Multiple stepwise logistic regression analysis was performed for variables found positive on univariate analysis to determine the most important predictor(s of developing SMR. Results. The incidence of SMR following PMC using Inoue technique was 18.5% (10 patients. MV scoring systems were the only variables that showed significant differences between both groups (Group A without SMR and Group B with SMR. However, no clinical, other echocardiographic measurements, hemodynamic or procedural variables could predict the development of SMR. Using multiple regression analysis, the best predictive factor for the risk of SMR after Inoue BMV was the total MR-echo score with a cutoff point of 7 and a predictive percentage of 97.7%. Conclusions. The total MR-echo score is the only independent predictor of SMR following PMC using Inoue technique with a cutoff point of 7.

  1. Incidental histological diagnosis of acute rheumatic carditis: case report and review of the literature.

    Guilherme S. Spina


    Full Text Available Rheumatic fever remains endemic in many countries and frequently causes heart failure due to severe chronic rheumatic valvular heart disease, which requires surgical treatment. Here, we report on a patient who underwent an elective surgical correction for mitral and aortic valvular heart disease and had a post-operative diagnosis of acute rheumatic carditis. The incidental finding of Aschoff bodies in myocardial biopsies is frequently reported in the nineteenth-century literature, with prevalences as high as 35%, but no clinical or prognostic data on the patients is included. The high frequency of this finding after cardiac surgery in classical reports suggests that these patients were not using secondary prophylaxis for rheumatic fever. We discuss the clinical diagnosis of acute rheumatic myocarditis in asymptomatic patients and the laboratorial and imaging methods for the diagnosis of acute rheumatic carditis. We also discuss the prognostic implications of this finding and review the related literature.

  2. Maternal and fetal outcomes in rheumatic heart disease in pregnancy

  3. [Percutaneous mitral commissurotomy using Inoue's balloon during pregnancy].

    Murillo, H; Ayala, F; Badui, E; Almazán, A; Solorio, S; Enciso, R; Madrid, R; Lepe, L; Rangel Abundis, A; Chávez, E


    The authors present three cases of pregnant women with symptomatic severe mitral stenosis with a mean age of 28.6 +/- 2.3 years, and during 27.6 +/- 1.52 weeks of pregnancy. Two patients were in class III and one in class IV of the New York Heart Association (NYHA). All patients had a mitral valvular area equal or less than 1 cm2, with a Wilkins score of 7 to 9 and mitral insufficiency grade I in two cases; two, had severe pulmonary arterial hypertension (mean > 50 mm Hg). After Percutaneous Mitral Valvuloplasty (PMV) the mitral valve measured by 2D echocardiography increased form 0.83 +/- 0.2 cm2 to 1.8 +/- 0.15 cm2; the mean transmitral gradient diminished from 13 +/- 3.4 mm Hg to 3.6 +/- 1.15 mm Hg; the degree of mitral insufficiency was no modified in neither case. Hemodynamic results revealed increasing of the mitral valve from 0.83 +/- 0.18 cm2 to 2.23 +/- 0.3 cm2; the mean mitral gradient decreased from 21.6 +/- 9 to 4.3 +/- 0.5 mm Hg; the mean left atrial pressure from 30 +/- 12 to 12.3 +/- 4 mm Hg; the mean pressure of the pulmonary artery diminished suddenly from 44.3 +/- 16 to 25.6 +/- 11 mm Hg. The average fluoroscopic time was 15.3 +/- 3 minutes. There were no complications. The patients were discharged 48 hours after the procedure and continued their pregnancies in class I NYHA, which resolved in a non complicated vaginal delivery with normal products. We conclude that PMV is a safe and useful therapy in pregnant patient with severe mitral stenosis refractory to medical treatment.

  6. Transapical Mitral Valve-in-Valve Replacement in Patient With Previous Complex Sternal Reconstruction.

    Hynes, Conor F; Fatemi, Omid; Sharma, Aditya C; Nagy, Christian D; Trachiotis, Gregory D


    We present a complex case of a transapical redo mitral valve-in-valve replacement. Repeat mitral valve replacement was indicated for severe symptomatic bioprosthetic stenosis. In addition to the patient's numerous comorbidities that included diabetes, hepatic cirrhosis, ischemic cardiomyopathy, and atrial flutter, he had undergone a previous open mitral valve replacement that was complicated by sternal dehiscence requiring extensive chest wall reconstruction. Transapical approach was performed through left minithoracotomy incision with balloon-expandable valve. Transapical valve-in-valve replacement of a stenotic mitral bioprosthesis is a viable solution in a patient with previous complex chest wall reconstruction and multiple comorbidities.

  7. Disturbance of intracardiac hemodynamics in children with chronic rheumatic cardiac disease

    Kondratiev V.A.


    Full Text Available By means of Doppler echocardiography there have been studied disturbances of intracardiac hemodynamics in 44 children aged 8-17 years with chronic rheumatic cardiac disease and developed mitral aortal and combined heart defects, as well as in chronic rheumatic cardiac disease without developed valvar defect. Differential approach has been defined to administration of inhibitors of angiotensin-converting factor in rheumatic heart defects: developed insufficiency of mitral and/or aortal valves II-III stage leads to remodeling of the left heart portions with developing chronic insufficiency of blood circulation, being an index for prolonged, not less than a year usage of the angiotensin-converting factor. In the presence of isolated mitral regurgitation, I stage in children with chronic rheumatic cardiac disease usage of the angiotensin-converting factor may be cancelled due to insignificant disturbances of valvar hemodynamics and a small risk of developing blood circulation insufficiency. Timely sanation of chronic infection foci in nasopharynx (conservative and surgical treatment of chronic tonsillitis, adenoid vegetations, therapy of hemolytic streptococcus presence decreases risk of developing rheumatic heart defect in children suffered acute rheumatic fever.

  8. Asymptomatic post-rheumatic giant left atrium.

    Özkartal, Tardu; Tanner, Felix C; Niemann, Markus


    A 78-year-old asymptomatic woman was referred to our clinic for a second opinion regarding indication for mitral valve surgery. An echocardiogram showed a moderate mitral stenosis with a concomitant severe regurgitation. The most striking feature, however, was a giant left atrium with a parasternal anteroposterior diameter of 79 mm and a left atrial volume index of 364 mL/m². There are various echocardiographic definitions of a giant left atrium, which are mainly based on measurements of the anteroposterior diameter of the left atrium using M-mode in the parasternal long axis view. Since the commonly accepted method for echocardiographic evaluation of left atrial size is left atrial volume index, we propose a cut-off value of 140 mL/m(2) for the definition of a "giant left atrium".

  9. [Acute rheumatic fever in children, a diagnostic problem].

    Wieringa, J W; Ramaker, C; Wolf, B H M


    Three girls of Moroccan descent, aged 9, 10 and 7 years, presented with fever, joint pain and other symptoms. After Streptococcus infection and carditis were confirmed and the Jones criteria for acute rheumatic fever were met, the patients were treated with penicillin and acetylsalicylic acid. All 3 patients recovered. However, the second girl presented 2 months later with cardiac decompensation caused by valve disorders, after which aortic and mitral valvuloplasty was performed. The third girl developed joint pain again after 3 weeks and was diagnosed with juvenile idiopathic arthritis; treatment was adjusted accordingly. The prevalence of rheumatic heart diseases is 10-20 times higher in developing countries than in industrialised nations. The diagnosis 'acute rheumatic fever' should be considered in children of school age with unexplained fever, also when the Jones criteria have not yet been met. This may apply to migrant children in particular.

  10. Glottic stenosis.

    Stephenson, Kate A; Wyatt, Michelle E


    Glottic stenosis is a fixed, focal narrowing at the level of the laryngeal inlet, the true vocal cords. It may be either congenital or acquired and be related to a wide range of etiologies. The stenosis may be either anterior, posterior, or in rare cases, complete. Isolated glottic stenosis is rare; lesions often involve adjacent regions, namely the subglottis. A diagnosis is made from careful history and examination, including evaluation by microlaryngoscopy and bronchoscopy. The management of glottic stenosis is challenging and should be tailored to each individual case. A secure and adequate airway is the treatment priority alongside optimization of voice and laryngeal competence. Endoscopic and open techniques in either single or multiple stages have been described. Copyright © 2016. Published by Elsevier Inc.

  13. Supravalvular aortic stenosis with sudden cardiac death

    Pradeep Vaideeswar


    Full Text Available Sudden cardiac death (SCD most commonly results from previously undiagnosed congenital, acquired, or hereditary cardiac diseases. Congenital aortic valvular, subvalvular, and supravalvular disease with left ventricular outflow tract obstruction is an important preventable cause of sudden death. This report documents sudden death presumably due to acute myocardial ischemia in a young male with an undiagnosed supravalvular aortic stenosis (SVAS due to a rare association of isolation of coronary sinuses of Valsalva. Congenital supravalvular pulmonary stenosis and mitral valvular dysplasia were also present.

  14. Mitral valve prolapse.

    Gould, L; Gopalaswamy, C


    Mitral valve prolapse is a very common condition. It occurs in 4-5% of the population. It may be idiopathic or associated with a number of other conditions. Myxomatous degeneration is the underlying mechanism of mitral valve prolapse. Most patients with mitral valve prolapse have no symptoms. When symptoms do occur, palpitations, chest pain and dyspnea are the major complaints. The midsystolic click occasionally followed by the late systolic murmur are the typical physical findings. The echocardiogram plays a big role in the diagnosis of mitral valve prolapse. The beta blockers are used in the treatment of the symptomatic patient.

  15. Descriptive Analysis of In Vitro Cutting of Swine Mitral Cusps: Comparison of High-Power Laser and Scalpel Blade Cutting Techniques.

    Pinto, Nathali Cordeiro; Pomerantzeff, Pablo Maria Alberto; Deana, Alessandro; Zezell, Denise; Benetti, Carolina; Aiello, Vera Demarchi; Lopes, Luciana Almeida; Jatene, Fabio Biscegli; Chavantes, M Cristina


    The most common injury to the heart valve with rheumatic involvement is mitral stenosis, which is the reason for a big number of cardiac operations in Brazil. Commissurotomy is the traditional technique that is still widely used for this condition, although late postoperative restenosis is concerning. This study's purpose was to compare the histological findings of porcine cusp mitral valves treated in vitro with commissurotomy with a scalpel blade to those treated with high-power laser (HPL) cutting, using appropriate staining techniques. Five mitral valves from healthy swine were randomly divided into two groups: Cusp group (G1), cut with a scalpel blade (n = 5), and Cusp group (G2), cut with a laser (n = 5). G2 cusps were treated using a diode laser (λ = 980 nm, power = 9.0 W, time = 12 sec, irradiance = 5625 W/cm(2), and energy = 108 J). In G1, no histological change was observed in tissue. A hyaline basophilic aspect was focally observed in G2, along with a dark red color on the edges and areas of lower birefringence, when stained with hematoxylin-eosin, Masson's trichrome, and Sirius red. Further, the mean distances from the cutting edge in cusps submitted to laser application and stained with Masson's trichrome and Sirius red were 416.7 and 778.6 μm, respectively, never overcoming 1 mm in length. Thermal changes were unique in the group submitted to HPL and not observed in the cusp group cut with a scalpel blade. The mean distance of the cusps' collagen injury from the cutting edge was less than 1 mm with laser treatment. Additional studies are needed to establish the histological evolution of the laser cutting and to answer whether laser cutting may avoid valvular restenosis better than blade cutting.

  16. Overexpression of transforming growth factor-beta 1 in the valvular fibrosis of chronic rheumatic heart disease.

    Kim, Lucia; Kim, Do Kyun; Yang, Woo Ick; Shin, Dong Hwan; Jung, Ick Mo; Park, Han Ki; Chang, Byung Chul


    For the purpose of determining the pathogenic role of transforming growth factor-beta1 (TGF-beta 1) in the mechanism of chronic rheumatic heart disease, we evaluated the expression of TGF-beta 1, proliferation of myofibroblasts, and changes in extracellular matrix components including collagen and proteoglycan in 30 rheumatic mitral valves and in 15 control valves. High TGF-beta 1 expression was identified in 21 cases (70%) of rheumatic mitral valves, whereas only 3 cases (20%) of the control group showed high TGF-beta 1 expression (pvalves. High TGF-beta1 expression positively correlated with the proliferation of myofibroblasts (p=0.004), valvular fibrosis (pvalves (p=0.040). In conclusion, an ongoing inflammatory process, the expression of TGF-beta 1, and proliferation of myofibroblasts within the valves have a potential role in the valvular fibrosis, calcification, and changes in the extracellular matrix that lead to the scarring sequelae of rheumatic heart disease.

  17. Mitral balloon valvotomy, long-term results, its impact on severe pulmonary hypertension, severe tricuspid regurgitation, atrial fibrillation, left atrial size, left ventricular function

    Mohamed Eid Fawzy


    Full Text Available Percutaneous mitral balloon valvotomy (MBV was introduced in 1984 by Inoue who developed the procedure as a logical extension of surgical closed commissurotomy. Since then, MBV has emerged as the treatment of choice for severe pliable rheumatic mitral stenosis (MS. With increasing experience and better selection of patient, the immediate results of the procedure have improved and the rate of complications declined. When the reported complications of MBV are viewed in aggregate, complications occur at approximately the following rates: mortality (0–0.5%, cerebral accident (1–2%, mitral regurgitation (MR requiring surgery (0.9–2%. These complication rates compare favorably to those reported after surgical commissurotomy. Several randomized trials reported similar hemodynamic results with MBV and surgical commissurotomy. Restenosis after MBV ranges from 4% to 70% depending on the patient selection, valve morphology, and duration of follow-up. Restenosis was encountered in 31% of the author’s series at mean follow-up of 9 ± 5.2 years (range 1.5–19 years and the 10, 15, and 19 years restenosis-free survival rates were (78 ± 2% (52 ± 3% and (26 ± 4%, respectively, and were significantly higher for patients with favorable mitral morphology (MES ⩽ 8 at 88 ± 2%, 67 ± 4% and 40 ± 6%, respectively (P < 0.0001. The 10, 15, and 19 years event-free survival rates were 88 ± 2%, 60 ± 4% and 28 ± 7%, respectively, and were significantly higher for patients with favorable mitral morphology 92 ± 2%, 70 ± 4% and 42 ± 7%, respectively (P < 0.0001. The effect of MBV on severe pulmonary hypertension, concomitant severe tricuspid regurgitation, left ventricular function, left atrial size, and atrial fibrillation is addressed in this review.

  18. [Rheumatic diseases during pregnancy].

    Fischer-Betz, R


    The treatment of inflammatory rheumatic diseases, such as rheumatoid arthritis, spondylitis ankylosans and systemic lupus erythematosus, is improving continuously. This has lead to an increasing number of young patients with a wish to have children. Greater insight into the course of rheumatic diseases during pregnancy and post partum has enabled optimized support for women with rheumatic diseases wishing to have children. To ensure a favorable outcome, pregnancy should be started during a period of disease stability and should be monitored closely. A careful assessment of possible risks and the justified use of antirheumatic drugs before, during and after pregnancy are key issues for success.

    Nanjappa, Manjunath C; Bhat, Prabhavathi; Panneerselvam, Arunkumar


    We present a case where difficulty was encountered during balloon mitral valvotomy (BMV) because of severe submitral stenosis. As the orifice was 0.4 cm² at submitral level the BMV balloon catheter could not enter the left ventricle. We used a modified technique of liberating the submitral apparatus that facilitated successful BMV.

  20. Surgical treatment of tricuspid regurgitation after mitral valve surgery: a retrospective study in China

    Li Zong-Xiao


    Full Text Available Abstract Background Functional tricuspid regurgitation (TR occurs in patients with rheumatic mitral valve disease even after mitral valve surgery. The aim of this study was to analyze surgical results of TR after previous successful mitral valve surgery. Methods From September 1996 to September 2008, 45 patients with TR after previous mitral valve replacement underwent second operation for TR. In those, 43 patients (95.6% had right heart failure symptoms (edema of lower extremities, ascites, hepatic congestion, etc. and 40 patients (88.9% had atrial fibrillation. Twenty-six patients (57.8% were in New York Heart Association (NYHA functional class III, and 19 (42.2% in class IV. Previous operations included: 41 for mechanical mitral valve replacement (91.1%, 4 for bioprosthetic mitral valve replacement (8.9%, and 7 for tricuspid annuloplasty (15.6%. Results The tricuspid valves were repaired with Kay's (7 cases, 15.6% or De Vega technique (4 cases, 8.9%. Tricuspid valve replacement was performed in 34 cases (75.6%. One patient (2.2% died. Postoperative low cardiac output (LCO occurred in 5 patients and treated successfully. Postoperative echocardiography showed obvious reduction of right atrium and ventricle. The anterioposterior diameter of the right ventricle decreased to 25.5 ± 7.1 mm from 33.7 ± 6.2 mm preoperatively (P Conclusion TR after mitral valve replacement in rheumatic heart disease is a serious clinical problem. If it occurs or progresses late after mitral valve surgery, tricuspid valve annuloplasty or replacement may be performed with satisfactory results. Due to the serious consequence of untreated TR, aggressive treatment of existing TR during mitral valve surgery is recommended.

    以手术中直接测量的二尖瓣口面积为对照标准,将在超声心动图检查中采用近端血流汇聚法,两维超声直接测定法和压力降半时间法测量的二尖瓣口面积与之进行比较.发现三种超声测量方法测量结果,均与术中测量结果密切相关.相关系数分别为0.64、0.96和0.70.其中以两维超声直接测量法与手术中测量结果相关性最佳.这表明近端血流汇聚法在二尖瓣狭窄的定量诊断中有实用价值,但影响其测量准确性因素不少,在目前方法和经验未完全成熟的情况下,此方法测量的精确性尚不及两维超声直接测定的结果.%Mitral valve areas(MVA)measured by three ultrasonic methods i.e.color Doppler proximal flow convergence(PFC),two-dimensional echocardiography(2-DE)and Doppler pressure halftime were compaired with dath obtained by the direct measurement during operation.The results suggest that the color Dopper PFC in the quantification of MVA has its practical value but there are some factors affecting its correct measurement.Because of the inadequacy of the method and experience,the accuracy of PFC is inferior to 2-DE at present.

  2. Differential cell-matrix responses in hypoxia-stimulated aortic versus mitral valves.

    Sapp, Matthew C; Krishnamurthy, Varun K; Puperi, Daniel S; Bhatnagar, Saheba; Fatora, Gabrielle; Mutyala, Neelesh; Grande-Allen, K Jane


    Tissue oxygenation often plays a significant role in disease and is an essential design consideration for tissue engineering. Here, oxygen diffusion profiles of porcine aortic and mitral valve leaflets were determined using an oxygen diffusion chamber in conjunction with computational models. Results from these studies revealed the differences between aortic and mitral valve leaflet diffusion profiles and suggested that diffusion alone was insufficient for normal oxygen delivery in mitral valves. During fibrotic valve disease, leaflet thickening due to abnormal extracellular matrix is likely to reduce regional oxygen availability. To assess the impact of low oxygen levels on valve behaviour, whole leaflet organ cultures were created to induce leaflet hypoxia. These studies revealed a loss of layer stratification and elevated levels of hypoxia inducible factor 1-alpha in both aortic and mitral valve hypoxic groups. Mitral valves also exhibited altered expression of angiogenic factors in response to low oxygen environments when compared with normoxic groups. Hypoxia affected aortic and mitral valves differently, and mitral valves appeared to show a stenotic, rheumatic phenotype accompanied by significant cell death. These results indicate that hypoxia could be a factor in mid to late valve disease progression, especially with the reduction in chondromodulin-1 expression shown by hypoxic mitral valves. © 2016 The Author(s).

  3. Effects of Mitral Balloon Valvuloplasty on Left Ventricular Systolic Functions: Assessment with Color Tissue Doppler

    Cevat Kırma


    Full Text Available Objective: Left ventricular (LV systolic functions are generally depressed in Mitral Stenosis (MS. Recovery of LV systolic functions demonstrated with 2D echocardiography in some patients by mitral balloon valvuloplasty (MBV. Systolic mitral annular velocity (S' by Tissue Doppler Imaging (TDI predicts LV systolic function. We aimed to evaluate early effects of MBV on LV systolic function by TDI.Methods: Forty-eight consecutive patients included to the study (39 female, 36±10 years. A full transthoracic echocardiographic study (TTE including left ventricular ejection fraction assessment by teicholz method and mitral annular color TDI assessment was performed 24 hours before and after MBV in all patients. MBV performed by Inoue technique under guidance of TTE. Analysis of mitral lateral annular S' wave velocity was performed immediately after echocardiographic examination. Results: MBV performed successfully in 43 patients (Group A, and severe mitral regurgitation developed in 5 patients(Group B. Mitral valve area, and S’ wave velocity increased, mean and maximum mitral gradient, and left atrial diameter, and systolic pulmonary artery pressure (PAP were reduced significantly by MBV in group A patients (p<0.01, =0.046, <0.01, <0.01, <0.01, <0.01, respectively. But, only mitral valve area increased significantly ingroup B patients (p<0.01. LVEF by teicholz did not change significantly in both groups. Conclusion: Improvements of LV systolic functions after successfull MBV can easily showed by color TDI where2D echocardiography could not indicate.

    Segreto, Antonio; De Salvatore, Sergio; Chiusaroli, Alessandro; Bizzarri, Federico; Van Wyk, Cornelius; Congiu, Stefano


    The case is described of an eight-year-old boy who required an operation for moderate mitral regurgitation due to a double-orifice mitral valve (DOMV). The DOMV, which was clearly demonstrated by transthoracic echocardiography, had a central fibrous bridge. Mitral valve repair using a 5/0 Prolene suture placed at the level of the superior commissure of each hole to stabilize the valve, and ring annuloplasty with Edwards Physio ring, was successfully performed. Intraoperative real-time transesophageal echocardiography showed the repaired DOMV to be without regurgitation or stenosis.

The patient was treated by non-invasive mechanical ventilation, and anticoagulation, cardiotonic, diuretic, eliminating sputum, antiasthmatic as well as anti-infectious drugs. The heart failure symptom of the patient improved, however the lung infection aggravated. Fungal infection was considered according to the clinical signs and laboratory examinations of the patient. Pharmaceutical cares were given to the patient by clinical pharmacists in respect of the selection and dose adjustment of the antifungal agent, fluctuations analysis of the international normalized ratio (INR) due to the interactions between the warfarin and other drugs, the treatment of electrolyte imbalance after long-term use of thiazide diuretic and monitoring the side effect of the antibacterials such as QT interval prolonged, ventricle speed torsade de pointe

  7. IL-10 and ET-1 as biomarkers of rheumatic valve disease

    Sydney Correia Leão


    Full Text Available Objective: To evaluate the immunological profile and gene expression of endothelin-1 (ET-1 in mitral valves of patients with rheumatic fever originated from a reference service in cardiovascular surgery. Methods: This was a quantitative, observational and cross-sectional study. Thirty-five subjects (divided into four groups participated in the study, 25 patients with chronic rheumatic heart disease and ten control subjects. The mean age of the sample studied was 34.5 years. Seventeen of them (48.58% were male and 18 (51.42% were female. Inflammatory cytokines (TNF-α, IL-4 and IL-10 were measured and ten mitral valves of patients who underwent first valve replacement were collected for determination of gene expression of endothelin-1 by real time PCR. Results: Among the groups studied (patients vs. controls, there was a statistically significant difference in IL-10 levels (P=0.002, and no differences in other cytokines. Expression of endothelin-1 was observed in 70% of samples. Quantitatively, average of ET-1 expression was 62.85±25.63%. Conclusion: Inflammatory cytokine IL-10 participates in the maintenance of chronicity of rheumatic fever in patients who underwent valve replacement and those who are undergoing medical treatment. The expression of endothelin-1 in heart valve lesions in patients undergoing mitral valve replacement confirms its association with inflammatory activity in rheumatic fever.

  8. Right ventricular function before and after percutaneous balloon mitral valvuloplasty.

    Burger, W; Brinkies, C; Illert, S; Teupe, C; Kneissl, G D; Schräder, R


    Aim of this study was to evaluate right ventricular performance in patients with mitral stenosis and its modification by balloon valvuloplasty. Right ventricular volumes of 24 patients with postrheumatic mitral stenosis were determined by thermodilution 1 or 2 days before and 1 or 2 days after valvuloplasty. Right ventricular ejection fraction at rest was 43 (36-47)% (median and interquartile range). Right ventricular end-diastolic volume was 100 (86-119) ml/m2. Supine bicycle exercise (50 Watt) reduced right ventricular ejection fraction to 30 (29-37)% (P volume to 124 (112-141) ml/m2 (P improvement of right ventricular ejection fraction correlated inversely with the value of this parameter before valvuloplasty (r = -0.88, P volume (r = 0.57, P < 0.01). The right ventricular function curve, disturbed before commissurotomy, was reestablished by the procedure. In conclusion, at the here investigated stage of mitral stenosis right ventricular function is reversibly impaired. This is predominantly caused by the hemodynamic consequences of the valvular defect and not by an impairment of right ventricular myocardial function.

  11. Subglottic stenosis.

    Jefferson, Niall D; Cohen, Aliza P; Rutter, Michael J


    Subglottic stenosis (SGS) is a congenital or acquired condition characterized by a narrowing of the upper airway extending from just below the vocal folds to the lower border of the cricoid cartilage. With the introduction of prolonged intubation in neonates (mid 1960s), acquired SGS became the most frequent cause of laryngeal stenosis; unlike congenital SGS, it does not improve with time. Laryngeal reconstruction surgery evolved as a consequence of the need to manage these otherwise healthy but tracheotomized children. Ongoing innovations in neonatal care have gradually led to the salvage of premature and medically fragile infants in whom laryngeal pathology is often more severe, and in whom stenosis often involves not only the subglottis, but also the supraglottis or glottis-causing significant morbidity and mortality. The primary objective of intervention in these children is decannulation or preventing the need for tracheotomy. The aim of this article is to present a more detailed description of both congenital and acquired SGS, highlighting the essentials of diagnostic assessment and familiarizing the reader with contemporary management approaches.

    Lorier Gabriel


    Full Text Available OBJECTIVE: To analyze late clinical evolution after surgical treatment of children, with reparative and reconstructive techniques without annular support. METHODS: We evaluated 21 patients operated upon between 1975 and 1998. Age 4.67±3.44 years; 47.6% girls; mitral insufficiency 57.1% (12 cases, stenosis 28.6% (6 cases, and double lesion 14.3% (3 cases. The perfusion 43.10±9.50min, and ischemia time were 29.40±10.50min. The average clinical follow-up in mitral insufficiency was 41.52±53.61 months. In the stenosis group (4 patients was 46.39±32.02 months, and in the double lesion group (3 patients, 39.41±37.5 months. The echocardiographic follow-up was in mitral insufficiency 37.17±39.51 months, stenosis 42.61±30.59 months, and in the double lesion 39.41±37.51 months. RESULTS: Operative mortality was 9.5% (2 cases. No late deaths occurred. In the group with mitral insufficiency, 10 (83.3% patients were asymptomatic (p=0.04. The majorit y with mild reflux (p=0.002. In the follow-up of the stenosis group, all were in functional class I (NYHA; and the mean transvalve gradient varied between 8 and 12mmHg, average of 10.7mmHg. In the double lesion group, 1 patient was reoperated at 43 months. No endocarditis or thromboembolism were reported. CONCLUSION: Mitral stenosis repair has worse late results, related to the valve abnormalities and associated lesions. The correction of mitral insufficiency without annular support showed good long-term results.

  14. Usefulness of radionuclide angiocardiography in predicting stenotic mitral orifice area

    Burns, R.J.; Armitage, D.L.; Fountas, P.N.; Tremblay, P.C.; Druck, M.N.


    Fifteen patients with pure mitral stenosis (MS) underwent high-temporal-resolution radionuclide angiocardiography for calculation of the ratio of peak left ventricular (LV) filling rate divided by mean LV filling rate (filling ratio). Whereas LV filling normally occurs in 3 phases, in MS it is more uniform. Thus, in 13 patients the filling ratio was below the normal range of 2.21 to 2.88 (p less than 0.001). In 11 patients in atrial fibrillation, filling ratio divided by mean cardiac cycle length and by LV ejection fraction provided good correlation (r = 0.85) with modified Gorlin formula derived mitral area and excellent correlation with echocardiographic mitral area (r = 0.95). Significant MS can be detected using radionuclide angiocardiography to calculate filling ratio. In the absence of the confounding influence of atrial systole calculation of 0.14 (filling ratio divided by cardiac cycle length divided by LV ejection fraction) + 0.40 cm2 enables accurate prediction of mitral area (+/- 4%). Our data support the contention that the modified Gorlin formula, based on steady-state hemodynamics, provides less certain estimates of mitral area for patients with MS and atrial fibrillation, in whom echocardiography and radionuclide angiocardiography may be more accurate.

  15. Pregnancy and rheumatic diseases.

    Gayed, M; Gordon, C


    Pregnancy is an issue that should be discussed with all patients with rheumatic diseases who are in the reproductive age group. Infertility is rarely due to the disease but can be associated with cyclophosphamide therapy. Most rheumatic diseases that are well controlled prior to pregnancy do not deteriorate in pregnancy, providing that the patient continues with appropriate disease-modifying therapy. Some patients with inflammatory arthritis go in to remission during pregnancy. Patients with renal involvement may be at increased risk of disease flare. This needs to be distinguished from pre-eclampsia. Intrauterine growth restriction is more likely in patients with active systemic disease, hypertension, a history of thrombosis and renal involvement. Premature delivery may need to be planned to reduce the risks of stillbirth and can be associated with a variety of neonatal complications. Post-partum flare is common in all the rheumatic diseases.

  17. The evaluation of mitral heart disease by angiocardiography

    Lee, Yong Chul [National Medical Center, Seoul (Korea, Republic of)


    Left ventriculography with RAO projection gives many information about the states of mitral apparatus and of left ventricular function. The knowledge about these are very important to determination of performance, time and method of cardiac surgery in mitral valvular heart diseases. 20 patients of mitral valvular heart disease were studied with left ventriculographies in RAO projection which were taken before open heart surgery at department of radiology, National Medical Center during 1976 to June 1980, Comparing with operative findings and pathologic specimens. The results are as follows; 1. Poor motilities and irregularities of mitral valves which were visible above the fulcrum, and irregularities and severe retraction of the fornix during left ventricular systolic phases on left ventriculographies were compatible to the stage III by Sellers' classification of mitral valvular stenosis on operative findings. Mild degree of irregularities and restriction with smooth fornix suggested the stage I. The findings between these two, the stage II. 2. MI group showed left ventricular dilation without hypertrophy, MS group, no significant effect on LV, Ao group, enlargement with hypertrophy. 3. In Ms and MI groups, ejection fraction were relatively well preserved until grade I-II of NYHA Classification. But grade III-IV revealed decreased ejection fraction. E. F. was below 0.55 in 86% of grade III-IV. In Ao group, grade IV showed well preservation of E. F. 4. The pattern of left ventricular contraction demonstrated hypokinetic synesis or asynesis in 44.4% of grade IV, but was normal in all cases below grade III. Hyperkinetic synesis was visible in all Ao group. 5. Left ventriculography is essential to evaluation of mitral valve apparatus and LV function in mitral heart diseases before cardiac surgery.

  18. Transcatheter, valve-in-valve transapical aortic and mitral valve implantation, in a high risk patient with aortic and mitral prosthetic valve stenoses

    Harish Ramakrishna


    Full Text Available Transcatheter valve implantation continues to grow worldwide and has been used principally for the nonsurgical management of native aortic valvular disease-as a potentially less invasive method of valve replacement in high-risk and inoperable patients with severe aortic valve stenosis. Given the burden of valvular heart disease in the general population and the increasing numbers of patients who have had previous valve operations, we are now seeing a growing number of high-risk patients presenting with prosthetic valve stenosis, who are not potential surgical candidates. For this high-risk subset transcatheter valve delivery may be the only option. Here, we present an inoperable patient with severe, prosthetic valve aortic and mitral stenosis who was successfully treated with a trans catheter based approach, with a valve-in-valve implantation procedure of both aortic and mitral valves.

  19. [Rheumatic cardiopathy in children younger than 6 years of age].

    Vázquez-Antona, C; Calderón-Colmenero, J; Attié, F; Zabal, C; Buendía-Hernández, A; Díaz-Medina, L H; Bialkowski, J; García Arenal, F


    Most of the published papers on Rheumatic Fever (RF) have not included the younger population. We selected 211 cases of children with RF younger than 6 years of age from 9,471 clinical files from 1944 to 1982. These were followed retrospectively to identify the presence of rheumatic activity, subsequent attacks and penicillin profilaxis. From de 211 cases, 209 had carditis; 57% of them were girls and 43% boys. There were no previous infections of the upper respiratory tract in 36% of the patients. The number of cases with RF increased abruptly after 3 years of age and continued increasing until 5 years of age when 70.5% of the population had there first clinically recognized attack. Lesions were present in the mitral valve in 80% of the cases, in the aortic valve in 12%, in the tricuspid in 5% and in the pulmonary valve in 3%. The death rate during the first attack was 20% being refractory heart failure the main cause of death. Thirteen cases suffered rheumatic pneumonia, 9 of whom died (69.2%). 1) The incidence of acute rheumatic fever in children under 6 years of age has decreased with time. 2) The death rate as well as the valvular damage decreased with the parents cooperation with the treatment. 3) The changes in the clinical picture and the severity of valve sequelea may be due to penicillin profilaxis and the better understanding of the disease.

  20. Repeated mitral valve replacement in a patient with extensive annular calcification

    Kitamura Tadashi


    Full Text Available Abstract Background Mitral valve replacement in the presence of severe annular calcification is a technical challenge. Case report A 47-year-old lady who had undergone mitral and aortic valve replacement for rheumatic disease 27 years before presented with dyspnea. At reoperation, extensive mitral annular calcification was hindering the disc motion of the Starr-Edwards mitral prosthesis. The old prosthesis was removed and a St Jude Medical mechanical valve was implanted after thorough annular debridement. Postoperatively the patient developed paravalvular leak and hemolytic anemia, subsequently undergoing reoperation three days later. The mitral valve was replaced with an Edwards MIRA valve, with a bulkier sewing cuff, after more aggressive annular debridement. Although initially there was no paravalvular leak, it recurred five days later. The patient also developed a small cerebral hemorrhage. As the paravalvular leak and hemolytic anemia gradually worsened, the patient underwent reoperation 14 days later. A Carpentier-Edwards bioprosthetic valve with equine pericardial patches, one to cover the debrided calcified annulus, another as a collar around the prosthesis, was used to eliminate paravalvular leak. At 7 years postoperatively the patient is doing well without any evidence of paravalvular leak or structural valve deterioration. Conclusion Mitral valve replacement using a bioprosthesis with equine pericardial patches was useful to overcome recurrent paravalvular leak due to severe mitral annular calcification.

  3. Acute rheumatic fever and rheumatic heart disease in indigenous populations.

    Steer, Andrew C; Carapetis, Jonathan R


    Acute rheumatic fever and rheumatic heart disease are diseases of socioeconomic disadvantage. These diseases are common in developing countries and in Indigenous populations in industrialized countries. Clinicians who work with Indigenous populations need to maintain a high index of suspicion for the potential diagnosis of acute rheumatic fever, particularly in patients presenting with joint pain. Inexpensive medicines, such as aspirin, are the mainstay of symptomatic treatment of rheumatic fever; however, antiinflammatory treatment has no effect on the long-term rate of progression or severity of chronic valvular disease. The current focus of global efforts at prevention of rheumatic heart disease is on secondary prevention (regular administration of penicillin to prevent recurrent rheumatic fever), although primary prevention (timely treatment of streptococcal pharyngitis to prevent rheumatic fever) is also important in populations in which it is feasible.

  4. Mitral valve surgery for mitral regurgitation caused by Libman-Sacks endocarditis: a report of four cases and a systematic review of the literature

    Bijl Marc


    Full Text Available Abstract Libman-Sacks endocarditis of the mitral valve was first described by Libman and Sacks in 1924. Currently, the sterile verrucous vegetative lesions seen in Libman-Sacks endocarditis are regarded as a cardiac manifestation of both systemic lupus erythematosus (SLE and the antiphospholipid syndrome (APS. Although typically mild and asymptomatic, complications of Libman-Sacks endocarditis may include superimposed bacterial endocarditis, thromboembolic events, and severe valvular regurgitation and/or stenosis requiring surgery. In this study we report two cases of mitral valve repair and two cases of mitral valve replacement for mitral regurgitation (MR caused by Libman-Sacks endocarditis. In addition, we provide a systematic review of the English literature on mitral valve surgery for MR caused by Libman-Sacks endocarditis. This report shows that mitral valve repair is feasible and effective in young patients with relatively stable SLE and/or APS and only localized mitral valve abnormalities caused by Libman-Sacks endocarditis. Both clinical and echocardiographic follow-up after repair show excellent mid- and long-term results.

  5. Acute rheumatic fever and rheumatic heart disease.

    Carapetis, Jonathan R; Beaton, Andrea; Cunningham, Madeleine W; Guilherme, Luiza; Karthikeyan, Ganesan; Mayosi, Bongani M; Sable, Craig; Steer, Andrew; Wilson, Nigel; Wyber, Rosemary; Zühlke, Liesl


    Acute rheumatic fever (ARF) is the result of an autoimmune response to pharyngitis caused by infection with group A Streptococcus. The long-term damage to cardiac valves caused by ARF, which can result from a single severe episode or from multiple recurrent episodes of the illness, is known as rheumatic heart disease (RHD) and is a notable cause of morbidity and mortality in resource-poor settings around the world. Although our understanding of disease pathogenesis has advanced in recent years, this has not led to dramatic improvements in diagnostic approaches, which are still reliant on clinical features using the Jones Criteria, or treatment practices. Indeed, penicillin has been the mainstay of treatment for decades and there is no other treatment that has been proven to alter the likelihood or the severity of RHD after an episode of ARF. Recent advances - including the use of echocardiographic diagnosis in those with ARF and in screening for early detection of RHD, progress in developing group A streptococcal vaccines and an increased focus on the lived experience of those with RHD and the need to improve quality of life - give cause for optimism that progress will be made in coming years against this neglected disease that affects populations around the world, but is a particular issue for those living in poverty.

  6. Percutaneous mitral valve repair.

    Gillinov, A Marc; Liddicoat, John R


    Surgical mitral valve repair is the procedure of choice to treat mitral regurgitation of all etiologies. Whereas annuloplasty is the cornerstone of mitral valve repair, a variety of other surgical techniques are utilized to correct dysfunction of the leaflets and subvalvular apparatus; in most cases, surgical repair entails application of multiple repair techniques in each patient. Preclinical studies and early human experience have demonstrated that some of these surgical repair techniques can be performed using percutaneous approaches. Specifically, there has been great progress in the development of novel technology to facilitate percutaneous annuloplasty and percutaneous edge-to-edge repair. The objectives of this report were to (1) discuss the surgical foundations for these percutaneous approaches; (2) review device design and experimental and clinical results of percutaneous valve repair; and (3) address future directions, including the key challenges of patient selection and clinical trial design.

  7. Oncohematologic diseases and rheumatic disorders

    Nelson Hamerschlak


    Full Text Available Mielodysplasia, leukemia, lynfoma and multiple myeloma are themain oncohematologic diseases related to rheumatic manifestations.In multiple myeloma the pain manifestation is caused by fracturefrom bone lesions as a direct consequence of the disease, not beingan associateda true rheumatic manifestation. An interesting aspectof this subject is that many rheumatic manifestations occur beforehematologic diseases as, for example, lymphomas. Therefore we cansay that some rheumatic diseases are associated to a greater riskof oncohematologic diseases. On the other hand, oncohematologicdiseases can present rheumatic manifestations in articulations,muscles and vessels. Theses cases are usually interpreted as paraneoplasics.This chapter is divided in three parts: oncohematologicdiseases with rheumatic manifestations; rheumatic diseases thatpresent greater risk of oncohematologic pathologies; and the mainrheumatic manifestations of oncohematologic diseases.

  8. Understanding rheumatic fever.

    Azevedo, Pedro Ming; Pereira, Rosa Rodrigues; Guilherme, Luiza


    Through a comprehensive review of the recent findings on rheumatic fever, we intend to propose a new physiopathologic model for this disease. A Medline search was performed for all articles containing the terms rheumatic fever or rheumatic heart disease in title or abstract from 1970 to 2011. Best evidence qualitative technique was used to select the most relevant. The scientific interest on rheumatic fever has notably diminished throughout the twentieth century as evidenced by the comparison of the proportion of articles in which RF was a subject in 1950 (0.26%) and today (0.03%) [Pubmed]. However, RF remains a major medical and social problem in the developing world and in the so-called hotspots, where it still causes around 500.000 deaths each year, not too different from the pre-antibiotic era. The role of genetic factors in RF susceptibility is discussed. Familiar aggregation, similarity of disease patterns between siblings, identical twin, and HLA correlation studies are evidence for a genetic influence on RF susceptibility. The suspect-involved genes fall mainly into those capable of immunologic mediation. Molecular mimicry explains the triggering of RF, but an intense and sustained inflammation is needed to cause sequels. Also, RF patients vary greatly in terms of symptoms. It is likely that a genetic background directing immune response towards a predominantly Th1 or Th2 pattern contributes to these features. The recent findings on rheumatic fever provide important insight on its physiopathology that helps understanding this prototype post-infectious autoimmune disease giving insights on other autoimmune conditions.

  9. Diverticulum of the mitral valve, a rare cause of mitral regurgitation.

    Soo, Alan


    Non-infective mitral valve diverticulum is extremely rare. We present a case of intraoperatively diagnosed mitral valve diverticulum of a 69-year-old man presenting with mitral regurgitation who was successfully treated with mitral valve replacement.

  10. Right ventricular function in patients with mitral valve disease; Evaluation by radionuclide blood pool scan

    Hiraki, Yoshio; Shimizu, Mitsuharu; Noriyasu, Toshiaki; Nakagawa, Tomio; Aono, Kaname; Yanagi, Hidekiyo; Seno, Yoshimasa; Teramoto, Shigeru; Nagaya, Isao (Okayama Univ. (Japan). School of Medicine)


    Right ventricular function was studied in 13 patients with mitral valve stenosis (MS), 10 patients with mitral valve regurgitation (MR) and 10 patients after mitral valve replacement (MVR) with radionuclide blood pool scan. In MS, right ventricular end-diastolic and end-systolic volumes were larger than MVR. In MR, right ventricular ejection fraction (RVEF) was smaller and right ventricular end-systolic volume was larger than MVR. In both MS and MR, there was no significant linear correlation between RVEF and mean pulmonary arterial pressure (mPAP) at rest, but during exercise RVEF of patients with elevated mPAP decreased more than that of patients with normal mPAP. RVEF in patients with MS and MR was significantly decreased during exercise, while that in patients after MVR showed no significant change. Radionuclide blood pool scan seems to be useful for the evaluation of right ventricular function in mitral valve disease. (author).

  11. Perioperative management of patient with Bombay blood group undergoing mitral valve replacement.

    Priye, Shio; Sathyanarayan, J; Shivaprakash, S; Reddy, Durgaprasad


    Bombay red blood cell phenotype is an extremely rare blood type for which patients can receive only autologous or Bombay phenotype red blood cells. We report a case of stenotic mitral valve with Bombay phenotype who underwent minimal invasive right lateral thoracotomy for the replacement of the mitral valve. A male patient from Bangladesh presented to the hospital with New York Heart Association III symptoms. His medical evaluation revealed severe mitral valve stenosis and mild aortic valve regurgitation. The patient received erythropoietin, intravenous iron succinate and folic acid tablets. Autologous blood transfusion was carried out. The mitral valve was replaced with a prosthetic valve successfully. After weaning off from cardiopulmonary bypass, heparinisation was corrected with protamine. Post-operatively, the patient received autologous red blood cells. The patient recovered after 1-day of inotropic support with adrenaline and milrinone, and diuretics and was discharged on the 5(th) post-operative day.

    Bruschi, Giuseppe; De Marco, Federico; Oreglia, Jacopo; Colombo, Paola; Fratto, Pasquale; Lullo, Francesca; Paino, Roberto; Frigerio, Maria; Martinelli, Luigi; Klugmann, Silvio


    Concerns exist in the field of transcatheter aortic valve implantation regarding the treatment of patients with mechanical mitral valve for possible interference between the percutaneous aortic valve and the mechanical mitral prosthesis. We report our experience with percutaneous aortic valve implantation in 4 patients with severe aortic stenosis, previously operated on for mitral valve replacement with a mechanical prosthesis. All patients underwent uneventful percutaneous retrograde CoreValve implantation (CoreValve Inc, Irvine, CA). No deformation of the nitinol tubing of the prostheses (ie, neither distortion nor malfunction of the mechanical valve in the mitral position) occurred in any of the patients. All patients are alive and asymptomatic at a mean follow-up of 171 days.

    Mehrnoush Toufan


    Full Text Available A 29-year old female patient was referred to our hospital for evaluation of dyspnea NYHA class I which begun from several months ago. The only abnormal sign found on physical examination was a grade 2/6 systolic murmur at the apex position without radiation. Echocardiography revealed normal left and right ventricular sizes and systolic function, and only one papillary muscle in left ventricular (LV cavity which all chordae tendineae inserted into that muscle. The mitral valve orifice was eccentrically located at the lateral side with mild to moderate mitral regurgitation but without significant mitral stenosis. No other congenital heart anomalies were identified. Thus, the final diagnosis was isolated parachute mitral valve (IPMV. She was one of the very rare IPMV cases have ever been reported in adults

  16. Homoenxerto mitral: uma realidade

    Francisco Diniz Affonso da COSTA


    Full Text Available Fundamentos: A utilização de homoenxertos valvares aórticos criopreservados está associada a excelente qualidade de vida, com baixa morbidade e durabilidade satisfatória. Espera-se obter resultados semelhantes em posição mitral com o emprego de homoenxertos mitrais criopreservados. Objetivo: Avaliar os resultados imediatos e a curto prazo da substituição da valva mitral por homoenxerto mitral criopreservado. Casuística e Métodos: De julho/97 a fevereiro/98, 8 pacientes com média de idades de 40,3 ± 6,2 anos foram submetidos a substituição da valva mitral por homoenxerto mitral criopreservado. A técnica de implante consistiu de fixação látero-lateral dos músculos papilares, sutura anular contínua e anuloplastia com anel de Carpentier. Antes da alta, todos os pacientes realizaram ecocardiografia bidimensional com Doppler para análise da função valvar e ventricular. Os pacientes foram solicitados a retornar no primeiro mês e, subseqüentemente, a cada três meses de pós-operatório, para controles clínico e ecocardiográfico tardio. Resultados: Houve um óbito hospitalar de causa não relacionada ao enxerto. A avaliação ecocardiográfica antes da alta hospitalar demonstrou média das áreas valvares de 3,1 ± 0,6 cm2 e média dos gradientes médios de 3,5 ± 1,6 mmHg. A insuficiência valvar foi quantificada como inexistente ou trivial em 4 casos e leve em 3. A fração de ejeção de 57 ± 7% no pré-operatório foi adequadamente preservada no pós-operatório (62 ± 6%. Os níveis de hipertensão pulmonar regrediram significativamente de 87 ± 15 mmHg no pré-operatório para 48 ± 12 mmHg no pós-operatório. Houve também redução do tamanho da cavidade atrial esquerda de 61 ± 10 mm para 53 ± 7 mm. Nenhum paciente foi perdido do acompanhamento tardio. Após um tempo médio de seguimento de 4,1 ± 2,5 meses, os pacientes encontram-se funcionalmente bem e sem complicações pós-operatórias. O estudo ecocardiogr

    Villalba, Claudia N; Mouratian, Mariela; Lafuente, María V; Barretta, Jorge; Capelli, Horacio


    Recurrent wheezing is a very common clinical ailment throughout infancy and childhood. The most common diagnosis in children with wheezing is asthma. However, some other causes should be considered in the differential diagnosis such as a congenital cardiac defect. We present a case of a four year old boy presenting with recurrent wheezing who was referred to our institution for cardiac evaluation. Severe mitral stenosis secondary to an anomalous mitral arcade was diagnosed by physical examination, chest X-ray, electrocardiogram and mainly transthoracic and transesophageal echocardiography. Anomalous mitral arcade is a rare congenital malformation of the mitral tensor apparatus which comprises the chordae tendineae and papillary muscles. This abnormal anatomy leads to increased filling pressure of the left ventricle, a retrograde post capillary pulmonary hypertension and interstitial aedema. The patient was referred to cardiac surgery and underwent a successful procedure with complete removal of the obstructive mitral lesion.

    Previous studies indicate that compared with physical examination, Doppler echocardiography identifies a larger number of cases of rheumatic heart disease in apparently healthy individuals. To determine the prevalence of rheumatic heart disease among students in a public school of Belo Horizonte by clinical evaluation and Doppler echocardiography. This was a cross-sectional study conducted with 267 randomly selected school students aged between 6 and 16 years. students underwent anamnesis and physical examination with the purpose of establishing criteria for the diagnosis of rheumatic fever. They were all subjected to Doppler echocardiography using a portable machine. Those who exhibited nonphysiological mitral regurgitation (MR) and/or aortic regurgitation (AR) were referred to the Doppler echocardiography laboratory of the Hospital das Clínicas of the Universidade Federal of Minas Gerais (HC-UFMG) to undergo a second Doppler echocardiography examination. According to the findings, the cases of rheumatic heart disease were classified as definitive, probable, or possible. Of the 267 students, 1 (0.37%) had a clinical history compatible with the diagnosis of acute rheumatic fever (ARF) and portable Doppler echocardiography indicated nonphysiological MR and/or AR in 25 (9.4%). Of these, 16 (6%) underwent Doppler echocardiography at HC-UFMG. The results showed definitive rheumatic heart disease in 1 student, probable rheumatic heart disease in 3 students, and possible rheumatic heart disease in 1 student. In the population under study, the prevalence of cases compatible with rheumatic involvement was 5 times higher on Doppler echocardiography (18.7/1000; 95% CI 6.9/1000-41.0/1000) than on clinical evaluation (3.7/1000-95% CI)

    Reichart, B; Kemkes, B M; Klinner, W; Kreuzer, E; Becker, H M; Harrington, O B; Crosby, V G; Wolf, R Y


    This is an account on combined procedures in 124 patients suffering from arteriosclerotic vessel disease. In order to judge the proceedings and the results the patients were divided up into two groups. in 15 patients (group I) a carotid endarterectomy combined with an aorto-coronary bypass operation was performed; once a subclavian artery stenosis was resected at the same time. One patient of that group died after 31 days (7%). In group II 108 heart valve operations were performed together with a coronary artery revascularisation. Early and late mortality divided up as follows: aortic stenosis 6/44 (14%) respectively 2/44 (5%); aortic insufficiency 1/14 (7%) resp. 0; combined aortic disease 1/8 )13%) resp. 0; mitral stenosis 1/11 (9%) resp. 0; mitral insufficiency 6/26 (23%) resp. 2/26 (8%); combined mitral valve disease 1/2 (50%) resp. 0; three times both valves (aorta, mitral) were replaced without mortality. In our opinion combined procedures, resection of supraaortic artery stenosis respectively cardiac valve operations and aorto-coronary bypass are indicated especially since the functional long-term results are excellent. Though one should consider the high operative risk in patients with mitral insufficiency and combined mitral valve disease.

  1. Acute Rheumatic Fever: An Evidence-Based Approach To Diagnosis And Initial Management.

    Khanna, Kajal; Liu, Deborah R


    Acute rheumatic fever is an inflammatory reaction involving the joints, heart, and nervous system that occurs after a group A streptococcal infection. It typically presents as a febrile illness with clinical manifestations that could include arthritis, carditis, skin lesions, or abnormal movements. Of these, the cardiac manifestations of acute rheumatic fever are most concerning, as children may present in acute heart failure and may go on to develop valvular insufficiency or stenosis. Because this is a rare presentation to emergency departments in developed countries, it is crucial for clinicians to keep a broad differential when presented with clinical presentations suspicious for acute rheumatic fever. This issue focuses on the clinical evaluation and treatment of patients with acute rheumatic fever by offering a thorough review of the literature on diagnosis and recommendations on appropriate treatment.

  2. Late thrombosis of a mitral bioprosthetic valve with associated massive left atrial thrombus

    Preetham R Muskula


    Full Text Available An 84-year-old man presented 5 years after bioprosthetic mitral valve replacement with three months of worsening dyspnea on exertion. A new mitral stenosis murmur was noted on physical examination, and an electrocardiogram revealed newly recognized atrial fibrillation. Severe mitral stenosis (mean gradient = 13 mmHg was confirmed by transthoracic echocardiography. Transesophageal echocardiography revealed markedly thickened mitral bioprosthetic leaflets with limited mobility, and a massive left atrial thrombus (>4 cm in diameter (Fig. 1A, B, C, D and Videos 1, 2, 3 and 4. Intravenous heparin was initiated, and 5 days later, he was taken to the operating room for planned redo mitral valve replacement and left atrial thrombus extraction. Intraoperative transesophageal echocardiography revealed near-complete resolution of the bioprosthetic leaflet thickening, and a mean mitral gradient of only 3 mmHg (Fig. 2A, B, C and Videos 5, 6 and 7. The patient underwent resection of the massive left atrial thrombus (Fig. 2D but did not require redo mitral valve replacement. He was initiated on heparin (and transitioned to warfarin early in the post-operative period, with complete resolution of dyspnea on exertion at 3-month follow-up. Bioprosthetic valve thrombosis is increasingly recognized as a cause of early prosthetic valve dysfunction (1, 2. This case illustrates that bioprosthetic valve thrombosis may occur years after valve replacement; therefore, any deterioration in a patient’s clinical status (new-onset dyspnea, heart failure or atrial fibrillation warrants a thorough evaluation of the bioprosthetic valve with transesophageal echocardiography. In this case, initiation of anticoagulation obviated the need for redo mitral valve replacement.

  3. Osteoporosis and rheumatic diseases

    N. Maruotti


    Full Text Available Numerous rheumatic diseases, including rheumatoid arthritis, juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, systemic lupus erythematosus, systemic sclerosis, dermatomyositis/polymyositis and vasculitis are characterized by osteoporosis and fragility fractures. Inflammatory cytokines, glucocorticoid treatment, immobilization and reduced physical activity due to painful joints and muscle weakness are considered the main risk factors that cause low body mass density values in these diseases. Emerging evidence highlights the role of inflammatory cytokines, such as tumor necrosis factor (TNF-α, interleukin (IL-1, IL-6, IL-7 and IL-17, in the regulation of the bone homeostasis. In fact, chronic inflammation is often characterized by an imbalance between bone formation and bone resorption with a net prevalence of osteoclastogenesis, which is an important determinant of bone loss in rheumatic diseases.

  4. Massive left atrial and interatrial septal calcification after mitral valve replacement

    Yu-Shen Lin; Feng-Chun Tsai; Pao-Hsien Chu


    @@ Massive calcification of left atrium is an uncommon complication of long-standing rheumatic valvular disease, and is most often observed in patients with a previous operation on mitral valve.1 Most patients have experienced symptoms for more than 15 years.2 Massive calcification of the left atrium generally spared the interatrial septum in the previous studies.4 However, to our knowledge, fewer than five cases have presented as full left atrial calcification (Table).

  5. Mitral Valve Prolapse in Pregnancy

    Shi-Min Yuan

    Full Text Available Abstract Mitral valve prolapse is a benign condition. Mitral regurgitation is only complicated in patients with severe mitral valve prolapse. Women with mitral valve prolapse in the absence of other cardiovascular disorders tolerate pregnancy well and do not develop remarkable cardiac complications. Nevertheless, serious complications of mitral valve prolapse, including arrhythmia, infective endocarditis and cerebral ischemic events, can be present in pregnancy. Debates remain with regard to the use of prophylactic antibiotics and β-blockers in the pregnant women with mitral valve prolapse. The prognosis of the pregnant patients might be closely related to the pathological and (or functional changes of the mitral valve. Non-myxomatous mitral valve prolapse poses no or little obstetric risks in terms of pregnancy, labor and neonatal complications; whereas myxomatous mitral valve prolapse is a major etiology of valvular heart disease in women of childbearing age. In the pregnant patients with mitral valve prolapse progressing into major complications, surgical interventions are considered. Medicinal treatment of such patients with β-blockers should be a concern for the fetal safety.

  9. Modeling the Mitral Valve

    Kaiser, Alexander


    The mitral valve is one of four valves in the human heart. The valve opens to allow oxygenated blood from the lungs to fill the left ventricle, and closes when the ventricle contracts to prevent backflow. The valve is composed of two fibrous leaflets which hang from a ring. These leaflets are supported like a parachute by a system of strings called chordae tendineae. In this talk, I will describe a new computational model of the mitral valve. To generate geometry, general information comes from classical anatomy texts and the author's dissection of porcine hearts. An MRI image of a human heart is used to locate the tips of the papillary muscles, which anchor the chordae tendineae, in relation to the mitral ring. The initial configurations of the valve leaflets and chordae tendineae are found by solving solving an equilibrium elasticity problem. The valve is then simulated in fluid (blood) using the immersed boundary method over multiple heart cycles in a model valve tester. We aim to identify features and mechanisms that influence or control valve function. Support from National Science Foundation, Graduate Research Fellowship Program, Grant DGE 1342536.

  11. Mitral valve replacement with preservation of subvalvular apparatus in a patient with familial dextrocardia and situs solitus.

    Khan, Junaid Fayyaz; Khan, Imran; Khan, Kamran


    Familial dextrocardia with situs solitus is extremely rare entity. Dextrocardia offers a difficult situation to surgeon. A different strategy for cannulation and approach to the left atrium has to be followed. Surgery in such settings has rarely been reported. We present the case of a patient with dextrocardia and situs solitus wherein a left sided approach was adopted for a better exposure of the valve. The patient had a rheumatic regurgitant mitral valve with ruptured chordae to anterior mitral leaflet. Since the valve was severely thickened, it was replaced rather than repaired. The left sided approach provided good exposure of the valve.

  12. Is Mitral Annular Calcification Associated With Atherosclerotic Risk Factors and Severity and Complexity of Coronary Artery Disease?

    We assessed the association of mitral annular calcification (MAC) with atherosclerotic risk factors and severity and complexity of coronary artery disease (CAD). Cardiac catheterization reports and electronic medical records from 2010 to 2011 were retrospectively reviewed. A total of 481 patients were divided into 2 groups: MAC present (209) and MAC absent (272). All major cardiovascular risk factors, comorbidities, and coronary lesion characteristics were included. On linear regression analysis, age (P = .001, β 1.12) and female gender (P = .031, β 0.50) were the independent predictors of MAC. Mitral annular calcification was not independently associated with the presence of lesions with >70% stenosis (P = .283), number of obstructive vessels (P = .469), lesions with 50% to 70% stenosis (P = .458), and Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery score (P = .479). Mitral annular calcification is probably a benign marker of age-related degenerative changes in the heart independent of the severity and complexity of CAD.

  13. Ross-Kabbani Operation in an Infant with Mitral Valve Dysplasia

    Carlo Pace Napoleone


    Full Text Available Background. Mitral valve replacement can be very difficult to obtain in infants because the valve annulus diameter can be smaller than the available prosthesis. Case Report. We describe the case of a 2-month-old female weighing 3.5 kg affected by mitral valve dysplasia leading to severe valve stenosis. Despite full medication, the clinical conditions were critical and surgery was undertaken. The mitral valve was unsuitable for repair and the orifice of mitral anulus was 12 mm, too small for a mechanical prosthesis. Therefore, a Ross-Kabbani operation was undertaken, replacing the mitral valve with the pulmonary autograft and reconstructing the right ventricular outflow tract with an etherograft. Results. The postoperative course was uneventful and the clinical conditions are good at 4-month follow-up. Conclusion. The Ross-Kabbani operation can be an interesting alternative to mitral valve replacement in infants when valve repair is not achievable and there is little space for an intra-annular mechanical prosthesis implant.

  14. Echocardiographic evaluation of mitral geometry in functional mitral regurgitation

    Maleki Majid


    Full Text Available Abstract Objectives We sought to evaluate the geometric changes of the mitral leaflets, local and global LV remodeling in patients with left ventricular dysfunction and varying degrees of Functional mitral regurgitation (FMR. Background Functional mitral regurgitation (FMR occurs as a consequence of systolic left ventricular (LV dysfunction caused by ischemic or nonischemic cardiomyopathy. Mitral valve repair in ischemic MR is one of the most controversial topic in surgery and proper repairing requires an understanding of its mechanisms, as the exact mechanism of FMR are not well defined. Methods 136 consecutive patients mean age of 55 with systolic LV dysfunction and FMR underwent complete echocardiography and after assessing MR severity, LV volumes, Ejection Fraction, LV sphericity index, C-Septal distance, Mitral valve annulus, Interpapillary distance, Tenting distance and Tenting area were obtained. Results There was significant association between MR severity and echocardiogarphic indices (all p values Mitral annular dimensions and area, C-septal distance and sphericity index, although greater in patients with severe regurgitation, did not significantly contribute to FMR severity. Conclusion Degree of LV enlargement and dysfunction were not primary determinants of FMR severity, therefore local LV remodeling and mitral valve apparatus deformation are the strongest predictors of functional MR severity.

  15. Clinical assessment and echocardiography follow-up results of the children with acute rheumatic fever

    Ahmet Basturk


    Full Text Available Acute rheumatic fever (ARF is an inflammatory collagenous tissue disease which shows its cardinal signs in joints, heart, skin and nervous system while affecting whole connective tissue system more or less. This study was conducted in order to investigate the clinical pattern and severity of ARF, echocardiographic findings and the course of the patients with heart valve involvement by studying the clinical and laboratory aspects of the patients diagnosed with ARF according to updated Jones criteria. The study included 214 patients diagnosed with ARF for the first time between January 2005 and May 2008. All patients were scanned with doppler echocardiography (ECHO between certain intervals. Severity of carditis was grouped into 3 groups of mild, moderate and severe. The frequency of carditis was 57.9%, arthritis was 73.4%, chorea was 11.7% and erythema marginatum was 0.9% but no subcutaneous nodules. Recovery was observed in 22% of the cases of isolated aortic insufficiency (AI, 50% of the cases with isolated mitral insufficiency (MI and 80% of the cases with mitral and aortic insufficiencies together (MI+AI. Recovery in isolated MI was significantly much more than recovery in isolated AI. However, recovery in AI was significantly much more than in MI in cases of mitral and aortic insufficiencies together. In conclusion, ARF is a cause of acquired and preventable heart disease and it can be reversed through right diagnosis and appropriate treatment. Isolated mitral insufficiency, isolated aortic insufficiency and both mitral and aortic insufficiency are observed during a valvular disease. Remission among valvular diseases are most commonly in those with mitral insufficiency and remissions in both mitral and aortic insufficiency occur most commonly in aortic ones. Regular prophylaxis is the key element for long term prevention of patients with ARF.

  16. Tricuspid regurgitation after successful mitral valve surgery.

    Katsi, Vasiliki; Raftopoulos, Leonidas; Aggeli, Constantina; Vlasseros, Ioannis; Felekos, Ioannis; Tousoulis, Dimitrios; Stefanadis, Christodoulos; Kallikazaros, Ioannis


    The tricuspid valve (TV) is inseparably connected with the mitral valve (MV) in terms of function. Any pathophysiological condition concerning the MV is potentially a threat for the normal function of the TV as well. One of the most challenging cases is functional tricuspid regurgitation (TR) after surgical MV correction. In the past, TR was considered to progressively revert with time after left-sided valve restoration. Nevertheless, more recent studies showed that TR could develop and evolve postoperatively over time, as well as being closely associated with a poorer prognosis in terms of morbidity and mortality. Pressure and volume overload are usually the underlying pathophysiological mechanisms; structural alterations, like tricuspid annulus dilatation, increased leaflet tethering and right ventricular remodelling are almost always present when regurgitation develops. The most important risk factors associated with a higher probability of late TR development involve the elderly, female gender, larger left atrial size, atrial fibrillation, right chamber dilatation, higher pulmonary artery systolic pressures, longer times from the onset of MV disease to surgery, history of rheumatic heart disease, ischaemic heart disease and prosthetic valve malfunction. The time of TR manifestation can be up to 10 years or more after an MV surgery. Echocardiography, including the novel 3D Echo techniques, is crucial in the early diagnosis and prognosis of future TV disease development. Appropriate surgical technique and timing still need to be clarified.

  18. Mitral valve replacement via right thoracotomy approach for prevention of mediastinitis in a female patient with long-term uncontrolled diabetes mellitus: a case report

    Fujiwara Hiroshi


    Full Text Available Abstract A 76-year-old woman with a history of percutaneous transvenous mitral commissurotomy and repeated hospital admissions due to heart failure was referred for an operation for severe mitral valve stenosis. She presented with hypertension, hyperlipidemia and cerebral infarction with stenosis of right internal carotid artery, retinopathy, neuropathy and nephropathy caused by long-term uncontrolled diabetes mellitus, hemoglobin A1c of 9.4%, and New York Heart Association (NYHA functional classification of 3/4. Echocardiography revealed severe mitral valve stenosis with mitral valve area of 0.6 cm2, moderate tricuspid valve regurgitation, and dilatation of the left atrium. Taking into consideration the NYHA functional classification and severe mitral valve stenosis, an immediate surgical intervention designed to prevent mediastinitis was performed. The approach was via the right 4th thoracotomy, as conventional sternotomy would raise the risk of mediastinitis. Postoperative antibiotics were administered intravenously for 2 days, and signs of infection were not recognized. In patients with long-term uncontrolled diabetes mellitus, mid-line sternotomy can easily cause mediastinitis. The choice of operative approach plays an important role in preventing this complication. In this report, the importance of the conventional right thoracotomy for prevention for mediastinitis is reviewed.

  20. [Skin changes in rheumatic diseases].

    Dobrić, Ivan


    The Intruduction includes those eflorescences that might be useful for diagnostics in rheumatology. Further in the text we have described four groups of rheumatic disorders. The first group: rheumatic diseases (lupus erythematosus, dermatomyositis, systemic scleroderma, the mixed connective tissue disease, allergic vasculitis, polyarteritis) which are the most common from the dermatological point of view. The second group: rheumatic diseases (Wegener's granulomatosis, rheumatoid arthritis, Sjögren, Reiter and Behçet syndrome and Kawasaki's disease) which are rarely of interest to our dermatologists. In this group there is also psoriatic arthritis, which is not rare in dermatology but its diagnostics and treatment belong to rheumatologists' field of expertise. The third group: infections (rheumatic fever, diseminated gonococcal infection, subacute bacterial endocarditis, Lyme disesease). The fourth group: metabolic disorders (gout). The diseases of the first group are described completely. In the second, third and fourth group of the diseases we have included only skin changes.

  1. Atypical recurrence of rheumatic chorea

    Gunjan Pankaj Kumar


    Full Text Available Syndenhams Chorea in acute rheumatic fever is reported to occur in 20-30% of patients. It is usually late onset, occurring upto 6 months after acute infection but may occasionally be present as presenting symptom of rheumatic fever. It is a self-limiting condition with spontaneous remission lasting from 1 week to 6 months. The risk of recurrence is present in 1st 1-2 years in about 20% of cases. Most of children (two thirds with rheumatic fever are of school age (5-15 years of age. It is common in India and the incidence has not shown the declining trends seen in the developing countries. We report the clinical findings, investigations and the course of clinical development of a 14-year-old girl, who presented with Rheumatic chorea which recurred 3 years after the initial episode.

  2. Rheumatic Fever Programme in Samoa.

    Viali, Satupaitea; Saena, Puleiala; Futi, Vailogoua


    Rheumatic fever is very common in Samoa. The following paper describes the Rheumatic Fever Programme in Samoa and looks at the incidence of acute rheumatic fever (ARF) and rheumatic heart disease (RHD). The incidence of ARF has decreased to 30 per 100,000 in 2005, 12.8 per 100,000 in 2007, 7.3 per 100,000 in 2008, and 9.5 per 100,000 in 2009. The incidence of RHD has decreased to 40.2 per 100,000 in 2007, 34 per 100,000 in 2008, and 31.8 per 100,000 in 2009. Cardiac surgery in New Zealand is expensive, but is cheaper to perform in Samoa. RHD screening with echocardiogram at schools may be the best way to reduce the burden and suffering from RHD.

  3. Rapidly progressing, massive mitral annular calcification. Occurrence in a patient with chronic renal failure.

    Depace, N L; Rohrer, A H; Kotler, M N; Brezin, J H; Parry, W R


    Calcification of the mitral annulus developed in a patient while undergoing dialysis. The rapid onset of events corresponded to the onset of end-stage renal failure and uncontrolled secondary hyperparathyroidism. Sequential echocardiograms verified the progression of calcification of the annulus as well as the valve. A new systolic and diastolic murmur and reduced valve orifice on two-dimensional echocardiography suggested acquired nonrheumatic mitral stenosis and insufficiency. We propose that metastatic calcium deposition rather than long-term hypertensive and degenerative effects was the predominant mechanism for massive calcification of the annulus and valve. It is suggested that M-mode echocardiography be used sequentially to follow both the occurrence and progression of calcification of the mitral annulus or valve in patients with chronic renal failure, secondary hyperparathyroidism, or both.

  4. Seamless reconstruction of mitral leaflet and chordae with one piece of pericardium.

    Ito, Toshiaki; Maekawa, Atsuo; Aoki, Masakazu; Hoshino, Satoshi; Hayashi, Yasunari; Sawaki, Sadanari; Yanagisawa, Junji; Tokoro, Masayoshi


    Mitral valve repair is challenging when enough pliable mitral leaflets and chordae are not left intact because of extensive infective endocarditis or chronic sclerotic degeneration. For those cases, we developed a simple method to reconstruct defective leaflets and chordae en bloc with a piece of pericardium, and the mid-term results were evaluated. From January 2009 to November 2013, 25 patients with the mean age of 63 (range 20-88) years underwent this operation. The causes of mitral regurgitation were infective endocarditis in 8, sclerotic degeneration in 8, leaflet dehiscence of previous repair in 2, mitral annular calcification in 3, rheumatic in 2 and congenital in 2. After complete debridement of infected or consolidated tissue, we reconstructed defective mitral leaflets and chordae en bloc with a piece of glutaraldehyde-treated autologous pericardium. To substitute posterior leaflet and chordae, the pericardium was trimmed into a narrow pentagonal shape. The pointed end was attached directly to the corresponding papillary muscle, basal side edges to remnant leaflets on both sides, and the base to the annulus. For anterior leaflet, the pericardium was trimmed into a triangular shape if the lesion was confined in the left or right half or into a double-triangle shape if the lesion involved whole anterior leaflet. The summit of triangle was fixed to corresponding papillary muscle, and the base to remnant anterior leaflet, thus reconstructing coaptation zone and chordae seamlessly. There was no hospital death, and mitral regurgitation at discharge was none or trivial in all patients. During 1-59 months (mean 12.7) of complete follow-up, death, infection or hemolysis was not observed. In one patient, mitral regurgitation recurred 8 months postoperatively because the fixation suture of the pericardium to the papillary muscle broke. The valve was re-repaired with re-attaching the leg of the pericardium. Regurgitation was less than moderate in all other patients

    Full Text Available Rheumatic heart disease is a one of the very common heart problem commonly prevalent among the children of developing countries, may occur in adults in their fourties also, if undiagnosed in early ages, similar in symptoms to ‘rheumatism’ but quite difficult to diagnose or are often misdiagnosed. The main objective of this article is to make acquainted about the disease and its further consequences, since initially it appears to be just a simple general fever but may prove deadly if undiagnosed or misdiagnosed leading to severe heart valve damage and consequent complications. The methods involved in the case include bilateral Femoral Embolectomy (BFE, Fasciotomy and Balloon Mitral Valvotomy (BMV. Through this case study an attempt has been made by the authors to make the people especially from the medical and related field, well acquainted about this deadly, silent, heart disease and its consequent complications.

  6. Historical aspects of rheumatic fever.

    Steer, Andrew C


    Few diseases have experienced such a remarkable change in their epidemiology over the past century, without the influence of a vaccine, than rheumatic fever. Rheumatic fever has all but disappeared from industrialised countries after being a frequent problem in the 1940s and 1950s. That the disease still occurs at high incidence in resource limited settings and in Indigenous populations in industrialised countries, particularly in Australia and New Zealand, is an indication of the profound effect of socio-economic factors on the disease. Although there have been major changes in the epidemiology of rheumatic fever, diagnosis remains reliant on careful clinical judgement and management is remarkably similar to that 50 years ago. Over the past decade, increasing attention has been given to rheumatic fever and rheumatic heart disease as public health issues, including in Australia and particularly in New Zealand, as well as in selected low and middle income countries. Perhaps the greatest hope for public health control of rheumatic fever is the development of a vaccine against Streptococcus pyogenes, and there are encouraging initiatives in this area. However, an effective vaccine is some time away and in the meantime public health efforts need to focus on effective translation of the known evidence around primary and secondary prophylaxis into policy and practice.

  7. [Long-term results of closed mitral commissurotomy--comparative study of closed mitral commissurotomy (CMC), open mitral commissurotomy (OMC) and mitral valve replacement (MVR)].

    Suzuki, S; Kondo, J; Imoto, K; Kajiwara, H; Tobe, M; Sakamoto, A; Isoda, S; Yamazaki, I; Noishiki, Y; Matsumoto, A


    As the technique of open heart surgery has improved, CMC has been abandoned in favor of OMC and MVR. We evaluated and compared the results of CMC, OMC and MVR. METHOD. Between 1965 and 1978, 141 patients with mitral stenosis (MS) underwent CMC, and late follow-up obtained in 117 (83%) of them (CMC group). Between 1980 and 1989, 72 patients and 37 patients underwent OMC (OMC group) and MVR (MVR group), respectively. Cumulative follow-up periods were 1982, 632 and 200 patient-years in the CMC, OMC and MVR groups, respectively. RESULTS. (1) Survival rate; In the CMC group there were 2 operative deaths due to severe mitral regurgitation (MR). There were 17 late deaths, due to reoperations in 4 patients, cerebral infarction in 4 patients, congestive heart failure in 3 patients, myocardial infarction in 2 patients and unknown causes in 4 patients. The survival rate was 95%, 91% and 86% at 5, 10 and 15 years, respectively, in the CMC group. In the OMC and MVR groups there was no death. (2) The event free rate was 89%, 79% and 58% at 5, 10 and 15 years, respectively, in the CMC group, 97% and 97% at 5 and 10 years in the OMC group, and 95% and 90% at 4 and 5 years in the MVR group. (3) Reoperations; In the CMC group of 40 patients (34%) required reoperations in an average of 10.4 years after the initial operation, due to re-MS in 22 patients, MR in 10 patients and MRS in the 8 patients. Reoperative findings consisted of clefts in the mitral leaflets in 7 patients. There were pulmonary hypertension in 15 patients and tricuspid regurgitation in 22 patients. Fourteen patients underwent tricuspid anuloplasty and one patient underwent a tricuspid valve replacement. In the OMC group one patient required a reoperation due to MR; in the MVR group one patient required a reoperation due to a thrombosed valve. CONCLUSION. In the CMC group the survival rate and the event free rate were lower, and the rate of reoperation was higher than in the other two groups.

  8. Acquired lumbar spinal stenosis.

    Deasy, JoAnn


    Lumbar spinal stenosis is the most frequent reason for spinal surgery in patients over age 65 years. In this condition, narrowing of the lumbar spinal canal and nerve root canals leads to painful, debilitating compression of spinal nerves and blood vessels. As the population ages, an increasing number of patients will be diagnosed and treated for lumbar spinal stenosis by primary care providers. This article reviews the pathophysiology, diagnosis, and management of lumbar spinal stenosis in adults over age 50 years.

  9. Treatment for rheumatic polymyalgia

    Azamat Makhmudovich Satybaldyev


    Full Text Available Glucocorticosteroids (GCs that provide a good and rapid clinical effect are the drug of choice to treat rheumatic polymyalgia (RP. A review of English language publications on the treatment of RP is given. Thirty (13 randomized and 17 observational studies of 20 and more patients with RP have been analyzed. Particular emphasis is laid on initial therapy with GCs, evaluation of their different daily doses, schemes for their dosage reduction and treatment termination, and on the frequency of recurrences. Studies dealing with the treatment with prednisone, prednisolone, methylprednisolone, and injectable sustained-release GC formulations are considered. The data of clinical trials of glucocorticoid-sparing agents (methotrexate, azathioprine during early and maintenance therapy are analyzed. The genetically engineered agents (infliximab, etanercept investigated in clinical trials are considered to be as alternatives; a case of using rituximab is described. The role of nonsteroidal anti-inflammatory drugs in the treatment of RP is also evaluated. An algorithm is proposed for the management of a patient with RP.

  10. Rheumatic fever in New Zealand.

    Webb, Rachel; Wilson, Nigel


    Acute rheumatic fever and its sequel rheumatic heart disease remain major unsolved problems in New Zealand, causing significant morbidity and premature death. The disease burden affects predominantly indigenous Māori and Pacific Island children and young adults. In the past decade these ethnic disparities are even widening. Secondary prophylaxis using 28-day intramuscular penicillin has been the mainstay of disease control. In the greater Auckland region, audit shows community nurse-led penicillin delivery rates of 95% and recurrence rates of less than 5%. The true penicillin failure rate of 0.07 per 100 patient years supports 4 weekly penicillin rather than more frequent dose regimens. Landmark primary prevention research has been undertaken supporting sore throat primary prevention programmes in regions with very high rheumatic fever rates. Echocardiographic screening found 2.4% previously undiagnosed rheumatic heart disease in socially disadvantaged children. Combined with secondary prevention, echocardiography screening has the potential to reduce the prevalence of severe rheumatic heart disease.

  11. Pathohistological Evidence of Smoldering Inflammation in Rheumatic Heart Disease with Massive Left Atrial Calcification.

    Shiba, Mikio; Sugano, Yasuo; Ikeda, Yoshihiko; Ishibashi-Ueda, Hatsue; Ohara, Takahiro; Hasegawa, Takuya; Kanzaki, Hideaki; Anzai, Toshihisa


    A 74-year-old man, who had a history of a mitral valve replacement for rheumatic heart disease (RHD) 30 years previously, was admitted with progressive heart failure. Massive calcification was observed around the left atrium on multidetector CT, in addition to a late gadolinium enhancement (LGE)-positive layer adjacently outside of the calcification on MRI. He underwent a second mitral valve replacement for the prosthetic valve failure. Pathohistological analyses of a tissue section of the left atrial wall from a surgical specimen revealed lymphocyte and macrophage infiltration that coincided with the LGE-positive layer on MRI, suggesting the existence of sustained active inflammation even after the long period of RHD.

    张国报; 乔刚; 赵小娟; 权晓强; 赵健; 程兆云


    Objective:To explore the triple-valve replacement experience in rheumatic heart valve disease. Methods: We reviewed our experience in A patients who underwent combined mitral and aortic valve replacement with tricuspid valve replacement between 2007 and 2011. Results:We found tricuspid annular dilatation and leaflet thickening resulting in tricuspid regurgitation in four patients, tricuspid commissural fusion leading to tricuspid stenosis in two patients. One patient received bioprosthetic valves replacement procedures in aortic and mitral position with tricuspid position. The other three patients received mechanical valves replacement procedures in aortic and mitral position, and bioprosthetic valve in tricuspid position. One patient died after operation due to low cardiac output syndrome. The mean follow-up was 30 months (range, 12 to 49 months). Post-operative heart function NYHA classifi-cation:two cases in class I, one case in class Ⅱ. Conclusion;We recommend the use of a bioprosthetic valve in tricuspid position if tricuspid valve should be replaced. Even if mechanical valves are implanted in the left side of the heart, a bioprosthetic valve may be a better choice at the tricuspid position.%目的:探讨风湿性心脏病手术中3个瓣膜同时置换的经验.方法:对4例同时置换二尖瓣、主动脉瓣和三尖瓣的病人资料进行分析.结果:术中发现4例病人均有三尖瓣环扩大和瓣叶增厚导致关闭不全,2例病人伴有交界融合导致瓣膜狭窄.1例病人接受了二尖瓣位、主动脉瓣位以及三尖瓣位生物瓣置换.另3例病人接受了二尖瓣位和主动脉瓣位机械瓣置换,以及三尖瓣位生物瓣置换.1例病人死于术后低心排.其他病人平均随访30个月(12~49个月),术后心功能I级2例,Ⅱ级1例.结论:如果三尖瓣需要置换时应使用生物瓣.尽管左侧心脏瓣膜应用机械瓣,三尖瓣位应用生物瓣仍是较好的选择.

  13. Fused aortic valve without an elliptical-shaped systolic orifice in patients with severe aortic stenosis: cardiac computed tomography is useful for differentiation between bicuspid aortic valve with raphe and tricuspid aortic valve with commissural fusion

    Bak, So Hyeon; Ko, Sung Min [Konkuk University School of Medicine, Departments of Radiology, Konkuk University Medical Center, Seoul (Korea, Republic of); Song, Meong Gun; Shin, Je Kyoun; Chee, Hyun Kun; Kim, Jun Suk [Konkuk University School of Medicine, Departments of Thoracic Surgery, Konkuk University Medical Center, Seoul (Korea, Republic of)


    The objective is to determine cardiac computed tomography (CCT) features capable of differentiating between bicuspid aortic valve (BAV) and tricuspid aortic valve (TAV) in severe aortic stenosis (AS) patients with fused cusp and without elliptical-shaped systolic orifices. We retrospectively enrolled 53 patients who had severe AS with fused cusps and without an elliptical-shaped systolic orifice on CCT and who had undergone surgery. CCT features were analyzed using: (1) aortic valve findings including cusp size, cusp area, opening shape, midline calcification, fusion length, calcium volume score, and calcium grade; (2) diameters of ascending and descending aorta, and main pulmonary artery; and (3) rheumatic mitral valve findings. The variables were evaluated using univariate and multivariate logistic regression analyses. At surgery, 19 patients had BAV and 34 had TAV. CCT features including uneven cusp size, uneven cusp area, round-shaped systolic orifice, longer cusp fusion, and dilatation of ascending aorta were significantly associated with BAV (P < 0.05). In particular, fusion length (OR, 1.76; P = 0.001), uneven cusp area (OR, 10.46; P = 0.012), and midline calcification (OR, 0.08; P = 0.013) were strongly associated with BAV. CCT provides diagnostic clues that helps differentiate between BAV with raphe and TAV with commissural fusion in patients with severe AS. (orig.)

  14. Robotic mitral valve surgery.

    Kypson, Alan P; Nifong, L Wiley; Chitwood, W Randolph


    A renaissance in cardiac surgery has begun. The early clinical experience with computer-enhanced telemanipulation systems outlines the limitations of this approach despite some procedural success. Technologic advancements, such as the use of nitinol U-clips (Coalescent Surgical Inc., Sunnyvale, CA) instead of sutures requiring manual knot tying, have been shown to decrease operative times significantly. It is expected that with further refinements and development of adjunct technologies, the technique of computer-enhanced endoscopic cardiac surgery will evolve and may prove to be beneficial for many patients. Robotic technology has provided benefits to cardiac surgery. With improved optics and instrumentation, incisions are smaller. The ergometric movements and simulated three-dimensional optics project hand-eye coordination for the surgeon. The placement of the wristlike articulations at the end of the instruments moves the pivoting action to the plane of the mitral annulus. This improves dexterity in tight spaces and allows for ambidextrous suture placement. Sutures can be placed more accurately because of tremor filtration and high-resolution video magnification. Furthermore, the robotic system may have potential as an educational tool. In the near future, surgical vision and training systems might be able to model most surgical procedures through immersive technology. Thus, a "flight simulator" concept emerges where surgeons may be able to practice and perform the operation without a patient. Already, effective curricula for training teams in robotic surgery exist. Nevertheless, certain constraints continue to limit the advancement to a totally endoscopic computer-enhanced mitral valve operation. The current size of the instruments, intrathoracic instrument collisions, and extrathoracic "elbow" conflicts still can limit dexterity. When smaller instruments are developed, these restraints may be resolved. Furthermore, a working port incision is still required for

  15. A timely reminder--rheumatic fever.

    Lilic, Nikola; Kumar, Priyanka


    Rheumatic fever is a disease diagnosed using the Jones criteria. The Jones criteria were designed using data from areas with a low prevalence of rheumatic fever. In New Zealand there is a high prevalence of rheumatic fever amongst Maori and Pacific peoples. A case is presented where a child of Samoan ethnicity is diagnosed and treated for rheumatic fever without fulfilling the Jones criteria. Evidence supporting the broadening of the diagnostic criteria in high prevalence areas is highlighted.

  16. The macrophages in rheumatic diseases

    Full Text Available Antonella Laria, Alfredomaria Lurati , Mariagrazia Marrazza , Daniela Mazzocchi, Katia Angela Re, Magda Scarpellini Rheumatology Unit, Fornaroli Hospital, Magenta, Italy Abstract: Macrophages belong to the innate immune system giving us protection against pathogens. However it is known that they are also involved in rheumatic diseases. Activated macrophages have two different phenotypes related to different stimuli: M1 (classically activated and M2 (alternatively activated. M1 macrophages release high levels of pro-inflammatory cytokines, reactive nitrogen and oxygen intermediates killing microorganisms and tumor cells; while M2 macrophages are involved in resolution of inflammation through phagocytosis of apoptotic neutrophils, reduced production of pro-inflammatory cytokines, and increased synthesis of mediators important in tissue remodeling, angiogenesis, and wound repair. The role of macrophages in the different rheumatic diseases is different according to their M1/M2 macrophages phenotype. Keywords: macrophage, rheumatic diseases

  17. Changes in Serum NT-Pro BNP and Left Atrial BNP Levels after Percutaneous Transvenous Mitral Commissurotomy in Sinus Rhythm Versus Atrial Firilation

    Leili Pourafkari


    Full Text Available Introduction: Natriuretic peptides are secreted from the heart in response to increased wall stress. Their levels are expected to be increased in patients with mitral stenosis (MS due tohigh left atrium (LA pressure and pulmonary artery pressure (PAP. Percutaneous transvenousmitral commissurotomy (PTMC if successful is pursued by a rapid decrease in LA pressure andsubsequent decrease in pulmonary artery pressure. The concurrent changes in natriuretic peptidelevels could be affected with heart rhythm.Methods: Forty five patients with severe rheumatic MS undergoing PTMC were enrolled. Weevaluated the serum NT-Pro BNP levels before and 24 hours after PTMC. BNP levels were alsomeasured from the blood samples obtained from LA before and 20 minutes after the procedure.Changes in biomarkers were assessed based on heart rhythm and success of the procedure.Results: While serum NT-Pro BNP levels showed significant decrease 24 hours after theprocedure (P= 0.04, BNP levels taken 20 minutes after PTMC from LA were similar to theirbaseline concentrations (P= 0.26. NT-Pro BNP levels decreased 51.7±182.86 pg/ml for SR and123.4±520 pg/ml for AF (P= 0.68.Conclusion: Immediate changes in BNP levels did not predict the success of procedure probablydue to the additional balloon inflation attempts in LA in several patients and half-life of BNP. BNPlevels obtained later may be of more value considering the half-life of this marker. Heart rhythmwas not found to influence the changes in biomarker levels. BNP and NT-pro BNP changes werenot found to predict success of the procedure.

  18. MitraClip Therapy for Mitral Regurgitation: Secondary Mitral Regurgitation.

    Feldman, Ted; Mehta, Arjun; Guerrero, Mayra; Levisay, Justin P; Salinger, Michael H


    Therapy for mitral regurgitation (MR) has been synonymous with mitral valve surgery. Operative approaches for degenerative MR repair have been associated with excellent results, with durable long term outcomes. Surgery for functional MR has been less successful. MitraClip has shown promise for functional MR, especiall in patinets who are high risk for surgery. The aggregate of nonrandomized global experience with MitraClip in functional MR has been consistent in showing improvements in symptoms and left ventricular remodeling. It remains to be seen how MitraClip therapy will compare with best medical therapy. The COAPT trial will clarify this question.

    Nakashima, Dainari; Ueda, Kohei; Tsukuda, Kyozo; Utsu, Noriaki; Kohki, Shimazu; Fushimi, Hiroaki; Miyakoshi, Kazuho


    A 62-year-old man was hospitalized for acute rheumatic fever. He had previously suffered from rheumatic fever at 15 years of age. The rheumatic fever was complicated by carditis, which caused valve disease that required surgical treatment. The incidence of rheumatic fever has decreased in most developed countries with improvements in sanitary conditions. The low incidence of this disease makes a timely and accurate diagnosis difficult. Due to the fact that both the first occurrence and recurrence of acute rheumatic fever can occur in the elderly and adults, this potential disease should not be overlooked when making a differential diagnosis.

  20. Medical therapy for rheumatic heart disease: is it time to be proactive rather than reactive?

    Rheumatic Heart Disease (RHD) is well known to be an active inflammatory process which develops progressive calcification and leaflet thickening over time. The potential for statin therapy in slowing the progression of valvular heart disease is still controversial. Retrospective studies have shown that medical therapy is beneficial for patients with calcific aortic stenosis and recently for rheumatic valve disease. However, the prospective randomized clinical trials have been negative to date. This article discusses the epidemiologic risk factors, basic science, retrospective and prospective studies in valvular heart disease and a future clinical trial to target RHD with statin therapy to slow the progression of this disease. Recent epidemiological studies have revealed the risk factors associated with valvular disease include male gender, smoking, hypertension and elevated serum cholesterol and are similar to the risk factors for vascular atherosclerosis. An increasing number of models of experimental hypercholesterolemia demonstrate features of atherosclerosis in the aortic valve (AV), which are similar to the early stages of vascular atherosclerotic lesions. Calcification, the end stage process of the disease, must be understood as a prognostic indicator in the modification of this cellular process before it is too late. This is important in calcific aortic stenosis as well as in rheumatic valve disease. There are a growing number of studies that describe similar pathophysiologic molecular markers in the development of rheumatic valve disease as in calcific aortic stenosis. In summary, these findings suggest that medical therapies may have a potential role in patients in the early stages of this disease process to slow the progression of RHD affecting the valves. This review will summarize the potential for statin therapy for this patient population.

  1. A Case of Mitral Valve Replacement with Neurologic Manifestations during Pregnancy

    Kambiz Alizadeh


    Full Text Available Introduction: Cardiopulmonary bypass in pregnant patient is considered a high-risk procedure.  Maternal mortality is similar to that of the non-pregnant females about 1.5-5%. Variations in the timing of surgical intervention, gestational age, maternal health sta­­­­tus, perfusion protocol, and pharmacologic therapy are all factors that can influence fetomaternal outcome. Case Report: We present a case of 26- year- old pregnant woman (G1, Ab0, D0 in gestational age of 36 weeks with sudden CVA and neurological sequelae (disartheria, paresthesia of right side of face. In her past medical history, she had no positive history of neurologic problems, diabetes mellitus, hyperlipidemia or cardiovascular diseases. Left perisylvian encephalitis was reported in her brain MRI. In trans-thoracic echocardiography moderate Mitral Regurgitation (MR, severe mitral stenosis with gradient of 9mmHg, and valve surface of 1cm2 was observed. In obstetrics consultation, a healthy male fetus with approximate gestational age of 37 weeks was reported. Finally the pregnancy ended by caesarean section under general anesthesia, with presence of cardiologist and a healthy newborn was delivered at age of 37 weeks. Four days after caesarean section, Mitral Valve Replacement (MVR was measured which proceeded successfully. Conclusion:Due to the risk of further neurological complications in a pregnant mother who suffers from mitral valve stenosis, provided the gestational age permits harmless termination of pregnancy, it is possible to perform the mitral valve replacement procedure during the same hospital stay after termination of pregnancy.

  4. Antiphospholipid syndrome and rheumatic fever: a case spanning three decades of changing concepts and common immunological mechanisms.

    Alcock, R; Elsik, M; Yiannikas, C; Yiannikas, J


    We present a case of primary antiphospholipid syndrome (APS), initially diagnosed as acute rheumatic fever, resulting in severe mitral valve incompetence. This case raises questions of the specificity of the Jones diagnostic criteria for rheumatic fever in a population where it is infrequently encountered. There are similarities in clinical, pathological and echocardiographic presentations between rheumatic fever and APS, in addition to common immunological mechanisms. Our case highlights the possibility that rather than rheumatic fever being primarily responsible for her recurrent attacks of chorea and arthritis, the streptococcal infections in our patient occurred either in the setting of underlying antiphospholipid antibodies ('second hit' phenomenon), or may have triggered the development of pathogenic antibodies (molecular mimicry), subsequently leading to the clinical evolution of APS. During the three decades of our patient and her recurrent problems, there has been an evolving knowledge of the mechanisms of APS and rheumatic fever, allowing us to extend our understanding beyond symptoms and syndromes, to a better realization of the underlying immunological relationship between the two.

    Liddicoat, John R; Mac Neill, Briain D; Gillinov, A Marc; Cohn, William E; Chin, Chi-Hui; Prado, Aldo D; Pandian, Natesa G; Oesterle, Stephen N


    Annuloplasty is the cornerstone of surgical mitral valve repair. A percutaneous transvenous catheter-based approach for mitral valve repair was tested by placing a novel annuloplasty device in the coronary sinus of sheep with acute ischemic mitral regurgitation. Mitral regurgitation was reduced from 3-4+ to 0-1+ in all animals (P < 0.03). The annuloplasty functioned by reducing septal-lateral mitral annular diameter (30 +/- 2.1 mm preinsertion vs. 24 +/- 1.7 mm postinsertion; P < 0.03). These preliminary experiments demonstrate that percutaneous mitral annuloplasty is feasible. Further study is necessary to demonstrate long-term safety and efficacy of this novel approach.

  8. Rheumatic fever and rheumatic heart disease in Bangladesh: A review.

    Islam, A K M Monwarul; Majumder, A A S


    Rheumatic fever (RF) and rheumatic heart disease (RHD) are the most-common cardiovascular disease in young people aged <25 years, globally. They are important contributors to cardiovascular morbidity and mortality in Bangladesh. Classical risk factors, i.e. poverty, overcrowding, ignorance, and insufficient health care services were responsible for the high incidence and prevalence of these diseases over the last century. In concert with the progresses in socioeconomic indicators, advances in health sectors, improved public awareness, and antibiotic prophylaxis, acute RF came into control. However, chronic RHD continues to be prevalent, and the actual disease burden may be much higher. RHD predominantly affects the young adults, seriously incapacitates them, follows a protracted course, gets complicated because of delayed diagnosis and is sometimes maltreated. The treatment is often palliative and expensive. Large-scale epidemiological and clinical researches are needed to formulate evidence-based national policy to tackle this important public health issue in future.

  9. Acute rheumatic fever and rheumatic heart disease among children--American Samoa, 2011-2012.

    Beaudoin, Amanda; Edison, Laura; Introcaso, Camille E; Goh, Lucy; Marrone, James; Mejia, Amelita; Van Beneden, Chris


    Acute rheumatic fever is a nonsuppurative, immune-mediated consequence of group A streptococcal pharyngitis (strep throat). Recurrent or severe acute rheumatic fever can cause permanent cardiac valve damage and rheumatic heart disease, which increases the risk for cardiac conditions (e.g., infective endocarditis, stroke, and congestive heart failure). Antibiotics can prevent acute rheumatic fever if administered no more than 9 days after symptom onset. Long-term benzathine penicillin G (BPG) injections are effective in preventing recurrent acute rheumatic fever attacks and are recommended to be administered every 3-4 weeks for 10 years or until age 21 years to children who receive a diagnosis of acute rheumatic fever. During August 2013, in response to anecdotal reports of increasing rates of acute rheumatic fever and rheumatic heart disease, CDC collaborated with the American Samoa Department of Health and the Lyndon B. Johnson Tropical Medical Center (the only hospital in American Samoa) to quantify the number of cases of pediatric acute rheumatic fever and rheumatic heart disease in American Samoa and to assess the potential roles of missed pharyngitis diagnosis, lack of timely prophylaxis prescription, and compliance with prescribed BPG prophylaxis. Using data from medical records, acute rheumatic fever incidence was calculated as 1.1 and 1.5 cases per 1,000 children aged ≤18 years in 2011 and 2012, respectively; 49% of those with acute rheumatic fever subsequently received a diagnosis of rheumatic heart disease. Noncompliance with recommended prophylaxis with BPG after physician-diagnosed acute rheumatic fever was noted for 22 (34%) of 65 patients. Rheumatic heart disease point prevalence was 3.2 cases per 1,000 children in August 2013. Establishment of a coordinated acute rheumatic fever and rheumatic heart disease control program in American Samoa, likely would improve diagnosis, treatment, and patient compliance with BPG prophylaxis.

  10. Mitral valve restoration using the No-React(R MitroFix™: a novel concept

    Oertel Frank


    Full Text Available Abstract Background Mitral Valve Repair (MVRP has been shown to be significantly superior to Mitral Valve Replacement (MVR. Since the majority of repairs involve the Posterior Mitral Leaflet (PML and not the Anterior Mitral Leaflet (AML, the monocuspidalisation of the Mitral Valve (MV can be achieved with a bio-posterior leaflet that imitates a closed PML. This approach may have the benefit of restoring the competence of the MV without reducing its effective orifice area. Methods We have used a new concept and device, the MitroFixTM, to correct MV regurgitation due to pathology of the PML. The device comes with functional sizers both of which have identical shape and size. This allows the surgeon to pre-test the success of the restoration. From December 2006 to October 2011, 51 MitroFixTM devices were implanted at three institutions. Results The mean age of the patients (32 males and 19 females was 67.7 years. 37 of them were in NYHA class III or IV and all patients suffered from severe mitral valve regurgitation (MR. 31 patients underwent combined surgery. Successful implantation of the MitroFix™ device was performed in 51/53 patients.Mean cross-clamp time was 63.6 min (range: 29-118 min. Six patients had additional reconstructive procedures of the AML (chordae transfer, neo-chordae, triangular resection. At discharge, 33 patients showed no MR in the TTE and 17 patients exhibited trivial (I or moderate (II MR. The mean gradient was 4.0 mmHg and mean EOA was 2.52cm^2 (range: 1.5-4.0cm2. All patients were classified as being in NYHA class I or II. Conclusion The MitroFixTM Mitral Valve Restoration Device is a new concept that offers an effective treatment of MR. The restoration of the mitral valve with the MitroFix™ device offers the advantage of preserving the AML and providing good coaptation with a prosthetic PML. Importantly, this preliminary evaluation indicates a mean effective orifice area ( EOA of 2.5cm2 in MV receiving a Mitro

  11. Ligation or distortion of the right circumflex artery during minimal invasive mitral valve repair detected by transesophageal echocardiography.

    Ender, Joerg; Gummert, Jan; Fassl, Jens; Krohmer, Eugen; Bossert, Thorsten; Mohr, Friedrich W


    A 43-year-old male patient undergoing mitral valve repair because of severe mitral regurgitation as a result of P2 prolapse was treated with insertion of neochords and a 36 Carpentier-Edwards physio-ring. After weaning from cardiopulmonary bypass, S-T elevation in leads II, III, and aVF occurred. On transesophageal echocardiography an occlusion or distortion of the circumflex artery by ring sutures was suggested, because coronary flow was no longer detected by color Doppler. Despite stable hemodynamics an angiogram was performed, which confirmed the diagnosis of stenosis of the circumflex artery. During reoperation 4 sutures placed at the P1 segment of the mitral valve annuloplasty were corrected. Transesophageal echocardiography could detect a good flow of the circumflex artery and the electrocardiographic changes disappeared.

  12. Blood serum apolipoproteins B and A-I in females suffering from rheumatic heart valve disease.

    Stakisaitis, Donatas; Maksvytis, Arūnas; Salcius, Kestutis; Benetis, Rimantas


    With the aim to check whether the atherogenic factors are involved in the mechanisms of valve fibrosis, we have studied the blood serum concentrations of apolipoproteins (apo) A-I and B concentration in patients suffering from rheumatic heart valve fibrosis. The quantities of apoA-I and apoB in the blood serum were tested by the ELISA method. Concentration of apoA-I and B in the blood serum was determined in rheumatic females with replacement of the damaged valves: after aortic valve operation (n=11; mean age 43.3+/-3.6 years) and after mitral valve operation (n=29; 41.3+/-4.1). The results obtained for rheumatic patients were compared with the data on age-matched healthy females (n=43; 39.5+/-5.2 years). Significantly lower apoA-I level in the blood serum of all patients suffering from rheumatic heart valve disease was determined as compared with controls: in the pooled group of patients (1.02+/-0.22 vs 1.23+/-0.23 g/l, Pvalve replacement (0.98+/-0.21 vs. 1.23+/-0.23 g/l, Pvalve surgery (1.03+/-0.23 g/l vs 1.23+/-0.23 g/l, Pheart valve disease did not differ from that of controls. The apoB/apoA-I ratio for patients with valve fibrotic damage was significantly higher as compared to controls in all groups (Pvalve fibrosis was caused by lower apoA-I levels in blood serum. The obtained results indicate that decreased apoA-I levels in blood serum can be indicative of valve fibrosis in rheumatic heart valve disease patients.

  13. Early Clinical Outcome of Mitral Valve Replacement Using a Newly Designed Stentless Mitral Valve for Failure of Initial Mitral Valve Repair.

    Nishida, Hidefumi; Kasegawa, Hitoshi; Kin, Hajime; Takanashi, Shuichiro


    Here we report the early outcome of mitral valve replacement using a newly designed stentless mitral valve for failure of initial mitral valve repair. Mitral valve plasty (MVP) for mitral regurgitation is currently a standard technique performed worldwide. However, whether mitral valve repair should be performed for patients with advanced leaflet damage or complicated pathology remains controversial. Mitral valve replacement might be feasible for patients who have undergone failed initial MVP; however, it is not an optimal treatment because of poor valve durability and the need for anticoagulative therapy. We report two cases of successful mitral valve replacement using a newly designed stentless mitral valve made of fresh autologous pericardium, which may have a potential benefit over mitral valve repair or mitral valve replacement with a mechanical or bioprosthetic valve.

  17. Mitral valve plasty for mitral regurgitation after blunt chest trauma.

    Kumagai, H; Hamanaka, Y; Hirai, S; Mitsui, N; Kobayashi, T


    A 21 year-old woman was admitted to our hospital because of chest and back pain after blunt chest trauma. On admission, consciousness was clear and a physical examination showed labored breathing. Her vital signs were stable, but her breathing gradually worsened, and artificial respiration was started. The chest roentgenogram and a subsequent chest computed tomographic scans revealed contusions, hemothorax of the left lung and multiple rib fractures. A transthoracic echocardiography (TTE) revealed normal left ventricular wall motion and mild mitral regurgitation (MR). TTE was carried out repeatedly, and revealed gradually progressive MR and prolapse of the posterior medial leaflet, although there was no congestive heart failure. After her general condition had recovered, surgery was performed. Intraoperative transesophageal echocardiography (TEE) revealed torn chordae at the posterior medial leaflet. The leaflet where the chorda was torn was cut and plicated, and posterior mitral annuloplasty was performed using a prosthetic ring. One month later following discharge, the MR had disappeared on TTE.

  18. Advanced heart block in acute rheumatic fever.

    Hubail, Zakariya; Ebrahim, Ishaq M


    First degree heart block is considered a minor criterion for the diagnosis of this condition. The cases presented here demonstrate that higher degrees of heart block do occur in rheumatic fever. Children presenting with acquired heart block should be worked-up for rheumatic fever. Likewise, it is imperative to serially follow the electrocardiogram in patients already diagnosed with acute rheumatic fever, as the conduction abnormalities can change during the course of the disease.

    P Yadav, P Joshi, J Gupta, D Joseph, P Sakhi


    Full Text Available Rheumatic fever and rheumatic heart disease continue to affect millions of people around the world. Children and adolescents of the developing countries are especially susceptible to this disease. To asses the prevalence of Rheumatic Fever /Rheumatic heart disease in an urban area, we do survey of children aged between 5 to 16 years studying in various government schools in Indore district which were selected randomly. Out of 9879 students enrolled in the study 9526 were examined, the percentage of absentees being ten. Revised Jones criterion (1992 was used for the diagnosis of rheumatic fever. Doppler echocardiography is used to confirm the diagnosis of rheumatic heart disease. A total of seven cases of definite rheumatic heart disease (out of 13 suspected cases were identified giving overall prevalence rate of 0.73 per 1000. Fifty percent rheumatic heart disease cases gave a history suggestive of rheumatic fever. No case of active rheumatic fever could be identified. The study gave lower result than that reported in earlier studies from developing countries but it is similar to that reported from Indore district in 2009. It is concluded that there is some downward trend in rheumatic fever / rheumatic heart disease prevalence but the low prevalence is also due to the use of Doppler echocardiography which has prevented over diagnosis in the present study.

    Rahul Basu


    Full Text Available A 50-year-old male presented with erysipelothrix rhusiopathiae (ER endocarditis of the mitral valve, severe mitral regurgitation, and heart failure. The ER endocarditis destroyed the native mitral annulus therefore a new annulus was created for the suspension of the mitral bioprosthesis. Postoperative neoannulus dehiscence and leak prompted to redo surgery where transesophageal echocardiography (TEE played an important role in pointing out the exact location of perineoannular leaks for repair.

  2. Congenital tracheobronchial stenosis.

    Hewitt, Richard J; Butler, Colin R; Maughan, Elizabeth F; Elliott, Martin J


    Congenital tracheobronchial stenosis is a rare disease characterized by complete tracheal rings that can affect variable lengths of the tracheobronchial tree. It causes high levels of morbidity and mortality both due to the stenosis itself and to the high incidence of other associated congenital malformations. Successful management of this complex condition requires a highly individualized approach delivered by an experienced multidisciplinary team, which is best delivered within centralized units with the necessary diverse expertise. In such settings, surgical correction by slide tracheoplasty has become increasingly successful over the past 2 decades such that long-term survival now exceeds 88%, with normalization of quality of life scores for patients with non-syndrome-associated congenital tracheal stenosis. Careful assessment and planning of treatment strategies is of paramount importance for both successful management and the provision of patients and carers with accurate and realistic treatment counseling.

    Rheumatic fever and acute rheumatic carditis (ARC), though now rare in developed countries, are the main cause of acquired heart disease in children and young adults and remain endemic in developing countries. This study aims to establish the current prevalence of ARC in Ivory Coast. A cross-sectional retrospective study was performed between January 2000 and December 2009 in the pediatric wards of the three university hospitals in Abidjan and in the Institute of Cardiology of Abidjan. It included all patients whose final diagnosis was ARC. There were 126 patients of which 57.1% were female. The mean age was 15 ± 6.7 years (range: 4 to 28 years). The average annual prevalence was 12.6 cases, with two peaks observed during the years 2004 (27 cases) and 2005 (20 cases). The hospital prevalence of ARC in the 10-year period was 1.1‰ which is less than in previous decades. The principal presentation leading to discovery of the ARC was heart failure (68.9%). This symptom was due to significant valvular regurgitation with dilatation of the cardiac chambers observed in 65.9%. Mitral regurgitation was the main lesion observed (87.3%). Apart from the cases of isolated pericarditis and three cases of mild mitral regurgitation, all other patients were suffering from valvular lesions as a result of previous rheumatic fever.

  7. Lumbar stenosis: clinical case

    Pedro Sá


    Full Text Available Lumbar stenosis is an increasingly common pathological condition that is becoming more frequent with increasing mean life expectancy, with high costs for society. It has many causes, among which degenerative, neoplastic and traumatic causes stand out. Most of the patients respond well to conservative therapy. Surgical treatment is reserved for patients who present symptoms after implementation of conservative measures. Here, a case of severe stenosis of the lumbar spine at several levels, in a female patient with pathological and surgical antecedents in the lumbar spine, is presented. The patient underwent two different decompression techniques within the same operation.

  8. Severe iatrogenic nostril stenosis

    Ali Ebrahimi


    Full Text Available Nostril stenosis (narrowing of the nasal inlet is an uncommon deformity which results in aesthetic and breathing discomfort in patients. The literature review shows that trauma, infection, iatrogenic insults and congenital lesions are major causes of stenosis. Nowadays, rhinoplasty is one of most popular aesthetic surgeries which may have complications such as bleeding, swelling, bruising, asymmetry, obstruction of nasal airways. We present a 30-year-old female patient, who complained about breathing and aesthetic difficulties due to external nasal valve obstruction and nasal deformity. Past medical history showed that the patient had undergone three unsuccessful rhinoplasty surgeries with aesthetic goals.

Statistical analysis of data obtained was done using SPSS 16. Results: The total number of attendees of all the medical outpatient clinics during the 9-year period was 67,378, with a subset of 9423 attending the cardiology clinic. There were 11 cases of RHD, which translates to a prevalence of 0.16/1000 and 1.2/1000 for medical outpatient clinics and the cardiology clinic respectively. The mean age of the patients was 25.64 ± 9.65 years, age range 14–40 years and male to female ratio of 1:1.2. The most common valve affected was mitral (90.9%, followed by the aortic (36.4%, and the tricuspid (18.2%. Mitral and aortic lesions coexisted in 18.2% of the patients, and late presentation was common in all RHD cases. Heart failure was the most common complication (90.9%. Other complications were secondary pulmonary hypertension (36.4%, infective endocarditis (27.3%, atrial fibrillation (27.3%, cardioembolic cerebrovascular disease (18.2%, and atrial flutter (9.1%. Mortality was 9.1%, while only one patient (9.1% had definitive surgery. Financial constraints precluded others from having definitive surgery.Conclusion: The prevalence of RHD has declined considerably as a result of improvements in the primary health care delivery system, with widespread use

  10. Mapping of mitral regurgitant defects by cardiovascular magnetic resonance in moderate or severe mitral regurgitation secondary to mitral valve prolapse

    Raffel Owen C


    Full Text Available Abstract Purpose In mitral valve prolapse, determining whether the valve is suitable for surgical repair depends on the location and mechanism of regurgitation. We assessed whether cardiovascular magnetic resonance (CMR could accurately identify prolapsing or flail mitral valve leaflets and regurgitant jet direction in patients with known moderate or severe mitral regurgitation. Methods CMR of the mitral valve was compared with trans-thoracic echocardiography (TTE in 27 patients with chronic moderate to severe mitral regurgitation due to mitral valve prolapse. Contiguous long-axis high temporal resolution CMR cines perpendicular to the valve commissures were obtained across the mitral valve from the medial to lateral annulus. This technique allowed systematic valve inspection and mapping of leaflet prolapse using a 6 segment model. CMR mapping was compared with trans-oesophageal echocardiography (TOE or surgical inspection in 10 patients. Results CMR and TTE agreed on the presence/absence of leaflet abnormality in 53 of 54 (98% leaflets. Prolapse or flail was seen in 36 of 54 mitral valve leaflets examined on TTE. CMR and TTE agreed on the discrimination of prolapse from flail in 33 of 36 (92% leaflets and on the predominant regurgitant jet direction in 26 of the 27 (96% patients. In the 10 patients with TOE or surgical operative findings available, CMR correctly classified presence/absence of segmental abnormality in 49 of 60 (82% leaflet segments. Conclusion Systematic mitral valve assessment using a simple protocol is feasible and could easily be incorporated into CMR studies in patients with mitral regurgitation due to mitral valve prolapse.

  11. Impact of aspirin use in the incidence of thromboembolic events after bioprosthesis replacement in patients with rheumatic disease

    André Rodrigues Durães


    Full Text Available INTRODUCTION: There is still much debate regarding the kind of antithrombotic therapy in the immediate postoperative period of bioprosthesis replacement (first three months. Thus, the authors consider relevant to determine the contemporary incidence of thromboembolic events in rheumatic patients early after implantation of aortic and mitral bioprosthesis replacement (first 90 days in the post-operative period and perform a comparison between isolated Aspirin uses versus no-antiplatelet therapy, in this same context. METHODS: Between the period of January 2010 to July 2012, all consecutive rheumatic patients, with basal sinus rhythm, who performed mitral and aortic valve replacement with bioprosthesis (pericardial bovine, were included in this prospective cohort study, 184 patients in total. The primary endpoint evaluated were the rate of embolic events. RESULTS: In the first 30 days, there were three cerebral ischemic events among patients treated in Aspirin group (5.2% compared with two events in patients without Aspirin therapy (1.7%, HR = 3.18; 95% CI 0.5 to 19.6; P=0.33. Between 31 and 90 days postoperatively, no patient had a primary outcome. The embolism-free survival, bleeding events and the overall survival were not statistically significant between the aspirin and no-antiplatelet groups. CONCLUSION: In conclusion, in this prospective cohort of rheumatic patients, we found a low and very rare incidence rate of embolic events during the first 90 days postoperative period in mitral and isolated aortic position, respectively. The use of aspirin did not significantly reduce the rate of thromboembolism.

  12. Valve Replacement with a Sutureless Aortic Prosthesis in a Patient with Concomitant Mitral Valve Disease and Severe Aortic Root Calcification.

    Lio, Antonio; Scafuri, Antonio; Nicolò, Francesca; Chiariello, Luigi


    Aortic valve replacement with concomitant mitral valve surgery in the presence of severe aortic root calcification is technically difficult, with long cardiopulmonary bypass and aortic cross-clamp times. We performed sutureless aortic valve replacement and mitral valve annuloplasty in a 68-year-old man who had severe aortic stenosis and moderate-to-severe mitral regurgitation. Intraoperatively, we found severe calcification of the aortic root. We approached the aortic valve through a transverse aortotomy, performed in a higher position than usual, and we replaced the valve with a Sorin Perceval S sutureless prosthesis. In addition, we performed mitral annuloplasty with use of an open rigid ring. The aortic cross-clamp time was 63 minutes, and the cardiopulmonary bypass time was 83 minutes. No paravalvular leakage of the aortic prosthesis was detected 30 days postoperatively. Our case shows that the Perceval S sutureless bioprosthesis can be safely implanted in patients with aortic root calcification, even when mitral valve disease needs surgical correction.

  13. [Experience of Mitral Valve Replacement Using a Pulmonary Autograft (Ross II Operation) in an Infant;Report of a Case].

    Kawahito, Tomohisa; Egawa, Yoshiyasu; Yoshida, Homare; Shimoe, Yasushi; Onishi, Tatsuya; Miyagi, Yuhichi; Terada, Kazuya; Ohta, Akira


    A 24-day-old boy suddenly developed progressive heart failure and was transported to our hospital. Echocardiography showed massive mitral regurgitation due to chordal rupture. Mitral valve repair was performed at 28 days of life, but postoperative valvular function was not satisfactory. A mechanical valve was implanted in the supra-annular position at 37 days of life. Two months after valve replacement, the mechanical valve was suddenly stuck. Emergent redo valve replacement was performed, but the prosthetic valve became stuck again 2 months after the 3rd operation, despite sufficient anti-coagulation therapy. At the 4th operation (6 months after birth), we implanted a pulmonary autograft in the mitral position instead of another mechanical valve in an emergent operation. The right ventricular outflow tract was reconstructed with a valved conduit. A postoperative catheter examination, which was performed 1 year after the Ross II operation, showed mild mitral stenosis with no regurgitation. Previous reports of Ross II operations in infants are rare and long-term results are unknown. However, we advocate that this procedure should be a rescue operation for mitral valve dysfunction in the early period of infants.

  14. Left Ventricular Diastolic Function and Characteristics in Fetal Aortic Stenosis

    Friedman, Kevin G.; Schidlow, David; Freud, Lindsay; Escobar-Diaz, Maria; Tworetzky, Wayne


    Fetal aortic valvuloplasty (FAV) has shown promise in averting progression of mid-gestation aortic stenosis (AS) to hypoplastic left heart syndrome in a subset of patients. Patients who achieve biventricular circulation after FAV frequently have left ventricular (LV) diastolic dysfunction (DD). This study evaluates DD in fetuses with AS by comparing echocardiographic indices of LV diastolic function in fetuses undergoing FAV (n=20) to controls (n=40) and evaluates for LV factors associated with DD in FAV patients. We also compared pre- and post-FAV DD variables (n=16). Median gestational age (24 weeks, range 18–29 weeks) and fetal heart rate were similar between FAV and controls. Compared to controls, FAV patients had universally abnormal LV diastolic parameters including fused mitral inflow E and A waves (p=0.008), higher E velocity(p<0.001), shorter mitral inflow time (p=0.001), lower LV lateral annulus E′ (p<0.001), septal E′ (p=0.003) and higher E/E′ (p<0.001) than controls. FAV patients had abnormal right ventricular mechanics with higher tricuspid inflow E velocity (p<0.001), and shorter tricuspid inflow time (p=0.03). Worse LV diastolic function (lower LV E′) was associated with higher endocardial fibroelastosis (EFE) grade (r=0.74, p<0.001), large LV volume (r=0.55, p=0.013) and sphericity (r=0.58, P=0.009) and with lower LV pressure by mitral regurgitation jet (r=−0.68, p<0.001). Post-FAV, fewer patients had fused mitral inflow E and A than pre-FAV (p=0.05) and septal E′ was higher (=0.04). In conclusion, fetuses with mid-gestation AS have evidence of marked DD. Worse DD is associated with larger, more spherical LV, with more extensive EFE and lower LV pressure. PMID:24819899

    Wang, Y N; Li, T; Gu, J R; Yu, B Y


    To investigate the expression and the effect of connective tissue growth factor (CTGF) on rheumatic myocardial fibrosis of rheumatic heart disease (RHD). The papillary muscles samples were obtained from patients with RHD during mitral valve replacement.The expression of TGF-β1, CTGF mRNA and CTGF protein were detected with semiquantitative RT-PCR technique and immunohistochemistry technologyin the papillary muscles cell from 41RHD patients and 20 normal papillary muscles samples.The area of myocardial fibrosis was measured by imaging analysis system. SPSS package was used to analyze the relationship between the expression of CTGF and the area of myocardial fibrosis. Compared with normal controls (PU 2.4±0.9), the mean level of CTGF protein expression in the papillary muscles samples of the RHD patients (PU 44.7±6.0) was significantly increased(Pfibrosis (r=0.856, Pfibrosis of RHD.

  18. Tai chi and rheumatic diseases.

    Wang, Chenchen


    Tai chi is a complex multicomponent mind-body exercise. Many studies have provided evidence that tai chi benefits patients with a variety of chronic disorders. This form of mind-body exercise enhances cardiovascular fitness, muscular strength, balance, and physical function and seems to be associated with reduced stress, anxiety, and depression and improved quality of life. Thus, despite certain limitations in the evidence, tai chi can be recommended to patients with osteoarthritis, rheumatoid arthritis, and fibromyalgia as a complementary and alternative medical approach. This article overviews the current knowledge about tai chi to better inform clinical decision making for rheumatic patients. Copyright © 2011 Elsevier Inc. All rights reserved.

    Mitral valve disease is a frequent cause of heart failure and death. Emerging evidence indicates that the mitral valve is not a passive structure, but—even in adult life—remains dynamic and accessible for treatment. This concept motivates efforts to reduce the clinical progression of mitral valve disease through early detection and modification of underlying mechanisms. Discoveries of genetic mutations causing mitral valve elongation and prolapse have revealed that growth factor signalling and cell migration pathways are regulated by structural molecules in ways that can be modified to limit progression from developmental defects to valve degeneration with clinical complications. Mitral valve enlargement can determine left ventricular outflow tract obstruction in hypertrophic cardiomyopathy, and might be stimulated by potentially modifiable biological valvular–ventricular interactions. Mitral valve plasticity also allows adaptive growth in response to ventricular remodelling. However, adverse cellular and mechanobiological processes create relative leaflet deficiency in the ischaemic setting, leading to mitral regurgitation with increased heart failure and mortality. Our approach, which bridges clinicians and basic scientists, enables the correlation of observed disease with cellular and molecular mechanisms, leading to the discovery of new opportunities for improving the natural history of mitral valve disease.

  3. Mitral Valve Repair: The Chordae Tendineae

    Carlos-A Mestres


    Full Text Available Repair of the mitral valve is the treatment of choice for mitral valve regurgitation when the anatomy is favorable. It is well known that mitral valve repair enjoys better clinical and functional results than any other type of valve substitute. This fact is beyond doubt regardless of the etiology of the valve lesion and is of particular importance in degenerative diseases.This review analyzes the most important advances in the knowledge of the anatomy, pathophysiology, and chordal function of the mitral valve as well as the different alternatives in the surgical repair and clinical results of the most prevalent diseases of the mitral valve. An attempt has been made to organize the acquired information available in a practical way.

  4. Misconceptions and Facts About Mitral Regurgitation.

    Argulian, Edgar; Borer, Jeffrey S; Messerli, Franz H


    Mitral regurgitation is a common heart valve disease. It is defined to be primary when it results from the pathology of the mitral valve apparatus itself and secondary when it is caused by distortion of the architecture or function of the left ventricle. Although the diagnosis and management of mitral regurgitation rely heavily on echocardiography, one should bear in mind the caveats and shortcomings of such an approach. Clinical decision making commonly focuses on the indications for surgery, but it is complex and mandates precise assessment of the mitral pathology, symptom status of the patient, and ventricular performance (right and left) among other descriptors. It is important for healthcare providers at all levels to be familiar with the clinical picture, diagnosis, disease course, and management of mitral regurgitation.

    Sondergaard, Lars; Brooks, Matthew; Ihlemann, Nikolaj;


    OBJECTIVES: As many as 50% of patients with severe symptomatic mitral valve regurgitation are denied surgical valve replacement or repair due to high operative risk. We describe an early series of cases of transcatheter implantation with a CardiAQ™ mitral valve via a transapical approach. METHODS......: Three consecutive patients with an Society of Thoracic Surgeons (STS) mortality score of >22% were selected for transcatheter mitral valve implantation (TMVI) on compassionate grounds. All patients were elderly, had severe mitral regurgitation (MR), were in Class IV heart failure and deemed unsuitable...... bypass surgery (n = 2), severe pulmonary hypertension (n = 1) and moderate to severe chronic renal failure (n = 3). A CardiAQ mitral valve was implanted using fluoroscopy and transoesophageal (TEE) guidance via a standard transapical approach. RESULTS: Accurate prosthesis positioning and deployment...

  6. Aortic valve replacement in children under 16 years of age with congenital or rheumatic valvular disease. A study of 64 cases.

    Abid, F; Abid, A; Fekih, M; Zaouali, R M; Ben Ismail, M


    Sixty-four children have had a single aortic valve replacement under 16 years of age, 50 for rheumatic disease (47) or bacterial endocarditis (3) (group I) and 14 for a congenital aortic valve lesion (group II), 38 were disk prostheses and 26 were ball prostheses. Associated procedures had to be performed 31 times, with widening of a small aortic annulus by a patch in 7 patients. The early mortality was 12.5%. Of 56 survivors, 55 were followed postoperatively for a mean period of 7 years (group I: 44, group II: 11). Forty of the 55 patients were anticoagulated (correctly maintained in only 24 patients), 15 were not anticoagulated. A high rate of late complications was observed. Thrombo-embolic accidents in 5 patients with inefficient anticoagulant treatment, 2 haemorrhagic episodes, 7 prosthetic leaks; specific problems related to this group of young patients were: recurrence of rheumatic fever with increasing severity of mitral valve disease requiring mitral valve replacement in 5 patients and outgrowth of the prosthesis, which affected 7 patients; this complication is the result of either fibrous deposit around the valve annulus or such a small annulus that the surgeon could only implant a small prosthesis. Ten patients required 11 reoperations for various reasons. The main reason for reoperation was mitral valve replacement for worsening of mitral valve disease caused by recurrence of rheumatic fever. A high late mortality 10/55 (18%) was noted. The main cause of death was a perivalvular leak (5); 1 late death was caused by a stenotic number 17 Björk-Shiley valve.(ABSTRACT TRUNCATED AT 250 WORDS)

  8. Transcatheter mitral valve repair in osteogenesis imperfecta associated mitral valve regurgitation.

    van der Kley, Frank; Delgado, Victoria; Ajmone Marsan, Nina; Schalij, Martin J


    Osteogenesis imperfecta is associated with increased prevalence of significant mitral valve regurgitation. Surgical mitral valve repair and replacement are feasible but are associated with increased risk of bleeding and dehiscence of implanted valves may occur more frequently. The present case report describes the outcomes of transcatheter mitral valve repair in a patient with osteogenesis imperfecta. A 60 year-old patient with osteogenesis imperfecta and associated symptomatic moderate to severe mitral regurgitation underwent transthoracic echocardiography which showed a nondilated left ventricle with preserved systolic function and moderate to severe mitral regurgitation. On transoesophageal echocardiography the regurgitant jet originated between the anterolateral scallops of the anterior and posterior leaflets (A1-P1). Considering the comorbidities associated with osteogenesis imperfecta the patient was accepted for transcatheter mitral valve repair using the Mitraclip device (Abbott vascular, Menlo, CA). Under fluoroscopy and 3D transoesophageal echocardiography guidance, a Mitraclip device was implanted between the anterolateral and central scallops with significant reduction of mitral regurgitation. The postoperative evolution was uneventful. At one month follow-up, transthoracic echocardiography showed a stable position of the Mitraclip device with no mitral regurgitation. Transcatheter mitral valve repair is feasible and safe in patients with osteogenesis imperfecta and associated symptomatic significant mitral regurgitation.

  9. Congenital pyriform aperture stenosis

    Osovsky, Micky [Schneider Pediatric Hospital, Department of Neonatology, Petach Tikvah (Israel); Rabin Medical Center, Department of Neonatology, Schneider Children' s Medical Center of Israel, Beilinson Campus, Petah Tikvah (Israel); Aizer-Danon, Anat; Horev, Gadi [Schneider Pediatric Hospital, Department of Pediatric Radiology, Petach Tikvah (Israel); Sirota, Lea [Schneider Pediatric Hospital, Department of Neonatology, Petach Tikvah (Israel)


    Nasal airway obstruction is a potentially life-threatening condition in the newborn. Neonates are obligatory nasal breathers. The pyriform aperture is the narrowest, most anterior bony portion of the nasal airway, and a decrease in its cross-sectional area will significantly increase nasal airway resistance. Congenital nasal pyriform aperture stenosis (CNPAS) is a rare, unusual form of nasal obstruction. It should be considered in the differential diagnosis of any neonate or infant with signs and symptoms of upper airway compromise. It is important to differentiate this level of obstruction from the more common posterior choanal stenosis or atresia. CNPAS presents with symptoms of nasal airway obstruction, which are often characterized by episodic apnea and cyclical cyanosis. (orig.)

  10. Diagnostic criteria of acute rheumatic fever.

    Burke, Rebecca J; Chang, Christopher


    Acute rheumatic fever is an inflammatory sequela of Group A Streptococcal pharyngitis that affects multiple organ systems. The incidence of acute rheumatic fever has been declining even before the use of antibiotics became widespread, however the disease remains a significant cause of morbidity and mortality in children, particularly in developing countries and has been estimated to affect 19 per 100,000 children worldwide. Acute rheumatic fever is a clinical diagnosis, and therefore subject to the judgment of the clinician. Because of the variable presentation, the Jones criteria were first developed in 1944 to aid clinicians in the diagnosis of acute rheumatic fever. The Jones criteria have been modified throughout the years, most recently in 1992 to aid clinicians in the diagnosis of initial attacks of acute rheumatic fever and to minimize overdiagnosis of the disease. Diagnosis of acute rheumatic fever is based on the presence of documented preceding Group A Streptococcal infection, in addition to the presence of two major manifestations or one major and two minor manifestations of the Jones criteria. Without documentation of antecedent Group A Streptococcal infection, the diagnosis is much less likely except in a few rare scenarios. Carditis, polyarthritis and Sydenham's chorea are the most common major manifestations of acute rheumatic fever. However, despite the predominance of these major manifestations of acute rheumatic fever, there can be significant overlap with other disorders such as Lyme disease, serum sickness, drug reactions, and post-Streptococcal reactive arthritis. This overlap between disease processes has led to continued investigation of the pathophysiology as well as development of new biomarkers and laboratory studies to aid in the diagnosis of acute rheumatic fever and distinction from other disease processes.

  11. Etiología de la insuficiencia mitral pura en Costa Rica: estudio ecocardiográfico

    Esquivel M. Lidieth


    series internacionales. La causa isquémica ocupó el tercer lugar. La mayoría de los casos fueron leves a moderadas y de los casos con insuficiencia mitral severa, se dió la misma proporción.Introduction: International studies have demonstrated that mitral valve mixoid degeneration and coronary artery disease are the most frequent causes of pure mitral regurgitation. This cardiac ultrasound study was designed to know each cause prevalence in Costa Rica. Methods: We included all patients referred to our institution since July 1998 to July 2000 in whom was detected organic pure mitral regurgitation. We performed M-mode and bidimensional imaging and pulsed, continuous and colour flow mapping exploration. We classified patients in rheumatic disease, mixoid degenerative changes, secondary to coronary artery disease, to accelerated degenerative changes, to endocarditis, to collagen disease or other, regarding international criteria. We also assessed severity of mitral regurgitation classifying it in mild, moderate and severe. Results: We studied 82 patients, 48 females (59.7% and 34 males (37.8% between 14 and 87 years old (mean 50.3 +/- 20.7. There were 27 patients with pure mitral regurgitation of rheumatic origin (32.9%, 25 with mixoid degenerative valve disease (30.5%, 12 with coronary artery disease (14.6%, 9 with age-related changes (11%, 4 with mitral annulus elongation secondary to dilated cardiomyopathy not previously suspected (4.9%, 2 with systemic lupus erythematosus valve involvement (2.4%, 2 with no obvious cause (2.4% and one with endocarditis (1.2%. Sixty-two cases had mild or moderate mitral regurgitation (76.7% and 18 severe (21.9%. Sixty-one patients had left ventricle systolic function preserved (75.6% and 21 with some degree of diminished function. Conclusion: In this study we find a similar prevalence of rheumatic disease and mixoid degenerative disease as most frequent causes of mitral regurgitation, a fact different from international series

  12. Traumatic Mitral Valve and Pericardial Injury

    Nissar Shaikh


    Full Text Available Cardiac injury after blunt trauma is common but underreported. Common cardiac trauma after the blunt chest injury (BCI is cardiac contusion; it is very rare to have cardiac valve injury. The mitral valve injury during chest trauma occurs when extreme pressure is applied at early systole during the isovolumic contraction between the closure of the mitral valve and the opening of the aortic valve. Traumatic mitral valve injury can involve valve leaflet, chordae tendineae, or papillary muscles. For the diagnosis of mitral valve injury, a high index of suspicion is required, as in polytrauma patients, other obvious severe injuries will divert the attention of the treating physician. Clinical picture of patients with mitral valve injury may vary from none to cardiogenic shock. The echocardiogram is the main diagnostic modality of mitral valve injuries. Patient’s clinical condition will dictate the timing and type of surgery or medical therapy. We report a case of mitral valve and pericardial injury in a polytrauma patient, successfully treated in our intensive care unit.

    Aceves-Avila, F J; Fraga, A


    The medical texts published in New Spain between the XVI and XVIII century have not been searched until now for evidence of the existence of rheumatoid arthritis and other rheumatic diseases before the descriptions made by Sydenham. We surveyed most of the medical books written and published in New Spain from the arrival of the Spaniards to the XVIII century, and we divided the diseases with articular manifestations into four groups, according to their main clinical characteristics: pain without swelling in anatomical region; pain without swelling in several joints; pain and swelling in joints, and joint complaints associated with contagious diseases. We found that a difference was established between gout and rheumatoid arthritis one hundred years before Sydenham, according to the different evolutions of both diseases, and we present one of the oldest descriptions of reactive arthritis.

    Full Text Available Autoimmune reactions are of primary importance in the development of extrahepatic manifestations of viral hepatitis, among which there are rheumatic symptoms and syndromes. The incidence of clinically significant extrahepatic manifestations is shown to be relatively low, but they may be in the foreground in the clinical picture of the disease and are noted for severity. It is concluded that due to the high prevalence of hepatitis and the systemic pattern of their chronic forms, patients with extrahepatic manifestations of viral hepatitis may be encountered in the practice of a therapist and a rheumatologist. The onset of the infection caused by hepatitis viruses may be accompanied by articular lesion therefore the rheumatologist may be the first physician such a patient may resort to.

  16. Social implications of rheumatic diseases.

    Kłak, Anna; Raciborski, Filip; Samel-Kowalik, Piotr


    Social consequences of a disease constitute limitations in performing roles relating to working life as well as family and social life caused by the disease, mainly chronic. The aim of the study was to analyze the social consequences of rheumatic diseases in the aspect of disability pensions with respect to incapacity for work and quality of life. The occurrence of rheumatic diseases is related not only to increased risk of different types of organic changes, but above all disability. In Europe almost 50% of persons suffering from diseases of the musculoskeletal system who are currently unemployed were breadwinners. Nearly 60% of them received legal disability status. The loss of work ability is, among other things, the consequence of progressive disability. In Europe 40% of persons suffering from rheumatoid arthritis (RA) had to stop working due to the disease. Most of the persons diagnosed with RA were of working age. It results in the decrease in the quality of life as well as economic difficulties (decreased incomes and increased disease-related costs). In Poland the results of the analysis of the Social Insurance Institution (ZUS) of first-time disability recognition issued for the purpose of disability pensions in 2014 showed that the incapacity for work was caused by diseases relating to general health condition (65.5%). Diseases of the musculoskeletal system were the cause of partial inability to work of 21.6% of persons who received a disability pension for the first time (as many as 5,349 certificates were issued). Early diagnosis and implementation of effective treatment are the necessary conditions for a patient to sustain activity, both professional and social, which is of crucial importance to reduce the negative effects of the disease.

  17. Dynamic heart phantom with functional mitral and aortic valves

    Vannelli, Claire; Moore, John; McLeod, Jonathan; Ceh, Dennis; Peters, Terry


    Cardiac valvular stenosis, prolapse and regurgitation are increasingly common conditions, particularly in an elderly population with limited potential for on-pump cardiac surgery. NeoChord©, MitraClipand numerous stent-based transcatheter aortic valve implantation (TAVI) devices provide an alternative to intrusive cardiac operations; performed while the heart is beating, these procedures require surgeons and cardiologists to learn new image-guidance based techniques. Developing these visual aids and protocols is a challenging task that benefits from sophisticated simulators. Existing models lack features needed to simulate off-pump valvular procedures: functional, dynamic valves, apical and vascular access, and user flexibility for different activation patterns such as variable heart rates and rapid pacing. We present a left ventricle phantom with these characteristics. The phantom can be used to simulate valvular repair and replacement procedures with magnetic tracking, augmented reality, fluoroscopy and ultrasound guidance. This tool serves as a platform to develop image-guidance and image processing techniques required for a range of minimally invasive cardiac interventions. The phantom mimics in vivo mitral and aortic valve motion, permitting realistic ultrasound images of these components to be acquired. It also has a physiological realistic left ventricular ejection fraction of 50%. Given its realistic imaging properties and non-biodegradable composition—silicone for tissue, water for blood—the system promises to reduce the number of animal trials required to develop image guidance applications for valvular repair and replacement. The phantom has been used in validation studies for both TAVI image-guidance techniques1, and image-based mitral valve tracking algorithms2.

  18. Echocardiographic determinants of mitral early flow propagation velocity.

    Barbier, Paolo; Grimaldi, Antonio; Alimento, Marina; Berna, Giovanni; Guazzi, Maurizio D


    Transmitral color Doppler early diastolic flow propagation velocity (Vp) has been correlated with the left ventricular (LV) relaxation time constant tau in dilated cardiomyopathy and ischemic heart disease. The aim of this study was to investigate the independent influence of LV systolic function and geometry, and of LV relaxation, on Vp in an unselected outpatient population. We studied 30 normal subjects and 130 patients (hypertensive LV hypertrophy, aortic valve stenosis or prosthesis, hypertrophic cardiomyopathy, coronary artery disease, dilated cardiomyopathy, aortic or mitral valve regurgitation). In all, we noninvasively measured LV geometry, mass, systolic function, wall motion dyssynergy, and diastolic function (abnormal relaxation or restrictive LV Doppler filling patterns). The Vp was similar in normal subjects and in patients (51 +/- 14 vs 53 +/- 25 cm/s). In normal subjects, the determinants of Vp at multiple regression analysis were isovolumic relaxation time, 2-dimensional cardiac index, and mitral E-wave velocity-time integral. In all, the main determinants were LV ejection fraction, percent of segmental wall dyssynergy, and isovolumic relaxation time and age. The Vp was highest in hypertrophic (75 +/- 25 cm/s, p <0.05 vs normal subjects) and lowest in dilated (35 +/- 13 cm/s, p = NS) cardiomyopathy. During multivariate analysis of variance, percent of wall dyssynergy (but not diffuse LV hypokinesia) independently reduced Vp (p = 0.02). The latter was not influenced by the LV filling pattern. Thus, in an unselected clinical population, prolonged relaxation per se does not influence Vp if LV systolic dysfunction and/or wall dyssynergy is absent-the latter factors are important independent determinants of Vp, which is determined by multiple factors.

  19. Left atrial ball valve thrombus

    R. Balaji


    Full Text Available "Ball valve thrombus" which is a spherical free floating clot in left atrium is an often quoted, but uncommonly encountered complication in patients with severe mitral stenosis of rheumatic origin, who are in atrial fibrillation. We describe the case of a 31-year-old lady with rheumatic heart disease, severe mitral stenosis and moderately severe aortic stenosis who had undergone closed mitral valvotomy 13 years ago. The patient presented with an episode of non-exertional syncope and breathlessness on exertion of 6 months duration and was in normal sinus rhythm. Echocardiography facilitated ante-mortem diagnosis and prompt institution of surgery was life saving.

  20. Mitral Valve Replacement with Half-and-Half Technique for Recurrent Mitral Paravalvular Leakage.

    Morisaki, Akimasa; Kato, Yasuyuki; Takahashi, Yosuke; Shibata, Toshihiko


    Reoperation for paravalvular leakage can cause recurrent paravalvular leakage through severe damage to the mitral annulus. Previously, mitral valve replacement using a half-and-half technique for extensive mitral annular calcification was reported; here, application of the technique to treat recurrent paravalvular leakage is described. A 78-year-old male with three prior mitral valve replacements developed recurrent paravalvular leakage, for which he had undergone his third mitral valve replacement at the age of 69 years. On this occasion, a mechanical valve with circumferential equine pericardial patch reinforcement of the annulus had been used. Five years later, the patient developed hemolytic anemia and congestive heart failure due to recurrent paravalvular leakage. Intraoperatively, broad dehiscence was seen between the prosthetic valve and mitral annulus at two sites, the anterior and posterior commissures, without infection. A fourth mitral valve replacement was performed with a St. Jude Medical valve, using a half-and-half technique. This entailed the use of non-everting mattress sutures on the anterior half of the annulus, and everting mattress sutures on the left atrial wall around the posterior half of the annulus. Extensive annular defects required reinforcement of the posterior mitral annulus with a bovine pericardial patch. Postoperative echocardiography showed no paravalvular leakage. The half-and-half technique may be useful in treating recurrent paravalvular leakage of the mitral valve.

  1. Mitral Valve Replacement with a Mechanical Valve for Severe Mitral Regurgitation in a Small Dog

    Daisuke Taguchi


    Full Text Available A seven-year-old Shih Tzu with refractory repeated pulmonary edema and syncope was presented for surgical operation. From the results of cardiovascular examinations, the dog was diagnosed as severe mitral regurgitation (ACVIM consensus class D and mild tricuspid regurgitation. The dog first underwent surgery with mitral valve plasty; however, the results were unsatisfactory due to severe damage of the whole mitral valve. The operation was quickly changed to mitral valve replacement using a mechanical valve (19 mm. The dog survived surgery and lived for 2 years and one month after operation using long-term anticoagulant (warfarin therapy in spite of several thrombosis-related events.

  2. Edge-to-edge chordal transfer repair for anterior leaflet prolapse of mitral valve in 21 patients

    ZHANG Jian-qun; CHI Li-qun; KONG Qing-yu; ZHENG Si-hong; XIAO Wei


    Background Repair of anterior mitral leaflet (AML) prolapse is still a technical challenge for cardiac surgeons. It is an important issue to find a way to repair the AML prolapse with a reliable and reproducible technique.Methods Between January 2002 and June 2009, the operation of chordal transfer based on the "edge-to-edge"technique was performed in 21 patients with serious mitral valve regurgitation because of prolapse of the anterior leaflet.After the operation, echocardiography was performed in each patient before discharge and at the time of follow-up.Results All patients survived the operation. One patient required mitral valve replacement because of anterior leaflet perforation 3 days after the operation. The other patients were free from reoperation. At the time of follow-up, all these patients were in New York Heart Association (NYHA) functional class I. In all these patients, pre-discharge and follow-up echocardiography showed neither stenosis nor significant regurgitation of the mitral valve: the cross-sectional area of the mitral valve was 3.3-4.8 cm2 (mean (3.78:±0.52) cm2), the mean regurgitation area was (0.45:±0.22) cm2. At the same time, both dimension of left atrium and left ventricle reduced significantly (left atrium diameter: pre-operation (48.26±11.12) mm, post-operation (37.57±9.56) mm, P <0.05; the end-diastolic diameter of the left ventricle:pre-operation (61.43±8.24) mm, post-operation (42.35±10.79) mm, P<0.01).Conclusion "Edge-to-edge" chordal transfer technique is a simple, reliable, and reproducible technique that can provide good results for repair of anterior leaflet prolapse of mitral valve.

  3. [Surgical techniques in mitral valve diseases. Reconstruction and/or replacement].

    Noack, T; Mohr, F-W


    Mitral valve (MV) disease is one of the most common heart valve diseases. The surgical and interventional treatment for MV disease requires a multidisciplinary approach. For primary mitral valve regurgitation (MVR) surgical MV repair is the treatment of choice, which can be performed with an excellent outcome and long-term survival in reference centers. The surgical technique used for MV repair depends on the pathological mechanism, the morphological dimensions of the MV, the operative risk and the expertise of the cardiac surgeon. The surgical and interventional treatment of secondary MVVR is the subject of on-going discussions. In patients with moderate secondary MVR undergoing coronary artery bypass grafting, concomitant MV repair should be performed. In the presence of severe secondary MR with risk factors for failure of MV repair, patients should consider having MV replacement. In the rare cases of patients presenting with mitral valve stenosis (MVS) MV repair can be considered in young patients and who are most often treated with MV replacement. The choice between biological or mechanical MV replacement depends on the pathophysiology, the comorbidities, the amount of anticoagulation necessary and the age of the patient. New percutaneous techniques for MV replacement offer new treatment options for reoperation in high-risk patients.

  7. Mitral Annular Kinetics, Left Atrial and Left Ventricular Diastolic Function Post Mitral Valve Repair in Degenerative Mitral Regurgitation

    Chun eSchiros


    Full Text Available Objective: The relationship of mitral annular (MA kinetics to left ventricular (LV and left atrial (LA function before and after mitral valve repair has not been well studied. Here we sought to provide comprehensive analysis that relates to MA motions, LA and LV diastolic function post mitral valve repair. Methods: Three-dimensional analyses of mitral annular motion, LA function and LV volumetric and diastolic strain rates were performed on 35 degenerative mitral regurgitation (MR patients at baseline and 1-year post mitral valve repair, and 51 normal controls, utilizing cardiac magnetic resonance imaging with tissue tagging. Results: All had normal LV ejection fraction (EF at baseline. LV and LA EFs decreased 1-year post-surgery vs. controls. LV early-diastolic myocardial strain rates decreased post-surgery along with decreases in normalized early-diastolic filling rate, E/A ratio and early-diastolic MA relaxation rates. Post-surgical LA late active kick remained higher in MR patients vs. control. LV and LA EFs were significantly associated with peak MA centroid to apex shortening. Furthermore, during LV systolic phase, peak LV ejection and LA filling rates were significantly correlated with peak MA centroid to apex shortening rate, respectively. While during LV diastolic phase, both peak early diastolic MA centroid to apex relaxation rate and LA ejection rate were positively significantly associated with LV peak early diastolic filling rate. Conclusions— MA motion is significantly associated with LA and LV function. Mitral annular motion, left atrial function and left ventricular diastolic strain rates are still impaired one year post mitral valve repair. Long term effects of these impairments should be prospectively evaluated.

  8. [Music for rheumatism--a historical overview].

    Evers, S


    The history of the use of music to lessen the pain of rheumatism is seen in the use of musical therapy in medicine as a whole. Sources citing the use of music specifically in rheumatism are rare; often, rather than rheumatism, terms like "gout (podagra)" or "joint-pain" are mentioned. This is connected with the obscure and pathognomic perceptions of rheumatism. In the archeo-medicine and for primitive cultures the considered potency of music was primarily dominated by animistic thinking. In antiquity humoral pathology developed a philosophy that tried to explain the benefits of music, even for rheumatism, but found little acceptance. In the Middle Ages and in the Baroque period iatromechanistic conceptions determined music as useful in fight against pain. In the Romantic period there was speculation about music as a causal therapy, but it was shortlived. In the 20th century music is applied as an active therapy in the care of persons suffering from rheumatism; its empiric success as a remedy in rehabilitative and palliative therapy is recognized.

  9. Persisting eicosanoid pathways in rheumatic diseases.

    Korotkova, Marina; Jakobsson, Per-Johan


    An unmet clinical need exists for early treatment of rheumatic diseases and improved treatment strategies that can better maintain remission with reduced ongoing subclinical inflammation and bone destruction. Eicosanoids form one of the most complex networks in the body controlling many physiological and pathophysiological processes, including inflammation, autoimmunity and cancer. Persisting eicosanoid pathways are thought to be involved in the development of rheumatic diseases, and targeting this pathway might enable improved treatment strategies. Several enzymes of the arachidonic acid cascade as well as eicosanoid receptors (all part of the eicosanoid pathway) are today well-recognized targets for anti-inflammatory drugs that can reduce symptoms of inflammation in rheumatic diseases. In this Review, we outline the evidence supporting pivotal roles of eicosanoid signalling in the pathogenesis of rheumatic diseases and discuss findings from studies in animals and humans. We focus first on rheumatoid arthritis and discuss the upregulation of the cyclooxygenase and lipoxygenase pathways as most data are available in this condition. Research into the roles of eicosanoids in other rheumatic diseases (osteoarthritis, idiopathic inflammatory myopathies, systemic lupus erythematosus and gout) is also progressing rapidly and is discussed. Finally, we summarize the prospects of targeting eicosanoid pathways as anti-inflammatory treatment strategies for patients with rheumatic diseases.

  10. Cutting edge issues in rheumatic fever.

    Chang, Christopher


    Although the incidence of acute rheumatic fever and rheumatic heart disease has decreased significantly in regions of the world where antibiotics are easily accessible, there remains a high incidence in developing nations as well as in certain regions where there is a high incidence of genetic susceptibility. These diseases are a function of poverty, low socioeconomic status, and barriers to healthcare access, and it is in the developing world that a comprehensive prevention program is most critically needed. Development of group A streptococcal vaccines has been under investigation since the 1960s and 50 years later, we still have no vaccine. Factors that contribute to this lack of success include a potential risk for developing vaccine-induced rheumatic heart disease, as well as difficulties in covering the many serological subtypes of M protein, a virulence factor found on the surface of the bacterium. Yet, development of a successful vaccine program for prevention of group A streptococcal infection still offers the best chance for eradication of rheumatic fever in the twenty-first century. Other useful approaches include continuation of primary and secondary prevention with antibiotics and implementation of health care policies that provide patients with easy access to antibiotics. Improved living conditions and better hygiene are also critical to the prevention of the spread of group A streptococcus, especially in impoverished regions of the world. The purpose of this article is to discuss current and recent developments in the diagnosis, pathogenesis, and management of rheumatic fever and rheumatic heart disease.

    To investigate the relationship between severity of cerebrovascular atherosclerosis stenosis and that of coronary atherosclerosis stenosis.Methods Cerebral angiography and coronary angiography were performed in 34 patients who had coronary disease with cerebral ischemia.Patients were divided into 3 subgroups according to the degree ofstenosis on angiography,concomitant diseases,risk factors and biochemical data.Results The follow-up study showed that the incidence of cardiac and cerebrovascular death increased significantly in patients with moderate to severe stenosis of coronary and cerebral arteries;the severity of stenosis in the coronary artery parallels that in the solitary carotid artery,or dual carotid and vertebral arteries.Conclusions Patients with coronary and cerebral artery stenosis,especially those with multi-risk factors,such as hypertension,diabetes and cigarette smoking,should receive intensive treatment to reduce cardiac and cerebrovascular events.(J Geriatr Cardiol 2008;5:227-229)

  12. [Idiopathic progressive subglottic stenosis].

    Sittel, C


    Idiopathic subglottic stenosis is causing a narrowing of the central airway at the laryngotracheal junction. Etiology is remaining unclear at large. There is a marked preponderance for women in the fertile age, an association to estrogene or progesterone metabolism remains doubtful. Suggested treatment varies from repeated endoscopic interventions to primary open resection. Therapy selection in this heterogeneous condition should be based on the individual patient situation as well as surgeon's expertise. This complex entity is prone to complications and should preferably be managed in a referral center.

  13. Subglottic tracheal stenosis

    Venuta, Federico; Rendina, Erino Angelo


    Benign subglottic stenosis represents a major therapeutic challenge. Interventional bronchoscopic treatment has a limited role in this setting due to anatomical and technical reasons. The benefit with these techniques is generally temporary, due to frequent recurrences, need for repeated procedures and risk of extending the area of damage. Laryngotracheal resection is at present the curative treatment of choice. Literature data show that surgical treatment may allow very high success rates at long term with low perioperative morbidity and mortality. Technical aspects and results are reported and discussed.

  14. 3D printed cardiac phantom for procedural planning of a transcatheter native mitral valve replacement

    Izzo, Richard L.; O'Hara, Ryan P.; Iyer, Vijay; Hansen, Rose; Meess, Karen M.; Nagesh, S. V. Setlur; Rudin, Stephen; Siddiqui, Adnan H.; Springer, Michael; Ionita, Ciprian N.


    3D printing an anatomically accurate, functional flow loop phantom of a patient's cardiac vasculature was used to assist in the surgical planning of one of the first native transcatheter mitral valve replacement (TMVR) procedures. CTA scans were acquired from a patient about to undergo the first minimally-invasive native TMVR procedure at the Gates Vascular Institute in Buffalo, NY. A python scripting library, the Vascular Modeling Toolkit (VMTK), was used to segment the 3D geometry of the patient's cardiac chambers and mitral valve with severe stenosis, calcific in nature. A stereolithographic (STL) mesh was generated and AutoDesk Meshmixer was used to transform the vascular surface into a functioning closed flow loop. A Stratasys Objet 500 Connex3 multi-material printer was used to fabricate the phantom with distinguishable material features of the vasculature and calcified valve. The interventional team performed a mock procedure on the phantom, embedding valve cages in the model and imaging the phantom with a Toshiba Infinix INFX-8000V 5-axis Carm bi-Plane angiography system. Results: After performing the mock-procedure on the cardiac phantom, the cardiologists optimized their transapical surgical approach. The mitral valve stenosis and calcification were clearly visible. The phantom was used to inform the sizing of the valve to be implanted. Conclusion: With advances in image processing and 3D printing technology, it is possible to create realistic patientspecific phantoms which can act as a guide for the interventional team. Using 3D printed phantoms as a valve sizing method shows potential as a more informative technique than typical CTA reconstruction alone.

    BACKGROUND: Smaller observational studies have suggested familial clustering of mitral regurgitation (MR). Using a large twin cohort, the aims were to assess MR concordance rates and assess mortality in MR twins and unaffected cotwins. METHODS: Through the Danish Twin Registry, twins...... with an International Classification of Diseases, Eighth Revision and Tenth Revision diagnosis code of MR born 1880-1989 were identified and proband-wise concordance rates were calculated. To assess whether having a cotwin with MR affected survival, 10 matched twins without MR (n = 5,575) were selected for each MR twin...... (n = 562), and all-cause mortality rates were assessed. RESULTS: Among the 87,432 twins alive January 1, 1977, or later, 494 (0.57%) MR individuals were identified. Six MR concordant pairs were found, of which 3 were monozygotic. Proband-wise concordance rate when accounting for right censoring...

    Full Text Available The mitral valve prolapse (MVP is one of the most inconsistent diagnose. In the most cases patients with MVP have the good long-term prognosis, and therapy is aimed at reduction in psychovegetative dysfunction.

    Poststreptococcal complications, such as acute rheumatic fever (ARF) and rheumatic heart disease (RHD), are common in resource-limited settings, with RHD recognised as the most common cause of paediatric heart disease worldwide. Managing these conditions in resource-limited settings can be challenging. We review the investigation and treatment options for ARF and RHD and, most importantly, prevention methods in an African setting.

    Papanagiotou, P.; Boutchakova, M. [Klinikum Bremen-Mitte/Bremen-Ost, Klinik fuer Diagnostische und Interventionelle Neuroradiologie, Bremen (Germany)


    Spinal stenosis is a narrowing of the spinal canal by a combination of bone and soft tissues, which can lead to mechanical compression of spinal nerve roots or the dural sac. The lumbal spinal compression of these nerve roots can be symptomatic, resulting in weakness, reflex alterations, gait disturbances, bowel or bladder dysfunction, motor and sensory changes, radicular pain or atypical leg pain and neurogenic claudication. The anatomical presence of spinal canal stenosis is confirmed radiologically with computerized tomography, myelography or magnetic resonance imaging and play a decisive role in optimal patient-oriented therapy decision-making. (orig.) [German] Die Spinalkanalstenose ist eine umschriebene, knoechern-ligamentaer bedingte Einengung des Spinalkanals, die zur Kompression der Nervenwurzeln oder des Duralsacks fuehren kann. Die lumbale Spinalkanalstenose manifestiert sich klinisch als Komplex aus Rueckenschmerzen sowie sensiblen und motorischen neurologischen Ausfaellen, die in der Regel belastungsabhaengig sind (Claudicatio spinalis). Die bildgebende Diagnostik mittels Magnetresonanztomographie, Computertomographie und Myelographie spielt eine entscheidende Rolle bei der optimalen patientenbezogenen Therapieentscheidung. (orig.)

    Full Text Available The paper gives the data available in the literature on the role of opportunistic microorganisms (OMs in rheumatic diseases (RDs. OMs are anticipated to be involved as triggers initiating the development of chronic inflammation. Along with this, OMs in autoimmune diseases may play a defensive role through the interaction with Toll-like receptors and the activation of T cells that have suppressor activity. The possible involvement of OMs in the pathogenesis of RDs provides support not only the isolation of microorganisms, but also the detection of antibacterial antibodies of different classes. Of great importance are OMs in the etiology of comorbid infections, the risk of which is due to both the presence of autoimmune RDs and the necessity of using the drugs having immunosuppressive activity. The active clinical introduction of biological agents is followed by a rise in the rate and severity of different infections, including those caused by OMs. Having a marked biological and environmental plasticity, OMs are able to persist long when there are changes in the immune defense of patients with RDs. There is evidence for the higher adhesive properties and persistent potential of the microorganisms that colonize the body of patients with RDs. In the latter, OMs that are distinguished by pronounced antibiotic polyresistance are isolated, making the treatment and prevention of opportunistic infections more difficult in rheumatology. The results of the papers analyzed in the review suggest that the study of OMs in RDs is of practical importance.

  3. [Soft tissue rheumatism in erderly].

    Szczepański, Leszek


    Disorders of soft, peri-articular tissues are a common cause of musculoskeletal pain in elderly patients. Nevertheless, most physicians underestimate the role of soft tissue rheumatism in the pathomechanism of the pain. The impairments of soft tissue can not be diagnosed by X-rays examinations, whereas degenerative lesions of joints are easy diagnosed using this method even despite of their uncertain role in producing the symptoms. The incidence of pain syndromes originated from soft tissues differ regarding to the age of patients. In young subjects the incidence of all of them is generally low. Syndromes provoked by overloading during work: repetitive strain syndrome, canal tunnel syndrome, tennis elbow, golfers elbow, shoulder tendon coin disorders and myofascial pain syndrome are common in middle-aged patients. The morbidity of fibromialgia syndrome is also lower in old people probably as the result of diminished numbers and degenerative changes in nociceptive fibers. The syndromes prevailing in elderly patients include trochanteric syndrome and the pain syndromes provoked by muscle spasm depended on posture abnormalities. In the soft tissue pain syndrome prevention adapted to old age kinesitherapy and avoiding muscle overloading are recommended. Soft tissue pain syndromes are usually treated with non steroidal anti inflammatory drugs. In local pain syndromes better results can be obtained by local treatment. Local injections of glikocorticosteroids are usually very effective and safe.

    Full Text Available A estenose da válvula mitral é a lesão de válvula mais comum durante a gravidez. Apesar de um tratamento clínico eficaz e de uma anatomia valvular favorável, de acordo com o critério de Wilkins e Block [score de Wilkins-Block], a intervenção percutânea em pacientes sintomáticas mostra-se muito importante. Nessas pacientes, recomenda-se evitar ao máximo a exposição aos raios X para proteger o feto dos efeitos deletérios da radiação ionizante. Neste relato de caso, uma paciente de 24 anos, grávida, com grave estenose mitral (área valvular de 0,9 cm², foi submetida com sucesso a um tratamento percutâneo com ETE-guiado, sem o uso de raios X.Mitral valve stenosis is the most common valve lesion in pregnancy. In spite of an optimized clinical treatment and a favorable valve anatomy according to Wilkins and Block score, in symptomatic patients, percutaneous intervention is shown to be of great importance. In these patients, avoiding x-ray exposure as much as possible is recommended so as to protect the fetus from the deleterious effects of ionizing radiation. In this case report, a 24-year old pregnant patient with severe mitral stenosis (valve area of 0.9 cm² was successfully submitted to a TEE-guided percutaneous treatment, without the use of x-ray.

    Wen, Yun; Zeng, Zhiyu; Gui, Chun; Li, Lang; Li, Wenting


    Autoimmunity plays a critical role in the development of rheumatic heart disease (RHD). Recent studies have linked Th17 cells to the autoimmune mechanism associated with RHD. This study aimed to investigate changes in Th17 cell-related cytokine expression in acute and chronic RHD. We established a Lewis rat model of experimental RHD, which was induced by inactivated Group A streptococci and complete Freund's adjuvant. After 7- and 24-week intervention treatments, we measured serum levels of interleukin-17 (IL-17) and IL-6, key cytokines associated with Th17 cells, using a Luminex liquichip method, and levels of IL-17 and IL-6 in heart tissues using immunohistochemical assays. Moreover, expression levels of IL-17, IL-21, IL-6, and IL-23 in mitral valve tissues of human RHD patients were also measured using immunohistochemistry. Compared with the normal control group, serum IL-17 and IL-6 concentrations were significantly increased, and the expression levels of IL-17 and IL-6 in the mitral valve were also significantly increased in 7- or 24-week RHD rats (P<.017). Compared with the control group, expression of IL-17, IL-21, IL-6, and IL-23 in mitral valve tissues was significantly increased in RHD patients (P<.05). Our study suggested that the increased expression of Th17 cell-associated cytokines might play an important role in the pathogenesis and development of RHD. Copyright © 2015 Elsevier Inc.

    Background Previous studies have investigated the technique of linear ablation at the mitral isthmus (MI) in patients with idopathic atrial fibrillation (AF), but MI ablation in patients with prosthetic natural mitral valves (MVs) was not described in detail. Present study sought to summarize our initial experience of ablating MI in patients with prosthetic MVs Methods Patients with drug refractory AF and prosthetic MVs were eligible for this study, and the patients with natural MVs but received MI ablation served as control group. Left atrium (LA) mapping and ablation was carried out guided by CARTO system. The anatomy of MI was assessed via computer topography scan.Results During the study period, a consecutive of 19 patients (male/female=12/7, mean age of (48±-6) years) with prosthetic MVs (16 with metal valves, 3 with biologic valves) entered for AF ablation, other 35 patients served as control group. In study group, mapping along MI documented lower voltages ((2.0±1.0) vs. (3.1±1.3) mV, P=0.002), more fragmented potentials (19/19 vs. 20/15, P<0.001 ), and higher impedance ((132±34) vs. (110±20) Ω, P=0.004). After initial ablation, more residual gaps along the MI lesions were found in study group (2.4±0.4 vs. 1.7±0.3, P <0.001). The mean length of MI ((6.2±3.3) vs. (7.1±2.3) cm, P=0.25) was comparable between 2 groups, but the MI in study group was much thicker ((3.1 ±1.8) vs. (2.1±1.07) cm, P=0.01 ) and all were found as pouch type (19/19 vs. 2/35, P <0.001). The follow-up results were comparable (65.1% vs. 72.3%, P=0.30).Conclusion For patients with prosthetic MVs, linear ablation at MI could be successfully carried out despite anatomical and pathological changes.

  7. Anterior Mitral Leaflet Augmentation for Ischemic Mitral Regurgitation Performed Via a Right Thoracotomy Approach.

    Mihos, Christos G; Pineda, Andres M; Horvath, Sofia A; Santana, Orlando


    Ischemic mitral regurgitation (MR) after myocardial infarction is associated with poor long-term survival, and the optimal treatment strategy remains debated. The most common repair technique used is a restrictive annuloplasty. However, up to 15% to 30% of patients experience recurrent MR owing to progressive left ventricular remodeling and geometric distortion of the mitral valve apparatus. Anterior mitral leaflet augmentation using a pericardial patch, in combination with a true-sized mitral annuloplasty, has been proposed as an adjunctive technique to increase the durability of valve repair for ischemic MR. Herein, we describe 2 cases of anterior mitral leaflet augmentation with annuloplasty repair for severe ischemic MR via a minimally invasive right thoracotomy, and review the literature regarding patient selection and clinical outcomes of this technique.

    Ali, Sulafa Khalid Mohamed; Eldaim, Inaam Noor; Osman, Samia Hassan; Bakhite, Sahar Mohamed


    Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) constitute important public health problems in developing countries. Children with ARF and RHD seen at Children's Hospital-Sudan from May 2008-2009 were examined clinically and by echocardiography. Blood cytokines (interleukin 10 (IL10), Tumor necrosis factor alpha (TNF- alpha) and interferon gamma (IFN-gamma) were done. Thirty six children were enrolled; 63% had established RHD, and 37% ARF. Mitral regurgitation (MR) was the most common lesion (94%).Ninety five percent of the valve lesions were severe. The serum interleukin IL10 level ranged between 3-6 pg/ml. TNF alpha levels were 9- 100 pg/ml in 12 patients (40%), 101-1000 pg/ml in 10 patients (33%), more than 1000 in 8 patients (26%). The level of IFN gamma ranged between 2-7 pg/m in all patients except 2 (84 and 135 pg/ml). RHD is manifested with severe valvular lesions and a high TNF alpha indicating and ongoing inflammation.

    Francisco Díaz Ramírez


    Full Text Available Resumen: La valvuloplastia con globo es ampliamente aceptada como tratamiento de elección de la estenosis aórtica congénita en recién nacidos y lactantes. Las complicaciones por el procedimiento son bien conocidas pero el daño valvular mitral es infrecuente. Se presenta un paciente masculino, de siete meses de edad, con el diagnóstico de coartación de la aorta y estenosis valvular aórtica a quién se le realizó dilatación de ambas lesiones por cateterismo intervencionista. A las 20 horas del procedimiento se diagnosticó insuficiencia cardíaca grave secundaria a lesión de la valva anterior mitral. Se intervino quirúrgicamente de urgencia y se observó un desgarro en forma de hendidura desde el borde libre hasta el anillo, el cual se reparó y se realizó anuloplastia en la comisura lateral. En el postoperatorio inmediato evolucionó sin complicaciones y al año de seguimiento presenta insuficiencia valvular mitral leve sin signos de recoartación ni de estenosis valvular aórticas. / Abstract: Balloon valvuloplasty is widely accepted as the treatment of choice for congenital aortic stenosis in newborns and infants. Complications from the procedure are well known but mitral valve damage is rare. This is the case of a 7-month-old male patient with the diagnosis of coarctation of the aorta and aortic valve stenosis who underwent dilation of both lesions via catheterization. At 20 hours of the procedure a severe heart failure secondary to an injury of the anterior mitral valve was diagnosed. The patient underwent emergency surgery and a slit-like tear from the free edge to the annulus was observed, which was repaired and annuloplasty in the lateral commissure was performed. In the immediate postoperative period the patient progressed without complications and at one year follow up he shows mild valve regurgitation without evidence of recoarctation or aortic valve stenosis.

  10. Interaction of pregnancy and autoimmune rheumatic disease.

    Østensen, Monika; Villiger, Peter M; Förger, Frauke


    During pregnancy, the fetus represents a natural allograft that is not normally rejected. While the maternal immune system retains the ability to respond to foreign antigens, tolerance mechanisms are up-regulated to protect the fetus from immunologic attacks by the mother. The profound immunologic adaptations during and after pregnancy do influence maternal autoimmune rheumatic diseases in several ways. One is triggering the onset of a rheumatic disease in the post partum period, the other influencing disease activity of established rheumatic disease. The review will discuss the mechanisms of increased susceptibility of rheumatoid arthritis (RA) in the first year post partum with a specific emphasis on the role of fetal cells or antigens persisting in the maternal circulation (so called microchimerism). Furthermore, the different influences of pregnancy on established rheumatic diseases will be highlighted. A marked beneficial effect of pregnancy is observed on RA whereas several other rheumatic diseases as ankylosing spondylitis (AS) and systemic lupus erythematosus (SLE) show either no particular effect or an aggravation of symptoms during pregnancy. Differences emerging in regard to modulation of disease symptoms during pregnancy seem related to response to hormones, the type of cytokine profile and immune response prevailing as well as further downstream interactions of molecular pathways that are important in disease pathogenesis.

    Guadalajara, J F; Gual, J J; Valvuena, N; Vera, A; Laplaza, I; Salinas, L


    The histologic findings of 325 necropsies of rheumatic patients at the National Institute of Cardiology in Mexico, between 1980-1985 were studied forty five of them had Aschoff nodules plus valvular inflammation-Out of these 45 cases two groups were formed: children-adolescent group (24 cases) and an adult group (21 cases). The clinical, histologic and laboratory findings were compared. Clinical records were reviewed searching for history of rheumatic fever. Active rheumatic fever was suspected in 16 patients in the younger group (67%) and only in 3 adults (14.2%). As far as Jones' criteria is concerned, the most common finding was carditis, principally in the younger group (83%). In the adult group, it appeared in 50% of the patients. All other criteria were only occasionally seen or could not be identified during the patients lifetime. The most common laboratory finding which could suggest active rheumatic fever were: a high levels of anti-streptolysin in younger patients (95%) and elevation of erythro-sedimentation in adults (83%). We conclude that in active rheumatic fever of the adult; Jones criteria are not met, so the illness is difficult to recognize, and there is clinical-histologic discrepancy. In this context the disease has a "silent" evolution.

  12. "Vanishing" pulmonary valve stenosis

    Nofil I Arain


    Full Text Available Objective: Both spontaneous resolution and progression of mild pulmonary valve stenosis (PS have been reported. We reviewed characteristics of the pulmonary valve (PV to determine factors that could influence resolution of mild PS. Methods: Fifteen asymptomatic pediatric patients with spontaneous resolution of isolated mild PS were retrospectively reviewed. Results: There was no correlation between the PV gradient, clinical presentation, age at diagnosis, or PV morphology. The PV annulus was small at initial presentation, which normalized at follow up. When corrected for the body surface area (z-score, the PV annulus was normal in all patients, including at initial evaluation. Conclusions: Based on our observation, neither age at diagnosis, nor PV-morphology-influenced resolution of mild PS. The variable clinical presentation makes it difficult to categorize and observe mild PS by auscultation alone. The PV annulus z-score could be a useful adjunct to determine the course and serial observation of mild PS.

    To evaluate the usefulness of ultrasound in hypertrophic pyloric stenosis (HPS) and to analyse the correlation between the dimensions of the pyloric muscle and the age and the weight of the child, 34 children with suspected HPS and 34 controls were examined. An overlap between the dimensions...... of the pyloric muscle in the HPS group and in the controls stresses the need to assess the muscle length, the muscle diameter, and the muscle wall thickness in establishing the sonographic diagnosis of HPS. We found the following criteria useful: muscle length greater than or equal to 19 mm, muscle diameter...... greater than or equal to 10 mm, and muscle wall thickness greater than or equal to 4 mm. The results did not confirm previous reports of increasing dimensions of the pyloric muscle with age and weight....

  15. Sydenham's chorea and erythema marginatum as the first clinical presentation of acute rheumatic fever

    Farhang Babamahmoodi


    Full Text Available (Received 5 February, 2009 ; Accepted 13 Jan, 2010AbstractAcute rheumatic fever is an acute systemic disease due to autoimmune reaction against some of BHSA. Similarity between bacterial antigens and cardiaciovascular tissue, synovial membrane, joints and subcutaneous tissues and cerebral basal ganglions are the causes of autoimmune reactions and manifestation of the disease. Most of the ARF occur in children (5-14 years old followed by streptococcal pharyngitis and the disease is very rare in adults.Sydenham's chorea is a late manifestation of ARF and one of the John's diagnostic criteria that is usually revealed when the other criteria are absent. There is often a long latent period between clinical manifestations of the ARF and the onset of chorea as an uncommon initial presentation of acute rheumatic fever. We report the clinical findings, investigations and the course of clinical development of a seventeen-year-old girl, who presented with acute onset of abnormal involuntary movements in her right hand for two days before her admission. She had sore throat and fever three weeks before development of these new problems. Her complaints disappeared with proper treatment. The considerable findings in this case report was co-incidence of Sydenham's chorea with erythema marginatum, fever, severe mitral valve insufficiency, arthralgia in an adult patient that is a very rare case.

    Raymid García Fernández


    Full Text Available Antecedents and Objectives: The percutaneous mitral valvuloplasty is the procedure of choice in patients with mitral stenosis and an adequate valvular anatomy. The cases treated in Cuba were few until 1998, and the first ones were carried out by foreign medical professionals. This article aims at showing the results of the development of this technique in Cuba. Method: A total of 110 consecutive percutaneous mitral valvuloplasties were carried out in 107 patients (three of them were repeated due to restenosis at the Cuban Cardiology and Cardiovascular Surgery Institute, between June 17th 1998 and June 30th 2004 (106 using the Inoue method and 4 by Multi-track. The average evolution time was 24.6 months (72 maximum and 1,93 minimum. Results: Before the procedure, 94.54 percent of the patients were within the functional classification III and IV of the NYHA; after the procedure 96,36 percent were within functional classification I and II. Using the Wilkins score ≤ 8, average areas of 2,18 cm2 were obtained; and between 9 and 12, areas of 1,81 cm2. The initial success of the procedure was 96,36 percent, and without complications 92,72 percent. Mortality was 0,9 percent, survival 100 percent, and 91,74 percent of the patients were free from complications. As an adverse event in the follow-up it was determined a mitral reestenosis in 5 patients (4,54 %. The average stay in hospital was of 1,36 days. The savings concerning hospitalization was of $ 4136775.39. Conclusions: Percutaneous mitral valvuloplasty is a safe and effective method in patients with mitral stenosis; its results remain in the sort, medium or long run.

  17. The Mid-Term Results of Patients who Underwent Radiofrequency Atrial Fibrillation Ablation Together with Mitral Valve Surgery

    Abdurrahim Çolak

    Full Text Available Abstract Objetive: Saline-irrigated radiofrequency ablation, which has been widely used for surgical treatment of atrial fibrillation in recent years, is 80-90% successful in achieving sinus rhythm. In our study, our surgical experience and mid-term results in patients who underwent mitral valve surgery and left atrial radiofrequency ablation were analyzed. Methods: Forty patients (15 males, 25 females; mean age 52.05±9.9 years; range 32-74 underwent surgery for atrial fibrillation associated with mitral valvular disease. All patients manifested atrial fibrillation, which started at least six months before the surgical intervention. The majority of patients (36 patients, 90% were in NYHA class III; 34 (85% patients had rheumatic heart disease. In addition to mitral valve surgery and radiofrequency ablation, coronary artery bypass, DeVega tricuspid annuloplasty, left ventricular aneurysm repair, and left atrial thrombus excision were performed. Following discharge from the hospital, patients' follow-up was performed as outpatient clinic examinations and the average follow-up period of patients was 18±3 months. Results: While the incidence of sinus rhythm was 85.3% on the first postoperative day, it was 80% during discharge and 71% in the 1st year follow-up examination. Conclusion: Radiofrequency ablation is an effective method when it is performed by appropriate surgical technique. Its rate for returning to sinus rhythm is as high as the rate of conventional surgical procedure.

  18. Challenges to developing effective streptococcal vaccines to prevent rheumatic fever and rheumatic heart disease

    Sharma A


    Full Text Available Abhinay Sharma, D Patric Nitsche-SchmitzDepartment of Medical Microbiology, Helmholtz Center for Infection Research, Braunschweig, GermanyAbstract: Acute rheumatic fever is a sequela of Streptococcus pyogenes and potentially of Streptococcus dysgalactiae subsp. equisimilis infections. Acute rheumatic fever is caused by destructive autoimmunity and inflammation in the extracellular matrix and can lead to rheumatic heart disease, which is the most frequent cardiologic disease that is acquired in youth. Although effective treatments are available, acute rheumatic fever and rheumatic heart disease remain serious threats to human health, which affect millions and cause high economic losses. This has motivated the search for a vaccine that prevents the causative streptococcal infections. A variety of potential vaccine candidates have been identified and investigated in the past. Today, new approaches are applied to find alternative candidates. Nevertheless, several obstacles lie in the way of an approved S. pyogenes vaccine for use in humans. Herein, a subjective selection of promising vaccine candidates with respect to the prevention of acute rheumatic fever/rheumatic heart disease and safety regarding immunological side effects is discussed.Keywords: autoimmune disease, side effects, M protein vaccine, molecular mimicry, coiled-coil, collagen binding, PARF

    Garcia-Villarreal, Ovidio A; Fernández-Ceseña, Ernesto; Solano-Ricardi, Mercedes; Aguilar-García, Alma L; Vega-Hernández, Raquel; Del Angel-Soto, Gustavo


    We report the case of 23-year-old man with mitral valve regurgitation and Glanzmann thrombasthenia, who underwent mechanical mitral valve replacement. Warfarin therapy was devastating, causing bilateral hemothorax, pericardial effusion, gastrointestinal bleeding, and hematuria. Redo mitral valve replacement with a biological prosthesis was required to resolve this critical situation. To our knowledge, this is the first report of mitral valve replacement in Glanzmann thrombasthenia, highlighting the danger of oral anticoagulation in this pathology.

  1. Acute severe mitral regurgitation. Pathophysiology, clinical recognition, and management.

    DePace, N L; Nestico, P F; Morganroth, J


    Acute severe mitral regurgitation often goes unrecognized as an emergency requiring prompt, lifesaving treatment. Its causes, physical signs, natural history, echocardiographic features, and findings on chest roentgenography, electrocardiography, and nuclear scintigraphic scanning are reviewed. Acute severe mitral insufficiency can be differentiated from chronic severe mitral insufficiency by noninvasive two-dimensional echocardiography. M-mode echocardiography is a valuable tool in evaluating mitral prosthetic paravalvular regurgitation.

    Worldwide, rheumatic fever remains a significant cause of mitral valve insufficiency. It is responsible for approximately 90 % of early childhood valvular surgeries in Brazil. Elongated or flail chordae are frequently responsible and require surgical correction. The purpose of this study was to analyze and compare the histological tissues of the mitral valve chordae and the mechanical resistance generated by the chordae, both with and without the application of a high-power laser. Twenty normal porcine mitral valve chordae were measured and divided randomly into the following two groups: control group (not subjected to a high-power laser) and laser group (subjected to photonic irradiation). Laser surgery was performed under controlled conditions, using following parameters: λ = 980-nm wavelength, power = 3 W, and energy = 60 J. A mechanical test machine was used in combination with a subsequent histological study to measure chordae tensile properties. A histological analysis demonstrated a typical collagen bundle arrangement in the control group; however, under a particular reached temperature range (48), the collagen bundles assumed different arrangements in the laser group. Significant reductions in the chordae tendineae lengths and changes in their resistance in the laser group were observed, as these chordae exhibited less rigid fibers. The chordae tendineae of normal porcine valves subjected to a high-power laser exhibited its length reduction and less stiffness compared to the control group. A histological analysis of the laser treatment specimens demonstrated differences in collagen bundle spatial organization, following slight changes into tissue temperature.

  3. [Mitral surgery by superior biatrial septotomy].

    Saade, A; Delepine, G; Lemaitre, C; Baehrel, B


    The superior biatrial septotomy approach consists of two semicircular right atrial and septal incisions joined at the superior end of the interatrial septum and extended across the dome of the left atrium, allowing exposure of the mitral valve by reflecting the ventricular side using stay sutures. From 1991 to 1993, 81 patients underwent mitral valve surgery by this technic. Mitral valve operation was combined with other cardiac procedures in 30 patients (37%) and was performed as a second operation in 21 patients (25.9%). Duration of cardiopulmonary bypass and aortic occlusion was not significantly different from that of patients operated via a conventional left atrial approach. The five hospital deaths (6.2%) were not related to this operative approach. Only 2 patients (3.3%) with preoperative in sinus rythm were discharged in atrial fibrillation after operation. In one patient (1.6%), atrioventricular block appeared at late follow-up. There were no cases of bleeding, atrioventricular nodal dysfunction or intra-atrial shunting related to the approach. This approach provides excellent exposure of the mitral valve even in unfavorable situations such as a small left atrium, dense adhesions from previous procedures or a previously implanted aortic prosthesis, without damage to various cardiac structures due to excessive traction. No retractor or vena cava repair are required. These data support a wide application of the superior biatrial septotomy approach in mitral valve surgery.

    When radiography is performed in patients with mitral regurgitation, cardiogenic pulmonary edema is a typical finding; however, asymmetric pulmonary edema has also been reported. We describe the case of a patient in whom mitral valve regurgitation caused isolated pulmonary edema in the right upper lung. We include a discussion of pulmonary edema in conjunction with mitral regurgitation.

  5. [What is happening to acute rheumatic fever?].

    Stéphan, J L


    Rheumatic fever is an inflammatory disease of the heart, joints, central nervous system and subcutaneous tissues that develops after a nasopharyngeal infection by one of the group A beta-haemolytic streptococci. The pathogenesis remains an enigma. As the disease has been less florid and some of the more characteristic manifestations less common in developed countries, it has become more difficult to establish the diagnosis on clinical grounds. Rheumatic fever and its sequellae are still active in developing countries. Carditis is a dominant feature of this social disease. Renewed educational efforts concerning this preventable disorder are needed among both physicians and the public.

    Replacement of the mitral valve through a standard vertical left atriotomy in patients requiring both aortic and mitral valve replacement can be very difficult. This is especially true in patients who have undergone previous median sternotomy. Replacement of the mitral valve through the aortic root after excision of the aortic valve is described in two case reports. This is a convenient approach when traditional exposure of the mitral valve is impractical in patients requiring double valve re...

    王文广; 任琳; 杨红梅; 张晶; 张双月; 刘晓媛; 王庆胜


    The female patient of 44-years old suffered from rheumatic heart disease for 22 years, and had valve replacementbefore one year. She was on admission for chest pain, with cTnT 1 236 pg/ml. Coronary angiog-raphy showed 95% of stenosis in the left main artery. She was diagnosed with acute myocardial infarction. With the improvement of living standards, coronary heart disease was in younger trend. So we recommended that conventional coronary angiography was performed for women over 35-year before valve replacement in rheumatic heart disease.

  10. Cervical stenosis following electrosurgical conization

    Aparecida Cristina Sampaio Monteiro

    Full Text Available CONTEXT AND OBJECTIVE: Cervical stenosis is a postoperative complication of procedures for treating preinvasive lesions of the cervix and takes on particular importance due to the clinical repercussions associated with it. Furthermore, it causes limitations in relation to cytological and colposcopic follow-up. The aim here was to assess the incidence of cervical stenosis among a cohort of patients who underwent electrosurgical conization and to identify possible prognostic factors associated with its occurrence. DESIGN AND SETTING: Retrospective study at Gynecology and Obstetrics Department, Instituto Fernandes Figueira, Rio de Janeiro. METHODS:This was an observational study among a cohort of patients who underwent electrosurgical conization of the uterine cervix. The possible predictive variables were analyzed as bivariate means between the groups with and without stenosis. We also calculated the incidence density rate ratio for cervical stenosis in relation to each possible predictive variable and the respective confidence intervals (95%. Levels of 5% were considered significant. RESULTS: 274 patients who underwent electrosurgical conization of the uterine cervix with a minimum follow-up period of six months were included. The crude incidence of cervical stenosis was 7.66% and the incidence density was 3.3/1,000 patients-month. CONCLUSIONS: We did not find associations between the variables for stenosis. However, we observed borderline significance levels relating to hemorrhagic complications before and after the operation (p = 0.089.

  11. [Interventional mitral valve replacement. Current status].

    Lutter, G; Frank, D


    Approximately 30 % of patients suffering from severe valvular heart disease, such as mitral valve regurgitation are non-compliant to the gold standard of minimally invasive surgery, reconstruction or valve replacement. The number of these mostly old patients with severe comorbidities is increasing; therefore, transcatheter interventions have been developed to address an unmet clinical need and may be an alternative therapeutic option to the reference standard. Apart from the successful MitraClip therapy, alternative transcatheter reconstruction technologies are being developed. As with transcatheter aortic valve implantation (TAVI) procedures, the off-pump implantation of a valved stent into the mitral position mainly via a transapical approach will be of great benefit. Recently, the feasibility of transcatheter mitral valved stent implantation in high-risk patients has already been reported.

  12. Acute mitral regurgitation in Takotsubo cardiomyopathy.

    Bouabdallaoui, Nadia; Wang, Zhen; Lecomte, Milena; Ennezat, Pierre V; Blanchard, Didier


    Takotsubo cardiomyopathy (TTC) is a well-recognised entity that commonly manifests with chest pain, ST segment abnormalities and transient left ventricular apical ballooning without coronary artery obstructive disease. This syndrome usually portends a favourable outcome. In the rare haemodynamically unstable TTC patients, acute mitral regurgitation (MR) related to systolic anterior motion (SAM) of the mitral valve and left ventricular outflow tract obstruction (LVOTO) is to be considered. Bedside echocardiography is key in recognition of this latter condition as vasodilators, inotropic agents or intra-aortic balloon counter-pulsation worsen the patient's clinical status. We discuss here a case of TTC where nitrate-induced subaortic obstruction and mitral regurgitation led to haemodynamic instability.

  13. Safety and effectiveness of combined percutaneous coronary angioplasty and aortic valvuloplasty in an elderly patient with cardiogenic shock: effect on concomitant severe mitral regurgitation.

    Emanuele Cecchi


    Full Text Available An 80-year-old diabetic man with severe aortic stenosis was admitted to our hospital for cardiogenic shock complicating non-ST-elevation myocardial infarction. Echocardiographic evaluation showed also a severe degree of both left ventricular dysfunction and mitral regurgitation. The patient was initially stabilized with inotropes and mechanical ventilation was necessary because of concurrent pulmonary edema. The day after, he was submitted to coronary angiography showing bivessel coronary disease. Given the high estimated operative risk, the patient was treated with angioplasty and bare metal stent implantation on both right coronary and circumflex artery; contemporarily, balloon aortic valvuloplasty (BAV was performed with anterograde technique, obtaining a significant increase in planimetric valve area and reduction in transvalvular peak gradient. Few days after the procedure echocardiogram showed an increase in left ventricular ejection fraction, moderate aortic stenosis with mild regurgitation and moderate mitral regurgitation. Hemodynamic and clinical stabilization were also obtained, allowing amine support discontinuation and weaning from mechanical ventilation. At three months follow-up, the patient reported a further clinical improvement from discharge, and echocardiographic evaluation showed moderate aortic stenosis and an additional increase in left ventricular function and decrease in mitral regurgitation degree. In conclusion, combined BAV and coronary angioplasty were associated in our patient with hemodynamic and clinical stabilization as well as with a significant reduction in transvalvular aortic gradient and mitral regurgitation and an increase in left ventricular ejection fraction both in-hospital and at three month follow-up; this case suggests that these procedures are feasible even in hemodynamically unstable patients and are associated with a significant improvement in quality of life.

    Resection of the chordopapillary apparatus during mitral valve replacement has been associated with a negative impact on survival. Mitral valve replacement with the preservation of the mitral valve apparatus has been associated with better outcomes, but surgeons remain refractory to its use. To determine if there is any real difference in preservation vs non-preservation of mitral valve apparatus during mitral valve replacement in terms of outcomes, we performed a systematic review and meta-analysis using MEDLINE, EMBASE, CENTRAL/CCTR, SciELO, LILACS, Google Scholar and reference lists of relevant articles to search for clinical studies that compared outcomes (30-day mortality, postoperative low cardiac output syndrome or 5-year mortality) between preservation vs non-preservation during mitral valve replacement from 1966 to 2011. The principal summary measures were odds ratios (ORs) with 95% confidence interval and P-values (that will be considered statistically significant when mitral valve replacement preservation and 1917 for mitral valve replacement non-preservation). There was significant difference between mitral valve replacement preservation and mitral valve replacement non-preservation groups in the risk of 30-day mortality (OR 0.418, P mitral valve apparatus during mitral valve replacement.

  15. Straddling mitral valve with hypoplastic right ventricle, crisscross atrioventricular relations, double outlet right ventricle and dextrocardia: morphologic, diagnostic and surgical considerations.

    Geva, T; Van Praagh, S; Sanders, S P; Mayer, J E; Van Praagh, R


    The clinical, surgical and morphologic findings in five cases of a rare form of straddling mitral valve are presented. Three patients were diagnosed by two-dimensional echocardiography, cardiac catheterization and angiocardiography and two had diagnostic confirmation at autopsy. All five cases shared a distinctive and consistent combination of anomalies: 1) dextrocardia; 2) visceroatrial situs solitus, concordant ventricular D-loop and double outlet right ventricle with the aorta positioned to the left of and anterior to the pulmonary artery; 3) hypoplasia of right ventricular inflow (sinus) with tricuspid valve stenosis or hypoplasia; 4) large right ventricular infundibulum (outflow); 5) malalignment conoventricular septal defect; 6) straddling mitral valve with chordal attachments to the left ventricle and right ventricular infundibulum; 7) severe subpulmonary stenosis with well developed pulmonary arteries; and 8) superoinferior ventricles with crisscross atrioventricular (AV) relations. The degree of malalignment between the atrial and ventricular septa was studied quantitatively by measuring the AV septal angle projected on the frontal plane. The AV septal angle in the two postmortem cases was 150 degrees, reflecting marked malalignment of the ventricles relative to the atria. This AV malalignment appears to play an important role in the morphogenesis of straddling mitral valve. As judged by a companion study of seven postmortem cases, the more common form of straddling mitral valve with a hypertrophied and enlarged right ventricular sinus had less severe ventricular malposition than did the five rare study cases with hypoplastic right ventricular sinus. A competent mitral valve, low pulmonary vascular resistance and low left ventricular end-diastolic pressure were found at cardiac catheterization in the three living patients who underwent a modified Fontan procedure and are doing well 2.2 to 5.8 years postoperatively.

  16. The serpentine mitral valve and cerebral embolism

    Ker James


    Full Text Available Abstract Valvular strands, well-delineated filiform masses, attached to cardiac valve edges are associated with cerebral embolism and stroke. Strokes, caused by emboli from valvular strands, tend to occur among younger persons. In this case report a valvular strand, giving a peculiar serpentine appearance to the mitral valve is described. This mitral valvular strand was the only explanation for an episode of cerebral embolism, presenting with a transient right sided hemiparesis. It is proposed that a randomized study involving combined treatment with aspirin and clopidogrel is warranted in young patients with valvular strands, presenting with a first episode of cerebral embolism.

  20. Rheumatic heart disease in Tennessee: An overlooked diagnosis

    Shahana A Choudhury


    Full Text Available Rheumatic heart disease, already a major burden in low- and middle-income countries, is becoming an emerging problem in high-income countries. Although acute rheumatic fever and rheumatic heart disease have almost been eradicated in areas with established economies, the emergence of this problem may be attributable to the migration from low-income to high-income settings. Between 2010 and 2012, we diagnosed a cluster of rheumatic heart disease cases in children from the Middle Tennessee area. The goal of this report is to increase awareness among clinicians as the incidence and prevalence of acute rheumatic fever remain relatively significant in large US metropolitan areas. Although acute rheumatic fever is seasonal, a high suspicion index may lead to the early diagnosis and prevention of its cardiac complications. Furthermore, screening procedures may be recommended for populations at risk for rheumatic heart disease in endemic areas, and active surveillance with echocardiography-based screening might become very important.

  1. Mitral valve repair and redo repair for mitral regurgitation in a heart transplant recipient

    Bouma Wobbe


    Full Text Available Abstract A 37-year-old man with end-stage idiopathic dilated cardiomyopathy underwent an orthotopic heart transplant followed by a reoperation with mitral annuloplasty for severe mitral regurgitation. Shortly thereafter, he developed severe tricuspid regurgitation and severe recurrent mitral regurgitation due to annuloplasty ring dehiscence. The dehisced annuloplasty ring was refixated, followed by tricuspid annuloplasty through a right anterolateral thoracotomy. After four years of follow-up, there are no signs of recurrent mitral or tricupid regurgitation and the patient remains in NYHA class II. Pushing the envelope on conventional surgical procedures in marginal donor hearts (both before and after transplantation may not only improve the patient’s functional status and reduce the need for retransplantation, but it may ultimately alleviate the chronic shortage of donor hearts.

  2. Association of Triglyceride-Related Genetic Variants With Mitral Annular Calcification.

    Mitral annular calcium (MAC), commonly identified by cardiac imaging, is associated with cardiovascular events and predisposes to the development of clinically important mitral valve regurgitation and mitral valve stenosis. However, its biological determinants remain largely unknown. The authors sought to evaluate whether a genetic predisposition to elevations in plasma lipids is associated with the presence of MAC. The authors used 3 separate Mendelian randomization techniques to evaluate the associations of lipid genetic risk scores (GRS) with MAC in 3 large patient cohorts: the Framingham Health Study, MESA (Multiethnic European Study of Atherosclerosis), and the AGE-RS (Age, Gene/Environment Susceptibility-Reykjavik Study). The authors provided cross-ethnicity replication in the MESA Hispanic-American participants. MAC was present in 1,149 participants (20.4%). In pooled analyses across all 3 cohorts, a triglyceride GRS was significantly associated with the presence of MAC (odds ratio [OR] per triglyceride GRS unit: 1.73; 95% confidence interval [CI]: 1.24 to 2.41; p = 0.0013). Neither low- nor high-density lipoprotein cholesterol GRS was significantly associated with MAC. Results were consistent in cross-ethnicity analyses among the MESA Hispanic-Americans cohort (OR per triglyceride GRS unit: 2.04; 95% CI: 1.03 to 4.03; p = 0.04). In joint meta-analysis across all included cohorts, the triglyceride GRS was associated with MAC (OR per triglyceride GRS unit: 1.79; 95% CI: 1.32 to 2.41; p = 0.0001). The results were robust to several sensitivity analyses that limit both known and unknown forms of genetic pleiotropy. Genetic predisposition to elevated triglyceride levels was associated with the presence of MAC, a risk factor for clinically significant mitral valve disease, suggesting a causal association. Whether reducing triglyceride levels can lower the incidence of clinically significant mitral valve disease requires further study. Copyright © 2017

    Full Text Available Aim: To assess clinical and functional efficacy of implanted biological prosthesis “ASPIRE” (manufactured by Vascutek for correction of mitral valve disease.Materials and methods: From October 2008 to December 2013, biological prostheses “ASPIRE” (Vascutek were implanted to 34 patients with mitral valve disease (mean age 63.59 ± 4.96 years, 79.4% female. From these, 24 patients had mitral stenosis and 10 patients had mitral insufficiency. 73.5% of all patients had heart failure Strazhesko-Vasilenko IIA grade and 85.3% of patients had chronic heart failure NYHA III. Isolated mitral valve replacement was performed only in 8 (23.5% of patients. In 22 (64.7% of cases mitral valve replacement was combined with tricuspid valvuloplasty in various modifications. Duration of cardiopulmonary bypass and of aortic clamping was 88.09 ± 25.95 and 65.68 ± 25.51 minutes, respectively. Before and after surgery all patients underwent echocardiographic assessment and clinical assessment of their general status.Results: In-hospital mortality was 5.88% (n = 2 and was related to multiorgan failure in the early postoperative period. All 32 (94.12% surviving patients improved with decrease or complete disappearance of heart failure. Postoperative complications were typical for cardiac surgery. There were no episodes of embolism, structural dysfunction, thrombosis of the prosthesis and endocarditis of the prosthesis in the early postoperative period. Pressure gradients across prosthetic valves were not high and corresponded to good clinical and hemodynamic results in the early postoperative period.Conclusion: Taking into account good immediate results of mitral valve replacement, as well as no need in lifelong anticoagulation in patients with multiple concomitant disorders, implantation of the biological prosthesis “ASPIRE” (Vascutek could become a procedure of choice for correction of valve abnormalities in patients above 65 years.

  6. Percutaneous and minimally invasive approaches to mitral valve repair for severe mitral regurgitation-new devices and emerging outcomes

    Fadi E Shamoun


    Full Text Available Mitral valve disease is common in the United States and around the world, and if left untreated, increases cardiovascular morbidity and mortality. Mitral valve repair is technically more demanding than mitral valve replacement. Mitral valve repair should be considered the first line of treatment for mitral regurgitation in younger patients, mitral valve prolapse, annular dilatation, and with structural damage to the valve. Several minimally invasive percutaneous treatment options for mitral valve repair are available that are not restricted to conventional surgical approaches, and may be better received by patients. A useful classification system of these approaches proposed by Chiam and Ruiz is based on anatomic targets and device action upon the leaflets, annulus, chordae, and left ventricle. Future directions of minimally invasive techniques will include improving the safety profile through patient selection and risk stratification, improvement of current imaging and techniques, and multidisciplinary education.

  7. [Successful mitral valve replacement in a patient with functional mitral regurgitation induced by cardiac sarcoidosis;report of a case].

    Sato, Ken; Takazawa, Ippei; Aizawa, Kei; Misawa, Yoshio


    We report a case of cardiac sarcoidosis associated with mitral valve regurgitation. A 62-year-old woman with cardiac sarcoidosis was admitted for the treatment of an intractable mitral regurgitation. She had been treated for cardiac sarcoidosis with prednisolone, and she had undergone pacemaker implantation because of advanced complete A-V block 5 years before. However, her hemodynamics deteriorated, and echocardiography revealed severe functional mitral regurgitation, thinning of the ventricular septum, and left ventricular dysfunction. The patient underwent mitral valve replacement with a mechanical prosthetic valve, and her postoperative course was uneventful. She is currently well without exacerbation of heart failure at 2 years after operation. Functional mitral regurgitation is a relatively common complication in patients with cardiac sarcoidosis. Mitral valve replacement should be considered in patients with medically intractable mitral valve dysfunction due to cardiac sarcoidosis.

  11. Double mitral valve orifice. Two-dimensional and Doppler echocardiographic diagnosis.

    Solorio, S; Badui, E; Yáñez, M; Enciso, R; Rodríguez, L; Quintero, L R


    The purpose of this study was to demonstrate the usefulness of two-dimensional and Doppler echocardiography for diagnosing double mitral valve orifices (DMVO) in addition to identifying associated pathologies. We report five cases, three male and two female with an age ranging from 4 to 44 years old (mean age: 17 years), with the diagnosis of DMVO according to the following characteristics: using two-dimensional echocardiography on the short parasternal axis, both orifices were observed; apical in which the "seagull sign" was identified in both chambers, in addition to identifying the flows of each orifice by pulsed and codified color Doppler obtaining the corresponding gradients. With respect to the associated pathologies, all patients presented some type of malformation, such as subaortic ring, patent ductus arteriosus, coarctation of the aorta, bicuspid aorta and pulmonary stenosis. Using the color Doppler echocardiography allows an adequate anatomical and functional definition of DMVO.

  12. [Subglottic stenosis and gastroesophageal reflux].

    Fligny, I; François, M; Aigrain, Y; Polonovski, J M; Contencin, P; Narcy, P


    The authors report the cases of ten children treated for sub-glottic laryngeal stenosis, in the Department of Pr. Narcy in Hospital Robert-Debre. Medical treatment of the laryngeal stenosis had failed in these cases. Treatment, most often surgical, of the gastro-oesophageal reflux present in these ten cases enabled these children to be cured. A review of the literature stresses the role and responsibility of gastro-oesophageal reflux in laryngeal pathology. Based on their experience, the authors suggest: systematic investigation for gastro-oesophageal reflux during management of laryngeal stenosis, especially when laryngeal inflammation is encountered; the adoption of an interventionist attitude vis-a-vis gastro-oesophageal reflux which would seem to have an important pathogenic role in certain laryngeal stenoses.

  13. Robotic trans-atrial and trans-mitral ventricular septal resection


    Localized ventricular septal hypertrophy, also known as idiopathic hypertrophic subaortic stenosis or idiopathic hypertrophic subaortic septal obstruction (IHSS), can create severe ventricular outflow obstruction. This often results in a high sub-aortic pressure gradient with potentially lethal symptoms. In 1960, Braunwald described the hemodynamic characteristics of IHSS, and thereafter, Morrow developed a trans-aortic approach to resect a large part of the ventricular septum, enlarging the outflow tract. The Morrow operation has remained the gold standard for surgically treating this pathology. However, in patients with a small aortic annulus, a severely hypertrophied septum, and a long anterior mitral leaflet, the trans-aortic approach may be more difficult, resulting in an inadequate resection and/or systolic anterior leaflet motion. The latter usually increases the obstruction and can cause mitral regurgitation. Herein, we describe a minimally invasive trans-left atrial robotic approach to treat IHSS. First, the anterior mitral leaflet is incised radially to reveal the aortic outflow tract and ventricular septum, which are located posteriorly. Thereafter, a deep “block” of septum is excised, beginning at the right valve cusp nadir and continued counterclockwise toward the left fibrous trigone. This excision is extended to the anterior papillary muscle base, where any septal connections must be divided. Subsequently, the anterior leaflet is re-suspended and the repair is completed with a flexible annuloplasty band. If necessary, the anterior leaflet can be augmented with a pericardial patch. The “wristed” robotic instruments and magnified 3-D vision definitely facilitate an adequate septal resection and anterior papillary muscle mobilization. Moreover, it is possible that this fine control helps to reduce complications, such as heart block or a ventricular septal defect. PMID:28203542

  15. The management of rheumatic diseases in pregnancy.

    Mitchell, K; Kaul, M; Clowse, Megan E B


    Pregnancy can create a challenge for physicians caring for women with rheumatic diseases. For many women with rheumatoid arthritis (RA), pregnancy can provide a reprieve from long-term joint pain and inflammation, but others will not experience remission and will continue to need medication. Systemic lupus erythematosus (SLE) may remain quiet in some women, but in others may become more aggressive during pregnancy, putting both mother and foetus at risk. Women with limited scleroderma can do remarkably well, but scleroderma renal crises can be difficult to manage. A third of pregnancies in women with antiphospholipid syndrome (APS) may be refractory to our best therapy. In general, active inflammation from rheumatic diseases poses a stronger threat to the well-being of both mother and foetus than many immunosuppressant medications. Therefore, continued immunosuppression with the least risky medications will allow for the most optimal pregnancy outcomes.

  16. [The rheumatism of acne conglobata (author's transl)].

    Bastin, R; Verliac, F; Kernbaum, S; Kahn, M F; Feffer, J; Habas, J P


    The authors report a case of painful joint, para-articular and muscular involvement accompanying acne conglobata. Fifteen other cases of rheumatism associated with this very special type of acne have been reported. The patients affected are young men suffering from acne conglobata (severe form of acne characterised by its ulcerating course and the possibility of its being accompanied by systemic manifestations), who suddenly develop fever, an altered general state and assymetrical arthralgia involving mainly the large joints, accompanied by signs of muscular involvement. The course is one of spontaneous recovery, relapses being possible. This falls within the context of the group of rheumatic disorders associated with the signs of an inflammatory skin disease.

  17. Management of rheumatic chorea: an observational study

    Araújo Alexandra Prufer de Queiroz Campos


    Full Text Available BACKGROUND: Rheumatic chorea (RC has recently been linked to an antibody-mediated immune mechanism. OBJECTIVE/METHOD: To verify if this knowledge reflected in management changes we conceived a descriptive study. RESULTS: The medical charts of 20 children (13 females aged 6 to 12 years (mean 8 years, diagnosed as RC from June 1996 to June 1999, were reviewed. All patients received some medical treatment. Haloperidol was the most prescribed medication (15 patients - 75 %. Sulpiride, diazepam and valproate were also used as symptomatic treatment. Imune-modulating therapy with prednisone was prescribed for seven children. The shortest course of chorea (16 days occurred in a patient treated with prednisone. CONCLUSION: Prednisone has been prescribed for rheumatic chorea besides the traditional symptomatic approach. A great variety of antichoreic drugs are being employed.

  18. Autoimmune neuropathies associated to rheumatic diseases.

    Martinez, Alberto R M; Faber, Ingrid; Nucci, Anamarli; Appenzeller, Simone; França, Marcondes C


    Systemic manifestations are frequent in autoimmune rheumatic diseases and include peripheral nervous system damage. Neuron cell body, axons and myelin sheath may all be affected in this context. This involvement results in severe and sometimes disabling symptoms. Sensory, motor and autonomic features may be present in different patterns that emerge as peculiar clinical pictures. Prompt recognition of these neuropathies is pivotal to guide treatment and reduce the risks of long term disability. In this review, we aim to describe the main immune-mediated neuropathies associated to rheumatic diseases: sensory neuronopathies, multiple mononeuropathies and chronic inflammatory demyelinating polyradiculoneuropathy, with an emphasis on clinical features and therapeutic options.

  19. Ultrasound of enthesopathy in rheumatic diseases.

    Falsetti, Paolo; Acciai, Caterina; Lenzi, Lucia; Frediani, Bruno


    Enthesopathy is the pathologic change of the insertion of tendons, ligaments and joint capsules on the bone. It is a cardinal feature of spondyloarthropathies (SpA), but it can occur in other rheumatic disease. Recent studies using magnetic resonance imaging (MRI) and ultrasonography (US) have demonstrated that enthesopathy can often be asymptomatic, in both the axial and peripheral skeleton. Therefore, a systematic US study of peripheral entheses could be useful in the diagnostic process of patients with rheumatic diseases, in particular SpA. Recently, power Doppler US (PDUS) has been proved to be useful for differentiating mechanical/degenerative and inflammatory enthesopathy and for monitoring the efficacy of therapy. This article reviews the main histopathologic aspects of enthesopathy and describes the normal US features of enthesis and the basic US features of enthesopathy, in its various stages. The usefulness of US and PDUS in the diagnosis and assessment of enthesopathy is discussed on the basis of the literature and our experience.

  20. Mast Cells Might Have a Protective Role against the Development of Calcification and Hyalinisation in Severe Aortic Valve Stenosis.

    Milutinovic, A; Petrovič, D; Zorc, M; Vraspir Porenta, O; Arko, M; Pleskovič, A; Alibegovic, A; Zorc-Pleskovic, R


    Aortic valve stenosis is characterized by inflammation and extracellular matrix remodelling. The aim of this study was to analyse the impact of mast cells on the occurrence of histopathological changes of aortic valves in patients with severe grade, non-rheumatic degenerative aortic valve stenosis. Valve specimens were obtained from 38 patients undergoing valve replacement. The role of mast cells was analysed by dividing the specimens into two groups, characterized by the presence (group A, N = 13) or absence of mast cells (group B, N = 25). There were no significant differences in clinical data between the two groups. In group A, T cells and macrophages were present in all aortic valves, as compared to a significantly lower proportion of valves with T cells and macrophages in group B. Valves in group A were less often calcified and hyaline-degenerated than valves in group B. There were no changes in fibrosis between the two groups. We found a positive correlation between the presence of mast cells and macrophages/T cells, a negative correlation between the presence of mast cells and calcification/ hyaline degeneration, and no correlation between the presence of mast cells and fibrosis. There was also a negative correlation between the presence of macrophages/T cells and calcification. The linear regression model identified only the presence of mast cells as an independent negative prediction value for calcification. In conclusion, mast cells might have a protective role against the development of calcification and hyaline degeneration in severe grade, non-rheumatic aortic valve stenosis.

  4. Role of diet in rheumatic disease.

    Li, Sophia; Micheletti, Robert


    Millions of people suffer from rheumatic diseases such as gout, fibromyalgia, osteoarthritis, and rheumatoid arthritis. These can be incapacitating and detrimental to quality of life. Diet, nutrition, and weight loss have shown promise in alleviating some of this disease burden. These lifestyle changes may give patients a feeling of control and ownership over their disease as well as a nonpharmacologic means of treatment. This article reviews the available research on the effects of diet and nutrition on rheumatoid disease.

  5. Technical aspects of mitral valve replacement with an allograft for acute bacterial endocarditis.

    Conklin, L D; Reardon, M J


    Mitral valve replacement with a mitral valve allograft is receiving a resurgence of interest. We discuss the technical aspects of this procedure as it applies to cases of acute bacterial endocarditis infecting the mitral valve.

  6. [Bloodletting and rheumatism.: a retrospective view].

    Kaiser, H


    Bloodletting was widely used in antiquity in the setting of a humoral-pathological concept as a general treatment for all ailments, as well as during the middle ages primarily as a remedy for the treatment of inflammatory and infectious diseases. The general population was convinced of the efficacy of this treatment for centuries, even requesting it on occasion on a prophylactic basis. Although questioned early in history, the number of sceptical voices increased in the 17th and 18th centuries. In 1835, P. Louis introduced statistics to medicine in Paris, thereby proving the inefficacy of bloodletting in inflammatory diseases. Today, bloodletting is used in scientific medicine in only a few rare disease.As long as rheumatic diseases remained undifferentiated, all cases were treated with bloodletting. After acute articular rheumatism 1591 was recognised as an independent disease entity, bloodletting remained the treatment of choice for most doctors right up to the end of the 19th century. Bloodletting was also the standard treatment for gout from antiquity up to the beginning of the 19th century. Following its differentiation in 1800, chronic articular rheumatism was no longer treated with venae sectio. Today, there is no indication for bloodletting therapy in rheumatology.

  7. Adipokines, metabolic syndrome and rheumatic diseases.

    Abella, Vanessa; Scotece, Morena; Conde, Javier; López, Verónica; Lazzaro, Verónica; Pino, Jesús; Gómez-Reino, Juan J; Gualillo, Oreste


    The metabolic syndrome (MetS) is a cluster of cardiometabolic disorders that result from the increasing prevalence of obesity. The major components of MetS include insulin resistance, central obesity, dyslipidemia, and hypertension. MetS identifies the central obesity with increased risk for cardiovascular diseases (CVDs) and type-2 diabetes mellitus (T2DM). Patients with rheumatic diseases, such as rheumatoid arthritis, osteoarthritis, systemic lupus erythematosus, and ankylosing spondylitis, have increased prevalence of CVDs. Moreover, CVD risk is increased when obesity is present in these patients. However, traditional cardiovascular risk factors do not completely explain the enhanced cardiovascular risk in this population. Thus, MetS and the altered secretion patterns of proinflammatory adipokines present in obesity could be the link between CVDs and rheumatic diseases. Furthermore, adipokines have been linked to the pathogenesis of MetS and its comorbidities through their effects on vascular function and inflammation. In the present paper, we review recent evidence of the role played by adipokines in the modulation of MetS in the general population, and in patients with rheumatic diseases.

  9. Soft-tissue rheumatism: diagnosis and treatment.

    Reveille, J D


    Soft tissue rheumatism is one of the most common and most misunderstood categories of disorders facing the primary care physician. Among the more common types are subacromial bursitis, epicondylitis, trochanteric bursitis, anserine bursitis, and fibromyalgia. The keys to the diagnosis of soft-tissue rheumatism are the history and, more importantly, the physical examination. Extensive laboratory testing and radiographs are not as helpful in evaluating patients with these complaints. Treatment consists of nonsteroidal anti-inflammatory drugs (NSAIDs) and nonnarcotic analgesics. Especially in patients with localized disorders, intralesional injections of corticosteroids are particularly effective and safe and should be part of the armamentarium of the primary care practitioner. Fibromyalgia is a particularly challenging form of nonarticular rheumatism. The clinical presentation is rather characteristic, with the patient typically being a woman 30-60 years of age who presents with diffuse somatic pain. Patients often give a history of sleep disturbance, may be depressed, and show characteristic tender areas, or trigger points. Laboratory findings are normal. Management includes reassurance, correction of the underlying sleep disturbance with low doses of a tricyclic antidepressant, treatment with muscle relaxants and nonnarcotic analgesics or NSAIDs, and an exercise program with a strong aerobic component.

  10. Iterative Learning of Transcatheter Mitral Valve Replacement in Mitral Valve Annulus Calcification: Management and Prevention of Transcatheter Mitral Valve Replacement Dislocation.

    Hulman, Michal; Bena, Martin; Artemiou, Panagiotis; Gasparovic, Ivo; Hudec, Vladan; Rajani, Ronak; Bapat, Vinayak


    Transcatheter mitral valve replacement using balloon-expandable valves is an emerging technique for the treatment of patients with significant mitral regurgitation who have been judged to be inoperable owing to significant mitral valve annulus calcification. Although initial reports have been promising, there remains a lack of consensus as to how to plan for transcatheter mitral valve replacement deployment in terms of appropriateness, sizing, and positioning to mitigate the risks of valve displacement and paravalvular regurgitation. We describe two cases of transcatheter mitral valve replacement in patients with significant mitral valve annulus calcification. The first was complicated by valve displacement into the left atrium, which was successfully managed by surgical redeployment and fixation. The second case was thereafter performed successfully using iterative learning and the application of specific preprocedural planning techniques acquired from a root cause analysis of the first case. We describe our experience with both cases and the specific planning principles required to prevent transcatheter mitral valve replacement displacement in patients with mitral valve annulus calcification.

  11. Dynamic change in mitral annular area and motion during percutaneous mitral annuloplasty for ischemic mitral regurgitation: preliminary animal study with real-time 3-dimensional echocardiography.

    Daimon, Masao; Gillinov, A Marc; Liddicoat, John R; Saracino, Giuseppe; Fukuda, Shota; Koyama, Yasushi; Hayase, Motoya; Cohn, William E; Ellis, Stephen G; Thomas, James D; Shiota, Takahiro


    We used a novel 3-dimensional (3D) echocardiographic technique to evaluate the impact of a coronary sinus-based percutaneous transvenous mitral annuloplasty (PTMA) on dynamic changes in mitral annular geometry and motion during the cardiac cycle in 8 sheep with ischemic mitral regurgitation. Using real-time 3D echocardiographic data before and after PTMA, 10 points along the saddle-shaped annulus were identified. For every 3D volume/frame during a cardiac cycle, we assessed mitral annular area and excursion defined as the traveling distance of the annular center. The PTMA device reduced both minimum and maximal mitral annular area (9.5 +/- 0.9-7.0 +/- 0.6 and 12.8 +/- 1.3-9.8 +/- 1.5 cm(2), P < .001 for both, respectively) with reduction of mitral regurgitation jet area (5.1 +/- 2.3-1.2 +/- 0.8 cm(2), P < .001), whereas it did not significantly impair mitral annular excursion amplitude (8.3 +/- 1.1-7.0 +/- 1.9 mm, P = .13). This 3D echocardiographic method noninvasively enabled dynamic study of mitral annular geometry and motion with quantitative analysis of the impact of PTMA.

  13. Acute severe mitral regurgitation: consideration of papillary muscle architecture

    Pascoe Edward


    Full Text Available Abstract We present a case of an individual who presented with acute severe mitral regurgitation in the setting of an inferior ST elevation myocardial infarction. Both transthoracic and transesophageal echocardiography demonstrated a posteriorly directed eccentric jet of severe mitral regurgitation with flail anterior mitral valve leaflet attached presumably to the anterior papillary muscle. Intraoperative findings demonstrated rupture of the postero-medial papillary muscle attached via chords to the anterior mitral valve leaflet. This case serves to remind us that both the anterior and posterior leaflets of the mitral valve are attached to both papillary muscle heads. The direction and eccentricity of the mitral regurgitant jet on echocardiography helps to locate the leaflet involved, but not necessarily the coexisting papillary muscle pathology.

  15. Ekhokardiografi Endokardiosis Penyakit Katup Mitral Jantung Anjing (ECHOCARDIOGRAPHY OF ENDOCARDIOSIS MITRAL VALVE HEART DISEASE IN DOGS

    Deni Noviana


    Full Text Available Endocardiosis is a disease commonly found in Pomeranian dog characterized by progressive myxomatousdegeneration of the atrio-ventricular valves especially in the mitral valve. The purpose of this study was todefine the diagnose and severeity of this disease on the Pomeranian by using brightness mode, motion mode,dan color flow Doppler echocardiography technique. Echocardiography was performed on 8 Pomeranianconsisting of 6 males and 2 females with age range of 2-14 years. Brightness mode echocardiography wasused to see the echotexture of endocardium, mitral valve, and the valve movement. The results showedendocardium thickening, along with chronic fibrosis and nodular thickening of the anterior and posteriormitral valve leaflet. Three out of seven cases showed prolapsed of the mitral valve. Motion modeechocardiography was performed in order to measure left ventricle internal dimension, myocardium thickness,fractional shortening, left atrial and aortic dimension. The results showed myocardium thickening, alongwith left atrial enlargement. Color flow Doppler echocardiography was used to confirm the mitral valveregurgitation. Three of seven cases showed the presence of regurgitation signed by turbulence color of theprolapsed mitral valve. Based on the degree of severity, scoring system used in this study, endocardiosis canbe divided into three types that are mild, moderate and severe.

    Introduction: The commonest mitral regurgitation etiologies are degenerative (60%), rheumatic post-inflammatory, 12%) and functional (25%). Due to the large number of patients with acute MI, the incidence of ischaemic MR is also high. Ischaemic mitral regurgitation is a complex multifactorial disease that involves left ventricular geometry, the mitral annulus, and the valvular/subvalvular apparatus. Ischaemic mitral regurgitation is an important consequence of LV remodeling after myocardial infarction. Research Objectives: The objective of this study is to determine the role of echocardiography in detecting and assessment of mitral regurgitation mechanism, severity, impact on treatment strategy and long term outcome in patients with myocardial infarction during the follow up period of 5 years. Also one of objectives to determine if the absence or presence of ischaemic MR is associated with increased morbidity and mortality in patients with myocardial infarction. Patients and methods: The study covered 138 adult patients. All patients were subjected to echocardiography evaluation after acute myocardial infarction during the period of follow up for 5 years. The patients were examined on an ultrasound machine Philips iE 33 xMatrix, Philips HD 11 XE, and GE Vivid 7 equipped with all cardiologic probes for adults and multi-plan TEE probes. We evaluated mechanisms and severity of mitral regurgitation which includes the regurgitant volume (RV), effective regurgitant orifice area (EROA), the regurgitant fraction (RF), Jet/LA area, also we measured the of vena contracta width (VC width cm) for assessment of IMR severity, papillary muscles anatomy and displacement, LV systolic function ± dilation, LV regional wall motion abnormality WMA, LV WMI, Left ventricle LV remodeling, impact on treatment strategy and long term mortality. Results: We analyzed and follow up 138 patients with previous (>16 days) Q-wave myocardial infarction by ECG who underwent TTE and TEE

  17. En face view of the mitral valve: definition and acquisition.

    Mahmood, Feroze; Warraich, Haider Javed; Shahul, Sajid; Qazi, Aisha; Swaminathan, Madhav; Mackensen, G Burkhard; Panzica, Peter; Maslow, Andrew


    A 3-dimensional echocardiographic view of the mitral valve, called the "en face" or "surgical view," presents a view of the mitral valve similar to that seen by the surgeon from a left atrial perspective. Although the anatomical landmarks of this view are well defined, no comprehensive echocardiographic definition has been presented. After reviewing the literature, we provide a definition of the left atrial and left ventricular en face views of the mitral valve. Techniques used to acquire this view are also discussed.

  18. Finite element analysis to model complex mitral valve repair.

    Labrosse, Michel; Mesana, Thierry; Baxter, Ian; Chan, Vincent


    Although finite element analysis has been used to model simple mitral repair, it has not been used to model complex repair. A virtual mitral valve model was successful in simulating normal and abnormal valve function. Models were then developed to simulate an edge-to-edge repair and repair employing quadrangular resection. Stress contour plots demonstrated increased stresses along the mitral annulus, corresponding to the annuloplasty. The role of finite element analysis in guiding clinical practice remains undetermined.

  19. Acute aortic and mitral valve regurgitation following blunt chest trauma.

    Bernabeu, Eduardo; Mestres, Carlos A; Loma-Osorio, Pablo; Josa, Miguel


    Traumatic rupture of intracardiac structures is an uncommon phenomenon although there are a number of reports with regards to rupture of the tricuspid, mitral and aortic valves. We report the case of a 25-year-old patient who presented with acute aortic and mitral valve regurgitation of traumatic origin. Both lesions were seen separated by 2 weeks. Pathophysiology is reviewed. The combination of both aortic and mitral lesions following blunt chest trauma is almost exceptional.

    Significant mitral regurgitation (MR) is frequent in patients with severe aortic stenosis (AS). In these cases, concomitant mitral valve repair or replacement is usually performed at the time of surgical aortic valve replacement (SAVR). Transcatheter aortic valve replacement (TAVR) has recently been considered as an alternative for patients at high or prohibitive surgical risk. However, concomitant significant MR in this setting is typically left untreated. Moderate to severe MR after aortic valve replacement is therefore a relevant entity in the TAVR era. The purpose of this review is to present the current knowledge on the clinical impact and post-procedural evolution of concomitant significant MR in patients with severe AS who have undergone aortic valve replacement (SAVR and TAVR). This information could contribute to improving both the clinical decision-making process in and management of this challenging group of patients.

  1. Pulmonary hypertension in autoimmune rheumatic diseases

    L. Massironi


    Full Text Available Objective. Pulmonary hypertension is a severe and rapidly progressive disease, particularly frequent in patients with rheumatic diseases. The aims of this study were the following: to determine the prevalence of pulmonary hypertension in Italian patients with autoimmune rheumatic diseases, and to evaluate if the presence of a rheumatic disease in general, or of a specific autoimmune rheumatic disease, is a risk factor for the development of pulmonary hypertension. Patients and Methods. One hundred and thirteen Italian patients with connective tissue diseases (105 females, 8 males, aged 19 to 83 yrs, entered the study. Fifty-one had systemic sclerosis (SSc: 49 were females, 2 males, aged 34 to 83 yrs; 41 had limited cutaneous SSc, 8 diffuse cutaneous SSc, and 2 SSc sine scleroderma. Thirty-three patients had systemic lupus erythematosus (SLE: all but one were females, their age ranged from 19 to 82 yrs. Twenty-five had rheumatoid arthritis (RA: 21 females, 4 males, aged 26 to 45 yrs. Three females and one male, 51-77 yrs, had mixed connective tissue disease (MCTD. Systolic pulmonary arterial pressure (SPAP was assessed by Doppler echocardiography. Results. Twenty three patients had pulmonary hypertension, which was more frequent in MCTD than in SLE (75% vs 6.1%, p=0.0002 or in AR (20%, p=0.0313. Pulmonary hypertension was more frequent in SSc than in SLE (25.5% vs 6.1%, p=0.0028 and in limited than in diffuse SSc(21.6% vs 3.9%. SPAP was significanly related to age (R=0.35, P=0.0275, with patients with pulmonary hypertension older than patients with normal SPAP (66±13 vs 52±16 yrs, p=0.0003. Conclusions. These data show a significant association between pulmonary hypertension and autoimmune rheumatic diseases. Therefore pulmonary hypertension assessment seems mandatory, at least in MCTD and SSc. However, more studies are needed to clarify the relationship between age and pulmonary hypertension and to verify whether the low prevalence of

  4. Mitral-aortic annular enlargement: modification of Manouguian's technique

    Costa Mario Gesteira


    Full Text Available We hereby present a technical modification for mitral-aortic annular enlargement. The mitral valve is replaced through the retro-septal approach, avoiding patches for left atrial roof closure. We report a mitral-aortic valve replacement in a patient whose original annuli would preclude adequate prostheses. The simultaneous annular enlargement may be necessary for avoiding patient-prosthesis mismatch and for reconstructing destroyed mitral and aortic annuli. The technique may minimize the risk of bleeding and of paravalvular leakage, using an approach well known to cardiac surgeons.

  5. Is primary prevention of rheumatic fever the missing link in the control of rheumatic heart disease in Africa?

    Karthikeyan, Ganesan; Mayosi, Bongani M


    Rheumatic fever and rheumatic heart disease continue to be major public health problems in the developing world, particularly in the countries of sub-Saharan Africa. Because of its cost effectiveness, secondary prophylaxis is advocated as the principal means of disease prevention and control. However, in developing countries, valvular damage, due to earlier, unrecognized episodes of rheumatic fever, has already occurred by the time secondary prophylaxis is instituted. Secondary prophylaxis cannot reduce the incidence of new cases of rheumatic fever and has not been shown to alter the natural history of rheumatic valvular disease. Experience from several regions of the world suggests that incorporation of a strategy of primary antibiotic prophylaxis into a comprehensive program for disease control can reduce the incidence of rheumatic fever and rheumatic heart disease. In this article, we argue that a strategy of primary antibiotic prophylaxis, with appropriate modifications, can be successfully implemented in resource-poor settings across the world and should be a key component of any rheumatic heart disease control program. This, we believe, is essential for reducing the global burden of rheumatic heart disease.

  6. Preservation versus non-preservation of mitral valve apparatus during mitral valve replacement: a meta-analysis of 3835 patients

    Sá, Michel Pompeu Barros de Oliveira; Ferraz, Paulo Ernando; Escobar, Rodrigo Renda; Martins, Wendell Santos; de Araújo e Sá, Frederico Browne Correia; Lustosa, Pablo César; Vasconcelos, Frederico Pires; Lima, Ricardo Carvalho


    Resection of the chordopapillary apparatus during mitral valve replacement has been associated with a negative impact on survival. Mitral valve replacement with the preservation of the mitral valve apparatus has been associated with better outcomes, but surgeons remain refractory to its use. To determine if there is any real difference in preservation vs non-preservation of mitral valve apparatus during mitral valve replacement in terms of outcomes, we performed a systematic review and meta-analysis using MEDLINE, EMBASE, CENTRAL/CCTR, SciELO, LILACS, Google Scholar and reference lists of relevant articles to search for clinical studies that compared outcomes (30-day mortality, postoperative low cardiac output syndrome or 5-year mortality) between preservation vs non-preservation during mitral valve replacement from 1966 to 2011. The principal summary measures were odds ratios (ORs) with 95% confidence interval and P-values (that will be considered statistically significant when <0.05). The ORs were combined across studies using a weighted DerSimonian–Laird random-effects model. The meta-analysis was completed using the software Comprehensive Meta-Analysis version 2 (Biostat Inc., Englewood, NJ, USA). Twenty studies (3 randomized and 17 non-randomized) were identified and included a total of 3835 patients (1918 for mitral valve replacement preservation and 1917 for mitral valve replacement non-preservation). There was significant difference between mitral valve replacement preservation and mitral valve replacement non-preservation groups in the risk of 30-day mortality (OR 0.418, P <0.001), postoperative low cardiac output syndrome (OR 0.299, P <0.001) or 5-year mortality (OR 0.380, P <0.001). No publication bias or important heterogeneity of effects on any outcome was observed. In conclusion, we found evidence that argues in favour of the preservation of mitral valve apparatus during mitral valve replacement. PMID:23027596

  7. Intraoperative evaluation of transmitral pressure gradients after edge-to-edge mitral valve repair.

    Jan N Hilberath

    Full Text Available OBJECTIVE: Edge-to-edge repair of the mitral valve (MV has been described as a viable option used for the surgical management of mitral regurgitation (MR. Based on the significant changes in MV geometry associated with this technique, we hypothesized that edge-to-edge MV repairs are associated with higher intraoperative transmitral pressure gradients (TMPG compared to conventional methods. METHODS: Patient records and intraoperative transesophageal echocardiography (TEE examinations of 552 consecutive patients undergoing MV repair at a single institution over a three year period were assessed. After separation from cardiopulmonary bypass (CPB, peak and mean TMPG were recorded for each patient and subsequently analyzed. RESULTS: 84 patients (15% underwent edge-to-edge MV repair. Peak and mean TMPG were significantly higher compared to gradients in patients undergoing conventional repairs: 10.7 ± 0.5 mmHg vs 7.1 ± 0.2 mmHg; P<0.0001 and 4.3 ± 0.2 mmHg vs 2.8 ± 0.1 mmHg; P<0.0001. Only patients with mean TMPG ≥ 7 mmHg (n = 9 required prompt reoperation for iatrogenic mitral stenosis (MS. No differences in peak and mean TMPG were observed among edge-to-edge repairs performed in isolation, compared to those performed in combination with annuloplasty: 11.0 ± 0.7 mmHg vs 10.3 ± 0.6 mmHg and 4.4 ± 0.3 mmHg vs 4.3 ± 0.3 mmHg. There were no differences in TMPG between various types of annuloplasty techniques used in combination with the edge-to-edge repairs. CONCLUSIONS: Edge-to-edge MV repairs are associated with higher intraoperative peak and mean TMPG after separation from CPB compared to conventional repair techniques. Unless gradients are severely elevated, these findings are not necessarily suggestive of iatrogenic MS. Thus, in the immediate postoperative period mildly elevated TMPG can be expected and tolerated after edge-to-edge mitral repairs.

  8. Impact of failed mitral valve repair on hospital outcome of redo mitral valve procedures.

    The prognostic impact of failed mitral valve repair (FMR) on in-hospital outcome after redo mitral valve surgery has not been thoroughly investigated. Hospital outcomes after redo mitral valve surgery because of an FMR in patients from nine European centres were reported. Logistic regressions identified predictors of mortality in combined or isolated redo mitral valve operations. Hospital outcome was compared between propensity-matched cohorts with FMR and native mitral valves in the context of redo surgery and FMR versus failed prostheses. A total of 246 patients with FMR yielded a 6.5% mortality rate at redo surgery. FMR per se did not impact mortality at multivariable analysis ( P = 0.64). A preoperative Global Initiative for Chronic Obstructive Lung Disease (GOLD) score ≥2 chronic obstructive lung disease (COPD) (OR 15.2, P FMR population. GOLD ≥ 2 COPD (OR 12.3, P = 0.049), age at surgery (OR 1.15 for each incremental year, P = 0.049) and cardiopulmonary bypass duration (OR 1.02, P = 0.022) predicted mortality in isolated redo mitral valve surgery for FMR. The fourth (> 68 years = 13.8% mortality) and the fifth quintiles of age (≥73.4 years = 14.8%) reported the highest mortality (OR 3.8 and 4.2 respectively, P = 0.002) in this subgroup. Propensity-matched cohorts of FMR and native mitral valves in the context of redo surgery showed no differences in terms of mortality ( P = 0.69) and major morbidity (acute myocardial infarction P = 0.31, stroke P = 0.65, acute kidney injury P  = 1.0), whereas more perioperative dialysis ( P = 0.04) and transfusions ( P = 0.02) were noted in propensity-matched failed prostheses compared to FMR. A failed mitral repair does not impact hospital outcome of redo surgery. Given the role of severe left ventricular dysfunction and advanced age on hospital mortality rates, an early indication for redo surgery may improve outcome.

  9. [A case of death due to mitral regurgitation caused by traumatic mitral valve injury].

    Iwasaki, Y; Kojima, T; Yasui, W; Nagasawa, N; Yashiki, M


    A 51-year-old male, who had been driving a motor bicycle, was involved in a traffic accident with a trailer, and he died immediately after the accident. According to the external examination of the victim, no fatal injuries were found. The medico-legal autopsy revealed a rupture of the left side of the pericardium, and a tear of the posterior leaflet of the mitral valve. There were no injuries of the papillary muscles and chordae. The cause of death was due to traumatic mitral regurgitation.

  10. Impact of mitral valve geometry on hemodynamic efficacy of surgical repair in secondary mitral regurgitation.

    Padala, Muralidhar; Gyoneva, Lazarina I; Thourani, Vinod H; Yoganathan, Ajit P


    Mitral valve geometry is significantly altered secondary to left ventricular remodeling in non-ischemic and ischemic dilated cardiomyopathies. Since the extent of remodeling and asymmetry of dilatation of the ventricle differ significantly between individual patients, the valve geometry and tethering also differ. The study aim was to determine if mitral valve geometry has an impact on the efficacy of surgical repairs to eliminate regurgitation and restore valve closure in a validated experimental model. Porcine mitral valves (n = 8) were studied in a pulsatile heart simulator, in which the mitral valve geometry can be precisely altered and controlled throughout the experiment. Baseline hemodynamics for each valve were measured (Control), and the valves were tethered in two distinct ways: annular dilatation with 7 mm apical papillary muscle (PM) displacement (Tether 1, symmetric), and annular dilatation with 7 mm apical, 7 mm posterior and 7 mm lateral PM displacement (Tether 2, asymmetric). Mitral annuloplasty was performed on each valve (Annular Repair), succeeded by anterior leaflet secondary chordal cutting (Sub-annular Repair). The efficacy of each repair in the setting of a given valve geometry was quantified by measuring the changes in mitral regurgitation (MR), leaflet coaptation length, tethering height and area. At baseline, none of the valves was regurgitant. Significant leaflet tethering was measured in Tether 2 over Tether 1, but both groups were significantly higher compared to baseline (60.9 +/- 31 mm2 for Control versus 129.7 +/- 28.4 mm2 for Tether 1 versus 186.4 +/- 36.3 mm2 for Tether 2). Consequently, the MR fraction was higher in Tether 2 group (23.0 +/- 5.7%) than in Tether 1 (10.5 +/- 5.5%). Mitral annuloplasty reduced MR in both groups, but remnant regurgitation after the repair was higher in Tether 2. After chordal cutting a similar trend was observed with trace regurgitation in Tether 1 group at 3.6 +/- 2.8%, in comparison to 18.6 +/- 4

  13. The Viable Mitral Annular Dynamics and Left Ventricular Function after Mitral Valve Repair by Biological Rings

    Farideh Roshanali


    Full Text Available Objective: Considering the importance of annular dynamics in the valvular and ventricular function, we sought to evaluate the effects of treated pericardial annuloplasty rings on mitral annular dynamics and left-ventricular (LV function after mitral valve repair. The results were compared with the mitral annular dynamics and LV function in patients with rigid and flexible rings and also in those without any heart problems. Materials and Methods: One hundred and thirty-six consecutive patients with a myxomatous mitral valve and severe regurgitation were prospectively enrolled in this observational cohort study. The patients underwent comparable surgical mitral valve reconstruction; of these 100 received autologous pericardium rings (Group I, 20 were given flexible prosthetic rings (Group II, and 16 received rigid rings (Group III. Other repair modalities were also performed, depending on the involved segments. The patients were compared with 100 normal subjects in whom an evaluation of the coronary artery was not indicative of valvular or myocardial abnormalities (Group IV. At follow-up, LV systolic indices were assessed via two-dimensional echocardiography at rest and during dobutamine stress echocardiography. Mitral annular motion was examined through mitral annulus systolic excursion (MASE. Peak transmitral flow velocities (TMFV and mitral valve area (MVA were also evaluated by means of continuous-wave Doppler. Results: A postoperative echocardiographic study showed significant mitral regurgitation (>=2+ in one patient in Group I, one patient in Group II, and none in Group III. None of the patients died. There was a noteworthy increase in TMFV with stress in all the groups, the increase being more considerable in the prosthetic ring groups (Group I from 1.10 ± 0.08 to 1.36 ± 0.13 m/s, Group II from 1.30 ± 0.11 to 1.59 ± 0.19 m/s, Group III from 1.33 ± 0.09 to 1.69 ± 0.21 m/s, and Group IV from 1.08 ± 0.08 to 1.21 ± 0.12 m

  14. Statins for aortic valve stenosis

    Luciana Thiago

    Full Text Available ABSTRACT BACKGROUND: Aortic valve stenosis is the most common type of valvular heart disease in the USA and Europe. Aortic valve stenosis is considered similar to atherosclerotic disease. Some studies have evaluated statins for aortic valve stenosis. OBJECTIVES: To evaluate the effectiveness and safety of statins in aortic valve stenosis. METHODS: Search methods: We searched the Cochrane Central Register of Controlled Trials (CENTRAL, MEDLINE, Embase, LILACS - IBECS, Web of Science and CINAHL Plus. These databases were searched from their inception to 24 November 2015. We also searched trials in registers for ongoing trials. We used no language restrictions. Selection criteria: Randomized controlled clinical trials (RCTs comparing statins alone or in association with other systemic drugs to reduce cholesterol levels versus placebo or usual care. Data collection and analysis: Primary outcomes were severity of aortic valve stenosis (evaluated by echocardiographic criteria: mean pressure gradient, valve area and aortic jet velocity, freedom from valve replacement and death from cardiovascular cause. Secondary outcomes were hospitalization for any reason, overall mortality, adverse events and patient quality of life. Two review authors independently selected trials for inclusion, extracted data and assessed the risk of bias. The GRADE methodology was employed to assess the quality of result findings and the GRADE profiler (GRADEPRO was used to import data from Review Manager 5.3 to create a 'Summary of findings' table. MAIN RESULTS: We included four RCTs with 2360 participants comparing statins (1185 participants with placebo (1175 participants. We found low-quality evidence for our primary outcome of severity of aortic valve stenosis, evaluated by mean pressure gradient (mean difference (MD -0.54, 95% confidence interval (CI -1.88 to 0.80; participants = 1935; studies = 2, valve area (MD -0.07, 95% CI -0.28 to 0.14; participants = 127; studies = 2

  17. Rheumatic fever in indigenous Australian children.

    Parnaby, Matthew G; Carapetis, Jonathan R


    Rheumatic heart disease (RHD) caused by acute rheumatic fever (ARF) is a disease of poverty, poor hygiene and poor living standards. RHD remains one of the major causes of childhood cardiac disease in developing nations. Within developed nations, there has been a dramatic drop in the prevalence of RHD because of the improvement of living standards, access to health care and the widespread availability of penicillin-based drugs. Despite a dramatic reduction of RHD in Australia overall, it continues to be a major contributor to childhood and adult cardiac disease in Indigenous communities throughout northern and central Australia. Currently, Australia has among the highest recorded rates of ARF and RHD in the world. The most accurate epidemiological data in Australia come from the Northern Territory's RHD control programme. In the Northern Territory, 92% of people with RHD are Indigenous, of whom 85% live in remote communities and towns. The incidence of ARF is highest in 5-14-year-olds, ranging from 150 to 380 per 100,000. Prevalence rates of RHD since 2000 have steadily increased to almost 2% of the Indigenous population in the Northern Territory, 3.2% in those aged 35-44 years. Living in remote communities is a contributing factor to ARF/RHD as well as a major barrier for adequate follow-up and care. Impediments to ARF/RHD control include the paucity of specialist services, rapid turnover of health staff, lack of knowledge of ARF/RHD by health staff, patients and communities, and the high mobility of the Indigenous population. Fortunately, the recently announced National Rheumatic Fever Strategy, comprising recurrent funding to the Northern Territory, Queensland and Western Australia for control programmes, as well as the creation of a National Coordination Unit suggest that RHD control in Australia is now a tangible prospect. For the disease to be eradicated, Australia will have to address the underpinning determinants of poverty, social and living conditions.

  18. Rheumatic manifestations of inflammatory bowel disease

    Tatiana Sofía Rodríguez-Reyna; Cynthia Martínez-Reyes; Jesús Kazúo Yamamoto-Furusho


    This article reviews the literature concerning rheumatic manifestations of inflammatory bowel disease(IBD), including common immune-mediated pathways,frequency, clinical course and therapy. Musculoskeletal complications are frequent and well-recognized manifestations in IBD, and affect up to 33% of patients with IBD. The strong link between the bowel and the osteo-articular system is suggested by many clinical and experimental observations, notably in HLA-B27 transgenic rats. The autoimmune pathogenic mechanisms shared by IBD and spondyloarthropathies include genetic susceptibility to abnormal antigen presentation,aberrant recognition of self, the presence of autoantibodies against specific antigens shared by the colon and other extra-colonic tissues, and increased intestinal permeability. The response against microorganisms may have an important role through molecular mimicry and other mechanisms. Rheumatic manifestations of IBD have been divided into peripheral arthritis, and axial involvement, including sacroiliitis,with or without spondylitis, similar to idiopathic ankylosing spondylitis. Other periarticular features can occur,including enthesopathy, tendonitis, clubbing, periostitis,and granulomatous lesions of joints and bones.Osteoporosis and osteomalacia secondary to IBD and iatrogenic complications can also occur. The management of the rheumatic manifestations of IBD consists of physical therapy in combination with local injection of corticosteroids and nonsteroidal anti-inflammatory drugs; caution is in order however, because of their possible harmful effects on intestinal integrity, permeability,and even on gut inflammation. Sulfasalazine,methotrexate, azathioprine, cyclosporine and leflunomide should be used for selected indications. In some cases, tumor necrosis factor-α blocking agents should be considered as first-line therapy.

  19. Nova técnica de transferência de cordas para sustentação das cúspides da valva mitral, após abertura completa de suas comissuras New technique for transference of chordae tendinae following mitral commissurotomy

    José Alberto Caliani


    Full Text Available Desde 1983, 40 pacientes consecutivos, portadores de estenose mitral com alterações subvalvares, tais como: fusão e encurtamento das cordas, associadas a sinéquia dos músculos papilares, foram submetidos a comissurotomia mitral a "céu aberto". Com o intuito de ganhar área efetiva maior de abertura da valva mitral (sem restrições, as comissuras foram abertas, amplamente, às vezes não respeitando as cordas que sustentam as cúspides. A insuficiência mitral provocada, em 4 casos, como conseqüência, foi corrigida mediante a transferência de 2 a 6 cordas, ao nível da borda livre da cúspide anterior, ou posterior, da valva, na região das comissuras. A presença de uma regurgitação central por falha na coaptação das cúspides valvares, foi tratada, em 12 casos, com o implante de anel profético de Carpentier. As anomalias do aparelho subvalvar foram abordadas pelas técnicas convencionais: desbridamento, ressecção e abertura dos músculos papilares. Dos 38 sobreviventes, 32 não apresentam sopro de regurgitação mitral e os 6 restantes, apenas sopro sistólico de +/+ +. A avaliação pós-operatória, mediante ecocardiografia bidemensional, demonstrou abertura valvar satisfatória e ausência de estenose residual. Os pacientes que apresentam sopro sistólico mitral residual foram estudados com Doppler, concluindo que se trata de regurgitação bem localizada e sem repercussão hemodinâmica. Esta nova técnica operatória pode ser "extensível" ao tratamento do prolapso da valva mitral.Since 1983, 40 consecutive patients with mitral stenosis and significant disease of the subvalvular apparatus underwent open heart mitral commissurotomy. The aim of the study was to evaluate the effects of an unrestricted dilatation of the two commissures followed by repair of the subsequent mitral regurgitation. The mitral regurgitation created by this procedure in 24 cases was corrected by transferring 2 to 6 chordae tendinae to the free border

  20. Mitral valve prolapse and body habitus in children.

    Arfken, C L; Schulman, P; McLaren, M J; Lachman, A S


    Mitral valve prolapse has generally been associated in adults with a thin body habitus. However, prior studies used biased samples or limited anthropometric measures. In addition, no information has been available on the subjective assessment of body habitus and diagnosis of mitral valve prolapse, especially in children. We conducted a cross-sectional study on 813 children with uniform assessment of anthropometric measures and mitral valve prolapse. Consistent with research conducted on adults, those subjects with mitral valve prolapse were lighter, thinner, and had, on average, lower values for several, quantifiable anthropometric parameters with the exception of height. However, the subjective assessment showed that while the assessment did not differ by diagnosis, those subjects with mitral valve prolapse were never described as fat. These data support an association between mitral valve prolapse and slender body habitus and extends it to children, thus underscoring the clinical importance that a thin body habitus may be a marker for mitral valve prolapse throughout the age span. This association may partly explain the observed genetic distribution of mitral valve prolapse.

    The edge-to-edge technique is one of the surgical procedures for anterior mitral leaflet prolapse. The purpose of this study is to evaluate the effect of this technique by using an in vitro mitral simulator. The results provide a useful suggestion and can be contributed to evidence-based medicine (EBM).

  3. Functional Mitral Regurgitation: Appraising the Evidence Behind Recommended Treatment Strategies.

    Samad, Zainab; Velazquez, Eric J


    Functional mitral regurgitation (MR) is the most common type of MR encountered in clinical practice. Because the disease arises from the ventricular aspect of the mitral valve apparatus, treatment therapies are less defined and outcomes are poor. In this review, the state of evidence for medical and surgical therapy in functional MR is appraised. Future directions for research in this area are also defined.

  5. Restrictive Atrial Septum Defect Becomes a Risk Factor for Norwood Palliation of Hypoplastic Left Heart Syndrome Only When It Is Combined with Mitral or Aortic Atresia.

    Sata, Sojiro; Sinzobahamvya, Nicodème; Arenz, Claudia; Zartner, Peter; Asfour, Boulos; Hraska, Viktor


    Restrictive atrial septal defect (ASD) is described as risk factor for Norwood procedure because of elevated pulmonary resistance. We hypothesized that it invariably could not cause pulmonary hypertension, unless it was combined with mitral valve or aortic valve atresia. We investigated how restrictive ASD influenced survival of patients with hypoplastic left heart syndrome (HLHS) who underwent Norwood operation. A total of 118 HLHS patients who underwent surgery between January 2005 and December 2012 were grouped into three groups. Group 1 included 31 patients with restrictive ASD combined with mitral or aortic atresia; Group 2 composed of 12 patients with restrictive ASD and mitral and aortic stenosis; Group 3 (n = 75) had no ASD restriction. Survival was determined for each group. Multivariate analysis was conducted to test risk factors for mortality. Mean follow-up was 26.3 ± 24.1 months. Survival was 78.7% ± 4.2% at 30-month interval and onward after Norwood procedure for the whole cohort; it was 43.8% ± 10.0%, 91.7% ± 8.0%, and 77.3% ± 5.0% for Group 1, 2, and 3, respectively. The difference was significant between Group 1 and Group 2 and 3: p < 0.001. Survival was similar for Group 2 and Group 3: p = 0.45. Combination of restrictive ASD and mitral or aortic atresia was found to be the sole risk factor for early and late mortality (odds ratio: 3.5, 95% confidence interval: 1.8-7.1, p < 0.001). Restrictive ASD only affects survival of HLHS patients following Norwood procedure if it is associated with mitral or aortic atresia. Georg Thieme Verlag KG Stuttgart · New York.

  6. Reparación de válvula mitral en insuficiencia mitral funcional isquémica y ecocardiografía: Serie de casos Mitral valve repair in ischemic functional mitral insufficiency and echocardiography: Case series

    Álvaro H Rodríguez


    Full Text Available La insuficiencia mitral isquémica es una complicación de la enfermedad coronaria que se asocia con resultados pobres. Su mecanismo básico es la remodelación del ventrículo izquierdo isquémico, que a su vez provoca desplazamiento de los músculos papilares, dilatación anular y tracción apical de las valvas. A pesar de que se ha comprobado que la reparación de la válvula mitral es superior al reemplazo de la válvula mitral para la corrección de la insuficiencia mitral severa orgánica, todavía hay un gran dilema en cuanto a qué procedimiento es el más adecuado para su tratamiento. Al parecer, en la actualidad la técnica de mayor uso para el tratamiento quirúrgico de pacientes con insuficiencia mitral isquémica severa, es la anuloplastia restrictiva de la válvula mitral; sin embargo, este procedimiento se asocia con 10% a 20% de persistencia post-operatoria temprana, y con 50% a 70% de tasas de recurrencia a cinco años. Además, la presencia de insuficiencia mitral isquémica severa persistente o recurrente, se asocia con mayor incidencia de eventos cardiacos y reducción de la supervivencia.Ischemic mitral valve insufficiency is a complication of coronary disease associated to poor results. Its basic mechanism is remodeling of ischemic left ventricle that causes the displacement of papillary muscles, annular dilation and valves apical traction. Although there is enough evidence that mitral valve repair is superior to mitral valve replacement for correction of severe organic mitral insufficiency, there is still a great dilemma as to which procedure is more suitable for its treatment. Apparently, now the most used technique for the surgical treatment of patients with severe ischemic mitral insufficiency is restrictive annuloplasty of the mitral valve; however, this procedure is associated to 10% to 20% of early post-operative persistence, and to 50% to 70% of recurrence rate at five years. Furthermore, the presence of persistent

  7. Mitral valve prolapse: associations with symptoms and anxiety.

    Arfken, C L; Lachman, A S; McLaren, M J; Schulman, P; Leach, C N; Farrish, G C


    Mitral valve prolapse has been studied extensively in the adult population, but less is known about it in children. Therefore, 813 children between 9 and 14 years of age were examined by a team of cardiologists and technicians. The children also responded to a questionnaire concerning the presence of symptoms and the What I Think and Feel anxiety instrument. The prevalence of mitral valve prolapse using auscultatory criteria was 4.2% (6.2% for girls, 2.3% for boys). Of those with mitral valve prolapse, 85% had a solitary click, 9% had a click and systolic murmur, and 6% had multiple clicks. Children with auscultatory mitral valve prolapse were less likely to have symptoms than those free of cardiac abnormalities. No difference in average anxiety scores was detected between the two groups. It is concluded that auscultatory mitral valve prolapse is common in children and not accompanied by an increased likelihood of symptoms or anxiety.

  8. Percutaneous mitral valve repair with MitraClip.

    Cilingiroğlu, Mehmet; Salinger, Michael


    Over the last decade, several technologies have been developed for percutaneous repair of the mitral valve for patients with severe mitral regurgitation (MR) and at high-risk for the traditional open-heart mitral valve repair or replacement. Among them, MitraClip has emerged as the only clinically safe and effective method for percutaneous mitral valve repair. It is adapted from the surgical technique that was initially described by Dr. Alfieri and his group by placement of a suture approximating the edges of the mitral leaflets at the origin of the MR jet, leading to creation of so-called bow-tie or double orifice with significant reduction in the MR jet. Here, we review the details of the technology, its procedural perspective as well as currently available data for its safety and effectiveness on a case-based report.

  9. Weather conditions can influence rheumatic diseases.

    Vergés, Josep; Montell, Eulàlia; Tomàs, Elena; Cumelles, Gemma; Castañeda, Guido; Marti, Núria; Möller, Ingrid


    In daily clinical practice, many patients attribute joint pain to weather conditions. There is little information published on this subject and most of it is contradictory. The objective of this study was to evaluate the effect of climatic conditions in rheumatic patients. The present work was carried out with patients attending the Instituto Poal de Reumatologia of Barcelona and the data were analyzed by Bioibérica Farma (Spain). It was a prospective, double-blind study including 92 patients with rheumatic disorders (80 with osteoarthritis, 12 with rheumatoid arthritis) compared to a control group of 42 subjects. The evaluation of pain (Huskisson VAS) and functional capacity (Health Assessment Questionnaire, HAQ) were determined daily during one month. The climatic variables studied were temperature, humidity and barometric pressure. The results obtained have been subject to binary regression analysis. Our data demonstrate that osteoarthritic patients experience increased joint pain in response to a decrease in pressure, indicating that low atmospheric pressure conditions exacerbate joint pain in these patients. Our work also suggests that some meteorological variables affect the occurrence of pain in rheumatoid arthritis, since we have found that low temperature increases the risk of joint pain. Therefore, these data suggest that in the future it may be possible to modulate pharmacological and non-pharmacological treatments for some osteoarthritic patients depending on the predictable weather conditions in order to avoid, as much as possible, the disease-associated joint pain and functional incapacity, thus improving patients' quality of life.

  10. Management of rheumatic diseases during pregnancy.

    Elliott, Amy B; Chakravarty, Eliza F


    Systemic rheumatic diseases commonly affect women during the childbearing years. Many women with these diseases may be contemplating pregnancy or discover an inadvertent pregnancy, leading to concerns regarding medication use, changes in disease activity during pregnancy, safety of lactation, and future ability to care for a child given the presence of chronic illnesses. There are outstanding reviews that summarize the safety and use of immunosuppressive medications during pregnancy. However, in addition to medication use, providers need to be aware of the available data regarding fertility, pregnancy outcomes, delivery, and lactation issues that may be specific to individual diseases. Optimally, women should plan pregnancies to occur around times of disease quiescence, several months after potentially teratogenic medications have been discontinued. The course of the underlying rheumatic disease during pregnancy is variable, and there are no specific clinical or laboratory variables that consistently predict disease improvement or worsening during pregnancy. Recent data suggest that increased disease activity in women with most autoimmune diseases during pregnancy may lead to increased risk of premature delivery, low-birth-weight infants, and other adverse pregnancy outcomes. Arthritis involving the cervical spine and hips may impact delivery and must be considered by both obstetricians and obstetric anesthesiologists. Data are mixed regarding the impact of breastfeeding on underlying autoimmune diseases; the choice to continue breastfeeding is a personal decision.

  11. Towards a Vaccine Against Rheumatic Fever

    L. Guilherme


    Full Text Available Rheumatic fever (RF is an autoimmune disease which affects more than 20 million children in developing countries. It is triggered by Streptococcus pyogenes throat infection in untreated susceptible individuals. Carditis, the most serious manifestation of the disease, leads to severe and permanent valvular lesions, causing chronic rheumatic heart disease (RHD. We have been studying the mechanisms leading to pathological autoimmunity in RF/RHD for the last 15 years. Our studies allowed us a better understanding of the cellular and molecular pathogenesis of RHD, paving the way for the development of a safe vaccine for a post-infection autoimmune disease. We have focused on the search for protective T and B cell epitopes by testing 620 human blood samples against overlapping peptides spanning 99 residues of the C-terminal portion of the M protein, differing by one amino acid residue. We identified T and B cell epitopes with 22 and 25 amino acid residues, respectively. Although these epitopes were from different regions of the C-terminal portion of the M protein, they showed an identical core of 16 amino acid residues. Antibodies against the B cell epitope inhibited bacterial invasion/adhesion in vitro. Our results strongly indicated that the selected T and B cell epitopes could potentially be protective against S. pyogenes.

  12. Metabolic syndrome in inflammatory rheumatic diseases

    G. La Montagna


    Full Text Available Toward the end of the last century a better knowledge of cardiovascular (CV risk factors and their associations led investigators to propose the existence of a unique pathophysiological condition called “metabolic” or “insulin resistance syndrome”. Among all, insulin-resistance and compensatory hyperinsulinemia are considered its most important treatment targets. Different definitions have been provided by World Health Organization (WHO and by The Third Report of The National Cholesterol Education Program’s Adult Treatment Panel (NCEP-ATP III. In particular, abdominal obesity, hypertension, low HDL cholesterol and hyperglicemia are the most common items used for its definition. The presence of MetS is effective in predicting the future risk of diabetes and coronaropathies. The evidence of a higher CV risk rate among different rheumatic inflammatory diseases has recently been associated with high prevalence of MetS in some cases. Rheumatoid or psoriatic arthritis have the large series among arthritis, whereas systemic lupus erythematosus among connective tissue disorders. This review analyses all most important studies about the evidence of MetS in rheumatic patients and the main clinical and prognostic significance of this relation.

    Full Text Available Summary Aim: to assess the efficacy and tolerability of Consupren (Galena, Chekia in some rheumatic diseases. Material and methods. Three months’ therapy by Consupren was studied in 12 patients: 4 with SLE, 4 with Behcet’s disease, 2 with rheumatoid arthritis with systemic manifestations, 2 with juvenile rheumatoid arthritis. Sandimmune therapy was changed for Consupren in 9 patients. All patients were controlled for the level of serum creatinine and AD and had consultations with ophtalmologist. Results. 3 SLE patients treated by Consupren demonstrated decreasing of proteinuria, disease activity by SLAM and SLEDA1, the fourth patient demonstrated fading of diskoid rash and normalizing of temperature. Patients with Behcet’s disease had no episodes of ulcerous stomatitis and uveitis exacerbation, in one patient stable nodular erythema disappeared. Patients with JRA improved articular syndrome, normalized temperature, reduced acute phase indices. Both patients continue taking Consupren, RA patients had long term of onset of the disease and 111-IV radiological stage , thus the effect on the articular syndrome was not so demonstrative but the activity of the disease reduced. Conclusion: consupren is effective and well tolerable drug for patients with systemic manifestations of rheumatic diseases. No side effects were noticed.

  15. Porcine mitral valve interstitial cells in culture.

    Lester, W; Rosenthal, A; Granton, B; Gotlieb, A I


    There are connective tissue cells present within the interstitium of the heart valves. This study was designed to isolate and characterize mitral valve interstitial cells from the anterior leaflet of the mitral valve. Explants obtained from the distal part of the leaflet, having been scraped free of surface endocardial cells, were incubated in medium 199 supplemented with 10% fetal bovine serum. Cells grew out of the explant after 3 to 5 days and by 3 weeks these cells were harvested and passaged. Passages 1 to 22 were characterized in several explant sets. The cells showed a growth pattern reminiscent of fibroblasts. Growth was dependent on serum concentration. Cytoskeletal localization of actin and myosin showed prominent stress fibers. Ultrastructural studies showed many elongated cells with prominent stress fibers and some gap junctions and few adherens junctions. There were as well cells with fewer stress fibers containing prominent Golgi complex and dilated endoplasmic reticulum. In the multilayered superconfluent cultures, the former cells tended to be on the substratum of the dish or surface of the multilayered culture, whereas the latter was generally located within the layer of cells. Extracellular matrix was prominent in superconfluent cultures, often within the layers as well. Labeling of the cells with antibody HHF 35 (Tsukada T, Tippens D, Gordon D, Ross R, Gown AM: Am J Pathol 126:51, 1987), which recognizes smooth muscle cell actin, showed prominent staining of the elongated stress fiber-containing cells and much less in the secretory type cells. These studies show that interstitial mitral valve cells can be grown in culture and that either two different cell types or one cell type with two phenotypic expressions is present in culture.

  17. Idiopathic subglottic stenosis: a familial predisposition.

    Dumoulin, Elaine; Stather, David R; Gelfand, Gary; Maranda, Bruno; Maceachern, Paul; Tremblay, Alain


    Idiopathic subglottic stenosis is a narrowing of the trachea at the level of the cricoid cartilage of unknown etiology. It is a rare condition for which the real incidence has never been established owing to the difficulty of making the diagnosis. Although there is a female preponderance, no familial cases have been reported in the literature. We describe two pairs of sisters as well as a mother and daughter presenting with idiopathic subglottic stenosis. All known causes of tracheal stenosis were excluded, including prolonged intubation, surgery, autoimmune and inflammatory disorders, infection and gastroesophageal reflux disease. These are the first cases reported in the literature that suggest a genetic predisposition for idiopathic subglottic stenosis.

  18. Pseudopapillary fibroelastoma of the mitral valve.

    Madu, E; Myles, J; Fraker, T D


    Papillary fibroelastomas are well-recognized benign cardiac neoplasms. They are primarily asymptomatic, but occasionally are associated with neurologic and cardiac symptoms. Pseudopapillary fibroelastomas presenting with usual clinical and echocardiographic manifestations of papillary fibroelastoma but lacking characteristic histologic features have not been described previously. This article describes a 42-year-old, previously healthy female admitted with sudden hemiparesis and dysarthria. Symptoms completely resolved within 4 days. Extensive investigations revealed no etiology except for a pedunculated mitral valve mass with echocardiographic appearance suggestive of papillary fibroelastoma. Histologic staining, however, failed to reveal characteristic features of papillary fibroelastoma.

    Objective To evaluate the transesophageal echocardiography(TEE) and surgical treatment to cardiac papillary fibroelastomas (CPFE). Methods CPFE is a rare benign tumor occuring mainly in valves and often revealed by serious cerebral, coronary and peripheral embolism or even sudden death. We report a case of mitral PFE diagnosed by transesophageal echocardiography (TEE), and surgical resection was performed. Results Surgical intervention is successful, and the follow-up courses are uneventful. Conclusion TEE is helpful to diagnosis and guiding the operation. Operation is recommended to prevent recurrent embolization complications.

Initial precardiopulmonary bypass TEE was used to confirm MV dysfunction, TV involvement and to assess LV function. On the 1 st run bypass (RBP, the MV commissurotomy was performed in 27 pts (23 with MS and 4 with MS+MR; the MV was replaced with BV (pericardial #21 to #29 in 18 pts (6 with BV dysfunction and 12 with MS+MR and the MV repair was performed in all of 19 pts with MR. The 2nd RBP was required in 7 pts (11%: 1 pt with MR; 4 pts with MS+MR and 2 pts with MS. TEE caused changes in pre pump plans in 9 pts with TV lesions and in 10 pts with MS or MS+MR - preservation of native in 6 pts in which replacement was planned. Thus intraoperative TEE provides helpful information in MV surgery and can help avoid a mitral replacement in pts with MS or MS+MR.

  3. The control of rheumatic fever and rheumatic heart disease: a call to raise the awareness.

    Kheir, Sirageldin M; Ali, Sulafa Khalid M


    Although the incidence of rheumatic fever (RF) and rheumatic heart disease (RHD) has declined in the developed world and many developing countries, yet it is still high in many countries including Sudan. The decline of frequency of RF in these countries is largely due to improved medical services leading to wide use of antibiotics to treat bacterial pharyngitis. In many developing countries, the incidence is decreased due to development of integrated control programs. Depending on secondary prophylaxis alone was shown to be ineffective, therefore, many countries, including Sudan initiated control programs that utilize both primary and secondary prevention together with increasing awareness and surveillance. The new program started in 2012 in Sudan in order to achieve its goal of reducing mortality of RHD by 25% in individual less than 25 years of age by year 2025. This article throws light on RF and RHD and its control program in Sudan.

  4. Use of autologous pericardium for mitral leaflet reconstruction in a child with endocarditis

    Olcay Murat Disli


    Full Text Available We present a case of successful repair of the mitral valve for active infective endocarditis. Mitral valve repair was performed through debridement of vegetation and abscess, resection and repair of the posterior mitral leaflet and posterior repair with autologous pericardium. Postoperative period was uneventfully, with no evidence of recurrent infection, and echocardiogram showed mitral valve competence with mild mitral regurgitation. We demonstrate that valve repair is a feasible choice in cases of active endocarditis in children.

  5. Nutrition and pediatric rheumatic diseases. Hypothesis: cytokines modulate nutritional abnormalities in rheumatic diseases.

    Ostrov, B E


    Growth abnormalities are common in pediatric rheumatic diseases. Studies suggest that effects of inflammation such as anorexia, and adipose and muscle tissue breakdown contribute to the nutritional and growth aberrations. The effects of the various cytokines produced during inflammation create a vicious cycle of anorexia and increased catabolism, and may be responsible for the nutritional deficits seen. In future, specific treatment with anticytokine monoclonal antibodies may block these effects, minimizing the nutritional consequences of inflammation.

    Islam, M I; Talukder, M K; Islam, M M; Laila, K; Rahman, S A


    Macrophage activation syndrome (MAS) is a potentially fatal complication of rheumatic disorders, which commonly occurs in systemic juvenile idiopathic arthritis (sJIA).This study was carried out with the aims of describing the clinical features, laboratory findings and outcomes of MAS associated with paediatric rheumatic diseases in the Department of Paediatrics, Bangabandhu Sheikh Mujib Medical University (BSMMU) and compare these results with previous studies on MAS. This retrospective study was conducted in the paediatric rheumatology wing of the Department of Paediatrics, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. Clinical and laboratory profile of all the diagnosed cases of MAS were analyzed from the medical records from January 2010 to July 2015. Among 10 MAS patients, 6 were female and 4 were male. Seven patients of systemic JIA, two patients of SLE and one patient with Kawasaki Disease developed MAS in their course of primary disease. Mean duration of primary disease prior to development of MAS was 2.9 years and mean age of onset was 9.1 years. High continued fever and new onset hepatosplenomegaly were the hallmark of the clinical presentation. White blood cell count and platelet count came down from the mean of 16.2 to 10.2×10⁹/L and 254 to 90×10⁹/L. Mean erythrocyte sedimentation rate was dropped from 56 to 29 mm/hr. Six patients had abnormal liver enzyme level (ALT) and 5 had evidence of coagulopathy (prolonged prothrombin time and APTT) at the onset of disease. Hyperferritinnemia were found in all the patients. Bone marrow study was done in 5 patients but features of hamophagocytosis were found only in 2 patients. All patients received intravenous steroid and 3 patients who did not respond to steroid received additional cyclosporine. Mortality rate was 30% in this series. Macrophage activation syndrome is a fatal complication of paediatric rheumatic diseases among which s-JIA was predominant. Early diagnosis and

    Saurav, Alok; Alla, Venkata Mahesh; Kaushik, Manu; Hunter, Claire C; Mooss, Aryan V


    Long-term superiority of mitral valve (MV) repair compared with replacement is well established in degenerative MV disease. In rheumatic heart disease, its advantages are unclear and it is often performed in conjunction with aortic valve (AV) replacement. Herein, we performed a systematic review and meta-analysis comparing outcomes of MV repair vs replacement in patients undergoing concomitant AV replacement. PubMed, Cochrane and Web of Science databases were searched up to 25 January 2014 for English language studies comparing outcomes of MV repair vs replacement in patients undergoing simultaneous AV replacement. Data of selected studies were extracted. Study quality, publication bias and heterogeneity were assessed. Analysis was performed using a random effects model (meta-analysis of observational studies in epidemiology recommendation). A total of 1202 abstracts/titles were screened. Of these, 20 were selected for full text review and 8 studies (3924 patients) were included in the final analysis: 1255 underwent MV repair and 2669 underwent replacement. Late outcome data were available in seven studies (cumulative follow-up: 15 654 patient-years). The early (in hospital and up to 30 days post-surgery) mortality [risk ratio (RR): 0.68, 95% confidence interval (CI): 0.53-0.87, P = 0.003] and late (>30 days post-surgery) mortality (RR: 0.76, 95% CI: 0.64-0.90 P = 0.001) were significantly lower in the MV repair group compared with the MV replacement group. The MV reoperation rate (RR: 1.89, 95% CI: 0.87-4.10, P = 0.108), thromboembolism (including valve thrombosis) (RR: 0.65, 95% CI: 0.38-1.13, P = 0.128) and major bleeding rates (RR: 0.88, 95% CI: 0.49-1.57, P = 0.659) were found to be comparable between the two groups. In a separate analysis of studies with exclusively rheumatic patients (n = 1106), the early as well as late mortality benefit of MV repair was lost (RR: 0.92, 95% CI: 0.44-1.90, P = 0.81 and RR: 0.69, 95% CI: 0.39-1.22, P = 0.199, respectively

  10. Recurred Post-intubation Tracheal Stenosis Treated with Bronchoscopic Cryotherapy.

    Jung, Ye-Ryung; Taek Jeong, Joon; Kyu Lee, Myoung; Kim, Sang-Ha; Joong Yong, Suk; Jeong Lee, Seok; Lee, Won-Yeon

    Post-intubation tracheal stenosis accounts for the greatest proportion of whole-cause tracheal stenosis. Treatment of post-intubation tracheal stenosis requires a multidisciplinary approach. Surgery or an endoscopic procedure can be used, depending on the type of stenosis. However, the efficacy of cryotherapy in post-intubation tracheal stenosis has not been validated. Here, we report a case of recurring post-intubation tracheal stenosis successfully treated with bronchoscopic cryotherapy that had previously been treated with surgery. In this case, cryotherapy was effective in treating web-like fibrous stenosis, without requiring more surgery. Cryotherapy can be considered as an alternative or primary treatment for post-intubation tracheal stenosis.

  11. Chronic mitral regurgitation detected on cardiac MDCT: differentiation between functional and valvular aetiologies.

    Killeen, Ronan P


    OBJECTIVE: To determine whether cardiac computed tomography (MDCT) can differentiate between functional and valvular aetiologies of chronic mitral regurgitation (MR) compared with echocardiography (TTE). METHODS: Twenty-seven patients with functional or valvular MR diagnosed by TTE and 19 controls prospectively underwent cardiac MDCT. The morphological appearance of the mitral valve (MV) leaflets, MV geometry, MV leaflet angle, left ventricular (LV) sphericity and global\\/regional wall motion were analysed. The coronary arteries were evaluated for obstructive atherosclerosis. RESULTS: All control and MR cases were correctly identified by MDCT. Significant differences were detected between valvular and control groups for anterior leaflet length (30 +\\/- 7 mm vs. 22 +\\/- 4 mm, P < 0.02) and thickness (3.0 +\\/- 1 mm vs. 2.2 +\\/- 1 mm, P < 0.01). High-grade coronary stenosis was detected in all patients with functional MR compared with no controls (P < 0.001). Significant differences in those with\\/without MV prolapse were detected in MV tent area (-1.0 +\\/- 0.6 mm vs. 1.3 +\\/- 0.9 mm, P < 0.0001) and MV tent height (-0.7 +\\/- 0.3 mm vs. 0.8 +\\/- 0.8 mm, P < 0.0001). Posterior leaflet angle was significantly greater for functional MR (37.9 +\\/- 19.1 degrees vs. 22.9 +\\/- 14 degrees , P < 0.018) and less for valvular MR (0.6 +\\/- 35.5 degrees vs. 22.9 +\\/- 14 degrees, P < 0.017). Sensitivity, specificity, and positive and negative predictive values of MDCT were 100%, 95%, 96% and 100%. CONCLUSION: Cardiac MDCT allows the differentiation between functional and valvular causes of MR.

  12. Defensins: Potential Effectors in Autoimmune Rheumatic Disorders

    Stefan Vordenbäumen


    Full Text Available Defensins are small cationic peptides with antimicrobial properties. They constitute a highly conserved innate immune defense mechanism across species. Based on the arrangement of disulfide-bonds, α- and β-defensins are distinguished in humans. Both types of defensin comprise several distinct molecules that are preferentially expressed at epithelial surfaces and in blood cells. In the last decade, multiple immunomodulatory functions of defensins have been recognized, including chemotactic activity, the promotion of antigen presentation, and modulations of proinflammatory cytokine secretion. These findings suggested a role for defensins not only as a first line of defense, but also as connectors of innate and adaptive immune responses. Recently, increasingly accumulating evidence has indicated that defensins may also be involved in the pathogenesis of autoimmune rheumatic disorders such as systemic lupus erythematosus and rheumatoid arthritis. The current review summarizes the data connecting defensins to autoimmunity.

  13. Refractory Rheumatic Disorder: Atypical Postpregnancy Osteoporosis

    Cindy Mourgues


    Full Text Available This is a case report on a young patient with severe osteoporosis that was initially revealed when she presented with polyarthralgia during her second pregnancy. Postpartum, the pain increased and her X-ray did not show any abnormalities. A bone scintigraphy was performed. It indicated an inflammatory rheumatic disorder. Six months after partum, an investigation of right coxalgia revealed a spontaneous basicervical fracture. Given the persistent polyarthralgia, the patient underwent a new scintigraphy, which revealed areas of what looked to be old rib and L1 fractures. A subsequent full body magnetic resonance imaging (MRI scan revealed signal abnormalities that could indicate multiple lower limb bone fractures. Despite exhaustive biological, radiological, and histological testing, no secondary cause for the osteoporosis was found. The patient was started on teriparatide. We finally concluded that, despite the atypical presentation, the patient was suffering from postpregnancy osteoporosis. It is possible that the frequency of occurrence of this still poorly understood disease is underestimated.

  14. Mean platelet volume in acute rheumatic fever.

    Sert, Ahmet; Aypar, Ebru; Odabas, Dursun


    Acute rheumatic fever (ARF) is still an endemic disease, especially among school-aged children in developing countries. Mean platelet volume (MPV), which is commonly used as a measure of platelet size, indicates the rate of platelet production and platelet activation. We aimed to investigate MPV in children with ARF. The study population consisted of 40 children with ARF (32 patients with carditis and 8 patients without carditis) and 40 healthy control subjects. White blood cell (WBC) and platelet counts were significantly higher and MPV values were significantly lower in patients with ARF during the acute stage when compared to controls. Erythrocyte sedimentation rate (ESR) and C-reactive protein values significantly decreased in patients with ARF after the treatment when compared to baseline, whereas MPV values increased. MPV values were negatively correlated with ESR and WBC, and platelet counts. In conclusion, during the acute stage of ARF, MPV values were lower when compared to controls.

  15. MicroRNAs in autoimmune rheumatic diseases

    G.D. Sebastiani


    Full Text Available The etiology of autoimmune diseases remains largely unknown. In recent years, besides genetic factors, several studies proposed that the epigenome may hold the key to a better understanding of autoimmunity initiation and perpetuation. More specifically epigenetic regulatory mechanisms comprise DNA methylation, a variety of histone modifications, and microRNA (miRNA activity, all of which act upon gene and protein expression levels. In particular it is well known that epigenetic mechanisms are important for controlling the pattern of gene expression during development, the cell cycle, and the response to biological or environmental changes. In the present review a description of the most frequent epigenetic deregulations, in particular the role of miRNA, in rheumatic autoimmune disorders will be analyzed.

  16. Calprotectin in rheumatic diseases: a review.

    Kopeć-Mędrek, Magdalena; Widuchowska, Małgorzata; Kucharz, Eugeniusz J


    Calprotectin also known as MRP8/14 or S100A8/A9 is a heterodimeric complex of two S100 calcium-binding proteins: myeloid-related protein 8 (MRP-8 or S100A8) and MRP-14 (or S100A9). At present, according to many authors, it is considered that calprotectin MRP8/14 is a potentially more sensitive biomarker of disease activity in rheumatoid disease than conventional inflammatory indices such as the erythrocyte sedimentation rate, C-reactive protein and others. A review of the literature on concentration of calprotectin in patients with some rheumatic diseases (rheumatoid arthritis, juvenile idiopathic arthritis, adult-onset Still's disease, systemic vasculitis, polymyalgia rheumatica, ankylosis spondylitis, systemic lupus erythematosus, and primary Sjögren's syndrome) is presented.

    Rufenach, C; Burmester, G-R; Zeidler, H; Radbruch, A


    The foundation of the competence network for rheumatology, which is funded by the "Bundesministerium für Bildung und Forschung" (BMBF) since 1999, succeeded to create a unique research structure in Germany: medical doctors and scientists from six university rheumatology centres (Berlin, Düsseldorf, Erlangen, Freiburg, Hannover und Lübeck/Bad Bramstedt) work closely together with scientists doing basic research at the Deutsches Rheuma-Forschungszentrum (DRFZ), with rheumatological hospitals, reha-clinics, and rheumatologists. Jointly they are searching for causes of systemic inflammatory rheumatic diseases and try to improve therapies-nationwide and with an interdisciplinary approach. The primary objective of this collaboration is to transfer new scientific insights more rapidly in order to improve methods for diagnosis and patients treatment.
