    High morbidity and mortality due to Rheumatic heart disease (RHD) associated with females is mainly because of late diagnosis on one hand and socioeconomic reasons on the other hand. Poor referral to tertiary care centres leads to delayed diagnosis which results in complications. The objectives of this cross-sectional descriptive study was to assess the frequency of severe mitral stenosis in woman of child bearing age, having pure mitral stenosis (MS) secondary to rheumatic heart disease. Methods: Two hundred and fifty women of child bearing age with RHD were enrolled in the study using consecutive non-probability sampling technique. Out of these 250 patients, cases of pure MS were selected. Patients with associated mitral regurgitation and aortic valve disease were excluded. After admission, assessment of mitral valve stenosis was done with 2D colour Doppler echocardiography. Results: Out of 250 consecutive patients of rheumatic carditis, 110 (44%) patients had pure mitral valve stenosis, 85 (34%) had stenosis with mitral regurgitation and 55 (22%) patients had both mitral and aortic valve problem of varying severity. Among 110 patients with pure mitral valve stenosis, 48 (43.6%) had severe mitral valve stenosis. Severe mitral valve gradient (MVG) and high pulmonary artery pressure (PAP) was observed in 66 (60%) and 49 (44.5%) of the patients respectively. Conclusion: This high frequency can be linked to lack of early detection of the disease at primary level, poor management of throat infections and poor rheumatic fever prophylaxis at community level.

    We report a 5-year-old boy weighing 11 kg, with severe mitral valve stenosis of rheumatic aetiology, who underwent successful percutaneous transluminal mitral commissurotomy (PTMC) with valvuloplasty balloon. Postprocedural mean pressure gradient across the mitral valve decreased to 6 mmHg from an initially recorded value of 22 mmHg. In addition to symptomatic improvement, the mitral valvular area increased from 0.4 to 0.8 cm(2) without significant change in mitral regurgitation. At 1- and 3-month follow up, transthoracic echocardiography revealed further improvement with an increase in mitral valve area to 1.0 cm(2), a decrease in pulmonary arterial pressure, and a mean mitral valve pressure gradient of 8 mmHg with trivial mitral regurgitation. To best of our knowledge, this is the first successful PTMC procedure performed in the youngest and smallest ever reported child with rheumatic mitral stenosis (MS). We conclude that PTMC with valvuloplasty balloon could be a logical alternative to surgery in young patients with rheumatic MS.

    Full Text Available Dilation and hypertrophy of the atria occur in patients with valvular heart disease especially in mitral regurgitation, mitral stenosis or tricuspid abnormalities. In sub-saharan Africa, rheumatic fever is still the leading cause of valvular heart disease. We report a case of an unusual giant right atrium in context of rheumatic stenosis and severe tricuspid regurgitation in a 58-year-old woman.

    Mitral valve replacement with posterior leaflet preservation was shown beneficial for postoperative left vetricular (LV) performance in patients with mitral regurgitation. Some authors find it beneficial even for the long term LV function. We investigated a long term effect of this technique in patients with rheumatic mitral stenosis. We studied 20 patents with mitral valve replacement due to rheumatic mitral stenosis, in the period from January 1988 to December 1989. In group A (10 patients) both leaflets and coresponding chordal excision was performed, while in group B (10 patients) the posterior leaflet was preserved. In all patients a Carbomedics valve was inserted. We compared clinical pre and postoperative status, as well as hemodynamic characteristics of the valve and left ventricle in both groups. Control echocardiographyc analysis included: maximal (PG) and mean (MG) gradients; effective valve area (AREA); telediastolic (TDV) and telesystolic (TSV) LV volume; stroke volume (SV); ejection fraction (EF); fractional shortening (FS) and segmental LV motion. The mean size of inserted valve was 26.6 in group A and 27.2 in group B. Hemodynamic data: PG (10.12 vs 11.1); MG (3.57 vs 3.87); AREA (2.35 vs 2.30); TDV 126.0 vs 114.5); TSV (42.2 vs 36.62); SV (83.7 vs 77.75); EF (63.66 vs 67.12); FS (32.66 vs 38.25). Diaphragmal segmental hypokinesis was evident in one patient from group A and in two patients from group B. In patients with rheumatic stenosis, posterior leaflet preservation did not have increased beneficial effect on left ventricular performance during long-term follow-up. An adequate posterior leaflet preservation does not change hemodynamic valvular characteristics even after long-term follow-up.

    Background: Rheumatic heart disease is a common ailment in Pakistan and Mitral stenosis is its flag bearer Severity of mitral stenosis is the key factor in deciding for mitral valve surgery. Methods: This case series study was conducted at Ayub Teaching Hospital .Cases of Rheumatic heart disease with mitral stenosis were diagnosed clinically. 2D echocardiography was used to find severity of mitral stenosis. Data was entered into SPSS-17.0 and results were recorded and analysed. Pearsons two tailed correlation was used to find the correlation between presence of tricuspid regurgitation in patients with severe mitral stenosis, p was <0.05. Results: A total 35 patients with pure mitral stenosis were included in study, out of which 8 were male and 27 were females. Mean age in males was 34.5±15.85 years while in females it was 31±8 years. Twenty-two out of 35 (62.86 percent) patients had tricuspid regurgitation while 13 out 35 (37.14 percent) had no tricuspid regurgitation. Mean (MVA) mitral valve area in patients with tricuspid regurgitation was 0.84±0.3 cm/sup 2/ while mean (MVA) mitral valve area in patients without tricuspid regurgitation was 1.83±0.7 cm/sup 2/. Mean left atrial (L.A) size was 45.23±1.5mm/sup 2/ in patients with tricuspid regurgitation, while it was 44.13±6.14mm/sup 2/ in patients without tricuspid regurgitation. Mean RSVP was 57.5mmHg in patients with tricuspid regurgitation while RSVP could not be calculated in patients without tricuspid regurgitation. Conclusions: It was concluded that tricuspid regurgitation was strongly associated with severe mitral stenosis as almost all patients with severe mitral stenosis had tricuspid regurgitation and none of the patients with mild mitral stenosis had tricuspid regurgitation.

    Objective: To evaluate safety and effect of percutaneous balloon mitral valvuloplasty (PBMV) for patients with rheumatic mitral stenosis and left atrial thrombi. Methods: PBMV was performed in 27 patients with rheumatic mitral stenosis and left atrial thrombi. 19 cases of left atrial fresh thrombi revealed by trans-esophageal echocardiography (TEE) received warfarin orally for 3-6 months before PBMV. Results: PBMV was successful in all cases of mitral stenosis and left atrial thrombi. Left atrial fresh thrombi was completely resolved in 9 cases and became smaller chronic organized thrombi in 10 cases after warfarin anticoagulation treatment among 19 cases of left atrial fresh thrombi revealed by TEE. In 5 cases of left atrial chronic organized thrombi shown only transthoracic echocardiography and without anticoagulation treatment, one case had cerebral embolism. No complication occurred in other cases. Conclusions: The study showed that patients with rheumatic mitral stenosis and atrial fibrillation should have routine TEE. PBMV for rheumatic mitral stenosis with left atrial thrombi after anticoagulation treatment is safe and effective

    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

    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.

    Full Text Available Mitral stenosis due to rheumatic heart disease is not common in the United States but is common in the developing world because rheumatic fever is still occurring frequently. Symptoms usually gradually occur in the young adult (most commonly female. Atrial fibrillation is a common accompanying rhythm in patients with proven mitral stenosis. The main physiologic event is a pressure gradient between the left atrium and the left ventricle. Diagnosis is relatively straight forward using physical exam and simple laboratory studies such as Chest X-Ray (elevated Left main stem bronchus, Double Density indicating enlarged left atrium and ECG (P-Mitrale. Cardiac ultrasound confirms the clinical diagnosis (Doming of mitral valve in diastole, Hockey stick deformity of the anterior mitral valve leaflet, large left atrium, Doppler estimation of valve gradient. Mitral commisurotomy (surgical or Balloon is warranted if the valve is pliable and not heavily calcified.

    The aim of this study was to evaluate the factors associated with the development of atrial fibrillation (AF) in patients with rheumatic mitral stenosis (MS). A total of 146 consecutive patients with rheumatic MS were screened. They were accepted to be in AF group and sinus rhythm group according to their rhythm in the baseline ECG. After screening, 38 patients were excluded due to hyperthyroidism (n = 13), chronic obstructive pulmonary disease (n = 22), malignancy (n = 2) and rheumatoid arthritis (n = 1). Therefore, remaining 108 patients, 74 of whom in sinus rhythm (MS-SR) and 34 of whom in AF (MS-AF) constituted study population. Fourty age- and gender-matched patients constituted control group. Factors associated with development of AF in multivariable analysis included High sensitivity C reactive protein (P = 0.005; odds ratio, 3.44; 95% confidence interval, 1.44-8.22), N-terminal of brain natriuretic peptide precursor (P brain natriuretic peptide precursor and left atrial diameter are associated with development AF in patients with MS.

    Although mitral stenosis (MS) due to pannus overgrowth after mitral valve repair for rheumatic mitral regurgitation (MR) is not uncommon, it is extremely rare in relation to non-rheumatic mitral regurgitation. Whilst it has been suggested that the rigid annuloplasty ring induces pannus overgrowth in the same manner as the flexible ring, to date only in cases using the flexible ring has pannus formation been confirmed by a pathological examination after redo surgery. The case is described of a woman who had undergone mitral valve repair using a 28 mm rigid ring three years previously because of non-rheumatic MR, and subsequently suffered from MS due to pannus formation over the annuloplasty ring. To the present authors' knowledge, this is the first report of MS due to pannus formation after mitral valve repair using a rigid annuloplasty ring to treat non-rheumatic MR documented at reoperation.

    Mitral stenosis was diagnosed in 15 young to middle-aged dogs. There were 5 Newfoundlands and 4 bull terriers affected, suggesting a breed predisposition for this disorder. Clinical signs included cough, dyspnea, exercise intolerance, and syncope. Soft left apical diastolic murmurs were heard only in 4 dogs, whereas 8 dogs had systolic murmurs characteristic of mitral regurgitation. Left atrial enlargement was the most prominent radiographic feature. Left-sided congestive heart failure was detected by radiographs in 11 dogs within 1 year of diagnosis. Electrocardiographic abnormalities varied among dogs and included atrial and ventricular enlargement, as well as atrial and ventricular arrhythmias. Abnormalities on M-mode and two-dimensional echocardiograms included abnormal diastolic motion of the mitral valve characterized by decreased leaflet separation, valve doming, concordant motion of the parietal mitral valve leaflet, and a decreased E-to-F slope. Increased mitral valve inflow velocities and prolonged pressure half-times were detected by Doppler echocardiography. Cardiac catheterization, performed in 8 dogs, documented a diastolic pressure gradient between the left atrial, pulmonary capillary wedge, or pulmonary artery diastolic pressures and the left ventricular diastolic pressure. Necropsy showed mitral stenosis caused by thickened, fused mitral valve leaflets in 5 dogs and a supramitral ring in another dog. The outcome in affected dogs was poor; 9 of 15 dogs were euthanatized or died by 2 1/2 years of age

    Objective: To determine the safety and efficacy of percutaneous balloon mitral valvuloplasty (PBMV) for patients with mitral stenosis and severe pulmonary hypertension, and to assess the changes in pulmonary systolic pressure during follow-up. Methods: Forty-two patients with rheumatic mitral stenosis and severe pulmonary hypertension (pulmonary systolic pressure > 75 mmHg) underwent PBMV using standard Inoue technique, and the changes in clinical functional status and echo Doppler pulmonary systolic pressure during follow-up were assessed. Results: PBMV was successful in 39 patients. Immediately after the procedure, mitral valve area increased from (0.83 +- 0.12) cm 2 to (1.75 +- 0.11) cm 2 , pulmonary systolic pressure decreased from (85 +- 7) mmHg to (61 +- 13) mmHg (all P < 0.001). Severe mitral regurgitation occurred in 3 patients, one of whom underwent mitral valve replacement. During follow-up (average 6 months), in 39 patients with successful PBMV, the clinical functional status was improved and pulmonary systolic pressure was further decreased despite unchanged mitral valve area. Conclusions: PBMV was safe and effective for patients with mitral stenosis and severe pulmonary hypertension. Clinical functional status was improved and pulmonary systolic pressure was continuously decreased during the short-term follow-up

    ALCAPA syndrome (anomalous origin of the left coronary artery from the pulmonary artery) is a rare disease but lethal with clinical expression from myocardial infarction, congestive heart failure to death during early infancy and unusual survival to adulthood. We report a 73-year-old woman with ALCAPA who presented with exertional dyspnea (NYHA functional class II) over past 2 years. Physical examination revealed soft S, long mid diastolic rumbling murmur and apical pan-systolic murmur. Electrocardiography displayed biatrial enlargement and poor R progression and normal sinus rhythm. Echocardiography established calcified severe mitral stenosis (MS), presence of continuous flow entering the pulmonary trunk, turbulent continuous flow in inter-ventricular septum with left to right shunt in contrast echocardiography and normal systolic function. Coronary angiogram showed absence of left coronary artery (LCA) originating from aorta, dilated and tortuous right coronary artery (RCA) and abundant Rentrop grade 3 intercoronary collateral communicating with LCA originating from pulmonary trunk which was also confirmed on coronary CT angiogram thus establishing diagnosis of ALCAPA. It is exceedingly rare to be associated with severe MS. However, such a long survival in our patient can be explained by the severe pulmonary arterial hypertension which may be contributing to lesser coronary steal.

    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 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

The average mitral valve area of patients was 1.1±0,3 cm2. When patients were divided according to New York Heart Association (NYHA classification ; 16 patients were NYHA 2 (Grup A and 16 patients were NYHA 3 (Grup B. There were not any asymptomatic patients and no patients were NYHA 4. Left atrium diameters, left atrium volume, left atrium fractional area change and left atrium ejection fractions  of patients in these groups were calculated.   Results: The demographic characteristics of patients is shown in table 1. Left atrium ejection fraction (LAEF and left atrium fractional area change (LAFAC that were determined echocardiographycally were significantly lower in patients with mitral stenosis (32 ± 5, 44 ± 3; p<0.001- 25 ± 11, 32 ± 6; p< 0.02.  When patients were divided according to New York Heart Association (NYHA classification ; 16 patients were NYHA 2 (Grup A and 16 patients were NYHA 3 (Grup B. There were not any asymptomatic patients and no patients were NYHA 4. The clinical and echocardiographic data of patients are shown in table 2. Despite of similar mitral valve area and average mitral gradient ,systolic pulmonary artery pressure was found to be higher in symptomatic group. But there was no difference between left atrial functions of the two groups.   Discussion: In this study we have shown that left atrial functions determined echocardiographically  can decline in patients with mitral stenosis but the

    One hundred and twenty-six patients with rheumatic mitral stenosis were studied by M-mode and/or two-dimensional echocardiography. Eighty-nine patients were also submetted to cardiac catheterization and all 126 patients subsequently underwent mitral valve surgery (51 valvulotomy and 75 valve replacement). The mitral valve area measured by two-dimensional echocardiography showed a significant correlation both with hemodynamic (r=0.803, p 2 , respectively; likewise there was non significant difference in pulmonary vascular resistances (3.9 and 3.4 mmHg/l/min/m 2 ) between patients who showed functional improvement after surgery comparison to those who showed no improvement. Finally, coronary arteriography appeared to be necessary, before operation, only in cardiography is able to provide a satisfactory preoperative assessment of patients with mitral stenosis and that therefore these patients need not necessarily to be submitted to cardiac catheterization

    There are different clinical cardiac applications of dual source computed tomography (DSCT). Here, we aimed to compare the DSCT with the transthoracic echocardiography (TTE) for evaluating the Wilkins score and planimetric mitral valve area (MVA) of a rheumatic stenotic mitral valve. We prospectively evaluated mitral valvular structure and function in 31 patients with known mitral stenosis undergoing electrocardiogram-gated, second-generation DSCT, in our heart center for different indications. Mitral valve was evaluated using Wilkins score, and also, the planimetric MVA was assessed. We found a significant difference between MVAs determined by DSCT (average 1.42 ± 0.44 cm2) and MVAs determined by TTE (average 1.35 ± 0.43 cm2 ; difference 0.07 ± 0.16 cm2; P = 0.018). Linear regression analysis revealed a good correlation between the two techniques (r = 0.934; P < 0.0001). The limits of agreement for DSCT and TTE in the Bland-Altman analysis were ±0.31 cm2 . DSCT using TTE as the reference enabled good discrimination between mild and moderate-to-severe stenosis and had an area under the ROC curve of 0.967 (CI 0.912-1.023; P < 0.0001). Wilkins scores obtained by DSCT (7.51 ± 1.17, range 5-10) and TTE (8.16 ± 1.27, range 6-10) had a moderate correlation (r = 0.686; P < 0.0001). We found that planimetric MVA measurements assessed by DSCT were closely correlated with MVA calculations by TTE. The moderate correlation was observed for the Wilkins score. © 2015, Wiley Periodicals, Inc.

    Percutaneous transvenous mitral commissurotomy (PTMC) was performed successfully without complications in 3 patients with severe mitral stenosis and hyperthyroidism. All 3 patients had pliable, noncalcified mitral valves. One patient who had been treated with methimazole for 6 months was still in a hyperthyroid state when she presented with intractable congestive heart failure and was found to have severe mitral stenosis. The heart failure improved immediately after PTMC, but the patient remained in New York Heart Association functional class 2 until a euthyroid state was achieved with I131 therapy. In the other 2 patients, hyperthyroidism was unsuspected at the time of PTMC. Unexpectedly suboptimal symptom improvement led to the diagnosis of hyperthyroidism 1 month after the intervention. In all 3 patients, PTMC resulted in an immediate hemodynamic and clinical improvement. However, complete clinical improvement occurred only when euthyroid state was achieved after antithyroid treatment. The present study suggests that PTMC is a safe and effective intervention modality in patients with coexisting hyperthyroidism and severe mitral stenosis. The procedure may be considered a therapeutic option in patients with hyperthyroidism and severe mitral stenosis.

    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.

    Left atrial enlargement in mitral stenosis predisposes to atrial fibrillation (AF). Analysis of heart rate variability (HRV) prior to the onset of an arrhythmia may show alterations in autonomic balance that are known to predispose to the development of AF. The aim of this study was to determine whether HRV in patients with rheumatic mitral stenosis (MS) is abnormal in comparison to normal controls, and to find the relationship between the left atrial size and HRV in patients with MS in sinus rhythm in AF. A series of 24-hour ambulatory Holter electrocardiogram recordings were obtained for 10 consecutive, newly diagnosed untreated subjects with pure mitral stenosis in sinus rhythm, 10 with mitral stenosis complicated by atrial fibrillation and 10 age-matched normal controls. Digitized records were processed using time domain and power spectral analysis. In patients with mitral stenosis in sinus rhythm, we observed significant decrease of the standard deviation of RR intervals (SDRR), as well as of the root mean square of successive RR interval differences (RMSSD) and Edinburgh index (sNN50), while in patients with AF, the RMSSD and sNN50 were much larger than those in normal. The areas under all spectral bands were markedly increased in patients with AF compared with normal. HRV measures were independent of atrial size in both groups. Decreased HRV in mitral stenosis patients with sinus rhythm suggests increased sympathetic activity in patients prone to atrial fibrillation, while marked increased of HRV in patients with AF may indicate that parasympathetic activity modulates the intrinsic behavior of the atrioventricular node during atrial fibrillation. The evaluation of HRV may be a useful tool for the identification of patients predisposed to AF. (author)

    Full Text Available OBJECTIVE: For a cohort of patients with congenital mitral stenosis (CMS, to determine: patient outcomes, predictors of valve repairability and predictors of durability of valve repair. METHODS: From 1989 and 2002, 23 patients underwent surgical treatment of CMS, excluding those with common atrioventricular canal, and univentricular forms. The median age at operation was 15.5 months (range 2-204, and the median body weight was 11 Kg (range 4.5-51.6. Seventeen patients (73.9% had associated anomalies, including Shone's complex in nine (39.1% and pulmonary hypertension in 14 (60.9%. Mitral stenosis was severe in 14 patients (60.9% and moderate in the remaining (median trans-mitral gradient of 16 mmHg, range 8.5-32. Mitral valve repair was performed in 18 patients (78.3%, and valve replacement in five (21.7%. Repair techniques included papillary muscle splitting (n=10, excision of supravalvular ring (n=9 and commissurotomy (n=8. Twelve patients (52.2% required associated procedures. RESULTS: There were no early and late deaths at a mean follow-up of 58.5 ± 46.7 months (range 1-156. Mean hospital stay was 12.7 ± 8.2 days. There were no significant factors associated with unsuccessful valve repair. Actuarial freedom from reoperation at five years was 67.1% (CI 95%: 56.8% to 77.4%. The mitral valve repair group required reoperation in eight patients (44.4% (two early and six late, as opposed to one (20% in the replacement group. The presence of preoperative pulmonary hypertension was significantly related (p<0.005 to higher reoperation rates. All but two the followed patients are presently in functional class I and the echocardiography has shown less than 2+ mitral stenosis and/or regurgitation. CONCLUSION: Reoperations were the most important cause of morbidity at the medium-term follow-up of CMS. Preoperative pulmonary hypertension may predict the need for reoperation after mitral valve repair, which is the procedure of choice in CMS.

    2009-01-01

    We treated a 61-year-old woman with mitral stenosis caused by pannus formation after Duran ring annuloplasty. Pannus overgrowth on the ring with extension onto both leaflets narrowed the mitral orifice and severely restricted the mobility of the valve leaflets. Mitral valve replacement with a St. Jude Medical mechanical heart valve prosthesis was successfully performed, and the postoperative course was uneventful. Patients undergoing Duran ring annuloplasty should be followed up with the consideration of possible mitral stenosis caused by pannus extension, as the cause for pannus formation remains unclear.

    Full Text Available Background: Severe mitral stenosis is occasionally associated with significant tricuspid regurgitation (TR and this association has an adverse impact on morbidity and mortality in patients undergoing mitral valve intervention. However, the effect of successful mitral balloon valvotomy (MBV on significant TR is not fully elucidated. The aim of this study was to investigate the course of TR after MBV in patients with severe mitral stenosis with TR.Methods: The present study was performed in Tabriz Madani heart center from March 2007 to February 2008. Among 110 patients with mitral stenosis who were candidates of MBV, 68 cases with more than mild TR were selected and the fate of TR after MBV and its predictors were evaluated. Results: Among 68 patients who were enrolled in this study, 58 individuals (85.3% were female with mean age of 36.85± 14.32 years. Before intervention, 48 patients (70.6% had severe TR and 20 (29.4% cases had moderate TR. After intervention, 14 patients suffered from mild TR, 22 from moderate TR and 32 patients from severe TR (P<0.05. There were significant changes in mitral valve area (MVA (from 0.82±0.22 to 1.70±0.21 cm2; P<0.0005 and pulmonary artery systolic pressure (PASP (from 53.00±12.04 to 34.91±11.26 cm2; P<0.0005 and right ventricle dimension (RVD varying from 2.97±0.64 to 2.20±0.58 cm; P<0.0005. This study showed significant relationship between MVA, RVD, and PASP as TR regression determinants. In 6-month follow up no patient needed mitral valve surgery or repeated MBV. There was no procedure related mortality and no death was seen in 6 months follow up in the study group. Significant decrease of symptoms was observed in almost all patients after intervention which persisted during follow up period. Conclusions:Significant number of patients with severe MS and moderate or severe TR showed TR regression following MBV which persisted during 6 months follow up. Severity of MS, PASP and RVD were most important

    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

    Severe calcific mitral valve stenosis can rarely occur concomitantly with obstructive hypertrophic cardiomyopathy. In these patients, surgical decalcification of the stenotic mitral valve followed by mitral valve replacement carries significant operative risk and may result in paravalvular leakage, atrioventricular groove disruption, and excessive bleeding. We report the first 2 cases of obstructive hypertrophic cardiomyopathy with severe calcific mitral valve stenosis successfully treated with concomitant transaortic septal myectomy and bypass of the stenotic mitral valve using a valved left atrium to left ventricular conduit.

    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.

    Objective: To analyze the outcome of mitral valve repair in rheumatic heart disease. Study Design: Retrospective analytical. Place and Duration of Study: Armed forces institute of cardiology/National institute of heart diseases Rawalpindi from Jan 2011 to June 2013. Material and Methods: In this retrospective study of 28 patients (15 females). The mean age was 20.2 +- 11.2 years (range, 11 to 55 years). The cause of mitral regurgitation was rheumatic in all patients, with no congenital myxomatous, infective or ischemic cases. About 68 percent patients were in New York Heart Association (NYHA) functional class III or IV. In all the cases posterior ring annuloplasty was done with flexible C- Shape rings with size ranging from 20 to 26 mm. Repairs included anterior leaflet repair with cusp shortening and resuspension (n=17), posterior leaflet repair with quardranguloplasty and transpositioning (n=6), commissuroplasty (n=2) and mixed anterior posterior leaflet repair (n=3). Results: There was no operative mortality. Follow-up was carried out for 10 months. The trivial mitral regurgitation was found in 3 cases (10.7 percent). Four (14.2 percent) patients required mitral valve replacement due to valve dysfunction. Conclusion: Mitral valve repair in rheumatic patients, with current techniques, can effectively correct functional and hemodynamic abnormalities with satisfactory results. (author)

    Mitral stenosis after mitral repair with using an annuloplasty ring is not common and it is almost always due to pannus formation. Mitral valve replacement was required in most of the previous cases of pannus covering the mitral valve leaflet, which could not be stripped off without damaging the valve leaflets. In two cases, we removed the previous annuloplasty ring and pannus without leaflet injury, and we successfully repaired the mitral valve. During the follow-up of 4 months and 39 months respectively, we observed improvement of the patients' symptoms and good valvular function. Redo mitral repair may be a possible method for treating mitral stenosis due to pannus formation after ring annuloplasty. Copyright © 2010 The Society of Thoracic Surgeons. Published by Elsevier Inc.

    Surgical treatment of mitral stenosis (MS) usually consists of open mitral commissurotomy (MC) or percutaneous balloon MC, which require a cardiopulmonary bypass or transseptal approach, respectively. We describe here the first surgical management of congenital MS in a dog using a less invasive procedure, a surgical closed MC under direct echo guidance. A 5-year-old female Cairn terrier was referred for ascites, weakness, and marked exercise intolerance for 2 months, which was refractory to medical treatment. Diagnosis of severe MS associated with atrial fibrillation (AF) was confirmed by echo-Doppler examination and electrocardiography. Poor response to medical treatment suggested a corrective procedure on the valve was indicated. However, due to the cost and high mortality rate associated with cardiopulmonary bypass, a hybrid MC was recommended. A standard left intercostal thoracotomy was performed and three balloon valvuloplasty catheters of differing diameters were sequentially inserted through the left atrium under direct echo guidance. Transesophageal echocardiography revealed a 62% reduction in the pressure half-time compared to the pre-procedure. Thirteen months after surgery the dog is still doing well with resolution of ascites and a marked improvement of most echo-Doppler variables. Copyright © 2011 Elsevier B.V. All rights reserved.

    Mitral stenosis, the most frequent heart disease in adult, showed relatively characteristic pulmonary findings in plain chest X-ray. In recent years the knowledge of the altered physiology of hemodynamics could offer considerable amount of hemodynamic barrier in plain chest. But the value of several parameters was still controversial. In this study a variety of roentgen signs were related to physiologic data and those were acquired by the cardiac catheterization in total of 67 cases of mitral stenosis. 1. Correlation of DPA/DHT ratio (Diameter of pulmonary arterial segment/ Diameter of hemithorax X 100) to hemodynamic data; The pulmonary arterial segments was dilated by two factors, the one was pulmonary blood flow and the other the blood pressure within it. In mitral stenosis, the cardiac output was decreased to quite uniform level, hence measurement of pulmonary arterial segment might be valuable. The correlation coefficient of DPA/ DHT ratio to hemodynamic data were as follows: 0.54 to mean pulmonary artery pressure, 0.32 to pulmonary capillary wedge pressure, -0.37 to mitral valvular area and 0.07 to pulmonary vascular resistance. No significant difference was noted in between pure mitral stenosis and mitral stenosis associated with other valvular disease. 2. Correlation of diameter of right descending pulmonary artery to hemodynamic data: The measurement was made near the first bifurcation of right descending pulmonary artery at its widest point. Pulmonary vascular pattern was best correlated (r=0.71). Another had rough correlation: 0.05 to mean pulmonary artery pressure, 0.31 to pulmonary capillary wedge pressure, -0.44 to mitral valvular area in correlation coefficient. No pulmonary arterial hypertension was observed in the cases diameter of less than 12 mm, but all except two cases had pulmonary hypertension in which diameter exceeded 16 mm.

    Full Text Available Mitral stenosis is a valvular heart disease, that is the most troublesome during pregnancy and birth process. Plasma volume increases due to sodium and water retention during pregnancy and in the second trimester of pregnancy it reaches the maximum level. In the first trimester of pregnancy, normal cardiac output increases by 30 to 40% and this condition causes significant hemodynamic changes in patients with mitral stenosis. Pulmonary edema occurs rapidly with high left atrial pressure due to increased preload. İt is noted that acute pulmonary edema is the primary cause of maternal mortality in pregnant women with mitral stenosis. Clinical signs are becoming evident, especially after the twelfth week. Despite the best conservative treatment, maternal and infant mortality can be seen.In this case, we present pulmonary edema due to mitral stenosis dianosed following dyspne in a 19 years old pregnant woman at the 29th week of her first pregnancy.

    To determine the clinical and echocardiographic characteristics of contemporary patients with rheumatic mitral regurgitation (MR) at Chris Hani Baragwanath Academic Hospital. This prospective, cross-sectional study included 84 patients with isolated moderate or severe rheumatic MR who underwent clinical and echocardiographic assessment. Mean age of the patients was 44 ± 15.3 years (84% females). Acute rheumatic fever was rare. Hypertension and HIV were present in 52 and 26%, respectively. Echocardiography showed leaflet thickening and calcification, restricted motion and subvalvular disease in 41, 25 and 34%, respectively. Carpentier IIIa leaflet dysfunction occurred in 80% of patients and leaflet prolapse was seen in only 20%. These findings contrast with the previous literature, where patients were younger, they had rheumatic carditis and there were no co-morbidities. Leaflets were pliable, isolated leaflet prolapse was common and commissural fusion was absent. Contemporary patients with rheumatic MR were older, fewer had rheumatic fever and there were more co-morbidities. Echocardiographic features had evolved to greater leaflet thickening, calcification and reduced motion with minimal prolapse. These findings may have important implications for surgical management of this disease.

    The aim of this study was to evaluate the effect of cardiac rhythm on the echocardiographic mitral valve area (MVA) and transmitral gradient calculation in relation to net atrioventricular compliance (Cn). Patients (n=22) with mild or moderate pure rheumatic mitral stenosis (MS) (MVA 1 cm2) and atrial fibrillation (AF) were evaluated. All patients underwent transthoracic electrical DC cardioversion under amiodarone treatment. Nineteen of the 22 patients were successfully converted to sinus rhythm (SR). The patients were evaluated with transthoracic echocardiography before and two to three days after DC cardioversion. In order to deal with variable R-R intervals, the measurements were averaged on five to eight consecutive beats in AF. Cn was calculated with a previously validated equation [Cn (mL/mm Hg)=1.270 x MVA/E-wave downslope]. The Cn difference between AF and SR was calculated as follows: [(AF Cn-SR Cn)/AF Cn] x 100. The percentage gradient (mean or maximal) difference between AF and SR was calculated as follows: [AF gradient (mean or maximal) - SR gradient (mean or maximal)]/[AF gradient (mean or maximal)] x 100. The MVA was lower (MVA planimetric; 1.62±0.29 vs. 1.54±0.27; p=.003, MVA PHT; 1.66±0.30 vs. 1.59±0.26; p=0.01) but transmitral gradient (mean gradient; 6.49±2.51 vs. 8.89±3.52; p=0.001, maximal gradient: 16.94±5.11 vs. 18.57±4.54; p=0.01) and Cn values (5.37±0.77 vs. 6.26±0.64; pgradient difference (mean and maximal) (Cn difference-mean gradient difference; r=0.46; p=0.05; Cn difference-maximal gradient difference; r=0.72; p=0.001). Cardiac rhythm has a significant impact on echocardiographic evaluation of MVA, transmitral gradient, and Cn in patients with MS.

    A female neonate with mitral stenosis due to accessory mitral valve with ventricular septal defect and patent ductus arteriosus is described. She was referred to our hospital because of neonatal asphyxia. Asphyxia was improved by ventilator support, but rapid deterioration of respiration with pulmonary congestion and hemorrhage appeared 8 days after birth. Echocardiography revealed an accessory mitral valve attached to the anterior mitral leaflet with a perimembranous ventricular septal defect and patent ductus arteriosus. Although there were no echocardiographical findings indicating mitral stenosis on admission, the mitral stenosis blood flow patterns were detected by color and pulsed Doppler examination performed on the eighth day after admission. Transaortic resection of accessory mitral valve tissue was performed with patch closure of the ventricular septal defect and ligation of the ductus arteriosus 35 days after birth. After operation, pulmonary congestion and hemorrhage were improved. Postoperative echocardiography showed complete resection of the accessory mitral valve and no mitral insufficiency. We concluded that the combination of the accessory mitral valve and left-to-right shunt due to ventricular septal defect or patent ducturs arteriosus might have led to a critical hemodynamic condition due to relative mitral stenosis in the neonatal period with the decrease in pulmonary vascular resistance.

    Serial radionuclide ventriculography was performed using a newly developed ''real-time'' system, and left ventricular ejection fraction (LVEF), right ventricular ejection fraction (RVEF), stroke volume (SV), and cardiac output (CO) were measured during graded supine exercise in five patients with mitral stenosis (MS), in five patients with chronic obstructive pulmonary disease (COPD) and in five healthy subjects. Simultaneous pulmonary gas exchange analysis permitted determining the anaerobic threshold, which is the point during incremental exercise when lactate begins to accumulate in the blood. LVEF at the anaerobic threshold was not significantly changed in any patient groups and in healthy subjects, but RVEF at the anaerobic threshold was lower in COPD and MS patients as compared with healthy subjects. In MS, SV during exercise was reduced at the anaerobic threshold, but not in COPD or in healthy subjects. In conclusion, reduced working capacity is related to decreased RVEF in both COPD and MS, but the inhibited increase in CO during exercise is also important for the working capacity in MS. (author)

    Full Text Available Aim. To find echocardiographic indicators of heart remodelling that improve estimation of heart failure (HF severity. To evaluate sensitivity of laboratory markers of HF, brain (BNP and atrial (ANP natriuretic peptides, in patients with mitral heart diseases of rheumatic aetiology.Material and methods. 100 patients with rheumatic mitral disease and chronic HF (CHF of I-IV class (NYHA were examined. Echocardiography was performed in all patients with evaluation of the standard indices to define disease severity. Indices of sphericity, myocardial stress of the left ventricle, etc were also evaluated. BNP and ANB levels were assessed by enzyme immunoassay method.Results. CHF severity had the strongest correlations with atrial sizes, left atrial systolic function and level of pulmonary hypertension. Moderate increase of BNP level in severe CHF (III-IV class and its rare increase in mild CHF (I-II class were detected. Significant changes of ANP level were not found. Moderate correlation of BNP level with myocardium mass index, level of pulmonary hypertension and mitral regurgitation was detected.Conclusion. Intensity of heart remodelling in rheumatic mitral diseases is mainly determined by the left atrial area, left atrial systolic function, mitral orifice size, levels of mitral regurgitation and pulmonary hypertension, size and ejection fraction of right ventricle. Normal BNP level does not confirm an absence of CHF or negative prognosis in patients with rheumatic heart disease.

    Objective: To assess long-term results (more than 5-year) after percutaneous balloon mitral valvuloplasty (PBMV) on mitral stenosis (MS) with severe pulmonary hypertension. Methods: Thirty patients after PBMV underwent critical evaluations including echocardiography, chest film and clinical status throughout the follow-up period (6.4 +- 1.4 years). Results: Before and after PBMV and at follow-up, mean mitral valve areas were (1.19 +- 0.32) cm 2 vs (1.99 +- 0.45) cm 2 vs (1.44 +- 0.42) cm 2 respectively (P<0.01 respectively). Restenosis rate was 53.3% at the end of follow-up. There were twenty-eight (93.3%) patients who obtained at least I class (NYHA class) improvement in cardiac function shortly after PBMV. At the end of follow-up, twenty-two (73.3%) patients were still in class I or II without mitral re-operation or repeated valvuloplasty. Conclusions: Long-term follow-up results after PBMV in mitral stenosis with severe pulmonary hypertension was satisfied, and PBMV can be an excellent therapy to improve the clinical status of such patients

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

    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.

    To compare the curative effect of Cox/maze III procedure combined with mitral replacement and that of mitral valve replacement (MVR). Fifty-six patients suffering from rheumatic heart disease with atrial fibrillation (AF) were treated by Cox/maze III procedure combined with MVR (maze group). Another 56 age, sex, and heart function-matched patients with the same diagnosis underwent MVR alone during the same period. Warfarin was administered after operation in both groups. Comparison of operative complication and curative effects was made. The aortic cross-clamp time and cardio pulmonary bypass time (CPB) were longer in maze group than in MVT group (75 +/- 22 min vs 41 +/- 11 min, P Atrial contractility was restored in all patients with sinus rhythm. One year after operation, 98.18% patients' cardiac function changed to grade and 1.82% changed to grade II. In MVR group AF disappeared after operation temporarily for 24 hours in 7 patients and re-appeared, and AF disappeared in one patients for 2 years so far. One year after operation, the cardiac function of 94.6% patients in MVR group changed to grade I, of 3.6% patients to grade II, and of 1.8% patients to grade III. No serious hemorrhage relate d to anticoagulant therapy happened. One patient in MVR group suffered from hemiplegia due to cerebral embolism. The late mortality was 1.8% on maze group amd 3.6% in MVR group. Cox/maze III procedure combined with NVR is safe and effective in treating rheumatic heart disease with AF.

    The heart is the principal organ that circulates blood. In normal conditions it produces four sounds for each cardiac cycle. However, most often only two sounds appear essential: S1 and S2. Two other sounds: S3 and S4, with lower amplitude than S1 or S2, appear occasionally in the cardiac cycle by the effect of disease or age. The presence of abnormal sounds in one cardiac cycle provide valuable information on various diseases. The aortic stenosis (AS), as being a valvular pathology, is characterized by a systolic murmur due to a narrowing of the aortic valve. The mitral stenosis (MS) is characterized by a diastolic murmur due to a reduction in the mitral valve. Early screening of these diseases is necessary; it's done by a simple technique known as: phonocardiography. Analysis of phonocardiograms signals using signal processing techniques can provide for clinicians useful information considered as a platform for significant decisions in their medical diagnosis. In this work two types of diseases were studied: aortic stenosis (AS) and mitral stenosis (MS). Each one presents six different cases. The application of the discrete wavelet transform (DWT) to analyse pathological severity of the (AS and MS was presented. Then, the calculation of various parameters was performed for each patient. This study examines the possibility of using the DWT in the analysis of pathological severity of AS and MS.

    Full Text Available Objective: Our aim is to determine the effect of mitral valvular disease on pregnancy follow up parameters and newborns. Material and Methods: We retrospectively reviewed the pregnant patients those were hospitalized because of mild-moderate mitral valve stenosis (n=16 between January 1998 and January 2011 in our center. Echocardiography was performed with regular intervals and the datas were recorded. Gestational age of delivery, type of delivery, general condition of newborn due to APGAR system were assessed. Values were compared with those of controls without any cardiac disease (n=16. Results: Mean mitral valve area, average mitral gradient and systemic pulmonary artery pressure were established 1.44+0.45 cm2, 5.2+1.5 mmHg ve 23+4.8 mmHg respectively in patients with mitral stenosis. Mean gestational age of delivery was 36.2±1.4 weeks (p=0.001 and mean fetal weight was 2646±431.1 g (p=0.016 in patients with mitral valve stenosis. These values were 38.7±2.12 weeks and 3056±212.13 gram respectively in control group. No significant difference was observed in terms of 1. and 5. APGAR scoring system among two groups. Conclusion: To optimize pregnancy outcomes, accurate diagnosis of the etiology, severity of valve disease and preconception evaluation are the main factors. Obstetrician should be careful in terms of intrauterine growth retardation and preterm delivery during pregnancy in patients with mitral valve stenosis.

    A 50-year-old man presented with acute onset dyspnea following cocaine use. He had severe aortic stenosis (AS), mild mitral regurgitation (MR) due to mitral valve prolapse, and no coronary artery disease on recent coronary angiography. He was in acute heart failure with signs of impending cardiogenic shock. Urgent bedside echocardiography revealed hyperdynamic left ventricular systolic function with acute severe MR from a ruptured chordae tendineae. The acute cocaine-induced spike of his already elevated left ventricular systolic pressure from severe AS likely precipitated chordal rupture of his vulnerable mitral valve. This patient underwent emergent mitral and aortic valve replacements. Although cocaine use has been associated with a myriad of cardiovascular complications, acute MR due to chordal rupture has not, to our knowledge, been previously reported in this setting. Prompt diagnosis with echocardiography and surgical intervention are of paramount importance in the management of acute MR.

    To assess the gender-based differences in the echocardiographic outcomes of patients with mitral stenosis presenting at a tertiary care hospital and the clinical implications of such differences. Methods: A total of 90 echocardiographs of both men and women (aged=15 years) having mitral valve area (MVA) less than 4 cm/sup 2/ were assessed. In addition to MVA, pressure half time and left atrial diameter (LAD) of the patients was also recorded. Other co-existing valvular lesions were also assessed in addition to mitral stenosis. Statistical analysis was done using SPSS-17. Results: A higher prevalence of mitral stenosis (MS) was found in women than men (76.66% vs 24.44%). Men were having more severe mitral stenosis as compared to women (MVA=1.19 cm/sup 2/ vs 1.32 cm/sup 2/). This also resulted in significantly higher left atrial dilatation in males as compared to women (45.09 vs 41.75, p=0.0422). Most of the patients had other coexisting valvular lesions and isolated MS was rare. However, men had a predominance of aortic stenosis along with mitral stenosis (27% vs 4%, p=0.0059) whereas women had a higher prevalence of mitral regurgitation along with mitral stenosis than the men (65% vs 36%, p=0.0258). Conclusion: There were certain significant differences in echocardiographic outcomes of patients based upon their gender. A gender-specific management approach towards the patients with mitral stenosis is essential to have better outcome. (author)

    We aimed to explore the relationship between brain natriuretic peptide (BNP) levels and right ventricular (RV) function in patients with mitral stenosis (MS), and to investigate the hemodynamic parameters that predict reduction of BNP levels after percutaneous mitral valvuloplasty (PMV). Few studies have evaluated BNP in the context of MS, specifically the impact of the RV stroke work (RVSW) on serum BNP levels has not been defined. Thirty patients with symptomatic rheumatic MS in sinus rhythm who were referred for a PMV were enrolled. Right and left heart pressures were obtained before and after valvuloplasty. RVSW index (RVSWI) was calculated by cardiac catheterization. Basal BNP levels were elevated in MS patients and correlated with several hemodynamic parameters including pulmonary pressure, pulmonary vascular resistance index, cardiac index (CI), and RVSWI. In multivariate analysis, CI and RVSWI were independent predictors of raised basal BNP levels. PMV resulted in a significant decrease in the RVSWI with a concurrent increase in CI (2.4 ± 0.43 to 2.9 ± 0.8 L/min/m(2), P = 0.010). Overall, plasma BNP levels significantly decreased from 124 (63/234) to 73 (48/148) pg/ml postvalvuloplasty. Multivariate analysis revealed that the reduction of left atrial (LA) pressure post-PMV was an independent predictor of change in BNP levels. Elevated baseline BNP level in MS patients was independently associated with CI and RVSWI. Plasma BNP levels were reduced after successful PMV, which was associated with the reduction of the LA pressure. © 2013, Wiley Periodicals, Inc.

    Rheumatic mitral valve stenosis (MVS) is a frequent valvulopathy in developing countries. However, industrialized countries have seen the emergence of new etiologies of MVS in recent years, in particular drug-induced and/or toxic valvular regurgitation and stenosis. For this reason, the echocardiographic assessment of MVS and especially the definition of objective diagnostic criteria for severe MVS remains relevant. The objectives are: to determine whether there is a direct causal link between mean transmitral gradient (MTG) and severity of MVS in patients with severe MVS or true severe MVS (primary criterion); to analyze different parameters determining mean transmitral gradient (MTG) (secondary criterion). We conducted a single-center cross-sectional study including all patients with severe or true severe MVS admitted to the Department of Cardiology, University Hospital Ibn Rushd, Casablanca over a period of one year (January 2014-December 2014). We analyzed data from two groups of patients separately: those with a mean transmitral gradientgradient>10mmHg (group 2). 50 patients with severe or true severe MVS have been included in the study. The average age of our patients was 41.7 years with a female predominance (sex ratio 0,25). 64% of patients had severe MVS and 36% of patients had true severe MVS. 52% (26 patients) had MTG gradient> 10mmHg, suggesting no direct correlation between the severity of MVS and MTG (Pearson's correlation coefficient R: -0,137). With regards to dyspnea, 80% of patients of group 1 had stage II NYHA dyspnea (classification system) and 70% of patients of group 2 had stage III NYHA dyspnea (41%) or IV NYHA dyspnea (29%), which means that there was a significant correlation between MTG and the severity of dyspnea (R: 0,586 and p: 0,001). The analytical study of heart rate and the presence of cardiac decompensation compared with mean gradient transmitral showed a significant correlation. Indeed, among patients in group 1, 96% had HR

    Mitral valve repair is perceived to be of limited durability for advanced rheumatic disease in adults. We aim to examine the long-term outcomes of repair for rheumatic disease, identify predictors of durability, and compare with repair for degenerative disease. Rheumatic and degenerative mitral valve repairs in patients aged 40 years or more were prospectively analyzed. The primary outcomes investigated were mortality, freedom from reoperation, and valve failure. Logistic regression analysis was performed to define predictors of poor outcome. Between 1997 and 2011, 253 rheumatic and 148 degenerative mitral valves were repaired. The age of patients in both groups was similar, with a mean of 54.1 ± 8.4 years versus 55.6 ± 7.3 years (P = .49). Freedom from reoperation for rheumatic valves at 5 and 10 years was 98.4%, comparable to 95.3% (P = .12) for degenerative valves. Freedom from valve failure at 5 and 10 years was 91.4% and 81.5% for rheumatic repairs and 82.5% and 75.4% for degenerative repairs, respectively (P = .15). The presence of residual mitral regurgitation greater than 2+ before discharge was the only significant independent predictor of reoperation, whereas residual mitral regurgitation greater than 2+ and leaflet procedures were significant risk factors for valve failure. The durability of rheumatic mitral valve repair in the current era has improved and is comparable to the outstanding durability of repairs for degenerative disease, even in the adult rheumatic population. Modifications of standard repair techniques, adherence to the importance of good leaflet coaptation, and strict quality control with stringent use of intraoperative transesophageal echocardiography have all contributed to the improved long-term results.

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.

    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.

    Rheumatic valve disease, a consequence of acute rheumatic fever, remains endemic in developing countries in the sub-Saharan region where it is the leading cause of heart failure and cardiovascular death, involving predominantly a young population. The involvement of the mitral valve is pathognomonic and mitral surgery has become the lone therapeutic option for the majority of these patients. However, controversies exist on the choice between valve repair or prosthetic valve replacement. Although the advantages of mitral valve repair over prosthetic valve replacement in degenerative mitral disease are well established, this has not been the case for rheumatic lesions, where the use of prosthetic valves, specifically mechanical devices, even in poorly compliant populations remains very common. These patients deserve more accurate evaluation in the choice of the surgical strategy which strongly impacts the post-operative outcomes. This report discusses the factors supporting mitral repair surgery in rheumatic disease, according to the patients' characteristics and the effectiveness of the current repair techniques compared to prosthetic valve replacement in developing countries.

    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.

    The purpose of this study was to evaluate cardiac morphology and function in patients with mitral stenosis (MS). The subjects consisted of 96 patients (23 males and 73 females) with MS who underwent plain and contrast-enhanced CT. Follow-up examinations were performed at least twice in 42 patients, including 18 who were examined before and after surgery. The volume of each cardiac chamber was calculated by Simpson's rule and was divided by body surface area (BSA). The average left atrial (LA) volume was 171[+-]80 cm[sup 3]/m[sup 2] BSA in the 96 MS patients, and 46[+-]10 cm[sup 3]/m[sup 2] BSA in normal control subjects. Atrial fibrillation (Af) was present in 61 patients (64%), and left atrial thrombi were detected in 15 (25%) of them. LA volume increased by 16% in 24 patients without surgery during a mean follow-up period of 4.1 years. The LA tended to enlarge more in the patients with a smaller mitral valve area, a larger LA volume at the first examination, or Af. In 18 patients, after open surgery or percutaneous transvenous mitral commissurotomy, pulmonary CT values decreased significantly as a result of the improvement of pulmonary congestion. LA and RA volume decreased significantly and LV volume increased after surgery. It was concluded that CT was useful for evaluating cardiac function and morphological changes, not only by detecting mitral valve calcification and LA thrombi but also by measuring cardiac volume and pulmonary CT values.

    Congenital coronary anomalies are presented in approximately1% of patient referred for cardiac catheterization. Among the congenital coronary anomalies, a separated anomalous origin of all the coronary arteries from the right sinus of valsalva is very uncommon. We report a rare occurance of simultaneous occurence of mitral stenosis with ectopic origin of left main stem coronary artery from right sinus of Valsalva. PMID:22577434

    The gold-standard treatment of severe mitral regurgitation (MR) due to degenerative disease is valve repair, which is surgically performed with either a leaflet resection or leaflet preservation approach. Recent data suggest that functional mitral stenosis (MS) may occur following valve repair using a leaflet resection strategy, which adversely affects patient prognosis. A randomised comparison of these two approaches to mitral repair on functional MS has not been conducted. This is a prospective, multicentre randomised controlled trial designed to test the hypothesis that leaflet preservation leads to better preservation of mitral valve geometry, and therefore, will be superior to leaflet resection for the primary outcome of functional MS as assessed by 12-month mean mitral valve gradient at peak exercise. Eighty-eight patients with posterior leaflet prolapse will be randomised intraoperatively once deemed by the operating surgeon to feasibly undergo mitral repair using either a leaflet resection or leaflet preservation approach. Secondary end points include comparison of repair strategies with regard to mitral valve orifice area, leaflet coaptation height, 6 min walk test and a composite major adverse event end point consisting of recurrent MR ≥2+, death or hospital readmission for congestive heart failure within 12 months of surgery. Institutional ethics approval has been obtained from all enrolling sites. Overall, there remains clinical equipoise regarding the mitral valve repair strategy that is associated with the least likelihood of functional MS. This trial hopes to introduce high-quality evidence to help surgical decision making in this context.

    Full Text Available Background: Mitral Stenosis refers to narrowing of the mitral valve orifice, resulting in impairment of filling of the left ventricle in diastole. Proximal isovelocity surface area measurement, also known as the flow convergence method, can be used in transthoracic echocardiography to estimate the area of an orifice through which blood flows. Objectives: To compare simple PISA equation, created by combined fixing the angle to 1000 and the Val to 33 cm/s, with mitral valve area measured by pressure half time and planimetry which was taken as reference method. Patients and Methods: A cross sectional prospective study was conducted in multi teaching centers. Total 104 patients were enrolled in this study from which 41 were excluded from the study. Transthoracic echocardiographic examination was used to analyze parameters selected by M-mode, 2D, and pulse doppler. Results: The patients enrolled in this study were with a mean age of 45.4 ± 7.1 years and 23.8% of them within the age group 30-39 years and the remaining 76.2% were >40 years. Female patients were the dominant represented 73.0% while males were 7.0% of the studied group (female: male ratio was 3:1; 61.9% were in sinus rhythm and 38.1% in atrial fibrillation. About 58.7% of the patients had Wilkin’s score less than 8, the mean mitral valve area according to planimetry method was 1.14 ± 0.32 cm2 and it was 1.12 ± 0.28 cm2 by PISA while the mean mitral valve area by pressure half time method was 1.19 ± 0.30 cm2 . The agreement between PISA and planimetry revealed that PISA had good agreement with planimetry in diagnosis of mitral stenosis, (kappa=0.835, P<0.001. On the other hand, there was a fair significant agreement between pressure half time and planimetry. Conclusion: PISA method can effectively predict mitral valve area and severity of mitral stenosis by the equation: mitral valve area = 115 × r2 /Vmax, provided that aliasing velocity is fixed at 33 cm/s, with the advantage of

    The present study was aimed to compare the left atrial and left ventricular diastolic functions amongst the rheumatic and degenerative mitral valve disease patients in atrial fibrillation who reverted to normal sinus rhythm following Cox-maze procedure. We prospectively investigated the left atrial and left ventricular function with Doppler echocardiography, by dividing into the rheumatic (N = 105) and the degenerative group (N = 47). Over the follow-up period (mean: 4.4 ± 1.2 years in the rheumatic group, 4.8 ± 1.3 years in the degenerative group), the rheumatic group showed statistically significant decrease in A' velocity and E' velocity, on contrary to degenerative group (A' velocity: mean decrease of 0.43 ± 0.13 cm/s in the rheumatic group, mean increase of 0.57 ± 0.11 cm/s in the degenerative group, p = 0.029, E' velocity: mean decrease of 0.23 ± 0.17 cm/s in the rheumatic group, mean increase of 0.21 ± 0.15 cm/s in the degenerative group, p = 0.031). In addition, the rheumatic group showed statistically significant increase in E/E' ratio than the degenerative group (mean increase of 4.49 ± 1.98 in the rheumatic group, mean increase of 1.74 ± 1.52 in the degenerative group, p = 0.047). Despite successful sinus rhythm restoration, the progressive loss of LA function as well as LV diastolic function is more prominent in the rheumatic group than the degenerative group. Therefore, differentiated strategies for postoperative surveillance are needed according to the pathology of mitral valve disease.

    Full Text Available Background and Objectives: Acute Myocardial Infarction is a rare complication of Mitral Stenosis, which in rare cases occurs following the use of oral contraceptive pills.Case Report: A 28-year-old woman was admitted to emergency ward with complaint of severe chest pain typical of is chemia. Electrocardiogram showed ST segment elevation in leads II, III, avf, and ST depression in anterior leads. Also, Troponin I level elevated to 16µg/l. Diagnosis of MI of the inferior and lateral walls was established. The patient reported a history of breathlessness after physical activity over the last 2 years, and was aware of her mitral disease. Also, the patient stated that she had been taking oral contraceptive pills over the past 3 months. Transthorasic echocardiography showed severe mitral stenosis (mitral valve area<1cm, and severe hypokinesia of inferior and laterel walls. Coronary arteries were normal in cardiac angiography. It seemed that acute MI in this patient with valvular heart disease, history of OCP use, and normal angiogram was due to thromboembolism from left atrial thrombus.

    Mitral stenosis (MS) is a common cause of atrial fibrillation (AF). Oxidative stress and inflammation factors were shown to be involved in atrial remodeling. The study aim was to compare the oxidative parameters and prolidase activity in severe MS patients with and without AF. The study population was comprised of 33 patients with MS and sinus rhythm (group I), 27 patients with MS and AF (group II), and 25 healthy controls (group III). Plasma prolidase activity, total antioxidant capacity (TAC), total oxidative status (TOS), and oxidative stress index (OSI) were determined. Additionally, we measured tissue TOS and TAC in patients with mitral valve replacement. TAC and OSI were higher, but TOS and prolidase were lower in patients with MS than control (all p 0.05). Tissue TAC was significantly lower in group II than group I (0.015 +/- 0.01 vs. 0.026 +/- 0.01 mmol Trolox equiv/L, p = 0.014), tissue TOS was similar between groups I and II (0.24 +/- 0.06 vs. 0.22 +/- 0.05 mmol Trolox equiv/L, p = 0.161). Presence of AF was correlated with systolic blood pressure, left atrial diameter, plasma TAC, tissue TAC, plasma TOS, plasma OSI, and plasma prolidase activity. Tissue TAC level (beta = -0.435, p = 0.006) and left atrial diameter (beta = 0.460, p = 0.003) were independently related with presence of AF in patients with MS. This study suggested that the presence of AF in patients with severe MS may be associated with the plasma prolidase activity, tissue and plasma oxidative parameters.

    1992-11-15

    We performed radionuclide ventriculography before and within 1 week after percutaneous mirtal valvuloplasty (PMV) to evaluate left ventricular (LV) function in 20 patients (2 meals and 17 females, mean age of 38 {+-} 10 years) who were pure mitral stenosis before PMV and less than grade 1 mirtal regurgitation developed after PMV. 9 out of 20 patients had atrial fibrillation and 3 patients developed a small left-to-right shunt (Qp/Qs < 1.5) after PMV. PMV using double-balloon technique resulted in a increase in mitral valve area (0.9 {+-} 0.3 to 2.1 {+-} 0.8cm{sup 2}, {rho} < 0.001) and in rest cardiac output (4.2 {+-} 1.0 to 4.8 {+-} 1.4 L/min, {rho} < 0.005). And also a decrease in mean mitral gradient (16.2 {+-} 7.0 to 5.2 {+-} 3.0 mmHg, {rho} < 0.001) was noted. Comparisons of LV function by supine bicycle exercise radionuclide ventriculography before and after PMV showed no significant changes in rest LV ejection fraction (LVEF, 55.2 {+-} 9.7 to 56.1 {+-} 11.0%, {rho} > 0.05), maximal exercise LVEF (60.9 {+-} 10.3 to 59.3 {+-} 11.1%, {rho} > 0.05), peak ejection rate (2.02 {+-} 0.58 to 2.15 {+-} 0.60 EDV/ses, {rho} > 0.05), and peak filling rate (1.04 {+-} 0.55 to 1.52 {+-} 0.49 EDV/ses, {rho} > 0.05). However, LV end diastolic volume (LVEDV, -29.3 {+-} 19.0 to +3.3 {+-} 32.9%, {rho} < 0.001), stroke volume (SV,-22.0 {+-} 22.0 to +11.2 {+-} 40.0%, {rho} < 0.001), and cardiac output (CO, 64.6 {+-} 54.0 to 100.4 {+-} 69.7%, {rho} < 0.05) with exercise compared to resting values were significantly increased. We conclude that PMV resulted in a significant increase in LVEDV, SV, and CO with exercise, but decreased LV systolic performance and no improvement in diastolic filling.

    Objective: To approach the cause and treatment of complication during and immediately after percutaneous balloon mitral valvuloplasty. Methods: One thousand three hundred and eleven patients with mitral stenosis were treated by percutaneous transseptal balloon mitral valvuloplasty. Among them, 42 patients with complications were retrospectively analyzed. Results: The overall complications rate was 3.2% (42/1311) including atrial fibrillation 0.8% (10/1311), acute pericardial tamponade 0.31% (4/1311), severe mitral insufficiency 0.46% (6/1311), femoral arterial venous fistula 0.69% (9/1311), acute pulmonary edema and iatrogenic atrial septal defect 0.23% (3/1311), respectively. Coronary air embolism, arterial thrombosis and transient cerebrovascular accident was 0.15% (2/1311) for every other one. Balloon rupture was 0.08%(1/1311). Conclusions: The complications of percutaneous balloon mitral valvuloplasty rarely occur. It is a safe and efficient nonsurgical method for treating rheumatic mitral stenosis

    Full Text Available Accurate measurement of Mitral Valve Area (MVA is essential to determining the Mitral Stenosis (MS severity and to achieving the best management strategies for this disease. The goal of the present study is to compare mitral valve area (MVA measurement by Continuity Equation (CE and Pressure Half-Time (PHT methods with that of 2D-Planimetry (PL in patients with moderate to severe mitral stenosis (MS. This comparison also was performed in subgroups of patients with significant Aortic Insufficiency (AI, Mitral Regurgitation (MR and Atrial Fibrillation (AF. We studied 70 patients with moderate to severe MS who were referred to echocardiography clinic. MVA was determined by PL, CE and PHT methods. The agreement and correlations between MVA’s obtained from various methods were determined by kappa index, Bland-Altman analysis, and linear regression analysis. The mean values for MVA calculated by CE was 0.81 cm (±0.27 and showed good correlation with those calculated by PL (0.95 cm, ±0.26 in whole population (r=0.771, P<0.001 and MR subgroup (r=0.763, P<0.001 and normal sinus rhythm and normal valve subgroups (r=0.858, P<0.001 and r=0.867, P<0.001, respectively. But CE methods didn’t show any correlation in AF and AI subgroups. MVA measured by PHT had a good correlation with that measured by PL in whole population (r=0.770, P<0.001 and also in NSR (r=0.814, P<0.001 and normal valve subgroup (r=0.781, P<0.001. Subgroup with significant AI and those with significant MR showed moderate correlation (r=0.625, P=0.017 and r=0.595, P=0.041, respectively. Bland Altman Analysis showed that CE would estimate MVA smaller in comparison with PL in the whole population and all subgroups and PHT would estimate MVA larger in comparison with PL in the whole population and all subgroups. The mean bias for CE and PHT are 0.14 cm and -0.06 cm respectively. In patients with moderate to severe mitral stenosis, in the absence of concomitant AF, AI or MR, the accuracy

    Full Text Available Rasopathy syndromes are a class of phenotypically similar, but genetically distinct multiple anomaly syndromes caused by germ line mutations in genes that encode protein components of the Ras/mitogen activated protein kinase (MAPK pathway. Noonan syndrome, cardiofaciocutaneous syndrome and Costello syndrome are part of this group of developmental syndromes and have similar cardiac abnormalities. A 19-year-old male presented with complaints of exertional breathlessness class I for 6 months. Clinical examination revealed characteristic facial features, skeletal abnormalities, growth and neurocognitive problems reported in patients with Noonan syndrome. There was evidence of severe pulmonary hypertension. Trans-thoracic echocardiography revealed right atrial and right ventricular enlargement, severe pulmonary hypertension, no intra cardiac shunt, prolapse of anterior mitral leaflet with mild mitral regurgitation. CT pulmonary angiogram revealed bilateral branch pulmonary artery stenosis. A final diagnosis of Noonan syndrome was made.

    The purpose of this study is to investigate the regional pulmonary function in mitral stenosis using Xenon-133 before and after surgical treatment. Twenty-seven patients with mitral stenosis have been studied. There were four types of distribution of pulmonary perfusion. According to the increase of pulmonary capillary wedge pressure, the distribution of pulmonary perfusion showed a vertical distribution different from that of normal man, as well known according to the many past reports. But Type IV(PCWP > 30mmHg) showed the distribution uniform throughout the lung. The patients with Type IV had severe pulmonary vascular resistance and abnormal distribution of ventilation. They showed decreased %VC, SaO 2 and increased FRV in the tests of total lung functions. Postoperatively, the distribution of pulmonary perfusion in Type II and Type III returned to normal after 6 - 12 months of surgical treatment, but in the Type IV never returned to normal even after 12 months of surgical treatment. The hemodynamic data in the Type IV after 3 - 6 months of surgical treatment showed the moderate pulmonary hypertension and pulmonary vascular resistance. In total lung function tests, %VC, SaO 2 and FRV were recognized the improvement after surgical treatment, but they retained under normal range even after 12 months of sutgical treatment. The abnormal distribution of ventilation improved to normal distribution after 12 months of surgical treatment. The regional pulmonary function test using Xenon-133 is very beneficial to estimate the severity of mitral stenosis and to expect the effects of surgical treatment on the pulmonary circulation and ventilation.

    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.

    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.

    Objective: To evaluate the effect of intra-operative single intra venous dose of amiodarone on post operative cardiac arrhythmias in patients undergoing valvular heart surgery. Study Design: Randomized controlled trials. Place and Duration of surgery: This study was performed at Armed forces Institute of Cardiology Rawalpindi from Jan 01, 2011 to Dec 31, 2011. Patients and Methods: In this study 80 patients with rheumatic valvular heart disease and undergoing elective mitral valve replacement were randomly divided into two groups. Group I, n = 40 (Amiodarone group) was given single intravenous dose of amiodarone (5 mg/kg in 100 ml of saline over 30 min) before sternotomy incision. Group II, n = 40(control / placebo group) was given 100 ml of saline over 30 min. Result: In the amiodarone group, after removal of aortic cross clamp 75% patients had sinus rhythm compared to 47.5% in control group. p=0.045. Similarly 15% had AF, 5% JR and 5% VT/VF in amiodarone group in contrast to 32.5% with AF, 12.5% JR and 7.5% Vt/VF in control group. (p=0.045). Response to cardioversion was positive in 75% of the patients requiring shocks in amiodarone group as against 43.75% in the control group. (p=0.044). Conclusion: A single intravenous bolus dose of amiodarone is effective in decreasing the incidence of cardiac arrhythmias after mitral valve replacement in patients with rheumatic MVD. (author)

    While rheumatic heart disease (RHD) is a treatable disease nearly eradicated in the United States, it remains the most common form of acquired heart disease in the developing world. This study used echocardiographic screening to determine the prevalence of RHD in children in American Samoa. Screening took place at a subset of local schools. Private schools were recruited and public schools underwent cluster randomization based on population density. We collected survey information and performed a limited physical examination and echocardiogram using the World Heart Federation protocol for consented school children aged 5-18 years old. Of 2200 students from two private high schools and two public primary schools, 1058 subjects consented and were screened. Overall, 133 (12.9%) children were identified as having either definite (3.5%) or borderline (9.4%) RHD. Of the patients with definitive RHD, 28 subjects had abnormal mitral valves with pathologic regurgitation, three mitral stenosis, three abnormal aortic valves with pathologic regurgitation, and seven borderline mitral and aortic valve disease. Of the subjects with borderline disease, 77 had pathologic mitral regurgitation, 12 pathologic aortic regurgitation, and 7 at least two features of mitral valve disease without pathologic regurgitation or stenosis. Rheumatic heart disease remains a major cause of morbidity and mortality worldwide. The prevalence of RHD in American Samoa (12.9%) is to date the highest reported in the world literature. Echocardiographic screening of school children is feasible, while reliance on murmur and Jones criteria is not helpful in identifying children with RHD.

    Serial radionuclide ventriculography was performed using a newly developed ''real-time'' system, and left ventricular ejection fraction (LVEF), right ventricular ejection fraction (RVEF), stroke volume (SV), and cardiac output (CO) were measured during graded supine exercise in five patients with mitral stenosis (MS), in five patients with chronic obstructive pulmonary disease (COPD) and in five healthy subjects. Simultaneous pulmonary gas exchange analysis permitted determining the anaerobic threshold, which is the point during incremental exercise when lactate begins to accumulate in the blood. LVEF at the anaerobic threshold was not significantly changed in any patient groups and in healthy subjects, but RVEF at the anaerobic threshold was lower in COPD and MS patients as compared with healthy subjects. In MS, SV during exercise was reduced at the anaerobic threshold, but not in COPD or in healthy subjects. In conclusion, reduced working capacity is related to decreased RVEF in both COPD and MS, but the inhibited increase in CO during exercise is also important for the working capacity in MS.

    Introduction: Patients with mitral stenosis (MS) having atrial fibrillation (AF) are more prone to develop left atrial (LA) thrombus. Systemic embolism, related to LA thrombus is a well-known risk of Percutaneous Mitral Balloon Valvotomy (PMBV) of the mitral valve. Therefore presence of LA thrombus is a contraindication to PMBV. Objective: Objective of this study was to detect the frequency of LA thrombus by transesophageal echocardiography (TEE) in patients of tight MS in whom transthoracic echocardiography (TTE) could not detect any LA thrombus. Patients and Methods: In this cross sectional study, we took 100 indoor patients with tight MS on non-probability consecutive sampling. Data was collected after meeting inclusion criteria. Patients were taken in this study after acquiring written informed consent. Symptoms were inquired from all patients and functional status was assessed by New York Heart Association class. Unstable patients were medically managed before the procedure. TEE was done on the same day before undergoing PMBV to look for clot in LA. Results: The mean age of the patients was 32.20 years and SD was 11.3 years. There were 36(36%) male patients and 64(64%) female patients. LA thrombus was present in 40% of patients on TEE out of which 19 were male patients (52.77%) and 21 were female patients (32.81%). Conclusion: Patients with mitral stenosis having AF are more prone to develop LA thrombus. In this study, the frequency of LA thrombus was 40% recorded, which is high. Due to the potential risk of embolization, it is strongly recommended to perform TEE in patients with normal TTE study before undergoing PMBV. The presence of a LA thrombus should be considered a contraindication to the PMBV of the mitral valve. (author)

    Objective: To examine the prevalence, age, sex and topographical distribution of the rheumatic heart diseases and its morphology. Design: A cross sectional descriptive study. Place and Duration of Study: Pathology Department, Army Medical College, Rawalpindi between 1981-1990. Patients and Methods: Five hundred and twenty six surgically excised cardiac valves and biopsies were studied in the laboratory in the light of clinical data. Results: Carditis constituted 87.4 % of the cardiac valvular disease with 23.5% active and 71% healed rheumatic lesions. About 5.5% had morphological appearances consistent with RHD. The lesions affected mitral valves (37.0%), aortic valve (22.1%), mitral and aortic valves together (21.0%) and atrial appendages (19.0%). Presentation was mostly as mitral stenosis either isolated (49.2% ) or combined (31.0%), aortic stenosis (11.7% ) and aortic incompetence with regurgitation (7.3%). Conclusion: Rheumatic carditis constitutes a significant proportion of cardiac valvular disease and affects comparatively younger age, with slight male preponderance and primarily affects mitral valve.

    Secondary mitral regurgitation (SMR) is generally reduced after isolated aortic valve replacement (AVR), but there is important interindividual variability in the magnitude of this reduction. Prosthesis-patient mismatch (PPM) may hinder normalization of left ventricular geometry and pressure overload following AVR, therefore we aimed to investigate the relationship between PPM and regression of SMR following AVR for aortic valve stenosis. A total of 419 patients with AS who underwent isolated AVR at 2 institutions and presenting moderate SMR (mitral regurgitant volume 30 to 45 mL/beat) not considered for surgical correction were included in this study. Clinical and echocardiographic follow-up were completed at a median follow-up time of 37 months. PPM was defined as an indexed effective orifice area ≤0.85 cm(2)/m(2) and was found in 170/419 patients (40.6%). There were no significant differences in baseline and operative characteristics between patients with or without PPM. Patients with PPM had less regression of SMR following AVR compared with those with no PPM (change in mitral regurgitant volume: -11±4 versus -17±5 mL, respectively; Pregression model, which showed indexed effective orifice area (Pregression of SMR following AVR. This unfavorable effect was associated with worse functional capacity. These findings emphasize the importance of operative strategies aiming to prevent PPM in patients with aortic valve stenosis and concomitant SMR.

    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. PMID:23703332

    Full Text Available Balloon mitral valvotomy (BMV performed by the conventional transfemoral approach can be difficult or even impossible in the presence of structural impediments such as severe kyphoscoliosis, gross cardiac anatomic distortion and inferior vena caval anomalies. A 25-year-old woman with severe thoracolumbar kyphoscoliosis due to poliomyelitis presented with symptomatic rheumatic mitral valve stenosis. After the failure of transfemoral BMV, the procedure was attempted from the right jugular access, using a modified septal puncture technique. The left atrium was entered from the jugular access and the mitral valve was crossed and dilated successfully using over the wire balloon technique. Transjugular BMV is an effective alternative in patients with kyphoscoliotic spine that preclude transfemoral approach. The detailed technique used for the procedure, its advantages as well as the other percutaneous treatment options are also discussed.

    Annuloplasty bands and rings are widely used for repairing functional tricuspid regurgitation (FTR). However, the question regarding which is the ideal annuloplasty device remains unclear. The aim of this study was to compare the efficacy and mid-term durability of tricuspid ring annuloplasty for FTR secondary to rheumatic mitral valve disease using flexible Cosgrove-Edwards band and the rigid Edwards MC3 ring (Edwards Lifesciences, LLC, Irvine, CA, USA). We retrospectively collected the clinical data of those who underwent mitral valve replacement (MVR) in concomitant with tricuspid ring annuloplasty from 2009 to 2013. The flexible band was used in 46 patients (flexible group), and the 3D rigid ring was used in 60 patients (rigid group). Echocardiographic evaluation of tricuspid function was performed preoperatively and postoperatively. The grade of TR was significantly improved compared to preoperative values in two groups. There was no significant difference regarding postoperative TR grade between the two groups at 1 week and 2-3 months but there was statistical significant difference at postoperative 6-12 months, and 2-3 years. During the follow up period, 25 of 46 patients (54.3%) in flexible group and 22 of 60 patients (30.3%) in rigid group developed recurrent TR. Freedom from recurrent TR in flexible group is significant lower than rigid group in each postoperative follow up period. These findings suggest that 3D rigid ring annuloplasty might be more effective for tricuspid ring annuloplasty in FTR in mid-term postoperative periods when compared to flexible band.

    Doppler-driven net atrioventricular compliance (C n ), which represents left atrial (LA) compliance, is an important determinant of pulmonary hypertension in mitral stenosis (MS). We hypothesized that decreases in C n during early-stage exercise underlie exercise intolerance in patients with MS. Thirty-three asymptomatic patients with significant MS (valve area 1.24 ± 0.16 cm 2 ) underwent resting and bicycle exercise echocardiography. LA compliance and conventional parameters were assessed at each workload. The patients were classified into two groups based on whether they developed dyspnea during exercise: an exercise-intolerance group (n = 22) and an exercise-tolerance group (n = 11). Moreover, "50 W" was defined as an early exercise stage. Although the groups had similar resting characteristics, there were striking differences in their echocardiographic parameters from the early stages of exercise. The relative C n decrease at 50 W (expressed as a percentage of the resting C n ) was significantly greater in the exercise-intolerance group (70.3 ± 15.4% vs 49.7 ± 9.7%, P intolerance group (P = .0005). Furthermore, differences in the trends in this parameter were observed between the two groups (P intolerance (adjusted OR 1.105, 95% CI 1.030-1.184) after adjustment for other conventional parameters. Decreases in C n during early-stage exercise are an important mechanism underlying exercise intolerance in MS. © 2017, Wiley Periodicals, Inc.

  16. Primary Mitral Valve Regurgitation Outcome in Patients With Severe Aortic Stenosis 1 Year After Transcatheter Aortic Valve Implantation: Echocardiographic Evaluation

    Directory of Open Access Journals (Sweden)

    Thiago Marinho Florentino

    Full Text Available Abstract Background: 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. Objective: To assess the outcome of primary MR in patients submitted to TAVI and to identify associated factors. Methods: 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. Results: 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 < 0.001, while 5 (7.5% showed worsening. Of those with moderate/severe MR, 8 (33.3% maintained the same grade and 16 (66.7% improved it (p = 0.076. Patients with moderate/severe MR who improved MR grade had lower EuroSCORE II (p = 0.023 and STS morbidity (p = 0.027 scores, as compared to those who maintained the MR grade. Conclusion: MR grades change after TAVI. This study suggests a trend towards improvement in moderate/severe MR after TAVI, which was associated with lower preoperative risk scores.

    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.

    A 43-year-old woman, with a remote history of rheumatic mitral stenosis and a St. Jude prosthetic mitral valve replacement, presented with shortness of breath and palpitations, shortly after a long flight. On admission, atrial fibrillation with a rapid ventricular response was noted in the setting of a long history of noncompliance with her anticoagulation. Transesophageal echocardiography (TEE) demonstrated multiple laminated thrombi in the left atrial appendage. Live three-dimensional (3D) TEE confirmed this diagnosis and demonstrated an immobile posterior leaflet of the mitral prosthesis, which had direct implications in her management. She successfully underwent surgery for mitral valve replacement, left atrial appendage ligation, and a Maze procedure on the following day. The multiple thrombi within the atrial appendage were confirmed intraoperatively and pannus formation was determined to be the etiology of the leaflet immobility. © 2011, Wiley Periodicals, Inc.

    To evaluate the effect of percutaneous transvenous mitral commissurotomy (PTMC), equilibrium radionuclide angiocardiography was performed in eight patients with mitral stenosis who had atrial fibrillation. Accurate cardiac function in patients with atrial fibrillation is difficult to assess, since the wide fluctation of cardiac cycle makes the ventricular hemodynamics variable. A new processing algorhythm was devised to make multiple gated images discriminated from a heart rate distribution histogram. We obtained about 1,000 beats data by list mode acquisition, and processed a heart rate distribution histogram. The data in the area {+-}5% of the most frequent heart rate were converted into frame mode and a representative time activity curve was derived. Mitral valve area calculated by echocardiography increased from 1.3{+-}0.5 to 2.0{+-}0.6 (cm{sup 2}) significantly (p<0.01). The mean transmitral pressure gradient measured by catheterization decreased from 12.4{+-}5.9 to 4.9{+-}3.7 (mmHg) significantly (p<0.01) and the clinical symptoms improved in all patients. The change in left ventricular ejection fraction from 43{+-}9 to 48{+-}13 (%) was not statistically significant, but peak filling rate (PFR) derived from the time activity curve increased from 1.5{+-}0.3 to 2.0{+-}0.4 (EDV/sec) significantly (p<0.01). Thus PFR is a noninvasive parameter that can evaluate the effect of PTMC. (author).

    Valvular heart disease is a leading cause of cardiovascular mortality, especially in China. More than a half of valvular heart diseases are caused by acute rheumatic fever. microRNA is involved in many physiological and pathological processes. However, the miRNA profile of the rheumatic valvular heart disease is unknown. This research is to discuss microRNAs and their target gene pathways involved in rheumatic heart valve disease. Serum miRNA from one healthy individual and four rheumatic heart disease patients were sequenced. Specific differentially expressed miRNAs were quantified by Q-PCR in 40 patients, with 20 low-to-moderate rheumatic mitral valve stenosis patients and 20 severe mitral valve stenosis patients. The target relationship between certain miRNA and predicted target genes were analysis by Luciferase reporter assay. The IL-1β and IL1R1 expression levels were analyzed by immunohistochemistry and western blot in the mitral valve from surgery of mitral valve replacement. The results showed that 13 and 91 miRNAs were commonly upregulated or downregulated in all four patients. Nine miRNAs, 1 upregulated and 8 downregulated, that had a similar fold change in all 4 patients were selected for quantitative PCR verification. The results showed similar results from miRNA sequencing. Within these 9 tested miRNAs, hsa-miR-205-3p and hsa-miR-3909 showed a low degree of dispersion between the members of each group. Hsa miR-205-3p and hsa-miR-3909 were predicted to target the 3'UTR of IL-1β and IL1R1 respectively. This was verified by luciferase reporter assays. Immunohistochemistry and Western blot results showed that the mitral valve from rheumatic valve heart disease showed higher levels of IL- 1β and IL1R1 expression compared with congenital heart valve disease. This suggested a difference between rheumatic heart valve disease and other types of heart valve diseases, with more inflammatory responses in the former. In the present study, by next generation

    Background: Clinical profile of acute rheumatic fever and rheumatic recurrence seems to have changed in countries where rheumatic fever is still endemic. The objectives of this study were to compare clinical profile and outcome of patients suffering initial and recurrent episodes of acute rheumatic fever in children. Methods: This prospective study was conducted in two tertiary care hospitals from January to June 2011. The diagnosis was based on the modified Jones criteria. Sixty children were included in the study, 15 having first episode of rheumatic fever and 45 with rheumatic recurrence. The severity of carditis was assessed by Clinical and echocardiography means. Results: Carditis was the commonest presentation in both first (80 percentage) and recurrent attacks (100 percentage). Arthritis was seen in 60 percentage of children with first episode and in 26.7 percentage with recurrence. The frequency of subcutaneous nodules, invariably associated with carditis, was very high (33.3 percentage in the first and 48.3 percentage in recurrent episodes). Carditis was generally mild during first episode (53.3 percentage) and severe with rheumatic recurrence (55.6 percentage). There was no death in either group. One patient with severe mitral regurgitation and rheumatic recurrence underwent mitral valve repair for intractable heart failure. Conclusion: Clinical profile of rheumatic recurrence and acute rheumatic fever has changed. Rheumatic recurrence is associated with severe carditis. Carditis is more common than arthritis even in the first attack. Sub-cutaneous nodules are a frequent finding invariably associated with carditis. (author)

    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.

    We investigated whether patients with rheumatic and degenerative heart valve disease (HVD) differed with regard to plasma and tissue oxidative stress index (OSI). The study included 56 patients who underwent valve replacement due to rheumatic (n=32; 15 males; mean age 47+/-10 years) and degenerative (n=24; 13 males; mean age 55+/-12 years) HVD. Plasma and tissue total oxidative status (TOS) and total antioxidative capacity (TAC) levels were measured and OSI was calculated. Patients with degenerative HVD had significantly higher age, increased interventricular septum thickness, and higher frequency of aortic stenosis, whereas the incidence of mitral stenosis was higher in patients with rheumatic HVD (p0.05). Tissue TAC was significantly lower in patients with rheumatic HVD (p=0.027), whereas tissue TOS and OSI were similar between the two HVD groups (p>0.05). In bivariate analysis, plasma OSI did not show any correlation with clinical, laboratory, and echocardiographic variables (p>0.05). Our data show that plasma and tissue OSI levels are similar in patients with rheumatic and degenerative HVD.

    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.)

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.

    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.

    This study sought to examine the prevalence of mitral stenosis (MS) and its impact on in-hospital and 1-year clinical outcomes among patients undergoing transcatheter aortic valve replacement (TAVR). Patients with coexisting severe aortic stenosis and MS are increasingly being considered for TAVR. The study cohort included 44,755 patients (age ≥18 years) who underwent TAVR during November 1, 2011, to September 30, 2015, and were registered in Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapies (TVT) Registry. One-year outcomes were assessed by linking TVT registry data of this cohort to patient-specific Centers for Medicare & Medicaid Services administrative claims data (n = 31,453). The primary outcome was the composite of death, stroke, heart failure-related hospitalization, and mitral valve intervention at 1 year. MS was present in 11.6% of cohort (mean age, 82 years; 52% males), being severe in 2.7%. Severe MS was associated with higher in-hospital mortality rates (5.6% vs. 3.9% for nonsevere MS and 4.1% for no MS; p = 0.02). In contrast to those without MS, severe MS group had significantly higher risk for the primary outcome, mortality (1 year), and heart failure-related hospitalization (1 year) (adjusted hazard ratio: 1.2 [95% confidence interval (CI): 1.1 to 1.4], 1.2 [95% CI: 1.0 to 1.4], and 1.3 [95% CI: 1.1 to 1.5], respectively; p < 0.05 for all). Approximately one-tenth of patients undergoing TAVR have concomitant MS. Severe MS is an independent predictor of 1-year adverse clinical outcomes following TAVR. The higher risk for long-term adverse events must be considered when evaluating patients with combined aortic stenosis and MS for TAVR. Copyright © 2018 American College of Cardiology Foundation.

    2016-06-01

    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.

    Rheumatic heart disease (RHD) remains a major public health concern in developing countries, and routine screening has the potential to improve outcomes. Standard portable echocardiography (STAND) is far more sensitive than auscultation for the detection of RHD but remains cost-prohibitive in resource-limited settings. Handheld echocardiography (HAND) is a lower-cost alternative. The purpose of this study was to assess the incremental value of HAND over auscultation to identify RHD. RHD screening was completed for schoolchildren in Gulu, Uganda, by using STAND performed by experienced echocardiographers. Any child with mitral or aortic regurgitation or stenosis plus a randomly selected group of children with normal STAND findings underwent HAND and auscultation. STAND and HAND studies were interpreted by 6 experienced cardiologists using the 2012 World Heart Federation criteria. Sensitivity and specificity of HAND and auscultation for the detection of RHD and pathologic mitral or aortic regurgitation were calculated by using STAND as the gold standard. Of 4773 children who underwent screening with STAND, a subgroup of 1317 children underwent HAND and auscultation. Auscultation had uniformly poor sensitivity for the detection of RHD or valve disease. Sensitivity was significantly improved by using HAND compared with auscultation for the detection of definite RHD (97.8% vs 22.2%), borderline or definite RHD (78.4% vs 16.4%), and pathologic aortic insufficiency (81.8% vs 13.6%). Auscultation alone is a poor screening test for RHD. HAND significantly improves detection of RHD and may be a cost-effective screening strategy for RHD in resource-limited settings.

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.

    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.

    Full Text Available Abstract Introduction: Current guidelines state that patients with severe mitral regurgitation should be treated in reference centers with a high reparability rate, low mortality rate, and durable results. Objective: To analyze our global experience with the treatment of organic mitral regurgitation from various etiologies operated in a single center. Methods: We evaluated all surgically treated patients with organic mitral regurgitation from 2004-2017. Patients were evaluated clinically and by echocardiography every year. We determined early and late survival rates, valve related events and freedom from recurrent mitral regurgitation and tricuspid regurgitation. Valve failure was defined as any mitral regurgitation ≥ moderate degree or the need for reoperation for any reason. Results: Out of 133 patients with organic mitral regurgitation, 125 (93.9% were submitted to valve repair. Mean age was 57±15 years and 52 patients were males. The most common etiologies were degenerative disease (73 patients and rheumatic disease (34 patients. Early mortality was 2.4% and late survival was 84.3% at 10 years, which are similar to the age- and gender-matched general population. Only two patients developed severe mitral regurgitation, and both were reoperated (95.6% at 10 years. Freedom from mitral valve failure was 84.5% at 10 years, with no difference between degenerative and rheumatic valves. Overall, late ≥ moderate tricuspid regurgitation was present in 34% of the patients, being more common in the rheumatic ones. The use of tricuspid annuloplasty abolished this complication. Conclusion: We have demonstrated that mitral regurgitation due to organic mitral valve disease from various etiologies can be surgically treated with a high repair rate, low early mortality and long-term survival that are comparable to the matched general population. Concomitant treatment of atrial fibrillation and tricuspid valve may be important adjuncts to optimize long

    Mitochondrial diseases are a heterogeneous group of disorders in which a primary mitochondrial dysfunction is proven by morphological, biochemical, and genetic examinations. The mitral valve has important function in the regulation of blood flow from one chamber to another. Often, the mitral valve becomes abnormal with age, in Rheumatic fever or it is abnormal from birth (Congenital) or it can be destroyed by infection i.e. bacterial endocarditis and needs replacement.

  1. Diffuse Alveolar Hemorrhage due to Acute Mitral Valve Regurgitation

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available 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.

    Rheumatic fever and rheumatic heart disease (RHD) are important health problems in developing countries. The study aim was to provide a review and content analysis of the scientific literature on rheumatic fever and RHD over a 70-year period. Medline was employed via the online PubMed service of the US National Library of Medicine, to search for all documents containing the MeSH terms 'rheumatic fever' or 'rheumatic heart disease' between January 1945 and December 2013. A total of 18,552 references was retrieved. Between 1945 and 1970 the number of annual publications containing the search terms increased, but decreased between 1971 and 2013. Between 1990 and 2013, national collaboration (co-authorship) was greatly increased, from 8.7% to 41.7% of the total reports. International collaboration also increased, from 2.5% to 14.8% (p = 0.001). The United States was the main collaborating country, sharing ties mainly with India, South Africa and Brazil. A content analysis led to the identification of three prominent core research topics, chief among which were heart diseases (rheumatic fever diseases, mitral valve diseases and endocarditis). Other areas of note included streptococcal infections and rheumatic diseases (which, in addition to rheumatic fever, also highlighted arthritis and juvenile arthritis). Publications on rheumatic fever and RHD had a major impact during the 1960s, but research groups interest has since declined overall, in line with a decreasing interest in these diseases in developed countries. In contrast, national and international collaboration has increased, a phenomenon that should be encouraged for research into these and other diseases that affect developing countries.

    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.

    This study was undertaken to assess the ability of cine MR imaging to evaluate the direction, timing, and severity of mitral regurgitation in patients with mitral valve prolapse (MVP). The population of this study was 33 patients with MVP diagnosed by two-dimensional echocardiography and 10 patients with rheumatic mitral valve disease (MSR) for comparison. 7 patients with MVP and 5 with MSR had atrial fibrillation and/or history of congestive heart failure as complications. Mitral regurgitation was graded for severity by color Doppler flow imaging in all patients. Direction and size of systolic flow void in the left atrium were analyzed by contiguous multilevel cine MR images and the maximum volumes of flow void and left atrium were measured. Although flow void was found at the center of the left atrium in most of MSR, it was often directed along the postero-caudal atrial wall in anterior leaflet prolapse and along the anterocranial atrial wall in posterior leaflet prolapse. In MVP, the maximum volume of flow void was often seen in late systole. The maximum volume of flow void and that of left atrium were significantly larger in patients with atrial fibrillation and/or history of congestive heart failure. The length and volume of flow void were increased with clinical severity and degree of regurgitation determined by color Doppler flow imaging. Thus cine MR imaging provides a useful means for detection and semiquantitative evaluation of mitral regurgitation in subjects with MVP. (author)

    Full Text Available Fibroblastic rheumatism (FR is a rare dermoarthopathy reported from different parts of the world since 1980. Although the exact cause is unknown, few reports implicate infection may be a triggering event. Patients usually present with multiple skin nodules and polyarthropathy with progressive skin contractures. Laboratory parameters including acute phase reactants are usually normal. The confirmatory diagnosis is based on histopathologic study of skin nodules, which demonstrate fibroblastic proliferation, thickened collagen fibers, dermal fibrosis, and decreased number of elastic fibers. Immunoreactivity for b-catenin, smooth muscle actin, and the monoclonal antibody HHF35 show myofibroblastic differentiation. Treatments with oral prednisolone and other disease-modifying drugs such as methotrexate, infliximab, and interferon have been tried with variable success. In general, skin lesions respond more aptly than joint symptoms indicating that skin fibroblast is more amenable to treatment than synovial fibroblasts. Awareness regarding this orphan disease among clinicians and pathologists will help in more reporting of such cases and finding out optimal treatment regimen.

    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.

    Background: Acute rheumatic fever and its sequels, rheumatic heart diseases, remain major unsolved preventable health problems in Kosovo population, particularly among the disadvantages indigenous Albanian and Egyptians people. In Kosovo, despite of performing secondary prophylaxis with benzathine penicillin, acute rheumatic fever hospitalization rates have remained essentially unchanged for the last 20 years. The role of echocardiography in the diagnosis of acute rheumatic carditis was established over the last 20 years. Aims: In this study we aimed to determine the prevalence of rheumatic heart disease in children from Kosovo population with first attack of acute rheumatic fever. Also, we presented that echocardiography examination detects a greater prevalence of rheumatic heart disease than other diagnostic procedures. We aimed to compare the sensitivity and specificity of cardiac auscultation, ECG record, lab analysis to echocardiography and to determine the feasibility of specific age in this setting. Methods: To optimize accurate diagnosis of rheumatic fever and rheumatic heart disease, we utilized two group models. In the first group of 388 children, hospitalized and treated before 1999, diagnosis of rheumatic fever was decided basing on the clinical and laboratory findings whereas in second group (221 children treated from1999 to 2010) clinical and lab diagnosis were amplified also on the detection by echocardiography. Conclusion: In second group, using echocardiography as a method of diagnosis and assessment children with rheumatic fever, we found high rates of undetected rheumatic heart disease in this high-risk group population. Echocardiographic examination of children with rheumatic fever for rheumatic heart disease may over diagnose rheumatic heart disease unless congenital mitral valve anomalies and physiological regurgitation are excluded.

    Performance of tricuspid annuloplasty (TA) in patients undergoing mitral valve surgery is recommended based on the degree of tricuspid regurgitation and tricuspid annulus size, but is often underused. To evaluate the impact of combined TA on in-hospital outcome in patients undergoing mitral valve replacement (MVR). We selected all consecutive patients who underwent MVR for native valve disease. Clinical, echocardiographic and in-hospital complications were obtained from chart review. We identified 287 patients (mean age 62±17 years; 44% men). Combined TA was performed in 165 patients (57%), who had more rheumatic disease (71% vs. 24%; P<0.0001) and mitral stenosis (55% vs. 22%; P<0.0001), but less endocarditis (4% vs. 31%; P<0.0001), were more often in atrial fibrillation (54% vs. 22%; P<0.0001), were more severely symptomatic (80% vs. 57%; P<0.0001), presented with a higher systolic pulmonary artery pressure (SPAP) (53±16 vs. 45±15mmHg; P=0.0002) and were less likely to have required emergency surgery (17% vs. 38%; P<0.0001). Despite this higher risk profile, in-hospital mortality was slightly lower (5% vs. 13%; P=0.02) and complication rates were similar (redo surgery 22% vs. 16% [P=0.18] and tamponade 20% vs. 15% [P=0.15]). After adjustment for age, sex, functional class, SPAP, emergency surgery and concomitant coronary artery bypass graft or aortic valve replacement surgery, combined TA was not associated with an increased rate of in-hospital death (P=0.08) or major complications (P=0.89). In a consecutive series of patients who underwent MVR, TA did not seem to have a negative impact on immediate outcome. Hence, additional performance of TA at the time of MVR should not be declined on the basis of an increased surgical risk. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

The population of this study was 33 patients with MVP diagnosed by two-dimensional echocardiography and 10 patients with rheumatic mitral valve disease (MSR) for comparison. 7 patients with MVP and 5 with MSR had atrial fibrillation and/or history of congestive heart failure as complications. Mitral regurgitation was graded for severity by color Doppler flow imaging in all patients. Direction and size of systolic flow void in the left atrium were analyzed by contiguous multilevel cine MR images and the maximum volumes of flow void and left atrium were measured. Although flow void was found at the center of the left atrium in most of MSR, it was often directed along the postero-caudal atrial wall in anterior leaflet prolapse and along the anterocranial atrial wall in posterior leaflet prolapse. In MVP, the maximum volume of flow void was often seen in late systole. The maximum volume of flow void and that of left atrium were significantly larger in patients with atrial fibrillation and/or history of congestive heart failure. The length and volume of flow void were increased with clinical severity and degree of regurgitation determined by color Doppler flow imaging. Thus cine MR imaging provides a useful means for detection and semiquantitative evaluation of mitral regurgitation in subjects with MVP. (author).

    The authors studied 50 patients who had spinal stenosis by means of MR imaging. All patients had undergone myelography and CT. Thirty patients underwent surgery. MR imaging included T1-weighted spin echo sequences with repetition time = 600 msec, echo time = 20 (600/20) sagittal and axial sections 4 mm thick with 2 mm gap. T2-weighted 2,000/60 axial images were obtained on 14 patients. Examinations were retrospectively evaluated for central stenosis, lateral recess narrowing, and foraminal encroachment. Measurements of sagittal, interpedicular, interfacet, and recess dimensions were made at L3-5. On MR images, 20 patients had single-level and 30 had multiple-level stenosis. There was excellent agreement between modalities with central canal stenosis, but a discrepancy in six patients with bony foraminal stenosis. MR imaging was an accurate method for assessment of lumbar stenosis, but CT appears marginally better for detection of bony foraminal stenosis in certain cases

    To study the immediate clinical, echocardiographic and hemodynamic results of 200 patients who underwent percutaneous mitral balloon valvotomy (PMV) with double balloon technique. Two hundred patients were submitted to PVM for treatment of congestive heart failure secondary to severe mitral stenosis, between August 1987 to July 1991. Their mean age was 35.2 years, and 86.5% were female patients: 81% of them was in functional class, New York Heart Association (NYHA) III or IV; 4% was in atrial fibrilation and 4% had previous surgical commissurotomy. PMV was successfully performed in 89% of the patients. The mitral valve area, by pressure half time method, increased from 0.91 +/- 0.27 to 2.10 +/- 0.47 cm2, p atrial septum could not be performed. Mitral regurgitation (MR) immediately after PMV appeared 1+ or more grade in 50 patients, increased in 8 patients and remained unchanged in 11 patients. Ten patients needed mitral valve replacement in the first 48h after PMV, for treatment of severe MR. PMV produces excellent immediate results and can be considered an alternative to surgery for the relief of mitral stenosis.

    Menopause occurs naturally in women at about 50 years of age. There is a wealth of data concerning the relationship of menopause to systemic lupus erythematosus, rheumatoid arthritis, and osteoarthritis; there are limited data concerning other rheumatic diseases. Age at menopause may affect the risk and course of rheumatic diseases. Osteoporosis, an integral part of inflammatory rheumatic diseases, is made worse by menopause. Hormone replacement therapy has been studied; its effects vary depending on the disease and even different manifestations within the same disease. Cyclophosphamide can induce early menopause, but there is underlying decreased ovarian reserve in rheumatic diseases. Published by Elsevier Inc.

    Patients with mitral stenosis have usually blunted pulmonary venous (PV) flow, because of decreased mitral valve area and diastolic dysfunction. The authors compared changes in Doppler PV velocities by using transesophageal echocardiography (TEE) against hemodynamics parameters before and after mitral balloon valvotomy to observe relevance of PV velocities and endsystolic left atrial (LA) pressure-volume relationship. In 25 patients (aged 35 +/- 17 years) with mitral stenosis in sinus rhythm, changes in LA pressure and volumes were compared with PV velocities before and after valvotomy. Mitral valve area, mitral gradients, and deceleration time were obtained. Mitral valve area and mitral gradients changed from 1 +/- 0.2 cm2 and 14.6 +/- 5.4 mmHg to 1.9 +/- 0.3 cm2 and 6.3 +/- 1.7 mmHg, respectively (pLA pressure were correlated with changes in S/D (r=0.57, pLA pressure-volume relationship were also correlated with changes in S/D (r=0.52, pLA pressure-volume relationship decreased after mitral balloon valvotomy, as a result of a large decrease in pressure. PV systolic/diastolic (S/D) waves ratio reflects endsystolic LA pressure-volume relationship and may be used as another indicator of successful valvotomy.

    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.

  20. Redo mitral valve surgery

    Full Text Available This study is based on the findings of a single surgeon’s practice of mitral valve replacement of 167 patients from April 2005 to June 2017 who developed symptomatic mitral restenosis after closed or open mitral commisurotomy. Both clinical and color doppler echocardiographic data of peri-operative and six months follow-up period were evaluated and compared to assess the early outcome of the redo mitral valve surgery. With male-female ratio of 1: 2.2 and after a duration of 6 to 22 years symptom free interval between the redo procedures, the selected patients with mitral valve restenosis undergone valve replacement with either mechanical valve in 62% cases and also tissue valve in 38% cases. Particular emphasis was given to separate the adhered pericardium from the heart completely to ameliorate base to apex and global contraction of the heart. Besides favorable post-operative clinical outcome, the echocardiographic findings were also encouraging as there was statistically significant increase in the mitral valve area and ejection fraction with significant decrease in the left atrial diameter, pressure gradient across the mitral valve and pulmonary artery systolic pressure. Therefore, in case of inevitable mitral restenosis after closed or open commisurotomy, mitral valve replacement is a promising treatment modality.

    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.

    It is fairly easy to detect advanced valve lesions of established rheumatic heart disease by echocardiography in the clinically identified cases of rheumatic heart disease. However, to diagnose a subclinical case of rheumatic heart disease, no uniform set of echocardiographic criteria exist. Moderate thickening of valve leaflets is considered an indicator of established rheumatic heart disease. World Health Organization criteria for diagnosing probable rheumatic heart disease are more sensitive and are based on the detection of significant regurgitation of mitral and/or aortic valves by color Doppler. We attempted diagnosing RHD in school children in Bikaner city by cardiac ultrasound. The stratified cluster sampling technique was employed to identify 31 random clusters in the coeducational schools of Bikaner city. We selected 1059 school children aged 6-15 years from these schools. An experienced operator did careful cardiac auscultation and echocardiographic study. A second expert confirmed the echocardiographic findings. The prevalence of lesions suggestive of rheumatic heart disease by echocardiography was 51 per 1,000 (denominator = 1059; 95% CI: 38-64 per 1,000). We were able to clinically diagnose RHD in one child. None of these children or their parents having echocardiographic evidence of RHD could provide a positive history of acute rheumatic fever. By echocardiographic screening, we found a high prevalence of rheumatic heart disease in the surveyed population. Clinical auscultation had much lower diagnostic efficacy.

    Calcific aortic stenosis is the most common cause of aortic valve replacement in developed countries, and this condition increases in prevalence with advancing age. The fibrotic thickening and calcification are common eventual endpoint in both non-rheumatic calcific and rheumatic aortic stenoses. New observations in human aortic valves support the hypothesis that degenerative valvular aortic stenosis is the result of active bone formation in the aortic valve, which may be mediated through a process of osteoblast-like differentiation in these tissues. Additionally histopathologic evidence suggests that early lesions in aortic valves are not just a disease process secondary to aging, but an active cellular process that follows the classical "response to injury hypothesis" similar to the situation in atherosclerosis. Although there are similarities with the risk factor and as well as with the process of atherogenesis, not all the patients with coronary artery disease or atherosclerosis have calcific aortic stenosis. This review mainly focuses on the potential vascular and molecular mechanisms involved in the pathogenesis of aortic valve stenosis. Namely extracellular matrix remodeling, angiogenesis, inflammation, and eventually osteoblast-like differentiation resulting in bone formation have been shown to play a role in the pathogenesis of calcific aortic stenosis. Several mediators related to underlying mechanisms, including growth factors especially transforming growth factor-beta1 and vascular endothelial growth factors, angiogenesis, cathepsin enzymes, adhesion molecules, bone regulatory proteins and matrix metalloproteinases have been demonstrated, however the target to be attacked is not defined yet.

    Fasting is one of the important religious practices of Muslims, in which the individuals abstain from eating and drinking from dawn to sunset. Fasting is not obligatory or even not allowed, in case it causes health problems to the fasting individual. Rheumatic diseases are a major group of chronic diseases which can bring about numerous problems while fasting. The aim of this article is to review the impact of Islamic fasting on rheumatic patients, based on the scientific evidences.

    Prosthetic heart valve dysfunction due to thrombus or pannus formation can be a life-threatening complication. The present report describes a 47-year-old woman who developed valvular cardiomyopathy after chorda-sparing mitral valve replacement, and subsequently underwent heart transplantation for progressive heart failure. The explanted mitral valve prosthesis showed significant thrombus and pannus leading to reduced leaflet mobility and valvular stenosis. The present report illustrates the role of the subvalvular apparatus and pannus in prosthesis dysfunction. PMID:19279993

    The study has focused on the retrospective analysis of cases of coexisting congenital aortic stenosis (AS) and pulmonary artery stenosis (PS) in dogs. The research included 5463 dogs which were referred for cardiological examination (including clinical examination, ECG and echocardiography) between 2004 and 2014. Aortic stenosis and PS stenosis were detected in 31 dogs. This complex defect was the most commonly diagnosed in Boxers - 7 dogs, other breeds were represented by: 4 cross-breed dogs, 2 Bichon Maltais, 3 Miniature Pinschers, 2 Bernese Mountain Dogs, 2 French Bulldogs, and individuals of following breeds: Bichon Frise, Bull Terrier, Czech Wolfdog, German Shepherd, Hairless Chinese Crested Dog, Miniature Schnauzer, Pug, Rottweiler, Samoyed, West Highland White Terrier and Yorkshire Terrier. In all the dogs, the murmurs could be heard, graded from 2 to 5 (on a scale of 1-6). Besides, in 9 cases other congenital defects were diagnosed: patent ductus arteriosus, mitral valve dysplasia, pulmonary or aortic valve regurgitation, tricuspid valve dysplasia, ventricular or atrial septal defect. The majority of the dogs suffered from pulmonary valvular stenosis (1 dog had supravalvular pulmonary artery stenosis) and subvalvular aortic stenosis (2 dogs had valvular aortic stenosis). Conclusions and clinical relevance - co-occurrence of AS and PS is the most common complex congenital heart defect. Boxer breed was predisposed to this complex defect. It was found that coexisting AS and PS is more common in male dogs and the degree of PS and AS was mostly similar.

    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.

    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.

    Full Text Available Background: Hemodynamic changes induced by labor pain and apprehension in addition to physiological changes may pose risk to parturients with rheumatic heart disease (RHD. Therefore, it is important to provide adequate pain relief during labor in these patients. We planned this study to compare the efficacy and safety of epidural (E versus combined spinal - epidural (CSE for labor analgesia in parturients with rheumatic valvular heart disease. Methods: Twenty-five parturients with RHD included in this study were randomized to one of the two groups - E group (n = 12, received 6 mL of 0.0625% bupivacaine with 25 μg fentanyl or CSE group (n = 13, received 25 μg of fentanyl with 1.25 mg bupivacaine diluted to 1 mL in subarachnoid space. Afterward, a continuous infusion of 0.1% bupivacaine with 2 μg/mL fentanyl was started at 6-8 mL/h. Primary outcome, analgesic efficacy, was assessed by visual analog scale (VAS for pain. VAS ≤ 3 was considered as effective analgesia. Rescue analgesia in the form of epidural bolus was given if VAS > 3. Results: Demographic characteristics of the patients were comparable. Mitral stenosis was the predominant valvular lesion. The VAS at which the parturients received analgesia was comparable. The mean time to achieve effective analgesia was significantly faster in CSE group (4.46 ± 0.87 min compared with group E (15.09 ± 5.7 min (P < 0.001. Significantly lower median pain scores were recorded until the initial 15 min in CSE group. Afterward, median VAS for pain was comparable between the groups. VAS for pain was significantly low at all time intervals than baseline in both the groups. Maternal satisfaction and incidence of cesarean rate and complication were comparable between the groups. Conclusion: Both epidural and CSE are equally effective and safe for labor analgesia in parturients with rheumatic valvular heart disease. However, CSE technique provides a faster onset of analgesia.

    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.

    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.

    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

    Full Text Available Objective. To study proinflammatory cytokines and brain natriuretic peptide (BNP in patients with rheumatic heart diseases (RHD and coronary heart disease (CHD complicated by chronic heart insufficiency (CHI. Material and methods. 54 pts with CHI (among them 16 with RHD and 38 with CHD with signs of CHI ofll-IV functional class according to NYHA that correspond to 11A-III stage according to N.D. Strazesko-V.H. \\frsilenko classification and 30 healthy persons of control group were examined. Besides clinical evaluation common laboratory and instrumental methods were used. Thorough echocardiography analysis, quantitative evaluation of serum TNF a, IL6 and BNP by immuno-enzyme assay was performed. Results. Direct correlation between cytokines and BNP levels and pts with CHI clinical state severity was revealed. These indiccs significantly differed in coronary and non-coronary (RHD CHI. TNF a concentration was minimal in mitral stenosis. Maximal concentrations of IL6 and TNF a were revealed in tricuspid regurgitation. TNF a concentration elevated with increase of heart linear dimensions. BNP showed similar but less prominent tendencies. Conclusion. Significant difference of studied indices in coronary and non-coronary (RHD CHI was shown. Despite of similarity of CHI clinical features levels of inflammation biological indices in RHD was significantly lower than in CHD that requires further discussion.

    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.

    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.

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.

    This study aimed to evaluate the safety and feasibility of transaortic mitral pannus removal (TMPR).Methods and Results:Between 2004 and 2016, 34 patients (median age, 57 years; 30 women) with rheumatic disease underwent pannus removal on the ventricular side of a mechanical mitral valve through the aortic valve during reoperation. The median time interval from the previous surgery was 14 years. TMPR was performed after removal of the mechanical aortic valve (n=21) or diseased native aortic valve (n=11). TMPR was performed in 2 patients through a normal aortic valve. The mitral transprosthetic mean pressure gradient (TMPG) was ≥5 mmHg in 11 patients, including 3 with prosthetic valve malfunction. Prophylactic TMPR was performed in 23 patients. There were no early deaths. Concomitant operations included 22 tricuspid valve surgeries (13 replacements, 15 repairs) and 32 aortic valve replacements (24 repeats, 8 primary). The mean gradient in patients who had mitral TMPG ≥5 mmHg was significantly decreased from 6.46±1.1 to 4.37±1.17 mmHg at discharge (Ppannus overgrowth in such valves.

    The periodontal disease during pregnancy of women with rheumatic valve disease imply infective endocarditis risks and higher rate of preterm birth and low birth weight. To study the periodontal disease rate of women with rheumatic valve disease during pregnancy. We studied 140 pregnant women who included 70 patients with rheumatic valve disease and 70 healthy women. The periodontal examination included: 1) periodontal clinical exam regard the follow variables: a) probing depth; b) gingival margin; c) clinical attachment level; d) bleeding on probing; e) plaque index and f) gingival index; and 2) microbiological test was performed in samples serum and gingival crevicular fluid and considered positive controls to Porphyromonas gingivalis, Tannerella forsithia e Aggregobacter actinomycetemcomitans. Age and parity were similar between groups; as single or combined the mitral valve disease was prevalent among the rheumatic valve lesion in 45 (32.1%) e 20 (28.5%) cases, respectively. Among the periodontal variables gingival margin (p=0.01) and plaque index (p=0.04) were different between groups. The periodontal disease was identified in 20 (14,3%) pregnant women, seven (10%) of them were patients with valve rheumatic disease and the remain 13 (18,6%) were healthy women, its percentual was not different between groups (p=0,147). Microbiological analyses of oral samples showed higher percentual of P. gingivalis in healthy pregnant women (p=0.004). The clinical and microbiological study during pregnancy showed comparable incidence of periodontal disease between women with rheumatic valve disease and healthy women.

    Calprotectin is a heterodimer formed by two proteins, S100A8 and S100A9, which are mainly produced by activated monocytes and neutrophils in the circulation and in inflamed tissues. The implication of calprotectin in the inflammatory process has already been demonstrated, but its role in the pathogenesis, diagnosis, and monitoring of rheumatic diseases has gained great attention in recent years. Calprotectin, being stable at room temperature, is a candidate biomarker for the follow-up of disease activity in many autoimmune disorders, where it can predict response to treatment or disease relapse. There is evidence that a number of immunomodulators, including TNF-α inhibitors, may reduce calprotectin expression. S100A8 and S100A9 have a potential role as a target of treatment in murine models of autoimmune disorders, since the direct or indirect blockade of these proteins results in amelioration of the disease process. In this review, we will go over the biologic functions of calprotectin which might be involved in the etiology of rheumatic disorders. We will also report evidence of its potential use as a disease biomarker. Impact statement Calprotectin is an acute-phase protein produced by monocytes and neutrophils in the circulation and inflamed tissues. Calprotectin seems to be more sensitive than CRP, being able to detect minimal residual inflammation and is a candidate biomarker in inflammatory diseases. High serum levels are associated with some severe manifestations of rheumatic diseases, such as glomerulonephritis and lung fibrosis. Calprotectin levels in other fluids, such as saliva and synovial fluid, might be helpful in the diagnosis of rheumatic diseases. Of interest is also the potential role of calprotectin as a target of treatment.

    Full Text Available Background: There have been a number of studies on mitral valve replacement and repeated percutaneous mitral balloon valvotomy for mitral valve restenosis after percutaneous mitral balloon valvotomy. However, studies on mitral valve repair for these patients are rare. In this study, we analyzed postoperative outcomes of mitral valve repair for mitral valve restenosis after percutaneous mitral balloon valvotomy. Methods: In this study, we assessed 15 patients (mean age, 47.7±9.7 years; 11 female and 4 male who underwent mitral valve repair between August 2008 and March 2013 for symptomatic mitral valve restenosis after percutaneous mitral balloon valvotomy. The mean interval between the initial percutaneous mitral balloon valvotomy and the mitral valve repair was 13.5±7 years. The mean preoperative Wilkins score was 9.4±2.6. Results: The mean mitral valve area obtained using planimetry increased from 1.16±0.16 cm2 to 1.62±0.34 cm2 (p=0.0001. The mean pressure half time obtained using Doppler ultrasound decreased from 202.4±58.6 ms to 152±50.2 ms (p=0.0001. The mean pressure gradient obtained using Doppler ultrasound decreased from 9.4±4.0 mmHg to 5.8±1.5 mmHg (p=0.0021. There were no early or late deaths. Thromboembolic events or infective endocarditis did not occur. Reoperations such as mitral valve repair or mitral valve replacement were not performed during the follow-up period (39±16 months. The 5-year event-free survival was 56.16% (95% confidence interval, 47.467–64.866. Conclusion: On the basis of these results, we could not conclude that mitral valve repair could be an alternative for patients with mitral valve restenosis after percutaneous balloon mitral valvotomy. However, some patients presented with results similar to those of mitral valve replacement. Further studies including more patients with long-term follow-up are necessary to determine the possibility of this application of mitral valve repair.

    Introduction Epidemiological studies of rheumatic diseases have been conducted during the past 20 years in China. The aim of this study was to clarify prevalence rates of common rheumatic diseases in China. Methods Relevant reports of population-based surveys conducted from 1980 to 2006 were retrieved. Studies using the World Health Organization-International League of Associations for Rheumatology COPCORD (Community Oriented Program for Control of Rheumatic Diseases) protocol and those that did not employ this protocol but were published in recognized journals were identified and analyzed. Results Thirty-eight surveys including 241,169 adults from 25 provinces/cities were pooled for analysis. The prevalence of rheumatic complaints ranged from 11.6% to 46.4%, varying by locality, study protocol and age of the people surveyed. Prevalence of symptomatic osteoarthritis (OA) varied from 5.1% to 20.8%, with common sites of involvement being the lumbar spine, knee joint and cervical spine. Compared with rates of radiographic and symptomatic knee OA in the USA, elderly men in Beijing exhibited similar prevalence rates and elderly women exhibited a higher prevalence. The prevalence of hip OA and hand OA was much lower in Chinese than in Caucasian populations, but both kinds of OA were more common in coal miners. The prevalence of ankylosing spondylitis ranged from 0.2% to 0.54% among Han ethnic Chinese and were lower among mixed ethnic populations. The prevalence of psoriatic arthritis ranged from 0.01% to 0.1%, and that of reactive arthritis was 0.02%; undifferentiated spondyloarthropathy was identified in 0.64% to 1.2% of the individuals included in the surveys. The prevalence of rheumatoid arthritis (RA) ranged from 0.2% to 0.93%, with the highest rate being reported from a Taiwan urban area. In mainland China there were no significant differences in prevalence of RA between the northern and southern parts of China, or between different ethnic groups. The prevalence of

    Full Text Available To evaluate the impact of surgical strategy in concomitant mitral valve surgery or isolated aortic valve replacement (AVR in patients with moderate secondary mitral regurgitation (MR, 1 574 patients underwent AVR over a period from January 2003 to December 2011. 241 patients had secondary MR 2+ and constituted the study population. Patients were stratified into two groups, those without concomitant mitral valve surgery (Group A, n = 113 and with it (Group B, n = 128. It was found out that AVR plastic correction of MI reduces its recurrence during short-term follow-up but increases the intervention time leading to an insignificant rise in lethality. In patients with aortic stenosis the age exceeding 70 years and the presence of atrial fibrillation are found to be the most significant predictors of preservation of residual mitral regurgitation in the early postoperative period, while more indicative for patients with aortic insufficiency is the presence of tricuspid regurgitation grade 2 or higher.

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.

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

    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.

    Restrictive mitral annuloplasty is the preferred method of treating secondary mitral regurgitation. The use of small annuloplasty rings to reduce the high recurrence rates may result in mitral stenosis. Thirty-six patients who underwent restrictive mitral annuloplasty with Carpentier-Edwards classic 26 size ring underwent exercise echocardiography and ergospirometry. Resting catecholamines and N-terminal pro brain natriuretic peptide (NT-proBNP) levels were measured. At the time of study, the median time from operation was 16.6 months (interquartile range, 8.5 to 43.3 months). Left ventricular end-systolic volume index (LVESVI) was 67 mL/m(2) (interquartile range, 25 to 92 mL/m(2)), and ejection fraction (EF) was 38.8% (interquartile range, 28.3% to 59.0%). Mitral gradients were higher at the leaflet tips than at the annular level. Continuous wave (CW) Doppler gradients at rest were 3.4 mmHg (interquartile range, 2.4 to 4.9 mmHg) mean and 9.5 mmHg (interquartile range, 7.0 to 14.7 mmHg) maximal. On exertion, they increased to 6.8 mmHg (interquartile range, 5.4 to 8.8 mmHg) (p = 0.001) and 19.7 mmHg (interquartile range, 12.8 to 23.3 mmHg) (p = 0.001), respectively. Maximal VO2 was 18.2 mL/kg/min (interquartile range, 16.3 to 21.5 mL/kg/min), VE/VCO2 slope was 31.1 (interquartile range, 26 to 34). Epinephrine level was 0.024 ng/mL (interquartile range, 0.0098 to 0.043 ng/mL), norepinephrine was 0.61 ng/mL (interquartile range, 0.41 to 0.95 ng/mL), and NT-proBNP was 303 pg/mL (interquartile range, 155 to 553 pg/mL). Maximal VO2 negatively correlated with resting norepinephrine level (r = -0.50, p = 0.003). VE/VCO2 slope positively correlated with NT-proBNP (r = 0.36, p = 0.004) and epinephrine (r = 0.36, p = 0.04) levels and with LV volumes (r = 0.51, p = 0.006) and was negatively correlated with LVEF (r = -0.52, p = 0.004). Neither maximal VO2 nor VE/VCO2 slope correlated with the highest mean (r = 0.24, p = 0.2, and r = -0.20, p = 0.3, respectively) and maximal (r

    Full Text Available While the incidence of acute rheumatic fever (ARF in the United States has declined over the past years, the disease remains one of the causes of severe cardiovascular morbidity in children. The index of suspicion for ARF in health care providers may be low due to decreasing incidence of the disease and clinical presentation that can mimic other conditions. We present the case of a 5-year-old boy with a history of intermittent fevers, fatigue, migratory joint pain, and weight loss following group A Streptococcus pharyngitis. The patient presented to the emergency department twice with the complaints described above. On his 3rd presentation, the workup for his symptoms revealed the diagnosis of acute rheumatic fever with severe mitral and aortic valve regurgitation. The patient was treated with penicillin G benzathine and was started on glucocorticoids for severe carditis. The patient was discharged with recommendations to continue secondary prophylaxis with penicillin G benzathine every 4 weeks for the next 10 years. This case illustrates importance of primary prevention of acute rheumatic fever with adequate antibiotic treatment of group A Streptococcus pharyngitis. Parents should also receive information and education that a child with a previous attack of ARF has higher risk for a recurrent attack of rheumatic fever. This can lead to development of severe rheumatic heart disease. Prevention of recurrent ARF requires continuous antimicrobial prophylaxis. Follow-up with a cardiologist every 1-2 years is essential to assess the heart for valve damage.

    Mitral annular calcification (MAC) is common in chronic kidney disease. It is associated with cardiovascular events and can cause valvular dysfunction, but it has not been systematically characterized. The aim of this prospective study was to assess the prevalence and distribution of MAC, its effects on leaflet motion, and its association with mitral stenosis and mitral regurgitation (MR) in a hemodialysis population. Echocardiograms were obtained in 75 consecutive hemodialysis outpatients. MAC extent and distribution were graded semiquantitatively using two-dimensional and three-dimensional echocardiography. Associations with the presence and severity of mitral stenosis and MR were explored. The mean age was 60 ± 14 years; 60% were men, and 87% were African American. MAC was present in 64% (moderate to severe in 48%). Calcium extended more than halfway onto the leaflet in 37% and beyond the annulus in 40%. Leaflet motion was restricted in 37%. Mitral stenosis was present in 28%, and the extent of calcification was associated with mean mitral valve gradient (P < .0001). MR was prevalent (present in 81%) but was severe in none. The severity of MAC was greater in patients with moderate MR than in those with no or mild MR (P = .04). Three-dimensional analysis suggested an uneven distribution of annular calcium; the middle and lateral anterior segments were less often calcified than the anterior-medial or posterior segments. Calcification in any annular segment was highly associated with restricted motion of the attached leaflet segment. MAC is common and often extensive in hemodialysis patients. Calcium may be unevenly distributed among the annular segments. When present, annular calcification reduces the angle of leaflet opening and can cause valvular dysfunction.

    2011-04-01

    Full Text Available INTRODUCTION: Dextrocardia situs inversus refers to the heart being a mirror image situated on the right side of the body. Distorted cardiac anatomy provides technical difficulties during fluoroscopy‐guided transcatheter procedures. This is even more difficult in the case with percutaneous transvenous mitral commissurotomy (PTMC. Mitral valvuloplasty is a minimally invasive therapeutic procedure to correct an uncomplicated mitral stenosis by dilating the valve using a balloon. Here, we describe a case of a 25 years-old male with situs inversus and dextrocardia. CASE REPORT: A 25 years-old man, having situs inversus and suffering from mitral stenosis was referred to hospital for PTMC. His initial examination findings were unremarkable and an electrocardiographic (ECG, trans-esophageal and transthoracic echocardiographic evaluation were performed. Mitral valve (MV was dome shape and severely stenotic with mild mitral regurgitation (MR. Left ventricular ejection Fraction (LVEF was about 40%, Femoral arterial and venous punctures were made on the left side; the left femoral artery and vein were cannulated with a 5F arterial and 6F venous sheaths, respectively. Then special maneuvers were done to solve the mitral valve stenosis. At the end of the procedure, no MR was documented by checking LV angiogram and there were no signs of mitral stenosis (MS. DISCUSSION: Mirror‐image dextrocardia, as in our case, has been estimated to occur with a prevalence of 1:10,000. However, there are only a few case reports in the literature on PTMC in similar settings. This might be due to the fact that many of these patients undergo surgical commissurotomy due to the technical difficulties involved in a percutaneous procedure in general. Trans-septal catheterization is considered a technical challenge in anatomically malpositioned hearts, as it is fraught with a higher risk of cardiac perforation. Despite the challenging anatomy, PTMC has been demonstrated to be a

    Echocardiography has been proposed as a method to screen children for rheumatic heart disease. The World Heart Federation has established guidelines for echocardiographic screening. In this study, we describe a rapid echocardiogram screening protocol according to the World Heart Federation guidelines in Samoa, endemic for rheumatic heart disease. We performed echocardiogram screening in schoolchildren in Samoa between 2013 and 2015. A brief screening echocardiogram was performed on all students. Children with predefined criteria suspicious for rheumatic hear diseases were referred for a more comprehensive echocardiogram. Complete echocardiograms were classified according to the World Heart Federation guidelines and severity of valve disease. Echocardiographic screening was performed on 11,434 children, with a mean age of 10.2 years; 51% of them were females. A total of 558 (4.8%) children underwent comprehensive echocardiography, including 49 students who were randomly selected as controls. Definite rheumatic heart disease was observed in 115 students (10.0 per 1000): 92 students were classified as borderline (8.0 per 1000) and 23 with CHD. Advanced disease was identified in 50 students (4.4 per 1000): 15 with severe mitral regurgitation, five with severe aortic regurgitation, 11 with mitral stenoses, and 19 with mitral and aortic valve disease. We successfully applied a rapid echocardiographic screening protocol to a large number of students over a short time period - 28 days of screening over a 3-year time period - to identify a high prevalence of rheumatic heart disease. We also reported a significantly higher rate of advanced disease compared with previously published echocardiographic screening programmes.

    Full Text Available Abstract Objective: To assess heart rhythm and predictive factors associated with sinus rhythm after one year in patients with rheumatic valve disease undergoing concomitant surgical treatment of atrial fibrillation. Operative mortality, survival and occurrence of stroke after one year were also evaluated. Methods: Retrospective longitudinal observational study of 103 patients undergoing rheumatic mitral valve surgery and ablation of atrial fibrillation using uni- or bipolar radiofrequency between January 2013 and December 2014. Age, gender, functional class (NYHA, type of atrial fibrillation, EuroSCORE, duration of atrial fibrillation, stroke, left atrial size, left ventricular ejection fraction, cardiopulmonary bypass time, myocardial ischemia time and type of radiofrequency were investigated. Results: After one year, 66.3% of patients were in sinus rhythm. Sinus rhythm at hospital discharge, lower left atrial size in the preoperative period and bipolar radiofrequency were associated with a greater chance of sinus rhythm after one year. Operative mortality was 7.7%. Survival rate after one year was 92.3% and occurrence of stroke was 1%. Conclusion: Atrial fibrillation ablation surgery with surgical approach of rheumatic mitral valve resulted in 63.1% patients in sinus rhythm after one year. Discharge from hospital in sinus rhythm was a predictor of maintenance of this rhythm. Increased left atrium and use of unipolar radiofrequency were associated with lower chance of sinus rhythm. Operative mortality rate of 7.7% and survival and stroke-free survival contribute to excellent care results for this approach.

    Mitral valve prolapse (MVP) results from the systolic movement of a portion(s) or segment(s) of the mitral valve leaflet(s) into the left atrium during left ventricular (LV) systole. It should be emphasised that MVP alone, as defined by imaging techniques, may comprise a non-specific finding because it also depends on the LV volume, myocardial contractility and other LV hemodynamics. Thus, a floppy mitral valve (FMV) should be the basis for the diagnosis of MVP. Two types of symptoms may be defined in these patients. In one group, symptoms are directly related to progressive mitral regurgitation and its complications. In the other group, symptoms cannot be explained only by the degree of mitral regurgitation alone; neuroendocrine dysfunction has been implicated for the explanation of symptoms in this group of patients that today is referred as the FMV/MVP syndrome. When significant mitral regurgitation is present in a patient with FMV/MVP, surgical intervention is recommended. In patients with a prohibitive risk for surgery, transcatheter mitral valve repair using a mitraclip device may be considered. Furthermore, transcatheter mitral valve replacement may represent an option in the near future as clinical trials are underway. In this brief review, the current concepts related to FMV/MVP and FMV/MVP syndrome will be discussed. Copyright © 2016 Hellenic Cardiological Society. Published by Elsevier B.V. All rights reserved.

    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.

    The study objective was to assess the technical and process improvement and clinical outcomes of robotic mitral valve surgery by examining the first 1000 cases performed in a tertiary care center. We reviewed the first 1000 patients (mean age, 56 ± 10 years) undergoing robotic primary mitral valve surgery, including concomitant procedures (n = 185), from January 2006 to November 2013. Mitral valve disease cause was degenerative (n = 960, 96%), endocarditis (n = 26, 2.6%), rheumatic (n = 10, 1.0%), ischemic (n = 3, 0.3%), and fibroelastoma (n = 1, 0.1%). All procedures were performed via right chest access with femoral perfusion for cardiopulmonary bypass. Mitral valve repair was attempted in 997 patients (2 planned replacements and 1 resection of fibroelastoma), 992 (99.5%) of whom underwent valve repair, and 5 (0.5%) of whom underwent valve replacement. Intraoperative postrepair echocardiography showed that 99.7% of patients receiving repair (989/992) left the operating room with no or mild mitral regurgitation, and predischarge echocardiography showed that mitral regurgitation remained mild or less in 97.9% of patients (915/935). There was 1 hospital death (0.1%), and 14 patients (1.4%) experienced a stroke; stroke risk declined from 2% in the first 500 patients to 0.8% in the second 500 patients. Over the course of the experience, myocardial ischemic and cardiopulmonary bypass times (P < .0001), transfusion (P = .003), and intensive care unit and postoperative lengths of stay (P < .05) decreased. Robotic mitral valve surgery is associated with a high likelihood of valve repair and low operative mortality and morbidity. The combination of algorithm-driven patient selection and increased experience enhanced clinical outcomes and procedural efficiency. Copyright © 2017 The American Association for Thoracic Surgery.

    Mitral valve replacement is the procedure of choice in patients with severe mitral valve disease. However, these patients are surviving longer and are thus at an increased risk of prosthesis failure or valve-related complications. Study setting: Inkosi Albert Luthuli Central Hospital, a tertiary referral Hospital in Durban. Study population: All patients undergoing redo mechanical mitral valve replacement surgery between January 2005 and December 2014. Study design: Retrospective analysis of patients undergoing redo mitral valve replacement. Patients were identified from theatre record books, their files were electronically accessed and pertinent information extracted onto a data capture sheet. Information documented included demographics, duration to failure, INR, Albumin, HIV status, clinical findings and outcome. The data was stored on an Excel datasheet. Fifty-eight patients were documented (mean age 32 ± 15.81 years; M:F 1:3). Ten patients (17%) were HIV positive (median CD4 count 478). Mean duration between first surgery and redo was 8.8 years. Thirty-five patients (60%) had no co-morbidities. Presenting features at redo surgery were congestive cardiac failure (27), chest pain (11) and palpitations (17). Mean preoperative Ejection Fraction was 51.65 %. Twenty-nine patients (55%) had emergency redo surgery. Twenty-two patients (75%) had acute prosthetic valve thrombosis. Thirty-two patients had tricuspid regurgitation. Original pathology was documented in 23 patients (40%) as Rheumatic valve disease. Prosthetic valve thrombosis was documented in 31 patients (54%). The most commonly used valve was the On-X. Mean presenting INR was 1.96 + 1.2 and mean presenting serum albumin was 36.7 + 7.8 g/l. Forty-one patients (71%) were found to be compliant to Warfarin therapy prior to redo surgery. Mean ICU stay was 6 +9 days. Two patients died postoperatively. Mean followup was 32 + 26.6 months. Twelve patients (20.7%) developed postoperative complications. Patients

    1988-09-01

    A combined analysis of ventricular contractility and intracardiac hemodynamic compensatory mechanisms was carried out, on the basis of angiocardiographic findings, in 37 patients with rheumatic mitral incompetence. Atrial fibrillation aggravates essentially the defect's hemodynamics, while added tricuspid incompetence is accompanied by a certain off-loading in the lesser circulation network. A grossly perversed phasic structure of intramyocardial stress was noted, apparently being a compensatory mechanism. Reduced specific coronary flow and diastolic perfusion gradient in intact coronary arteries are shown to be causes of clinical angina.

    Impairment of left ventricular (LV) function after mitral valve replacement (MVR) has been the most important factor to determine morbidity and mortality. With this in mind, LV performance in the postoperative period was assessed with and without preservation of papillo-annular continuity in MVR. Between March 1994 and August 1998, a total of 383 valve prostheses (202 MVR, 65 AVR, 58 MVR+AVR) were implanted in 325 patients, 177 of whom underwent MVR with Starr Edwards ball cage prostheses (the study group). Of these 177 patients, 105 had MVR with preservation of the posterior mitral leaflet (group I), and 72 had conventional MVR (group II). Predominant lesions were mitral stenosis in 81, mitral regurgitation in 42, and mixed mitral lesion (MS/MR) in 54. Concomitant tricuspid valve annuloplasty was performed in 13, and atrial septal defect repair in five. Sixteen patients underwent MVR for mitral restenosis. In-vivo performance of the prostheses and LV function was evaluated by M-mode and Doppler echocardiography. At 3-6 months clinical improvement was seen in NYHA class, with reduction in cardiothoracic ratio among patients with preserved papillo-annular continuity, irrespective of lesion type. Significant reductions (p versus 44.64 +/- 8.54 postop.; p versus 41.21 +/- 7.16 postop.; p versus 28.81 +/- 5.79 postop.; p versus 64.47 +/- 7.93; p <0.05). Further analysis of data in group I patients showed significant reductions in left atrial dimensions, LVESD and peak gradient, along with improved ejection fraction compared with conventional (group II) patients. Deterioration in LV function in patients undergoing conventional MVR indicates chordal resection as a putative mechanism. This study supports the concept that maintenance of continuity between the mitral annulus and papillary muscles has a beneficial effect on postoperative LV function, and is particularly important in patients with mitral stenosis with depressed preoperative LV systolic function.

    Rheumatic Hearth Disease (RHD) is still prevalent in our country and a great source of morbidity. This study was done with an objective to determine relative frequency of different valvular lesions of RHD presenting in a tertiary care hospital. Methods: This cross sectional study was conducted at the Cardiology Department of Hayatabad Medical Complex, Peshawar. A total of 171 cases of RHD were included through consecutive sampling technique. Results: There were 64.33% females. Mean age was 25.6 ± 6.95 years ranging from 15 to 40 years. The different percentage of valvular lesions in RHD were MR (59.06%), MS (46.78%), AR (43.85%) and mixed lesions (38.59%). Conclusion: Rheumatic heart disease is a very common disease in our community and mitral regurgitation is a predominant lesion at presentation. Females are usually affected more than males. (author)

    The present study evaluates the feasibility, safety, and efficacy of edge-to-edge repair for moderate secondary/functional mitral regurgitation in patients undergoing aortic valve/root interventions. Sixteen patients underwent transaortic edge-to-edge mitral valve repair. Mitral regurgitation was 2+ in 8 patients and 3+ in 6 patients. Two patients in whom cardiac arrest developed preoperatively had severe (4+) mitral regurgitation. Patients underwent operation for severe aortic regurgitation ± aortic root lesions. The mean left ventricular systolic and diastolic diameters were 51.5 ± 12.8 mm and 70.7 ± 10.7 mm, respectively. Left ventricular ejection fraction ranged from 20% to 60%. Primary surgical procedure included Bentall's ± hemiarch replacement in 10 patients, aortic valve replacement in 5 patients, and noncoronary sinus replacement with aortic valve repair in 1 patient. Severity of mitral regurgitation decreased to trivial or zero in 13 patients, 1+ in 2 patients, and 2+ in 1 patient. There were no gradients across the mitral valve in 9 patients, less than 5 mm Hg in 6 patients, and 9 mm Hg in 1 patient. There was no operative mortality. Follow-up ranged from 2 weeks to 54 months. Echocardiography showed trivial or no mitral regurgitation in 12 patients, 1+ in 2 patients, and 2+ in 2 patients. None of the patients had significant mitral stenosis. The mean left ventricular systolic and diastolic diameters decreased to 40.5 ± 10.3 mm and 58.7 ± 11.6 mm, respectively. Ejection fraction also improved slightly (22%-65%). Transaortic edge-to-edge mitral valve repair is a safe and effective technique to abolish secondary/functional mitral regurgitation. However, its impact on overall survival needs to be studied.

    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.

    Renovascular hypertension is a common cause of pediatric hypertension. In the fraction of cases that are unrelated to syndromes such as neurofibromatosis, patients with a solitary stenosis on a branch of the renal artery are common and can be diagnostically challenging. Imaging techniques...... that perform well in the diagnosis of main renal artery stenosis may fall short when it comes to branch artery stenosis. We report 2 cases that illustrate these difficulties and show that a branch artery stenosis may be overlooked even by the gold standard method, renal angiography....

    Rheumatic fever (RF) and rheumatic heart disease (RHD) are the most-common cardiovascular disease in young people aged 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. PMID:26896274

  8. Durability of mitral valve repair for mitral regurgitation due to degenerative mitral valve disease.

    2015-09-01

    Degenerative diseases of the mitral valve (MV) are the most common cause of mitral regurgitation in the Western world and the most suitable pathology for MV repair. Several studies have shown excellent long-term durability of MV repair for degenerative diseases. The best follow-up results are obtained with isolated prolapse of the posterior leaflet, however even with isolated prolapse of the anterior leaflet or prolapse of both leaflets the results are gratifying, particularly in young patients. The freedom from reoperation on the MV at 15 years exceeds 90% for isolated prolapse of the posterior leaflet and it is around 70-85% for prolapse of the anterior leaflet or both leaflets. The degree of degenerative change in the MV also plays a role in durability of MV repair. Most studies have used freedom from reoperation to assess durability of the repair but some studies that examined valve function late after surgery suggest that recurrent mitral regurgitation is higher than estimated by freedom from reoperation. We can conclude that MV repair for degenerative mitral regurgitation is associated with low probability of reoperation for up to two decades after surgery. However, almost one-third of the patients develop recurrent moderate or severe mitral regurgitation suggesting that surgery does not arrest the degenerative process.

    Rheumatic Heart Disease (RHD) continues to be a major public health problem in developing countries like Pakistan. Objective of this cross sectional-analytical study was to analyze the severity of valvular lesions on echocardiography in patients pre-diagnosed with RHD. Methods: The trans thoracic echocardiographic records of RHD patients from 2004 to 2008 were retrospectively reviewed for type and degree of valvular involvement according to AHA/ACC guidelines. Results: A total of 13,414 patients [7,219 Males (53.8%), 6,195 Females (46.2%)]ranging from 11 to 90 years with a mean age of 42.33 +- 18.976 were studied. On echocardiography, 7,500 (56%) had mitral regurgitation (8.8% severe MR), 6,449(48.2%) had tricuspid regurgitation (7.1% severe TR) and 5,550 (41.4%) had aortic regurgitation (4.8% severe AR). MS was detected in 2,729 (20.3%) patients (15.3% severe MS), AS in 102 (0.8%) and TS in 31 (0.2%) patients. Mixed mitral valve disease was seen in 3,185 (23.7%), mixed aortic valve disease in 222 (1.7%) and mixed tricuspid valve disease in 47 (0.4%) patients. All three valves were involved in 2,826 (21.06%) patients, combination of mitral and aortic valves in 3,103 (23.13%), mitral and tricuspid in 3,784 (28.2 %), and mitral only in 3,701 (27.59%) patients. There was some mitral valve abnormality in all patients. Conclusion: Mitral valve was most commonly affected, while regurgitant lesions were more common than stenotic lesions, and most severe in younger patients. All valvular lesions had almost an equal distribution among the sexes, except aortic regurgitation, which was more common in females. Therefore, echocardiography should be done routinely for patients with RHD, focusing on younger population, to facilitate diagnosis and definitive treatment before complications set in. (author)

    A 77-year-old man presented with exertional dyspnea. He had undergone aortic and mitral valve replacement with tissue valves 6-years earlier. The patient's hemoglobin level was 9.8 g/dl and serum aspartate aminotransferase (70 mU/ml) and lactate dehydrogenase (1,112 mU/ml) were elevated. Echocardiography revealed stenosis of the prosthetic valve in the aortic position with peak flow velocity of 3.8 m/second and massive mitral regurgitation. The patient underwent repeat valve replacement. Pannus formation around both implanted valves was observed. The aortic valve orifice was narrowed by the pannus, and one cusp of the prosthesis in the mitral position was fixed and caused the regurgitation, but they were free from cusp laceration or calcification. The patient's postoperative course was uneventful, and he continues to do well 14 months after surgery.

    Following the encouraging results of several registries and trials, transcatheter aortic valve implantation (TAVI) has been recognized as a valid option in patients with severe aortic stenosis deemed at high or prohibitive risk for surgical treatment. Good procedural success and good clinical outcomes have been showed and very limited data exist on TAVI in the setting of a preexisting mitral prosthesis regarding the technique, potential complications, and outcomes. Here, we report six cases of transfemoral TAVI with a self-expanding bioprosthesis (CoreValve; Medtronic, Inc) in patients who had previously undergone mitral valve replacement. Preprocedural, intraprocedural ve postprocedural outcome and data were analyzed and a brief literature review is also presented. Our experiences show that transfemoral CoreValve implantation can be performed successfully in patients with mechanical and bioprosthetic mitral valves. Copyright © 2016 Elsevier Ireland Ltd.

    The right anterolateral thoracotomy is an alternative technique for surgical approach of mitral valve. In these cases, femoral-femoral bypass still has been used, rising occurrence of complications related to femoral cannulation. Describe the technique and results of mitral valve treatment by right anterolateral thoracotomy using aortic cannulation for cardiac pulmonary bypass (CPB). From 1983 e 2008, 100 consecutive female patients, with average age 35 ±13 years, 96 (96%) underwent mitral valve surgical treatment in the Heart Institute of São Paulo. A right anterolateral thoracotomy approach associated with aortic cannulation was used for CPB. Eighty (80%) patients had rheumatic disease and 84 (84%) patients presented functional class III or IV. Were performed 45 (45%) comissurotomies, 38 (38%) valve repairs, 7(7%) mitral valve replacements, seven (7%) recomissurotomies and three (3%) prosthesis replacement. Sparing surgery was performed in 90 (90%) patients. The average CPB and clamp time were 57 ± 27 min e 39 ± 19 min, respectively. There were no in-hospital death, reoperation due to bleeding and convertion to sternotomy. Introperative complications were related to heart harvest (5%), especially in reoperations (3%). The most important complications in postoperative period were related to pulmonary system (11%), followed by atrial fibrilation (10%) but without major systemic repercussions. The mean inhospital length of stay was 8 ± 3 days. Follow-up was 6.038 patients/month. Actuarial survival was 98.0 ± 1.9% and freedom from reoperation was 81.4 ± 7.8% in 180 months. The right anterolateral thoracotomy associated with aortic cannulation in mitral valve surgery is a simple technique, reproducible and safety.

    Echocardiographic screening for rheumatic heart disease in asymptomatic children may result in early diagnosis and prevent progression. Physician-led screening is not feasible in Malawi. Task shifting to mid-level providers such as clinical officers may enable more widespread screening. Hypothesis With short-course training, clinical officers can accurately screen for rheumatic heart disease using focussed echocardiography. A total of eight clinical officers completed three half-days of didactics and 2 days of hands-on echocardiography training. Clinical officers were evaluated by performing screening echocardiograms on 20 children with known rheumatic heart disease status. They indicated whether children should be referred for follow-up. Referral was indicated if mitral regurgitation measured more than 1.5 cm or there was any measurable aortic regurgitation. The κ statistic was calculated to measure referral agreement with a paediatric cardiologist. Sensitivity and specificity were estimated using a generalised linear mixed model, and were calculated on the basis of World Heart Federation diagnostic criteria. The mean κ statistic comparing clinical officer referrals with the paediatric cardiologist was 0.72 (95% confidence interval: 0.62, 0.82). The κ value ranged from a minimum of 0.57 to a maximum of 0.90. For rheumatic heart disease diagnosis, sensitivity was 0.91 (95% confidence interval: 0.86, 0.95) and specificity was 0.65 (95% confidence interval: 0.57, 0.72). There was substantial agreement between clinical officers and paediatric cardiologists on whether to refer. Clinical officers had a high sensitivity in detecting rheumatic heart disease. With short-course training, clinical officer-led echo screening for rheumatic heart disease is a viable alternative to physician-led screening in resource-limited settings.

    Various genetic and environmental risk factors have been shown to be associated with the incidence of rheumatic diseases. However, the pathogenesis of rheumatic diseases poorly understood. Several studies have shown associations of ABO blood groups with various diseases. Our study aimed to determine whether there is an association between the types of rheumatic diseases and ABO and Rh blood groups. The study included the patients, followed up at the Immunology-Rheumatology clinic between January 2016 and December 2016 for diagnosis of rheumatic disease, who had an ABO Rh blood data. Age, gender, type of rheumatic disease, ABO Rh blood groups were recorded. When 823 patients were assessed for blood types, 42.5% patients had A type, 33.2% had O type, 15.4% had B type, and 8.9% had AB type. There was significant difference in the distribution of blood types in rheumatic diseases. While SpA, vasculitis, UCTD, Behçet's and RA were more common in the patients with A blood type; FMF, SLE, SSc and SjS were more common in the patients with O blood type. In addition, the blood type where all the diseases are observed the least commonly was AB. There was significant difference in the distribution of Rh factor in rheumatic diseases. 92.2% patients were Rh positive and 7.8% patients were Rh negative. In our study, we thought that the higher incidence of different rheumatic diseases in different blood types was associated with different genetic predisposition.

    1985-01-01

    Spinal stenosis, which has attracted increasing attention in recent years, represents an important group of clinical and radiologic entities. Recognition and ultimate surgical management of the many abnormalities found in this group require precise preoperative delineation of the morbid anatomy. Conventional axial tomography provided the first accurate picture of the sagittal dimension, but it was limited by poor contrast resolution. Computerized tomography and ultrasound have finally provided the means for accurate measurement of midsagittal diameter and surface area. It is now possible to provide a preoperative assessment of bony and soft-tissue canal compression and to guide surgical decompression by objective anatomic measurements. True spinal stenosis of the lumbar vertebral canal is a form of compression produced by the walls of the vertebral canal. It involves the whole of the vertebral canal by exerting compression at two of its opposite surfaces. There are two types of stenosis: (1) transport stenosis, wherein the clinical manifestations are due to impeded flow of fluid, which is dependent on the available cross-sectional area of the canal surface of the stenotic structure, and (2) compressive stenosis, which includes abnormal compression of opposing surfaces only. According to these definitions, indentation on the spinal canal by disc protrusion or localized tumor is not considered true spinal stenoses. In this chapter the authors discuss only those conditions that produce true canal stenosis

    We now stand at a critical juncture for rheumatic fever (RF) and rheumatic heart disease (RHD) control. In recent years, we have seen a surge of interest in these diseases in regions of the world where RF/RHD mostly occur. This brings real opportunities to make dramatic progress in the next few years, but also real risks if we miss these opportunities. Most public health and clinical approaches in RF/RHD arose directly from programmes of research. Many unanswered questions remain, including those around how to implement what we know will work, so research will continue to be essential in our efforts to bring a global solution to this disease. Here we outline our proposed research priorities in RF/RHD for the coming decade, grouped under the following four challenges: Translating what we know already into practical RHD control; How to identify people with RHD earlier, so that preventive measures have a higher chance of success; Better understanding of disease pathogenesis, with a view to improved diagnosis and treatment of ARF and RHD; and Finding an effective approach to primary prevention. We propose a mixture of basic, applied, and implementation science. With concerted efforts, strong links to clinical and public health infrastructure, and advocacy and funding support from the international community, there are good prospects for controlling these RF and RHD over the next decade

    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.

    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.

    Mitral regurgitation is a complex disorder involving a multitude of components of the mitral apparatus. With the desire for less invasive treatment approaches, transcatheter mitral valve therapies (TMVT) are directed at these components and available at varying stages of development. Therapeutic advancements and the potential to combine technologies may further improve their efficacy and safety. Transcatheter mitral valve replacement, while preserving the mitral apparatus, may emerge as an alternative or even a more suitable treatment option. In addition, early data on transcatheter mitral valve-in-valve and valve-in-ring implantation are encouraging and this approach may be an alternative to reoperation in the high-risk patient. This review details the expanding functional mechanical designs of current active TMVT.

    Failed surgical mitral valve repair using an annuloplasty ring has traditionally been treated with surgical valve replacement or repair1. For patients at high risk for repeat open heart surgery, placement of a trans-catheter aortic valve (i.e., TAVI valve) within the mitral ring (i.e., Mitral-Valve-in-Ring, MViR) has emerged as a novel alternative treatment strategy2-5 . We describe our experience of a failed mitral valve repair that was successfully treated with a TAVI valve delivered via the trans-septal approach, and summarise the data relating to this emerging treatment strategy.

    Mitral regurgitation (MR) occurs when any of the valve and ventricular mitral apparatus components are disturbed. As MR progresses, left ventricular remodelling occurs, ultimately causing heart failure when the enlarging left ventricle (LV) loses its conical shape and becomes globular. Heart failure and lethal ventricular arrhythmias may develop if the left ventricular end-systolic volume index exceeds 55 ml/m2. These adverse changes persist despite satisfactory correction of the annular component of MR. Our goal was to describe this process and summarize evolving interventions that reduce the volume of the left ventricle and rebuild its elliptical shape. This 'valve/ventricle' approach addresses the spherical ventricular culprit and offsets the limits of treating MR by correcting only its annular component.

    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.

    To analyze the clinical spectrum, laboratory characteristics, and outcomes of monoclonal gammopathy (MG) in patients with rheumatic diseases. Screening for the presence of MG was performed in 872 inpatients with rheumatic diseases from January 2010 to July 2017. A total of 41 patients were enrolled. Their clinical and biological features in addition to outcomes were described. For each patient with primary Sjögren syndrome (pSS), 2 age- and sex-matched pSS patients without MG were selected as controls. Risk factors for the presence of MG and malignant hematological neoplasias were assessed. MG was observed in patients with SS, rheumatoid arthritis, systemic lupus erythematosus, ankylosing spondylitis, primary biliary cirrhosis, polymyositis, hypomyopathic dermatomyositis, psoriatic arthritis, ANCA-associated vasculitis, polyarteritis nodosa, and polymyalgia rheumatic, with SS the most frequent type. Serum M protein was detected in 37 patients. The monoclonal bands identified in serum were 16 IgG (5 κ, 11 λ), 11 IgA (6 κ, 5 λ), 6 IgM (5 κ, 1 λ), and 4 free λ chains. M components were observed in urine in the other 4 patients. High ESR, albumin/globulin inversion, rheumatoid factor positivity, hypergammaglobulinemia, and hypocomplementemia were common features, presented in more than half of the 41 patients. Patients with pSS, when complicated with MG, showed a higher rate of abnormal urine NAG (71.4 vs 15.8%, P = 0.025), higher levels of ESR [55.0 (53.5) mm/h vs 21.0 (31.8) mm/h, P = 0.001], ESSDAI [26.0 (25.0) vs 12.0 (9.0), P = 0.006], and ClinESSDAI scores [24.0 (25.0) vs 10.5 (10.0), P = 0.011]. Multivariate analysis revealed that the disease activity, assessed by either ESSDAI [adjusted OR 1.127 (95%CI 1.015-1.251), P = 0.025] or ClinESSDAI [adjusted OR 1.121 (95%CI 1.011-1.242), P = 0.030], was the only independent risk factor for the presence of MG. During the follow-up, 2 patients had transient serum M protein, 2 had isotype

    Full Text Available Pulmonary vein varix is an unusual cause of a mediastinal mass on a chest radiograph. It may be found as an isolated malformation or as a sequela of pulmonary venous hypertension. We encountered a case presenting with left hemiparesis and a past medical history of rheumatic heart disease. The chest radiograph revealed a well-defined mediastinal mass that turned out to be a hugely dilated pulmonary vein on contrast enhanced computed tomography of the chest. The computed tomography of the brain and upper abdomen revealed bilateral cerebral infarction and splenic infarction. In the literature, one-third of the reported cases of pulmonary vein varix are acquired secondary to mitral valve disease.

    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

    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.

    This paper reports eighteen patients with spondylolysis evaluated with sagittal MR imaging to correlate the factors and degree of faoraminal stenosis at the level of the lysis with clinical findings. Fifteen presented with low back pain, eight with radiculopathy and one with paresthesia in the lower limbs, and two were asymptomatic. The degree of foraminal stenosis, quantified in three grades, was not correlated with the onset of radiculopathy. Three foraminal herniations were responsible for radiculopathy. Presence of isthmic bony tip and fibrocartilage buildup were not correlated with symptoms. Foraminal compression can be demonstrated by MR imaging, but without clinical correlations

    Full Text Available Rheumatoid arthritis is the most common rheumatic disease thatneeds surgical intervention. The most affected joints are the wrists,metacarpophalangeal, interphalangeal, metatarsophalangeal, andknees. The others joints are affected in the development of thedisease. During its progression, the infl ammatory process extendsto the periarticular structures of the connective tissue as tendonsand ligaments. These involvements of soft tissue with osteoarticularinvolvement lead to instability and deformities. Open or arthroscopicsynovectomies lead to pain relief, while tenotomies and tendonstransfer aim to correct deformities, as well as regain function of thejoint. Arthroplasty is an excellent choice in order to have a goodrange of motion, functional and not a painful joint. Arthrodesis ischosen, when there is an intense articular involvement and there isno indication for arthroplasty. Although, it limits the range of motionit can achieve pain relief and function, when performed in the rightangle of fl exion and extension.

    Objectives Mitral valve replacement (MVR) in young children is limited by lack of small prostheses. Our institution began performing MVR with modified, surgically placed, stented jugular vein grafts (Melody valve) in 2010. We sought to describe key echocardiographic features for pre- and post-operative assessment of this novel form of MVR. Methods The pre- and post-operative echocardiograms of 24 patients who underwent Melody MVR were reviewed. In addition to standard measurements, pre-operative potential measurements of the mitral annulus were performed whereby dimensions were estimated for Melody sizing. A ratio of the narrowest subaortic region in systole to the actual mitral valve dimension (SubA:MV) was assessed for risk of post-operative left ventricular outflow tract obstruction (LVOTO). Results Melody MVR was performed at a median of 8.5 months (5.6 kg) for stenosis (5), regurgitation (3), and mixed disease (16). Pre-operatively, actual mitral z-scores measured hypoplastic (median −3.1 for the lateral (lat) dimension; −2.1 for the antero-posterior (AP) dimension). The potential measurements often had normal z-scores with fair correlation with intra-operative Melody dilation (ρ=0.51 and 0.50 for lat and AP dimensions, both p=0.01). A pre-operative SubA:MV <0.5 was associated with post-operative LVOTO, which occurred in four patients. Post-operatively, mitral gradients substantially improved, with low values relative to the effective orifice area of the Melody valve. No patients had significant regurgitation or perivalvar leak. Conclusions Pre-operative echocardiographic measurements may help guide intra-operative sizing for Melody MVR and identify patients at risk for post-operative LVOTO. Acute post-operative hemodynamic results were favorable; however, on-going assessment is warranted. PMID:27523403

    Which imaging modalities are appropriate for the Differential diagnosis of Rheumatic diseases. MRI has far most the highest sensitivity and is unequaled in its brilliant presentation of Anatomy and Pathology. But it is sometimes forgotten, that this is at least in part the result of carefully selected sequences, dedicated to the expected result. In a method totally independent of any result, this should not be the case. In contrary this method should be highly standardised and regardless what will be the findings. This is true for Plain X-ray. It will be shown, that already the outer silhouette of the soft parts with different features of swelling, and differences in density and even more - defects or appositions of the bony silhouette in the majority of cases at least will allow to classify the patient for a group of diseases and in many cases will lead to a definite diagnosis. Differential diagnoses like Rheumatoid Arthritis versus Psoriatic Arthritis or simply but not always simple - inflammatory Arthritis versus degenerative disease - are allowed to be answered definitely, not always so in MRI. The condition of the subchondral bone can give hints, how advanced and how active the disease is at present. Plain X-ray offers high specifity in the differential diagnoses of Rheumatic diseases, it is well standardised and it is a device, to use independent from any suspected findings. So it is the method of choice for questions of differential diagnosis. This is even more true, thinking of the possibility, to investigate all clinically involved regions with not to much extended efforts, whereas MRI and CT are used normally for only one region.

    Introduction Echocardiography is the diagnostic test of choice for latent rheumatic heart disease. The utility of echocardiography for large-scale screening is limited by high cost, complex diagnostic protocols, and time to acquire multiple images. We evaluated the performance of a brief hand-held echocardiography protocol and computer-assisted auscultation in detecting latent rheumatic heart disease with or without pathological murmur. A total of 27 asymptomatic patients with latent rheumatic heart disease based on the World Heart Federation criteria and 66 healthy controls were examined by standard cardiac auscultation to detect pathological murmur. Hand-held echocardiography using a focussed protocol that utilises one view - that is, the parasternal long-axis view - and one measurement - that is, mitral regurgitant jet - and a computer-assisted auscultation utilising an automated decision tool were performed on all patients. The sensitivity and specificity of computer-assisted auscultation in latent rheumatic heart disease were 4% (95% CI 1.0-20.4%) and 93.7% (95% CI 84.5-98.3%), respectively. The sensitivity and specificity of the focussed hand-held echocardiography protocol for definite rheumatic heart disease were 92.3% (95% CI 63.9-99.8%) and 100%, respectively. The test reliability of hand-held echocardiography was 98.7% for definite and 94.7% for borderline disease, and the adjusted diagnostic odds ratios were 1041 and 263.9 for definite and borderline disease, respectively. Computer-assisted auscultation has extremely low sensitivity but high specificity for pathological murmur in latent rheumatic heart disease. Focussed hand-held echocardiography has fair sensitivity but high specificity and diagnostic utility for definite or borderline rheumatic heart disease in asymptomatic patients.

  6. An Asymptomatic Patient with Severe Mitral Regurgitation

    Directory of Open Access Journals (Sweden)

    Blase A. Carabello, MD

    2018-01-01

    Full Text Available In primary mitral regurgitation there are anatomic abnormalities of the mitral valve causing backward flow, placing a hemodynamic burden on the left ventricle. If this burden is severe and prolonged, it leads to left ventricular damage, heart failure, and death. The preferred therapy is restoration of mitral competence through mitral valve repair, which is safer than mitral valve replacement. When repair is performed in a timely fashion, lifespan can be returned to that of a normal individual. Triggers for timely repair include the onset of symptoms and evidence of left ventricular dysfunction as determined by ejection fraction falling toward 60% and/or end-systolic dimension increasing toward 40 mm.

    Emergency aortic valve replacement was performed during an attack of acute rheumatic fever in a 12-year-old black boy. He had an uneventful recovery and has remained asymptomatic 27 months after operation. In the light of this experience and that of others, one might conclude that the decision to operate on these patients should be based on the severity of the haemodynamic derangement rather than on the state of activity in the rheumatic process.

    2014-08-01

    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.

  14. X-ray picture of the heart turn in echocardiographic diagnosis of rheumatic heart disease

    International Nuclear Information System (INIS)

    Grishkevich, A.M.; Goryanina, N.K.

    1986-01-01

    The paper is concerned with X-ray and echocardiographic investigation of the heart in 461 patients with mitral-tricuspidal disease. In 377 (82%) cases a turn of the heart along the longitudinal axis (counter clockwise) to the left and back was revealed. X-ray recognition of the heart turn made it possible to set an echocardiographic sensor to spot some of the cardiac cavities, interventricular septum and valvular apparatus. The correct setting of the echocardiographic sensor resulted in the determination of true sizes of each cardiac cavity, diagnosis of the nature of each valvular lesion and the recognition of such complications of rheumatic heart diseases as valvular calcinosis, left atrial thrombosis and disorder of myocardial contractility

    Full Text Available Abstract Background Mitral valve thickness is used as a criterion to distinguish the classical from the non-classical form of mitral valve prolapse (MVP. Classical form of MVP has been associated with higher risk of mitral regurgitation (MR and concomitant complications. We sought to determine the relation of mitral valve morphology and motion to mitral regurgitation severity in patients with MVP. Methods We prospectively analyzed transthoracic echocardiograms of 38 consecutive patients with MVP and various degrees of MR. In the parasternal long-axis view, leaflets length, diastolic leaflet thickness, prolapsing depth, billowing area and non-coaptation distance between both leaflets were measured. Results Twenty patients (53% and 18 patients (47% were identified as having moderate to severe and mild MR respectively (ERO = 45 ± 27 mm2 vs. 5 ± 7 mm2, p Conclusions In patients with MVP, thick mitral leaflet is not associated with significant MR. Leaflet thickness is probably not as important in risk stratification as previously reported in patients with MVP. Other anatomical and geometrical features of the mitral valve apparatus area appear to be much more closely related to MR severity.

  16. The effect of varying degrees of stenosis on the characteristics of turbulent pulsatile flow through heart valves.

    Many problems and complications associated with heart valves are related to the dynamic behavior of the valve and the resultant unsteady flow patterns. An accurate depiction of the spatial and temporal velocity and rms distributions imparts better understanding of flow related valve complications, and may be used as a guideline in valve design. While the generalized correlation between increased turbulence level and the severity of the stenosis is well established, few studies addressed the issue of the intermittent nature of turbulence and its timing in the cardiac cycle, and almost none assessed the effect of a progressive stenosis on the flow characteristics through heart valves. In this experimental work we simulated the type of flow which is present in normal and stenosed valves and conducted a comprehensive investigation of valve hemodynamics, valvular turbulence and morphology under varying degrees of stenosis. The characteristics of valves and stenoses were simulated closely, to achieve the flow conditions that initiate turbulent flow conditions. Laser Doppler anemometry (LDA) measurements were carried out in a pulse duplicator system distal to trileaflet polyurethane prosthetic heart valves, installed at mitral and aortic positions. The effect of the degree of the stenosis was comparatively studied through the structure of the turbulent jets emerging from normal and stenotic heart valves. Maximum turbulence level was achieved during the decelerating phase and correlated to the severity of the stenosis, followed by relaminarization of the flow during the acceleration phase. The intermittent nature of the turbulence emphasized the importance of realizing the timing of the turbulence production and its spatial location for optimizing current valve designs. The plug flow through the normal aortic valve prosthesis was replaced by jet like behavior for a 65% stenosis, with the jet becoming narrower and stronger for a 90% stenosis.

    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.

    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.)

    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.

    Transoesophageal echocardiography (TEE) and venous intracardiac echocardiography (ICE) are traditionally used to visualize the interatrial septum (IAS) and the tenting effect of the fossa ovalis in patients undergoing percutaneous balloon mitral valvuloplasty (PBMV). The aim of the present study was to assess the comparative efficacy and safety of arterial (intra-aortic) ICE and venous ICE, compared with TEE (traditional approach), in the patients undergoing PBMV. TEE, aortic ICE, and venous ICE were consecutively performed in 50 patients (40 ± 9 years, 86% female). The images of intracardiac structures were obtained from both aortic and right atrial loci. The IAS was visualized using TEE, aortic ICE, and venous ICE. The mean mitral valve area was 1.14 ± 0.2 cm(2), and the mean left atrial volume index was 57.5 ± 12 mL/m(2). The mean size of the visualized septal length was 48 ± 5 mm by TEE, 51 ± 5 mm by aortic ICE, and 33 ± 6 mm by venous ICE. The Bland-Altman test indicated that the 95% limits of agreement for the measurement of septal diameter ranged from -11.0 to +5.9 mm (mean -2.5 mm) between TEE and aortic ICE, -2.8 to +33.5 mm (mean +15.3 mm) between TEE and venous ICE, and -36.6 to +0.8 mm (mean -17.9 mm) between venous and aortic ICE. Standard venous ICE generally tended to yield smaller values compared with TEE and aortic ICE for the measurement of septal length. Furthermore, the view of fossa ovalis and 'tenting effect' was optimal in 11 patients on venous ICE; however, the fossa ovalis and tip of the needle were well visualized in all patients on aortic ICE (P < 0.001). There were no major complications with the use of aortic ICE. Aortic ICE is a superior alternative to venous ICE and facilitates trans-septal puncture in patients with mitral stenosis.

    Despite its high prevalence, little is known about mechanisms of mitral regurgitation in degenerative mitral valve disease apart from the leaflet prolapse itself. Mitral valve is a complex structure, including mitral annulus, mitral leaflets, papillary muscles, chords, and left ventricular walls. All these structures are involved in physiological and pathological functioning of this valvuloventricular complex but up to now were difficult to analyze because of inherent limitations of 2-dimensional imaging. The advent of 3-dimensional echocardiography, computed tomography, and cardiac magnetic resonance imaging overcoming these limitations provides new insights into mechanistic analysis of degenerative mitral regurgitation. This review will detail the contribution of quantitative and qualitative dynamic analysis of mitral annulus and mitral leaflets by new imaging methods in the understanding of degenerative mitral regurgitation pathophysiology. © 2018 American Heart Association, Inc.

  7. Contraception for adolescents with chronic rheumatic diseases

    Directory of Open Access Journals (Sweden)

    Benito Lourenço

    Full Text Available ABSTRACT Contraception is an important issue and should be a matter of concern in every medical visit of adolescent and young patients with chronic rheumatic diseases. This narrative review discusses contraception methods in adolescents with juvenile systemic lupus erythematosus (JSLE, antiphospholipid syndrome (APS, juvenile idiopathic arthritis (JIA and juvenile dermatomyositis (JDM. Barrier methods are safe and their use should be encouraged for all adolescents with chronic rheumatic diseases. Combined oral contraceptives (COC are strictly prohibited for JSLE and APS patients with positive antiphospholipid antibodies. Reversible long-acting contraception can be encouraged and offered routinely to the JSLE adolescent patient and other rheumatic diseases. Progestin-only pills are safe in the majority of rheumatic diseases, although the main concern related to its use by adolescents is poor adherence due to menstrual irregularity. Depot medroxyprogesterone acetate injections every three months is a highly effective contraception strategy, although its long-term use is associated with decreased bone mineral density. COC or other combined hormonal contraceptive may be options for JIA and JDM patients. Oral levonorgestrel should be considered as an emergency contraception method for all adolescents with chronic rheumatic diseases, including patients with contraindication to COC.

  8. Successful thrombectomy of a stuck mechanical prosthetic mitral valve guided by perioperative transesophageal echocardiography and cinefluoroscopy

    2009-03-01

    Full Text Available We describe the case of a 53-year-old man with past history of rheumatic valvular disease who developed acute decompensated heart failure due to thrombosis of his mechanical mitral valve prosthesis. The diagnosis was established after a combined and complementary approach of echocardiography and cinefluoroscopy. Because of the severe heart failure at presentation, the patient was taken to surgery. The intraoperative transesophageal echocardiography was critical to guide a successful thrombectomy procedure. Postoperative pathological findings revealed the presence of thrombus and fibrotic tissue (pannus in the surgical specimens removed from the valve. The success of this case and the treatment choice are supported by the most recent literature data on prosthetic valve thrombosis. We highlight the use of three diagnostic approaches in our patient: echocardiography, cinefluoroscopy and pathology.

    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.

    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

    1981-01-01

    Thirty patients with precordial pain and mitral valve prolapse diagnosed by cineangiography and M-mode echocardiography were submitted to Thallium-201 myocardial stress perfusion scintillography. They were divided into two groups: group I - eighteen patients with mitral valve prolapse and normal coronary arteries, of which ten presented positive exercise stress test (55.6%); eight patients had a negative exercise test. Thallium-201 myocardial stress perfusion scintillagraphy was normal in 14 (77.8%) patients, and four with positive stress perfursion scintillography, (three with inferior perfusion defects and one with a lateral one); group II - twelve patients with mitral valve prolapse and severe coronary artery disease (stenosis >= 60% in at least one main vessel of the coronary circulation), of which nine presented positive exercise stress test (75%) and three negative. Thallium-201 exercise myocardial perfusion scintillography was abnormal in nine (75%), six with stress induced ischemia and three with resting defect. Myocardial perfusion scintillography with Thallium-201 was more sensitive to detect the presence of coronary artery disease in patients with mitral valve prolapse (MVP) than the exercise stress test in spite of the fact that a small number of patients (22%) with MVP and normal coronary arteries exhibited abnormal myocardial stress perfusion during scintillography.

    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. Careful follow-up and timely cardiosurgical correction should be performed, if necessary, in patients with classical MPV. The choice method in these cases is the mitral valve plasty.

    To compare the follow-up results of double valve replacement (DVR) i.e. mitral valve replacement (MVR) and aortic valve replacement (AVR) vs. isolated MVR or AVR for rheumatic heart disease. Study Design: An interventional qausi-experimental study. Prospective follow-up of 493 patients with mechanical heart valves was carried out using clinical assessment, international normalized ratio and echocardiography. Patients were divided into three groups: group I having MVR, group II having AVR and group III having DVR. Survival, time and causes of mortality, and frequency of valve thrombosis, haemorrhage and cerebrovascular haemorrhage was noted in the three groups and described as proportions. Actuarial survival was analyzed by Kaplan-Meier method. There were 493 with 287 (58.3%) in group I, 87 (17.6%) in group II and 119 (24.1%) in group III. Total follow-up was 2429.2 patient (pt)-years. Of 77 (15.6%) deaths, 19 (3.8%) were in-hospital and 58 (11.8%) were late. In-hospital mortality was highest 4 (4.6%) in group II followed by 5 (4.2%) group III and 10 (3.5%) group I. Late deaths were 39 (13.4%) in group I, 9 (10.2%) in group II and 10 (8.3%) in group III. The total actuarial survival was 84.4% with survival of 83%, 85.1%, 87.4% in groups I, II and III respectively. On follow-up valve thrombosis occurred in 12 (0.49%/pt-years) patients; 9 (0.67%/pt-years) group I, 1 (0.22%/pt-years) in group II and 2 (0.31%/pt-years) in group III. Severe haemorrhage occurred in 19 (0.78%/pt-years); 14 in (1.04%/pt-years) in group I, 3 (0.66%/pt-years) group II and 2 (0.31%/pt-years) in group III. Cerebrovascular accidents occurred in 34 (1.3%/pt-years); 26 (1.95%/pt-years) in group I and 4 in groups II (0.89%/pt-years) and III (0.62%/pt-years) each. In patients with rheumatic heart disease having combined mitral and aortic valve disease DVR should be performed whenever indicated as it has similar in-hospital mortality and better late survival as compared to isolated aortic or mitral

    Leaflet escape of prosthetic valve is rare but potentially life threatening. It is essential to make timely diagnosis in order to avoid mortality. Transesophageal echocardiography and cinefluoroscopy is usually diagnostic and the location of the missing leaflet can be identified by computed tomography (CT). Emergent surgical correction is mandatory. We report a case of fractured escape of Edward-Duromedics mitral valve 27 years after the surgery. The patient presented with symptoms of acute decompensated heart failure and cardiogenic shock. She was instantly intubated and mechanically ventilated. After prompt evaluation including transthoracic echocardiography and CT, the escape of the leaflet was confirmed. The patient underwent emergent surgery for replacement of the damaged prosthetic valves immediately. Eleven days after the surgery, the dislodged leaflet in iliac artery was removed safely and the patient recovered well. PMID:23837121

    2016-12-01

    Full Text Available The ultimate goal of treating rheumatic disease is to achieve rapid suppression of inflammation, while at the same time minimizing the toxicities from rheumatic drugs. Different patients have different individual pharmacokinetics that can affect the drug level. Moreover, different factors, such as renal function, age or even different underlying diseases, can affect the drug level. Therefore, giving the same dosage of drugs to different patients may result in different drug levels. This article will review the usefulness of therapeutic drug monitoring in maximizing drug efficacy, while reducing the risk of toxicities in Hydroxychloroquine, Mycophenolate Mofetil, Tacrolimus and Tumor Necrosis Factor inhibitors (TNF Inhibitors.

    Renal artery disease is a potentially correctable cause of hypertension. Previous studies have suggested the utility of duplex sonography in accurately detecting and grading the severity of renal artery stenosis. The purpose of this paper is to evaluate color flow Doppler for this use. Forty-three kidneys were examined by color-flow Doppler and conventional duplex sampling in patients with suspected renovascular hypertension or those undergoing aortography for unrelated reasons. Doppler tracings were obtained from the renal arteries and aorta with calculation of the renal aortic ratio (RAR) and resistive index (RI). Results of Doppler sampling with color flow guidance were compared with aortograms in a blinded fashion

    Atherosclerotic renal artery stenosis (RAS) is the single largest cause of secondary hypertension; it is associated with progressive renal insufficiency and causes cardiovascular complications such as refractory heart failure and flash pulmonary edema. Medical therapy, including risk factor modification, renin-angiotensin-aldosterone system antagonists, lipid-lowering agents, and antiplatelet therapy, is advised in all patients. Patients with uncontrolled renovascular hypertension despite optimal medical therapy, ischemic nephropathy, and cardiac destabilization syndromes who have severe RAS are likely to benefit from renal artery revascularization. Screening for RAS can be done with Doppler ultrasonography, CT angiography, and magnetic resonance angiography. Copyright © 2015 Elsevier Inc. All rights reserved.

    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.

    The percutaneous mitral valve repair procedure (MitraClip) appears to reduce mitral annulus diameter in patients with functional mitral regurgitation, but the relationship between this and regurgitation severity has not been demonstrated. The aim of this study was to determine the effect of mitral annulus remodeling on the reduction of mitral regurgitation in patients with functional etiology. The study included all patients with functional mitral regurgitation treated with MitraClip at our hospital until January 2015. Echocardiogram (iE33 model, Philips) was performed in all patients immediately after device positioning. Changes in the mitral annulus correlated with mitral regurgitation severity, as assessed using the effective regurgitant orifice area. The study included 23 patients (age, 65±14 years; 74% men; left ventricular ejection fraction, 31%±13%; systolic pulmonary artery pressure, 47±10 mmHg). After the procedure, the regurgitant orifice area decreased by 0.30 cm 2 ±0.04 cm 2 (P<.0005), from a baseline of 0.49 cm 2 ±0.09 cm 2 . Anteroposterior diameter decreased by 3.14 mm±1.01 mm (P<.0005) from a baseline of 28.27 mm±4.9 mm, with no changes in the intercommissural diameter (0.50 mm±0.91 mm vs 40.68 mm±4.7 mm; P=.26). A significant association was seen between anteroposterior diameter reduction and regurgitant orifice area reduction (r=.49; P=.020). In patients with functional mitral regurgitation, the MitraClip device produces an immediate reduction in the anteroposterior diameter. This remodeling may be related to the reduction in mitral regurgitation. Copyright © 2016 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U. All rights reserved.

    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.

    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.)

    Lung ailments in rheumatic diseases present unique challenges for diagnosis and management and are a source of significant morbidity and mortality for patients. Unlike the idiopathic interstitial pneumonias, patients with rheumatic diseases experience lung disease in the context of a systemic disease that may make it more difficult to recognize and that may present greater risks with treatment. Despite recent advances in our awareness of these diseases, there is still a significant lack of understanding of natural history to elucidate which patients will have disease that is progressive and thus warrants treatment. What we do know is that a subset of patients with rheumatic disease experience parenchymal lung disease that can prognostically resemble idiopathic pulmonary fibrosis, such as in rheumatoid arthritis, and that others can have aggressive inflammatory lung disease in the context of autoimmune myositis, systemic sclerosis, or an undifferentiated autoimmune process. As we enter into a paradigm shift where we view lung health as a cornerstone of our care of patients with rheumatic diseases, we hopefully will improve our ability to identify those patients at highest risk for pulmonary disease and progression, and offer emerging treatments which will result in better outcomes and a better quality of life.

    In the radiological investigation of joint disease there are several signs which are helpful in making a diagnosis, Individually these signs will often suggest the presence of joint disease but may not be specific. However when present in combination or when considering the anatomic distribution, a definitive diagnosis is possible. Several of the signs of rheumatic disease can occur in other nonrheumatic conditions

    Radiological imaging plays a fundamental role in the diagnosis and monitoring of rheumatic diseases. The basic method of imaging is a classic X-ray picture, which for many years has been used as a single method for the recognition and evaluation of the effects of disease management. In today’s modern day treatment of rheumatic diseases, ultrasonography and magnetic resonance are more commonly performed for early detection of inflammatory changes in the region of soft tissue, subchondral bone and bone marrow. In spite of their usefulness and fundamental role in the diagnosis, X-ray still remains an essential tool in the diagnosis of rheumatoid arthritis in children and is complementary to today’s methods of imaging diagnostics. In clinical practice, X-ray imaging is still an important examination performed not only to recognize the disorders, but also to provide a differential diagnosis. It helps estimate disease progression and is used to monitor the effects of treatment and the development of possible complications. Differential diagnosis of rheumatic diseases is performed on the basis of localization and type of radiographic changes. The surrounding periarticular soft tissues, bone structures, joint space, with special attention to articular bone surfaces and epiphyses, are analyzed. The aim of this work is to describe characteristic inflammatory changes present on X-ray imaging typical for the most commonly diagnosed rheumatic diseases in children, such as juvenile idiopathic arthritis, systemic lupus erythematosus, systemic scleroderma, mixed connective tissue disease, juvenile dermatomyositis, juvenile spondyloarthropathy and systemic vascular disease

    To review prevalence of rheumatic disorders in Sub-saharan Africa and in the context of current medical practice in the region assess the need for service and educational provision. Medline, (English, French). Pre-Medline literature review from the 1950's (Current contents). Various conference reports including attendance at all three AFLAR (African League Against Rheumatism) congresses in the 1990's. Author's personal database. All cited references read in full. The evidence shows rheumatoid arthritis and systemic lupus erythematosus to be increasing in frequency in the indigenous populations of East, Central and South Africa but remaining rare in West Africans. Gout is now more prevalent than ever throughout the subcontinent. HIV has spawned a variety of previously rare spondyloarthropathies (reactive arthritis, psoriatic arthritis, enthesopathy) and changed the epidemiology of pyomyositis and osteomyelitis. Osteoarthritis is a universal problem. Juvenile chronic arthritis is not rare and rheumatic fever is common. Acute and chronic locomotor problems associated with diverse entities such as leprosy, brucellosis, meningococcus, alpha viruses, parasites, fluorosis, rickets and haemoglobinopathies enhance diagnostic diversity and therapeutic and educational requirements. Suggestions made to address the challenge posed by the burden of rheumatic disorders.

  10. Immunoadsorption for collagen and rheumatic diseases.

    The field of therapeutics has seen remarkable progress in the recent years, which has made mainstream drug treatment possible for collagen and rheumatic diseases. However, treatment of intractable cases where drug effectiveness is poor is a challenge. Furthermore, organ damage, concurrent illnesses or allergic reactions make adequate drug therapy impossible. For such cases, therapeutic apheresis is very significant, and it is important how this should be valued related to drug therapies. Therapeutic apheresis for collagen and rheumatic diseases involves the removal of factors that cause and exacerbate the disease; the aim of immunoadsorption, in particular, is to improve the clinical condition of patients with autoimmune disease by selectively removing pathogenic immune complexes and autoantibodies from their plasma. Immunoadsorption, in particular, unlike plasma exchange and DFPP, utilizes a high-affinity column that selectively removes autoantibodies and immune complexes, leaving other plasma components intact. There is no need to replenish fresh frozen plasma or blood products such as albumin and gamma globulin preparations. Immunoadsorption is thus superior in terms of safety, as the risk of infection or allergic reaction relating to these preparations can be avoided. We anticipate future investigations of application of synchronized therapy using drugs and therapeutic apheresis, most notably immunoadsorption, in combination to treat intractable clinical conditions such as collagen and rheumatic diseases. In this paper, our discussion includes the indications for immunoadsorption such as collagen and rheumatic diseases, the relevant conditions and types, as well as the latest understanding related to methods and clinical efficacy.

    Full Text Available Cardiac tumors constitute 0.2% of all tumors. Primary cardiac tumors occur infrequently with an incidence of 0.0017-0.19% as shown by autopsies performed in non-selected populations. Among these tumors, cardiac myxomas are most commonly encountered, with left atrial myxomas being more prevalent than right atrial ones. The classic triad of symptoms, of which at least one is present in a patient with atrial myxoma, are obstructive traits including dyspnea and syncope, constitutional symptoms such as fever and anorexia, and thromboembolic events. Surgical resection confers almost definitive treatment with recurrence rates being as low as 3%. A 50-year-old woman referred to the Emergency Unit with a sudden episode of chest heaviness and shortness of breath. There was no significant physical examination finding and all routine lab investigations were normal. She underwent an angiography that revealed tight left anterior descending artery stenosis. An angioplasty was also performed, but she had an episode of presyncope immediately. Then, echocardiogram was performed that showed a large left atrial myxoma causing severe mitral regurgitation. Thus, urgent open heart surgery was planned. The myxoma was identified and excised, the mitral annulus resolved, and normal flow was restored. The patient was then discharged home and followed up for 2 months with no complaints. In the current study, we reported a rare case where mitral regurgitation was caused by a left atrial myxoma. Our report highlighted the diverse clinical spectrum of myxoma and emphasized the need for early echocardiographic diagnosis to aid in identification of myxoma followed by early surgical intervention.

    Blunt chest trauma is a very rare cause of valve disorder. Moreover, mitral valve involvement is less frequent than is aortic or tricuspid valve involvement, and the clinical course is usually acute. In the present report, we describe the case of a 49-year-old man with a perivalvular mitral injury that became clinically manifest one year after a violent, nonpenetrating chest injury. This case is atypical in regard to the valve involved (isolated mitral damage), the injury type (perivalvular leak in the absence of subvalvular abnormalities), and the clinical course (interval of one year between trauma and symptoms).

  14. Intracranial arterial stenosis.

    2014-04-01

    Intracranial arterial stenosis (IAS) is usually attributable to atherosclerosis and corresponds to the most common cause of stroke worldwide. It is very prevalent among African, Asian, and Hispanic populations. Advancing age, systolic hypertension, diabetes mellitus, high levels of low-density lipoprotein cholesterol, and metabolic syndrome are some of its major risk factors. IAS may be associated with transient or definite neurological symptoms or can be clinically asymptomatic. Transcranial Doppler and magnetic resonance angiography are the most frequently used ancillary examinations for screening and follow-up. Computed tomography angiography can either serve as a screening tool for the detection of IAS or increasingly as a confirmatory test approaching the diagnostic accuracy of catheter digital subtraction angiography, which is still considered the gold (confirmation) standard. The risk of stroke in patients with asymptomatic atherosclerotic IAS is low (up to 6% over a mean follow-up period of approximately 2 years), but the annual risk of stroke recurrence in the presence of a symptomatic stenosis may exceed 20% when the degree of luminal narrowing is 70% or more, recently after an ischemic event, and in women. It is a matter of controversy whether there is a specific type of treatment other than medical management (including aggressive control of vascular risk factors and antiplatelet therapy) that may alter the high risk of stroke recurrence among patients with symptomatic IAS. Endovascular treatment has been thought to be helpful in patients who fail to respond to medical treatment alone, but recent data contradict such expectation.

    Variable mortality rates have been reported for patients with rheumatic diseases admitted to an intensive care unit (ICU). Due to the absence of appropriate control groups in previous studies, it is not known whether the presence of a rheumatic disease constitutes a risk factor. Moreover, the accuracy of the Acute Physiology and Chronic Health Evaluation II (APACHE II) score for predicting outcome in this group of patients has been questioned. The primary goal of this study was to compare outcome of patients with rheumatic diseases admitted to a medical ICU to those of controls. The records of all patients admitted between 1 April 2003 and 30 June 2014 (n=4020) were screened for the presence of a rheumatic disease during admission (n=138). The diagnosis of a rheumatic disease was by standard criteria for these conditions. An age- and gender-matched control group of patients without a rheumatic disease was extracted from the patient population in the database during the same period (n=831). Mortality in ICU, in hospital and after 180 days did not differ significantly between patients with and without rheumatic diseases. There was no difference in the performance of the APACHE II score for predicting outcome in patients with rheumatic diseases and controls. This score, as well as a requirement for the use of inotropes or vasopressors, accurately predicted hospital mortality in the group of patients with rheumatic diseases. In conclusion, patients with a rheumatic condition admitted to intensive care do not do significantly worse than patients without such a disease.

    2016-01-01

    Full Text Available Piezogenic pedal papules (PPP are herniations of subcutaneous adipose tissue into the dermis. PPP are skin-colored to yellowish papules and nodules on lateral surfaces of feet that typically become apparent when the patient stands flat on his/her feet. Some connective tissue diseases and syndromes have been reported in association with PPP. Mitral valve prolapse (MVP is a myxomatous degeneration of the mitral valve, characterized by the displacement of an abnormally thickened mitral valve leaflet into the left atrium during systole. MVP may be isolated or part of a heritable connective tissue disorder. PPP, which is generally considered as an isolated lesion, might be also a predictor of some cardiac diseases associated with connective tissue abnormalities such as MVP. A detailed systemic investigation including cardiac examination should be done in patients with PPP. Since in the literature, there are no case reports of association of PPP with MVP, we report these cases.

    The morphology of the mitral valve apparatus was assessed on 100 normal left ventriculograms. Four distinct types of mitral valve were identified according to the position of the mitral fulcrum (the point of attachment of the leaflets to the annulus) and the configuration of the adjacent left ventricular wall (left ventricular fornix) during diastole. Types I and II closely simulated prolapse of the mitral valve (pseudoprolapse) in the right anterior oblique projection during the ejection period. Measurements showed that contraction of the ventricle failed to reduce the diameter of the mitral annulus in 26 per cent of normal left ventricles. (U.K.)

  18. The serpentine mitral valve and cerebral embolism

    2011-02-01

    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.

    We demonstrate the technical aspects of a novel adjustable mitral ring. This new ring was implanted in a female landrace pig, for training and educational purposes. It can be adjusted independently in the P1, P2 and P3 segments, if required, to treat  recurrent mitral regurgitation, and this is a key difference to comparable devices. The first-in-man implantation is anticipated in the near future. © The Author 2016. Published by MMCTS on behalf of the European Association for Cardio-Thoracic Surgery. All rights reserved.

    1981-05-01

    Mitral valve clicks with or without late systolic murmurs were detected in genetically unrelated marital partners of 5 families. The first family represented 2 successive nonconsanguineous marital unions with 3 generations of mitral valve clicks. The second family included 1 natural and 2 adopted children with clinical and echographic evidence of mitral valve prolapse. The third family was comprised of asymptomatic parents, both with nonejection clicks and mitral valve prolapse, whose daughter presented 3 years previously with syncope, palpitations, and combined mitral and tricuspid valve prolapse. The fourth family had 3 members with auscultatory and ultrasonic manifestations of billowing mitral valve, whereas the fourth member had "silent mitral valve prolapse." The fifth family represented a mother with auscultatory and echographic evidence of mitral valve prolapse; her 14-year-old daughter had both mitral and tricuspid valve prolapse, whereas the son had a bicuspid aortic valve. Both children were products of a prior marriage, and her husband has symptomatic mitral valve prolapse. We conclude that matrimonial mitral valve prolapse probably reflects the purported (6--10%) prevalence of this disorder in the general population. The consequences of such marital union on progeny is currently unclear and warrants future investigation.

    Osteoporosis in rheumatic diseases is a very well-known complication. Systemic inflammation results in both generalized and localized bone loss and erosions. Recently, increased knowledge of inflammatory process in rheumatic diseases has resulted in the development of potent inhibitors of the cytokines, the biologic DMARDs. These treatments reduce systemic inflammation and have some effect on the generalized and localized bone loss. Progression of bone erosion was slowed by TNF, IL-6 and IL-1 inhibitors, a JAK inhibitor, a CTLA4 agonist, and rituximab. Effects on bone mineral density varied between the biological DMARDs. Medications that are approved for the treatment of osteoporosis have been evaluated to prevent bone loss in rheumatic disease patients, including denosumab, cathepsin K, bisphosphonates, anti-sclerostin antibodies and parathyroid hormone (hPTH 1-34), and have some efficacy in both the prevention of systemic bone loss and reducing localized bone erosions. This article reviews the effects of biologic DMARDs on bone mass and erosions in patients with rheumatic diseases and trials of anti-osteoporotic medications in animal models and patients with rheumatic diseases.

    Patients with symptomatic severe aortic stenosis and severe mitral regurgitation or severe tricuspid regurgitation were excluded from the major transcatheter aortic valve replacement trials. We studied these 2 subgroups in patients at extreme risk for surgery in the prospective, nonrandomized, single-arm CoreValve US Expanded Use Study. The primary end point was all-cause mortality or major stroke at 1 year. A favorable medical benefit was defined as a Kansas City Cardiomyopathy Questionnaire overall summary score greater than 45 at 6 months and greater than 60 at 1 year and with a less than 10-point decrease from baseline. There were 53 patients in each group. Baseline characteristics for the severe mitral regurgitation and severe tricuspid regurgitation cohorts were age 84.2 ± 6.4 years and 84.9 ± 6.5 years; male, 29 (54.7%) and 22 (41.5%), and mean Society of Thoracic Surgeons score 9.9% ± 5.0% and 9.2% ± 4.0%, respectively. Improvement in valve regurgitation from baseline to 1 year occurred in 72.7% of the patients with severe mitral regurgitation and in 61.8% of patients with severe tricuspid regurgitation. A favorable medical benefit occurred in 31 of 47 patients (66.0%) with severe mitral regurgitation and 33 of 47 patients (70.2%) with severe tricuspid regurgitation at 6 months, and in 25 of 44 patients (56.8%) with severe mitral regurgitation and 24 of 45 patients (53.3%) with severe tricuspid regurgitation at 1 year. All-cause mortality or major stroke for the severe mitral regurgitation and severe tricuspid regurgitation cohorts were 11.3% and 3.8% at 30 days and 21.0% and 19.2% at 1 year, respectively. There were no major strokes in either group at 1 year. Transcatheter aortic valve replacement in patients with severe mitral regurgitation or severe tricuspid regurgitation is reasonable and safe and leads to improvement in atrioventricular valve regurgitation.

    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.

    Computed tomography (CT) of the temporomandibular joint (TMJ) was compared with hypocycloidal tomography in 30 joints of 15 adults with rheumatic disease. CT included 1.5 mm thick axial scans (at 1.0 mm intervals) with reformatted oblique sagittal and oblique coronal sections. Multisection (at 2.0 mm intervals) tomography included oblique sagittal and occasionally, oblique coronal sections. CT demonstrated bone abnormalities in 21 and tomography in 20 joints, indicating high agreement between the imaging modalities regarding number of abnormal TMJs. Bone structures were, however, better visualized by multiplanar CT due to superior contrast and spatial resolution particularly in the most lateral and medial parts of the joint, indicating superiority of CT for depicting subtle bony TMJ abnormalities in patients with rheumatic disease.

    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.

  9. Sexual and reproductive health in rheumatic disease.

    Family size is reduced among patients with rheumatic diseases. The causes for the low number of children are multifactorial and include impaired sexual function, decreased gonadal function, pregnancy loss, therapy and personal choices. Sexuality contributes to quality of life in patients with rheumatic disease, but is often ignored by health professionals. Both disease-related factors and psychological responses to chronic disease can impair sexual functioning. Toxic effects of anti-inflammatory and immunosuppressive drugs can induce transient or permanent gonadal failure in women and men. Furthermore, permanent infertility can be a consequence of treatment with cyclophosphamide, whereas transient infertility can be caused by NSAIDs in women and sulfasalazine in men. These adverse effects must be communicated to the patients, and measures to preserve fertility should be initiated before the start of gonadotoxic therapy. Management of patients of both genders should include regular family planning, effective treatment of high disease activity, sexual counselling, and, if necessary, infertility treatment.

    Rheumatic heart disease (RHD) is the largest cardiac cause of morbidity and mortality in the world's youth. Early detection of RHD through echocardiographic screening in asymptomatic children may identify an early stage of disease, when secondary prophylaxis has the greatest chance of stopping disease progression. Latent RHD signifies echocardiographic evidence of RHD with no known history of acute rheumatic fever and no clinical symptoms. Determine the prevalence of latent RHD among children ages 5-16 in Lilongwe, Malawi. This is a cross-sectional study in which children ages 5 through 16 were screened for RHD using echocardiography. Screening was conducted in 3 schools and surrounding communities in the Lilongwe district of Malawi between February and April 2014. Children were diagnosed as having no, borderline, or definite RHD as defined by World Heart Federation criteria. The primary reader completed offline reads of all studies. A second reader reviewed all of the studies diagnosed as RHD, plus a selection of normal studies. A third reader served as tiebreaker for discordant diagnoses. The distribution of results was compared between gender, location, and age categories using Fisher's exact test. The prevalence of latent RHD was 3.4% (95% CI = 2.45, 4.31), with 0.7% definite RHD and 2.7% borderline RHD. There was no significant differences in prevalence between gender (P = .44), site (P = .6), urban vs. peri-urban (P = .75), or age (P = .79). Of those with definite RHD, all were diagnosed because of pathologic mitral regurgitation (MR) and 2 morphologic features of the mitral valve. Of those with borderline RHD, most met the criteria by having pathological MR (92.3%). Malawi has a high rate of latent RHD, which is consistent with other results from sub-Saharan Africa. This study strongly supports the need for a RHD prevention and control program in Malawi. © 2016 Wiley Periodicals, Inc.

    To evaluate the relationship between resilience and clinical outcomes in patients with autoimmune rheumatic diseases. Focus groups, individual interviews, and chart reviews were done to collect data on 188 women with autoimmune rheumatic diseases, namely rheumatoid arthritis (n=51), systemic lupus erythematosus (n=70), systemic sclerosis (n=35), and Sjögren's syndrome (n=32). Demographic, clinical, and laboratory variables were assessed including disease activity by patient reported outcomes. Resilience was evaluated by using the Brief Resilience Scale. Bivariate, multiple linear regression, and classification and regression trees were used to analyse data. Resilience was influenced by age, duration of disease, and socioeconomic status. Lower resilience scores were observed in younger patients (50years) had higher resilience scores regardless of socioeconomic status. There was no influence of disease activity on resilience. A particular behaviour was observed in systemic sclerosis in which patients with high socioeconomic status and regular physical activity had higher resilience scores. Resilience in patients with autoimmune rheumatic diseases is a continuum process influenced by age and socioeconomic status. The ways in which these variables along with exercise influence resilience deserve further investigation. Copyright © 2017 Société française de rhumatologie. Published by Elsevier SAS.

  14. Neonatal aortic stenosis.

    Drury, Nigel E; Veldtman, Gruschen R; Benson, Lee N

    2005-09-01

    Neonatal aortic stenosis is a complex and heterogeneous condition, defined as left ventricular outflow tract obstruction at valvular level, presenting and often requiring treatment in the first month of life. Initial presentation may be catastrophic, necessitating hemodynamic, respiratory and metabolic resuscitation. Subsequent management is focused on maintaining systemic blood flow, either via a univentricular Norwood palliation or a biventricular route, in which the effective aortic valve area is increased by balloon dilation or surgical valvotomy. In infants with aortic annular hypoplasia but adequately sized left ventricle, the Ross-Konno procedure is also an attractive option. Outcomes after biventricular management have improved in recent years as a consequence of better patient selection, perioperative management and advances in catheter technology. Exciting new developments are likely to significantly modify the natural history of this disorder, including fetal intervention for the salvage of the hypoplastic left ventricle; 3D echocardiography providing better definition of valve morphology and aiding patient selection for a surgical or catheter-based intervention; and new transcutaneous approaches, such as duel beam echo, to perforate the valve.

    The study objective was to evaluate patients with Marfan syndrome and mitral valve regurgitation undergoing valve repair or replacement and to compare them with patients undergoing repair for myxomatous mitral valve disease. We reviewed the medical records of consecutive patients with Marfan syndrome treated surgically between March 17, 1960, and September 12, 2011, for mitral regurgitation and performed a subanalysis of those with repairs compared with case-matched patients with myxomatous mitral valve disease who had repairs (March 14, 1995, to July 5, 2013). Of 61 consecutive patients, 40 underwent mitral repair and 21 underwent mitral replacement (mean [standard deviation] age, 40 [18] vs 31 [19] years; P = .09). Concomitant aortic surgery was performed to a similar extent (repair, 45% [18/40] vs replacement, 43% [9/21]; P = .87). Ten-year survival was significantly better in patients with Marfan syndrome with mitral repair than in those with replacement (80% vs 41%; P = .01). Mitral reintervention did not differ between mitral repair and replacement (cumulative risk of reoperation, 27% vs 15%; P = .64). In the matched cohort, 10-year survival after repair was similar for patients with Marfan syndrome and myxomatous mitral disease (84% vs 78%; P = .63), as was cumulative risk of reoperation (17% vs 12%; P = .61). Patients with Marfan syndrome and mitral regurgitation have better survival with repair than with replacement. Survival and risk of reoperation for patients with Marfan syndrome were similar to those for patients with myxomatous mitral disease. These results support the use of mitral valve repair in patients with Marfan syndrome and moderate or more mitral regurgitation, including those having composite replacement of the aortic root.

    Patients with mitral valve prolapse and hyperthyroidism have common symptoms; the most outstanding symptom is palpitation. To determine whether or not common symptoms contributed to the reported association of these conditions, we evaluated 220 patients with symptomatic mitral valve prolapse and 216 first-degree relatives in 72 families; 65 relatives with mitral valve prolapse and 151 relatives without mitral valve prolapse, all greater than or equal to 16 years of age. Thirty subjects, aged 49 +/- 13 years (p less than 0.025 vs entire study group), had thyroid disease (23 subjects had definite thyroid disease, seven subjects had probable); 27 of 30 subjects with thyroid disease (90%) were female (p less than 0.005). The age- and sex-adjusted prevalence of hyperthyroidism was significantly higher in probands with mitral valve prolapse than in family members without mitral valve prolapse (3.5% vs 0%, p = 0.03), while an intermediate prevalence of hyperthyroidism (2.2%) was observed in family members with mitral valve prolapse. Thus, the prevalence of hyperthyroidism is increased among symptomatic patients with mitral valve prolapse as compared to family members without mitral valve prolapse, but the prevalence of thyroid conditions is similar among family members with or without this condition. These findings are explained by the effect of common symptoms on clinical detection of both mitral valve prolapse and hyperthyroidism.

  19. Immunomodulatory interplay of the microbiome and therapy of rheumatic diseases.

    2017-11-01

    Modulation of the immune system by microbes, especially from the gastrointestinal tract, is increasingly considered a key factor in the onset, course and outcome of rheumatic diseases. The interplay of the microbiome, along with genetic predisposition and environmental exposure, is thought to be an important trigger for rheumatic diseases. Improved identification of the relationship of disease-specific genetic alterations and rheumatic diseases has potential diagnostic and therapeutic applications. Treatment of rheumatic disorders is influenced by microbial actions but this interplay can be challenging due to variable and unpredictable responses to therapies. Expanded knowledge of the microbiome now allows clinicians to more precisely select ideal medication regimens and to predict response to and toxicity from drugs. Rheumatic diseases and associated therapies were among the earliest microbiome interactions investigated, yet it is notable that current research is focused on clinical and immunological associations but, in comparison, a limited number of studies regarding the microbiome's impact on treatment for rheumatic diseases have been published. In the coming years, further knowledge of immunomodulating interactions between the microbiome and the immune system will aid our understanding of autoimmunity and will be increasingly important in selection of therapeutic agents for patients with autoimmune and rheumatic diseases. In this review, recent literature regarding the bidirectional immunomodulatory effects of the microbiome with rheumatic diseases and current understanding and gaps regarding the drug-microbiome interface in the management of these disorders is presented.

    Autoimmune liver diseases (ALDs) are known to be associated with systemic autoimmune rheumatic diseases (SARDs) and their autoantibodies. We aimed to study the prevalence of SARDs and related autoantibodies, as well as their prognostic implications in a group of patients with ALDs. This was a cross-sectional study. Sixty patients with ALDs (38.3% with autoimmune hepatitis; 11.7% with primary biliary cirrhosis; 25% with primary sclerosing cholangitis and 25% with overlap syndrome) were studied for the presence of SARDs and their autoantibodies. There was autoimmune rheumatic disease in 20% of the studied sample. Systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) were the commonest (11.6% and 5%, respectively). Antinuclear antibodies (ANAs) were present in 35% of the patients, followed by anti-Ro (20.0%); anti-nucleosome (18.3%); rheumatoid factor (10%) anti-CCP (8.3%); anti-RNP (8.3%); anti-ds-DNA (6.6%); anti-La (3.3%); anti-Sm (3.3%), anti-ribosomal P (3.3%). Anti-Ro (p = 0.0004), anti-La (p = 0.03), anti-RNP (p = 0.04) and anti-Sm (p = 0.03) were commonly found in patients with SARD, but not anti-DNA, anti-nucleosome and anti-ribosomal P. No differences were found in liver function tests regarding to the presence of autoantibodies. There was a high prevalence of SARD and their autoantibodies in ALD patients. Anti-Ro, anti-La, anti-RNP and anti-Sm positivity points to an association with systemic autoimmune rheumatic diseases. The presence of autoantibodies was not related to liver function tests.

    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.

    Because mitral valve dysfunction in adults with Marfan syndrome is poorly characterized, this study compares mitral valve pathophysiology and morphology with that of myxomatous mitral disease, documents types of mitral valve operations, and assesses long-term survival and durability of mitral valve surgery in Marfan patients. From May 1975 to June 2000, 27 adults with Marfan syndrome underwent mitral valve surgery. Their valve pathophysiology and morphology was compared with that of 119 patients with myxomatous mitral disease undergoing surgery from September 1995 to March 1999. Survival and repair durability were assessed at follow-up. Compared with myxomatous disease patients, Marfan patients had less posterior leaflet prolapse (44% versus 70%, p = 0.01), more bileaflet (44% versus 28%, p = 0.09) and anterior leaflet prolapse (11% versus 3%, p = 0.07), and presented earlier for surgery (age 41 +/- 12 years versus 57 +/- 13, p Marfan patients had longer and thinner leaflets. Mitral valve repair was performed less frequently in Marfan (16 of 27, 59%) than myxomatous disease patients (112 of 119, 94%). There were no hospital deaths; at 10 years, survival was 80% and freedom from reoperation 96%, with only 1 reoperation among the 16 repairs. Mitral valve pathophysiology and morphology differ between Marfan and myxomatous mitral valve diseases. Valve repair in Marfan patients is durable and gives acceptable long-term results, even in adults who present with advanced mitral valve pathology. With increasing use of the modified David reimplantation operation and sparing of the aortic valve, mitral valve repair is a greater imperative, particularly since we have not had to reoperate on any Marfan patients with reimplantations.

    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.

    Systemic rheumatic diseases have significant morbidity and mortality, due in large part to concurrent infections. The lung has been reported among the most frequent sites of infection in patients with rheumatic disease, who are susceptible to developing pneumonia sustained both by common pathogens and by opportunistic microorganisms. Patients with rheumatic disease show a peculiar vulnerability to infectious complications. This is due in part to intrinsic disease-related immune dysregulation and in part to the immunosuppressive treatments. Several therapeutic agents have been associated to a wide spectrum of infections, complicating the management of rheumatic diseases. This review discusses the most frequent pulmonary infections encountered in rheumatic diseases, focusing on opportunistic agents, consequent diagnostic challenges and appropriate therapeutic strategies.

    The leaflets of the mitral valve interact with the mitral jet and significantly impact diastolic flow patterns, but the effect of mitral valve morphology and kinematics on diastolic flow and its implications for left ventricular function have not been clearly delineated. In the present study, we employ computational hemodynamic simulations to understand the effect of mitral valve leaflets on diastolic flow. A computational model of the left ventricle is constructed based on a high-resolution contrast computed-tomography scan, and a physiological inspired model of the mitral valve leaflets is synthesized from morphological and echocardiographic data. Simulations are performed with a diode type valve model as well as the physiological mitral valve model in order to delineate the effect of mitral-valve leaflets on the intraventricular flow. The study suggests that a normal physiological mitral valve promotes the formation of a circulatory (or “looped”) flow pattern in the ventricle. The mitral valve leaflets also increase the strength of the apical flow, thereby enhancing apical washout and mixing of ventricular blood. The implications of these findings on ventricular function as well as ventricular flow models are discussed

    2002-01-01

    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.

    Full Text Available A 76-day-old infant weighing 3.4 kg was referred for surgical intervention for severe mitral valve stenoinsufficiency caused by leaflet fibrosis and calcification. He had experienced a cerebral infarction in the left middle cerebral artery territory, which was deemed attributable to an embolism of a calcified particle from the dysmorphic mitral valve. Because mitral valve replacement using a prosthetic valve was not feasible in this small baby, mitral valve replacement with a pulmonary autograft was performed. After a brief period of extracorporeal membrane oxygenation (ECMO support, he was weaned from ECMO and was discharged home without further cardiovascular complications.

    Central airway stenosis is benign or malignant etiology. Multidiscplinary approach is useful in treatment central airway stenosis. In inoperable cases, interventional bronchology is good therapeutic alternative. We can use NdYAG laser, argon plasma coagulation, elektrocautery, cryotherapy, photodynamic therapy and stents for obstruction release. In malignant stenosis, we combine often methods of the interventional bronchology with brachytherapy, chemotherapy and external radiotherapy. (author)

    Staphylococcus caprae is a rare cause of infective endocarditis. Here, we report a case involving the native mitral valve in the absence of an implantable cardiac electronic device. A 76-year-old man presented with a 2 week history of confusion and pyrexia. His past medical history included an open reduction and internal fixation of a humeral fracture 17 years previously, which remained non-united despite further revision 4 years later. There was no history of immunocompromise or farm-animal contact. Two sets of blood culture bottles, more than 12 h apart, were positive for S. caprae . Trans-thoracic echocardiography revealed a 1×1.2 cm vegetation on the mitral valve, with moderate mitral regurgitation. Due to ongoing confusion, he had a magnetic resonance imaging brain scan, which showed a subacute small vessel infarct consistent with a thromboembolic source. A humeral SPECT-CT (single-photon emission computerized tomography-computerized tomography) scan showed no clear evidence of acute osteomyelitis. Surgical vegetectomy and mitral-valve repair were considered to reduce the risk of further systemic embolism and progressive valve infection. However, the potential risks of surgery to this patient led to a decision to pursue a cure with antibiotic therapy alone. He remained well 3 months after discharge, with repeat echocardiography demonstrating a reduction in the size of the vegetation (0.9 cm). Management of this infection was challenging due to its rarity and its unclear progression, complicated by the dilemma surrounding surgical intervention in a patient with a complex medical background.

    Adoption of robotic mitral valve surgery has been slow, likely in part because of its perceived technical complexity and a poorly understood learning curve. We sought to correlate changes in technical performance and outcome with surgeon experience in the "learning curve" part of our series. From 2006 to 2011, two surgeons undertook robotically assisted mitral valve repair in 458 patients (intent-to-treat); 404 procedures were completed entirely robotically (as-treated). Learning curves were constructed by modeling surgical sequence number semiparametrically with flexible penalized spline smoothing best-fit curves. Operative efficiency, reflecting technical performance, improved for (1) operating room time for case 1 to cases 200 (early experience) and 400 (later experience), from 414 to 364 to 321 minutes (12% and 22% decrease, respectively), (2) cardiopulmonary bypass time, from 148 to 102 to 91 minutes (31% and 39% decrease), and (3) myocardial ischemic time, from 119 to 75 to 68 minutes (37% and 43% decrease). Composite postoperative complications, reflecting safety, decreased from 17% to 6% to 2% (63% and 85% decrease). Intensive care unit stay decreased from 32 to 28 to 24 hours (13% and 25% decrease). Postoperative stay fell from 5.2 to 4.5 to 3.8 days (13% and 27% decrease). There were no in-hospital deaths. Predischarge mitral regurgitation of less than 2+, reflecting effectiveness, was achieved in 395 (97.8%), without correlation to experience; return-to-work times did not change substantially with experience. Technical efficiency of robotic mitral valve repair improves with experience and permits its safe and effective conduct.

    Full Text Available Caseous calcification of the mitral annulus (CCMA is a rare variant of mitral annular calcification. It comprises a combination of calcium, fatty acids, and cholesterol, and is characterized by heterogeneity in echocardiographic images, with peripheral areas of calcification surrounding a central area of echolucency, resembling a periannular mass. Here, we describe a case of CCMA combined with a mitral annulus abscess, manifesting as a waving, horn-like structure. Although the image characteristics of the posterior mitral annulus suggested CCMA, additional findings warranted further work-up and studies.

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.

    Vitiligo is a chronic disease characterized by the dysfunction or destruction of melanocytes with secondary depigmentation. The aim of the present study was to determine the prevalence of vitiligo associated with autoimmune rheumatic diseases. The clinical records from a 10-year database of patients with rheumatic diseases and associated vitiligo was analysed, with one group of patients having autoimmune rheumatic disease and another non-autoimmune rheumatic disease. Available serum samples were used to assess the anti-melanocyte antibodies. A total of 5,251 individual clinical files were archived in the last 10 years, and these patients underwent multiple rheumatology consultations, with 0.3% of the group presenting with vitiligo. The prevalence of vitiligo in the autoimmune rheumatic disease group was 0.672%, which was mainly associated with lupus and arthritis. However, patients with more than one autoimmune disease had an increased relative risk to develop vitiligo, and anti-melanocyte antibodies were positive in 92% of these patients. By contrast, the prevalence was 0.082% in the group that lacked autoimmune rheumatic disease and had negative autoantibodies. In conclusion, the association between vitiligo and autoimmune rheumatic diseases was relatively low. However, the relative risk increased when there were other autoimmune comorbidities, such as thyroiditis or celiac disease. Therefore, the presence of multiple autoimmune syndromes should be suspected.

    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

    Streptococcus pyogenes is a human-specific and globally prominent bacterial pathogen that despite causing numerous human infections, this bacterium is normally found in an asymptomatic carrier state. This review provides an overview of both bacterial and human factors that likely play an important role in nasopharyngeal colonization and pharyngitis, as well as the development of acute rheumatic fever and rheumatic heart disease. Here we highlight a recently described role for bacterial superantigens in promoting acute nasopharyngeal infection, and discuss how these immune system activating toxins could be crucial to initiate the autoimmune process in rheumatic heart disease.

    2018-02-28

    Ischemic mitral regurgitation occurs relatively frequently in patients with coronary artery disease and is associated with an increased long term risk. The pathophysiology of ischemic mitral regurgitation is vexing, and poses both diagnostic and therapeutic challenges, leading to the need for a comprehensive, multidisciplinary approach. The management is largely focused on medical therapy, and for those eligible, coronary revascularization and/or cardiac resynchronization therapy may be considered. In select patients, mitral valve surgery or catheter-based therapy may be undertaken with careful consideration of the underlying pathophysiology, surgical risk, and expected long-term outcomes. The appropriate evaluation of patients with ischemic mitral regurgitation involves a careful multidisciplinary approach that carefully considers symptomatology, the etiology and severity of the mitral regurgitation, as well as the assessment of comorbidities and operative risk to individualize the care of these patients.

    Ischemic mitral regurgitation is associated with a substantial risk of death. Practice guidelines recommend surgery for patients with a severe form of this condition but acknowledge that the supporting evidence for repair or replacement is limited. We randomly assigned 251 patients with severe ischemic mitral regurgitation to undergo either mitral-valve repair or chordal-sparing replacement in order to evaluate efficacy and safety. The primary end point was the left ventricular end-systolic volume index (LVESVI) at 12 months, as assessed with the use of a Wilcoxon rank-sum test in which deaths were categorized below the lowest LVESVI rank. At 12 months, the mean LVESVI among surviving patients was 54.6±25.0 ml per square meter of body-surface area in the repair group and 60.7±31.5 ml per square meter in the replacement group (mean change from baseline, -6.6 and -6.8 ml per square meter, respectively). The rate of death was 14.3% in the repair group and 17.6% in the replacement group (hazard ratio with repair, 0.79; 95% confidence interval, 0.42 to 1.47; P=0.45 by the log-rank test). There was no significant between-group difference in LVESVI after adjustment for death (z score, 1.33; P=0.18). The rate of moderate or severe recurrence of mitral regurgitation at 12 months was higher in the repair group than in the replacement group (32.6% vs. 2.3%, P<0.001). There were no significant between-group differences in the rate of a composite of major adverse cardiac or cerebrovascular events, in functional status, or in quality of life at 12 months. We observed no significant difference in left ventricular reverse remodeling or survival at 12 months between patients who underwent mitral-valve repair and those who underwent mitral-valve replacement. Replacement provided a more durable correction of mitral regurgitation, but there was no significant between-group difference in clinical outcomes.

  8. Refractory Rheumatic Disorder: Atypical Postpregnancy Osteoporosis

    2015-01-01

    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.

    An increasing number of experimental beating heart animal studies describe simple transapical mitral valve repairs based on the direct endoscopic visualization of the left ventricle. The aim of our human cadaveric study was to develop a method for more complex transapical endoscopic procedures by on-pump heart operations. After preparation of 20 human fresh cadavers, a standard left anterolateral minithoracotomy was performed in the fifth intercostal space and the pericardium was entered. A rigid 0 degree endoscope and the instruments were introduced through a silicon apical port. To restore the natural form of the left heart, CO2 was insufflated. To test the mitral valve competence, the left ventricle was pressure-injected with saline after each step. After transecting the chords of the A2 segment of the anterior mitral leaflet before the experimental mitral valve repair, the tendinous chord was replaced using an especially designed clip chord. The second part of the experiment consisted of a segmental excision of the P2 segment of the posterior mitral leaflet followed by a standard valvuloplasty and suture annuloplasty. With the help of the described transapical endoscopic mitral valve repair technique, we gained direct visual information of the coaptation line of the mitral leaflets as well as the anatomy and function of the subvalvular apparatus. Using intracardiac imaging, we could perform successful transapical complex mitral repair in each case. The minimally invasive transapical endoscopic method has the potential to offer advantages for on-pump mitral valve repair procedures even in complex mitral valve repair cases.

    An independent association between gout and coronary artery disease is well established. The relationship between gout and valvular heart disease, however, is unclear. The aim of this study was to assess the association between gout and aortic stenosis. We performed a retrospective case-control study. Aortic stenosis cases were identified through a review of outpatient transthoracic echocardiography (TTE) reports. Age-matched controls were randomly selected from patients who had undergone TTE and did not have aortic stenosis. Charts were reviewed to identify diagnoses of gout and the earliest dates of gout and aortic stenosis diagnosis. Among 1085 patients who underwent TTE, 112 aortic stenosis cases were identified. Cases and nonaortic stenosis controls (n = 224) were similar in age and cardiovascular comorbidities. A history of gout was present in 21.4% (n = 24) of aortic stenosis subjects compared with 12.5% (n = 28) of controls (unadjusted odds ratio 1.90, 95% confidence interval 1.05-3.48, P = .038). Multivariate analysis retained significance only for gout (adjusted odds ratio 2.08, 95% confidence interval 1.00-4.32, P = .049). Among subjects with aortic stenosis and gout, gout diagnosis preceded aortic stenosis diagnosis by 5.8 ± 1.6 years. The age at onset of aortic stenosis was similar among patients with and without gout (78.7 ± 1.8 vs 75.8 ± 1.0 years old, P = .16). Aortic stenosis patients had a markedly higher prevalence of precedent gout than age-matched controls. Whether gout is a marker of, or a risk factor for, the development of aortic stenosis remains uncertain. Studies investigating the potential role of gout in the pathophysiology of aortic stenosis are warranted and could have therapeutic implications. Published by Elsevier Inc.

    Rectal stenosis is a common condition caused by a wide variety of diseases, including both intrinsic and extrinsic disorders, as well as both malignant and benign pathologies. Barium enema, CT, and MRI are the primary modalities for the evaluation of the disease, and careful observation of the characteristic radiologic features usually leads to correct diagnosis. However, some of the lesions looks very similar and are difficult to differentiate from each other. The purpose of this study is to review the literature on diseases that cause rectal stenosis, to clarify the characteristics of radiologic features, and to suggest the limitations in differential diagnosis. Deliberate analysis of these imaging features and correlation with clinical manifestations can facilitate a more specific diagnosis. (orig.)

    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.

    To evaluate the clinical associations between rheumatic fever and antiphospholipid syndrome and the impact of coexistence of these two diseases in an individual. Systematic review in electronics databases, regarding the period from 1983 to 2012. The keywords: "Rheumatic Fever," "Antiphospholipid Syndrome," and "Antiphospholipid Antibody Syndrome" are used. were identified 11 cases described in the literature about the association of rheumatic fever and antiphospholipid syndrome. Clinical presentation of rheumatic fever was characterized by the predominance of carditis (11/11) and chorea (7/11). Regarding the manifestations of APS, the stroke was observed in 7/11 (63.6%), with one of them having probable embolic origin. The present study brings the information that the association between APS and RF is quite rare, however, is of great clinical importance. Doctors who deal with the RF should include in their differential diagnosis the APS, especially in the presence of stroke in patients with RF and whose echocardiogram does not show intracavitary thrombi.

    At a center where surgeons favor mitral valve (MV) repair for all subsets of leaflet prolapse, we compared results of patients undergoing repair for simple versus complex degenerative MV disease. From January 1985 to January 2016, 6153 patients underwent primary isolated MV repair for degenerative disease, 3101 patients underwent primary isolated MV repair for simple disease (posterior prolapse), and 3052 patients underwent primary isolated MV repair for complex disease (anterior or bileaflet prolapse), based on preoperative echocardiographic images. Logistic regression analysis was used to generate propensity scores for risk-adjusted comparisons (n = 2065 matched pairs). Durability was assessed by longitudinal recurrence of mitral regurgitation and reoperation. Compared with patients with simple disease, those undergoing repair of complex pathology were more likely to be younger and female (both P values < .0001) but with similar symptoms (P = .3). The most common repair technique was ring/band annuloplasty (3055/99% simple vs 3000/98% complex; P = .5), followed by leaflet resection (2802/90% simple vs 2249/74% complex; P < .0001). Among propensity-matched patients, recurrence of severe mitral regurgitation 10 years after repair was 6.2% for simple pathology versus 11% for complex pathology (P = .007), reoperation at 18 years was 6.3% for simple pathology versus 11% for complex pathology, and 20-year survival was 62% for simple pathology versus 61% for complex pathology (P = .6). Early surgical intervention has become more common in patients with degenerative MV disease, regardless of valve prolapse complexity or symptom status. Valve repair was associated with similarly low operative risk and time-related survival but less durability in complex disease. Lifelong annual echocardiographic surveillance after MV repair is recommended, particularly in patients with complex disease. Copyright © 2018 The American Association for Thoracic Surgery

    Minimal access mitral valve surgery (MVS) has already proved to be feasible and effective with low perioperative mortality and excellent long-term outcomes. However, experience in more complex valve diseases such as infective endocarditis (IE) still remains limited. The aim of this retrospective study was to evaluate early and long-term results of minimal access MVS for IE. Data were entered into a dedicated database. Analysis was performed retrospectively for the 8-year period between January 2007 and April 2015. During the study period, 35 consecutive patients underwent minimal access MVS for IE at our department. Twenty-four had diagnosis of native MV endocarditis (68.6%) and 11 of mitral prosthesis endocarditis (31.4%).Thirty patients underwent early MVS (85.7%), and 5 patients were operated after the completion of antibiotic treatment (14.3%). Seven patients underwent MV repair (20%), 17 patients underwent MV replacement (48.6%), and 11 patients underwent mitral prosthesis replacement (31.4%). Thirty-day mortality was 11.4% (4 patients). No neurological or vascular complications were reported. One patient underwent reoperation for prosthesis IE relapse after 37 days. Overall actuarial survival rate at 1 and 5 years was 83%; freedom from MV reoperation and/or recurrence of IE at 1 and 5 years was 97%. Minimally invasive MVS for IE is feasible and associated with good early and long-term results. Preoperative accurate patient selection and transoesophageal echocardiography evaluation is mandatory for surgical planning. © The Author 2017.

    One of the reasons why use of Doppler echocardiography is growing rapidly is because of its utility in detecting the presence of valvular stenosis and in estimating its severity. Detection of the presence of stenotic valvular heart disease using Doppler echocardiography was originally described over 10 years ago. It has been demonstrated that Doppler blood velocity data could be used to estimate the severity of a stenotic lesion. This chapter discusses the evaluation of valvular stenois using Doppler

    Marfan syndrome is a multisystemic genetic condition affecting connective tissue. It carries a reduced life expectancy, largely dependent on cardiovascular complications. More common cardiac manifestations such as aortic dissection and aortic valve incompetence have been widely documented in the literature. Mitral valve prolapse (MVP), however, has remained poorly documented. This article aims at exploring the existing literature on the pathophysiology and diagnosis of MVP in patients with Marfan syndrome, defining its current management and outlining the future developments surrounding it. © 2017 Wiley Periodicals, Inc.

    To estimate the prevalence of rheumatic diseases in Lebanon and to explore their distribution by geographic location, age, and gender.   Using the Community Oriented Program for the Control of Rheumatic Diseases (COPCORD) methodology, a random sample of 3530 individuals aged 15 and above was interviewed from the six Lebanese governorates. Positive respondents were evaluated by rheumatologists using the internationally accepted classification criterion of the American College of Rheumatology for the diagnosis of rheumatic diseases. Prevalence rates of current and past musculoskeletal problems were 24.4% and 8.4%, respectively. Shoulder (14.3%), knee (14.2%) and back (13.6%) were the most common pain sites. Point prevalence of rheumatic diseases was 15.0%. The most frequent types of rheumatic diseases were of mechanical origin, namely soft tissue rheumatism (5.8%) and osteoarthritis (4.0%). Rheumatoid arthritis (1.0%) and spondylathropathies (0.3%) constituted the most common inflammatory diseases. Coastal areas had the lowest prevalence of all diseases except for fibromyalgia. All diseases showed an increasing prevalence pattern with age and a higher prevalence among women than men. This is the first study to give population-based estimates of rheumatic diseases in Lebanon. The high burden calls for public health attention for early detection, control and prevention of these conditions. Point prevalence of individual diseases was within the range of results from other COPCORD surveys with some variations that can be attributed to differences in methodology and geo-ethnic factors. © 2011 The Authors.

    Present review aimed to provide a comprehensive documentation of plants used as anti-rheumatic ethnomedicines in Pakistan and to suggest future recommendations. Data on anti-rheumatic plants was collected from published scientific papers, reports and thesis using online searching engines such as Google Scholar PubMed and Science Direct. Five distinct zones in the country were classified on the basis of geography, humidity and rainfall. We used Sorenson similarity index for plants and their parts used between different zones. A total of 137 anti-rheumatic plant species representing 55 families and 104 genera are used in Pakistan. Herbs (87 plants) were the primary source of anti-rheumatic medicinal plants, while leaves (22 % plant species) were the most frequently used part in the preparation of ethnomedicinal recipes. Highest number of 52 medicinal plant species were found in Zone A having high mountains and cold climate where the prevalence of rheumatism was more common. Solanum surattense was found with highest conservation concerns as it was using in 13 different areas against rheumatism. Results of Sorenson index revealed that there is a similarity of plants and its parts uses between different zones. In conclusions, geography and climate have an important role in causing rheumatic disease. Pakistan has a number of anti-rheumatic plants that are used by the local populations through their traditional knowledge. Moreover, inter zonal similarities among plants and its part uses indicate higher pharmacological potency of these medicinal plants. Further, the review will also provide an insight regarding the conservation status of reported plants. (author)

    To assess the incidence of acute Rheumatic Fever (ARF). A retrospective, descriptive, observational study on the first attack and recurrence was performed in a general hospital and a reference center. By Jones criteria: 67 cases, 39 women and 28 men; 58% first attack, 42% recurrence. Higher incidence during spring-winter. The most common major criteria were: carditis, polyarthritis. The most common minor criteria were: fever, arthralgias and acute phase reaction markers. No differences between hospitals were noted. Evidence of contact with streptococcus was found. Mitral, aortic and tricuspid valves were commonly affected. Incidence in the age group > 5 < 20 was 7/1000. Incidence of ARF has decreased, but has not been eradicated. It occurs in developing countries, where it remains an issue of public health. Failures in clinical suspicion, prophylaxis, and adherence to treatment influence this situation. Education for health, early diagnosis, and primary and secondary prophylaxis should be reinforced.

    Full Text Available A middle-aged patient of Greenlandic origin was referred for skin infection of the leg. An initial minor trauma of the skin of the distal right lower extremity was complicated by bullous erysipelas which cultured positive for group A β-hemolytic streptococci (GABHS. The clinical condition deteriorated and necrotizing fasciitis developed despite relevant surgical and antibiotic treatment. Approximately 3 weeks later, the patient developed arthralgia, impaired renal function with azotemia, hypertension and severe nephrotic syndrome with periorbital and peripheral edema. A kidney biopsy demonstrated endocapillary glomerulonephritis. Concomitantly, carditis with chest pain, moderately reduced left ventricular ejection fraction and mitral regurgitation were noted. The patient had no signs of pharyngitis in the whole period. The patient thus contracted poststreptococ glomerulonephritis and furthermore she fulfilled the criteria of acute rheumatic fever following a GABHS skin infection. We suggest a possible relation between a virulent GABHS clone causing NF and ARF.

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.

    Mitral valve repair for myxomatous Barlow disease is a challenging procedure requiring complex surgery with less than optimal results. The use of ring-only repair has been previously reported but never analyzed or followed-up. We investigated this simple valve repair approach for patients with Barlow disease and multisegment involvement causing mainly central jet. Of 572 patients who underwent mitral valve repair for mitral regurgitation at our medical center, 24 with Barlow disease (aged 47 ± 14 years; 46% male) underwent ring-only repair. Patients were characterized by severely enlarged mitral valve annulus, multisegment prolapse involving both leaflets, and demonstrated mainly a central wide regurgitant jet. Surgical technique included only the implantation of a large mitral annuloplasty ring. Early and late outcome results were compared with those of the remaining patients who underwent conventional mitral valve repair for degenerative disease (controls). All ring-only patients presented with moderate-severe/severe mitral regurgitation (vena contracta, 0.6 ± 0.1 cm; regurgitation volume, 52 ± 17 mL), with mainly a central jet and almost preserved ejection fraction (59% ± 6%). Cardiopulmonary bypass and crossclamp times were significantly shorter compared with controls (P Barlow disease patients with multisegment involvement and mainly central regurgitant jet is both simple and reproducible with excellent late outcomes.

    The chordal structure is a part of mitral valve geometry that has been commonly neglected or simplified in computational modeling due to its complexity. However, these simplifications cannot be used when investigating the roles of individual chordae tendineae in mitral valve closure. For the first time, advancements in imaging, computational techniques, and hardware technology make it possible to create models of the mitral valve without simplifications to its complex geometry, and to quickly run validated computer simulations that more realistically capture its function. Such simulations can then be used for a detailed analysis of chordae-related diseases. In this work, a comprehensive model of a subject-specific mitral valve with detailed chordal structure is used to analyze the distinct role played by individual chordae in closure of the mitral valve leaflets. Mitral closure was simulated for 51 possible chordal rupture points. Resultant regurgitant orifice area and strain change in the chordae at the papillary muscle tips were then calculated to examine the role of each ruptured chorda in the mitral valve closure. For certain subclassifications of chordae, regurgitant orifice area was found to trend positively with ruptured chordal diameter, and strain changes correlated negatively with regurgitant orifice area. Further advancements in clinical imaging modalities, coupled with the next generation of computational techniques will enable more physiologically realistic simulations.

    2012-02-01

    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.

    Conclusion: Right anterolateral mini-thoracotomy minimally invasive technique provides excellent exposure of the mitral valve, even with a small atrium and offers a better cosmetic lateral scar which is less prone to keloid formation. In addition, minimally invasive right anterolateral mini-thoracotomy is as safe as median sternotomy for mitral valve surgery, with fewer complications and postoperative pain, less ICU and hospital stay, fast recovery to work with no movement restriction after surgery. It should be used as an initial approach for mitral valve surgery. Furthermore, it was believed that less spreading of the incision, no interference with the diaphragm and less tissue dissection might improve outcomes, particularly respiratory function.

    Percutaneous mitral valve (MV) repair has been performed in over 20,000 patients worldwide. As clinical experience in this technique grows indications for its use are being defined. Mitral regurgitation (MR) encompasses a complex heterogeneous group and its treatment is governed by determining a clear understanding of the underlying aetiology. Surgical MV repair remains the gold standard therapy for severe MR. However in select groups of high-risk surgical patients, a percutaneous approach to MV repair is establishing its role. This review gives an overview of the published data in percutaneous MV repair and its impact on the contemporary management of MR. Published by the BMJ Publishing Group Limited.

    Patients with autoimmune thyroid diseases (ATD) such as Graves' disease (GD) and Hashimoto thyroiditis (HT) may have non-organ specific autoantibodies such as ANA (antinuclear antibodies) and RF (rheumatoid factor). To study the prevalence of rheumatic autoantibodies in a group of ATD patients without known rheumatic diseases and to evaluate its association with the patients' epidemiological and treatment profile. To follow positive non-organ specific autoantibody-positive ATD individuals to investigate whether they will develop a rheumatic disorder. A sample of 154 ATD patients (70 HT and 84 GD; mean age 45.3 ± 14.2) had determination of ANA by immunofluorescence, using hep-2 cells as substrate, extractable nuclear antigen (ENA) profile by ELISA kits and RF by latex agglutination. Epidemiological and treatment profile were obtained through chart review. These patients were followed for the mean period of five years, between 2010 to 2015. Positive ANA was found in 17.5% (27/154) of the patients: anti-Ro/SS-A in 4/154 (2.5%); anti-RNP in 4/154 (2.5%) and anti-La/SS-B in 3/154 (1.9%). None had anti-Sm antibodies. RF was detected in 12/154 (7.7%) of ATD patients and was more common in older individuals (p = 0.007). There was a positive association between the presence of RF and ANA (p = 0.03; OR = 3.89; 95% CI = 1.1-13.3). None of the patients with positive autoantibodies developed clinical rheumatic diseases during the period of observation. We found rheumatic autoantibodies in 17.5% of ATD patients without rheumatic diseases. None of them were associated with the appearance of clinical rheumatic disorder during the period of five years. ©2018The Author(s). Published by S. Karger AG, Basel.

    Full Text Available Objective: To analyze the results of surgical correction of patients with tricuspid pathology in rheumatic multi-valvular heart disease. Methods: We retrospectively analyzed outcomes of surgical correction of tricuspid valve disease in 292 patients with rheumatic multi-valvular heart defects, who underwent surgery in our clinic. Results: The age of our patients ranged from 12 to 74 years (mean age 36.7 (9.4 years, among them 197 (67.4% women and 95 (32.6% - men. According to the degree of circulatory disorders, 21 (7.2% patients were in NYHA class III and 271 (92.8% patients - class IV. Of them 235 (80.5% patients were operated by the method of De Vega using plastic fibrous ring. After tricuspid valve (TV and fibrous ring repair in 26.9% - tricuspid regurgitation disappeared, in 62.8% - regurgitation decreased to the 1st degree, and the remaining 10.3% of patients had 2nd (moderate degree tricuspid regurgitation. In 7 (2.38% cases of infective endocarditis, the "open heart surgery" correction – replacement of TV with biological prosthesis was made. Creation of the bicuspid tricuspid valve techniques was used in 13.4% of cases. Conclusion: Our study demonstrated that correction of tricuspid valve disease in our cohort of patients, including valve repair and replacement and reconstructive surgery of fibrous ring alone or in combination with mitral or aortic valve replacement/ repair is accompanied by reduction of tricuspid regurgitation and reduction of cardiac chamber size and right ventricular pressure. No complications intrinsic to operative technique of tricuspid valve reconstructive surgery as advanced atrioventricular block or myocardial ischemia and infarction were recorded.

    This paper evaluates patients with cervical spinal canal compromise due to congenital anomalies (achondroplasia, Chiari malformation) and degenerative diseases using MR cord motion and cerebrospinal fluid (CSF) flow studies. Pulsatile longitudinal motion of the cervical cord was determined by means of cardiac-gated velocity phase contrast methods, including cine. Pathology included dwarfism (n = 15), Chiari malformation (n = 10), spondylosis (n = 10), and acute cord compression (n = 9). Symptomatic cases of congenital cervical stenosis had decreased cord motion, although CSF flow was not always significantly compromised. Postoperative cases demonstrated good cord and CSF motion, unless compression or obstruction was present

    Biplane left ventricular cineangiographies in 4 patients with typical obstructive idiopathic hypertrophic subaortic stenosis (IHSS) and in control patients with normal left ventricles were analysed. In the protruding hypertrophic muscular interventricular septum of IHSS a markedly reduced shortening occurs in either direction during the systolic contraction. It does not bend towards the right ventricle. It is suggested that the septum of IHSS acts as a suspender during the systolic contraction, thereby accounting for the fast stroke volume ejection and the high ejection fraction of IHSS. (Auth.)

The most frequent masks of RD were kidney (78% and osteoarticular system (64% lesions, vascular disorders (36%, peripheral polyneuropathies (36%, and enlarged salivary glands with xerostomia (28.5%. Serum and urine immunochemical study should be performed in all patients who have clinical manifestations of seropositive RA, spondyloarthritis, intensive bone pain syndrome, ulceronecrotic vasculitis, enlarged submandibular salivary glands with macroglossia in the absence of markers of autoimmune disease for the timely diagnosis of PCD and the exclusion of RD. The paper estimates the sensitivity and specificity of main methods used to diagnose different types of PCD.

    Rheumatic diseases can be categorized by pathology into several specific types of musculoskeletal problems, including synovitis (e.g. rheumatoid arthritis), enthesopathy (e.g. ankylosing spondylitis) and cartilage degeneration (e.g. osteoarthritis). Skeletal radiographs have contributed to the diagnosis of these articular diseases, and some disease entities need typical radiographic changes as a factor of the diagnostic criteria. However, they sometimes show normal radiographic findings in the early stage of disease, when there is demineralization of less than 30-50%. Bone scans have also been used in arthritis, but not widely because the findings are nonspecific and it is thought that bone scans do not add significant information to routine radiography. Bone scans do however play a different role than simple radiography, and it is a complementary imaging method in the course of management of arthritis. The image quality of bone scans can be improved by obtaining regional views and images under al pin-hole collimator, and through a variety of scintigraphic techniques including the three phase bone scan and bone SPECT. Therefore, bone scans could improve the diagnostic value, and answer multiple clinical questions, based on the pathophysiology of various forms of arthritis

    This paper aims to explore the assessment of patients with rheumatologic diseases, especially rheumatoid arthritis (RA), before undergoing orthopedic surgery. Perioperative assessment ensures an early diagnosis of the patient's medical condition, overall health, medical co-morbidities, and the assessment of the risk factors associated with the proposed procedures. Perioperative assessment allows for proper postoperative management of complications and of the management of drugs such as disease-modifying anti-rheumatic drugs (DMARD) and anti-platelets, and corticosteroids. The assessment also supports follow up plans, and patient education. Perioperative assessment enables the discussion of the proposed treatment plans and the factors associated with them in each case among the different specialists involved to facilitate an appropriate early decision-making about the assessment and treatment of patients with rheumatologic diseases. It also enables the discussion of both condition and procedure with the patient to ensure a good postoperative care. The article identifies the components of perioperative medical evaluation, discusses perioperative management of co-morbidities and the management of specific clinical problems related to RA, systemic lupus erythematosus, the management of DMARDs, like methotrexate (MTX) and biologic therapies, prophylactic antibiotics, and postoperative follow up, including patient education and rehabilitation PMID:24062860

    Gingivitis and periodontitis are immunoinflammatory periodontal diseases characterized by chronic localized infections usually associated with insidious inflammation This narrative review discusses periodontal diseases and mechanisms influencing the immune response and autoimmunity in pediatric rheumatic diseases (PRD), particularly juvenile idiopathic arthritis (JIA), childhood-onset systemic lupus erythematosus (C-SLE) and juvenile dermatomyositis (JDM). Gingivitis was more frequently observed in these diseases compared to health controls, whereas periodontitis was a rare finding. In JIA patients, gingivitis and periodontitis were related to mechanical factors, chronic arthritis with functional disability, dysregulation of the immunoinflammatory response, diet and drugs, mainly corticosteroids and cyclosporine. In C-SLE, gingivitis was associated with longer disease period, high doses of corticosteroids, B-cell hyperactivation and immunoglobulin G elevation. There are scarce data on periodontal diseases in JDM population, and a unique gingival pattern, characterized by gingival erythema, capillary dilation and bush-loop formation, was observed in active patients. In conclusion, gingivitis was the most common periodontal disease in PRD. The observed association with disease activity reinforces the need for future studies to determine if resolution of this complication will influence disease course or severity.

    William's syndrome, in order to more completely delineate the total spectrum of the disorder, indicates that 'infantile hypercalcemia', 'peculiar facies' and 'supravalvular aortic stenosis.' In has other many vascular anomalies, such as peripheral pulmonary arterial stenosis, coronary arterial stenosis, celiac arterial stenosis, and renal aterial stenosis. Only 32% of the patients have evidence of supravalvular aortic stenosis. And it is very rare disease entity that has been reported rarely in Korea. Recently authors experienced a case that was questioned William's syndrome with peripheral pulmonary arterial stenosis, clinically and preliminary radiologically and this case was confirmed by operation. Here we report a case of William's syndrome with peripheral pulmonary arterial stenosis and reviewed literatures

    2003-01-01

    An 81-year-old woman was evaluated for prosthetic mitral valve function. She had received a Harken disk mitral valve 29 years earlier due to severe mitral valve disease. This particular valve prosthesis is known for premature disk edge wear and erosion. The patient's 2-dimensional Doppler echocardiogram showed the distinctive appearance of a disk mitral valve prosthesis. Color Doppler in diastole showed a unique crown appearance, with initial flow acceleration around the disk followed by convergence to laminar flow in the left ventricle. Cineradiographic imaging revealed normal valve function and minimal disk erosion. We believe this to be the longest reported follow-up of a surviving patient with a rare Harken disk valve. We present images with unique echocardiographic and cineangiographic features. (Tex Heart Inst J 2003;30:319–21) PMID:14677746

    Several autoimmune diseases have familial aggregation and possibly, common genetic predispositions. In a large population-based study, we evaluated if children born to mothers with SLE have an increased risk of rheumatic and non-rheumatic autoimmune diseases, versus children born to mothers without SLE. Using the "Offspring of SLE mothers Registry (OSLER)", we identified children born live to SLE mothers and their matched controls, and ascertained autoimmune diseases based on ≥1 hospitalization or ≥2 physician visits with a relevant diagnostic code. We adjusted for maternal age, education, race/ethnicity, obstetrical complications, calendar birth year, and sex of child. 509 women with SLE had 719 children, while 5824 matched controls had 8493 children. Mean follow-up was 9.1 (SD 5.8) years. Children born to mothers with SLE had similar frequency of rheumatic autoimmune diagnoses (0.14%, 95% CI 0.01, 0.90) versus controls (0.19%, 95% CI 0.11, 0.32). There was a trend towards more non-rheumatic autoimmune diseases in SLE offspring (1.11%, 95% CI 0.52, 2.27) versus controls (0.48%, 95% CI 0.35, 0.66). In multivariate analyses, we did not see a clear increase in rheumatic autoimmune disease (OR 0.71, 95% CI 0.11-4.82) but children born to mothers with SLE had a substantially increased risk of non-rheumatic autoimmune disease versus controls (OR 2.30, 95% CI 1.06-5.03). Although the vast majority of offspring have no autoimmune disease, children born to women with SLE may have an increased risk of non-rheumatic autoimmune diseases, versus controls. Additional studies assessing offspring through to adulthood would be additionally enlightening. This article is protected by copyright. All rights reserved. This article is protected by copyright.

    WB-MRI in rheumatic diseases is still an emerging imaging tool. So far, WB-MRI in rheumatism is mainly used in seronegative spondyloarthropathies. In these diseases it has the ability to visualize the majority of involved joints and soft tissue structures (both active inflammatory changes and chronic structural abnormalities) in one examination, making it suitable for imaging of different forms of spondylopathies, allowing different types of joint involvement to be recognized and assessing both the acute symptoms of disease and the longer-term consequences. Its role in daily practice is not yet clear. WB-MRI is not recommended as a first line investigation in every patient suffering from a form of spondyloarthropathy, but may add important information in difficult cases. Moreover, WB-MRI might obtain a stronger role in the early diagnosis of spondyloarthritides and in the assessment of treatment response. Other rheumatic diseases where WB-MRI may play a role in the future are polymyositis/dermatomyositis, CRMO and certain forms of systemic vasculitis. WB-MRI in rheumatism is a promising tool with great potential, however further systematic evaluation of its abilities and limitations in different forms of rheumatic diseases is awaited.

    Arthritis and Rheumatism International (ARi), founded in 1988, is an association of national lay organizations comprising mainly people whose lives are affected by arthritis and rheumatism. ARi's charter defines the organization's aims, including to raise awareness of the needs of people with arthritis/rheumatism, to improve the quality of their lives through education and self-management programs, and to support research into causes, management, prevention, and cure of arthritis. With the aid of a grant from the Pfizer Foundation in 2002, ARi has been able to further develop into a strong organization throughout the world, with a membership of 22 countries. Successful intitiatives include the People with Arthritis and Rheumatism in Europe Manifesto, which has served as a very effective focus for developing action plans, opening dialogues, building partnerships with other organizations, lobbying governments, and gaining media attention throughout Europe. The manifesto (website: www.PAREmanifesto.org) was developed by ARi working in conjunction with The International Organisation of Youth with Rheumatism and the EULAR Social League. These are examples of initiatives that ARi aims to promote on a global scale in the next few years.

  19. Role of inflammasomes in inflammatory autoimmune rheumatic diseases.

    Science.gov (United States)

    Yi, Young-Su

    2018-01-01

    Inflammasomes are intracellular multiprotein complexes that coordinate anti-pathogenic host defense during inflammatory responses in myeloid cells, especially macrophages. Inflammasome activation leads to activation of caspase-1, resulting in the induction of pyroptosis and the secretion of pro-inflammatory cytokines including interleukin (IL)-1β and IL-18. Although the inflammatory response is an innate host defense mechanism, chronic inflammation is the main cause of rheumatic diseases, such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), ankylosing spondylitis (AS), and Sjögren's syndrome (SS). Since rheumatic diseases are inflammatory/autoimmune disorders, it is reasonable to hypothesize that inflammasomes activated during the inflammatory response play a pivotal role in development and progression of these diseases. Indeed, previous studies have provided important observations that inflammasomes are actively involved in the pathogenesis of inflammatory/autoimmune rheumatic diseases. In this review, we summarize the current knowledge on several types of inflammasomes during macrophage-mediated inflammatory responses and discuss recent research regarding the role of inflammasomes in the pathogenesis of inflammatory/autoimmune rheumatic diseases. This avenue of research could provide new insights for the development of promising therapeutics to treat inflammatory/autoimmune rheumatic diseases.

  20. Protecting Bone Health in Pediatric Rheumatic Diseases: Pharmacological Considerations.

    Science.gov (United States)

    Zhang, Yujuan; Milojevic, Diana

    2017-06-01

    Bone health in children with rheumatic conditions may be compromised due to several factors related to the inflammatory disease state, delayed puberty, altered life style, including decreased physical activities, sun avoidance, suboptimal calcium and vitamin D intake, and medical treatments, mainly glucocorticoids and possibly some disease-modifying anti-rheumatic drugs. Low bone density or even fragility fractures could be asymptomatic; therefore, children with diseases of high inflammatory load, such as systemic onset juvenile idiopathic arthritis, juvenile dermatomyositis, systemic lupus erythematosus, and those requiring chronic glucocorticoids may benefit from routine screening of bone health. Most commonly used assessment tools are laboratory testing including serum 25-OH-vitamin D measurement and bone mineral density measurement by a variety of methods, dual-energy X-ray absorptiometry as the most widely used. Early disease control, use of steroid-sparing medications such as disease-modifying anti-rheumatic drugs and biologics, supplemental vitamin D and calcium, and promotion of weight-bearing physical activities can help optimize bone health. Additional treatment options for osteoporosis such as bisphosphonates are still controversial in children with chronic rheumatic diseases, especially those with decreased bone density without fragility fractures. This article reviews common risk factors leading to compromised bone health in children with chronic rheumatic diseases and discusses the general approach to prevention and treatment of bone fragility.

    Full Text Available Prosthetic Valve Obstruction (PVO is a serious complication which is associated with increased morbidity and mortality. This could result from thrombus formation, development of pannus, or a combination of both. Patients with this complication often present with symptoms and signs of heart failure, systemic embolism, acute cardiovascular collapse, and sudden death. Transesophageal echocardiography and cine fluoroscopy play a vital role in diagnosis of this potentially lethal condition. Herein, we reported a 56-year-old male patient who presented with severe heart failure and was found to have obstructed ATS27 bileaflet mitral prosthetic valve. Thrombolysis and redo surgery are two important options for treating this condition although guidelines for choosing between the two are not very definite.

    Renal Artery Stenosis (RAS), is one of the causes of secondary hypertension; there are many causes of renal artery stenosis, as atherosclerosis of the renal artery which account for 90% of cases of RAS; fibromuscular dysplasia accounts for 10% of RAS. Various causes of thrombophilia either due congenital causes or acquired causes and can lead to RAS. Our patient was presented by acute attack of epistaxis and hypertension. Angiography of the Renal Arteries,are showed no sign of renal artery stenosis. However, the right kidney showed upper pole infarction, and the left kidney showed evidence of functional lower pole renal artery stenosis, although there is no anatomical stenosis detected in angiography. Work up for the cause of thrombophilia did not help in the diagnosis, which may be due to an undiscovered cause of thrombophilia

    A case of leaflet fracture and embolization of a mitral prosthetic valve is described. A 54-year-old man had received mitral valve replacement with an Edwards-Duromedics 29M prosthetic valve, at 10 years ago. Emergency mitral valve replacement was performed because the patient had severe congestive left heart failure with severe acute mitral regurgitation caused by a fracture in one of the mitral valve leaflets. The leaflet, which was fractured into 2 pieces, was removed from the right common iliac artery at 3 months after valve replacement. Visual inspection revealed that the leaflet contained a midline fracture. The fracture originated within a cavitary erosion pit near the major radius of the leaflet. The patient recovered from acute renal failure, requiring hemodialysis for 80 days, and is currently without complaints. We have used a Duromedics mitral valve in 11 patients, from April 1987 to April 1988. No subsequent valve failure has occurred. The diagnosis, treatment and cause of a mechanical valve fracture are discussed.

  5. Role of Imaging Techniques in Percutaneous Treatment of Mitral Regurgitation.

    2016-04-01

    Mitral regurgitation is the most prevalent valvular heart disease in the United States and the second most prevalent in Europe. Patients with severe mitral regurgitation have a poor prognosis with medical therapy once they become symptomatic or develop signs of significant cardiac dysfunction. However, as many as half of these patients are inoperable because of advanced age, ventricular dysfunction, or other comorbidities. Studies have shown that surgery increases survival in patients with organic mitral regurgitation due to valve prolapse but has no clinical benefit in those with functional mitral regurgitation. In this scenario, percutaneous repair for mitral regurgitation in native valves provides alternative management of valvular heart disease in patients at high surgical risk. Percutaneous repair for mitral regurgitation is a growing field that relies heavily on imaging techniques to diagnose functional anatomy and guide repair procedures.

    The seven pillars of governance established by the National Health Service in the United Kingdom provide a useful framework for the process of introducing new procedures to a hospital. Drawing from local experience, the author present guidance for institutions considering establishing a minimal access mitral valve program. The seven pillars of governance apply to the practice of minimally invasive mitral valve surgery, based on the principle of patient-centred practice. The author delineate the benefits of minimally invasive mitral valve surgery in terms of: "clinical effectiveness", including reduced length of hospital stay, "risk management effectiveness", including conversion to sternotomy and aortic dissection, "patient experience" including improved cosmesis and quicker recovery, and the effectiveness of communication, resources and strategies in the implementation of minimally invasive mitral valve surgery. Finally, the author have identified seven learning curves experienced by surgeons involved in introducing a minimal access mitral valve program. The learning curves are defined as: techniques of mitral valve repair, Transoesophageal Echocardiography-guided cannulation, incisions, instruments, visualization, aortic occlusion and cardiopulmonary bypass strategies. From local experience, the author provide advice on how to reduce the learning curves, such as practising with the specialised instruments and visualization techniques during sternotomy cases. Underpinning the NHS pillars are the principles of systems awareness, teamwork, communication, ownership and leadership, all of which are paramount to performing any surgery but more so with minimal access surgery, as will be highlighted throughout this paper.

    There is no doubt that the various rheumatoid diseases constitute a socio-medical and socio-economic problem of first order. Surely the importance of this problem will even grow till around the turn of the millenium because the share of older people in the total population of the German Federal Republic is continuing to increase. Concerning frequency and duration the rheumatoid diseases figure at the top of all the insurance benefits. The following measures are essentials to a successful combat of this popular disease: Purposive information, prevention, early diagnosis, adequate treatment and a fitting the patient back into the productive process. Among the rheumatoid diseases the degenerative changes are ranking foremost in the range of frequency, unchallenged and at a considerable distance from the primarily inflammatory diseases. Arthroses and spondyloses are by no means a simple "articular detrition" but a disease in which the time factor is not always of decisive importance. There are ascertainable degenerative articular changes to be found in every person virtually by the age of fifty-five although not everybody has physical complaints. As to the increase in frequency observed in the past few years regarding fillings of applications for therapies because of so-called rheumatic complaints, changes of the conditions at someone's workplace alone cannot be blamed for it at all, rather bad posture and unsound stresses in one's leisure time as well as a new kind of consciousness of being sick supervene. A prophylactic healthful conduct depends strongly upon a person's social status and upon socio-cultural conditions.(ABSTRACT TRUNCATED AT 250 WORDS)

    The gynecologist's role in the management of rheumatic patients is complex: it includes the prevention of damage caused by drugs, the counseling about contraception to avoid pregnancy while taking teratogen drugs, the scheduling of pregnancy during the quiescent phase of the specific disease, the replacement of teratogen drugs and a competent management of the pregnancy. The task is carried out as part of a multidisciplinary team with a focus on the differential diagnosis between specific complications of pregnancy and the complications of the rheumatic disease. This is the right way to allow a conscious reproduction, with reduced risks and acceptable maternal-fetal outcomes, to this kind of patients considered at high risk.

    Human genetic diversity is the result of population genetic forces. This genetic variation influences disease risk and contributes to health disparities. Natural selection is an important influence on human genetic variation. Because immune and inflammatory function genes are enriched for signals of positive selection, the prevalence of rheumatic disease-risk alleles seen in different populations is partially the result of differing selective pressures (eg, due to pathogens).

    Hip joint abnormalities are commonly encountered in patients with rheumatic disorders. Although conventional radiography remains the mainstay for diagnosis of joint damage and subsequent follow-up, magnetic resonance imaging and, to a lesser extent, ultrasound have afforded the ability to detect early signs of articular involvement (i.e., synovitis and bone erosions), and to assess disease activity in treated patients. In more advanced stages of rheumatic disorders, magnetic resonance imaging and ultrasound are both useful in assessing paraarticular involvement (i.e., bursitis and synovial cysts)

    This paper reviews the influence of atmospheric factors on rheumatic diseases - rheumatoid arthritis, unspecified arthritis, gout, and systemic lupus erythematosis (SLE). The authors state that there appears to be ample evidence to conclude that various atmospheric factors do exert a significant impact on some people with various rheumatic diseases. The data are, however, crude relative to the authors general understanding. They recommend as a logical progression of research the determination of the effects of the meteorological/atmospheric factors of concern on the specific intrinsic mediators of inflammation.

    Double outlet right ventricle associated with atrioventricular concordance, pulmonary stenosis and situs solitus of the atria is a subset of double outlet right ventricle related through the surgical treatment. From 1974 to 1985, 14 patients, 5 males, 9 females (mean age 8.9 years, range 13 months-22 years) were operated upon. All patients had infundibular stenosis and normal or large pulmonary arteries. The apex of the heart was to the right in 2 patients, the right and left ventricles were superior and inferior in 2 patients and 1 patient had both anomalies. The ventricular septal defect was subaortic in 11 patients (aorto-mitral discontinuity in 5) and non-committed in 3 patients. Three patients had 2 ventricular septal defects. The aorta was anterior in 3 patients and to the right of the pulmonary artery in 11 patients. All patients, through a transventricular and transatrial approach, had a reconstructive surgery. In 3 patients, an aortic homograft valved conduit was used. One patient had the ventricular septal defect enlarged. There was one early death (7.1%) from high residual right ventricle pressure and no late death. One patient had a transient atrioventricular block. One patient was reoperated upon for a residual ventricular septal defect. All survivors had a good clinical result. Re-evaluation in 8 patients confirmed excellent haemodynamics: the right ventricle to pulmonary artery pressure gradient decreased from 80 mm Hg (range 60-95) preoperatively to 24 mm Hg (range 3-32) postoperatively.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Any site in the upper airway can get obstructed and cause noisy breathing as well as dyspnea. These include nasal causes such as choanal atresia or nasal stenosis; pharyngeal causes including lingual thyroid; laryngeal causes such as laryngomalacia; tracheobronchial causes such as tracheal stenosis; and subglottic stenosis. Lesions in the oropharynx may cause stertor, while lesions in the laryngotracheal tree will cause stridor. Subglottic stenosis is the third leading cause of congenital stridors in the neonate. Subglottic Stenosis presents challenges to the anesthesiologist. Therefore, It is imperative to perform a detailed history, physical examination, and characterization of the extent and severity of stenosis. Rigid endoscopy is essential for the preoperative planning of any of the surgical procedures that can be used for correction. Choice of operation is dependent on the surgeon′s comfort, postoperative capabilities, and severity of disease. For high-grade stenosis, single-stage laryngotracheal resection or cricotracheal resection are the best options. It has to be borne in mind that the goal of surgery is to allow for an adequate airway for normal activity without the need for tracheostomy. Anesthesia for airway surgery could be conducted safely with either sevofl uraneor propofol-based total intravenous anesthesia.

    2010-09-01

    Degenerative lumbosacral stenosis (DLSS) is the most common disorder of the caudal lumbar spine in dogs. This article reviews the management of this disorder and highlights the most important new findings of the last decade. Dogs with DLSS are typically neuro-orthopedic patients and can be presented with varying clinical signs, of which the most consistent is lumbosacral pain. Due to the availability of advanced imaging techniques such as computed tomography and magnetic resonance imaging that allow visualization of intervertebral disc degeneration, cauda equina compression, and nerve root entrapment, tailor-made treatments can be adopted for the individual patient. Current therapies include conservative treatment, decompressive surgery, and fixation-fusion of the L7-S1 junction. New insight into the biomechanics and pathobiology of DLSS and developments in minimally invasive surgical techniques will influence treatment options in the near future. Copyright 2010 Elsevier Inc.

    Full Text Available   Introduction: Tracheal stenosis is normally caused by trauma, infection, benign and malignant tumors, prolonged intubation or tracheostomy. The best treatment for tracheal stenosis is resection and anastomosis of trachea. Yet the major surgical complication of tracheal surgery is postoperative stenosis. The goal of this paper is to study the result of tracheal stenting as a replacement therapy for patients suffering from tracheal stenosis who are not good candidates for surgery.   Materials and Methods: This study presents the results of stenting in patients with: Inoperable tumoral stenosis,Non-tumoral stenosis being complicated due to prior surgeries,Inability to undergo a major surgery.The study was performed between September 2002 and July 2011 and poly flex stents were used by means of rigid bronchoscopy. Results: A total of 25 patients received stents during this study. Among them 15 patients suffered from benign and 10 suffered from malignant tracheal stenosis. The patients were followed up for at most 12 months after the stenting operation. The mean age of the patients was 35 years. The most common cause of stenosis was prolonged intubation (75%. The most common indication for stenting was the history of multiple tracheal operations. The most common complication of stenting and cause of stent removal was formation of granulation tissue. 30% of patients with benign tracheal stenosis were cured and about 10% improved until they could stand a major operation. Ten patients in benign group and 2 patients in malignant group (20% needed T-Tube insertion after stent removal but other patientcure by stenting. Conclusions: In benign cases stenting is associated with recurrence of symptoms which requires other therapeutic techniqus, so the stenting may not be named as a final solution in benign cases. However, this technique is the only method with approved efficacy for malignant cases with indication.

    An important proportion of patients with aortic stenosis (AS) have a 'low-gradient' AS, i.e. a small aortic valve area (AVA gradient (gradient discrepancy raises uncertainty about the actual stenosis severity and thus about the indication for aortic valve replacement (AVR) if the patient has symptoms and/or left ventricular (LV) systolic dysfunction. The most frequent cause of low-gradient (LG) AS is the presence of a low LV outflow state, which may occur with reduced left ventricular ejection fraction (LVEF), i.e. classical low-flow, low-gradient (LF-LG), or preserved LVEF, i.e. paradoxical LF-LG. Furthermore, a substantial proportion of patients with AS may have a normal-flow, low-gradient (NF-LG) AS: i.e. a small AVA-low-gradient combination but with a normal flow. One of the most important clinical challenges in these three categories of patients with LG AS (classical LF-LG, paradoxical LF-LG, and NF-LG) is to differentiate a true-severe AS that generally benefits from AVR vs. a pseudo-severe AS that should be managed conservatively. A low-dose dobutamine stress echocardiography may be used for this purpose in patients with classical LF-LG AS, whereas aortic valve calcium scoring by multi-detector computed tomography is the preferred modality in those with paradoxical LF-LG or NF-LG AS. Although patients with LF-LG severe AS have worse outcomes than those with high-gradient AS following AVR, they nonetheless display an important survival benefit with this intervention. Some studies suggest that transcatheter AVR may be superior to surgical AVR in patients with LF-LG AS. Published on behalf of the European Society of Cardiology.

    Carotid artery stenosis sometimes occurs after cervical radiotherapy. We report a 70-year-old woman with a history of radiotherapy for thyroid cancer at the age of 28 years. She had no signs and symptoms except the skin lesion at the irradiation site. Duplex ultrasonography revealed heterogeneous plaques showing 50% stenosis of bilateral common carotid arteries. Those lesions were observed within segment of irradiation, where atheromatous plaque usually seldom occurs. These indicated that the carotid stenosis was induced by radiotherapy. Although the efficacy of antiplatelet therapy for radiation-induced plaque is not clear, the plaques remained unchanged for 4 years in spite of aspirin administration. (author)

    Objectives To better understand the natural history and spectrum of fetal aortic stenosis (AS), we aimed to 1) determine the prenatal diagnosis rate of neonates with critical AS and a biventricular (BV) outcome; and 2) describe the findings at fetal echocardiography in prenatally diagnosed patients. Methods A multi-center, retrospective study was performed from 2000 to 2013. Neonates with critical AS who were discharged with a BV outcome were included. The prenatal diagnosis rate was compared to that reported for hypoplastic left heart syndrome (HLHS). Fetal echocardiographic findings in prenatally diagnosed patients were reviewed. Results Only 10 of 117 neonates (8.5%) with critical AS and a BV outcome were diagnosed prenatally, a rate significantly lower than that for HLHS in the contemporary era (82%; p<0.0001). Of the 10 patients diagnosed prenatally, all developed LV dysfunction by a median gestational age of 33 weeks (range, 28–35). When present, Doppler abnormalities such as retrograde flow in the aortic arch (n=2), monophasic mitral inflow (n=2), and left to right flow across the foramen ovale (n=8) developed late in gestation (median 33 weeks). Conclusion The prenatal diagnosis rate among neonates with critical AS and a BV outcome is very low, likely due to a relatively normal 4-chamber view in mid-gestation with development of significant obstruction in the 3rd trimester. This natural history contrasts with that of severe mid-gestation AS with evolving HLHS and suggests that the timing in gestation of significant AS has an important impact on subsequent left heart growth in utero.

    Human illnesses affect men and women differently. In some cases (diseases of sex organs, diseases resulting from X or Y chromosome mutations), reasons for sex discrepancy are obvious, but in other cases no reason is apparent. Explanations for sex discrepancy of illness occur at different biological levels: molecular (e.g., imprinting, X-inactivation), cellular (sex-specific receptor activity), organ (endocrine influences), whole organism (size, age), and environmental-behavioral, including intrauterine influences. Autoimmunity represents a prototypical class of illness that has high female-to-male (F/M) ratios. Although the F/M ratios in autoimmune diseases are usually attributed to the influence of estrogenic hormones, evidence demonstrates that the attributed ratios are imprecise and that definitions and classifications of autoimmune diseases vary, rendering at least part of the counting imprecise. In addition, many studies on sex discrepancy of human disease fail to distinguish between disease incidence and disease severity. In April 2001, the Institute of Medicine of the National Academy of Sciences published Exploring the Biological Contributions to Human Health: Does Sex Matter? (Wizemann T and Pardue M-L, editors). This minireview summarizes the section of that report that concerns autoimmune and infectious disease. Some thyroid, rheumatic, and hepatic autoimmune diseases have high F/M ratios, whereas others have low. Those that have high ratios occur primarily in young adulthood. Gonadal hormones, if they play a role, likely do so through a threshold or permissive mechanism. Examples of sex differences that could be caused by environmental exposure, X inactivation, imprinting, X or Y chromosome genetic modulators, and intrauterine influences are presented as alternate, theoretical, and largely unexplored explanations for sex differences of incidence. The epidemiology of autoimmune diseases (young, female) suggests that an explanation for sex discrepancy of

    Various autoimmune rheumatic diseases (ARDs), including rheumatoid arthritis, spondyloarthritis, vasculitis and systemic lupus erythematosus, are associated with premature atherosclerosis. However, premature atherosclerosis has not been uniformly observed in systemic sclerosis. Furthermore, although experimental models of atherosclerosis support the role of antiphospholipid antibodies in atherosclerosis, there is no clear evidence of premature atherosclerosis in antiphospholipid syndrome (APA). Ischemic events in APA are more likely to be caused by pro-thrombotic state than by enhanced atherosclerosis. Cardiovascular disease (CVD) in ARDs is caused by traditional and non-traditional risk factors. Besides other factors, inflammation and immunologic abnormalities, the quantity and quality of lipoproteins, hypertension, insulin resistance/hyperglycemia, obesity and underweight, presence of platelets bearing complement protein C4d, reduced number and function of endothelial progenitor cells, apoptosis of endothelial cells, epigenetic mechanisms, renal disease, periodontal disease, depression, hyperuricemia, hypothyroidism, sleep apnea and vitamin D deficiency may contribute to the premature CVD. Although most research has focused on systemic inflammation, vascular inflammation may play a crucial role in the premature CVD in ARDs. It may be involved in the development and destabilization of both atherosclerotic lesions and of aortic aneurysms (a known complication of ARDs). Inflammation in subintimal vascular and perivascular layers appears to frequently occur in CVD, with a higher frequency in ARD than in non-ARD patients. It is possible that this inflammation is caused by infections and/or autoimmunity, which might have consequences for treatment. Importantly, drugs targeting immunologic factors participating in the subintimal inflammation (e.g., T- and B-cells) might have a protective effect on CVD. Interestingly, vasa vasorum and cardiovascular adipose tissue may

    Barlow disease is a still challenging pathology for the surgeon. Aim of the present study is to report anatomic abnormalities of mitral valve in patients undergoing mitral valve repair. Between January 1st, 2007, and December 31st, 2010, 85 consecutive patients (54 men and 31 women, mean age 59 +/- 14 years--range: 28-85 years) with the features of a Barlow mitral valve disease underwent mitral repair Forty seven percent of patients were in New York Heart Association functional class III or IV. Preoperative transesophageal echocardiography was compared with anatomical findings at the moment of surgery. Transthoracic echocardiography diagnosis of Barlow disease according to the criteria described by Carpentier was confirmed at anatomical inspection. Annular calcifications were found in 28 patients while 7 patients presented single or multiple clefts. A flail posterior mitral leaflet was detected in 32 subjects, while a flail anterior leaflet in 8. Elongation of chordae tendineae was demonstrated in 45 patients and chordal rupture in 31. All patients showed at trans esophageal echocardiography the typical features of Barlow disease. Seventy-seven (90.6%) patients had severe mitral valve regurgitation, in the remaining 9.4% it was moderate to severe. Transesophageal echocardiography failed to identify clefts in 2/7 and chordal rupture in 4/31. bileaflet prolapse > 2 mm, billowing valve with excess tissue and thickened leaflets > or = 3 mm, and severe annular dilatation, are characteristics of Barlow disease, however the identification of the associated and complex abnormalities of mitral valve is necessary to obtain optimal valve repair.

    Tricuspid regurgitation (TR) often accompanies ischemic mitral regurgitation and is generally assumed to be a secondary consequence of altered hemodynamics of the left-sided regurgitation. We hypothesized that it may also be a direct consequence of right-sided ischemic disease. Therefore, our objectives were to (1) characterize the nature of this TR and (2) describe its time course after mitral valve surgery for ischemic mitral regurgitation, with or without concomitant tricuspid valve repair. From 2001 to 2011, 568 patients with ischemic mitral regurgitation underwent mitral valve surgery. They had varying degrees of TR and altered right-side heart morphology and function; 131 had concomitant tricuspid valve repair. Postoperatively, 1,395 echocardiograms were available to assess residual and recurrent TR. Greater severity of preoperative TR was accompanied by larger tricuspid valve diameter, greater leaflet tethering, worse right ventricular function, and higher right ventricular pressure (all p [trend] ≤ 0.002). Without tricuspid valve repair, 31% of patients with no preoperative TR had moderate or greater TR by 5 years, as did 62% with moderate TR. With tricuspid valve repair, 25% with moderate preoperative TR remained in that grade at 5 years, but 11% had severe TR. Tricuspid regurgitation accompanying ischemic mitral regurgitation is associated with right-side heart remodeling and dysfunction often mirroring that occurring in the left side of the heart-ischemic TR. Tricuspid valve repair is effective initially, but as with mitral valve repair, TR progressively returns. Therefore, when the severity of TR and right-sided remodeling reaches the point of irreversibility, it may be an indication to eliminate the TR by replacing the tricuspid valve.

  11. New insights into the epigenetics of inflammatory rheumatic diseases.

    2017-10-01

    Over the past decade, awareness of the importance of epigenetic alterations in the pathogenesis of rheumatic diseases has grown in parallel with a general recognition of the fundamental role of epigenetics in the regulation of gene expression. Large-scale efforts to generate genome-wide maps of epigenetic modifications in different cell types, as well as in physiological and pathological contexts, illustrate the increasing recognition of the relevance of epigenetics. To date, although several reports have demonstrated the occurrence of epigenetic alterations in a wide range of inflammatory rheumatic conditions, epigenomic information is rarely used in a clinical setting. By contrast, several epigenetic biomarkers and treatments are currently in use for personalized therapies in patients with cancer. This Review highlights advances from the past 5 years in the field of epigenetics and their application to inflammatory rheumatic diseases, delineating the future lines of development for a rational use of epigenetic information in clinical settings and in personalized medicine. These advances include the identification of epipolymorphisms associated with clinical outcomes, DNA methylation as a contributor to disease susceptibility in rheumatic conditions, the discovery of novel epigenetic mechanisms that modulate disease susceptibility and the development of new epigenetic therapies.

    2008-11-01

    Full Text Available Abstract Background Trans-mitral Doppler produces complex patterns with a great deal of variability. There are several confusing numerical measures and indices to study these patterns. However trans-mitral Doppler produces readymade data visualization by pattern generation which could be interpreted by pattern analysis. By following a systematic approach we could create an order and use this tool to study cardiac function. Presentation of the hypothesis In this new approach we eliminate the variables and apply pattern recognition as the main criterion of study. Proper terminologies are also devised to avoid confusion. In this way we can get some meaningful information. Testing the hypothesis Trans-mitral Doppler should be seen as patterns rather than the amplitude. The hypothesis can be proven by logical deduction, extrapolation and elimination of variables. Trans-mitral flow is also analyzed vis-à-vis the Starling's Law applied to the left atrium. Implications of the hypothesis Trans-mitral Doppler patterns are not just useful for evaluating diastolic function. They are also useful to evaluate systolic function. By following this schema we could get useful diagnostic information and therapeutic options using simple pattern recognition with minimal measurements. This simplified but practical approach will be useful in day to day clinical practice and help in understanding cardiac function better. This will also standardize research and improve communication.

    1993-01-01

    Valvular regurgitation can be detected as a region of signal loss ('flow void') by cardiac cine magnetic resonance (MR) imaging. Cine MR images of 36 patients with mitral regurgitation caused by mitral valve prolapse (MVP) and non-MVP were evaluated and compared with color Doppler flow images. The direction, distance, area and timing of flow void were detected in all patients in several different planes at mitral level with a 0.5 Tesla superconducting magnet by an ECG-gated fast field echo technique. In 23 of the 36 patients contiguous multiple transaxial images were also obtained to calculate the volumes of flow void and the left atrium. The direction of flow void tended to deviate to the opposite side within the left atrium in MVP. The frame showing maximal area of flow void was demonstrated in mid-systole in 24 of the 36 patients (67%). The distance, area and volume of flow void were concordant with the grade from color Doppler flow images. The volumes of flow void and the left atrium correlated (n=19, r=0.74, p<0.05) in MVP. In conclusion, cine MR images in several different planes or contiguous multiple slices are useful in determining spatial orientation and the extent and timing of mitral regurgitation noninvasively. Furthermore, calculation of the volume of flow void enables the assessment of the semiquantitation of mitral regurgitation. (author)

  18. Mitral valve repair: an echocardiographic review: Part 2.

    2015-04-01

    Echocardiographic imaging of the mitral valve before and immediately after repair is crucial to the immediate and long-term outcome. Prior to mitral valve repair, echocardiographic imaging helps determine the feasibility and method of repair. After the repair, echocardiographic imaging displays the new baseline anatomy, assesses function, and determines whether or not further management is necessary. Three-dimensional imaging has improved the assessment of the mitral valve and facilitates communication with the surgeon by providing the surgeon with an image that he/she might see upon opening up the atrium. Further advancements in imaging will continue to improve the understanding of the function and dysfunction of the mitral valve both before and after repair. This information will improve treatment options, timing of invasive therapies, and advancements of repair techniques to yield better short- and long-term patient outcomes. The purpose of this review was to connect the echocardiographic evaluation with the surgical procedure. Bridging the pre- and post-CPB imaging with the surgical procedure allows a greater understanding of mitral valve repair.

    We describe a successful percutaneous transluminal dilatation (PTD) of an innominate artery stenosis in a 40-year-old patient with aortic arch syndrome. Five years earlier both a left central carotid artery occlusion and an innominate and left subclavian artery stenosis were treated by grafting from the aorta to the distal vessels. At recurrence of the neurological symptoms, reocclusion of the graft to the innominate artery and subtotal stenosis of the left carotid anastomosis were noted. The prevent the hazards of a reoperation, the innominate artery stenosis was dilated by means of PTD via the right brachial artery. Success of the procedure was demonstrated by Doppler sonography and angiography. It appears that PTD serves as an excellent method of treating stenoses of the aortic arch branches in aortic arch syndrome. (orig.)

    To describe the frequency of rheuma­tic diseases in Portugal through a systematic review of published literature, critically appraising available information and identifying data collection gaps. We systematically reviewed the literature to retrieve data on the occurrence of rheumatic diseases in Portugal through MEDLINE and Índex das Revistas Médicas Portuguesas searches, PhD theses, and national health surveys reports. Original articles in English or Portuguese published between 1 January 2000 and 31 December 2010 were included. We retrieved information for the prevalence of rheumatic diseases, osteoarthritis, back pain, work-related musculoskeletal disorders (WRMDs), osteoporosis, fibromyalgia, rheumatoid arthritis, spondyloarthritis and other systemic rheumatic diseases and for the incidence of back pain, osteoporotic fracture and other systemic rheumatic diseases. The prevalence of rheumatic diseases ranged from 16.0% to 24.0% and the prevalence of osteoarthritis was 11.1% (95% confidence intervals (95%CI): 9.4-13.1) in the knee and 5.5% (95%CI: 4.3-7.0) in the hip. Regarding back pain, period prevalence ranged from 8.0% (95%CI: 6.1-10.1) to 29.5% (95%CI: 23.4-36.2) in children and from 12.3% (95%CI: 10.5-14.3) to 51.3% (95%CI: 48.6-53.9) in adults. The prevalence of WRMDs ranged from 5.9% to 84.2% (95%CI: 80.8-87.3). The yearly incidence of osteoporotic fracture (per 100 000) ranged from 93.3 to 481 (95%CI: 407-564) in women and from 31.9 to 154 (95%CI: 106-218) in men. The prevalence of osteoporosis in women ranged from 11.0% to 15.4% (95%CI: 13.4-17.6) and in men from 1.1% to 16.8% (95%CI: 12.2-22.3). The prevalence of fibromyalgia ranged from 3.6% (95%CI: 2.0-5.2) to 3.7% (95%CI: 2.0-5.4). The prevalence estimates of ankylosing spondylitis and of spondyloarthritis were 0.6% and 1.6% (95%CI: 0.8-2.7), respectively. The prevalence of systemic lupus erythematosus was estimated in 0.2% (95%CI: 0.1-0.8). There is a broad spectrum of information available

    Echocardiographic analysis of mitral valve (MV) has become essential for diagnosis and management of patients with MV disease. Currently, the various software used for MV analysis require manual input and are prone to interobserver variability in the measurements. The aim of this study is to determine the interobserver variability in an automated software that uses artificial intelligence for MV analysis. Retrospective analysis of intraoperative three-dimensional transesophageal echocardiography data acquired from four patients with normal MV undergoing coronary artery bypass graft surgery in a tertiary hospital. Echocardiographic data were analyzed using the eSie Valve Software (Siemens Healthcare, Mountain View, CA, USA). Three examiners analyzed three end-systolic (ES) frames from each of the four patients. A total of 36 ES frames were analyzed and included in the study. A multiple mixed-effects ANOVA model was constructed to determine if the examiner, the patient, and the loop had a significant effect on the average value of each parameter. A Bonferroni correction was used to correct for multiple comparisons, and P = 0.0083 was considered to be significant. Examiners did not have an effect on any of the six parameters tested. Patient and loop had an effect on the average parameter value for each of the six parameters as expected (P < 0.0083 for both). We were able to conclude that using automated analysis, it is possible to obtain results with good reproducibility, which only requires minimal user intervention.

    Full Text Available Background- Mitral valve prolapse syndrome (MVP is most common valvular abnormality in young and is correlated with increased frequency of cardiac dysrhythmias and sudden death. The aim of this study was to compare frequency of "early repolarization" in electrocardiogram (ECG between MVP patients and healthy adults. Methods- In this cross-sectional study, we compared ECG presentations of early repolarization including notch in descending arm of QRS and J-point and/or ST segment changes in 100 patients with MVP with 100 healthy individuals. MVP patients were referred to cardiology clinic with symptoms of palpitation, chest pain or anxiety. Results-The mean age in patients with MVP was significantly less than healthy subjects (29.5 ± 9.3 years versus 31.0 ± 6.9 years in control group, p=0.1967. We detected an early repolarization as a prevalent sign in ECG of patients, which was a notch in descending arm of QRS and/or ST segment or J-point elevation seen in 74% of patients ( 51% in inferior leads and 23% in I and aVL leads , whilst the same findings was seen in 8 men (8% in control group (p=0.0001. Conclusion- Early repolarization in ECG presented as a notch in descending arm of QRS and/or ST segment or J-point elevation is more frequent in in young patients with MVP syndrome.

    In the present study, 3 different methods to measure the mitral valve area (MVA) after mitral valve repair (MVRep) were studied. Data obtained immediately after repair were compared with postoperative data. The objective was to determine the feasibility and correlation between intraoperative and postoperative MVA data. A prospective study. A tertiary care medical center. Twenty-five elective adult surgical patients scheduled for MVRep. Echocardiographic data included MVAs obtained using the pressure half-time (PHT), 2-dimensional planimetry (2D-PLAN), and the continuity equation (CE). These data were obtained immediately after cardiopulmonary bypass and were compared with data obtained before hospital discharge (transthoracic echocardiogram 1) and 6 to 12 months after surgery (transthoracic echocardiogram 2). Intraoperative care was guided by hemodynamic goals designed to optimize cardiac function. The data show good agreement and correlation between MVA obtained with PHT and 2D-PLAN within and between each time period. MVA data obtained with the CE in the postoperative period were lower than and did not correlate or agree as well with other MVA data. The MVA recorded immediately after valve repair, using PHT, correlated and agreed with MVA data obtained in the postoperative period. These results contrast with previously published data and could highlight the impact of hemodynamic function during the assessment of MVA. Copyright © 2011 Elsevier Inc. All rights reserved.

    International records indicate that only 2.6% of patients with heart transplants have valvular heart disease. The study aim was to evaluate the epidemiological and clinical profile of patients with valvular heart disease undergoing heart transplantation. Between 1985 and 2013, a total of 569 heart transplants was performed at the authors' institution. Twenty patients (13 men, seven women; mean age 39.5 +/- 15.2 years) underwent heart transplant due to structural (primary) valvular disease. Analyses were made of the patients' clinical profile, laboratory data, echocardiographic and histopathological data, and mortality and rejection. Of the patients, 18 (90%) had a rheumatic etiology, with 85% having undergone previous valve surgery (45% had one or more operations), and 95% with a normal functioning valve prosthesis at the time of transplantation. Atrial fibrillation was present in seven patients (35%), while nine (45%) were in NYHA functional class IV and eight (40%) in class III. The indication for cardiac transplantation was refractory heart failure in seven patients (35%) and persistent NYHA class III/IV in ten (50%). The mean left ventricular ejection fraction (LVEF) was 26.6 +/- 7.9%. The one-year mortality was 20%. Histological examination of the recipients' hearts showed five (27.7%) to have reactivated rheumatic myocarditis without prior diagnosis at the time of transplantation. Univariate analysis showed that age, gender, LVEF, rheumatic activity and rejection were not associated with mortality at one year. Among the present patient cohort, rheumatic heart disease was the leading cause of heart transplantation, and a significant proportion of these patients had reactivated myocarditis diagnosed in the histological analyses. Thus, it appears valid to investigate the existence of rheumatic activity, especially in valvular cardiomyopathy with severe systolic dysfunction before transplantation.

    Subglottic stenosis is an abnormal narrowing of the tracheal lumen at the level of subglottis (the area in between the vocal cords and the cricoid cartilage). It can cause significant symptoms due to severe attenuation of airflow. We describe our experience in alleviating symptoms by addressing the stenosis using fibreoptic bronchoscopic methods. We report all concurrent cases performed between September 2015 and July 2016. We use a combination of balloon dilation, electro-surgery knife to dilate and incise stenotic segments followed by steroid injection to modulate healing. We treated 10 patients in the study period, 8 of which were women. A total of 39 procedures were performed on these patients during this period. Gastro-esophageal reflux was the most common comorbidity associated with stenosis. The majority of the patients required more than 2 therapeutic procedures, but none required more than 4 procedures. There were no complications. Tracheal stenosis and in particular subglottic stenosis is a recurrent process and its management requires extensive collaboration amongst treating specialties. Our technique of steroid injection after dilation of the stenosis was effective in symptom control and decreased the number of repeat procedures.

To describe the embryological development of the IAC structures and the natural history of IAC stenosis. Methods: A 4 year old girl presents with sensorineural hearing loss and bilateral recurrent otitis media. The temporal bone CT shows diminished left IAC diameter (less than 2 mm), right IAC absence and normal inner ear structures. These findings are pathognomonic for left IAC stenosis. The MR findings include left IAC stenosis and IAC neural structures absence secondary to aplasia of the vestibulocochlear nerve on each IAC . Results: Hypoplasia/aplasia of the vestibulocochlear nerve in association with IAC stenosis is an important consideration in the differential diagnosis of sensorineural hearing loss, as it is a relative contraindication for cochlear implant placement. Conclusions: IAC stenosis and vestibulocochlear nerve hypoplasia/aplasia must be excluded as an etiology of sensorineural hearing loss. The diagnosis can be made by CT and MR.

    Intracranial stenosis is a common vascular lesion observed in Asian and other non-Caucasian stroke populations. However, its role in cognitive impairment and dementia has been under-studied. We, therefore, examined the association of intracranial stenosis with cognitive impairment, dementia and their subtypes in a memory clinic case-control study, where all subjects underwent detailed neuropsychological assessment and 3 T neuroimaging including three-dimensional time-of-flight magnetic resonance angiography. Intracranial stenosis was defined as ≥50% narrowing in any of the intracranial arteries. A total of 424 subjects were recruited of whom 97 were classified as no cognitive impairment, 107 as cognitive impairment no dementia, 70 vascular cognitive impairment no dementia, 121 Alzheimer's Disease, and 30 vascular dementia. Intracranial stenosis was associated with dementia (age/gender/education - adjusted odds ratios (OR): 4.73, 95% confidence interval (CI): 1.93-11.60) and vascular cognitive impairment no dementia (OR: 3.98, 95% CI: 1.59-9.93). These associations were independent of cardiovascular risk factors and MRI markers. However, the association with Alzheimer's Disease and vascular dementia became attenuated in the presence of white matter hyperintensities. Intracranial stenosis is associated with vascular cognitive impairment no dementia independent of MRI markers. In Alzheimer's Disease and vascular dementia, this association is mediated by cerebrovascular disease. Future studies focusing on perfusion and functional markers are needed to determine the pathophysiological mechanism(s) linking intracranial stenosis and cognition so as to identify treatment strategies.

    The surgical management of mitral valve disease in women of childbearing age, young patients, and children with congenital mitral valve defects is made difficult by the prospect of lifelong anticoagulation. We suggest the use of a pulmonary autograft in the mitral position (Ross II procedure) as an alternative surgical technique. We present a review of the literature, historical perspectives, indications, selection criteria, and surgical technique for the Ross II procedure. Our literature search identified 14 studies that reported results from the Ross II operation. Performed in 103 patients, the overall in-hospital mortality was 7 (6.7%), with a late mortality of 10 (9%). Although further research is needed, current evidence suggests the Ross II operation is a valuable alternative in low-risk young patients where valve durability and the complication rate from other procedures is unsatisfactory and anticoagulation not ideal.

    Surgical isolation of the left atrium was performed for the treatment of chronic atrial fibrillation secondary to valvular disease in 100 patients who underwent mitral valve operations. From May 1989 to September 1991, 62 patients underwent mitral valve operations (group I); 19, mitral valve operations and DeVega tricuspid annuloplasty (group II); 15, mitral and aortic operations (group III); and 4, mitral and aortic operations and DeVega tricuspid annuloplasty (group IV). Left atrial isolation was performed, prolonging the usual left paraseptal atriotomy toward the left fibrous trigone anteriorly and the posteromedial commissure posteriorly. The incision was conducted a few millimeters apart from the mitral valve annulus, and cryolesions were placed at the edges to ensure complete electrophysiological isolation of the left atrium. Operative mortality accounted for 3 patients (3%). In 79 patients (81.4%) sinus rhythm recovered and persisted until discharge from the hospital. No differences were found between the groups (group I, 80.7%; group II, 68.5%; group III, 86.7%; group IV, 75%; p = not significant). Three late deaths (3.1%) were registered. Long-term results show persistence of sinus rhythm in 71% of group I, 61.2% of group II, 85.8% of group III, and 100% of group IV. The unique risk factor for late recurrence of atrial fibrillation was found to be preoperative atrial fibrillation longer than 6 months. Due to the satisfactory success rate in recovering sinus rhythm, we suggest performing left atrial isolation in patients with chronic atrial fibrillation undergoing valvular operations.

    In this review, we discuss the current evidence supporting each minimally invasive mitral repair approach and their associated controversies. Current evidence demonstrates that minimally invasive mitral repair techniques yield similar mitral repair results to conventional sternotomy with the benefits of shorter hospital stay, quicker recovery, better cosmesis and improved patient satisfaction. Despite this, broad adoption of minimally invasive mitral repair is still not achieved. Two main approaches of minimally invasive mitral repair exist: endoscopic mini-thoracotomy and robotic-assisted approaches. Both minimally invasive approaches share many commonalities; however, most centres are strongly polarized to one approach over another creating controversy and debate about the most effective minimally invasive approach.

    A 69-year-old female underwent cardiac CT to evaluate prosthetic valve (PHV) dysfunction detected on echocardiography. A CT coronal and en face views of the mitral annular plane showed a low-density, mass-like lesion on the left atrial side of the PHV and a high-density, plate-like lesion on the left ventricular side of PHV. A repeat of the mitral valve replacement was performed, and preoperative CT findings of both the thrombus on the left atrial side and pannus formation on the LV side were confirmed in the operative findings.

    Mitral valve morphology after mitral valve surgery affects postoperative intraventricular flow patterns and long-term cardiac performance. We visualized ventricular flow by echocardiography vector flow mapping (VFM) to reveal the impact of different mitral valve procedures. Eleven cases of mechanical mitral valve replacement (nine in the anti-anatomical and two in the anatomical position), three bioprosthetic mitral valve replacements, and four mitral valve repairs were evaluated. The mean age at the procedure was 57.4 ± 17.8 year, and the echocardiography VFM in the apical long-axis view was performed 119.9 ± 126.7 months later. Flow energy loss (EL), kinetic pressure (KP), and the flow energy efficiency ratio (EL/KP) were measured. The cases with MVR in the anatomical position and with valve repair had normal vortex directionality ("Clockwise"; N = 6), whereas those with MVR in the anti-anatomical position and with a bioprosthetic mitral valve had the vortex in the opposite direction ("Counterclockwise"; N = 12). During diastole, vortex direction had no effect on EL ("Clockwise": 0.080 ± 0.025 W/m; "Counterclockwise": 0.083 ± 0.048 W/m; P = 0.31) or KP ("Clockwise": 0.117 ± 0.021 N; "Counterclockwise": 0.099 ± 0.057 N; P = 0.023). However, during systole, the EL/KP ratio was significantly higher in the "Counterclockwise" vortex than that in the "Clockwise" vortex (1.056 ± 0.463 vs. 0.617 ± 0.158; P = 0.009). MVP and MVR with a mechanical valve in the anatomical position preserve the physiological vortex, whereas MVR with a mechanical valve in the anti-anatomical position and a bioprosthetic mitral valve generate inefficient vortex flow patterns, resulting in a potential increase in excessive cardiac workload.

    Osteogenesis imperfecta is a disorder of the connective tissue that affects several structures including heart valves. However, cardiac surgery is associated with high mortality and morbidity rates. In a 48-year-old man with osteogenesis imperfecta and mitral valve prolapse, we performed the first successful mitral valve repair by right anterior mini-thoracotomy. At the 1-year follow-up, he was asymptomatic and echocardiography confirmed the initial success. © The Author 2017.

    There has in recent years been great concern about possible cardiac side effects of thiazolidinediones (TZDs). We present a case-report of a 60 year-old male who developed significant mitral regurgitation during six months treatment with pioglitazone in parallel with laboratory indications of fluid retention. Echocardiography six months after discontinuation of medication showed regression of mitral regurgitation and the laboratory parameters were also normalized. It is noteworthy that six months treatment with pioglitazone could induce significant valve dysfunction, which was reversible, and this underlines the importance of carefully monitoring patients when placing them on treatment with TZDs.

    Full Text Available A 37-year-old male with known intravenous drug use was admitted with an acute onset of worsening confusion and speech impairment. His vitals and biochemical profile demonstrated severe sepsis, with a brain CT showing several lesions suspicious for cerebral emboli. He then went on to have a bedside transthoracic echocardiogram that was positive for vegetation on the mitral valve, with associated severe mitral regurgitation. Unfortunately, before he was stable enough to be transferred for valve surgery, he suffered an episode of acute pulmonary oedema requiring intubation and ventilation on intensive care unit.

    Full Text Available Background: Echocardiographic analysis of mitral valve (MV has become essential for diagnosis and management of patients with MV disease. Currently, the various software used for MV analysis require manual input and are prone to interobserver variability in the measurements. Aim: The aim of this study is to determine the interobserver variability in an automated software that uses artificial intelligence for MV analysis. Settings and Design: Retrospective analysis of intraoperative three-dimensional transesophageal echocardiography data acquired from four patients with normal MV undergoing coronary artery bypass graft surgery in a tertiary hospital. Materials and Methods: Echocardiographic data were analyzed using the eSie Valve Software (Siemens Healthcare, Mountain View, CA, USA. Three examiners analyzed three end-systolic (ES frames from each of the four patients. A total of 36 ES frames were analyzed and included in the study. Statistical Analysis: A multiple mixed-effects ANOVA model was constructed to determine if the examiner, the patient, and the loop had a significant effect on the average value of each parameter. A Bonferroni correction was used to correct for multiple comparisons, and P = 0.0083 was considered to be significant. Results: Examiners did not have an effect on any of the six parameters tested. Patient and loop had an effect on the average parameter value for each of the six parameters as expected (P < 0.0083 for both. Conclusion: We were able to conclude that using automated analysis, it is possible to obtain results with good reproducibility, which only requires minimal user intervention.

    PURPOSE: To compare the prevalence of mitral valve prolapse (MVP in patients with keratoconus (KCN with that of normal subjects. METHODS: This study includes 62 individuals with KCN diagnosed by clinical findings and topographic criteria, and 167 age and sex matched controls with no clinical or topographic evidence of KCN. All participants were evaluated by two-dimensional M-mode and color doppler echocardiography. Perloff's criteria were used for diagnosis of definite MVP. RESULTS: Definite MVP was diagnosed in 22.6% of subjects with KCN and 6.6% of the control group (OR= 4.2; 95% CI, 1.93-11.3; P= 0.009. MVP was more prevalent in patients with KCN based on age and sex stratification. Odds ratio for MVP increased from 2.67 before the third decade of life to 33.44 in the third decade and slightly decreased to 16.52 in the fourth decade and above. CONCLUSION: This study disclosed an increased prevalence of MVP in individuals with keratoconus suggesting the necessity of cardiovascular evaluation in these patients.

    Full Text Available Abstract Background Valve dysfunction is a common cardiovascular pathology. Despite significant clinical research, there is little formal study of how valve dysfunction affects overall circulatory dynamics. Validated models would offer the ability to better understand these dynamics and thus optimize diagnosis, as well as surgical and other interventions. Methods A cardiovascular and circulatory system (CVS model has already been validated in silico, and in several animal model studies. It accounts for valve dynamics using Heaviside functions to simulate a physiologically accurate "open on pressure, close on flow" law. However, it does not consider real-time valve opening dynamics and therefore does not fully capture valve dysfunction, particularly where the dysfunction involves partial closure. This research describes an updated version of this previous closed-loop CVS model that includes the progressive opening of the mitral valve, and is defined over the full cardiac cycle. Results Simulations of the cardiovascular system with healthy mitral valve are performed, and, the global hemodynamic behaviour is studied compared with previously validated results. The error between resulting pressure-volume (PV loops of already validated CVS model and the new CVS model that includes the progressive opening of the mitral valve is assessed and remains within typical measurement error and variability. Simulations of ischemic mitral insufficiency are also performed. Pressure-Volume loops, transmitral flow evolution and mitral valve aperture area evolution follow reported measurements in shape, amplitude and trends. Conclusions The resulting cardiovascular system model including mitral valve dynamics provides a foundation for clinical validation and the study of valvular dysfunction in vivo. The overall models and results could readily be generalised to other cardiac valves.

    To identify the most accurate quantitative coronary stenosis parameter by CTA for prediction of functional significant coronary stenosis resulting in coronary revascularization. 160 consecutive patients were prospectively examined with CTA. Proximal coronary stenosis was quantified by minimal lumen area (MLA) and minimal lumen diameter (MLD), %area and %diameter stenosis. Lesion length (LL) was measured. The reference standard was invasive coronary angiography (ICA) (>70 % stenosis, FFR <0.8). 210 coronary segments were included (59 % positive). MLA of ≤1.8 mm{sup 2} was identified as the optimal cut-off (c = 0.97, p < 0.001; 95 % CI 0.94-0.99) (sensitivity 90.9 %, specificity 89.3 %) for prediction of functional-relevant stenosis (for MLA >2.1 mm{sup 2} sensitivity was 100 %). The optimal cut-off for MLD was 1.2 mm (c = 0.92; p < 0.001; 95 % CI 0.88-95) (sensitivity 90.9, specificity 85.2) while %area and %diameter stenosis were less accurate (c = 0.89; 95 % CI 0.84-93, c = 0.87; 95 % CI 0.82-92, respectively, with thresholds at 73 % and 61 % stenosis). Accuracy for LL was c = 0.74 (95 % CI 0.67-81), and for LL/MLA and LL/MLD ratio c = 0.90 and c = 0.84. MLA ≤1.8 mm{sup 2} and MLD ≤1.2 mm are the most accurate cut-offs for prediction of haemodynamically significant stenosis by ICA, with a higher accuracy than relative % stenosis. (orig.)

    We performed 45 cases of Natural folding plasty without leaflet resection for degenerative mitral regurgitation (MR) between September 2005 and July 2014. Twenty cases of 45 were operated by right small intercostal approach (MICS). There was no operative mortality. No patient had greater than mild MR intraoperative transesophageal echocardiography. The median follow-up was 847 (19~1,747) days. One case needed a second pump run performed without complication. One patient had a reoperation performed for recurrent MR 20 months later. Natural folding plasty for degenerative MR with favorable long term out come in our results. This technique is simple and reproducible for most surgeons. Furthermore, with its simplicity and reversibility, we considered it to be suitable for MICS approach.

  8. The accuracy of echocardiography versus surgical and pathological classification of patients with ruptured mitral chordae tendineae: a large study in a Chinese cardiovascular center

    2011-01-01

    Background The accuracy of echocardiography versus surgical and pathological classification of patients with ruptured mitral chordae tendineae (RMCT) has not yet been investigated with a large study. Methods Clinical, hemodynamic, surgical, and pathological findings were reviewed for 242 patients with a preoperative diagnosis of RMCT that required mitral valvular surgery. Subjects were consecutive in-patients at Fuwai Hospital in 2002-2008. Patients were evaluated by thoracic echocardiography (TTE) and transesophageal echocardiography (TEE). RMCT cases were classified by location as anterior or posterior, and classified by degree as partial or complete RMCT, according to surgical findings. RMCT cases were also classified by pathology into four groups: myxomatous degeneration, chronic rheumatic valvulitis (CRV), infective endocarditis and others. Results Echocardiography showed that most patients had a flail mitral valve, moderate to severe mitral regurgitation, a dilated heart chamber, mild to moderate pulmonary artery hypertension and good heart function. The diagnostic accuracy for RMCT was 96.7% for TTE and 100% for TEE compared with surgical findings. Preliminary experiments demonstrated that the sensitivity and specificity of diagnosing anterior, posterior and partial RMCT were high, but the sensitivity of diagnosing complete RMCT was low. Surgical procedures for RMCT depended on the location of ruptured chordae tendineae, with no relationship between surgical procedure and complete or partial RMCT. The echocardiographic characteristics of RMCT included valvular thickening, extended subvalvular chordae, echo enhancement, abnormal echo or vegetation, combined with aortic valve damage in the four groups classified by pathology. The incidence of extended subvalvular chordae in the myxomatous group was higher than that in the other groups, and valve thickening in combination with AV damage in the CRV group was higher than that in the other groups.

    We recently reported the feasibility of the average pixel intensity (API) method for grading mitral regurgitation (MR) in a heterogeneous MR population. Since mitral valve prolapse (MVP) is an important cause of primary MR, we more specifically investigated the feasibility of the API method and the MR flow dynamics in patients with MVP. Transthoracic echocardiography was performed by a single operator in consecutive MVP patients (n=112). MR was assessed using the API method, color Doppler, vena contracta width (VCW), effective regurgitant orifice area (PISA-EROA) and regurgitant volume (PISA-RV). The API method was feasible in 89% of all MVP patients (68%, 71% for VCW and PISA method, respectively ;pMVP with non-holosystolic MR were 0.989 and 0.995. For the overall MVP-MR population, API had significant correlations with direct and indirect measures of MR severity. Based on ROC curves, an API cutoff value of 125 au was suggested to identify severe MR in MVP and a MR duration/systolic time ratioMVP-MR) identifies patients with non-severe MR (APIMVP had severe MR (API>125). Finally, API analysis of the proto-, mid- and telesystolic phases of MR in MVP showed different kinetics in non-holosystolic compared to holosystolic MVP. The API method is a feasible and reproducible method for grading MVP-MR. As the API method takes into account the temporal MR flow changes during the entire systolic cycle, it may be of added value in clinical practice. Copyright © 2018 Elsevier B.V. All rights reserved.

  10. Percutaneous Mitral Valve Repair in Mitral Regurgitation Reduces Cell-Free Hemoglobin and Improves Endothelial Function.

    Christos Rammos

    Full Text Available Endothelial dysfunction is predictive for cardiovascular events and may be caused by decreased bioavailability of nitric oxide (NO. NO is scavenged by cell-free hemoglobin with reduction of bioavailable NO up to 70% subsequently deteriorating vascular function. While patients with mitral regurgitation (MR suffer from an impaired prognosis, mechanisms relating to coexistent vascular dysfunctions have not been described yet. Therapy of MR using a percutaneous mitral valve repair (PMVR approach has been shown to lead to significant clinical benefits. We here sought to investigate the role of endothelial function in MR and the potential impact of PMVR.Twenty-seven patients with moderate-to-severe MR treated with the MitraClip® device were enrolled in an open-label single-center observational study. Patients underwent clinical assessment, conventional echocardiography, and determination of endothelial function by measuring flow-mediated dilation (FMD of the brachial artery using high-resolution ultrasound at baseline and at 3-month follow-up. Patients with MR demonstrated decompartmentalized hemoglobin and reduced endothelial function (cell-free plasma hemoglobin in heme 28.9±3.8 μM, FMD 3.9±0.9%. Three months post-procedure, PMVR improved ejection fraction (from 41±3% to 46±3%, p = 0.03 and NYHA functional class (from 3.0±0.1 to 1.9±1.7, p<0.001. PMVR was associated with a decrease in cell free plasma hemoglobin (22.3±2.4 μM, p = 0.02 and improved endothelial functions (FMD 4.8±1.0%, p<0.0001.We demonstrate here that plasma from patients with MR contains significant amounts of cell-free hemoglobin, which is accompanied by endothelial dysfunction. PMVR therapy is associated with an improved hemoglobin decompartmentalization and vascular function.

    Full Text Available Degenerative mitral valvular disease (DMVD is the most frequent cardiac disease, causing mitral regurgitation (MR in dogs. The purpose of this study was to compare the ratio of the regurgitant jet area (RJA to the left atrial area (LAA (RJA/LAA with subtracting method to quantify regurgitant volume (RegV and regurgitant fraction (RF in asymptomatic Anatolian Shepherd Dogs (ASHs with DMVD. Thirty-eight ASHs with DMVD were used as experimental group. The control group consisted of 35 healthy ASHs. In 38 ASHs with DMVD (20 B1 dogs and 18 B2 dogs, the severity of MR was assessed by RJA/LAA and subtraction method. No differences were noted between the assays measuring the severity of MR by χ2 analysis. The observed agreement between the assays was 81% for RJA/LAA vs RegV and was 73% for RJA/LAA vs RF, and the kappa statistic values for RJA/LAA vs RegV and for RJA/LAA vs RF were 0.63 (substantial agreement and 0.50 (moderate agreement, respectively. Our results indicate that each quantification method was valuable to estimate the acuteness of the disease in ASHs with MR and all were in good accordance with the echocardiographic heart size and N-terminal Pro-Brain Natriuretic Peptide (NT-proBNP measurements. Therefore, the each of these non-invasive methods may be functional to serially estimate the acuteness of MR in DMVD in order to monitor the progression of disease. Future studies have to evaluate, if these will be useful to anticipate the risk or time of decompensation in asymptomatic dogs.

    Many patients undergoing transcatheter aortic valve implantation (TAVI) have concomitant mitral regurgitation (MR) of moderate grade or less. The impact of coexistent tricuspid regurgitation (TR) remains to be determined. We sought to analyze the impact of moderate vs none-to-mild MR and its trend after TAVI, as well as the impact of concomitant TR and its interaction with MR. Multicenter retrospective study of 813 TAVI patients treated through the transfemoral approach with MR ≤ 2 between 2007 and 2015. The mean age was 81 ± 7 years and the mean Society of Thoracic Surgeons score was 6.9% ± 5.1%. Moderate MR was present in 37.3% of the patients, with similar in-hospital outcomes and 6-month follow-up mortality to those with MR 2 post-TAVI. The presence of concomitant moderate/severe TR was associated with in-hospital and follow-up mortality rates of 13% and 34.1%, respectively, regardless of MR grade. Moderate-severe TR was independently associated with mortality (HR, 18.4; 95%CI, 10.2-33.3; P < .001). The presence of moderate MR seemed not to impact short- and mid-term mortality post-TAVI, but was associated with more rehospitalizations. The presence of moderate or severe TR was associated with higher mortality. This suggests that a thorough evaluation of the mechanisms underlying concomitant mitral and tricuspid valve regurgitation should be performed to determine the best strategy for avoiding TAVI-related futility.

    This study aimed to investigate the luminal stenosis of the internal carotid artery with calcification detected on panoramic radiographs. This study used fifty carotid arteries of 36 dental patients whose panoramic radiograph and computed tomography angiography (CTA) revealed the presence of carotid artery calcification. A neuroradiologist interpreted CTA to determine the degree of stenosis of the internal carotid arteries. The degree of stenosis was stratified in four stages; normal (no stenosis), mild stenosis (1-49%), moderate stenosis (50-69%) and severe stenosis (70-99%). Among the fifty carotid arteries with calcification detected on both panoramic radiography and CTA, 20 carotid arteries (40%) were normal, 29 carotid arteries (18%) had mild stenosis, 1 carotid artery (2%) had moderate stenosis, and there was none with severe stenosis. Sixty percent of the carotid arteries with calcification detected on both panoramic radiography and CTA had internal luminal stenosis, and two percent had moderate stenosis. When carotid atheroma is detected on panoramic radiograph, it is possible that the dental patient has luminal stenosis of the internal carotid artery.

    Rheumatic diseases refer to many diseases with a loss of immune self-tolerance, leading to a chronic inflammation, degeneration, or metabolic derangement in multiple organs or tissues. The cause of rheumatic diseases remains to be elucidated, though both environmental and genetic factors are required for the development of rheumatic diseases. Over the past decades, emerging studies suggested that alteration of intestinal microbiota, known as gut dysbiosis, contributed to the occurrence or development of a range of rheumatic diseases, including rheumatoid arthritis, systemic lupus erythematosus, ankylosing spondylitis, systemic sclerosis, and Sjogren's syndrome, through profoundly affecting the balance between pro- and anti-inflammatory immune responses. In this article, we discussed the role of gut microbiota in the pathogenesis of rheumatic diseases based on a large number of experimental and clinical materials, thereby providing a new insight for microbiota-targeted therapies to prevent or cure rheumatic diseases.

    Patients with rheumatic diseases have an increased risk of mortality by cardiovascular events. In fact, several rheumatic diseases such as rheumatoid arthritis, osteoarthritis, systemic lupus erythematosus, and ankylosing spondylitis are associated with a higher prevalence of cardiovascular diseases (CVDs). Although traditional cardiovascular risk factors have been involved in the pathogenesis of cardiovascular diseases in rheumatic patients, these alterations do not completely explain the enhanced cardiovascular risk in this population. Obesity and its pathologic alteration of fat mass and dysfunction, due to an altered pattern of secretion of proinflammatory adipokines, could be one of the links between cardiovascular and rheumatic diseases. Indeed, the incidence of CVDs is augmented in obese individuals with rheumatic disorders. Thus, in this paper we explore in detail the relationships among adipokines, rheumatic diseases, and cardiovascular complications by giving to the reader a holistic vision and several suggestions for future perspectives and potential clinical implications.

    Rare rheumatic diseases present unique challenges to knowledge translation (KT) researchers. There is often an urgent need to transfer knowledge from research findings into clinical practice to facilitate earlier diagnosis and better outcomes. However, existing KT frameworks have not addressed the specific considerations surrounding rare diseases for which gold standard evidence is not available. Several widely adopted models provide guidance for processes and problems associated with KT. However, they do not address issues surrounding creation or synthesis of knowledge for rare diseases. Additional problems relate to lack of awareness or experience in intended knowledge users, low motivation, and potential barriers to changing practice or policy. Strategies to address the challenges of KT for rare rheumatic diseases include considering different levels of evidence available, linking knowledge creation and transfer directly, incorporating patient and physician advocacy efforts to generate awareness of conditions, and selecting strategies to address barriers to practice or policy change.

    The rheological properties of synovial fluids from patients with different rheumatic diseases are discussed. Viscosities of 73 samples were determined and are compared to a standard of "healthy" human synovial fluid p. m. and to bovine synovia. Typical differences between "healthy", degenerative and inflammatory synovial fluids could be discerned. These differences can be characterized with several rheological parameters. The mechanism of lubrication in joints and the role of synovial fluid as a lubricant are discussed. Rheological properties of polymere solutions which could serve as a substitute for sick synovial fluids are described and compared to the properties of healthy synovia. Several possibilities for molecular changes which could account for the deterioration of synovial fluids in patients with different rheumatic diseases are discussed.

    Evaluating the risk of falling of a geriatric rheumatic patient plays an essential role not only in planning and carrying out the physiotherapeutic process. The consequences of falls may be different and, although they do not always result in serious repercussions such as fractures or injuries, it is sufficient that they generate the fear of falling and cause a significant reduction in physical activity. Assessing functional capacity to define the risk of falling is of utmost importance in the case of patients after joint arthroplasty surgeries. The specificity of rheumatic patient's falls is determined by numerous factors. It is not always possible to avoid them. However, it becomes vital to include fall prevention in the rehabilitation process as well as to prepare the house for the needs of an elderly person so that they are safe and as self-dependent as possible.

    Treatment of rheumatic diseases with X-rays today still has some certain indications such as activated arthrosis, inflammatory insertion tendopathies, so-called periarthritis, ankylosing spondilytis, and - with reserve - cervical and lumbar syndromes. For X-radiation of rheumatic diseases, the rules and methods of the so-called inflammation radiation in low dosages are valid. Despite contradictory statements in the relevant literature, it is not proved that irradiation of the spinal column of patients with ankylosing spondylitis involves the danger of radiogenic leukaemia. Certain irradiations of joints, however, (e.g. hip joint, sacro-iliac joints) lead to a gonadal exposure (esp. in the case of women of reproductive age) which cannot be tolerated by any physician.

    The aim of this study was to evaluate typical magnetic resonance imaging (MRI) findings in early rheumatic diseases manifesting at the soft tissues of the hand using a retrospective analysis. A total of 186 MRI examinations of patients with clinical suspicion of a rheumatic disease were evaluated in a consensus reading by two experienced radiologists. All imaging patterns were assessed with respect to their type and localization. Under blinded and non-blinded conditions diagnoses were correlated with final clinical diagnosis. The most frequent diagnoses were rheumatoid arthritis (RA, 45.7%) and psoriatic arthritis (PsA, 15.6%). The mean correlation between clinical and MRI diagnosis (r) was 0.75 in blinded and 0.853 in non-blinded reading (p [de
