There are few quantitative data on the extent or mechanism of pulmonary artery catheter (PAC)-induced valvular dysfunction. We hypothesized that PACs cause or worsen tricuspid and pulmonic valvular regurgitation, and tested this hypothesis by using transesophageal echocardiography. In 54 anesthetized adult patients, we measured color Doppler jet areas of tricuspid regurgitation (TR) in two planes (midesophageal [ME] 4-chamber and right ventricular inflow-outflow views) and pulmonic insufficiency (PI) in one plane (ME aortic valve long-axis view), both before and after we advanced a PAC into the pulmonary artery. Regurgitant jet areas and hemodynamic measurements were compared by using paired t-test. There were no significant changes in blood pressure or heart rate after passage of the PAC. After PAC placement, the mean PI jet area was not significantly increased. The mean TR jet area increased significantly in the right ventricular inflow-outflow view (+0.37 +/- 0.11 cm(2)) (P = 0.0014), but did not increase at the ME 4-chamber view. Seventeen percent of patients had an increase in TR jet area > or =1 cm(2); 8% of patients had an increase in PI jet area >/=1 cm(2). In patients without pulmonic or tricuspid valvular pathology, placement of a pulmonary artery catheter (PAC) worsened tricuspid regurgitation, which is consistently visualized in the right ventricular inflow-outflow view, and often not seen in the midesophageal 4-chamber view. This is consistent with malcoaptation of the anterior and posterior leaflets. PAC-induced pulmonic insufficiency was rarely detected in the midesophageal aortic valve long-axis view. We conclude that a PAC is very unlikely to be the sole cause of severe tricuspid regurgitation or pulmonic insufficiency.

Apoptosis occurs in atrial cardiomyocytes in mitral and tricuspid valve disease. The purpose of this study was to examine the respective roles of the mitochondrial and tumor necrosis factor-α receptor associated death domain (TRADD)-mediated death receptor pathways for apoptosis in the atrial cardiomyocytes of heart failure patients due to severe mitral and moderate-to-severe tricuspid regurgitation. This study comprised eighteen patients (7 patients with persistent atrial fibrillation and 11 in sinus rhythm). Atrial appendage tissues were obtained during surgery. Three purchased normal human left atrial tissues served as normal controls. Moderately-to-severely myolytic cardiomyocytes comprised 59.7±22.1% of the cardiomyocytes in the right atria and 52.4±12.9% of the cardiomyocytes in the left atria of mitral and tricuspid regurgitation patients with atrial fibrillation group and comprised 58.4±24.8% of the cardiomyocytes in the right atria of mitral and tricuspid regurgitation patients with sinus rhythm. In contrast, no myolysis was observed in the normal human adult left atrial tissue samples. Immunohistochemical analysis showed expression of cleaved caspase-9, an effector of the mitochondrial pathways, in the majority of right atrial cardiomyocytes (87.3±10.0%) of mitral and tricuspid regurgitation patients with sinus rhythm, and right atrial cardiomyocytes (90.6±31.4%) and left atrial cardiomyocytes (70.7±22.0%) of mitral and tricuspid regurgitation patients with atrial fibrillation. In contrast, only 5.7% of cardiomyocytes of the normal left atrial tissues showed strongly positive expression of cleaved caspase-9. Of note, none of the atrial cardiomyocytes in right atrial tissue in sinus rhythm and in the fibrillating right and left atria of mitral and tricuspid regurgitation patients, and in the normal human adult left atrial tissue samples showed cleaved caspase-8 expression, which is a downstream effector of TRADD of the death receptor pathway

We report the unique case of a primary cardiac leiomyoma originating from the right ventricle and involving the tricuspid valve in a 43-year-old woman. Echocardiography showed a giant mass causing severe pulmonary stenosis and tricuspid valve regurgitation. The patient underwent surgical excision and histologic examination revealed a primary cardiac leiomyoma. To the best of our knowledge only three cases of primary cardiac leiomyoma have so far been reported, and this is the first case of primary cardiac leiomyoma involving the tricuspid valve apparatus.

Functional Tricuspid Regurgitation and Ring Annuloplasty Repair

Directory of Open Access Journals (Sweden)

William B. Weir, MD

2018-01-01

Full Text Available Functional tricuspid regurgitation (TR primarily arises from asymmetric dilation of the tricuspid annulus in the setting of right ventricular dysfunction and enlargement in response to left-sided myocardial and valvular abnormalities. Even if the TR is not severe at the time of mitral valve surgery, it can worsen and even appear late after successful mitral valve surgery, which portends a poor prognosis. Despite data demonstrating inferior outcomes in the presence of residual TR, surgical repair for functional TR remains underused. Acceptance of TR, in the presence of tricuspid annular dilation, may be unacceptable. Surgical repair should consist of placement of a rigid or semirigid annular ring, which has been shown to provide superior durability as compared with suture and flexible band techniques. Finally, percutaneous annuloplasty for correction of functional TR may allow treatment of patients with recurrent TR at high risk of reoperation.

Traumatic tricuspid regurgitation and right-to-left intra-atrial shunt--an unusual complication of a horse-kick.

LENUS (Irish Health Repository)

Byrne, R A

2010-02-01

A 63-year-old male presented with sudden onset chest pain and dyspnoea following a kick to the praecordium while gelding a horse. Transthoracic echocardiography showed evidence of flail tricuspid valve leaflets, severe tricuspid regurgitation and a widely patent foramen ovale with a right-to-left shunt. Due to progressive severe systemic hypoxemia the patient underwent emergent surgical intervention. Operative findings confirmed rupture of the anterior and septal tricuspid valve papillary muscles. Successful papillary muscle reattachment was performed in association with tricuspid annuloplasty and suture closure of his patent foramen ovale. Disruption of the tricuspid valve is well described as consequence of blunt trauma to the chest wall and is often well tolerated, coming to light many years post injury. Valve disruption due to rupture at the papillary muscle level, however, typically results in greater severity of tricuspid regurgitation and the abrupt rise in right intra-atrial pressure may lead to a right-to-left shunt across a patent foramen ovale. Where hemodynamic compromise ensues, prompt surgical intervention is mandated.

Severe tricuspid regurgitation (TR) is common in patients with right-sided heart failure (HF) and causes substantial morbidity and mortality. Treatment options beyond medical therapy are limited for high-risk patients. Transcatheter edge-to-edge tricuspid valve (TV) repair showed procedural safety and short-term efficacy. Impact on mid-term outcome is unclear. This dual-centre observational study evaluates the mid-term safety, efficacy and clinical outcome after edge-to-edge TV repair for severe TR in patients with HF. Overall, 50 patients with right-sided HF and severe TR were treated with the transcatheter edge-to-edge repair technique; 14 patients were treated for isolated TR and 36 patients for combined mitral regurgitation (MR) and TR. At 6-month follow-up (available for 98% of patients), a persistent reduction of at least one echocardiographic TR grade was achieved in 90% of patients and New York Heart Association class improved in 79% of patients. The 6-minute walk distance increased by 44% (+84 m, P edge-to-edge TV repair for severe TR is safe and effective in reducing TR. It appears to be associated with improved clinical outcome in the majority of patients. © 2018 The Authors. European Journal of Heart Failure © 2018 European Society of Cardiology.

To describe a novel technique, named "clover," to correct complex post-traumatic tricuspid valve lesions. Five patients with severe post-traumatic tricuspid insufficiency underwent valve reconstruction with the clover technique, a new surgical approach that consists of stitching together the middle point of the free edges of the tricuspid leaflets, producing a clover-shaped valve. The mechanism of tricuspid regurgitation was complex in all patients, and right ventricular function was always moderately to severely depressed. An echocardiographic study was performed after cardiopulmonary bypass, at discharge, and at follow-up. Cardiopulmonary bypass time was 32 +/- 6.3 minutes and crossclamp time was 23 +/- 7.4. There was no hospital mortality or morbidity. Intraoperative transesophageal and predischarge transthoracic echocardiography showed perfect results in all patients. No late deaths occurred. At the latest follow-up, extending to 14.2 months (mean 11.3; median 12.4), all patients were asymptomatic (New York Heart Association class I) with trivial (2 patients) or no residual regurgitation (3 patients) on 2-dimensional echocardiogram. No transvalvular gradient was revealed in any patient. A significant reduction of the right ventricular end-diastolic dimensions was noted as well (from 54 +/- 7.1 mm to 40 +/- 7.5 mm, P tricuspid valve repair in case of severe traumatic tricuspid valve insufficiency, leading to very satisfactory mid-term results even in the presence of complex lesions or dilatation and deterioration of the right ventricle.

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.

The acknowledgment of tricuspid regurgitation (TR) as a stand-alone and progressive entity, worsening the prognosis of patients whatever its aetiology, has led to renewed interest in the tricuspid-right ventricular complex. The tricuspid valve (TV) is a complex, dynamic and changing structure. As the TV is not easy to analyse, three-dimensional imaging, cardiac magnetic resonance imaging and computed tomography scans may add to two-dimensional transthoracic and transoesophageal echocardiographic data in the analysis of TR. Not only the severity of TR, but also its mechanisms, the mode of leaflet coaptation, the degree of tricuspid annulus enlargement and tenting, and the haemodynamic consequences for right atrial and right ventricular morphology and function have to be taken into account. TR is functional and is a satellite of left-sided heart disease and/or elevated pulmonary artery pressure most of the time; a particular form is characterized by TR worsening after left-sided valve surgery, which has been shown to impair patient prognosis. A better description of TV anatomy and function by multimodality imaging should help with the appropriate selection of patients who will benefit from either surgical TV repair/replacement or a percutaneous procedure for TR, especially among patients who are to undergo or have undergone primary left-sided valvular surgery.

Tricuspid valve (TV) regurgitation in congenital heart disease includes a heterogeneous group of lesions, and few series have documented the outcomes. We reviewed the records of 553 patients with congenital heart disease who had undergone TV surgery for tricuspid regurgitation from January 1993 to December 2010. Patients with Ebstein malformation were excluded. Their mean age was 32 ± 21 years, and 300 were female (54%). The most common diagnoses were conotruncal anomaly in 216 patients (39%), previous ventricular septal defect closure in 83 (15%), atrioventricular septal defect in 77 (14%), and pulmonary atresia with an intact ventricular septum in 11 (2%). Preoperative right-sided heart failure was present in 124 patients (22%), and 55 patients (10%) had pulmonary hypertension. TV repair was performed in 442 (80%) and TV replacement in 111 (20%) patients. Repeat sternotomy was performed in 415 patients (75%). Previous TV repair was present in 44 patients (8%); of these, 17 (38.6%) underwent repeat TV repair. The overall early mortality was 3.1% (17 patients) and was 2.5% for TV repair and 5.4% for TV replacement (P = .001). The mean follow-up period was 4.5 ± 4.1 years (maximum, 18). The overall survival at 1, 5, and 10 years was 97%, 93%, and 85%, respectively. Survival was better for patients with repair than with replacement. TV repair was an independent predictor of better survival (P = .001). Important tricuspid regurgitation can occur with a variety of congenital diagnoses. Early mortality is low and late survival is superior with tricuspid repair than with valve replacement. Surgical treatment of tricuspid regurgitation in congenital heart disease should be performed before the onset of heart failure. Copyright © 2014 The American Association for Thoracic Surgery.

The challenge of preoperative quantification of functional tricuspid regurgitation and of right ventricle function: what information is clinically relevant?

Science.gov (United States)

Hahn, Rebecca T

2017-10-01

Functional or secondary tricuspid regurgitation (TR) is the most common etiology of severe TR in the western world. The presence of functional TR, either isolated or in combination with left heart disease is associated with unfavorable natural history however surgical mortality for isolated tricuspid valve interventions remain higher than for any other single valve surgery. Determining the severity of TR remains a controversial area and will continue to evolve as new techniques for assessing this valve as well as the right ventricle, are investigated. The following review will describe tricuspid anatomy, define echocardiographic views for evaluating tricuspid valve and right heart morphology and function, that are relevant to the pre-procedural assessment of functional TR.

She was transferred for possible lung transplant and/or tricuspid valve surgery. Clinical and echocardiographic assessment provided confidence that acute tricuspid valve failure was responsible for the decompensation and that tricuspid valve replacement despite pulmonary hypertension could be performed.

Tricuspid valve regurgitation (TVR) in the orthotopic heart transplant (OHT) recipient is quite common and has varied clinical sequelae. In its severest forms, it can lead to right-sided failure symptoms indistinguishable from that seen in native heart TVR disease. While certain implantation techniques are widely recognized to reduce the risk of TVR in the cardiac allograft, concomitant tricuspid annuloplasty, while having advocates, is not currently accepted as a routinely established adjunct. Decisions to surgically correct TVR in the OHT recipient must be made carefully, as certain clinical scenarios have high risk of failure. Like in the native heart, anatomic etiologies typically have the greatest chances for success compared to functional etiologies. While repair options have been utilized, there is emerging data to support replacement as the more durable option. While mechanical prostheses are impractical in the heart transplant recipient, biologic valves offer the advantage of continued access to the right ventricle for biopsies in addition to acceptable durability in the low pressure system of the right side.

De Vega Annuloplasty for Functional Tricupsid Regurgitation: Concept of Tricuspid Valve Orifice Index to Optimize Tricuspid Valve Annular Reduction

We evaluated long-term results of De Vega annuloplasty measured by cylindrical sizers for functional tricuspid regurgitation (FTR) and analyzed the impact of measured annular size on the late recurrence of tricuspid valve regurgitation. Between 2001 and 2011, 177 patients (57.9±10.5 yr) underwent De Vega annuloplasty for FTR. Three cylindrical sizers (actual diameters of 29.5, 31.5, and 33.5 mm) were used to reproducibly reduce the tricuspid annulus. Long-term outcomes were evaluated and risk factor analyses for the recurrence of FTR ≥3+ were performed. Measured annular diameter indexed by patient's body surface area was included in the analyses as a possible risk factor. Operative mortality occurred in 8 patients (4.5%). Ten-year overall and cardiac death-free survivals were 80.5% and 90.8%, respectively. Five and 10-yr freedom rates from recurrent FTR were 96.5% and 93.1%, respectively. Cox proportional hazard model revealed that higher indexed annular size was the only risk factor for the recurrence of FTR (P=0.006). A minimal P value approach demonstrated that indexed annular diameter of 22.5 mm/m2 was a cut-off value predicting the recurrence of FTR. De Vega annuloplasty for FTR results in low rates of recurrent FTR in the long-term. Tricuspid annulus should be reduced appropriately considering patients' body size to prevent recurrent FTR.

Tricuspid regurgitation is relatively common. Due to the progress made in echocardiography, its diagnosis is in general made readily and in reliable fashion. Basically one has to distinguish between functional tricuspid valve regurgitation due to volume and/or pressure overload of the right ventricle with intact valve structures versus tricuspid valve regurgitation due to pathologic valve structures. The clear identification of the regurgitation mechanism is of prime importance for the treatment. Functional tricuspid valve regurgitation can often be improved by medical treatment of heart failure, and eventually a tricuspid valve plasty can solve the problem. However, the presence of pathologic tricuspid valve structures makes in general more specific plastic surgical procedures and even prosthetic valve replacements necessary. A typical example for a structural tricuspid valve regurgitation is the case of a traumatic papillary muscle rupture. Due to the sudden onset, this pathology is not well tolerated and requires in general surgical reinsertion of the papillary muscle. In contrast, tricuspid valve regurgitation resulting from chronic pulmonary embolism with pulmonary artery hypertension, can be improved by pulmonary artery thrombendarteriectomy and even completely cured with an additional tricuspid annuloplasty. However, tricuspid regurgitations due to terminal heart failure are not be addressed with surgery directed to tricuspid valve repair or replacement. Heart transplantation, dynamic cardiomyoplasty or mechanical circulatory support should be evaluated instead.

fever. The clinical findings were tachycardia with irregular pulse, right heart failure and regurgitant tricuspid murmur that increased with inspiration. The chest radiograph and the echocardiogram showed right ventricular dilatation and severe tricuspid regurgitation without pulmonary hypertension. The treatment with propranolol, corticosteroids and diuretics was successful. The patient was asymptomatic with sinus rhythm. We discuss the effects of thyroidal hormones on the cardiovascular system and postulate pathophysiologic mechanisms of heart failure in hyperthyroidism.

State-of-the-Art Review of Echocardiographic Imaging in the Evaluation and Treatment of Functional Tricuspid Regurgitation.

Functional or secondary tricuspid regurgitation (TR) is the most common cause of severe TR in the Western world. The presence of functional TR, either isolated or in combination with left heart disease, is associated with unfavorable natural history. Surgical mortality for isolated tricuspid valve interventions remains higher than for any other single valve surgery, and surgical options for repair do not have consistent long-term durability. In addition, as more patients undergo transcatheter left valve interventions, developing transcatheter solutions for functional TR has gained greater momentum. Numerous transcatheter devices are currently in early clinical trials. All patients require an assessment of valve morphology and function, and transcatheter devices typically require intraprocedural guidance by echocardiography. The following review will describe tricuspid anatomy, define echocardiographic views for evaluating tricuspid valve morphology and function, and discuss imaging requirements for the current transcatheter devices under development for the treatment of functional TR. © 2016 American Heart Association, Inc.

Contemporary management of tricuspid regurgitation: an updated clinical review.

2013-01-01

Tricuspid regurgitation (TR) is a complex and insidious valvular pathology that represents a complex decision and management algorithm for patients. TR is present in a significant proportion of the population and is especially prevalent in patients with advanced heart failure. Patients with TR have been demonstrated to have a decreased survival even with normal left heart function. TR can be a result of pathology that directly affects the valvular structure (i.e., Ebstein anomaly) or as a result of increased forward pressures (ie, pulmonary hypertension, left heart failure). Conservative management of patients with TR is primarily symptomatic relief. Definitive therapy involves surgical repair of the tricuspid valve. Furthermore, as more patients develop advanced heart failure, the management of TR in patients with left ventricular assist devices has become necessary because of the evidence of increased in-hospital morbidity and a trend toward decreased survival.

Patients with Ehlers-Danlos syndrome (EDS) type IV, an inherited connective tissue disorder, are predisposed to vascular and digestive ruptures, and arterial ruptures account for the majority of deaths. A 31-year-old man with EDS presented with an intramural aortoatrial fistula, severe aortic regurgitation, mitral valve prolapse, and severe tricuspid valve insufficiency combined with a severely dilated left ventricle. Determining the best surgical option for the patient was not easy, especially regarding the course of action for the aortic root with a tear in the sinus of Valsalva. The fistula tract was closed at the aorta with suture and with a patch in the right atrium, the mitral valve was repaired with edge-to-edge suture and then annuloplasty with a Cosgrove ring, the aortic valve was replaced with a mechanical prosthesis, and a modified De Vega technique was used for the tricuspid valvuloplasty. The postoperative course was uncomplicated, and the patient was discharged 2 weeks later. The considerations made to arrive at the chosen surgical course of action in this complex case are reviewed.

The purpose of this study was to prospectively determine the incidence of diastolic mitral and tricuspid regurgitation in atrioventricular (AV) block using Doppler echocardiography. The temporal relation between mitral and tricuspid diastolic insufficiency and the diastolic murmur recorded in patients with complete heart block was also investigated. Twenty-two consecutive patients with AV block (referred to the Echo-Doppler laboratory for routine clinical studies), aged 18 to 87 years, were enrolled in the study. Eleven patients had third degree AV block and a ventricular-inhibited (VVI) pacemaker, two patients had second degree AV block, seven patients had first degree AV block, one patient had blocked premature atrial complexes and one patient had atrial flutter with 4:1 AV block. Diastolic mitral regurgitation was detected in 20 patients, and diastolic tricuspid regurgitation in 21. A mid-diastolic murmur was detected in all patients except in the three youngest. The murmur occurred before diastolic regurgitation and coincided with peak forward flow through the AV valve after atrial contraction. M-mode mitral valve echocardiograms obtained in nine patients demonstrated near closure of some portions of the mitral valve after atrial contraction. Effective closure of the valve, however, did not occur unless ventricular systole supervened. In conclusion, diastolic mitral and tricuspid regurgitation are almost universally present in patients with AV block and are associated with a diastolic murmur. The murmur coincides with forward AV valve flow. Diastolic regurgitation is silent. Effective AV valve closure is not established until ventricular systole occurs, as demonstrated by M-mode echocardiographic recording of the mitral valve.

Functional tricuspid regurgitation (FTR) is common in patients with advanced heart failure and frequently complicates left ventricular assist device implantation yet remains poorly understood. We set out to establish large animal model of FTR that could serve as a research platform to investigate the pathogenesis of FTR associated with end-stage heart failure. : Through right thoracotomy, ten adult sheep underwent implantation of pacemaker with epicardial LV lead, five sonomicrometry crystals on the right ventricle, and left and right ventricular telemetry pressure sensors during a beating heart off-pump procedure. After 5 ± 1 days of recovery, baseline haemodynamic, echocardiographic and sonomicrometry data were collected. Animals were paced thereafter at a rate of 220-240 beats/min until the development of heart failure and concomitant tricuspid regurgitation. : Three animals died during early recovery period and one during the pacing phase. Six surviving animals were paced for a mean of 14 ± 5 days. Cardiac function was significantly depressed compared to baseline, with LV ejection fraction falling from 69 ± 2% to 22 ± 4% ( P  tricuspid annulus (from 29.5 ± 1.6 to 36.5 ± 4.5 mm; P  = 0.01) and right ventricle (from 21.9 ± 0.2 to 30.3 ± 0.6 mm; P  = 0.03).

Full Text Available Despite advanced sterile techniques in cardiac device implantations, long-term complications such as wound infections and/or lead-induced endocarditis can develop mandating lead and device extraction. It has been suggested that lead extraction carries a risk of new-onset Tricuspid Regurgitation (TR, or a deterioration of a formerly known regurgitant valve. Yet, there is no enough scientific evidence to our knowledge to back this claim. In this study we aim to explore the risk of TR following lead extraction.We conducted a retrospective chart review in 113 patients whom underwent lead extraction at Prince Sultan Cardiac Center in Saudi Arabia during the period of Jan, 2002 to Jul, 2015. Six patients underwent lead extraction twice, making the total number of extractions to be 119. Of this study cohort, we include 52 cases who had Tricuspid valve function evaluation via Transthoracic Echocardiography (TTE prior to and after device and lead extraction. TR severity was assessed using a grading system as the following; normal, mild, mild-to-moderate, moderate-to-severe, and severe. Worsening or improvement by more than 1 grade was considered clinically significant. TR following lead extraction was examined over a median of 5 months. Of the 52 cases included in this study, 37 (71.2% were males and 15 (28.8% were females, with a mean age of 46 (SD = 18 years. Eleven patients (21.2% experienced worsening of TR (3 had normal functioning valves before extraction, and 8 were known to have TR prior to extraction, 2 (3.8% had improvement, and the majority (75.0% did not experience any significant changes. Compared with those who had no change, average lead duration was higher in the worsening TR group (67.2 vs. 27.9 months. A lead-attached vegetation was detected in 4 out of the 11 patients with TR. Lead type (High-voltage vs. Pacing was not predictive of TR, 5 (45.5% of the patients in the worsening group had high-voltage leads, while the remaining (54

This study reviews our experience with traumatic tricuspid insufficiency (TTI) following blunt chest trauma. From January 2010 to June 2016, 10 patients (nine males, mean age 49.0 ± 12.4 years) underwent surgical treatment of TTI following blunt chest trauma. The mean intervals between trauma and diagnosis and between trauma and surgery were 74.1 and 81.8 months, respectively. Preoperatively, all patients exhibited severe tricuspid regurgitation. Five patients underwent tricuspid valve repair, and the remaining patients underwent valve replacement. The mean follow-up duration (with echocardiography) was 29.7 months. There was no early or late death. Seven patients had anterior chordal rupture, two patients had anterior papillary muscle rupture, and one patient had both anterior chordal and anterior leaflet rupture. The median postoperative intensive care unit and hospital stays were 1 and 6 days, respectively. There were no severe postoperative complications. During follow-up, four patients exhibited trivial to mild tricuspid regurgitation, and the remaining six patients exhibited no regurgitation. Surgical treatment of TTI via either valve repair or replacement can be performed with low perioperative morbidity and mortality. Early surgery is recommended for achieving a successful valve repair and preserving right ventricular function. © 2017 Wiley Periodicals, Inc.

Tricuspid valve regurgitation is frequently found as a result of right ventricular remodeling due to advanced left heart diseases. Drug treatment is limited to diuretics and the cardiac or pulmonary comorbidities. Due to the high risk only a small percentage of patients are amenable to surgical treatment of tricuspid regurgitation in those who undergo left-sided surgery for other reasons. Catheter-based procedures are an attractive treatment alternative, particularly since the strong prognostic impact of tricuspid regurgitation suggests an unmet need of treatment, independent of the underlying heart disease. A vast amount of clinical experience exists for the MitraClip system for treatment of mitral regurgitation. A first case series shows that the application for treatment of tricuspid regurgitation is technically feasible, seems to be safe and the degree of valve regurgitation can be reduced. In this review the background of tricuspid regurgitation treatment is summarized and first experiences and perspectives with the MitraClip system are assessed.

Estimation of left-sided valvular insufficiency has been obtained using the ratio of left- to right-ventricular stroke counts, i.e., the regurgitant index. The present study was designed to evaluate the usefulness of the regurgitant index in identifying patients with isolated right-sided valvular insufficiency. We identified 12 patients with tricuspid or pulmonic regurgitation by at least two of the following criteria: (1) pulsatile liver, (2) positive Carvallo's sign, and (3) pulsatile jugular-venous distension. In 9 of the 12 patients, the right-sided insufficiency was confirmed by catheterization or contrast echocardiography and flow-directed pulsed-echo Doppler. The regurgitant index in patients with right-sided insufficiency was 0.59 +- 0.23. This was significantly different from patients with left-sided insufficiency (3.09 +- 0.8) and from control subjects (1.49 +- 0.32). In 11 of the 12 patients with right-sided regurgitant lesions, the regurgitant index was less than 1.0. The hepatic expansion fraction, a possible correlate of an expansile liver, has previously been found to be both sensitive and specific for the detection of patients with right-sided regurgitation. We calculated the hepatic expansion fraction in 6 patients with tricuspid regurgitation (including 3 with pulsatile livers) and 5 controls using the method of Handler et al.. In the present study, the hepatic expansion fraction in tricuspid-insufficiency patients was 4.3% as compared to 4.1% in normals (P=NS). In summary, this study suggests that the regurgitant index may be a sensitive tool for the diagnosis of right-sided regurgitant lesions, while the hepatic expansion fraction does not appear to be useful for identifying tricuspid insufficiency.

In pediatric heart transplantation, the size of the donor organ is an important criterion for organ allocation. Oversized donor hearts are often accepted with good results, but some complications in relation to a high donor-recipient ratio have been described. Our patient was transplanted for progressive heart failure in dilated cardiomyopathy. The donor-to-recipient weight ratio was 3 (donor weight 65 kg, recipient weight 22 kg). The intra-operative echocardiography before chest closure showed excellent cardiac function, no tricuspid valve regurgitation, and a normal central venous pressure. After chest closure, central venous pressure increased substantially and echocardiography revealed a severe tricuspid insufficiency. As other reasons for right ventricular dysfunction, that is, myocardial ischemia, pulmonary hypertension, and rejection, were excluded, we assumed that the insufficiency was caused by an alteration of the right ventricular geometry. After 1 week, the valve insufficiency regressed to a minimal degree. In pediatric heart transplant patients with a high donor-to-recipient weight ratio, the outlined complication may occur. If other reasons for right ventricular heart failure can be ruled out, this entity is most likely caused by an acute and transient alteration of the right ventricular geometry that may disappear over time. © 2016 John Wiley & Sons A/S.

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

Right-sided cardiac valvular diseases have traditionally been considered less important than disease of mitral or aortic valve. However, severe tricuspid regurgitation could lead to right ventricle dysfunction and reduce patients' survival rate. In clinic setting, tricuspid valve disease should be paid more attention for patients with secondary tricuspid regurgitation caused by left-sided valvular surgery combined with irreversible annular dilatation increasing the risk of reoperation. In this review, we summarize the epidemiology, anatomy, pathology, diagnosis, ultrasound and cardiac magnetic resonance imaging findings in patients with tricuspid regurgitation.

The HeartMate II (Thoratec Corp, Pleasanton, Calif) continuous-flow left ventricular assist device has emerged as the standard of care for patients with advanced heart failure. The objective of this study was to assess the safety and early effectiveness of concomitant tricuspid valve procedures in patients undergoing implantation of a HeartMate II device. From February 2007 to April 2010, 83 patients underwent HeartMate II left ventricular assist device implantation. Of these, 37 patients had concomitant tricuspid valve procedures (32 repairs, 5 replacements) for severe tricuspid regurgitation. The effects of a tricuspid valve procedure on tricuspid regurgitation and right ventricular remodeling were assessed comparing echocardiographic findings at baseline and 30 days after left ventricular assist device implantation. Overall survival was also compared. Patients undergoing a concomitant tricuspid valve procedure had more tricuspid regurgitation (vena contracta, 5.6 ± 2.1 mm vs 2.9 ± 2.0 mm; P tricuspid regurgitation was worse in patients who underwent left ventricular assist device implantation alone (+18.6%), whereas it improved significantly in patients undergoing a concomitant tricuspid valve procedure (-50.2%) (P = .005). A corresponding significant reduction in right ventricular end-diastolic area (33.6% ± 6.2% vs 30.1% ± 9.7%; P = .03) and a trend toward better right ventricular function (55.5% ± 79.7% vs 35.7% ± 60.5%; P = .28) were noted in patients undergoing a concomitant tricuspid valve procedure. Survival was comparable between the 2 groups. In patients with severe tricuspid regurgitation undergoing left ventricular assist device implantation, a concomitant tricuspid valve procedure effectively reduces tricuspid regurgitation and promotes reverse remodeling of the right ventricle.

AIM: To assess whether the early regurgitation of intravenous contrast medium into the inferior vena cava (IVC) and/or hepatic veins on computed tomography (CT), indicates tricuspid regurgitation (TR), and if so, whether it be used to grade severity. MATERIALS AND METHODS: We identified 86 consecutive patients that had been investigated for possible pulmonary endarterectomy at Papworth Hospital. From these, 61 patients were selected in whom CT, transthoracic echocardiography, and right heart catheterization (RHC) had been performed within 6 weeks. Using an arbitrary visual scale, the degree of TR assessed by intravenous contrast-enhanced CT was compared with echocardiography. Results were analysed using a kappa weighted statistical test. In addition, CT and echocardiographic assessments of TR severity were correlated with pulmonary artery pressure measurements obtained by RHC (Spearman's rank correlation coefficient). RESULTS: CT assessment of TR had a sensitivity of 90.4% and a specificity of 100% in detecting echocardiographic TR. For TR graded as more than trivial by echocardiography, sensitivity of CT was 100%. With respect to RHC data, the correlation between severity assessment of TR between CT and echocardiography using the Kappa weighted coefficient was 0.56 (moderately good agreement). With respect to RHC data, the correlation between mean pulmonary pressure and TR grading on CT and echocardiography was r=0.685 (p<0.001) and r=0.727 (p<0.001), respectively. CONCLUSION: Early opacification of the IVC or hepatic veins on first-pass contrast-enhanced CT almost invariably indicates TR. There is moderately good agreement between CT and echocardiographic assessment of the severity of TR. Both CT and echocardiographic grading of TR correlate well with RHC measurements of pulmonary artery pressure

The authors report two cases of tricuspid regurgitation by a ruptured anterior papillary muscle secondary to non-penetrating thoracic trauma. In the presence of suggestive clinical and electrocardiographic abnormalities (systolic murmur, right heart failure, right bundle branch block), echocardiography confirmed the tricuspid regurgitation, showed its mechanism and excluded any other intracardiac lesions. Tricuspid annuloplasty was performed in both cases because of the persistence of failure or degradation of the patient's clinical condition. Peroperative echocardiography was used to judge the quality of the surgical repair in both cases. Traumatic tricuspid regurgitation is a rare condition and the diagnosis is often delayed. Echocardiography is the investigation of choice and guides treatment which is essentially valvular repair in symptomatic patients.

In a retrospective series of 960 cases of tricuspid regurgitation studied by two-dimensional echocardiography 6 patients presented a systolic defect of valvular coaptation. The origin of this defect varied: one case was due to carcinoid, two to rheumatic cardiopathy, two to papyraceous right ventricle and one to sclerodermia associated with pulmonary arterial hypertension. The mechanism of the lacking coaptation varies according to the etiology: valvular retraction in carcinoid cardiopathy, right-ventricle dilatation, dilatation of the tricuspid ring and altered kinetics of the right ventricle in the other cases. Changed contractility of the right ventricle is the only element allowing to distinguish tricuspid regurgitation with and without a coaptation defect. Clinically this abnormality always points to an advanced stage of severe tricuspid regurgitation.

Outcomes of tricuspid valve replacement are poor, partly due to right heart remodelling. The research on its underlying mechanisms is hampered by a lack of animal models of tricuspid regurgitation (TR). Our objective was to create a reproducible and clinically compatible TR animal model to study right heart remodelling caused by TR. Fourteen juvenile male Beagle dogs were divided randomly into an intervention group (n = 11) and a sham-operated control group (n = 3). The intervention group underwent thoracotomy and right atrial incision following superior and inferior vena caval occlusion. The anterior leaflet, together with the chordae, of the tricuspid valve was resected in eight dogs ('one leaflet' group), whereas both anterior and posterior leaflets, together with the chordae, were resected in three dogs ('two leaflets' group). The right atrium and chest were then closed. The control group underwent the same procedure, except leaflet resection. One dog from the 'two leaflets' group and one control dog were sacrificed and autopsy was performed at 12 months post-surgery. All dogs survived over the 1-year observation period postoperatively. TR grade IV occurred immediately postoperatively in the 'one leaflet' group, and TR grade IV plus in the 'two leaflets' group. The overall procedure lasted 30-40 min, and the mean time of vena caval occlusion was 87 ± 10 s. Central venous pressure increased from 6 ± 1.2 at baseline to 13 ± 1.7 mmHg (P heart remodelling. © The Author 2015.

Patients with atrial fibrillation (AF) without structural heart diseases can show severe tricuspid regurgitation (TR), especially among aged people. The aim of this study was to clarify the actual management, prognosis, and prognostic factors for severe isolated TR associated with AF without structural heart diseases. We retrospectively investigated actual management in 178 consecutive patients with severe isolated TR associated with AF between 1999 and 2011 in our institution. Prognosis and its predictors were also investigated in 115 patients (68 persistent TR and 47 transient TR) who were followed-up for >1year. During the follow-up period (mean: 5.9years), event free rate from death due to right-sided heart failure (RHF) was 97% at 5years. Persistent TR was associated with higher risk of hospitalization due to RHF than transient TR (log-rank P=0.048) and death due to RHF were all seen in patients with persistent TR who experienced hospitalization due to RHF. Among patients with persistent TR, right ventricular outflow tract dimension >35.3mm, right atrial area >40.3cm 2 , and tenting height >2.1mm were associated with higher risk of hospitalization due to RHF (adjusted hazard ratio: 3.32, 3.83, and 2.89, respectively; P=0.003, 0.002, and 0.009, respectively). The prognosis of severe isolated TR associated with AF was good with a focus on cardiac death. However, the incidence of cardiac death increased among patients who experienced hospitalization due to RHF. Larger right ventricular outflow tract dimension, right atrial area and tenting height were predictors of hospitalization due to RHF. Copyright © 2017 Elsevier B.V. All rights reserved.

Elevated pulmonary artery systolic pressure (PASP) causes functional tricuspid valve insufficiency (TI). However, the differential contribution of pressure load and right ventricular (RV) dilatation is not well established. The study aim was to evaluate both variables in relation to TI. A cross-sectional study was performed of consecutive transthoracic echocardiographic studies of patients with pre-capillary pulmonary hypertension (PH). Both, demographic data and echocardiographic RV parameters were reviewed. TI was graded semi-quantitatively with color Doppler flow imaging. Trend analyses for TI severity (TI grade 0/4, 1/4, 2/4, 3/4, or 4/4) were performed. A proportional odds logistic regression analysis was carried out to identify independent predictors of TI severity. Eighty-one patients (56 females, 25 males; mean age 60 +/- 15 years) with pre-capillary PH were evaluated. Patients with more severe TI had a significantly lower body mass index, a lower mean systemic blood pressure, a shorter pulmonary acceleration time, a higher tricuspid regurgitant gradient, and a more dilated right ventricle. From the echocardiographic parameters, RV dilatation (p = 0.0143) and the tricuspid regurgitant gradient (p = 0.0026) were independently related to the degree of TI. In patients with pre-capillary PH, PASP and RV dilatation were both related to the increasing severity of TI. When focusing on TI to improve the prognosis of patients with pre-capillary PH, both PASP and RV dimensions should be taken into consideration.

Traumatic tricuspid insufficiency is a rare condition. The diagnosis is difficult because of the slow progression of this pathology and the presence of more clinically acute lesions. Non-penetrating chest trauma is responsible for 90% of cases. Echocardiography is the investigation of choice for assessing the mechanism of the tricuspid regurgitation and for diagnosing associated lesions. It should be performed systematically in patients with multiple trauma. The surgical indications are difficult to determine and depend on the patients' symptoms and the type of anatomical lesions. It should be undertaken before right ventricular myocardial dysfunction. Several techniques may be used from valvuloplasty to valve replacement mainly with bioprostheses in symptomatic patients.

The purpose of this study is to evaluate the association of tricuspid regurgitation (TR) severity with outcomes after transcatheter aortic valve replacement (TAVR). We analyzed data from 34,576 patients who underwent TAVR at 365 US hospitals from November 2011 through March 2015 submitted to The Society of Thoracic Surgeon/American College of Cardiology Transcatheter Valve Therapy Registry. We examined unadjusted mortality and heart failure readmission stratified by degree of preoperative TR and used multivariable models for 1-year mortality and heart failure readmission. Tricuspid regurgitation was present in 80% (n = 27,804) of TAVR patients, with mild TR in 56% (n = 19,393), moderate TR in 19% (n = 6687), and severe TR in 5% (n = 1,724). Increasing TR severity was associated with a number of comorbidities and The Society of Thoracic Surgeons predicted risk of mortality increased (p < 0.001): no TR (7.3 ± 5.4); mild TR (8.0 ± 5.7); moderate TR (9.6 ± 6.8); and severe TR (10.7 ± 7.4). In unadjusted analysis, moderate and severe TR were associated with increased use of cardiopulmonary bypass, longer intensive care unit and hospital stays, new dialysis, inhospital major adverse cardiac event, inhospital mortality, observed-to-expected inhospital mortality ratio, long-term heart failure readmission, and mortality (p < 0.001). Adjusted mortality at 1 year was significantly worse for patients with severe TR when left ventricular ejection fraction greater than 30% (hazard ratio 1.29, 95% confidence interval: 1.11 to 1.50) as was heart failure readmission (hazard ratio 1.27, 95% confidence interval: 1.04 to 1.54). Tricuspid regurgitation was common among patients undergoing TAVR. Increasing TR severity was associated with higher risk patients and increased mortality and readmission-particularly for patients with severe TR and left ventricular ejection fraction greater than 30%.

A 39-year-old male who had undergone tricuspid valve replacement for severe tricuspid regurgitation was admitted with palpitation and general edema. Two-dimensional (2D) echocardiography showed tricuspid prosthetic valve dysfunction. Additional three-dimensional (3D) transthoracic and transesophageal echocardiography (TEE) could clearly demonstrate the disabilities of the mechanical tricuspid valve. Particularly, 3D TEE demonstrated a mass located on the right ventricular side of the tricuspid prosthesis, which may have caused the stuck disk. This observation was confirmed by intra-operative findings.

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.

Functional tricuspid regurgitation is caused by annular dilation mainly in the posterior annulus. However, ring annuloplasty does not always prevent the recurrence of tricuspid regurgitation due to dilation of the septal annulus. We developed a septal plication technique with a 3-dimensional MC3 ring. Between 2006 and 2011, 76 patients (male/female 30/46; mean age 68 ± 11 years) with functional tricuspid regurgitation received tricuspid ring annuloplasty. After placement of the annular sutures, the 3 commissural ring portions were fixed on the equivalent commissures to plicate the anterior and posterior annulus. The end of the septal ring portion was fixed at the optimal annular position to obtain minimal tricuspid regurgitation. All patients were followed-up for a mean of 47 ± 18 months; the longest duration was 79 months. Although there was no operative death, one patient died of sepsis during hospitalization (hospital mortality 1.3%). After implantation of the MC3 ring (mean size 31.0 ± 3.3 mm), additional edge-to-edge sutures were required for minor leakage in 5 (7%) patients. The degree of tricuspid regurgitation was significantly reduced at discharge (0.5 ± 0.6) and midterm (0.6 ± 0.6) compared to 2.5 ± 0.7 before the operation (p tricuspid ring annuloplasty with a 3-dimensional MC3 ring. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Quantitation of regurgitation severity using the proximal isovelocity acceleration (PISA) method to calculate effective regurgitant orifice (ERO) area has limitations. Measurement of three-dimensional (3D) vena contracta area (VCA) accurately grades mitral regurgitation (MR) severity on transthoracic echocardiography (TTE). We evaluated 3D VCA quantitation of regurgitant jet severity using 3D transesophageal echocardiography (TEE) in 110 native mitral, aortic, and tricuspid valves and six prosthetic valves in patients with at least mild valvular regurgitation. The ASE-recommended integrative method comprising semiquantitative and quantitative assessment of valvular regurgitation was used as a reference method, including ERO area by 2D PISA for assigning severity of regurgitation grade. Mean age was 62.2±14.4 years; 3D VCA quantitation was feasible in 91% regurgitant valves compared to 78% by the PISA method. When both methods were feasible and in the presence of a single regurgitant jet, 3D VCA and 2D PISA were similar in differentiating assigned severity (ANOVAP<.001). In valves with multiple jets, however, 3D VCA had a better correlation to assigned severity (ANOVAP<.0001). The agreement of 2D PISA and 3D VCA with the integrative method was 47% and 58% for moderate and 65% and 88% for severe regurgitation, respectively. Measurement of 3D VCA by TEE is superior to the 2D PISA method in determination of regurgitation severity in multiple native and prosthetic valves. © 2017, Wiley Periodicals, Inc.

Little is known on the clinical course of tricuspid regurgitation (TR) in patients with repaired tetralogy of Fallot (rTOF) and which patients are at particular risk. This study aims to determine TR course, characteristics associated with TR progression, and the prognostic relevance of TR in rTOF patients. In this dualcenter cohort study, rTOF patients from a prospective national registry with ≥1 cardiac magnetic resonance imaging study and ≥2 echocardiograms available were included. Clinical and imaging data were collected. Cox hazards regression analysis was used to assess patient characteristics associated with progression to severe TR and whether severe TR was associated with the combined clinical endpoint of tachyarrhythmia, heart failure, and death, as time-dependent factor. A total of 216 patients were included (57% men, age 34±12years); 11 patients (5%) had severe TR at baseline. During 7.6±3.5years of follow-up, progression to severe TR occurred in 15 patients (7%). NYHA class ≥2 (HR 5.38, 95%-C.I. 1.91-15.16, p=0.001) and moderate baseline TR (HR 13.10, 95%-C.I. 2.95-58.21, p=0.001) were independently associated with progression to severe TR. Adverse events occurred in 47 patients (22%). The occurrence of severe TR was independently associated with adverse events (HR 3.48, 95%-C.I. 1.68-7.21, p=0.001). In this study, severe TR was present in 12% of adult rTOF patients during 7.6years, and progression to severe TR was most likely in symptomatic patients with moderate baseline TR. In these patients, close surveillance is warranted, because the occurrence of severe TR was associated with worse prognosis. Copyright © 2017 Elsevier B.V. All rights reserved.

Open heart surgery is commonly associated with cardiopulmonary bypass and cardioplegic arrest. The attendant risks of cardiopulmonary bypass may be prohibitive in high-risk patients. We present a novel endoscopic technique of performing tricuspid valve repair without cardiopulmonary bypass in a beating ovine heart. Six sheep underwent sternotomy and creation of a right heart shunt to eliminate right atrial and right ventricular blood for clear visualization. The superior vena cava, inferior vena cava, pulmonary artery, and coronary sinus were cannulated, and the blood flow from these vessels was shunted into the pulmonary artery via a roller pump. The posterior leaflet of the tricuspid valve was partially excised to create tricuspid regurgitation, which was confirmed by Doppler echocardiography. A 7.0-mm fiberoptic videoscope was inserted into the right atrium to visualize the tricuspid valve. Under cardioscopic vision, an endoscopic needle driver was inserted into the right atrium, and a concentric stitch was placed along the posterior annulus to bicuspidize the tricuspid valve. Doppler echocardiography confirmed reduction of tricuspid regurgitation. All animals successfully underwent and tolerated the surgical procedure. The right heart shunt generated a bloodless field, facilitating cardioscopic tricuspid valve visualization. The endoscopic stitch resulted in annular plication and functional tricuspid valve bicuspidization, significantly reducing the degree of tricuspid regurgitation. Cardioscopy enables less invasive, beating-heart tricuspid valve surgery in an ovine model. This technique may be useful in performing right heart surgery without cardiopulmonary bypass in high-risk patients.

To analyze the feasibility, safety and effectiveness of Tricuspid valve (TV) repair using the MitraClip system in patients at high surgical risk. Forty-two elderly high-risk patients (76.8±7.3 years, EuroScore II 8.1±5.7) with isolated TR or combined TR and mitral regurgitation (MR) underwent edge-to-edge repair of the TV (n=11) or combined edge-to-edge repair of the TV and mitral valve (n=31). Procedural details, success rate, impact on TR severity and predictors for success at 30 day follow-up were analyzed. Successful edge-to-edge repair of TR was achieved in 35/42 patients (83%, 68 clips in total, 94% in the anteroseptal commissure, 6% in the posteroseptal commissure). In 5 patients, grasping of the leaflets was impossible and two patients had no decrease in TR after clipping. In those with procedural success, clipping of the TV led to a reduction in effective regurgitant orifice area by -62,5 % (from 0.8±0.4 to 0.3±0.2 cm2; pEdge-to-edge repair of the TV is feasible with promising reduction in TR, which could result in clinical improvement.

A case is presented in which a portable nuclear scintillation probe was used to detect tricuspid regurgitation. An electrocardiographically-gated scintigraphic collection obtained over the liver was correlated with findings from contrast echocardiography and jugular venous pulse tracings. The nuclear probe may provide a simple means for the detection of tricuspid insufficiency. It remains to be determined if quantification of severity will be possible

Pledget-assisted suture tricuspid valve annuloplasty (PASTA) is a novel technique using marketed equipment to deliver percutaneous trans-annular sutures to create a double-orifice tricuspid valve. Tricuspid regurgitation is a malignant disease with high surgical mortality and no commercially available transcatheter solution in the US. Two iterations of PASTA were tested using trans-apical or trans-jugular access in swine. Catheters directed paired coronary guidewires to septal and lateral targets on the tricuspid annulus under fluoroscopic and echocardiographic guidance. Guidewires were electrified to traverse the annular targets and exchanged for pledgeted sutures. The sutures were drawn together and knotted, apposing septal and lateral targets, creating a double orifice tricuspid valve. Twenty-two pigs underwent PASTA. Annular and chamber dimensions were reduced (annular area, 10.1 ± 0.8 cm 2 to 3.8 ± 1.5 cm 2 (naïve) and 13.1 ± 1.5 cm 2 to 6.2 ± 1.0 cm 2 (diseased); septal-lateral diameter, 3.9 ± 0.3 mm to 1.4 ± 0.6 mm (naïve) and 4.4 ± 0.4 mm to 1.7 ± 1.0 mm (diseased); and right ventricular end-diastolic volume, 94 ± 13 ml to 85 ± 14 ml (naïve) and 157 ± 25 ml to 143 ± 20 ml (diseased)). MRI derived tricuspid regurgitation fraction fell from 32 ± 12% to 4 ± 5%. Results were sustained at 30 days. Pledget pull-through force was five-fold higher (40.6 ± 11.7N vs 8.0 ± 2.6N, P PASTA reduces annular dimensions and tricuspid regurgitation in pigs. It may be cautiously applied to selected patients with severe tricuspid regurgitation and no options. This is the first transcatheter procedure, to our knowledge, to deliver standard pledgeted sutures to repair cardiac pathology. Published 2018.

Background: Velocity-encoding is used to quantify tricuspid regurgitation (TR) by cardiovascular magnetic resonance (CMR), but requires additional dedicated imaging. We hypothesized that size and signal intensity (SI) of the cross-sectional TR jet area in the right atrium in short-axis steady-state free-precession images could be used to assess TR severity. Methods: We studied 61 patients with TR, who underwent CMR and echocardiography within 24 h. TR severity was determined by vena contracta: severe (N = 20), moderate or mild (N = 41). CMR TR jet area and normalized SI were measured in the plane and frame that depicted maximum area. ROC analysis was performed in 21/61 patients to determine diagnostic accuracy of differentiating degrees of TR. Optimal cutoffs were independently tested in the remaining 40 patients. Results: Measurable regions of signal loss depicting TR jets were noted in 51/61 patients, while 9/10 remaining patients had mild TR by echocardiography. With increasing TR severity, jet area significantly increased (15 ± 14 to 38 ± 20 mm{sup 2}), while normalized SI decreased (57 ± 27 to 23 ± 11). ROC analysis showed high AUC values in the derivation group and good accuracy in the test group. Conclusion: TR can be quantified from short-axis CMR images in agreement with echocardiography, while circumventing additional image acquisition.

Post-traumatic tricuspid insufficiency is a rare complication of chest trauma. An 18-year-old male patient was injured in a bicycle accident from his abdominal and anterior chest wall. The tear on the inferior diaphragmatic surface of the heart was repaired with primary sutures by the attending surgeon. Eighteen years later, he was admitted to the hospital with severe tricuspid regurgitation (3+/4+). During the operation, the valve was determined unsuitable for repair and was replaced with a bioprosthesis. The hemodynamic aberrations relevant to an isolated tricuspid valve injury are very often well-tolerated. Reconstructive surgery may be possible in the early period. In the late cases, repair is sometimes not feasible due to degeneration of the valvular apparatus. Replacement with a biological prosthesis may give the best long-term results in longstanding cases.

INTRODUCTION : since tricuspid valve disease most often found in association with other valve disease. Isolated tricuspid valve disease is ra re. Pattern of involvement of tricuspid valve disease shows functional (75% and primary (organic in (25%. Surgical repair of organic tricuspid valve disease often fails because of abnormal valve. This usually leads to limited options. This study examine s our experience of tricuspid valve repair with autologous pericardium for organic tricuspid valve disease. MATERIAL AND METHODS : From Jan 2014 to May 2015, 22 patients underwent repairs for organic tricuspid valve disease. The patient aged 15 to 65 years and all were in New York Heart Association (NYHA class of III or IV. All patients presented with severe tricuspid disease coexisting with other cardiac pathology, usually left - sided heart valve disease. Repair techniques included Commisurotomy, division o f secondary chordae, Glutaraldehyde treated autologous pericardial patch augmentation of tricuspid valve leaflets, anterior papillary muscle advancement etc with or without ring/suture annuloplasty. Follow - up duration was 3 to 18 months. RESULTS : No deaths or late reoperations occurred. All patients demonstrated clinical improvements on follow up. Echocardiographic studies before hospital discharge showed less than mild tricuspid regurgitation in all patients except one. CONCLUSIONS : Large majorit y of organic tricuspid valve regurgitation is repairable with acceptable early results. Tricuspid stenosis and mixed tricuspid valve disease are more challenging. In the latter group, it is a judgment call whether to accept a suboptimal result or replace t he valve

Functional tricuspid regurgitation (FTR) commonly arises secondary to conditions affecting the left heart and is associated with right ventricular dysfunction and tricuspid annular dilatation. We set out to establish an animal model of acute RV failure (RVF) with FTR resembling the clinical features. Ten adult sheep had pressure sensors placed in the LV, RV, and right atrium while sonomicrometry crystals were implanted around tricuspid annulus and on the RV. Animals were studied open-chest to assess for RV function and FTR after: (1) volume infusion, (2) pulmonary artery constriction, (3) 5 min posterior descending artery occlusion, and (4) combination of all interventions. Hemodynamic, echocardiographic, and sonomicrometry data were collected at baseline and after every intervention. RV dimensions, RV strain, and annular area, perimeter, and size were calculated from crystal coordinates. The model was validated in six additional sheep studied only before and after combined interventions. Neither volume infusion, pulmonary hypertension, nor ischemia were associated with RVF or clinically significant TR when applied separately but combined resulted in RVF and greater than moderate FTR. In the validation group, maximal RV volume increased (62 ± 14 vs 70 ± 16 ml, p = 0.006), contractility decreased (20 ± 6 vs 12 ± 2%, p = 0.02), and strain increased. FTR increased from 0.4 ± 0.5 to 2.5 ± 0.8 (p < 0.001) and annular area from 652 ± 87 mm 2 to 739 ± 87 mm 2 (p = 0.005). The developed ovine model of acute RVF was associated with significant annular and RV enlargement and FTR. This novel and clinically pertinent research platform offers insight into the acute RVF pathophysiology and can be utilized to evaluate treatment interventions. Copyright © 2018 Elsevier B.V.

Tricuspid incompetence associated with a right ventricular aneurysm wa discovered after a non-penetrating thoracic injury. The severity of the tricuspid lesion was confirmed by phonomechanography, catheterisation and angiography. The mechanism was demonstrated by two-dimensional echocardiography: the right ventricular aneurysm was located in the right ventricular outflow tract. As the hemodynamic tolerance was good, surgery was not performed. A review of the literature found 41 other reports of traumatic tricuspid incompetence, and 4 cases of right ventricular aneurysm, only one of which was associated with tricuspid regurgitation. The points of interest of ths case: the rarity of the association, the good hemodynamic tolerance and the value of two-dimensional echocardiography for the diagnosis of ruptured chordae in the absence of surgical observations.

Libman-Sacks endocarditis, one of the most prevalent cardiac presentations of systemic lupus erythematosus, typically affects the aortic or mitral valve; tricuspid valve involvement is highly unusual. Secondary antiphospholipid syndrome increases the frequency and severity of cardiac valvular disease in systemic lupus erythematosus. We present the case of a 47-year-old woman with lupus and antiphospholipid syndrome whose massive tricuspid regurgitation was caused by Libman-Sacks endocarditis isolated to the tricuspid valve. In addition, we discuss this rare case in the context of the relevant medical literature.

We report the case of a 26-year old woman who underwent successful tricuspid valve repair for the absence of the anterior papillary of the tricuspid valve. Preoperative echocardiography revealed grade IV tricuspid valve regurgitation, caused by congenital absence of the anterior papillary muscle and prolapse of the anterior leaflet. Tricuspid valve repair was performed using artificial chords consisting of two polytetrafluoroethylene sutures and a concomitant ring annuloplasty. Postoperative echocardiography revealed mild tricuspid valve regurgitation. This approach represented a safe and effective technique for tricuspid valve repair in congenital absence of papillary muscle. © The Author 2016.

Tricuspid regurgitation (TR) is a very frequent manifestation of valvular heart disease. It may be due to the primary involvement of the valve or secondary to pulmonary hypertension or to the left-sided heart valve disease (most commonly rheumatic and involving the mitral valve). The pathophysiology of secondary TR is complex and is intrinsically connected to the anatomy and function of the right ventricle. A systematic multimodality approach to diagnosis and assessment (based not only on the severity of the TR but also on the assessment of annular size, RV function and degree of pulmonary hypertension) is, therefore, essential. Once considered non-important, treatment of secondary TR is currently viewed as an essential concomitant procedure at the time of mitral (and, less frequently, aortic valve) surgery. Although the indications for surgical management of severe TR are now generally accepted (Class I), controversy persists concerning the role of intervention for moderate TR. However, there is a trend for intervention in this setting, especially at the time of surgery for left-sided heart valve disease and/or in patients with significant tricuspid annular dilatation (Class IIa). Currently, surgery remains the best approach for the interventional treatment of TR. Percutaneous tricuspid valve intervention (both repair and replacement) is still in its infancy but may become a reliable option in future, especially for high-risk patients with isolated primary TR or with secondary TR related to advanced left-sided heart valve disease. © The Author 2017.

Evaluation of tricuspid incompetence has benefitted considerably from the development of Doppler ultrasound. In addition to direct analysis of the valves, which provides information about the mechanism involved, this method is able to provide an accurate evaluation, mainly through use of the Doppler mode. In addition to new criteria being evaluated (mainly the convergence zone of the regurgitant jet), some indices are recognised as good quantitative parameters: extension of the regurgitant jet into the right atrium, anterograde tricuspid flow, laminar nature of the regurgitant flow, analysis of the flow in the supra-hepatic veins, this is only semi-quantitative, since the calculation of the regurgitation fraction from the pulsed Doppler does not seem to be reliable; This accurate semi-quantitative evaluation is made possible by careful and consistent use of all the criteria available. The authors set out to discuss the value of the various evaluation criteria mentioned in the literature and try to define a practical approach.

The study aim was to assess the impact of reducing the right ventricular (RV) cavity in order to optimize the outcome of tricuspid valve (TV) repair in cases of functional tricuspid regurgitation (FTR) with dilated right ventricle. Between May 2007 and February 2010, a total of 17 patients (six males, 11 females; mean age 69.5 +/- 10.1 years; mean logistic EuroSCORE 24 +/- 13%) with severe FTR and severe RV dilation were included. Echocardiography and magnetic resonance imaging (MRI) were performed for geometric assessment of the right ventricle. Intraoperatively, the lateral RV free wall was plicated to reduce the RV cavum to approximate the papillary muscles and decrease tethering of the TV; a conventional ring annuloplasty was then performed. Follow up included echocardiography and MRI at one month and one year postoperatively. The mean operative time was 157 +/- 30 min, and the cross-clamp time 63 13 min. Postoperatively, the mean bleeding volume was 486 +/- 455 ml, the rethoracotomy rate 5.9%, intensive therapy unit (ITU) stay 6.0 +/- 4.4 days, and hospital stay 19.0 +/- 8.8 days. In-hospital mortality was 17.6%. The mean follow up was 14.4 +/- 2.4 months. The one-year follow up revealed a survival of 82.3%, a slight decrease in RV ejection fraction (from 33.5 +/- 4.2% to 31.7 +/- 5.7%; p = 0.13), a significant reduction in the RV end-diastolic volume index (from 160 +/- 15.6 to 128 +/- 10 ml/m2; p = 0.0001), a reduction in TV tenting area (from 3.3 +/- 0.9 to 0.9 +/- 0.3 cm2; p = 0.0001), and a significant reduction in the ratio of TR jet to right atrial surface area (from 54.8 +/- 8.2% to 14.1 +/- 3.5%; p = 0.0001). In cases of FTR, RV dilation may be considered as a correctable factor at subvalvular level to optimize the outcome of TV repair.

Seventy-eight patients undergoing mitral valve surgery with or without replacement of the aortic valve also underwent procedures on the tricuspid valve over a period of 10 years. All patients were in functional class III or IV preoperatively. The procedures were performed in all patients with organic disease of the tricuspid valve (N = 44) and in those with moderate or severe functional tricuspid valvar regurgitation (N = 34). Seventy-one patients underwent DeVega's annuloplasty with or without commissurotomy. The overall mortality was 11.5%. 65 long-term survivors were followed up for a period of 6 months to 10 years (mean 5.3 years). Sixty-three patients were in functional class I or II at the last follow-up. Six patients had clinical evidence of mild to moderate tricuspid regurgitation. Regression of cardiomegaly (as judged by the chest radiograph and right ventricular hypertrophy seen in the electrocardiogram) was evident in most cases. Fifty-one of 54 patients evaluated by cross-sectional echocardiography were reported to have a functionally normal tricuspid valve. Doppler echocardiography in 28 patients showed no significant tricuspid regurgitation or stenosis in 26 patients. Eleven consecutive patients undergoing DeVega's annuloplasty were studied prospectively with pre- and postoperative Doppler echocardiography. Good correlation existed between right ventricular systolic pressures predicted by Doppler with those obtained preoperatively at cardiac catheterization. Postoperative Doppler echocardiography in these 11 patients showed complete restoration of competence of the tricuspid valve as well as normalisation of the right ventricular systolic pressure in 10 patients.

We describe a case of a 50-year-old woman with congenitally corrected transposition of the great vessels, in whom severe left-sided tricuspid (systemic atrioventricular) valve insufficiency was the only associated anomaly. The tricuspid valve was dysplastic and abnormally oriented toward the interventricular septum, without the downward displacement of Ebstein's anomaly. The mechanism of atrioventricular regurgitation was unusual in that it consisted of the rupture of chordae tendineae of both the anterior and septal leaflets. The left-sided tricuspid valve was replaced with a St. Jude prosthesis and the postoperative course was uneventful.

Traumatic tricuspid insufficiency (TTI) is uncommon and surgical experience is limited. We report our surgical experience with TTI in 13 patients. From January 2000 through March 2008, we operated on 13 patients with TTI (10 men 3 women; mean age, 39.8 ± 10.5 years). The intervals from trauma to diagnosis and from trauma to surgery averaged 37.4 and 54.4 months, respectively. At operation, the mechanism of TTI was due to anterior chordal rupture in 8, anterior papillary muscle rupture in 3, rupture of anterior papillary muscle and chordae in 1, and anterior leaflet defect in 1. In 7 patients the annulus was dilated. Valve repair was successful in 13 patients. No early or late deaths occurred. Severe hemolysis occurred in 1 patient after tricuspid and mitral valve repairs. At follow-up extending to 9.5 years, 9 patients were in New York Heart Association functional class I, and 4 were in class II. Transthoracic echocardiography demonstrated no or trivial residual regurgitation in 7 patients, mild regurgitation in 4, and mild-to-moderate regurgitation in 2. A significant decrease of the right ventricular end-diastolic dimension (37.7 ± 9.7 vs 20.7 ± 4.6 mm; p tricuspid valve repair.

Tricuspid regurgitation (TR) and right ventricular (RV) dysfunction adversely affect outcomes in patients with heart failure or mitral valve disease, but their impact on outcomes in patients with aortic stenosis treated with transcatheter aortic valve replacement has not been well characterized. Among 542 patients with symptomatic aortic stenosis treated in the Placement of Aortic Transcatheter Valves (PARTNER) II trial (inoperable cohort) with a Sapien or Sapien XT valve via a transfemoral approach, baseline TR severity, right atrial and RV size and RV function were evaluated by echocardiography according to established guidelines. One-year mortality was 16.9%, 17.2%, 32.6%, and 61.1% for patients with no/trace (n=167), mild (n=205), moderate (n=117), and severe (n=18) TR, respectively (Pright atrial and RV enlargement were also associated with increased mortality (Pright atrial and RV enlargement, but not RV dysfunction. There was an interaction between TR and mitral regurgitation severity (P=0.04); the increased hazard of death associated with moderate/severe TR only occurred in those with no/trace/mild mitral regurgitation. In inoperable patients treated with transcatheter aortic valve replacement, moderate or severe TR and right heart enlargement are independently associated with increased 1-year mortality; however, the association between moderate or severe TR and an increased hazard of death was only found in those with minimal mitral regurgitation at baseline. These findings may improve our assessment of anticipated benefit from transcatheter aortic valve replacement and support the need for future studies on TR and the right heart, including whether concomitant treatment of TR in operable but high-risk patients with aortic stenosis is warranted.

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.

Functional tricuspid regurgitation (TR) with a structurally normal tricuspid valve (TV) may occur secondary to chronic atrial fibrillation (AF). However, the clinical and echocardiographic differences according to functional TR subtypes are unclear. Therefore, characterization of functional TR because of chronic AF (AF-TR) remains undetermined. To investigate the prevalence of AF-TR, 437 patients with moderate to severe TR underwent 3-dimensional (3D) transesophageal echocardiography. TR severity was determined by the averaged vena contracta width on apical and parasternal inflow views. The prevalence of AF-TR was 9.2%, whereas that of functional TR because of left-sided heart disease was 45.3%. Clinical features of AF-TR included advanced age, female sex, greater right atrial than left atrial enlargement and lower systolic pulmonary artery pressure compared with left-sided heart disease-TR with sinus rhythm (all P<0.05). In 3D TV assessment, patients with AF-TR had a larger TV annular area with weaker annular contraction (both P<0.001) but a smaller tethering angle (P<0.001) despite a similar leaflet coaptation status compared with patients with left-sided heart disease-TR with sinus rhythm. On multivariable analysis, only the TV annular area in midsystole (coefficient, 0.059; 95% confidence interval, 0.041-0.078 per 100 mm 2 ; P<0.001) was associated with TR severity in AF-TR. The annular area was more closely correlated with the right atrial volume than right ventricular end-systolic volume in AF-TR (P<0.001). AF-TR is not rare and is associated with advanced age and right atrial enlargement. TV deformations and their association with right heart remodeling differ between AF-TR and left-sided heart disease-TR. Our results suggest that in patients with TR secondary to AF, TV annuloplasty should be effective because this entity has annular dilatation without leaflet deformation. © 2017 American Heart Association, Inc.

Surgical techniques currently used for the repair of Ebstein's anomaly comprise reconstruction of the tricuspid valve mechanism at the level of the true annulus with or without plication of the atrialized right ventricle. However, performing this procedure for patients with a dysmorphic anterior leaflet (i.e., insufficient leaflet tissue and decreased mobility due to tethering) may necessitate technical modifications. A retrospective review was performed of 31 patients (seven males and 24 females, median age at operation 31 years) with Ebstein's anomaly, who underwent tricuspid valve repair between March 2002 and December 2014. The original Hetzer technique (annulus to annulus approximation) was employed for six patients with a well-formed anterior leaflet. In 25 patients, the tricuspid valve mechanism was restored at the displaced septal leaflet by approximating the anterior leaflet attachment in the true annulus to the displaced septal leaflet attachment in the mid-septum. A bidirectional superior cavopulmonary anastomosis was added in 27 of 31 (87%) patients. No early or late death occurred during the median follow-up of 66 months (1-138 months). Immediate postoperative tricuspid regurgitation was trivial to mild in 22 patients, and the median preoperative, immediate postoperative, and last follow-up tricuspid regurgitation jet areas in 21 adult patients were 23.3 cm2, 10.4 cm2, and 7.0 cm2, respectively. Two patients underwent reoperation at 81 and 119 months postoperatively. Five-year freedom from severe tricuspid regurgitation or reoperation was 93.2%. Restoration of the tricuspid valve mechanism at the level of displaced septal leaflet leads to excellent long-term outcomes. The addition of the bidirectional superior cavopulmonary anastomosis has contributed to the success of this technique. © 2016 Wiley Periodicals, Inc.

Background  Tricuspid regurgitation (TR) in patients undergoing surgery for mitral valve (MV) increases morbidity and mortality, especially in case of a poor right ventricle. Does repair of mild-to-moderate insufficiency of the tricuspid valve (TV) in patients undergoing MV surgery lead to a benefit in early postoperative outcome? Methods  A total of 22 patients with mild-to-moderate TR underwent MV repair and concomitant TV repair with Tri-Ad (Medtronic ATS Medical Inc., Minneapolis, Minnesota, United States) and Edwards Cosgrove (Edwards Lifesciences Irvine, California, United States) rings. The severity of TR was assessed echocardiographically by using color-Doppler flow images. The tricuspid annular plane systolic excursion (TAPSE) was under 1.7 cm. Additional procedures included coronary artery bypass ( n  = 9) and maze procedure ( n  = 15). The following parameters were compared: postoperative and peak dose of noradrenaline (NA), pre/postoperative systolic pulmonary pressure (sPAP), extubation time, operation time, cross-clamp time, cardiopulmonary bypass (CPB) time, pre/postoperative ejection fraction (EF), intensive care unit (ICU)-stay, hospital stay, cell saver blood transfusion, intra/postoperative blood transfusion, and postoperative TR. Results  The mean age was 67 ± 14.8 years, 45% were male. Mean EF was 47 ± 16.2%, postoperative 52 ± 12.4%. sPAP was 46 ± 20.1 mm Hg preoperatively, sPAP was 40.6 ± 9.4 mm Hg postoperatively, NA postoperatively was 12 ± 10 μg/min, NA peak was 18 ± 11 μg/min, operation time was 275 ± 92 minutes, CPB was 145 ± 49 minutes, ICU stay was 2.4 ± 2.4 days, hospital stay was 10.8 ± 3.5 days, cell saver blood transfusion was 736 ± 346 mL, intraoperative transfusions were 2.5 ± 1.6. Two patients needed postoperative transfusions. A total of 19 patients were extubated at the 1st postoperative day, 2 patients at the 2nd day, and 1 at the 4th

The emerging new treatment options for aortic valve disease call for more sophisticated diagnostics. We aimed to describe the echocardiographic pathophysiology and characteristics of the purely regurgitant aortic valve in detail. Twenty-nine men, with chronic aortic regurgitation without concomitant heart disease referred for aortic valve intervention, underwent 2D transoesophageal echocardiographic (TEE) examination prior to surgery according to a previously published matrix. Measurements of the aortic valve apparatus in long and short axis view were made in systole and diastole and analysed off-line. The aortic valves were grouped as tricuspid (TAV) or bicuspid (BAV), and classified by regurgitation mechanism. Twenty-four examinations were eligible for analysis of which 13 presented TAV and 11 BAV. The regurgitation mechanism was classified as dilatation of the aorta in 6 cases, as prolapse in 11 cases and as poor cusp tissue quality or quantity in 7 cases. The ventriculo-aortic junction (VAJ) and valve opening were closely related (TAV r = 0.5, BAV r = 0.73) but no correlation was found between the VAJ and the maximal sinus diameter (maxSiD) or the sinotubular junction (STJ). However, the STJ and maxSiD were significantly related (TAV vs BAV: systole r = 0.9, r = 0.8; diastole r = 0.9, r = 0.7), forming an entity. The conjoined BAV cusps were shorter than the anterior cusps when closed (P = 0.002); the inter-commissural distances of the cusps in the BAV group were significantly different (P = 0.001 resp. 0.03) in both systole and diastole. The VAJ was independent of other aortic dimensions and should thereby be considered as a separate entity with influence on valve opening. The detailed 2D TEE measurements of this study add further important information to our knowledge about the function and echocardiographic anatomy of the pathological aortic valve and root either as a stand-alone examination or as a benchmark and complement to 3D echocardiography.

This case report describes a toddler who developed a protein-losing enteropathy (PLE) 4 years after orthotopic heart transplantation (OHT). He was born with a hypoplastic left heart syndrome for which he underwent a successful Norwood procedure, a Hemi-Fontan palliation, and a Fontan palliation at 18 months of age. Fifteen months following the Fontan operation, he developed a PLE and Fontan failure requiring OHT. Four years after OHT, he developed a severe tricuspid regurgitation and a PLE. His PLE improved after tricuspid valve replacement. It is now 2 years since his tricuspid valve replacement and he remains clinically free of ascites and peripheral edema with a normal serum albumin level. His prosthetic tricuspid valve is functioning normally. © 2011 Wiley Periodicals, Inc.

Background To determine potential predictors of ventricular tachyarrhythmia and sudden cardiac death (SCD) occurring late after repair of tetralogy of Fallot (TOF). Methods Since 1964, 415 patients had undergone total repair for TOF at Niigata University Hospital. Of these, 89 patients who were followed for more than 10 years at our institute were retrospectively reviewed. Results The mean follow-up period was 24.3 years. During the study period, one patient died of cerebral bleeding, and two patients had SCD. The overall survival rates at 20, 30, and 40 years were 100%, 94.6%, and 94.6%, respectively. Eight (9.0%) patients required re-intervention during the late period associated with right ventricular outflow (n=4), tricuspid valve (n=3), aortic valve (n=2), and others (n=2). Ten (11.2%) patients had a history of ventricular tachycardia (VT) or ventricular fibrillation (VF), and six underwent implantation of an implantable cardiac defibrillator. Multivariate analysis selected the change rate of QRS duration [ms/year; odds ratio (OR), 2.44; 95% confidence interval (CI): 1.28–4.65; P=0.007] and the pressure gradient at tricuspid valve regurgitation on echocardiography (OR, 1.12; 95% CI: 1.02–1.22; P=0.017) as risk factors for VT/VF or SCD. Trans-annular patch (TAP) repair was not an independent risk factor for ventricular arrhythmia. Conclusions The combination of rapid change rate of QRS duration and higher-pressure gradient at tricuspid regurgitation were risk factors for ventricular tachyarrhythmia late after TOF repair. Adequate surgical or catheter intervention for pressure and volume load in the right ventricle might decrease the prevalence of VT/VF and SCD. PMID:29312717

Transcatheter approaches in heart valve disease became tremendously important and are currently established in the aortic position, but transcatheter tricuspid repair is still in its beginning and remains challenging. Replicating the surgical edge-to-edge technique, for example, with the MitraClip System (Abbott Vascular, Santa Clara, Calif), represents a promising option and has been reported successfully in small numbers of cases. However, up to now, few data considering the edge-to-edge technique as a transcatheter approach are available. This study aims to determine the ex vivo hydrodynamics after the central and paracommissural edge-to-edge technique in different pathologies. Because of basal or apical dislocation of papillary muscles, leaflet prolapse or tethering was simulated in porcine tricuspid valves mounted on a flexible holding device. Central and paracommissural edge-to-edge techniques were evaluated successively in these pathologies. Regurgitant volume and mean transvalvular gradient were determined in a pulse duplicator. In this ex vivo model, the isolated edge-to-edge technique reduced tricuspid regurgitation. In the prolapse model, regurgitant volume decreased significantly after central edge-to-edge technique (from 49.4 ± 13.6 mL/stroke to 39.3 ± 14.1 mL/stroke). In the tethering model, both the central and the paracommissural edge-to-edge techniques led to a significant decrease (from 48.7 ± 13.9 to 43.6 ± 15.6 and to 41.1 ± 13.8 mL/stroke). In all cases, the reduction of regurgitant volume was achieved at the cost of significantly increased mean transvalvular gradient. This study provides a reduction of tricuspid regurgitation after the edge-to-edge technique in the specific experimental setup. Whether this reduction is sufficient to treat tricuspid regurgitation successfully in clinical practice remains to be established. Transcatheter approaches need to be evaluated further, probably with regard to concomitant annuloplasty

Full Text Available Perinatal mortality remains high among fetuses diagnosed with Ebstein's anomaly of the tricuspid valve. The subgroup of patients with pulmonary valve regurgitation is at particularly high risk. In the setting of pulmonary valve regurgitation, early constriction of the ductus arteriosus may be a novel perinatal management strategy to reduce systemic steal resulting from circular shunt physiology. We report the use of chronic antepartum maternal oxygen therapy for constriction of the fetal ductus arteriosus and modulation of fetal pulmonary vascular resistance in a late presentation of Ebstein's anomaly with severe tricuspid valve regurgitation, reversal of flow in the ductus arteriosus, and continuous pulmonary valve regurgitation.

The transatrial repair of the ventricular septal defect (VSD) requires an adequate exposure of its rim. We retrospectively evaluated the impact of adopting the tricuspid valve incision (TVI) technique, either with detachment or radial incision, on the postoperative outcome of children undergoing surgical VSD repair. From January 2008 to September 2017 we retrospectively enrolled 141 patients, divided into two groups: 97 patients were subjected to TVI (68.8%) and 44 patients (31.2%) were not subjected to TVI. All patients received an echocardiogram upon discharge from the hospital and after 1 month, 3 months, 6 months and a year from the treatment. No perioperative or late deaths resulted in our dataset. TVI was associated with a slightly longer cardio-pulmonary bypass and cross-clamp time but there were no differences in the surgical outcome between the two groups. Moreover, no differences occurred concerning residual VSD, atrioventricular block or tricuspid regurgitation at discharge. Echocardiograms at follow-up were available for 134 patients (95%) with a median of 5.3 years (range 0.5-9.3) and the degree of tricuspid regurgitation did not differ between groups. No patient required reoperation for tricuspid regurgitation or residual interventricular shunt. Finally, no difference was found even when comparing the two TVI subgroups. TVI should be used whenever intraoperative exposure of VSD is compromised in order to avoid a residual shunt and atrioventricular block. Here we show that this procedure does not significantly compromise the tricuspid function although a large, multicenter, randomized controlled trial is advised to validate this hypothesis.

Severe tricuspid regurgitation (TR) has long been neglected despite its well known association with mortality. While surgical mortality rates remain high in isolated tricuspid valve surgery, interventional TR repair is rapidly evolving as an alternative to cardiac surgery in selected patients at high surgical risk. Currently, interventional edge-to-edge repair is the most frequently applied technique for TR repair even though the device has not been developed for this particular indication. Due to the inherent differences in tricuspid and mitral valve anatomy and pathology, percutaneous repair of the tricuspid valve is challenging due to a variety of factors including the complexity and variability of tricuspid valve anatomy, echocardiographic visibility of the valve leaflets, and device steering to the tricuspid valve. Furthermore, it remains to be clarified which patients are suitable for a percutaneous tricuspid repair and which features predict a successful procedure. On the basis of the available experience, we describe criteria for patient selection including morphological valve features, a standardized process for echocardiographic screening, and a strategy for clip placement. These criteria will help to achieve standardization of valve assessment and the procedural approach, and to further develop interventional tricuspid valve repair using either currently available devices or dedicated tricuspid edge-to-edge repair devices in the future. In summary, this manuscript will provide guidance for patient selection and echocardiographic screening when considering edge-to-edge repair for severe TR.

A case of traumatic tricuspid insufficiency leading to right atrial enlargement and to a patent foramen ovale with right to left shunting is presented. Six similar cases previously reported are reviewed. The time course of clinical deterioration was related to the type of tricuspid valve damage incurred. Papillary muscle rupture led to surgery within a year, whereas less severe chordal damage allowed a more benign course that lasted from 10 to 25 years from the time of injury to the time of surgery. Surgical repair of the incompetent tricuspid valve and closure of the atrial septal defect led to significant improvement. The diagnostic usefulness of radionuclide imaging and echocardiography is demonstrated in this case. A mechanism of right to left interatrial shunting in the presence of normal pulmonary arterial pressures is proposed; this invokes phasic increases in right atrial pressure from tricuspid insufficiency and streaming of blood from the inferior vena cava into the left atrium across a patent foramen ovale in a manner that resembles conditions in the fetal circulation.

Significant late-onset tricuspid regurgitation (TR) is unfortunately common after double valve replacement (DVR); however, its underlying factors remain undefined. We evaluated the effect of aortic patient-prosthesis mismatch (PPM) on late-onset TR and clinical outcomes after DVR. Of the 2392 consecutive patients who underwent aortic valve replacement between January 1990 and May 2014 at our institution, we retrospectively studied 462 patients who underwent DVR (excluding concomitant tricuspid valvular annuloplasty or replacement). Survival and freedom from grade >3 TR were compared between PPM (n=152) and non-PPM (n=310) groups using the Kaplan-Meier method. Although the overall survival rates were similar between the two groups at 5 and 10 years (95%, 91% vs. 96%, 93%, p=0.412), grade >3 TR-free survival was significantly lower in the PPM group (98%, 91% vs. 99%, 95%, p=0.014). Small body-surface area, atrial fibrillation, PPM, and subaortic pannus were risk factors for TR progression. However, aortic prosthesis size and trans-valvular pressure gradient were not significant factors for either TR progression or overall survival. Aortic PPM in DVR, regardless of mitral prosthesis size, was associated with late TR progression, but was not significantly correlated with overall survival. Therefore, we recommend careful echocardiographic follow-up for the early detection of TR progression in patients with aortic PPM in DVR. © Copyright: Yonsei University College of Medicine 2017

Patients with severe aortic regurgitation frequently present with angina pectoris. The exact pathophysiology for angina in aortic regurgitation is not clear. Left ventricular hypertrophy and myocardial blood supply-demand mismatch have been the suggested mechanisms to explain ischemia. However, no conclusive clinical study exists to define the incidence of ischemia in patients with severe aortic regurgitation and normal coronary arteries. We, therefore, investigated the frequency of myocardial ischemia in relation to left ventricular hypertrophy or dilatation in patients with severe aortic regurgitation and normal coronary arteries. We reviewed the medical records of all patients (n=311) with aortic valve replacement due to aortic regurgitation between 2007 and 2010. We selected subjects with normal coronary arteries (n=182) for the study purpose, and we identified 35 patients who underwent myocardial perfusion scintigraphy prior to the coronary angiography (19 female and 16 male subjects; age 45.0±8.9 years). Left ventricular hypertrophy and dilatation were detected in 9 (26%) and 5 (14%) patients, respectively. Myocardial perfusion scintigraphy showed evidence of ischemia in 10 (29%) patients with normal coronary arteries. The presence of ischemia did not relate to the presence of left ventricular hypertrophy and/or dilatation. As a potential mechanism, aortic regurgitation causes backflow of blood from the aorta into the left ventricle, hence disturbs coronary flow dynamics. In conclusion, myocardial ischemia is common (nearly one-third) among patients with severe aortic regurgitation even in the absence of coronary obstruction, left ventricular hypertrophy and/or dilatation.

Valve sparing reimplantation can improve the durability of bicuspid aortic valve repair compared with subcommissural annuloplasty, especially in patients with a large basal ring. This study analyses the effect of basal ring size and annuloplasty on valve repair in the setting of a tricuspid aortic valve. From 1995 to 2013, 382 patients underwent elective tricuspid aortic valve repair. We included only those undergoing subcommissural annuloplasty, valve sparing reimplantation or no annuloplasty and in whom intraoperative transoesophageal echocardiography images were available for retrospective pre- and post-repair basal ring measurements (n = 323, subcommissural annuloplasty: 146, valve sparing reimplantation: 154, no annuloplasty: 23). In a subgroup of patients with available echocardiographic images, basal ring was retrospectively measured at the latest follow-up or prior to reoperation. subcommissural annuloplasty and valve sparing reimplantation were compared after matching for degree of aortic regurgitation and root size. All three groups differed significantly for most of preoperative characteristics. Hospital mortality was 0.9%. The median follow-up was 4.7 years. At 8 years, overall survival was 80 ± 5%. Freedom from reoperation and freedom from aortic regurgitation >1+ were 92 ± 5% and 71 ± 8%, respectively. In multivariate analysis, predictors of aortic regurgitation >1+ were left ventricular end-diastolic diameter (P = 0.003), cusp repair (P = 0.006), body surface area (P = 0.01) and subcommissural annuloplasty (P = 0.05). In subcommissural annuloplasty, freedom from aortic regurgitation >1+ was lower for patients with basal ring ≥28 mm compared with patients with basal ring 1+ was independent of basal ring size (P = 0.38). In matched comparison between subcommissural annuloplasty and valve sparing reimplantation, freedom from aortic regurgitation >1+ was not significantly different (P = 0.06), but in patients with basal ring ≥28 mm, valve sparing

Color Doppler flow mapping of stenotic and regurgitant natural heart valves

Color Doppler echocardiography has found widest application in reliable detection and assessment of severity of both atrio-ventricular and semi-lunar valve incompetence. The authors believe both the sensitivity and specificity of color Doppler for the detection of mitral and aortic regurgitation is very high in patients with adequate acoustic windows. In 82 patients with proven mitral regurgitation studied, the best correlations with angiography were noted when the maximum or average regurgitant jet are obtained by color Doppler from three standard 2-D echo planes (parasternal long and short axis and apical four chamber view) and expressed as a percentage of the left atrial area were considered. The criteria the authors used for assessment of tricuspid and pulmonary valve incompetence are similar to those used for mitral and aortic valve incompetence, but the lack of a good ''gold'' standard has hampered validation. The color Doppler technique also supplements conventional Doppler in the assessment of severity of stenotic lesions by facilitating parallel alignment of the continuous wave Doppler cursor line with the stenotic jet for accurate recording of maximal velocities and pressure gradients. The authors have found this method especially useful in the assessment of aortic stenosis. In conclusion, color Doppler flow mapping combined with conventional echocardiography provides, for the first time, a comprehensive noninvasive assessement of the severity of regurgitant and stenotic lesions

Although closure of an atrial septal defect type secundum often normalizes right heart dimensions and pressures, mild tricuspid insufficiency might persist. This study aimed at (1) identification of determinants explaining the persistence of tricuspid insufficiency after atrial septal defect closure, and (2) evaluation of functional capacity of patients with persistent mild tricuspid insufficiency. Twenty-five consecutive patients (age 42+17 y) were included from the outpatient clinic of congenital heart disease at the University Hospitals of Leuven. All underwent transthoracic echocardiography, semi-supine bicycle stress echocardiography and cardio-pulmonary exercise testing. Six patients (24%) had mild tricuspid insufficiency (2/4) compared to 19 patients (76%) with no or minimal tricuspid insufficiency ( 1/4) as assessed by semi-quantitative colour Doppler echocardiography. Mann-Whitney U and Fisher's exact tests were performed where applicable. Patients with persistent mild tricuspid insufficiency were significantly older than those with no or minimal tricuspid insufficiency (P = 0.042). At rest, no differences in right heart configuration, mean pulmonary artery pressure or right ventricular function were found. At peak exercise, mean pulmonary artery pressure was significantly higher in patients with mild persistent tricuspid insufficiency (P = 0.026). Peak oxygen uptake was significantly lower in patients with mild persistent tricuspid insufficiency (P = 0.019). Mild tricuspid insufficiency after atrial septal defect repair occurs more frequently in older patients and in patients with higher mean pulmonary artery pressure at peak exercise. In patients with mild tricuspid insufficiency, functional capacity was more reduced. Mild tricuspid insufficiency could be a marker of subclinical persistent pressure load on the right ventricle.

A 28-year-old female who had had irradiation on the chest wall at the age of 5 as a remedy for keloid granulation after burn, recently developed congestive heart failure. Severe tricuspid regurgitation was demonstrated by echocardiography with a certain calcification in the cardiac shadow on chest radiogram. Calcified right ventricle and ventricular septum were noticed operatively, which disturbed ventricular motion and also caused tricuspid valve deformity. These calcified myocardium apparently corresponded with the irradiation field. After tricuspid valve replacement, she regained physical activity satisfactorily without congestive heart failure. Because she had no other known causes of cardiac calcification such as hypercalcemia, myocarditis, myocardial infarction or renal diseases, irradiation on the chest wall could be responsible for the severe myocardial calcification.

The long-term outcome of patients with tetralogy of Fallot (TOF) with reconstruction of the right ventricular (RV) outflow tract is often complicated by the sequelae of severe pulmonary regurgitation. Progressive enlargement of the right ventricle, biventricular dysfunction and arrhythmia are apparent in more than 50% of the patients in the fourth decade of life. Pathophysiologic implications, clinical assessment and diagnostic modalities are discussed, whereas CMR imaging seems to be the procedure of choice. Therapeutical options for rereconstruction of the RV outflow tract are mentioned, surgical and interventional procedures are explained in detail. The optimal timing of reoperation for significant pulmonary regurgitation after TOF repair is still a matter of controversy given the limited runtime of the lately implanted prostheses and the risk of further reoperation. Early surgery is recommended in these patients before symptoms develop, or RV function has declined. Today we believe that waiting for the patient to become symptomatic is too late. All in all, pulmonary valve replacement is at least indicated in patients developing symptoms due to severe pulmonary regurgitation, particularly if associated with substantial or progressive RV dilatation, tricuspid regurgitation and/or supraventricular or ventricular arrhythmias.

Full Text Available With the increase in the number of automobile accidents, traumatic tricuspid insufficiency, a rare complication of non-penetrating blunt chest injury, has become an important problem. This kind of injury has been found more frequently during the last decade, partly because of better diagnostic procedures and a better understanding of the pathology. Here, we report a 22-year-old male patient who suffered chest trauma from an automobile accident. Echocardiography demonstrated tricuspid chordae tendinae rupture with remarkable tricuspid regurgitation. We discuss this case in comparison with the previous literature. This case reminds us that physicians in the emergency department should be aware of this potential complication following non-penetrating chest trauma.

The study covers 300 clinically healthy, randomly selected young subjects, aged 17 to 21 years. The incidence and characteristic features of the valvular regurgitations are assayed by means of pulsed and continuous transthoracic Doppler echocardiography. Valvular insufficiency is registered in total of 198 cases (66%). Regurgitation of single valve is observed in 122 cases (61%), regurgitation of two valves - in 70 (36%) and three valves - in six (3%). Right-sided regurgitations (tricuspid, pulmonic and a combination of both) are detected in 156 subjects, and left-sided (mitral and/or aortic) in twenty-six of which only one regurgitation of the aortic valve. There is a definite tendency of the first two to prevail at a ratio 6:1. A constellation of various anatomical and physiological factors are considered as a likely underlying cause. Whenever atrio-ventricular valves are examined (the mitral one in particular), it is necessary that the regurgitation jet involves over 50% of systole in order to avoid hyperdiagnostics and the so-called 'Doppler's disease'. 14 refs., 1 tab., 2 figs.

Comparative analysis of the results of plastic operations performance on a tricuspid valve (TV) in patients, suffering cardiac insufficiency in terminal stage, was conducted. In late postoperative period the indices of intracardial hemodynamics (cardiac output fraction, regurgitation on TV) and clinical features (severity of symptoms, quality of life) after plastic operations, using a support ring, have differed significantly from those after performance of a sutured plasty. The valve function during five years was secured in 91.1% of patients.

Canines with PH may have right heart pathology documented via echocardiographic color Doppler interrogation including tricuspid valve regurgitation, pulmonic valve insufficiency, elevated pulmonary arterial systolic pressure, elevated pulmonary arterial diastolic pressure, and alterations in ejection profiles. Two-dimensional echocardiographic findings may include right ventricular hypertrophy, interventricular septal flattening, paradoxical interventricular septal motion, pulmonary artery dilation, and potentially abnormal left heart dimensions. In veterinary medicine, much confidence is given to the measurement of pulmonary arterial systolic pressure estimated from tricuspid valve regurgitation to grade the severity of PH and monitor its improvement with little emphasis placed on the integration of two-dimensional echocardiographic right and left heart pathology in conjunction with Doppler findings. To the authors’ knowledge, marked improvement and/or resolution of echocardiographic-documented right heart pathology have not been previously reported in the veterinary literature. This case report documents profound echocardiographic improvement of right-sided heart disease in a dog with severe PH.

Mitral and tricuspid valve asymmetric annular dilation represents the most important mechanism which produces insufficiency. Recent computerized in vitro and in vivo three-dimensional models have been developed in order to better understand the competing factors (annular dilation, displacement of papillary muscles, left and right ventricular geometry). The leading cause of mitral and tricuspid competence is a sphincteric action of both annuli, during systole and diastole, the loss of which produces asymmetric dilation and therefore the absence of cusp coaptation. The Cosgrove-Edwards dynamic ring corrects, alone or in combination with other procedures on the valves, this patho-anatomic feature in a physiological way by restoring the normal annular dimensions and the sphincteric movements during the cardiac cycle. Between June 1998 and May 1999, 30 adult patients underwent mitral (n = 20, Group I) or tricuspid valve repair (n = 10, Group II). Regurgitation was due to a degenerative disease in 13 Group I patients and to ischemic (n = 3), congenital (n = 2) or dilated cardiomyopathy (n = 2) in the others. In Group II the leading cause of insufficiency was functional regurgitation in 7 patients and organic in 3. Associated procedures were carried out in 4 Group I patients and in all Group II patients. Regurgitation was evaluated by transesophageal echocardiography before, during and 3 months after operation. The maximal regurgitant area (MRA) and the grade of insufficiency were evaluated using the equation: MRA 2 4 7 10 cm2 = 4+. The operative mortality was 0%. One Group I patient died 3 months after operation due to bronchopneumonia. No patient was reoperated on for plasty failure in both groups during the follow-up. Mitral insufficiency was absent (grade 0) in 17 Group I patients and mild (grade 1+) in 3 at the end of operation. At 3-month postoperative transesophageal echocardiographic control mitral insufficiency was absent in 14 patients, mild (1+) in 4 and

Left ventricular assist device (LVAD) implantation may alter right ventricular shape and function and lead to tricuspid regurgitation. This in turn has been reported to be a determinant of right ventricular (RV) failure after LVAD implantation, but the effect of mechanical left ventricular (LV) unloading on the tricuspid annulus is unknown. The aim of the study was to provide insight into the effect of LVAD support on tricuspid annular geometry and dynamics that may help to optimize LV unloading with the least deleterious effect on the right-sided geometry. In seven open-chest anaesthetized sheep, nine sonomicrometry crystals were implanted on the right ventricle. Additional nine crystals were implanted around the tricuspid annulus, with one crystal at each commissure defining three separate annular regions: anterior, posterior and septal. Left ventricular unloading was achieved by connecting a cannula in the left atrium and the aorta to a continuous-flow pump. The pump was used for 15 min at a full flow of 3.8 ± 0.3 l/min. Epicardial echocardiography was used to assess the degree of tricuspid insufficiency. Haemodynamic, echocardiographic and sonomicrometry data were collected before and during full unloading. Tricuspid annular area, and the regional and total perimeter were calculated from crystal coordinates, while 3D annular geometry was expressed as the orthogonal distance of each annular crystal to the least squares plane of all annular crystals. There was no significant tricuspid regurgitation observed either before or during LV unloading. Right ventricular free wall to septum diameter increased significantly at end-diastole during unloading from 23.6 ± 5.8 to 26.3 ± 6.5 mm (P = 0.009), but the right ventricular volume, tricuspid annular area and total perimeter did not change from baseline. However, the septal part of the annulus significantly decreased its maximal length (38.6 ± 8.1 to 37.9 ± 8.2 mm, P = 0.03). Annular contraction was not altered. The

Full Text Available The objective of this study was to determine the demographic, clinical and survival characteristics and to identify risk factors for mortality due to tricuspid valve dysplasia in UK dogs. Records of client-owned dogs diagnosed with tricuspid valve dysplasia at a referral centre were retrospectively reviewed. Only dogs diagnosed with tricuspid valve dysplasia based on the presence of a right-sided heart murmur identified prior to one year of age, and confirmed with Doppler echocardiography, were included. Dogs with concomitant cardiac diseases, pulmonary hypertension and/or trivial tricuspid regurgitation were excluded. Analysed data included signalment, reason for presentation, clinical signs, electrocardiographic and echocardiographic features, survival status and cause of death. Survival times and risk factors for mortality were evaluated using Kaplan-Meier curves and Cox regression. Eighteen dogs met inclusion criteria. Border collies were over-represented (p= 0.014. Dogs were most frequently referred for investigation of heart murmur. The most common arrhythmia was atrial fibrillation (n=3. Median survival time from diagnosis of tricuspid valve dysplasia was 2775 days (range 1-3696 days; 95% CI 1542.41-4007.59 and from onset of right-sided congestive heart failure was 181 days (range 1-2130 days; 95% CI 0-455.59. Syncope was the sole risk factor for cardiac death. In this population of UK dogs, tricuspid valve dysplasia was uncommon but, when severe, frequently led to right-sided congestive heart failure. Prognosis was favourable for mild and moderate tricuspid dysplasia. Survival time was reduced with right-sided congestive heart failure but varied widely. Risk of cardiac death was significantly increased if syncope had occurred.

The potential for cardiac implantable electronic device leads to interfere with tricuspid valve (TV) function has gained increasing recognition as having hemodynamic and clinical consequences associated with incremental morbidity and death. The diagnosis and treatment of lead-related (as distinct from functional) tricuspid regurgitation pose unique challenges. Because of pitfalls in routine diagnostic imaging, a high level of clinical suspicion must be maintained to avoid overlooking the possibility that worsening heart failure is a consequence of mechanical interference with TV leaflet mobility or coaptation and is amenable to lead extraction or valve repair or replacement. The future of cardiac implantable electronic devices includes pacing and perhaps defibrillation without a lead traversing the TV. Copyright © 2017 American College of Cardiology Foundation.

2008-04-01

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.

Full Text Available Aim. To evaluate in-hospital and long-term results of surgical treatment of patients with infective endocarditis of the tricuspid valve, to compare the effectiveness of valve repair and valve replacement techniques, and to identify risk factors of mortality and reoperations. Materials and methods. 31 surgical patients with tricuspid valve infective endocarditis were evaluated. Patients were divided into 2 groups. In Group 1 (n = 14 repairs of the tricuspid valve were performed, in Group 2 (n = 17 patients had undergone tricuspid valve replacements. Epidemiological, clinical, microbiological and echocardiographic data were studied. Methods of comparative analysis, the Kaplan–Meier method, and Cox risk models were applied. Results. The most common complication of in-hospital stay was atrioventricular block (17.7% of cases in Group 2. In Group 1, this type of complication was not found. Hospital mortality was 7.14% in Group 1, and 0% in Group 2. Long-term results have shown the significant reduction of heart failure in general cohort and in both groups. In Group 1 the severity of heart failure in the long term was less than in Group 2. No significant differences in the severity of tricuspid regurgitation were found between the groups. In 7-year follow up no cases of death were registered in Group 1. Cumulative survival rate in Group 2 within 60 months was 67.3 ± 16.2%. No reoperations were performed in patients from Group 1. In Group 2, the freedom from reoperation within 60 months was 70.9 ± 15.3%. Combined intervention was found as predictor of postoperative mortality. Prosthetic valve endocarditis was identified as risk factor for reoperation. Conclusion. Valve repair and valve replacement techniques of surgical treatment of tricuspid valve endocarditis can provide satisfactory hospital and long-term results. Tricuspid valve repair techniques allowed reducing the incidence of postoperative atrioventricular block. In the long-term, patients

To quantify mitral regurgitation (MR) with CMR, the regurgitant volume can be calculated as the difference between the left ventricular (LV) stroke volume (SV) measured with the Simpson's method and the reference SV, i.e. the right ventricular SV (RVSV) in patients without tricuspid regurgitation. However, for patients with prominent mitral valve prolapse (MVP), the Simpson's method may underestimate the LV end-systolic volume (LVESV) as it only considers the volume located between the apex and the mitral annulus, and neglects the ventricular volume that is displaced into the left atrium but contained within the prolapsed mitral leaflets at end systole. This may lead to an underestimation of LVESV, and resulting an over-estimation of LVSV, and an over-estimation of mitral regurgitation. The aim of the present study was to assess the impact of prominent MVP on MR quantification by CMR. In patients with MVP (and no more than trace tricuspid regurgitation) MR was quantified by calculating the regurgitant volume as the difference between LVSV and RVSV. LVSV uncorr was calculated conventionally as LV end-diastolic (LVEDV) minus LVESV. A corrected LVESV corr was calculated as the LVESV plus the prolapsed volume, i.e. the volume between the mitral annulus and the prolapsing mitral leaflets. The 2 methods were compared with respect to the MR grading. MR grades were defined as absent or trace, mild (5-29% regurgitant fraction (RF)), moderate (30-49% RF), or severe (≥50% RF). In 35 patients (44.0 ± 23.0y, 14 males, 20 patients with MR) the prolapsed volume was 16.5 ± 8.7 ml. The 2 methods were concordant in only 12 (34%) patients, as the uncorrected method indicated a 1-grade higher MR severity in 23 (66%) patients. For the uncorrected/corrected method, the distribution of the MR grades as absent-trace (0 vs 11, respectively), mild (20 vs 18, respectively), moderate (11 vs 5, respectively), and severe (4 vs 1, respectively) was significantly different (p�

This retrospective study attempted to establish the prevalence of multiple-valve involvement in Marfan syndrome and to compare echocardiographic with histopathologic findings in Marfan patients undergoing valvular or aortic surgery. We reviewed echocardiograms of 73 Marfan patients who underwent cardiovascular surgery from January 2004 through October 2009. Tissue histology was available for comparison in 29 patients. Among the 73 patients, 66 underwent aortic valve replacement or the Bentall procedure. Histologic findings were available in 29 patients, all of whom had myxomatous degeneration. Of 63 patients with moderate or severe aortic regurgitation as determined by echocardiography, 4 had thickened aortic valves. The echocardiographic findings in 18 patients with mitral involvement included mitral prolapse in 15. Of 11 patients with moderate or severe mitral regurgitation as determined by echocardiography, 4 underwent mitral valve repair and 7 mitral valve replacement. Histologic findings among mitral valve replacement patients showed thickened valve tissue and myxomatous degeneration. Tricuspid involvement was seen echocardiographically in 8 patients, all of whom had tricuspid prolapse. Two patients had severe tricuspid regurgitation, and both underwent repair. Both mitral and tricuspid involvement were seen echocardiographically in 7 patients. Among the 73 patients undergoing cardiac surgery for Marfan syndrome, 66 had moderate or severe aortic regurgitation, although their valves manifested few histologic changes. Eighteen patients had mitral involvement (moderate or severe mitral regurgitation, prolapse, or both), and 8 had tricuspid involvement. Mitral valves were most frequently found to have histologic changes, but the tricuspid valve was invariably involved.

To determine the outcome, independent predictors of cardiac death, and the Doppler-derived pressure gradient cut-off for predicting cardiac death in dogs with pulmonic stenosis, with or without tricuspid regurgitation, that do not undergo balloon valvuloplasty or valve surgery. Review of medical records of two UK referral centres between July 1997 and October 2008 for all cases of pulmonic stenosis that had no balloon valvuloplasty or valve surgery. Inclusion criteria included a diagnosis of pulmonic stenosis; spectral Doppler pulmonic velocity greater than 1·6 m/s; characteristic valve leaflet morphological abnormalities. Exclusion criteria included concurrent significant cardiac defects, including tricuspid dysplasia. Dogs with tricuspid regurgitation were included. Dogs were classified according to Doppler-derived pressure gradients into mild, moderate or severe pulmonic stenosis categories. Presence of tricuspid regurgitation and severe stenosis were independent predictors of cardiac death. A pulmonic pressure gradient of more than 60 mmHg was associated with 86% sensitivity, and 71% specificity of predicting cardiac death. There is an increased probability of cardiac death in those cases which have a pulmonary pressure gradient greater than 60 mmHg and tricuspid regurgitation, though the effect of severity of tricuspid regurgitation on outcome was not measurable because of small sample sizes. These animals might benefit from intervention. © 2011 British Small Animal Veterinary Association.

Left ventricular assist device (LVAD) implantation is a well-established therapy to support patients with end-stage heart failure. However, the operative procedure is associated with severe trauma. Third generation LVADs like the HeartWare assist device (HeartWare, Inc., Framingham, MA, USA) are characterized by enhanced technology despite smaller size. These devices offer new minimally invasive surgical options. Tricuspid regurgitation requiring valve repair is frequent in patients with the need for mechanical circulatory support as it is strongly associated with ischemic and nonischemic cardiomyopathy. We report on HeartWare LVAD implantation and simultaneous tricuspid valve reconstruction through minimally invasive access by partial upper sternotomy to the fifth left intercostal space. Four male patients (mean age 51.72 ± 11.95 years) suffering from chronic heart failure due to dilative (three patients) and ischemic (one patient) cardiomyopathy and also exhibiting concomitant tricuspid valve insufficiency due to annular dilation underwent VAD implantation and tricuspid valve annuloplasty. Extracorporeal circulation was established via the ascending aorta, superior vena cava, and right atrium. In all four cases the LVAD implantation and tricuspid valve repair via partial median sternotomy was successful. During the operative procedure, no conversion to full sternotomy was necessary. One patient needed postoperative re-exploration because of pericardial effusion. No postoperative focal neurologic injury was observed. New generation VADs are advantageous because of the possibility of minimally invasive implantation procedure which can therefore minimize surgical trauma. Concomitant tricuspid valve reconstruction can also be performed simultaneously through partial upper sternotomy. Nevertheless, minimally invasive LVAD implantation is a challenging operative technique. © 2016 International Center for Artificial Organs and Transplantation and Wiley Periodicals

Atrioventricular node (AVN) ablation is an effective treatment for symptomatic patients with atrial arrhythmias who are refractory to rhythm and rate control strategies where optimal ventricular rate control is desired. There are limited data on the predictors of failure of AVN ablation. Our objective was to identify the predictors of failure of AVN ablation. This is an observational single-center study of consecutive patients who underwent AVN ablation in a large academic center. Baseline characteristics, procedural variables, and outcomes of AVN ablation were collected. AVN "ablation failure" was defined as resumption of AVN conduction resulting in recurrence of either rapid ventricular response or suboptimal biventricular pacing. A total of 247 patients drug refractory AF who underwent AVN ablation at our center with a mean age of 71 ± 12 years with 46% being males were included. Ablation failure was seen in 11 (4.5%) patients. There were no statistical differences between patients with "ablation failure" versus "ablation success" in any of the baseline clinical variables. Patients with moderate-to-severe tricuspid regurgitation (TR) were much more likely to have ablation failure than those with ablation success (8 [73%] vs 65 [27%]; p = 0.003). All 11 patients with ablation failure had a successful redo procedure, 9 with right and 2 with the left sided approach. On multivariate analysis, presence of moderate-to-severe TR was found to be the only predictor of failure of AVN ablation (odds ratio 9.1, confidence interval 1.99 to 42.22, p = 0.004). In conclusion, moderate-to-severe TR is a strong and independent predictor of failure of AVN ablation. Copyright © 2015 Elsevier Inc. All rights reserved.

A 16-year-old adolescent male sustained combined injuries to the tricuspid valve and liver. This injury is exceptional due to the mechanism and the circumstances in which it took place: a flying pumpkin thrown from a sport utility vehicle. An echocardiogram demonstrated a flail chordal apparatus associated with the posterior leaflet of the tricuspid valve, creating substrate for severe tricuspid regurgitation with preserved right heart function. He was treated with non-operative management for the liver injury; he remained hemodynamically stable and was discharged home. He underwent successful repair of the tricuspid valve 17 days following the initial injury necessitating systemic anticoagulation and was discharged home two days later. The patient recovered fully without residual valvular pathology or hepatic sequelae. Copyright © 2013 Elsevier Inc. All rights reserved.

We report a critically ill premature infant with severe mitral valve regurgitation associated with pulmonary hypertension and a severely dilated left atrium from a large patent ductus arteriosus. The mitral valve regurgitation improved significantly with normalisation of left atrial size 4 weeks after percutaneous closure of the patent ductus arteriosus. This case highlights the potential reversibility of severe mitral valve regurgitation with treatment of an underlying cardiac shunt.

Tricuspid regurgitation may be a precursor for heart failure, reduced functional capacity, and poor survival. A human compatible experimental model is required to understand the pathophysiology of the tricuspid valve disease as a basis for validating novel tricuspid valve interventions before clinical use. The study aim was to evaluate and compare the tricuspid valve anatomy of porcine and human hearts. The anatomy of the tricuspid valve and the surrounding structures that affect the valve during a cardiac cycle were examined in detail in 100 fresh and 19 formalin-fixed porcine hearts obtained from Danish Landrace pigs (body weight 80 kg). All valvular dimensions were compared with human data acquired from literature sources. No difference was seen in the tricuspid annulus circumference between porcine and human hearts (13.0 ± 1.2 cm versus 13.5 ± 1.5 cm; p = NS), or in valve area (5.7 ± 1.6 cm2 versus 5.6 ± 1.0 cm2; p = NS). The majority of chordae types exhibited a larger chordal length and thickness in human hearts compared to porcine hearts. In both species, the anterior papillary muscle (PM) was larger than other PMs in the right ventricle, but muscle length varied greatly (range: 5.2-40.3 mm) and was significantly different in pigs and in humans (12.2 ± 3.2 mm versus 19.2 mm; p human hearts.

This study assesses the results of the 'clover technique' (suturing together the middle point of the free edges of the tricuspid leaflets) for the treatment of tricuspid regurgitation (TR) due to severe prolapse or tethering. From 2001, 66 patients with severe TR due to prolapsing or tethered leaflets underwent 'clover repair'. Annuloplasty was associated in 64 patients (97%). The aetiology of TR was degenerative in 52 cases (79%), post-traumatic in eight (12%) and secondary to dilated cardiomyopathy (DCM) in six (9%). The main mechanism of TR was prolapse/flail of one leaflet in 15 patients (23%), of two leaflets in 31 (47%) and of all three leaflets in 14 (21%). The remaining six patients (9%) presented with severe leaflets' tethering. Four deaths (6%) occurred during hospitalisation and one patient died 3.6 years after surgery. Survival was 91 + or - 4.1% at 5 years. Follow-up of the 62 hospital survivors was 100% complete (mean length 3.5 + or - 1.6 years, range 13 months-7.1 years). At the last echocardiogram, no or mild TR was detected in 55 (88.7%) patients, moderate (2+/4+) in six (9.6%) and severe (4+/4+) in one patient (1.6%). Mean tricuspid valve area and gradient were 4.3 + or - 0.6 cm(2) and 2.8 + or -1.4 mmHg. In six patients, stress echocardiography was performed and no signs of tricuspid stenosis were detected. At the multivariable analysis, the degree of TR at hospital discharge was identified as the only predictor of TR > or = 2+ at follow-up. Midterm clinical and echocardiographic results confirm the role of the 'clover technique' in the surgical treatment of TR due to lesions, which are unlikely to be effectively treatable by annuloplasty alone.

Tricuspid annuloplasty procedures have been widely performed in clinics for many years. The Kalangos Biodegradable Tricuspid Ring (Kalangos Biodegradable Tricuspid Ring, Bioring SA, Lonay, Switzerland) is a novel prosthesis for the treatment of tricuspid insufficiency. The aim of this study was to evaluate the clinical and echocardiographic results of this novel prosthesis for functional tricuspid insufficiency. Between October 2005 and May 2006, 15 patients with the diagnosis of moderate or severe functional tricuspid insufficiency were treated by implantation of a Kalangos Biodegradable Tricuspid Ring. All patients were evaluated clinically and by echocardiography preoperatively, and control tests were performed at the end of the 1st and 6th month following surgery. Moderate and severe insufficiency was documented in 11 and 4 patients, respectively, in the preoperative tests. 1 and 6 months after surgery, 4 patients had trace and 1 patient had mild tricuspid insufficiency, while 10 patients had none. At the 1st and 6th month follow-up, systolic pulmonary arterial pressure, right atrial dimension and right ventricular diastolic diameter were found to be significantly lower than the preoperative values ( P tricuspid valve area had decreased significantly at the end of the 1st month; however, no significant difference was found between the 1st and 6th month tests ( P > 0.05). Three-quarters of the annuloplasty ring had degraded at 6 months. No complications related to the prosthesis or the procedure occurred within this period. Kalangos Biodegradable Ring is a promising prosthesis in patients with functional tricuspid insufficiency, with encouraging initial results.

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.

В. М. Назаров

2015-10-01

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.

Full Text Available The aim – to evaluate different methods of surgical treatment of ventricular septal defect (VSD, combined with failure of the tricuspid valve (TC, and to develop optimal algorithm for the treatment of patients with this pathology. Materials and methods. Between 2010 and 2014, 35 patients, average age 80.9±20.5 months, underwent tricuspidal annuloplasty within correction of VSD in Center of Cardiac Surgery of Republic of Moldova. Tricuspidal regurgitation of the II grade was diagnosed valve in 20 (57.0 % cases, III grade – in 8 (23.0 % cases, IV grade – in 7 (20.0 % of cases. Within correction of VSD plastics of tricuspidal valve was performed: in 4 cases (11.0 % of patients plastics by De Vega, in 14 cases (40.0 % of patients – comissuroplastics, in 6 cases (17.0 % – comissuroplastics and suture of cleft, in 1 case (4.0 % plastics by De Vega with comissuroplastics, in 10 cases (29.0 % – comissuroplastics and suture of cleft. Results. After operation the clinic status improved significantly: breathlessness reduced from 91.7 % to 8.3 % cases, tachycardia reduced from 91.7 % to 33.3 % cases and other cardiac failure symptoms – from 10.8 % to 4.2 % cases. The number of patients with NYHA class I heart failure after surgery was 54.2 % compared to its absence before operation, class 2 diminished from 60.0 % to 41.7 % cases, class 3 – from 36.0 % to 4.2 % cases. Conclusions. Anteroseptal comissuroplastics was used in majority of cases. This method is simple, reliable and inexpensive, requires not more than 5–10 min and significantly reduces tricuspidal valve insufficiency.

The classification of clinical severity of Ebstein anomaly still remains a challenge. The aim of this study was to focus on the interaction of the pathologically altered right heart with the anatomically-supposedly-normal left heart and to derive from cardiac magnetic resonance (CMR) a simple imaging measure for the clinical severity of Ebstein anomaly. Twenty-five patients at a mean age of 26±14 years with unrepaired Ebstein anomaly were examined in a prospective study. Disease severity was classified using CMR volumes and functional measurements in comparison with heart failure markers from clinical data, ECG, laboratory and cardiopulmonary exercise testing, and echocardiography. All examinations were completed within 24 hours. A total right/left-volume index was defined from end-diastolic volume measurements in CMR: total right/left-volume index=(RA+aRV+fRV)/(LA+LV). Mean total right/left-volume index was 2.6±1.7 (normal values: 1.1±0.1). This new total right/left-volume index correlated with almost all clinically used biomarkers of heart failure: brain natriuretic peptide (r=0.691; P=0.0003), QRS (r=0.432; P=0.039), peak oxygen consumption/kg (r=-0.479; P=0.024), ventilatory response to carbon dioxide production at anaerobic threshold (r=0.426; P=0.048), the severity of tricuspid regurgitation (r=0.692; P=0.009), tricuspid valve offset (r=0.583; P=0.004), and tricuspid annular plane systolic excursion (r=0.554; P=0.006). Previously described severity indices ([RA+aRV]/[fRV+LA+LV]) and fRV/LV end-diastolic volume corresponded only to some parameters. In patients with Ebstein anomaly, the easily acquired index of right-sided to left-sided heart volumes from CMR correlated well with established heart failure markers. Our data suggest that the total right/left-volume index should be used as a new and simplified CMR measure, allowing more accurate assessment of disease severity than previously described scoring systems. © 2014 American Heart Association, Inc.

There are limited reports of severe tricuspid valve stenosis in dogs and limited data regarding treatment and outcome. To evaluate clinical signs, echocardiographic features, and outcome of balloon valvuloplasty (BV) in dogs with severe tricuspid valve stenosis (TVS) in which BV was attempted. Five client-owned dogs with severe TVS. Records were retrospectively reviewed and data collected regarding signalment, clinical signs, diagnostic findings, procedures, and outcome. All dogs were Labrador Retrievers. Presenting complaints included episodic weakness/syncope (4/5), abdominal distension (4/5), lethargy (2/5), and exercise intolerance (2/5). The median and range of measurements before BV were as follows: TV mean velocity 1.5 m/s (range 1.4-1.7 m/s); velocity-time integral (VTI) 79.8 cm (42.4-99.1 cm); and TV maximum velocity 2.9 m/s (2.3-3.2 m/s). Measurements (available for 3 of 5 dogs) after BV were as follows: TV mean velocity 1.15 m/s (0.9-1.4 m/s); VTI 44.95 cm (41.4-54.8 cm); and TV maximum velocity 1.15 m/s (1.9-2.3 m/s). The procedure was attempted in all dogs and completed in 4/5 dogs. The largest balloon diameter ranged from 15 mm to 25 mm, and length ranged from 4 cm to 5 cm. Right atrial pressure decreased in 4/5 dogs. All but 1 dog had clinical improvement after BV, but recurrence of clinical signs occurred (2/5). Tricuspid regurgitation worsened in 1 dog culminating in right heart failure and euthanasia. BV can be an effective treatment; however, clinical signs can recur. Right heart failure due to worsened TR is a potential complication in dogs with pre-existing moderate-to-severe TR. Copyright © 2017 The Authors.

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.

A prosthetic system to repair secondary tricuspid valve regurgitation was developed. The conceptual engineering of the current device is based on 3D segmental remodelling of the tricuspid valve annulus in lieu of reductive annuloplasty. This study was designed to investigate the operational safety of the current prosthetic system with regard to the anatomical integrity of the right coronary artery (RCA) in fresh cadaveric human hearts. During the study period, from January to April 2016, the current prosthetic system was implanted on the tricuspid valve annulus in fresh cadaveric human hearts that met the study's inclusion criteria. The prepared specimens were investigated via selective coronary angiography of the RCA in the catheterization laboratory. The RCA angiographic anatomies were categorized as normal, distorted, kinked or occluded. Sixteen specimens underwent implantation of the current prosthetic system. The mean age of the cadaveric human hearts was 43.24 ± 15.79 years, with vehicle accident being the primary cause of death (59%). A dominant RCA was noticed in 62.5% of the specimens. None of the specimens displayed any injury, distortion, kinking or occlusion in the RCA due to the implantation of the prostheses. In light of the results of the present study, undertaken on fresh cadaveric human heart specimens, the current segmental prosthetic system for 3D remodelling of the tricuspid valve annulus seems to be safe vis-à-vis the anatomical integrity of the RCA. Further in vivo studies are needed to investigate the functional features of the current prosthetic system with a view to addressing the complex pathophysiology of secondary tricuspid valve regurgitation. © The Author 2017.

Annuloplasty for functional mitral or tricuspid regurgitation has been made for surgical restoration of valvular diseases. However, these major techniques may sometimes be ineffective because of chamber dilation and valve tethering. We have been developing a sophisticated intelligent artificial papillary muscle (PM) by using an anisotropic shape memory alloy fiber for an alternative surgical reconstruction of the continuity of the mitral structural apparatus and the left ventricular myocardium. This study exhibited the mitral regurgitation with regard to the reduction in the PM tension quantitatively with an originally developed ventricular simulator using isolated goat hearts for the sophisticated artificial PM. Aortic and mitral valves with left ventricular free wall portions of isolated goat hearts (n=9) were secured on the elastic plastic membrane and statically pressurized, which led to valvular leaflet-papillary muscle positional change and central mitral regurgitation. PMs were connected to the load cell, and the relationship between the tension of regurgitation and PM tension were measured. Then we connected the left ventricular specimen model to our hydraulic ventricular simulator and achieved hemodynamic simulation with the controlled tension of PMs.

2015-02-01

Full Text Available Background: Mitral regurgitation is one of the leading causes of cardiovascular morbidity in pediatric patients with Marfan syndrome. The purpose of this study was to contribute to determining the appropriate surgical strategy for these patients. Methods: From January 1992 to May 2013, six patients with Marfan syndrome underwent surgery for mitral regurgitation in infancy or early childhood. Results: The median age at the time of surgery was 47 months (range, 3 to 140 months and the median follow-up period was 3.6 years (range, 1.3 to 15.5 years. Mitral valve repair was performed in two patients and four patients underwent mitral valve replacement with a mechanical prosthesis. There was one reoperation requiring valve replacement for aggravated mitral regurgitation two months after repair. The four patients who underwent mitral valve replacement did not experience any complications related to the prosthetic valve. One late death occurred due to progressive emphysema and tricuspid regurgitation. Conclusion: Although repair can be an option for some patients, it may not be durable in infantile-onset Marfan syndrome patients who require surgical management during infancy or childhood. Mitral valve replacement is a feasible treatment option for these patients.

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

Background Long-term follow-up data concerning isolated tricuspid valve pathology after replacement or reconstruction is limited. Current American Heart Association guidelines equally recommend repair and replacement when surgical intervention is indicated. Our aim was to investigate and compare operative mortality and long-term survival in patients undergoing isolated tricuspid valve repair surgery versus replacement. Material/Methods Between 1995 and 2011, 109 consecutive patients underwent surgical correction of tricuspid valve pathology at our institution for varying structural pathologies. A total of 41 (37.6%) patients underwent tricuspid annuloplasty/repair (TAP) with or without ring implantation, while 68 (62.3%) patients received tricuspid valve replacement (TVR) of whom 36 (53%) were mechanical and 32 (47%) were biological prostheses. Results Early survival at 30 days after surgery was 97.6% in the TAP group and 91.1% in the TVR group. After 6 months, 89.1% in the TAP group and 87.8% in the TVR group were alive. In terms of long-term survival, there was no further mortality observed after one year post surgery in both groups (Log Rank p=0.919, Breslow p=0.834, Tarone-Ware p=0.880) in the Kaplan-Meier Survival analysis. The 1-, 5-, and 8-year survival rates were 85.8% for TAP and 87.8% for TVR group. Conclusions Surgical repair of the tricuspid valve does not show survival benefit when compared to replacement. Hence valve replacement should be considered generously in patients with reasonable suspicion that regurgitation after repair will reoccur. PMID:28236633

The study objective was to investigate whether, in patients undergoing surgery for degenerative mitral valve disease, associated right ventricular remodeling and dysfunction are stronger determinants of preoperative organ dysfunction and prognosis than functional tricuspid regurgitation. From January 2001 to January 2011, 4197 patients underwent primary mitral valve surgery for degenerative valve disease at Cleveland Clinic. Using a quasi-experimental enriched study design, 781 patients were randomly selected within each grade of functional tricuspid regurgitation. Renal function was assessed by glomerular filtration rate and blood urea nitrogen, and hepatic function was assessed by Model for End-stage Liver Disease (MELD) score. Preoperative and postoperative right ventricular morphology and function were measured de novo on stored echocardiographic images. To assess survival, 3471 patient-years of follow-up data were available for analysis. Several preoperative right ventricular variables, but not functional tricuspid regurgitation grade (P>.05), were associated with preoperative renal and hepatic dysfunction, but neither was associated with early mortality (.2), was among the risk factors for later mortality. Postoperative unadjusted right ventricular function, but not functional tricuspid regurgitation grade (P≥.2), was associated with both early (P=.04) and later (P=.01) mortality, but in multivariable analysis appeared to be a surrogate for worse preoperative condition. Together with patient comorbidities and operative factors, right ventricular morphology and function are associated more strongly with preoperative organ dysfunction and prognosis than is functional tricuspid regurgitation severity in patients undergoing surgery for degenerative mitral valve disease. Our previous study showed that tricuspid valve repair remains the most effective treatment to improve right ventricular function. Copyright © 2014 The American Association for Thoracic Surgery

This study compares the medium-term results of De Vega, modified De Vega, and ring annuloplasty techniques for the correction of tricuspid insufficiency and investigates the risk factors for recurrent grades 3 and 4 tricuspid insufficiency after repair. In our clinic, 93 patients with functional tricuspid insufficiency underwent surgical tricuspid repair from May 2007 through October 2010. The study was retrospective, and all the data pertaining to the patients were retrieved from hospital records. Functional capacity, recurrent tricuspid insufficiency, and risk factors aggravating the insufficiency were analyzed for each patient. In the medium term (25.4 ± 10.3 mo), the rates of grades 3 and 4 tricuspid insufficiency in the De Vega, modified De Vega, and ring annuloplasty groups were 31%, 23.1%, and 6.1%, respectively. Logistic regression analysis revealed that chronic obstructive pulmonary disease, left ventricular dysfunction (ejection fraction, tricuspid insufficiency. Medium-term survival was 90.6% for the De Vega group, 96.3% for the modified De Vega group, and 97.1% for the ring annuloplasty group. Ring annuloplasty provided the best relief from recurrent tricuspid insufficiency when compared with DeVega annuloplasty. Modified De Vega annuloplasty might be a suitable alternative to ring annuloplasty when rings are not available. PMID:23466680

A 19-year-old male was admitted to the emergency room of our hospital after a motor vehicle accident. During his first physical examination, a holosystolic murmur was heard at the fourth left parasternal border. Transthoracic echocardiography showed severe tricuspid insufficiency, but the cause of tricuspid insufficiency was unclear. Therefore, three-dimensional echocardiography was performed and demonstrated flail anterior, posterior and septal leaflets of the tricuspid valve. The diagnosis was tricuspid insufficiency due to papillary muscle rupture secondary to chest blunt trauma. Surgical repair of the tricuspid valve was performed in this patient. After surgery, the signs and symptoms of right ventricular heart failure were relieved. In this case, three-dimensional echocardiography was very useful for the evaluation of spatial destruction of the tricuspid valve and papillary muscle. 2009 Japanese College of Cardiology.

The value of right ventriculography in the diagnosis of tricuspid insufficiency (TI) is often questioned because of 1) the high incidence of premature ventricular contractions (PVCs) during injections and 2) interference of the catheter in the valve closure mechanism. In 168 patients a commercially available, not preshaped, balloon-tipped catheter was used for right ventriculography. To avoid the induction of PVCs, the catheter tip was placed in the middle third of the diafragmatic wall of the right ventricle, and the balloon was inflated, becoming trapped by the trabeculae. In this position the catheter's side holes should be located in the inflow chamber. To ensure this correct position, and therefore lack of ectopic beats during angiography, a saline test injection was performed previously in every case. With this technique the incidence of PVCs during ventriculography was only 7.7%. In all but one case, such beats were isolated. The 168 patients were divided into three groups according to their likelihood of experiencing tricuspid interference by the catheter: group 1 included 41 patients with a normal heart or with coronary artery disease. No one from this group had TI. Of group II, 28 patients with right ventricular pressure or volume overload or cardiomyopathy, only 2 had TI, both with a previous clinical diagnosis of regurgitation. Group III contained 99 patients with rheumatic heart disease. Thirty-five of them showed angiographic TI, and 24 of these had this diagnosis confirmed either clinically or at surgery. It is felt that this technique of right ventriculography, with its low incidence of PVCs and slight interference with tricuspid closure, is a valid method for the objective study of the tricuspid valve.

Full Text Available Behcet's aortitis is a rare, but one of the most severe complications of Behcet's disease. We report a 24-year-old woman who was noted initially to have aortitis and severe aortic regurgitation caused by Behcet's disease. After receiving aortic valve replacement, aortoplasty and immunosuppressant therapy, her condition became stationary. As far as we are aware, she is the youngest case that has undergone surgery. The early onset of hemodynamic decompensation is considered to be related to delay in diagnosis and lack of steroid treatment.

The Double-Orifice Valve Technique to Treat Tricuspid Valve Incompetence.

Hetzer, Roland; Javier, Mariano; Delmo Walter, Eva Maria

2016-01-01

A straightforward tricuspid valve (TV) repair technique was used to treat either moderate or severe functional (normal valve with dilated annulus) or for primary/organic (Ebstein's anomaly, leaflet retraction/tethering and chordal malposition/tethering, with annular dilatation) TV incompetence, and its long-term outcome assessed. A double-orifice valve technique was employed in 91 patients (mean age 52.6 ± 23.2 years; median age 56 years; range: 0.6-82 years) with severe tricuspid regurgitation. Among the patients, three had post-transplant iatrogenic chordal rupture, five had infective endocarditis, 11 had mitral valve insufficiency, 23 had Ebstein's anomaly, and 47 had isolated severe TV incompetence. The basic principle was to reduce the distance between the coapting leaflets, wherein the most mobile leaflet could coapt to the opposite leaflet, by creating two orifices, ensuring valve competence. The TV repair was performed through a median sternotomy or right anterior thoracotomy in the fifth intercostal space under cardiopulmonary bypass. The degree and extent of creating a double-valve orifice was determined by considering the minimal body surface area (BSA)-related acceptable TV diameter. Repair was accomplished by passing pledgeted mattress sutures from the middle of the true anterior annulus to a spot on the opposite septal annulus, located approximately two-thirds of the length of the septal annulus to avoid injury to the bundle of His. The annular apposition divides the TV into a larger anterior and a smaller posterior orifices, enabling valve closure, on both sides. In adults, the diameter of the anterior valve orifice should be 23-25 mm, and the posterior orifice 15-18 mm; thus, the total valve orifice area is 5-6 cm2. In children, the total valve orifice should be a standard deviation of 1.7 mm for a BSA of 1.0m2. During a mean follow up of 8.7 ± 1.34 years (median 10 years; range: 1.5-25.9 years) there have been no reoperations for TV insufficiency

Transcatheter closure is the usual treatment for patent ductus arteriosus (PDA), but its safety and efficacy have not been reported in adult PDA patients with severe mitral regurgitation. A retrospective study on 27 consecutive patients diagnosed with PDA and severe mitral regurgitation and treated using transcatheter closure between September 2010 and September 2012 at the Department of Cardiology of Changhai Hospital in Changhai, China. Left ventricular (LV) diastolic volume and function, pulmonary artery pressure, and instantaneous reverse-flow volume were examined by echocardiography before PDA closure, immediately after closure, and 1 year after closure. After the procedure, the LV diastolic volume (P.05). Pulmonary arterial systolic pressure was unchanged 1 year after closure (from 46.41 ± 19.92 mm Hg to 45.43 ± 13.64 mm Hg; P=.58). All procedures were uneventful and only mild complications occurred (hemolysis in 2 cases, subcutaneous hematoma in 4 cases, and fever in 2 cases). Transcatheter closure can decrease the LV volume and instantaneous reverse-flow volume in adult PDA patients with severe mitral regurgitation. This procedure is effective and has a good safety profile.

Full Text Available Background: We evaluated the early clinical outcomes of tricuspid valve annuloplasty (TAP with the Tri-Ad annuloplasty ring for functional tricuspid regurgitation (TR. Methods: From January 2015 to March 2017, 36 patients underwent TAP with a Tri-Ad ring for functional TR. To evaluate the early clinical outcomes of TAP with the Tri-Ad ring, we conducted a propensity score-matched analysis comparing the Tri-Ad and MC³ tri-cuspid annuloplasty rings (n=34 in each group. The follow-up duration was 11.0±7.07 months. Results: There was 1 case of operative mortality (2.8% and no cases of late mortality. Postoperative complications occurred in 15 patients (41%, including acute kidney injury in 6 patients (16%, bleeding requiring reoperation in 4 patients (11%, and low cardiac output syndrome in 4 patients (11%. There were no ring-related complications, such as atrioventricular block or ring dehiscence. The TR grade decreased significantly (from 2.03±1.06 to 1.18±0.92, p<0.01, as did the systolic pulmonary artery pressure (from 43.53±13.84 to 38.00±9.72 mm Hg, p=0.03. There were no cases of severe residual TR, but moderate TR was observed in 3 patients, all of whom had severe TR preoperatively. Severe preoperative TR was also associated with moderate in the univariate analysis (p<0.01. In the propensity score-matched analysis comparing the Tri-Ad and MC³ rings, there was no significant difference in early clinical outcomes. Conclusion: TAP with the Tri-Ad ring corrected functional TR effectively and provided good early clinical and echocardiographic results without ring-related complications. However, severe preoperative TR was associated with moderate or severe residual TR in the immediate postoperative period. A follow-up study is necessary to confirm the stability of this procedure.

Highlights: ► Oxidative stress has been implicated in the pathomechanism of calcific aortic valve stenosis. ► We assessed the transcript levels for PARP-1 (poly(ADP-ribose) polymerase), acts as a DNA damage nick sensor in stenotic valves. ► Early stage of diseased tricuspid valves exhibited higher mRNA levels for PARP-1 compared to bicuspid valves. ► The mRNA levels for PARP-1 inversely correlated with the clinical stenosis severity in tricuspid valves. ► Our data demonstrated that DNA damage pathways might be associated with stenosis severity only in tricuspid valves. -- Abstract: Oxidative stress may contribute to the hemodynamic progression of aortic valve stenosis, and is associated with activation of the nuclear enzyme poly(ADP-ribose) polymerase (PARP) 1. The aim of the present study was to assess the transcriptional profile and the topological distribution of PARP-1 in human aortic valves, and its relation to the stenosis severity. Human stenotic aortic valves were obtained from 46 patients undergoing aortic valve replacement surgery and used for mRNA extraction followed by quantitative real-time PCR to correlate the PARP-1 expression levels with the non invasive hemodynamic parameters quantifying the stenosis severity. Primary isolated valvular interstitial cells (VICs) were used to explore the effects of cytokines and leukotriene C 4 (LTC 4 ) on valvular PARP-1 expression. The thickened areas of stenotic valves with tricuspid morphology expressed significantly higher levels of PARP-1 mRNA compared with the corresponding part of bicuspid valves (0.501 vs 0.243, P = 0.01). Furthermore, the quantitative gene expression levels of PARP-1 were inversely correlated with the aortic valve area (AVA) (r = −0.46, P = 0.0469) and AVA indexed for body surface area (BSA) (r = −0.498; P = 0.0298) only in tricuspid aortic valves. LTC 4 (1 nM) significantly elevated the mRNA levels of PARP-1 by 2.38-fold in VICs. Taken together, these data suggest that

Idiopathic mitral valve prolapse with tricuspid, aortic and pulmonary valve involvement: An autopsy case report

Directory of Open Access Journals (Sweden)

Heena M Desai

2015-01-01

Full Text Available Mitral valve prolapse (MVP is usually asymptomatic, but can be associated with complications such as infective endocarditis, mitral regurgitation, thromboembolism and sudden cardiac death. It has been very rarely reported to occur in association with other valvular involvement. A 55-year-old male patient was brought dead and at autopsy the mitral valve orifice was stenotic and the leaflets were enlarged, myxoid and bulging suggestive of MVP and chordae tendinae were thickened, stretched and elongated. Similar changes were seen in the tricuspid valve. The pulmonary and aortic valves also showed myxomatous degeneration of their cusps. Myxomatous degeneration is the most common cause of MVP and it can be associated with involvement of the other valves. Concomitant involvement of the aortic valve has been reported, however it is very rare and simultaneous involvement of the pulmonary valve has not been reported in the literature so far. We report a case of MVP associated with myxomatous degeneration of the tricuspid, pulmonary and aortic valves.

Acute aortic regurgitation (AR) is an important finding associated with a wide variety of disease processes. Its timely diagnosis is of utmost importance. Delay in diagnosis could prove fatal. We describe a case of acute severe AR that was timely diagnosed using real time three-dimensional (3D) transesophageal echocardiogram (3D TEE). Not only did it diagnose but also the images obtained by 3D TEE clearly matched with the pathologic specimen. Using this sophisticated imaging modality that is mostly available at the tertiary centers helped in the timely diagnosis, which lead to the optimal management saving his life. Echocardiography and especially 3D TEE can diagnose AR very accurately. Surgical intervention is the definitive treatment but medical therapy is utilized to stabilize the patient initially.

2007-02-01

Full Text Available Abstract Background Apical ballooning syndrome (or Takotsubo cardiomyopathy is a syndrome of transient left ventricular apical ballooning. Although first described in Japanese patients, it is now well reported in the Caucasian population. The syndrome mimicks an acute myocardial infarction but is characterised by the absence of obstructive coronary disease. We describe a serious and poorly understood complication of Takotsubo cardiomyopathy. Case Presentation We present the case of a 65 year-old lady referred to us from a rural hospital where she was treated with thrombolytic therapy for a presumed acute anterior myocardial infarction. Four hours after thrombolysis she developed acute pulmonary oedema and a new systolic murmur. It was presumed she had acute mitral regurgitation secondary to a ruptured papillary muscle, ischaemic dysfunction or an acute ventricular septal defect. Echocardiogram revealed severe mitral regurgitation, left ventricular apical ballooning, and systolic anterior motion of the mitral valve with significant left ventricular outflow tract gradient (60–70 mmHg. Coronary angiography revealed no obstructive coronary lesions. She had an intra-aortic balloon pump inserted with no improvement in her parlous haemodynamic state. We elected to replace her mitral valve to correct the outflow tract gradient and mitral regurgitation. Intra-operatively the mitral valve was mildly myxomatous but there were no structural abnormalities. She had a mechanical mitral valve replacement with a 29 mm St Jude valve. Post-operatively, her left ventricular outflow obstruction resolved and ventricular function returned to normal over the subsequent 10 days. She recovered well. Conclusion This case represents a serious and poorly understood association of Takotsubo cardiomyopathy with acute pulmonary oedema, severe mitral regurgitaton and systolic anterior motion of the mitral valve with significant left ventricular outflow tract obstruction.

Full Text Available Abstract Background This study was done to investigate the potential additional role of virtual reality, using three-dimensional (3D echocardiographic holograms, in the postoperative assessment of tricuspid valve function after surgical closure of ventricular septal defect (VSD. Methods 12 data sets from intraoperative epicardial echocardiographic studies in 5 operations (patient age at operation 3 weeks to 4 years and bodyweight at operation 3.8 to 17.2 kg after surgical closure of VSD were included in the study. The data sets were analysed as two-dimensional (2D images on the screen of the ultrasound system as well as holograms in an I-space virtual reality (VR system. The 2D images were assessed for tricuspid valve function. In the I-Space, a 6 degrees-of-freedom controller was used to create the necessary projectory positions and cutting planes in the hologram. The holograms were used for additional assessment of tricuspid valve leaflet mobility. Results All data sets could be used for 2D as well as holographic analysis. In all data sets the area of interest could be identified. The 2D analysis showed no tricuspid valve stenosis or regurgitation. Leaflet mobility was considered normal. In the virtual reality of the I-Space, all data sets allowed to assess the tricuspid leaflet level in a single holographic representation. In 3 holograms the septal leaflet showed restricted mobility that was not appreciated in the 2D echocardiogram. In 4 data sets the posterior leaflet and the tricuspid papillary apparatus were not completely included. Conclusion This report shows that dynamic holographic imaging of intraoperative postoperative echocardiographic data regarding tricuspid valve function after VSD closure is feasible. Holographic analysis allows for additional tricuspid valve leaflet mobility analysis. The large size of the probe, in relation to small size of the patient, may preclude a complete data set. At the moment the requirement of an I

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.

=severe. Myocardial performance was evaluated by ventricular ejection fraction and invasive hemodynamic study performed during routine endomyocardial biopsies. RESULTS: Mean clinical follow-up was 14.6±4.3 (6 and 16 months. There was only one death in group II. It was not related to annuloplasty. Mean degree of tricuspid regurgitation in Group I was 0.4±0.6 and in Group II was 1.6±0.8 (p < 0.05. There was a statistically significant difference between both groups in right atrium pressure, which was higher in Group II. CONCLUSIONS: In view of the limitations of the study, the prophylactic tricuspid annuloplasty in heart donor reduced the degree of valvar regurgitation in the medium term after heart transplantation with bicaval anastomosis, in spite of not interfering with the allograft hemodynamic performance in the period under consideration.

The use of laser lead extraction (LLE) to remove pacemaker and implantable cardiac defibrillator leads has become more prevalent in the past decade. Though the procedure is associated with a low rate of complications, LLE still poses some risks to patients. Some reports have suggested an increase in tricuspid insufficiency (TI) associated with LLE. We present a series of patients who underwent both LLE and complete evaluation for TI with echocardiographic techniques. From August 2008 to January 2010, 173 prospective, consecutive patients underwent LLE in a single center. All patients had transesophageal echocardiograms (TEE) during the extraction. Fifty-three patients had tricuspid valve function evaluated a day before the procedure with a transthoracic echocardiogram (TTE), during the procedure with a TEE and 2 days postoperatively with a TTE. All 173 patients experienced no change in tricuspid valve function during the procedure with TEE. Of the 53 patients who underwent a complete TI evaluation, 38 were males (72%) and 15 females (38%), with a mean age of 69.45 ± 14.08. Mean ejection fraction was 35.82 ± 14.72. Three (6%) patients experienced TI after the procedure (two mild and one severe, all with tricuspid valve endocarditis); 16 (30%) patients were found to have TI before LLE that returned to normal valve function during or after the procedure. Thirty-four (64%) patients did not experience any significant change of the tricuspid valve performance after LLE. LLE was not associated with increased TI. ©2013, The Authors.

The first-pass radionuclide technique can be used to evaluate valvular regurgitation. Sixty-three patients were studied with cardiac catheterization and first-pass radionuclide angiography. The degree of regurgitation by cardiac catheterization was evaluated by using a ranking scale of 0-4, where 4 is severe regurgitation. The results were as follows: for nine patients, rank = 0, and percentage of regurgitation (mean +- SD) = 3.6 +- 5; for five patients, rank = 1 and percentage regurgitation = 15.8 +- 3; for 13 patients, rank = 2 and percentage regurgitation = 28.5 +- 14; for 16 patients, rank = 3 and percentage regurgitation = 41.5 +- 10; and for 19 patients, rank = 4 and percentage regurgitation 54.9 +- 13. A correlation coefficient of .90 between cardiac catheterization and the first-pass technique was calculated. The authors conclude that first-pass radionuclide angiography can quantitate valvular regurgitation and accurately differentiate between no, minimal, moderate, and severe valvular regurgitation

Management of aortic regurgitation depends on the assessment for severity. Echocardiography remains as the most widely available tool for evaluation of aortic regurgitation. In this manuscript, we describe a novel parameter, jet length/velocity ratio, for the diagnosis of severe aortic regurgitation. A total of 30 patients with aortic regurgitation were included to this study. Severity of aortic regurgitation was assessed with an aortic regurgitation index incorporating five echocardiographic parameters. Jet length/velocity ratio is calculated as the ratio of maximum jet penetrance to mean velocity of regurgitant flow. Jet length/velocity ratio was significantly higher in patients with severe aortic regurgitation (2.03 ± 0.53) compared to patients with less than severe aortic regurgitation (1.24 ± 0.32, P < 0.001). Correlation of jet length/velocity ratio with aortic regurgitation index was very good (r(2) = 0.86) and correlation coefficient was higher for jet length/velocity ratio compared to vena contracta, jet width/LVOT ratio and pressure half time. For a cutoff value of 1.61, jet length/velocity ratio had a sensitivity of 92% and specificity of 88%, with an AUC value of 0.955. Jet length/velocity ratio is a novel parameter that can be used to assess severity of chronic aortic regurgitation. Main limitation for usage of this novel parameter is jet impringement to left ventricular wall. © 2014, Wiley Periodicals, Inc.

Evaluation of the severity and the follow-up of aortic insufficiency (AI) are important tasks in paediatric cardiology. Assessment is based on clinical and echocardiographic (ECHO) findings such as the configuration of the valve and the regurgitation fraction (RF). The goal of this study was to evaluate MRI compared to ECHO for determination of clinical severity, valve morphology and RF. Thirty patients (age 3-27 years) with mild-to-severe AI were evaluated by clinical examination, ECHO (2-D and Doppler), and MRI at 1.5 T (2-D true-FISP cine short axis, phase-contrast flow in the ascending aorta). Both methods identified 13 bicuspid and 17 tricuspid valves. Good correlations between ECHO and cine MRI were found for ventricular mass, stroke volume, and ejection fraction. A good linear correlation was found for the RF determined by ECHO and phase-contrast MRI (r = 0.7). The RF was 6% in mild AI, 17% in moderate AI, and 30% in severe AI. The different severity groups showed significantly different RF and it was possible to discriminate between clinical severity grades (P = 0.01). ECHO and MRI showed good agreement in evaluating morphology and function of the left ventricle. The clinical severity of the disease can be evaluated correctly using MRI. (orig.)

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)

Quantitation of aortic and mitral regurgitation in the pediatric population: evaluation by radionuclide angiocardiography

The ability to quantitate aortic (AR) or mitral regurgitation (MR), or both, by radionuclide angiocardiography was evaluated in children and young adults at rest and during isometric exercise. Regurgitation was estimated by determining the ratio of left ventricular stroke volume to right ventricular stroke volume obtained during equilibrium ventriculography. The radionuclide measurement was compared with results of cineangiography, with good correlation between both studies in 47 of 48 patients. Radionuclide stroke volume ratio was used to classify severity: the group with equivocal regurgitation differed from the group with mild regurgitation (p less than 0.02); patients with mild regurgitation differed from those with moderate regurgitation (p less than 0.001); and those with moderate regurgitation differed from those with severe regurgitation (p less than 0.01). The stroke volume ratio was responsive to isometric exercise, remaining constant or increasing in 16 of 18 patients. After surgery to correct regurgitation, the stroke volume ratio significantly decreased from preoperative measurements in all 7 patients evaluated. Results from the present study demonstrate that a stroke volume ratio greater than 2.0 is compatible with moderately severe regurgitation and that a ratio greater than 3.0 suggests the presence of severe regurgitation. Thus, radionuclide angiocardiography should be useful for noninvasive quantitation of AR or MR, or both, helping define the course of young patients with left-side valvular regurgitation

Conclusion: The prevalence of inaudible valvular regurgitation is high in infants with structurally normal hearts. Multiple-valve involvement with regurgitation is not uncommon. Mild severity and low velocity on color Doppler, and the structural information provided by 2D imaging strongly suggest that these regurgitant flows are physiologically normal in infancy.

Traumatic tricuspid valve insufficiency. Experience in thirteen patients.

From 1964 through June 1993, thirteen patients with traumatic tricuspid insufficiency were treated surgically; all were male, and the ages ranged from 17 to 64 years (median 39 years). The condition was associated with blunt chest trauma in all patients: motor vehicle accidents in twelve and an explosion of a tank of compressed air in one. The median duration between trauma and operation was 17 years (range 1 month to 37 years). Preoperatively, six patients were in sinus rhythm and seven were in atrial fibrillation. At operation, the right ventricular function appeared moderately to severely depressed in twelve patients. In twelve patients, the anterior leaflet was flail because of chordal rupture (n = 9), rupture of anterior papillary muscle (n = 3), or tear in the anterior leaflet (n = 1). In one patient, the septal leaflet was missing and in another it was retracted and adherent to the ventricular septum. In five patients the tricuspid valve was repaired and in eight it was replaced. In seven patients in the latter group, the chordae, papillary muscles, and/or tricuspid valve leaflet(s) were found to be in a contracted and atrophic state, precluding repair. No early or late deaths occurred. At follow-up extending to 26 years (median 12 years), 12 patients are in New York Heart Association class I and one patient is in class II. Nine patients were in sinus rhythm and four were in atrial fibrillation. Although our experience indicates that good functional results can still be achieved many years after the onset of traumatic tricuspid valve insufficiency, earlier diagnosis and surgical treatment should increase the feasibility of tricuspid valve insufficiency, earlier diagnosis and surgical treatment should increase the feasibility of tricuspid valve repair, prevent progressive deterioration of right ventricular function, and increase the possibility of maintaining late sinus rhythm in a greater number of patients.

Diffuse Alveolar Hemorrhage due to Acute Mitral Valve Regurgitation

Directory of Open Access Journals (Sweden)

Creticus P. Marak

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.

Tricuspid valve disease has been neglected for a long time by cardiologists and surgeons, but for some years now leakage of tricuspid valve has been demonstrated as a prognostic factor in the evolution of patients with left heart valve disease undergoing surgery. Several techniques for plastic repair of tricuspid valve have been developed and the published studies differ on the results of these techniques; we conducted this study to assess the results of plastic repair of tricuspid valve in a population of patients with a high prevalence of rheumatic disease and to compare Carpentier's ring annuloplasty techniques with DEVEGA plasty. We conducted a retrospective study of patients undergoing plastic repair of tricuspid valve in the Department of Cardiology at the Medicine University of Sfax over a period of 25 years. We compared the results from the Group 1 (Carpentier's ring annuloplasty) with Group 2 (DeVEGA plasty). 91 patients were included in our study, 45 patients in the Group 1 and 46 patients in the Group 2. Most patients had mean or severe TI (83%) before surgery, ring dilation was observed in 90% of patients with no significant difference between the two groups. Immediate results were comparable between the two techniques but during monitoring recurrent, at least mean, insufficiency was significantly more frequent in the DeVEGA plasty Group. The predictive factors for significant recurring long term TI were DeVEGA technique (OR=3.26[1.12-9.28]) in multivariate study and preoperative pulmonary artery systolic pressure (OR=1.06 (1.01-1.12)). Plastic repair of tricuspid valve using Carpentier's ring seems to guarantee better results than DeVEGA plasty. On the other hand, preoperative high PASP is predictive of recurrent leakage of tricuspid valve even after plasty; hence the importance of surgery in the treatment of patients at an early stage of the disease.

We present the case of a 50-year old man who progressively developed tricuspid valve insufficiency with opening of a patent foramen ovale responsible for right-to-left shunt with polycythaemia. The tricuspid valve insufficiency was due to a foreign body, probably of surgical origin as suggested by its radiological image and by the patient's previous history. It would have been introduced, far away from the tricuspid valve (compound fracture of the wrist), several years previously. At surgery, we found the foreign body embedded in the valve system. As a possible mechanism for the mutilation, an undiagnosed endocarditis was suspected but could not be confirmed. Three cases tricuspid endocarditis (with foreign bodies in the right ventricle) and 3 cases of asymptomatic tricuspid valve foreign bodies have been published. Fifty-five cases of foreign bodies introduced peripherally and migrated into the heart, the pericardium and the pulmonary artery are reviewed.

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.

Exercise pulmonary hypertension in asymptomatic degenerative mitral regurgitation.

Magne, Julien; Lancellotti, Patrizio; Piérard, Luc A

2010-07-06

Current guidelines recommend mitral valve surgery for asymptomatic patients with severe degenerative mitral regurgitation and preserved left ventricular systolic function when exercise pulmonary hypertension (PHT) is present. However, the determinants of exercise PHT have not been evaluated. The aim of this study was to identify the echocardiographic predictors of exercise PHT and the impact on symptoms. Comprehensive resting and exercise transthoracic echocardiography was performed in 78 consecutive patients (age, 61+/-13 years; 56% men) with at least moderate degenerative mitral regurgitation (effective regurgitant orifice area =43+/-20 mm(2); regurgitant volume =71+/-27 mL). Exercise PHT was defined as a systolic pulmonary arterial pressure (SPAP) >60 mm Hg. Exercise PHT was present in 46% patients. In multivariable analysis, exercise effective regurgitant orifice was an independent determinant of exercise SPAP (Pexercise PHT (P=0.002). Resting PHT and exercise PHT were associated with markedly reduced 2-year symptom-free survival (36+/-14% versus 59+/-7%, P=0.04; 35+/-8% versus 75+/-7%, Pexercise PHT was identified as an independent predictor of the occurrence of symptoms (hazard ratio=3.4; P=0.002). Receiver-operating characteristics curves revealed that exercise PHT (SPAP >56 mm Hg) was more accurate than resting PHT (SPAP >36 mm Hg) in predicting the occurrence of symptoms during follow-up (P=0.032). Exercise PHT is frequent in patients with asymptomatic degenerative mitral regurgitation. Exercise mitral regurgitation severity is a strong independent predictor of both exercise SPAP and exercise PHT. Exercise PHT is associated with markedly low 2-year symptom-free survival, emphasizing the use of exercise echocardiography. An exercise SPAP >56 mm Hg accurately predicts the occurrence of symptoms.

Tricuspid valve insufficiency (TI) following cardiovascular surgery causes right-side heart failure and hepatic failure, which affect patient prognosis. Moreover, the benefits of reoperation for severe tricuspid insufficiency remain unclear. We investigated the surgical outcomes of reoperation in TI. From the Japan Cardiovascular Surgery Database (JACVSD), we extracted cases who underwent surgery for TI following cardiac surgery between January 2006 and December 2011. We analysed the surgical outcomes, specifically comparing tricuspid valve replacement (TVR) and tricuspid valve plasty (TVP). Of the 167 722 surgical JACVSD registered cases, reoperative TI surgery occurred in 1771 cases, with 193 TVR cases and 1578 TVP cases. The age and sex distribution was 684 males and 1087 females, with an average age of 66.5 ± 10.8 years. The overall hospital mortality was 6.8% and was significantly higher in the TVR group than in the TVP group (14.5 vs 5.8%, respectively; P tricuspid surgery were unsatisfactory. Although TVR is a last resort for non-repairable tricuspid lesions, it carries a significant risk of surgical mortality. Improving the patient's preoperative status and opting for TVP over TVR is necessary to improve the results of reoperative tricuspid surgery. © The Author 2014.

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%).

Tricuspid regurgitation (TR) is common in patients with heart failure undergoing left ventricular assist device (LVAD) implantation. Whether the TR should be surgically managed at the time of LVAD surgery is controversial. We searched SCOPUS, Web of Science, Ovid EMBASE, and Ovid MEDLINE (through May 10, 2014) for randomized controlled trials and observational studies comparing postoperative outcomes in patients treated with LVAD with concomitant tricuspid valve surgery (TVS) compared with LVAD alone. Six observational studies including 3,249 patients compared outcomes following LVAD + TVS versus LVAD. Four studies were single-center and most did not adjust for potential confounders. Addition of TVS prolonged cardiopulmonary bypass times by an average of 31 minutes (three studies, 95% CI 20-42). There was no difference in need for right ventricular assist device (six studies, HR 1.42, 95% CI 0.54-3.76), acute renal failure (four studies, HR 1.07, 95% CI 0.55-2.10), or early mortality (six studies, HR 1.28, 95% CI 0.78-2.08) in patients treated with LVAD + TVS versus LVAD alone. TVS prolongs cardiopulmonary bypass times, but available data demonstrate no significant association with early postoperative outcomes. However, differences in baseline risk of patients treated with TVS versus not limit our ability to draw conclusions.

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.

Can echocardiographic findings predict falls in older persons?

Directory of Open Access Journals (Sweden)

Nathalie van der Velde

Full Text Available BACKGROUND: The European and American guidelines state the need for echocardiography in patients with syncope. 50% of older adults with syncope present with a fall. Nonetheless, up to now no data have been published addressing echocardiographic abnormalities in older fallers. METHOD AND FINDINGS: In order to determine the association between echocardiographic abnormalities and falls in older adults, we performed a prospective cohort study, in which 215 new consecutive referrals (age 77.4, SD 6.0 of a geriatric outpatient clinic of a Dutch university hospital were included. During the previous year, 139 had experienced a fall. At baseline, all patients underwent routine two-dimensional and Doppler echocardiography. Falls were recorded during a three-month follow-up. Multivariate adjustment for confounders was performed with a Cox proportional hazards model. 55 patients (26% fell at least once during follow-up. The adjusted hazard ratio of a fall during follow-up was 1.35 (95% CI, 1.08-1.71 for pulmonary hypertension, 1.66 (95% CI, 1.01 to 2.89 for mitral regurgitation, 2.41 (95% CI, 1.32 to 4.37 for tricuspid regurgitation and 1.76 (95% CI, 1.03 to 3.01 for pulmonary regurgitation. For aortic regurgitation the risk of a fall was also increased, but non-significantly (hazard ratio, 1.57 [95% CI, 0.85 to 2.92]. Trend analysis of the severity of the different regurgitations showed a significant relationship for mitral, tricuspid and pulmonary valve regurgitation and pulmonary hypertension. CONCLUSIONS: Echo (Doppler cardiography can be useful in order to identify risk indicators for falling. Presence of pulmonary hypertension or regurgitation of mitral, tricuspid or pulmonary valves was associated with a higher fall risk. Our study indicates that the diagnostic work-up for falls in older adults might be improved by adding an echo (Doppler cardiogram in selected groups.

Contemporary Management of Ischemic Mitral Regurgitation: a Review.

Science.gov (United States)

Sandoval, Yader; Sorajja, Paul; Harris, Kevin M

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.

2013-11-01

Gastro-oesophageal reflux disease (GERD) is characterised by symptomatic heartburn and regurgitation. Treatment with proton pump inhibitors (PPI) effectively decreases heartburn symptoms, but their effects on symptomatic regurgitation are less clear. To determine the impact of PPI therapy on heartburn and regurgitation severity in patients with either non-erosive GERD (NERD) or erosive oesophagitis (EE). Endoscopically-confirmed NERD patients received dexlansoprazole 30 or 60 mg or placebo in a randomised, blinded, 4-week study. Endoscopically-confirmed EE patients received dexlansoprazole 60 mg or lansoprazole 30 mg in two 8-week, randomised, blinded healing studies. The Patient Assessment of Upper Gastrointestinal Symptom Severity questionnaire, which includes a heartburn/regurgitation subscale, was administered to assess symptom severity at baseline, and at weeks 2 and 4 of the NERD study and at weeks 4 and 8 during the EE trials. We defined separate subscales for heartburn and regurgitation for this post-hoc analysis. Among patients with both symptoms at baseline, improvements in individual heartburn and regurgitation subscales along with the original combined heartburn/regurgitation subscale were determined. In the NERD and EE studies, 661 and 1909 patients, respectively, had both heartburn and regurgitation at baseline. NERD patients receiving dexlansoprazole 30 and 60 mg experienced significantly greater improvements in symptom severity for both heartburn and regurgitation compared with placebo. EE patients receiving dexlansoprazole 60 mg had significantly greater improvements in heartburn/regurgitation and heartburn-only subscales at week 4 compared with those receiving lansoprazole. Dexlansoprazole appears to be effective in improving both heartburn and regurgitation, and this improvement is maintained for the duration of treatment. © 2013 John Wiley & Sons Ltd.

There is controversy about handling functional mitral regurgitation in patients undergoing aortic valve or proximal aortic operations. We describe a transaortic Alfieri edge-to-edge repair for functional mitral regurgitation that reduces operative excessive invasion and prolonged cardiopulmonary bypass time. Between May 2013 and December 2016, 10 patients underwent transaortic Alfieri edge-to-edge mitral repair. There were no operative deaths. The severity of mitral regurgitation immediately after the operation by transesophageal echocardiography was none or trivial in all patients. A transaortic Alfieri edge-to-edge repair for functional mitral regurgitation is a simple and safe approach. Copyright © 2018 The Society of Thoracic Surgeons. Published by Elsevier Inc.

We describe the first report of an Edwards SAPIEN valve implanted in a tricuspid bioprosthesis from the femoral vein. We highlight the feasibility of this previously avoided approach and the techniques involved. A 61-year-old woman with multiple valve replacements for rheumatic heart disease presented with NHYA IV dyspnoea secondary to a severely stenosed tricuspid bioprosthesis. After failed aggressive medical therapy and surgical turn down, an Edwards SAPIEN XT valve was deployed in the tricuspid bioprosthesis via the right femoral vein. Adaptations to the standard transfemoral transcatheter aortic valve implantation (TAVI) technique included: (1) crossing the tricuspid bioprosthesis with a balloon floatation catheter; (2) temporary pacing wire in the coronary sinus rather than the right ventricle; (3) mounting of the SAPIEN XT valve in the reverse orientation to transfemoral TAVI; and (4) fine positioning of the final valve position pre-deployment by 3D transoesophageal echocardiography (3D TOE) alone due to complete radiolucency of the tricuspid bioprosthesis. The procedure was completed without complication and resulted in significant symptomatic improvement. Deployment of an Edwards SAPIEN valve in a tricuspid bioprosthesis via the femoral vein is feasible and, with careful adaptations to established TAVI techniques, can be performed without complications and with good clinical response.

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

Science.gov (United States)

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

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.

Barlow disease represents a surgical challenge for mitral valve repair (MR) in the presence of mitral insufficiency (MI) with multiple regurgitant jets. We hereby present our mid-term experience using a modified edge-to-edge technique to address this peculiar MI. From March 2003 till December 2010, 25 consecutive patients (mean age 54 ± 7 years, 14 males) affected by severe Barlow disease with multiple regurgitant jets were submitted to MR. Preoperative transesophageal echo (TEE) in all the cases showed at least 2 regurgitant jets, involving one or both leaflets in more than one segment. In all the patients, a triple orifice valve (TOV) repair with annuloplasty was performed. Intra-operative TEE and postoperative transthoracic echocardiography (TTE) were carried out to evaluate results of the TOV repair. There was no in-hospital death and one late death (non-cardiac related). At intra-operative TEE, the three orifices showed a mean total valve area of 2.9 ± 0.1cm(2) (range 2.5-3.3 cm(2)) with no residual regurgitation (2 cases of trivial MI) and no sign of valve stenosis (mean transvalvular gradient 4.6 ± 1.5 mmHg). At follow up (mean 38 ± 22 months), TTE showed favourable MR and no recurrence of significant MI (6 cases of trivial and 1 of mild MI). Stress TTE was performed in 5 cases showing persistent effective valve function (2 cases of trivial MI at peak exercise). All the patients showed significant NYHA functional class improvement. This report indicates that the TOV technique is effective in correcting complex Barlow mitral valves with multiple jets. Further studies are required to confirm long-term applicability and durability in more numerous clinical cases. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Gerbode defect following endocarditis and misinterpreted as severe pulmonary arterial hypertension

Directory of Open Access Journals (Sweden)

Allajbeu Iris

2010-09-01

Full Text Available Abstract A Gerbode -type defect is a ventricular septal defect communicating directly between the left ventricle and right atrium. It is usually congenital, but rarely is acquired, as a complication of endocarditis. This can be anatomically possible because the normal tricuspid valve is more apically displaced than the mitral valve. However, identification of an actual communication is often extremely difficult, so a careful and meticulous echocardiogram should be done in order to prevent echocardiographic misinterpretation of this defect as pulmonary arterial hypertension. The large systolic pressure gradient between the left ventricle and the right atrium would expectedly result in a high velocity systolic Doppler flow signal in right atrium and it can be sometimes mistakably diagnosed as tricuspid regurgitant jet simulating pulmonary arterial hypertension. We present a rare case of young woman, with endocarditis who presented with severe pulmonary arterial hypertension. The preoperative diagnosis of left ventricle to right atrial communication (acquired Gerbode defect was suspected initially by echocardiogram and confirmed at the time of the surgery. A point of interest, apart from the diagnostic problem, was the explanation for its mechanism and presentation. The probability of a bacterial etiology of the defect is high in this case.

Full Text Available Mitral regurgitation is uncommon with left atrial myxoma. The echocardiographic assessment of presence of mitral regurgitation and its severity are impaired by the presence of left atrial myxoma. We describe an uncommon association of left atrial myxoma with coronary artery disease and mitral regurgitation. MR was reported as mild on pre-operative transthoracic echocardiography but found to be severe due to ruptured chordae tendinae during intra-operative transesophageal echocardiography, which lead to change in the surgical plan to mitral valve replacement in addition to excision of myxoma.

2008-10-01

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.

Dynamic MR images were obtained utilizing a repetition time of 21 msec, a 30-degree flip angle, and 12-msec gradient refocused echoes. Images were ECG-triggered and constructed at 16 images per cardiac cycle. To assess the sensitivity of dynamic MR imaging of valvular regurgitation, 17 patients were so examined and results were compared with results of echocardiography or cardiac catheterization. Mitral and tricuspid valves were well visualized in all patients. Regurgitation was demonstrated in 14 cases as an area of decreased signal extending from the valve into the regurgitant chamber, corresponding in time to ventricular systole for mitral and tricuspid regurgitation and diastole for aortic insufficiency. There were no false-negative MR imaging studies

[Department of Radiology, West China Hospital, Sichuan University, 37 Guo Xue Xiang, Chengdu, Sichuan 610041 (China)

Aim: To assess the severity of pure aortic regurgitation by measuring regurgitation volumes (RV) and fractions (RF) with dual-source computed tomography (DSCT) as compared to magnetic resonance imaging (MRI) and echocardiography. Materials and methods: Thirty-eight patients (15 men, 23 women; mean age 46 {+-} 11 years) with isolated aortic valve regurgitation underwent retrospectively electrocardiogram (ECG)-gated DSCT, echocardiography, and MRI. Stroke volumes of the left and right ventricles were measured at DSCT and MRI. Thus, RVs and RFs were calculated and compared. The agreement between DSCT and MRI was tested by intraclass correlation coefficient and Bland-Altman analyses. Spearman's rank order correlation and weighted {kappa} tests were used for testing correlations of AR severity between DSCT results and corresponding echocardiographic grades. Results: The RV and RF measured by DSCT were not significantly different from those measured using MRI (p = 0.71 and 0.79). DSCT correlated well with MRI for the measurement of RV (r{sub I} = 0.86, p<0.001) and calculation of the RF (r{sub I} =0.90, p<0.001). Good agreement between the techniques was obtained by using Bland-Altman analyses. The severity of regurgitation estimated by echocardiography correlated well with DSCT (r{sub s} = 0.95, p<0.001) and MRI (r{sub s} = 0.95, p<0.001). Inter-technique agreement between DSCT and two-dimensional transthoracic echocardiography (2DTTE) regarding the grading of the severity of AR was excellent ({kappa} = 0.90), and good agreement was also obtained between MRI and 2DTTE assessments of the severity of AR ({kappa} = 0.87). Conclusion: DSCT using a volume approach can be used to quantitatively determine the severity of pure aortic regurgitation when compared with MRI and echocardiography.

Treatment of severe mitral regurgitation caused by lesions in both leaflets using multiple mitral valve plasty techniques in a small dog

Full Text Available Mitral valve plasty (MVP is preferred over mitral valve replacement (MVR for mitral regurgitation in humans because of its favorable effect on quality of life. In small dogs, it is difficult to repair multiple lesions in both leaflets using MVP. Herein, we report a case of severe mitral regurgitation caused by multiple severe lesions in the posterior leaflet (PL in a mixed Chihuahua. Initially, we had planned MVR with an artificial valve. However, MVP combined with artificial chordal reconstruction of both leaflets, semicircular suture annuloplasty, and valvuloplasty using a newly devised direct scallop suture for the PL was attempted in this dog. The dog recovered well and showed no adverse cardiac signs, surviving two major operations. The dog died 4 years and 10 months after the MVP due to non-cardiovascular disease. Our additional technique of using a direct scallop suture seemed useful for PL repair involving multiple scallops in a small dog.

Intravenous administration of the vasodilator sodium nitroprusside has beneficial haemodynamic effects in subjects with severe aortic regurgitation while acute digitalisation can produce unwanted effects associated with an increase in systemic vascular resistance. This study compares the haemodynamic effects of the vasodilator prazosin and digoxin in eight patients with isolated severe aortic regurgitation. Prazosin 5 mg orally resulted in a 12 +/- 3 (SE) per cent increase in cardiac index (thermodilution), maintained over four to six hours, while digoxin 0.75 mg intravenously did not change the cardiac index. Prazosin reduced mean arterial pressure by 9 +/- 3 mmHg and systemic vascular resistance by 18 +/- 4 per cent while digoxin resulted in a 6 +/- 2 per cent increase in the latter. Mean pulmonary capillary wedge pressure fell 3 mmHg with prazosin. In this group of patients with severe aortic regurgitation but without severe cardiac failure, the changes with either drug, studied in doses conventionally used, were small but those with prazosin were directionally more desirable than those resulting from digoxin.

This study compares the medium-term results of De Vega, modified De Vega, and ring annuloplasty techniques for the correction of tricuspid insufficiency and investigates the risk factors for recurrent grades 3 and 4 tricuspid insufficiency after repair. In our clinic, 93 patients with functional tricuspid insufficiency underwent surgical tricuspid repair from May 2007 through October 2010. The study was retrospective, and all the data pertaining to the patients were retrieved from hospital records. Functional capacity, recurrent tricuspid insufficiency, and risk factors aggravating the insufficiency were analyzed for each patient. In the medium term (25.4 ± 10.3 mo), the rates of grades 3 and 4 tricuspid insufficiency in the De Vega, modified De Vega, and ring annuloplasty groups were 31%, 23.1%, and 6.1%, respectively. Logistic regression analysis revealed that chronic obstructive pulmonary disease, left ventricular dysfunction (ejection fraction, tricuspid insufficiency. Medium-term survival was 90.6% for the De Vega group, 96.3% for the modified De Vega group, and 97.1% for the ring annuloplasty group. Ring annuloplasty provided the best relief from recurrent tricuspid insufficiency when compared with DeVega annuloplasty. Modified De Vega annuloplasty might be a suitable alternative to ring annuloplasty when rings are not available.

Tricuspid valve endocarditis

Right-sided infective endocarditis (RSIE) is less common than left-sided infective endocarditis (IE), encompassing only 5–10% of cases of IE. Ninety percent of RSIE involves the tricuspid valve (TV). Given the relatively small numbers of TVIE cases operated on at most institutions, the purpose of this review is to highlight and discuss the current understanding of IE involving the TV. RSIE and TVIE are strongly associated with intravenous drug use (IVDU), although pacemaker leads, defibrillator leads and vascular access for dialysis are also major risk factors. Staphylococcus aureus is the predominant causative organism in TVIE. Most patients with TVIE are successfully treated with antibiotics, however, 5–16% of RSIE cases eventually require surgical intervention. Indications and timing for surgery are less clear than for left-sided IE; surgery is primarily considered for failed medical therapy, large vegetations and septic pulmonary embolism, and less often for TV regurgitation and heart failure. Most patients with an infected prosthetic TV will require surgery. Concomitant left-sided IE has its own surgical indications. Earlier surgical intervention may potentially prevent further destruction of leaflet tissue and increase the likelihood of TV repair. Fortunately, TV debridement and repair can be accomplished in most cases, even those with extensive valve destruction, using a variety of techniques. Valve repair is advocated over replacement, particularly in IVDUs patients who are young, non-compliant and have a higher risk of recurrent infection and reoperation with valve replacement. Excising the valve without replacing, it is not advocated; it has been reported previously, but these patients are likely to be symptomatic, particularly in cases with septic pulmonary embolism and increased pulmonary vascular resistance. Patients with concomitant left-sided involvement have worse prognosis than those with RSIE alone, due predominantly to greater likelihood of

Evaluation of mitral regurgitation by cine magnetic resonance imaging

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)

Traumatic Tricuspid Insufficiency Requiring Valve Repair in an Acute Setting.

Science.gov (United States)

Enomoto, Yoshinori; Sudo, Yoshio; Sueta, Tomonori

2015-01-01

Tricuspid insufficiency due to penetrating cardiac trauma is rare. Patients with tricuspid insufficiency due to trauma can tolerate this abnormality for months or even years. We report a case of a 66-year-old female with penetrating cardiac trauma on the right side of her heart that required tricuspid valve repair in an acute setting. She sustained cut and stab wounds on her bilateral forearms and in the neck and epigastric region. She had cardiac tamponade and developed pulseless electrical activity, which required emergency surgery. The right ventricle and superior vena cava were dissected approximately 5 cm and 2 cm, respectively. After these wounds had been repaired, the patient's inability to wean from cardiopulmonary bypass suggested rightsided heart failure; transesophageal echocardiography revealed tricuspid insufficiency. Right atriotomy was performed, and a detailed examination revealed that the tricuspid valve septal leaflet was split in two. There was also an atrial septal injury that created a connection with the left atrium; these injuries were not detected from the right ventricular wound. After repair, weaning from cardiopulmonary bypass with mild tricuspid insufficiency was achieved, and she recovered uneventfully. This case emphasized the importance of thoroughly investigating intracardiac injury and transesophageal echocardiography.

Full Text Available AbstractIntroduction:Left atrioventricular valve regurgitation is the most concerning residual lesion after surgical correction of atrioventricular septal defect.Objective:To determine factors associated with moderate or greater left atrioventricular valve regurgitation within 30 days of surgical repair of incomplete atrioventricular septal defect.Methods:We assessed the results of 51 consecutive patients 14 years-old and younger presenting with incomplete atrioventricular septal defect that were operated on at our practice between 2002 and 2010. The following variables were considered: age, weight, absence of Down syndrome, grade of preoperative left atrioventricular valve regurgitation, abnormalities on the left atrioventricular valve and the use of annuloplasty. The median age was 4.1 years; the median weight was 13.4 Kg; 37.2% had Down syndrome. At the time of preoperative evaluation, there were 23 cases with moderate or greater left atrioventricular valve regurgitation (45.1%. Abnormalities on the left atrioventricular valve were found in 17.6%; annuloplasty was performed in 21.6%.Results:At the time of postoperative evaluation, there were 12 cases with moderate or greater left atrioventricular valve regurgitation (23.5%. The variation between pre- and postoperative grades of left atrioventricular valve regurgitation of patients with atrioventricular valve malformation did not reach significance (P=0.26, unlike patients without such abnormalities (P=0.016. During univariate analysis, only absence of Down syndrome was statistically significant (P=0.02. However, after a multivariate analysis, none of the factors reached significance.Conclusion:None of the factors studied was determinant of a moderate or greater left atrioventricular valve regurgitation within the first 30 days of repair of incomplete atrioventricular septal defect in the sample. Patients without abnormalities on the left atrioventricular valve benefit more of the operation.

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.

Evaluation of valvular regurgitation by cine magnetic resonance imaging in patients with various cardiac diseases

1990-01-01

In order to evaluate the clinical value and limitation of magnetic resonance imaging (MRI) for detection and quantification of valvular regurgitation, 98 patients with various cardiac diseases were studied by cine MRI and the results were compared with contrast angiography and doppler color-flow imaging. Cine MRI was carried out using FLASH (fast low angle shot) which employs TE of 10∼20 msec and TR of 30∼40 msec. 22 transverse tomograms per cardiac cycle with a slice thickness of 10 mm were obtained at the level of atrium and ventricle. The jet of valvular regurgitation was easily seen as a discrete are of low signal with cine MRI. Identification of the regurgitation and its severity were visually evaluated based on the relative size of the regurgitant jet from the incompetent valve orifice. Using contrast angiography as a gold standard, the sensitivity of cine MRI for detecting mitral regurgitation was 83% and was 94% for aortic regurgitation, with the specificity of 82% and 100%, respectively. For mitral requrgitation and aortic regurgitation, evaluation by cine MRI and severity agreed well with contrast angiography. By the comparative study with doppler color-flow imaging, relatively good agreement was found between the two methods in detection and quantitative evaluation of valvular regurgitation in any of four valves. Cine MRI was suggested to be useful for both the detection and semiquantification of valvular regurgitation in generally, but its clinical limitation at this point was also found because, 1)its images are not acquired in real times, as in contrast angiography or doppler color-flow imaging, but are compiled from the cumulative information from 128 heart beats, 2)the evaluation of regurgitation is made from only two-dimensional transverse tomograms.

Huhta, James

2011-01-01

The natural history of congenitally corrected transposition of the great arteries is of clinical/surgical importance once the fetus is born without heart block or signs of heart failure. Without significant tricuspid valve malformation, associated defects such as ventricular septal defect and left ventricular outflow obstruction can be repaired surgically. The mortality and long-term outcome appear to be linked strongly with the severity of tricuspid valve regurgitation. Some patients with an intact ventricular septum and no right ventricular dysfunction will live long lives without detection, and some women will successfully complete pregnancy.

The purpose of our study was to assess the diagnostic accuracy of multislice computed tomography (MSCT) for the identification and quantification of mitral valve regurgitation in comparison with transthoracic echocardiography (TTE). Twenty-six patients (15 females, 11 males with a mean age of 44.6±14.1 years) who were in follow-up with the diagnosis of mitral regurgitation and those who were referred for MSCT were enrolled. MSCT results were compared with TTE measurements. The mean effective mitral regurgitant orifice area at MSCT was 23.1±13.0 mm 2 and at echocardiography was 24.4±16.0mm 2 . Bland-Altman analysis showed good agreement between the two imaging methods. MSCT provides reliable and good results for the evaluation of mitral regurgitation. (author)

Acquired tricuspid valve stenosis due to intentionally redundant transvenous lead placement for VDD pacing in two small dogs.

Gunther-Harrington, Catherine T; Michel, Adam O; Stern, Joshua A

2015-12-01

Placement of an endocardial VDD pacing lead in small dogs (stenosis in two small dogs between 8 months and 4 years after VDD pacemaker placement for third-degree atrioventricular block. Echocardiography and Doppler echocardiography identified elevated transtricuspid flow velocities, prolonged pressure half-times, decreased valve leaflet excursions, and tricuspid regurgitation in both cases. Both cases were euthanized secondary to this pacing complication. Necropsy was performed in one case and confirmed adherence between the redundant lead loop, atrial and valve tissue. While VDD pacing in dogs has proven hemodynamic benefits, these benefits have not been demonstrated in terms of survival benefit or clinical signs. The requirement of redundant lead placement in small dogs for appropriate VDD lead function creates potential deleterious effects that should be weighed against the possible clinical value of VDD pacing in these patients.

Aortic dilatation and dissection are severe complications during pregnancy that can be fatal to both the mother and the fetus. The risks of these complications are especially high in pregnant patients with Marfan syndrome; however, incidents of descending aortic dissection are very rare. This case report involves a successful Bentall procedure for and recovery from a rare aortic dissection in a pregnant Marfan patient who developed acute type II aortic dissection with severe aortic regurgitation and chronic descending aortic dissection immediately after Cesarean section. Regular follow-up will be needed to monitor the descending aortic dissection.

Lagrangian coherent structures in the left ventricle in the presence of aortic valve regurgitation

di Labbio, Giuseppe; Vetel, Jerome; Kadem, Lyes

2017-11-01

Aortic valve regurgitation is a rather prevalent condition where the aortic valve improperly closes, allowing filling of the left ventricle of the heart to occur partly from backflow through the aortic valve. Although studies of intraventricular flow are rapidly gaining popularity in the fluid dynamics research community, much attention has been given to the left ventricular vortex and its potential for early detection of disease, particularly in the case of dilated cardiomyopathy. Notably, the subsequent flow in the left ventricle in the presence of aortic valve regurgitation ought to be appreciably disturbed and has yet to be described. Aortic valve regurgitation was simulated in vitro in a double-activation left heart duplicator and the ensuing flow was captured using two-dimensional time-resolved particle image velocimetry. Further insight into the regurgitant flow is obtained by computing attracting and repelling Lagrangian coherent structures. An interesting interplay between the two inflowing jets and their shear layer roll-up is observed for various grades of regurgitation. This study highlights flow features which may find use in further assessing regurgitation severity.

Thompson, David S; Punjabi, Prakash P

2017-11-01

A 54-year-old gentleman presented with pulmonary oedema secondary to anterolateral papillary muscle (PPM) rupture and acute mitral regurgitation subsequent to myocardial ischaemia (MI). Angiography revealed complete occlusion of the first obtuse marginal (OM1) branch of the circumflex coronary artery and a 70% occlusion of the left anterior descending (LAD) coronary artery. Operatively, unusual anatomy was noted; an accessory head was attached superiorly to the anterior lateral PPM. This gave rise to chordae that were subsequently attached to the posterior second (P2) scallop. Additionally, the P2 scallop was deficient in chordae from the posteromedial PPM, thus, loss of this accessory head led to severe mitral regurgitation. We review the PPM anatomy and pathological context of PPM rupture and ischaemic mitral regurgitation.

Objective Ischemic mitral regurgitation is a predictor of heart failure resulting in increased mortality in patients with chronic myocardial infarction. It is uncertain whether the presence of papillary muscle (PM) infarction contributes to the development of mitral regurgitation in patients with chronic myocardial infarction (MI). The aim of the present study was to assess the correlation of PM infarction depicted by MRI with mitral regurgitation and left ventricular function. 48 patients with chronic MI and recent MRI and echocardiography were retrospectively included. The location and extent of MI depicted by MRI were correlated with left ventricular function assessed by MRI and mitral regurgitation assessed by echocardiography. The presence, location and extent of PM infarction depicted by late gadolinium enhancement (LGE-) MRI were correlated with functional parameters and compared with patients with chronic MI but no PM involvement. PM infarction was found in 11 of 48 patients (23 %) using LGE-MRI. 8/11 patients (73 %) with PM infarction and 22/37 patients (59 %) without PM involvement in MI had ischemic mitral regurgitation. There was no significant difference between location, extent of MI and presence of mitral regurgitation between patients with and without PM involvement in myocardial infarction. In 4/4 patients with complete and in 4/7 patients with partial PM infarction, mitral regurgitation was present. The normalized mean left ventricular end-diastolic volume was increased in patients with ischemic mitral regurgitation. The presence of PM infarction does not correlate with ischemic mitral regurgitation. In patients with complete PM infarction and consequent discontinuity of viable tissue in the PM-chorda-mitral valve complex, the probability of developing ischemic mitral regurgitation seems to be increased. However, the severity of mitral regurgitation is not increased compared to patients with partial or no PM infarction.

We present 2 cases of tricuspid insufficiency following blunt chest trauma: 1 was diagnosed 5 months after the trauma and the other, 20 years after the trauma. In both patients, the tricuspid valve was replaced with a porcine bioprosthesis, because valve repair was not considered feasible. These cases emphasize the variability of clinical presentation of post-traumatic tricuspid valve insufficiency and indicate the need for close follow-up of patients after major thoracic trauma.

Quantification of mitral regurgitation on cardiac computed tomography: comparison with qualitative and quantitative echocardiographic parameters.

LENUS (Irish Health Repository)

Arnous, Samer

2012-02-01

PURPOSE: To assess whether cardiac computed tomographic angiography (CCTA) can quantify the severity of chronic mitral regurgitation (MR) compared to qualitative and quantitative echocardiographic parameters. MATERIALS AND METHODS: Cardiac computed tomographic angiography was performed in 23 patients (mean +\\/- SD age, 63 +\\/- 16 years; range, 24-86 years) with MR and 20 patients without MR (controls) as determined by transthoracic echocardiography. Multiphasic reconstructions (20 data sets reconstructed at 5% increments of the electrocardiographic gated R-R interval) were used to analyze the mitral valve. Using CCTA planimetry, 2 readers measured the regurgitant mitral orifice area (CCTA ROA) during systole. A qualitative echocardiographic assessment of severity of MR was made by visual assessment of the length of the regurgitant jet. Quantitative echocardiographic measurements included the vena contracta, proximal isovelocity surface area, regurgitant volume, and estimated regurgitant orifice (ERO). Comparisons were performed using the independent t test, and correlations were assessed using the Spearman rank test. RESULTS: All controls and the patients with MR were correctly identified by CCTA. For patients with mild, moderate, or severe MR, mean +\\/- SD EROs were 0.16 +\\/- 0.03, 0.31 +\\/- 0.08, and 0.52 +\\/- 0.03 cm(2) (P < 0.0001) compared with mean +\\/- SD CCTA ROAs 0.09 +\\/- 0.05, 0.30 +\\/- 0.04, and 0.97 +\\/- 0.26 cm(2) (P < 0.0001), respectively. When echocardiographic measurements were graded qualitatively as mild, moderate, or severe, strong correlations were seen with CCTA ROA (R = 0.89; P < 0.001). When echocardiographic measurements were graded quantitatively, the vena contracta and the ERO showed modest correlations with CCTA ROA (0.48 and 0.50; P < 0.05 for both). Neither the proximal isovelocity surface area nor the regurgitant volume demonstrated significant correlations with CCTA ROA. CONCLUSIONS: Single-source 64-slice CCTA provides a

To investigate the impact of heartburn and regurgitation on the quality of life among patients with gastroesophageal reflux disease (GERD). Data from patients with GERD, who were diagnosed according to the Montreal definition, were collected between January 2009 and July 2010. The enrolled patients were assigned to a heartburn or a regurgitation group, and further assigned to an erosive esophagitis (EE) or a non-erosive reflux disease (NERD) subgroup, depending on the predominant symptoms and endoscopic findings, respectively. The general demographic data, the scores of the modified Chinese version of the GERDQ and the Short-form 36 (SF-36) questionnaire scores of these groups of patients were compared. About 108 patients were classified in the heartburn group and 124 in the regurgitation group. The basic characteristics of the two groups were similar, except for male predominance in the regurgitation group. Patients in the heartburn group had more sleep interruptions (22.3% daily vs 4.8% daily, P = 0.021), more eating or drinking problems (27.8% daily vs 9.7% daily, P = 0.008), more work interferences (11.2% daily vs none, P = 0.011), and lower SF-36 scores (57.68 vs 64.69, P = 0.042), than patients in the regurgitation group did. Individuals with NERD in the regurgitation group had more impaired daily activities than those with EE did. GERD patients with heartburn or regurgitation predominant had similar demographics, but those with heartburn predominant had more severely impaired daily activities and lower general health scores. The NERD cases had more severely impaired daily activity and lower scores than the EE ones did.

Grading of chronic aortic regurgitation (AR) and mitral regurgitation (MR) by cardiovascular magnetic resonance (CMR) is currently based on thresholds, which are neither modality nor quantification method specific. Accordingly, this study sought to identify CMR-specific and quantification method-specific thresholds for regurgitant volumes (RVols), RVol indexes, and regurgitant fractions (RFs), which denote severe chronic AR or MR with an indication for surgery. The study comprised patients with moderate and severe chronic AR (n = 38) and MR (n = 40). Echocardiography and CMR was performed at baseline and in all operated AR/MR patients (n = 23/25) 10 ± 1 months after surgery. CMR quantification of AR: direct (aortic flow) and indirect method (left ventricular stroke volume [LVSV] - pulmonary stroke volume [PuSV]); MR: 2 indirect methods (LVSV - aortic forward flow [AoFF]; mitral inflow [MiIF] - AoFF). All operated patients had severe regurgitation and benefited from surgery, indicated by a significant postsurgical reduction in end-diastolic volume index and improvement or relief of symptoms. The discriminatory ability between moderate and severe AR was strong for RVol >40 ml, RVol index >20 ml/m 2 , and RF >30% (direct method) and RVol >62 ml, RVol index >31 ml/m 2 , and RF >36% (LVSV-PuSV) with a negative likelihood ratio ≤ 0.2. In MR, the discriminatory ability was very strong for RVol >64 ml, RVol index >32 ml/m 2 , and RF >41% (LVSV-AoFF) and RVol >40 ml, RVol index >20 ml/m 2 , and RF >30% (MiIF-AoFF) with a negative likelihood ratio surgery.

Martin Tretjak

2015-06-01

Full Text Available AbstractBackground. Infectious endocarditis of the tricuspid valve is rare in non-intravenous drug users and patients without central venous devices. The most frequent causative agents are staphylococci, rarely other bacteria.Methods. We describe a case of a 57-year-old patient without history of drug abuse that was admitted to our hospital because of fever with chills, dry cough, loss of appetite and wasting lasting for a few months. He had a venous ulcer on the right foot and interdigital inflammation on both feet. Eikenella corrodens was isolated from blood cultures. Transthoracic echocardiography showed a large vegetation on the anterior leaflet of tricuspid valve. CT scan oh the thorax showed probable septic emboli. The patient was treated conservatively with prolonged double antibiotic regimen. During the treatment there were no further complications.Conclusions. In our patients a rare form of tricuspid valve endocarditis was confirmed, caused by Eikenella corrodens. The possibility of infectious endocarditis should always be considered in patients with prolonged fever, especially when a possible causative agent is isolated from blood cultures.

Diagnosis of tricuspid insufficiency by Doppler flowmetry in the inferior vena cava

International Nuclear Information System (INIS)

Smith, H.J.

1986-01-01

Eighty-five patients subjected to routine heart catheterization were examined with duplex scanning of the inferior vena cava. Adequate Doppler recordings and a right ventricular angiography were obtained in 79 of them. Tricuspid insufficiency was found to be present in 34 patients at angiography and in 24 at duplex examination. No false positive Doppler diagnoses of tricuspid insufficiency occurred. The possibility of false positive angiographic diagnoses is discussed. A high correlation was found between percentage reversed flow in the inferior vena cava during ventricular systole and degree of angiographic tricuspid insufficiency. It is concluded that duplex scanning of the inferior vena cava seems to be a good alternative to angiography in the diagnosis and quantification of tricuspid insufficiency. (orig.)

Acute severe mitral regurgitation (MR) is a serious medical condition. Whilst clear guidelines exist regarding the management of chronic MR, acute severe MR is usually treated on an individual basis. Currently, few data exist regarding acute MR in the era of primary coronary interventions (PCI). The present study included patients admitted to the Department of Cardiology during recent years with acute severe MR of different etiologies, and an analysis of these data in the light of previous investigations. The digital database of the present authors' hospital was searched for patients diagnosed with severe MR between 2008 and 2015. From a total of 228 patients identified, 19 with primary MR and 17 with secondary (functional) MR were admitted to the Department of Cardiology. The clinical data and outcome of these patients were analyzed. Among patients with MR due to acute myocardial infarction (MI), 13 had functional MR and six had MR due to mechanical complications, namely rupture of the papillary muscle or chordae tendineae. Among patients with MR not in the setting of MI, 13 had primary MR and four had functional MR. Patients with MR due to acute MI were more often in cardiogenic shock or had pulmonary edema and had a higher mortality. The strongest predictor of mortality was the presence of shock, followed by female gender, hypertension, age ≥68 years; previous MI and pulmonary edema were also predictors of mortality. In patients with acute MI and secondary MR, PCI to the culprit coronary artery was associated with a lesser degree of MR on follow up. Patients with severe MR are at high risk of in-hospital death. Patients with functional MR are likely to benefit from prompt PCI to the culprit artery, and for those with primary MR urgent surgery is life-saving.

Objectives The aim of this study was to test myocardial deformation imaging using speckle-tracking echocardiography for predicting outcomes in chronic aortic regurgitation. Background In chronic aortic regurgitation, left ventricular (LV) dysfunction must be detected early to allow timely surgery....... Speckle-tracking echocardiography has been proposed for this purpose, but the clinical value of this method in aortic regurgitation has not been established. Methods A longitudinal study was performed in 64 patients with moderate to severe aortic regurgitation. Thirty-five patients were managed...... conservatively with frequent clinical visits and sequential echocardiography and followed for an average of 19 ± 8 months, while 29 patients underwent surgery for the valve lesion and were followed for 6 months post-operatively. Baseline LV function by speckle-tracking and conventional echocardiography...

Left ventricular remodelling in chronic primary mitral regurgitation: implications for medical therapy.

Science.gov (United States)

McCutcheon, Keir; Manga, Pravin

Surgical repair or replacement of the mitral valve is currently the only recommended therapy for severe primary mitral regurgitation. The chronic elevation of wall stress caused by the resulting volume overload leads to structural remodelling of the muscular, vascular and extracellular matrix components of the myocardium. These changes are initially compensatory but in the long term have detrimental effects, which ultimately result in heart failure. Understanding the changes that occur in the myocardium due to volume overload at the molecular and cellular level may lead to medical interventions, which potentially could delay or prevent the adverse left ventricular remodelling associated with primary mitral regurgitation. The pathophysiological changes involved in left ventricular remodelling in response to chronic primary mitral regurgitation and the evidence for potential medical therapy, in particular beta-adrenergic blockers, are the focus of this review.

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

Science.gov (United States)

David, Tirone E

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.

Objective: To evaluate the value of echocardiography in investigation the failure of interventional therapy of VSDs and to increase the successful rate. Methods: 15 cases with failure of VSD closure through interventional approach were undertaken measurement of major parameters of the defect on left ventriculography and then followed by Philips 5500 color Doppler US for repeated multi-direction tangential measuring of the size, morphologic change, relation with peripheral structure and individual valvular regurgitation. Results: (1) Marginal membranous VSD 10 eases; membranance aneurysm 8 cases, ≥ 2 outlets 6 cases. Width of basal part of membranous aneurysm was 8-18 (10±2) mm with depth of 3 10 (6±2) mm, distance from aortic valve was 0-6 (2±1) mm and from tricuspid valve was 2-5 (2±1) mm; associated with slight tricuspid valvular regurgitation. Aortic valvular regurgitation 5 cases showed slight to mild amount and without membranous aneurysm occurred in 2 cases. (2) Intracristal VSD 5 cases showed the size of defect as 6-10 (7±1) mm, with distances of 2-3 (1±0.8) mm from pulmonary valve and 1-2 (1±0.6) mm from aortic valve associated with slight regurgitation in 4 cases, slight tricuspid valvular regurgitation in 5 eases and aortic valvular prolapse in 4 cases. Conclusions: Many factors can influence the direction tangential continuous scanning should be taken for accurate localization and measurement of VSD in order to select the very sight occludor providing high successful rate of occlusion and long term efficacy.

The study objective was to determine whether recurrent or residual mild aortic regurgitation, which occurs after valve-sparing aortic root replacement, progresses over time. Between 2003 and 2008, 154 patients underwent Tirone David-V valve-sparing aortic root replacement; 96 patients (62%) had both 1-year (median, 12 ± 4 months) and mid-term (62 ± 22 months) transthoracic echocardiograms available for analysis. Age of patients averaged 38 ± 13 years, 71% were male, 31% had a bicuspid aortic valve, 41% had Marfan syndrome, and 51% underwent aortic valve repair, predominantly cusp free margin shortening. Forty-one patients (43%) had mild aortic regurgitation on 1-year echocardiogram. In 85% of patients (n = 35), mild aortic regurgitation remained stable on the most recent echocardiogram (median, 57 ± 20 months); progression to moderate aortic regurgitation occurred in 5 patients (12%) at a median of 28 ± 18 months and remained stable thereafter; severe aortic regurgitation developed in 1 patient, eventually requiring reoperation. Five patients (5%) had moderate aortic regurgitation at 1 year, which did not progress subsequently. Two patients (2%) had more than moderate aortic regurgitation at 1 year, and both ultimately required reoperation. Although mild aortic regurgitation occurs frequently after valve-sparing aortic root replacement, it is unlikely to progress over the next 5 years and should not be interpreted as failure of the valve-preservation concept. Further, we suggest that mild aortic regurgitation should not be considered nonstructural valve dysfunction, as the 2008 valve reporting guidelines would indicate. We need 10- to 15-year follow-up to learn the long-term clinical consequences of mild aortic regurgitation early after valve-sparing aortic root replacement.

Aneurysmal dilation of the right ventricular outflow tract complicates assessment of right ventricular function in patients with repaired tetralogy of Fallot. Tricuspid annular plane systolic excursion is commonly used to estimate ejection fraction. We hypothesised that tricuspid annular plane systolic excursion measured by cardiac MRI approximates global and segmental right ventricular function, specifically right ventricular sinus ejection fraction, in children with repaired tetralogy of Fallot. Tricuspid annular plane systolic excursion was measured retrospectively on cardiac MRIs in 54 patients with repaired tetralogy of Fallot. Values were compared with right ventricular global, sinus, and infundibular ejection fractions. Tricuspid annular plane systolic excursion was indexed to body surface area, converted into a fractional value, and converted into published paediatric Z-scores. Tricuspid annular plane systolic excursion measurements had good agreement between observers. Right ventricular ejection fraction did not correlate with the absolute or indexed tricuspid annular plane systolic excursion and correlated weakly with fractional tricuspid annular plane systolic excursion (r=0.41 and p=0.002). Segmental right ventricular function did not appreciably improve correlation with any of the tricuspid annular plane systolic excursion measures. Paediatric Z-scores were unable to differentiate patients with normal and abnormal right ventricular function. Tricuspid annular plane systolic excursion measured by cardiac MRI correlates poorly with global and segmental right ventricular ejection fraction in children with repaired tetralogy of Fallot. Tricuspid annular plane systolic excursion is an unreliable approximation of right ventricular function in this patient population.

Although late-onset right-sided heart failure is recognized as a clinical problem in the treatment of patients with left ventricular assist devices (LVADs), the mechanism and predictors are unknown. Tricuspid valve (TV) deformation leads to the restriction of the leaflet motion and decreased coaptation, resulting in a functional tricuspid regurgitation that may act as a surrogate marker of late right-sided heart failure. This study aimed to investigate the association of preoperative TV deformation (annulus dilatation and leaflet tethering) with late right-sided heart failure development after continuous-flow LVAD implantation. The study cohort consisted of 274 patients who underwent 2-dimensional echocardiography before LVAD implantation. TV annulus diameter and tethering distance were measured in an apical 4-chamber view. Late right-sided heart failure was defined as right-sided heart failure requiring readmission and medical and/or surgical treatment after initial LVAD implantation. During a mean follow-up of 25.1 ± 19.0 months after LVAD implantation, late right-sided heart failure occurred in 33 patients (12.0%). Multivariate Cox proportional hazard analysis demonstrated that TV annulus diameter (hazard ratio 1.221 per 1 mm, p right-sided heart failure development, whereas leaflet tethering distance was not. The best cut-off value of the TV annular diameter was 41 mm (area under the curve 0.787). Kaplan-Meier analysis showed that patients with dilated TV annulus (TV annular diameter ≥41 mm) exhibited a significantly higher late right-sided heart failure occurrence than those without TV annular enlargement (log-rank p right-sided heart failure after LVAD implantation.

Tricuspid valve endocarditis following central venous cannulation: The increasing problem of catheter related infection

Directory of Open Access Journals (Sweden)

Suresh Babu Kale

2013-01-01

Full Text Available A central venous catheter (CVC is inserted for measurement of haemodynamic variables, delivery of nutritional supplements and drugs and access for haemodialysis and haemofiltration. Catheterization and maintenance are common practices and there is more to the technique than routine placement as evident when a procedure-related complication occurs. More than 15% of the patients who receive CVC placement have some complications and infectious endocarditis involving the tricuspid valve is a rare and serious complication with high morbidity and mortality. Overenthusiastic and deep insertion of the guide wire and forceful injection through the CVC may lead to injury of the tricuspid valve and predispose to bacterial deposition and endocarditis. We report a case of tricuspid valve endocarditis, probably secondary to injury of the anterior tricuspid leaflet by the guide wire or the CVC that required open heart surgery with vegetectomy and repair of the tricuspid valve.

In this study, we looked at the prognostic value of echocardiographic and hemodynamic measures in a large cohort of patients with precapillary pulmonary hypertension before and after initiation of treatment. Data were collected prospectively in a cohort of consecutive patients with precapillary pulmonary hypertension referred between 2002 and 2011. A range of clinical and echocardiographic variables were collected and stored on a database to assess predictors of survival. Invasive hemodynamic data including pulmonary artery pressure, pulmonary vascular resistance, capillary wedge pressure, and cardiac index were also obtained at baseline in all patients. Outcome was defined as mortality because of cardiovascular-related death. The study cohort comprised 777 patients (514 women) with precapillary pulmonary hypertension. A total of 195 (25%) died. In multivariable analysis, moderate or severe tricuspid regurgitation (hazard ratio [HR], 26.537; 95% confidence interval, 11.536-61.044; P<0.001), right ventricular myocardial performance index (HR, 3.421; 95% confidence interval, 1.777-6.584; P<0.001), and the presence of pericardial effusion (HR, 1.38; 95% confidence interval, 1.023-1.862; P=0.035) were independent predictors of mortality. High pulmonary vascular resistance and right atrial pressure by invasive hemodynamic measurements were independent predictors of mortality (HR, 1.084; 95% confidence interval, 1.041-1.130, and 1.079, respectively; 95% confidence interval, 1.049-1.111; P<0.001 for both), whereas patients with a higher cardiac index had better survival overall (HR, 0.384; 95% confidence interval, 0.307-0.481; P<0.001). Right ventricular dysfunction, moderate-severe tricuspid regurgitation, low cardiac index, and raised right atrial pressure were associated with poor survival for both pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertensive disease patients.

Many patients with left ventricular systolic dysfunction have concomitant mitral regurgitation (MR). Their symptoms and prognosis worsen with increasing severity of MR. Percutaneous MitraClip(®) can be used safely to reduce the severity of MR even in patients with advanced heart failure and is associated with improved symptoms, quality of life and exercise tolerance. However, a few patients with very poor left ventricular systolic function may experience significant haemodynamic disturbance in the peri-procedural period. We present three such patients, highlighting some of the potential problems encountered and discuss their possible pathophysiological mechanisms and safety measures.

Quantitative assessment of valvular regurgitation using radionuclide ventriculography

Shi Rongfang

1992-01-01

Radionuclide ventriculography has been used to assess quantitatively the extent of mitral and aortic regurgitation in 70 patients and compared to echocardiography and the finding of surgery. Two radionuclide parameters were measured: regurgitant index (RI) = left ventricular stroke counts/right ventricular stroke counts; and regurgitant fraction (RF) = left ventricular stroke counts-right ventricular stroke counts/left ventricular stroke counts. In 28 patients without valvular heart disease, the RI was 1.10 ± 0.15 and Rf was 10.3 ± 15.0%, respectively. However, in patients with valvular regurgitation, the RI and RF were 3.41 ± 1.73 and 61.1 ± 21.2%, respectively. A good correlation was found between the results obtained by radionuclide techniques and the findings of surgery and doppler studies. The level of concordance between RI and surgical findings was 91.7%. Follow up studies in 10 patients after valvular replacement surgery showed the RI and RF return to normal. These data suggested that radionuclide ventriculography is very useful for quantitative assessment of valvular regurgitation

Heart disease is the major cause of death as well as a leading cause of disability in the developed countries. Mitral Regurgitation (MR) is a common heart disease which does not cause symptoms until its end stage. Therefore, early diagnosis of the disease is of crucial importance in the treatment process. Echocardiography is a common method of diagnosis in the severity of MR. Hence, a method which is based on echocardiography videos, image processing techniques and artificial intelligence could be helpful for clinicians, especially in borderline cases. In this paper, we introduce novel features to detect micro-patterns of echocardiography images in order to determine the severity of MR. Extensive Local Binary Pattern (ELBP) and Extensive Volume Local Binary Pattern (EVLBP) are presented as image descriptors which include details from different viewpoints of the heart in feature vectors. Support Vector Machine (SVM), Linear Discriminant Analysis (LDA) and Template Matching techniques are used as classifiers to determine the severity of MR based on textural descriptors. The SVM classifier with Extensive Uniform Local Binary Pattern (ELBPU) and Extensive Volume Local Binary Pattern (EVLBP) have the best accuracy with 99.52%, 99.38%, 99.31% and 99.59%, respectively, for the detection of Normal, Mild MR, Moderate MR and Severe MR subjects among echocardiography videos. The proposed method achieves 99.38% sensitivity and 99.63% specificity for the detection of the severity of MR and normal subjects. Copyright © 2016 Elsevier Ltd. All rights reserved.

Guidelines for repair of bicuspid aortic valve-associated ascending thoracic aortic aneurysms have been changing, most recently to the same criteria as tricuspid aortic valve-ascending thoracic aortic aneurysms. Rupture/dissection occurs when wall stress exceeds wall strength. Recent studies suggest similar strength of bicuspid aortic valve versus tricuspid aortic valve-ascending thoracic aortic aneurysms; thus, comparative wall stress may better predict dissection in bicuspid aortic valve versus tricuspid aortic valve-ascending thoracic aortic aneurysms. Our aim was to determine whether bicuspid aortic valve-ascending thoracic aortic aneurysms had higher wall stresses than their tricuspid aortic valve counterparts. Patients with bicuspid aortic valve- and tricuspid aortic valve-ascending thoracic aortic aneurysms (bicuspid aortic valve = 17, tricuspid aortic valve = 19) greater than 4.5 cm underwent electrocardiogram-gated computed tomography angiography. Patient-specific 3-dimensional geometry was reconstructed and loaded to systemic pressure after accounting for prestress geometry. Finite element analyses were performed using the LS-DYNA solver (LSTC Inc, Livermore, Calif) with user-defined fiber-embedded material model to determine ascending thoracic aortic aneurysm wall stress. Bicuspid aortic valve-ascending thoracic aortic aneurysms 99th-percentile longitudinal stresses were 280 kPa versus 242 kPa (P = .028) for tricuspid aortic valve-ascending thoracic aortic aneurysms in systole. These stresses did not correlate to diameter for bicuspid aortic valve-ascending thoracic aortic aneurysms (r = -0.004) but had better correlation to tricuspid aortic valve-ascending thoracic aortic aneurysms diameter (r = 0.677). Longitudinal stresses on sinotubular junction were significantly higher in bicuspid aortic valve-ascending thoracic aortic aneurysms than in tricuspid aortic valve-ascending thoracic aortic aneurysms (405 vs 329 kPa, P = .023).

Symptomatically 'silent' gastro-oesophageal reflux disease (GORD) may be underdiagnosed. To determine the prevalence of untreated GORD without heartburn and/or regurgitation in primary care. Patients were included if they had frequent upper gastrointestinal symptoms and had not taken a proton pump inhibitor in the previous 2 months (Diamond study: NCT00291746). GORD was diagnosed based on the presence of reflux oesophagitis, pathological oesophageal acid exposure, and/or a positive symptom-acid association probability. Patients completed the Reflux Disease Questionnaire (RDQ) and were interviewed by physicians using a prespecified symptom checklist. GORD was diagnosed in 197 of 336 patients investigated. Heartburn and/or regurgitation were reported in 84.3% of patients with GORD during the physician interviews and in 93.4% of patients with GORD when using the RDQ. Of patients with heartburn and/or regurgitation not identified at physician interview, 58.1% (18/31) reported them at a 'troublesome' frequency and severity on the RDQ. Nine patients with GORD did not report heartburn or regurgitation either at interview or on the RDQ. Structured patient-completed questionnaires may help to identify patients with GORD not identified during physician interview. In a small proportion of consulting patients, heartburn and regurgitation may not be present in those with GORD.

Cine MR imaging in mitral valve prolapse; Study on mitral regurgitation and left atrial volume

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).

The aim of this study was to evaluate the degree of tricuspid valve insufficiency after orthotopic cardiac transplantation with bicaval anastomosis and prophylactic donor heart annuloplasty. At present, our cardiac transplantation experience includes 478 cases. After January 2002, we included 30 consecutive patients in this study who had undergone orthotopic cardiac transplantation and survived >6 months. The patients were divided into 2 groups: group I, 15 patients who underwent transplantation with prophylactic tricuspid annuloplasty on the donor heart with the De Vega technique; and group II, 15 patients who underwent transplantation without this procedure. Their preoperative clinical characteristics were the same. During the late postoperative follow-up, the degree of tricuspid insufficiency was evaluated by transthoracic Doppler echocardiography and assessed according to the Simpson scale: 0, absent; 1, mild; 2, moderate; and 3, severe. Hemodynamic parameters were evaluated invasively by means of a Swan-Ganz catheter during routine endomyocardial biopsies. The mean follow-up time was 26.9 +/- 5.4 months (range, 12-36 months). In group I, 1 patient (6.6%) died from infection in the 18th month after the operation; the death was not related to the annuloplasty. In group II, 1 death (6.6%) occurred after 10 months because of rejection (P > .05). After the 24-month follow-up, the mean degree of tricuspid insufficiency was 0.4 +/- 0.5 in group I and 1.7 +/- 0.9 in group II (P tricuspid annuloplasty on the donor heart was able to reduce significantly the degree of valvular insufficiency, even in cardiac transplantation with bicaval anastomosis; however, it did not modify significantly the hemodynamic performance of the allograft during the investigation period. It is very important to extend the observation period and casuistics to verify other benefits that this technique may offer.

Mitral Perivalvular Leak after Blunt Chest Trauma: A Rare Cause of Severe Subacute Mitral Regurgitation.

Marchese, Nicola; Facciorusso, Antonio; Vigna, Carlo

2015-12-01

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).

Since the amplitude value of a pixel is proportional to the stroke counts of the pixel, the total amplitude value of each ventricle would reflect its own stroke volume. Stroke count ratio (SCR) and ventricular amplitude ratio (VAR) values were simultaneously calculated and compared in 43 subjects, including 13 subjects with valvular regurgitation, after multigated equilibrium scintigraphy was performed. Mean values of SCR in 13 subjects with valvular regurgitation and 30 control subjects were 2.22+-1.11, 1.24+-0.41, respectively (p<0.005). Mean values of VAR were 2.52+-0.87, 1.36+-0.39, respectively (p<0.0005). The VAR method was independent of the tilting angles of the detector, and showed excellent intra-observer and inter-observer reproducibilities (r=0.95, r=0.91). The VAR method derived from the Fourier amplitude image is a noninvasive technique, is suitable for serial studies, and appears to be a relatively reliable means of assessing the severity of left-sided valvular regurgitation.

Objective: To explore the optimal project position for demonstrating tricuspid annulus angiographically in experimental goats. Methods: Eight healthy goats underwent right atrial angiography by using 6 F pig tail catheters. Under fluoroscopic monitoring the contrast media (total 110 ml, flow rate 12 ml/ s, pressure 800 psi) was injected continuously while a serious exposures were performed from RAO position to LAO position (totally 180 degree rotation). The maximum diameter of the tricuspid annulus in every picture was measured and the results were compared with that obtained from sonography. Results: The procedure was successful in all 8 experimental goats. The optimal project position to display the tricuspid annulus was at 27 degree ± 3 degree in RAO position. Conclusion: In angiography, the tricuspid annulus can be best demonstrated at the project position of 27 degree ± 3 degree in RAO. (authors)

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.

A systematic search of Medline, EMBASE and CINAHL electronic databases was performed. Original research articles reporting all-cause mortality following surgery in patients with aortic regurgitation and severe left ventricular systolic dysfunction (LVSD) were identified. Nine of the 10 eligible studies were observational, single-center, retrospective analyses. Survival ranged from 86 to 100% at 30 days; 81 to 100% at 1 year and 68 to 84% at 5 years. Three studies described an improvement in mean left ventricular ejection fraction (LVEF) following aortic valve replacement (AVR) of 5-14%; a fourth study reported an increase in mean left ventricular ejection fraction (LVEF) of 9% in patients undergoing isolated AVR but not when AVR was combined with coronary artery bypass graft and/or mitral valve surgery. Three studies demonstrated improvements in functional New York Heart Association (NYHA) class following AVR. Additional studies are needed to clarify the benefits of AVR in patients with more extreme degrees of left ventricular systolic dysfunction (LVSD) and the potential roles of cardiac transplantation and transaortic valve implantation.

Severe valvular heart disease is often complicated by congestive liver dysfunction, which greatly compromises the operative results. We evaluated congestive liver dysfunction by a novel approach using technetium-99m galactosyl human serum albumin ( 99m Tc-GSA) with liver scintigraphy. Between 1998 and 2004, we performed scintigraphy accompanied by 99m Tc-GSA in 28 patients who had valvular heart disease with moderate-to-severe tricuspid regurgitation and who showed symptoms of right heart failure. Based on the results, we calculated a receptor index (LHL15) and an index of blood clearance (HH15) and assessed the correlation between these factors and postoperative liver dysfunction, defined as the maximum serum total bilirubin level (max T-bil) as >2.0 mg/dl. Nineteen patients, including four who died in hospital, had postoperative liver dysfunction. The level of HH15 was significantly higher and the level of cholinesterase was significantly lower (P 99m Tc-GSA is a clinically useful predictor of postoperative liver dysfunction in patients with severe valvular disease.

Full Text Available Background. Carcinoid heart disease is a rare heart disease which affects endocard and heart valves on the right side of heart. It affects only patients with manifested carcinoid syndrome, which is thought to be the consequence of secretory active metastases of carcinoid tumour. The carcinoid endocardial plaques cause structural changes of tricuspid and pulmonic valve and later on their stenosis and/or insufficiency.Patients and methods. In this article we introduce a carcinoid valve heart disease (CVHD scoring system for easier end exact echocardiographic diagnostics. Four echocardiographic parameters are beeing estimated: structural changes of tricuspid valve, tricuspid valve regurgitation, stenosis of pulmonic valve and pulmonic valve regurgitation.Conclusions. The scoring system allows us to make an early diagnosis and evaluation of progression of carcinoid heart disease, which is very important for planning the treatment process. Our experiences confirm the usefulness of this scoring system in echocardiographic follow–up of patients with carcinoid syndrome.

2012-01-01

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.

Different techniques have been used for exposure of ventricular septal defect (VSD) margins when there is crowding of the VSD anatomy by tricuspid valve (TV) subvalvar apparatus. The aim of this study was to compare surgical outcomes, for the two techniques of TV leaflet detachment and the rarely described TV chordal detachment for hard-to-expose VSDs. Patients undergoing transatrial VSD repair were identified from our institutional database. Follow-up echocardiography and patient data were obtained from medical records. Between 1/2005-8/2016, 130 isolated conoventricular VSDs were repaired. Among these, 26patients had leaflet detachment, while 15 underwent chordal detachment, and 89 had regular VSD repair (reference group). There was no significant difference between the groups in age, weight, postoperative length-of-stay, genetic/syndromic abnormalities, time-to-extubation, and left and right ventricular systolic function. The cardiopulmonary bypass and cross-clamp time were significantly higher in leaflet detachment group, when compared with reference group (118+28vs102+32, p=0.02; and 73+20vs61+23, p=0.01, respectively). Echocardiographic follow-up were available for 87patients at a mean of 2.6years (1month-11years). Tricuspid regurgitation was rated as none or trivial in 66(76%), mild in 20(23%) and moderate in one reference group patient. There was no difference in presence of residual VSD, or degree of tricuspid regurgitation amongst the three groups. There was no reoperation for tricuspid regurgitation. Tricuspid valve leaflet and chordal detachment techniques provide equally viable and safe alternative to closure of hard-to-expose VSDs while maintaining appropriate TV function. Their use in our series did not lead to increased TV dysfunction at early-to-midterm echocardiographic assessment. Copyright © 2018. Published by Elsevier Inc.

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.

Postoperative course was complicated by tricuspid valve thrombosis and secondary pulmonary embolism requiring TPA thrombolysis which was instantly successful. A review of literature of pacemaker endocarditis and tricuspid thrombosis along with the relevant management strategies is presented. We believe this case report is unusual on account of non operative management of right atrial lead perforation following an unsuccessful attempt at percutaneous removal of right sided infected pacemaker leads and the incidental discovery of the perforated lead 13 years later at sternotomy, presentation of pacemaker endocarditis with a massive load of vegetations along the entire pacemaker lead tract in superior vena cava, right atrial endocardium, tricuspid valve and right ventricular endocardium, leading to a functional and structural SVC obstruction, requirement of an unusually large dose of warfarin postoperatively occasioned, in all probability, by antibiotic drug interactions, presentation of tricuspid prosthetic valve thrombosis uniquely as vasovagal syncope and isolated hypoxia and near instantaneous resolution of tricuspid prosthetic valve thrombosis with Alteplase thrombolysis.

2015-07-01

Full Text Available A middle aged man presented with evidence of right - sided heart failure in atrial fibrillation (AF and was found to have severe Tricuspid Regurgitation (TR with pulmonary artery hypertension (PAH, with normal left ventricular function. The common possible seconda ry causes of PAH were ruled out, but during investigation he was found to have elevated thyroid function tests compatible with the diagnosis of Graves’ disease. The treatment of Graves’ disease was started with anti - thyroid drugs and associated with a sign ificant reduction in the pulmonary arterial pressure. This case report is presented to highlight one of the rare and underdiagnosed presentations of Graves’ disease. Thyrotoxicosis can present with profound cardiovascular complications. In recent times, th ere have been few reports of secondary PAH with TR in patients with hyperthyroidism. Previously asymptomatic Graves’ disease having the signs and symptoms of right heart failure is a rare presentation and the association could be easily missed. This case p resentation emphasizes that the diagnosis of thyroid heart disease with heart failure secondary to Graves’ disease should be considered in any patient regardless of age, gender with clinical features of heart failure of unknown etiology and timely initiation of anti - thyroid drugs is necessary to treat these reversible cardiac failures.

Evaluation of aortic regurgitation using cine magnetic resonance imaging

International Nuclear Information System (INIS)

Tamai, Takuya; Konishi, Tokuji; Okamoto, Shinya; Sakuma, Hajime; Takeda, Kan; Nakano, Takeshi

1993-01-01

Cine magnetic resonance imaging (MRI) was used to assess aortic regurgitation (AR) in 13 patients with valvular disease and 3 normal subjects, and the results were compared to color Doppler flow mapping findings. AR produced a signal void in the left ventricle during the diastolic phase in all patients by MRI. There were no false positive or negative results compared with echocardiographic findings. Visual grading of cine MRI gave results similar to color flow Doppler echocardiography (88%). The distance and the area of aortic regurgitation using MRI correlated well with color Doppler flow mapping (r=0.82 and 0.88). However, measurements of distance and area by color flow Doppler tended to be larger than those by cine MRI. With current techniques echocardiography may overestimate the severity of AR as compared with cine MRI. In addition, MRI gives clinically useful information in patients in whom transthoracic Doppler echocardiography is not adequate. (author)

Introduction: Although valve repair is applied routinely nowadays, particularly for mitral regurgitation (MR) or tricuspid regurgitation (TR), valve replacement using prosthetic valves is also common especially in adults. Unfortunately the valve with ideal hemodynamic performance and long-term durability without increasing the risk of bleeding due to long-term anticoagulant therapy has not been introduced. Therefore, patients and physicians must choose either bioprosthetic or mechanical valve...

[ESC guidelines on the management of valvular heart disease. What has changed and what is new?].

Science.gov (United States)

Mangner, N; Schuler, G

2013-12-01

In 2012 the new and collaborative "Guidelines on the management of valvular heart disease (version 2012)" were published by the European Society of Cardiology (ESC) and the European Association for Cardio-Thoracic Surgery (EACTS). These guidelines emphasize that decision-making in patients with valvular heart disease should ideally be carried out by a"heart team" with particular expertise in valvular heart disease. In aortic regurgitation pathologies of the aortic root are frequent and in patients with Marfan syndrome, surgery is indicated when the maximal ascending aortic diameter is ≥50 mm, while the threshold for intervention should be lower in patients with risk factors for progression. Regarding aortic stenosis, transcatheter aortic valve implantation (TAVI) should be performed only in hospitals with on-site cardiac surgery and with a"heart team" available to assess patient risks. The TAVI procedure is indicated in patients with severe symptomatic aortic stenosis who are judged by the"heart team" to be unsuitable for surgery but have sufficient life expectancy. It should be considered for high-risk patients with severe symptomatic aortic stenosis based on the individual risk profile assessed by the"heart team". Furthermore, low flow - low gradient aortic stenosis with normal ejection fraction and the difficult topic of asymptomatic severe aortic stenosis and the indications for aortic valve replacement are discussed. With respect to mitral regurgitation, valve repair should be the preferred technique when it is expected to be durable. The topics of asymptomatic mitral regurgitation as well as percutaneous mitral valve repair using the edge to edge technique as an alternative for high risk patients are discussed. Tricuspid disease should not be forgotten and during left-sided valve surgery, tricuspid valve surgery should be considered in the presence of mild to moderate secondary regurgitation if there is significant annular dilatation.

Evaluation of Tricuspid Annular Plane Systolic Excursion Measured with Cardiac Magnetic Resonance Imaging in Pediatric Patients with Tetralogy of Fallot

Science.gov (United States)

Soslow, Jonathan H.; Usoro, Emem; Wang, Li; Parra, David A.

2015-01-01

Background Aneurysmal dilation of the right ventricular outflow tract complicates assessment of right ventricular function in patients with repaired tetralogy of Fallot. Tricuspid annular plane systolic excursion is commonly used to estimate ejection fraction. We hypothesized that tricuspid annular plane systolic excursion measured by cardiac magnetic resonance imaging approximates global and segmental right ventricular function, specifically right ventricular sinus ejection fraction, in pediatric patients with repaired tetralogy of Fallot. Methods Tricuspid annular plane systolic excursion was measured retrospectively on cardiac magnetic resonance images in 54 patients with repaired tetralogy of Fallot. Values were compared with right ventricular global, sinus, and infundibular ejection fractions. Tricuspid annular plane systolic excursion was: 1) indexed to body surface area, 2) converted into a fractional value, and 3) converted into published pediatric Z-scores. Results Tricuspid annular plane systolic excursion measurements had good agreement between observers. Right ventricular ejection fraction did not correlate with the absolute or indexed tricuspid annular plane systolic excursion and correlated weakly with fractional tricuspid annular plane systolic excursion (r=0.41 and p=0.002). Segmental right ventricular function did not appreciably improve correlation with any of the tricuspid annular plane systolic excursion measures. Pediatric Z-scores were unable to differentiate patients with normal and abnormal right ventricular function. Conclusions Tricuspid annular plane systolic excursion measured on cardiac magnetic resonance imaging correlates poorly with global and segmental right ventricular ejection fraction in pediatric patients with repaired tetralogy of Fallot. Tricuspid annular plane systolic excursion is an unreliable approximation of right ventricular function in this patient population. PMID:26279488

Reduction of regurgitation in aortic insufficiency by inhibition of the renin/angiotensin conversion enzyme

Energy Technology Data Exchange (ETDEWEB)

Reske, S.N.; Heck, I.; Mattern, H.

1984-10-01

The effect of captopril-mediated afterload reduction on regurgitation was investigated in 10 patients with aortic insufficiency. Regurgitation was quantitated by the regurgitation fraction and the relation of regurgitant volume to end-diastolic volume, which were derived from gated radionuclide ventriculography. 19 patients with coronary artery disease and no evidence of valvular heart disease served as controls. In patients with coronary artery disease no significant reguration was found. In patients with aortic regurgitation the blood concentration of angiotensin I increased whereas that of angiotensin II decreased significantly after captopril-medication; thus, the conversion of angiotensin I to II was reduced to about 50% of the control value. Whereas blood pressure and heart rate did not change significantly, the regurgitation fraction and the normalized regurgitant volume were significantly reduced. The ejection fraction remained essentially unchanged. These findings suggest a favorable influence of captopril-induced afterload reduction on hemodynamics in aortic regurgitation.

Overestimation of the severity of mitral regurgitation (MR) by the proximal isovelocity surface area (PISA) method has been reported. We sought to test whether angle correction (AC) of the constrained flow field is helpful to eliminate overestimation in patients with eccentric MR. In a total of 33 patients with MR due to prolapse or flail mitral valve, both echocardiography and cardiac magnetic resonance image (CMR) were performed to calculate regurgitant volume (RV). In addition to RV by conventional PISA (RV PISA ), convergence angle (α) was measured from 2-dimensional Doppler color flow maps and RV was corrected by multiplying by α/180 (RV AC ). RV measured by CMR (RV CMR ) was used as a gold standard, which was calculated by the difference between total stroke volume measured by planimetry of the short axis slices and aortic stroke volume by phase-contrast image. The correlation between RV CMR and RV by echocardiography was modest [RV CMR vs. RV PISA (r = 0.712, p < 0.001) and RV CMR vs. RV AC (r = 0.766, p < 0.001)]. However, RV PISA showed significant overestimation (RV PISA - RV CMR = 50.6 ± 40.6 mL vs. RV AC - RV CMR = 7.7 ± 23.4 mL, p < 0.001). The overall accuracy of RV PISA for diagnosis of severe MR, defined as RV ≥ 60 mL, was 57.6% (19/33), whereas it increased to 84.8% (28/33) by using RV AC ( p = 0.028). Conventional PISA method tends to provide falsely large RV in patients with eccentric MR and a simple geometric AC of the proximal constraint flow largely eliminates overestimation.

Cardiovascular complications induced by adjuvant cancer therapies may become symptomatic after many years, being responsible for increased morbidity and mortality in long-term survivors. We report a case of a 54-year old female admitted for severe heart failure induced by myocardial and valvular damage after postoperative adjuvant therapy for left breast cancer 6 years ago. Her recent history revealed nonST elevation myocardial infarction in the absence of significant cardiovascular risk factors. Transthoracic echocardiography, tissue Doppler imaging and speckle-tracking imaging revealed severe biventricular systolic dysfunction, severe mitral and tricuspid regurgitation and severe pulmonary hypertension.

This study sought to examine a possible relationship between the severity of aortic valve calcification (AVC), the distribution of AVC and the degree of aortic valve regurgitation (AR) after transcatheter aortic valve implantation (TAVI) for severe aortic stenosis (AS). 57 patients (22 men, 81 ± 5 years) with symptomatic AS and with a logistic EuroSCORE of 24 ± 12 were included. 38 patients (67%) received a third (18F)-generation CoreValve® aortic valve prosthesis, in 19 patients (33%) an Edwards SAPIEN™ prosthesis was implanted. Prior to TAVI dual-source computed tomography for assessment of AVC was performed. To determine the distribution of AVC the percentage of the calcium load of the most severely calcified cusp was calculated. After TAVI the degree of AR was determined by angiography and echocardiography. The severity of AR after TAVI was related to the severity and distribution of AVC. There was no association between the distribution of AVC and the degree of paravalvular AR after TAVI as assessed by angiography (r = -0.02, p = 0.88). Agatston AVC scores were significantly higher in patients with AR grade ≥ 3 (5055 ± 1753, n = 3) than in patients with AR grade AVC scores > 3000 were associated with a relevant paravalvular AR and showed a trend for increased need for second manoeuvres. There was a significant correlation between the severity of AVC and the degree of AR after AVR (r = 0.50, p AVC have an increased risk for a relevant AR after TAVI as well as a trend for increased need for additional procedures.

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.

European Respiratory Society (ERS) guidelines recommend the assessment of patients with interstitial lung disease (ILD) and severe pulmonary hypertension (PH), as defined by a mean pulmonary artery pressure (mPAP) ≥35 mmHg at right heart catheterisation (RHC). We developed and validated a stepwise echocardiographic score to detect severe PH using the tricuspid regurgitant velocity and right atrial pressure (right ventricular systolic pressure (RVSP)) and additional echocardiographic signs. Consecutive ILD patients with suspected PH underwent RHC between 2005 and 2015. Receiver operating curve analysis tested the ability of components of the score to predict mPAP ≥35 mmHg, and a score devised using a stepwise approach. The score was tested in a contemporaneous validation cohort. The score used "additional PH signs" where RVSP was unavailable, using a bootstrapping technique. Within the derivation cohort (n=210), a score ≥7 predicted severe PH with 89% sensitivity, 71% specificity, positive predictive value 68% and negative predictive value 90%, with similar performance in the validation cohort (n=61) (area under the curve (AUC) 84.8% versus 83.1%, p=0.8). Although RVSP could be estimated in 92% of studies, reducing this to 60% maintained a fair accuracy (AUC 74.4%). This simple stepwise echocardiographic PH score can predict severe PH in patients with ILD.

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.

The aim of this study was to identify the morphological and functional characteristics of quadricuspid aortic valves (QAV) on cardiac computed tomography (CCT). We retrospectively enrolled 11 patients with QAV. All patients underwent CCT and transthoracic echocardiography (TTE), and 7 patients underwent cardiovascular magnetic resonance (CMR). The presence and classification of QAV assessed by CCT was compared with that of TTE and intraoperative findings. The regurgitant orifice area (ROA) measured by CCT was compared with severity of aortic regurgitation (AR) by TTE and the regurgitant fraction (RF) by CMR. All of the patients had AR; 9 had pure AR, 1 had combined aortic stenosis and regurgitation, and 1 had combined subaortic stenosis and regurgitation. Two patients had a subaortic fibrotic membrane and 1 of them showed a subaortic stenosis. One QAV was misdiagnosed as tricuspid aortic valve on TTE. In accordance with the Hurwitz and Robert's classification, consensus was reached on the QAV classification between the CCT and TTE findings in 7 of 10 patients. The patients were classified as type A (n = 1), type B (n = 3), type C (n = 1), type D (n = 4), and type F (n = 2) on CCT. A very high correlation existed between ROA by CCT and RF by CMR (r = 0.99) but a good correlation existed between ROA by CCT and regurgitant severity by TTE (r = 0.62). Cardiac computed tomography provides comprehensive anatomical and functional information about the QAV.

Regurgitation in healthy and non healthy infants

Full Text Available Abstract Uncomplicate regurgitation in otherwise healthy infants is not a disease. It consists of milk flow from mouth during or after feeding. Common causes include overfeeding, air swallowed during feeding, crying or coughing; physical exam is normal and weight gain is adequate. History and physical exam are diagnostic, and conservative therapy is recommended. Pathologic gastroesophageal reflux or gastroesophageal reflux disease refers to infants with regurgitation and vomiting associated with poor weight gain, respiratory symptoms, esophagitis. Reflux episodes occur most often during transient relaxations of the lower esophageal sphincter unaccompanied by swallowing, which permit gastric content to flow into the esophagus. A minor proportion of reflux episodes occurs when the lower esophageal sphincter fails to increase pressure during a sudden increase in intraabdominal pressure or when lower esophageal sphincter resting pressure is chronically reduced. Alterations in several protective mechanisms allow physiologic reflux to become gastroesophageal reflux disease; diagnostic approach is both clinical and instrumental: radiological series are useful to exclude anatomic abnormalities; pH-testing evaluates the quantity, frequency and duration of the acid reflux episodes; endoscopy and biopsy are performed in the case of esophagitis. Therapy with H2 receptor antagonists and proton pump inhibitors are suggested.

Full Text Available Symptomatic pulmonary arterial hypertension (PAH in patients with isolated atrial septal defect (ASD is rare during infancy. We report a case of isolated ASD with severe PAH in an infant who developed airway obstruction as cardiomegaly progressed. The patient presented with recurrent severe respiratory insufficiency and failure to thrive before the repair of the ASD. Echocardiography confirmed volume overload on the right side of heart and severe PAH (tricuspid regurgitation [TR] with a peak pressure gradient of 55 to 60 mmHg. The chest radiographs demonstrated severe collapse of both lung fields, and a computed tomography scan showed narrowing of the main bronchus because of an intrinsic cause, as well as a dilated pulmonary artery compressing the main bronchus on the left and the intermediate bronchus on the right. ASD patch closure was performed when the infant was 8 months old. After the repair of the ASD, echocardiography showed improvement of PAH (TR with a peak pressure gradient of 22 to 26 mmHg, and the patient has not developed recurrent respiratory infections while showing successful catch-up growth. In infants with symptomatic isolated ASD, especially in those with respiratory insufficiency associated with severe PAH, extrinsic airway compression should be considered. Correcting any congenital heart diseases in these patients may improve their symptoms.

The main clinical manifestations of Whipple's disease are weight loss, arthropathy, diarrhea and abdominal pain. Cardiac involvement is frequently described. However, endocarditis is rare and is not usually the initial presentation of the disease. To the best of our knowledge, this is the first reported case of a patient with Tropheryma whipplei tricuspid endocarditis without any other valve involved and not presenting signs of arthralgia and abdominal involvement. We report a case of a 50-year-old Caucasian man with tricuspid endocarditis caused by Tropheryma whipplei, showing signs of severe shock and an absence of other more classic clinical signs of Whipple's disease, such as arthralgia, abdominal pain and diarrhea. Tropheryma whipplei was documented by polymerase chain reaction of the blood and pleural fluid. The infection was treated with a combined treatment of doxycycline, hydroxychloroquine and sulfamethoxazole-trimethoprim for one year. Tropheryma whipplei infectious endocarditis should always be considered when facing a blood-culture negative endocarditis particularly in right-sided valves. Although not standardized yet, treatment of Tropheryma whipplei endocarditis should probably include a bactericidal antibiotic (such as doxycycline) and should be given over a prolonged period of time (a minimum of one year).

.3 years, all were in Functional Class III or IV (NYHA, with increased cyanoses and frequent rhythm disturbance. Four patients had an associated atrioventricular septal defect; in four patients the tricuspid valve was Carpentier's type B and two type A and all were able to benefit from this conservative technique. RESULTS: There were not hospital deaths and one patient died 14º months after surgery in this series. Actuarial survival was 83.3% in 9 years. Four patients are in Functional Class I and one in Functional Class II (NYHA. Echocardiography and Doppler studies demonstrated a normal shape of right ventricle and good tricuspid valve function in four patients and one has moderate tricuspid regurgitation but still in Functional Class II (NYHA. CONCLUSION: Although the small number of patients in this series, the modification of Carpentier's repair technique in adult patients was efficient, reproducible and improved the preoperative status with regard to functional class, tricuspid regurgitation cyanoses and rhythm disturbance.

An isolated single coronary artery can be associated with normal life expectancy; however, patients are at an increased risk of sudden death. A case is reported of a 54-year-old man with several months of chest pressure with activity. On exercise Sestamibi stress testing, the patient developed a hypotensive response with no symptoms and minimal electrocardiographic changes. Nuclear scanning demonstrated reversible septal and lateral perfusion defects consistent with severe ischemia. Coronary angiography revealed a single coronary artery with the right coronary artery arising from the left main. There were high-grade stenotic lesions in the left anterior descending and circumflex arteries with only moderate atherosclerotic disease in the right coronary artery. An aortogram showed 2-3+ aortic regurgitation, with an ejection fraction of 45% on ventriculography. The patient underwent four-vessel revascularization and aortic valve replacement and did well postoperatively

Using cardiac computed tomography (CT), the ''mean'' volume of each cardiac chamber and both ventricular masses were calculated from summation of a sliced volume by ungated scans obtained using rapid sequential scanning covering the whole heart. 1. Estimation of a normal value of each chamber's volume was attempted in 20 patients with ischemic heart disease and with normal heart function. The ''mean'' volume of the right atrium (RAMV), right ventricle (RVMV), and left atrium (LAMV) was 22.3 +- 6.5, 40.3 +- 6.5 and 28.7 +- 8.2ml/m 2 , respectively. 2. In 54 patients with valvular heart diseases, each chamber's volume obrained by CT was compared with the grade of tricuspid regurgitation (TR) estimated by ultrasonic Doppler technique or the grade of mitral regurgitation (MR) by left ventriculography (LVG). The RAMV (234 +- 119 ml/m 2 ) and the RVMV (101 +- 39 ml/m 2 ) were markedly increased in patients with severe TR (grade 3 to 4) (p 2 ) was also increased in patients with severe mitral regurgitation (grade 3 to 4) (p<0.01). 3. In 46 patients with valvular heart diseases, the LVMV by CT was well correlated with end-diastolic volume (EDV) obtained by LVG (r=0.92), and the LVEDVs by ECG gated CT and by LVG showed a fairly good correlation (r=0.95). 4. CT examination was performed before and after surgery in 17 patients with MR or TR for evaluation of the change of chamber volumes. The mean reduction ratio (MRR) of the RAMV after tricuspid annuloplasty, the LVMV after mitral valve plasty, and the LAMV after left atrial plication was 44%, 41%, and 60%, respectively. (author)

Mikhail, Amanda; Kadem, Lyes; di Labbio, Giuseppe

2016-11-01

Among all of the known congenital heart defects, Tetralogy of Fallot (TOF) is the most common cyanotic defect, accounting for 5% of all detected defects. Approximately 1 in 2518 births will result with TOF, leading to about 1657 cases per year in the United States alone. All of those affected will need surgical repair in order to have a relatively normal life and longer life span. Unfortunately, pulmonary regurgitation (PR) has been observed to appear two to three decades after the initial operation in 50% of operated cases. PR results in abnormal flow patterns in the right ventricle, which are currently poorly understood. In this experimental study, several severities of pulmonary regurgitation were simulated on a newly developed right ventricle using a cardiovascular simulator. The interaction between the tricuspid valve inflow and the pulmonary regurgitation was investigated using Time-resolved particle image velocimetry (TR-PIV). PR resulted in a turbulent jet that disturbed the optimal filling of the RV. Energy losses and viscous shear stresses were observed to significantly increase with the severity of PR. This study can contribute towards a better understanding of the suboptimal performance in patients with repaired TOF.

Pulmonary hypertension (PHT) and the resulting right ventricle dysfunction are important risk factors in patients who undergo cardiac surgery. The treatment of PHT and right ventricle dysfunction should be focused on maintaining the correct right ventricle after load, improving right ventricle function and reducing the right ventricle pre-load and therefore reducing pulmonary vascular resistance by means of vasodilators. A combined therapy of vasodilators and medicines which have different mechanisms of action, is becoming an option for the treatment of PHT. We present a 65 year old woman that suffered from mitral regurgitation, aortic valve disease, tricuspid and ascending aortic dilation with 115mmHg of pulmonary artery pressure (by ultrasound evaluation). The patient was operated on of mitral, aortic valve and tricuspid plastia and proximal aortic artery plastia as well. Previosly to surgery the patient suffered right ventricle dysfunction and PHT and was treated with nitric oxide, intravenous sildenafil and levosimendan. Subsequent evolution was satisfactory, PHT being controlled, without arterial hypotension nor respiratory alterations.

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.

Functional mitral regurgitation (MR) is a common finding in dilated cardiomyopathy. Left ventricular (LV) reverse remodeling with LV size reduction and improvement in LV function is a well recognized phenomenon. We aimed to evaluate the impact of LV remodeling on the mechanism leading to functional MR. Among 188 patients with non-ischemic dilated cardiomyopathy, 10 patients significantly improved their LV function, reduced LV size and MR severity during follow-up (RRMR). A comparison was made between their baseline and follow-up echocardiographic examinations and to a matched-control group of patients who did not improve (no RRMR). LV and left atrium (LA) dimensions and volumes, LV mass (LVM), LV ejection fraction (LVEF) (Simpsons), sphericity index (SI), mitral valve tenting area (TA) coaptation distance (CD), effective regurgitant orifice (ERO), and regurgitant volume were calculated. Multivariable analysis was performed in order to evaluate which echocardiographic parameters related to MR improvement in reverse remodeling. LV and LA dimensions and volumes, LVM, SI, TA, CD, ERO and right ventricle, in the RRMR group significantly decreased at follow-up (p < 0.04 for all). When compared to no RRMR, despite a similar ERO (0.2 ± 0.05 vs. 0.2 ± 0.08, p = 0.13) and a larger regurgitant volume (38 ± 9 vs. 29 ± 8 mL, p = 0.05) and despite similar clinical characteristics and medical treatment we found significantly higher LVEF, smaller LV dimensions and volumes, smaller LVM and SI in the RRMR group (p < 0.05 for all). On multivariable analysis the SI was the sole predictor of RRMR (p = 0.04, OR = 0.76, CI 0.58-0.99). Reverse remodeling characterized by improvement in LV function, reduction in LV size and an associated reduction in MR severity is related to LV SI at baseline.

Diagnosis of tricuspid insufficiency by Doppler flowmetry in the inferior vena cava. A comparison with right ventricular angiography

Energy Technology Data Exchange (ETDEWEB)

Smith, H.J.

Eighty-five patients subjected to routine heart catheterization were examined with duplex scanning of the inferior vena cava. Adequate Doppler recordings and a right ventricular angiography were obtained in 79 of them. Tricuspid insufficiency was found to be present in 34 patients at angiography and in 24 at duplex examination. No false positive Doppler diagnoses of tricuspid insufficiency occurred. The possibility of false positive angiographic diagnoses is discussed. A high correlation was found between percentage reversed flow in the inferior vena cava during ventricular systole and degree of angiographic tricuspid insufficiency. It is concluded that duplex scanning of the inferior vena cava seems to be a good alternative to angiography in the diagnosis and quantification of tricuspid insufficiency.

1982-01-01

The clinical, haemodynamic and angiographic features of 18 patients with right ventricular endomyocardial fibrosis (RVEMF) and 8 patients with Ebstein's anomaly of the tricuspid valve (EATV) have been compared. Diagnosis was confirmed by selective angiography. The position of the tricuspid annulus was identified from selective right ventricular angiograms and confirmed by selective right coronary angiography. In 83% of RVEMF patients the tricuspid annulus was displaced to the left of the spine. A false impression of displacement of the tricuspid leaflet can thus be created. However, a tricuspid leaflet displaced away from the tricuspid annulus was found only in patients with EATV. A considerable overlap exists between the wide spectrum of clinical presentations of the two conditions. Helpful distinguishing features that favour EATV were, the presence of a scratchy diastolic murmur and polyphasic QRS complexes in the ECG. Atrial fibrillation in the ECG, and myocardial calcification or pericardial effusion, whenever present, favour RVEMF.

Data on the prevalence of valvular heart disease in very old individuals are scarce and based mostly on in-hospital series. In addition, the potential detrimental effect of valvular heart disease on the activities of daily living is unknown. The present study evaluated the prevalence of significant valvular heart disease and the impact of valvular heart disease on the activities of daily living in community dwelling nonagenarians. Nested within the Leiden 85-plus study, a population based follow-up study of the oldest old, a sample of 81 nonagenarians was recruited. The left ventricular (LV) dimensions, function and the presence and severity of heart valvular disease were evaluated by echocardiography. Significant valvular heart disease included any mitral or aortic stenosis severity, moderate or severe mitral regurgitation, moderate or severe aortic regurgitation and moderate or severe tricuspid regurgitation. Activities of daily living were assessed using the Groningen Activity Restriction Scale (GARS). LV cavity diameters (end-diastolic diameter 47 +/- 8 mm, end-systolic diameter 30 +/- 8 mm) and systolic LV function (LV ejection fraction 66 +/- 13%) were within normal for the majority of the participants. Significant valvular disease was present in 57 (70%) individuals, with mitral regurgitation and aortic regurgitation as the most frequent valve diseases (49% and 28% respectively). The GARS score between individuals with and without significant valvular heart disease was similar (36.2 +/- 9.2 vs. 34.4 +/- 13.2, p = 0.5). Nonagenarian, outpatient individuals have a high prevalence of significant valvular heart disease. However, no relation was observed between the presence of significant valvular heart disease and the ability to perform activities of daily living.

Despite the positive clinical results of valve-sparing aortic root replacement, little is known about the causes of reoperations and the modes of failure. From October 1999 to June 2010, 101 patients underwent valve-sparing aortic root replacement using the David reimplantation technique. The definition of aortic root repair failure included the following: (1) intraoperative conversion to the Bentall procedure; (2) reoperation performed because of aortic regurgitation; and (3) aortic regurgitation equal to or greater than a moderate degree at the follow-up. Sixteen patients were considered to have repair failure. Three patients required intraoperative conversion to valve replacement, 3 required reoperation within 3 months, and another 8 required reoperation during postoperative follow-up. At initial surgery 5 patients had moderate to severe aortic regurgitation, 6 patients had acute aortic dissections, 3 had Marfan syndrome, 2 had status post Ross operations, 3 had bicuspid aortic valves, and 1 had aortitis. Five patients had undergone cusp repair, including Arantius plication in 3 and plication at the commissure in 2. The causes of early failure in 6 patients included cusp perforation (3), cusp prolapse (3), and severe hemolysis (1). The causes of late failure in 10 patients included cusp prolapse (4), commissure dehiscence (3), torn cusp (2), and cusp retraction (1). Patients had valve replacements at a mean of 23 ± 20.9 months after reimplantation and survived. Causes of early failure after valve-sparing root replacement included technical failure, cusp lesions, and steep learning curve. Late failure was caused by aortic root wall degeneration due to gelatin-resorcin-formalin glue, cusp degeneration, or progression of cusp prolapse. Copyright © 2011 The Society of Thoracic Surgeons.

Full Text Available Abstract Introduction The main clinical manifestations of Whipple's disease are weight loss, arthropathy, diarrhea and abdominal pain. Cardiac involvement is frequently described. However, endocarditis is rare and is not usually the initial presentation of the disease. To the best of our knowledge, this is the first reported case of a patient with Tropheryma whipplei tricuspid endocarditis without any other valve involved and not presenting signs of arthralgia and abdominal involvement. Case presentation We report a case of a 50-year-old Caucasian man with tricuspid endocarditis caused by Tropheryma whipplei, showing signs of severe shock and an absence of other more classic clinical signs of Whipple's disease, such as arthralgia, abdominal pain and diarrhea. Tropheryma whipplei was documented by polymerase chain reaction of the blood and pleural fluid. The infection was treated with a combined treatment of doxycycline, hydroxychloroquine and sulfamethoxazole-trimethoprim for one year. Conclusion Tropheryma whipplei infectious endocarditis should always be considered when facing a blood-culture negative endocarditis particularly in right-sided valves. Although not standardized yet, treatment of Tropheryma whipplei endocarditis should probably include a bactericidal antibiotic (such as doxycycline and should be given over a prolonged period of time (a minimum of one year.

Acquired tricuspid valve stenosis (TVS) is a rare complication of endocardial pacing lead implantation in humans that has only been described once previously in the veterinary literature in a dog with excessive lead redundancy. A 12 yr old terrier presented with right-sided congestive heart failure 6 mo after implantation of a second ventricular endocardial pacing lead. The second lead was placed due to malfunction of the first lead, which demonstrated abnormally low impedance. Transthoracic echocardiography identified hyperechoic tissue associated with the pacing leads as they crossed the tricuspid valve annulus as well as a stenotic tricuspid inflow pattern via spectral Doppler interrogation. Medical management was ultimately unsuccessful and the dog was euthanized 6 wk after TVS was diagnosed. The authors report the first canine case of acquired TVS associated with two ventricular endocardial pacing leads.

Regurgitations in a Lamb with Acute Coenurosis-A case Report.

Full Text Available Coenurosis is a disease of the central nervous system in sheep, caused by Coenurus cerebralis, the larval stage of Multiceps multiceps, which inhabits the small intestine of Canidae. A case of regurgitations in a 2.5 month old lamb with acute coenurosis is being reported. The lamb was presented with a sudden onset of ataxia and regurgitations for 10 days. The post-mortem examination revealed 4 immature C. cerebralis cysts between 0.5 and 1.5 cm in diameter located in the brainstem and cerebellum, and histopathological examination revealed multifocal pyogranulomatous meningoencephalitis, so a diagnosis of acute coenurosis was established. Thus, acute coenurosis should be included in the differential diagnosis of regurgitations in lambs.

The ratio of left ventricular to right ventricular stroke counts measured by radionuclide angiography has been used in adults to estimate the severity of left-sided valvular regurgitation. The validation of this technique in children for assessment of right and left ventricular volume overload is reported herein. Radionuclide stroke count ratios in 60 children aged 0.5 to 19 years (mean 11) were determined. Based on their diagnoses, the patients were divided into 3 groups: (1) normal--40 patients with no shunts or valvular regurgitation, (2) left ventricular volume overload--13 patients with mitral or aortic regurgitation, or both, and (3) right ventricular volume overload--7 patients, 2 with severe tricuspid regurgitation, 3 with atrial septal defects, and 2 with total anomalous pulmonary venous drainage. The radionuclide stroke count ratio clearly differentiated these groups (p less than 0.05): normal patients had a stroke count ratio of 1.04 +/- 0.17 (mean +/- 1 standard deviation), the left ventricular volume overload group had a stroke count ratio of 2.43 +/- 0.86, and the right ventricular volume overload group had a stroke count ratio of 0.44 +/- 0.17. In 22 of our 60 patients, radionuclide stroke count ratios were compared with cineangiographic stroke volume ratios, resulting in a correlation coefficient of 0.88. It is concluded that radionuclide ventriculography is an excellent tool for qualitative and quantitative assessment of valvular regurgitation in children

Pacemaker lead fracture without an increase in lead impedance caused by cardiac fibroma

2013-12-01

Full Text Available We report the case of a 64-year-old man who had a permanent pacemaker with a unipolar silicone electrode positioned in the right ventricle in 1989 for sinus node dysfunction. On a routine checkup in June 2011, a 28-mm-diameter mass was discovered, which appeared to adhere to the tricuspid valve and the ventricular lead. The size of the mass did not change for the next 6 months, and the lead impedance was maintained at around 500–600 Ω. Because pacing failure was observed in January 2012, he underwent an urgent pacemaker check; however, the lead impedance was found not to have increased greatly (689 Ω. Nevertheless, the pacemaker lead was noted to be fractured at the tricuspid level. His echocardiogram showed new severe tricuspid regurgitation and a floating mass around the lead. We extracted the fractured lead, enucleated the tumor, replaced the tricuspid valve, and placed an epicardial lead. Macroscopic examination revealed that the tumor surrounded the fractured lead and covered the stump. Pathological examination revealed that the tumor was composed of fibrous connective tissue. We presumed that electric current continued to flow through the stump of the fractured unipolar lead to the generator, and this might have caused the limited increase in lead impedance.

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.

Background Patients with free pulmonary regurgitation or mixed pulmonary stenosis and regurgitation and severely dilated right ventricles (RV) show little improvement in ventricular function after pulmonary valve replacement when assessed by traditional echocardiographic markers. We evaluated changes in right and left ventricular (LV) function using speckle tracking echocardiography in patients after SAPIEN transcatheter pulmonary valve (TPV) placement. Methods Echocardiograms were evaluated at baseline, discharge, 1 and 6 months after TPV placement in 24 patients from 4 centers. Speckle tracking measures of function included peak longitudinal strain, strain rate, and early diastolic strain rate. RV fractional area change, tricuspid annular plane systolic excursion, and left ventricular LV ejection fraction were assessed. Routine Doppler and tissue Doppler velocities were measured. Results At baseline, all patients demonstrated moderate to severe pulmonary regurgitation; this improved following TPV placement. No significant changes were detected in conventional measures of RV or LV function at 6 months. RV longitudinal strain (−16.9% vs. −19.6%, P echocardiography may be more sensitive than traditional measures in detecting changes in systolic function after TPV implantation.

A 12 year-old intact male Pembroke Welsh corgi weighing 10.8 kg was presented for evaluation of a 3-month history of dyspnea, and a 1-week history of exercise intolerance and anorexia. Severe hypoxemia (PaO 2 56 mmHg), diffuse lung alveolar infiltration, and severe pulmonary hypertension (tricuspid regurgitation pressure gradient was 81 mmHg) were identified. A tentative diagnosis of severe PH due to lung disease or pulmonary thromboembolism was made and treated intensively. After 5 days of hospitalization, the dog died despite oxygen supplementation and anticoagulant therapy. This dog was diagnosed as unclassified interstitial lung disease based on histopathological findings.

This brief report presents a patient with isolated right heart failure and two rare underlying causes, hyperthyroidism and dysplastic tricuspid valve. Repair of the tricuspid valve and treatment of the hyperthyroidism were both essential for successful treatment of the right heart failure. Most important, recrudescence of hyperthyroidism in this patient was associated with reappearance of florid right heart failure. This report provides further information about a potential linkage of hyperthyroidism and severe right heart failure.

The effects of upright and supine position on cardiac response to exercise were assessed by radionuclide ventriculography in 15 patients with moderate to severe aortic regurgitation (AR) and in 10 control subjects. In patients with AR, heart rate was higher during upright exercise, but systolic and diastolic blood pressure and left ventricular (LV) output were similar during both forms of exercise. LV stroke volume and end-diastolic volume were not altered during supine exercise. LV end-systolic volume increased and ejection fraction decreased during supine exercise, but both were unchanged during upright exercise. Of 15 patients, 5 in the upright and 12 in the supine position had an abnormal LV ejection fraction response to exercise (p less than 0.01). Right ventricular ejection fraction increased and regurgitant index decreased with both forms of exercise and was not significantly different between the 2 positions. Thus, posture is important in determining LV response to exercise in patients with moderate to severe AR.

Exercise radionuclide angiography is being used to evaluate left ventricular function in patients with aortic regurgitation. Ejection fraction is the most common variable analyzed. To better understand the rest and exercise ejection fraction in this setting, 20 patients with asymptomatic or minimally symptomatic severe aortic regurgitation were studied. All underwent simultaneous supine exercise radionuclide angiography and pulmonary gas exchange measurement and underwent rest and exercise measurement of pulmonary artery wedge pressure (PAWP) during cardiac catheterization. Eight patients had a peak exercise PAWP less than 15 mm Hg (group 1) and 12 had a peak exercise PAWP greater than or equal to 15 mm Hg (group 2). Group 1 patients were younger and more were in New York Heart Association class I. The two groups had similar cardiothoracic ratios, changes in ejection fractions with exercise, and rest and exercise regurgitant indexes. Using multiple regression analysis, the best correlate of the exercise PAWP was peak oxygen uptake (r . -0.78, p less than 0.01). No other measurement added significantly to the regression. When peak oxygen uptake was excluded, rest and exercise ejection fraction also correlated significantly (r . -0.62 and r . -0.60, respectively, p less than 0.01). Patients with asymptomatic or minimally symptomatic severe aortic regurgitation have a wide spectrum of cardiac performance in terms of the PAWP during exercise. The absolute rest and exercise ejection fraction and the level of exercise achieved are noninvasive variables that correlate with exercise PAWP in aortic regurgitation, but the change in ejection fraction with exercise by itself is not

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 Objectives. Bicuspid aortic valve (AV represents the most common form of congenital AV malformation, which is frequently associated with pathologies of the ascending aorta. We compared the mechanical properties of the aortic wall between patients with bicuspid and tricuspid AV using a new custom-made device mimicking transversal aortic wall shear stress. Methods. Between 03/2010 and 07/2011, 190 consecutive patients undergoing open aortic valve replacement at our institution were prospectively enrolled, presenting either with a bicuspid (group 1, n=44 or a tricuspid (group 2, n=146 AV. Aortic wall specimen were examined with the “dissectometer” resulting in nine specific aortic-wall parameters derived from tensile strength curves (TSC. Results. Patients with a bicuspid AV showed significantly more calcified valves (43.2% versus 15.8%, P<0.001, and a significantly thinner aortic wall (2.04±0.42 mm versus 2.24±0.41 mm, P=0.008. Transesophageal echocardiography diameters (annulus, aortic sinuses, and sinotubular junction were significantly larger in the bicuspid group (P=0.003, P=0.02, P=0.01. We found no difference in the aortic wall cohesion between both groups as revealed by shear stress testing (P=0.72, P=0.40, P=0.41. Conclusion. We observed no differences of TSC in patients presenting with tricuspid or bicuspid AVs. These results may allow us to assume that the morphology of the AV and the pathology of the ascending aorta are independent.

Cardiac carcinoid: tricuspid delayed hyperenhancement on cardiac 64-slice multidetector CT and magnetic resonance imaging.

2012-02-01

INTRODUCTION: Carcinoid heart disease is a rare condition in adults. Its diagnosis can be easily missed in a patient presenting to a primary care setting. We revised the advantages of using coronary multidetector computed tomography (MDCT) and cardiac magnetic resonance imaging (MRI) in diagnosing this condition. MATERIALS AND METHODS: We studied a 65-year-old patient with carcinoid heart disease and right heart failure using transthoracic Doppler-echocardiogram, cardiac MDCT and MRI. Cardiac echocardiogram revealed marked thickening and retraction of the tricuspid leaflets with dilated right atrium and ventricle. Cardiac MDCT and MRI demonstrated fixation and retraction of the tricuspid leaflets with delayed contrast hyperenhancement of the tricuspid annulus. CONCLUSION: This case demonstrates fascinating imaging findings of cardiac carcinoid disease and highlights the increasing utility of contrast-enhanced MRI and cardiac MDCT in the diagnosis of this interesting condition.

Neonatal Marfan syndrome is a rare and severe phenotype of this disease. A poor prognosis is anticipated due to the high probability of congestive heart failure, and mitral and tricuspid regurgitations with suboptimal response to medical therapy and difficulties in surgical management at an early age. We present two consecutive patients with this disease who are the first reported cases from Iran to the best of our knowledge. Unfortunately both of them died shortly after diagnosis. Neonatal Marfan syndrome is reported from Iran and has a poor prognosis like the patients reported from elsewhere.

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.

In patients with mitral regurgitation (MR), changes in cardiac stroke volume, and thus renal preload and afterload may affect kidney function. Percutaneous mitral valve repair (PMVR) with the MitraClip® system can be a therapeutic alternative to surgical valve repair. The influence of MitraClip® therapy on renal function and clinical outcome parameters is unknown. Sixty patients with severe MR underwent PMVR using the MitraClip® system in an open-label observational study. Patients were stratified according to their renal function. All clips have been implanted successfully. Effective reduction of MR by 2-3 grades acutely improved KDOQI class. Lesser MR reduction (MR reduction of 0-1 grades) led to worsening of renal function in patients with pre-existing normal or mild (KDOQI 1-2) compared to severe (KDOQI 3-4) renal dysfunction. Reduction of MR was associated with improvement in Minnesota Living with Heart Failure Questionnaire (MLHFQ), NYHA-stadium, and 6-minute walk test. Successful PMVR was associated with an improvement in renal function. The improvement in renal function was associated with the extent of MR reduction and pre-existing kidney dysfunction. Our data emphasize the relevance of PVMR to stabilize the cardiorenal axis in patients with severe MR. © 2014 Wiley Periodicals, Inc.

Ebstein's anomaly is a rare complex congenital heart defect of the tricuspid valve. We aimed to describe the frequency, clinical profile, and early and short-term post-operative results in patients under the age of 18 years operated for this anomaly in a tertiary center in Angola. A retrospective cross-sectional study was conducted over a period of 37 months. We analyzed all patients diagnosed with congenital heart defects. Of the 1362 patients studied, eight (0.6%) had Ebstein's anomaly; six patients (75%) were female. Mean age was 69±59 months. Five patients were in NYHA functional class III or IV. Mean cardiothoracic index was 0.72. Seven patients (87.5%) had severe tricuspid regurgitation and five (62.5%) had another associated congenital heart defect. All patients were operated: two had complications and one (12.5%) died in the early post-operative period. The mean follow-up time was 1.22±0.6 years, and mortality during follow-up was 12.5% (n=1). At the end of the study, of the five patients in whom cone reconstruction was performed, four (80%) were in functional class I. Mean cardiothoracic index decreased to 0.64. Three patients had mild and two had moderate tricuspid regurgitation. The patient who underwent cone reconstruction and a Glenn procedure was in functional class I. The frequency of Ebstein's anomaly was similar to that in other centers. Cone reconstruction was viable in the majority of patients, with good early and short-term results.

2009-01-01

We retrospectively investigated the impact of bicuspid aortic valve on the prognosis of patients who had definite infective endocarditis of the native aortic valve.Of 51 patients, a bicuspid aortic valve was present in 22 (43%); the other 29 had tricuspid aortic valves. On average, the patients who had bicuspid valves were younger than those who had tricuspid valves. Patients with a tricuspid valve had larger left atrial diameters and were more likely to have severe mitral regurgitation.Periannular complications, which we detected in 19 patients (37%), were much more common in the patients who had a bicuspid valve (64% vs 17%, P = 0.001). The presence of a bicuspid valve was the only significant independent predictor of periannular complications. The in-hospital mortality rate in the bicuspid group was lower than that in the tricuspid group; however, this figure did not reach statistical significance (9% vs 24%, P = 0.15). In multivariate analysis, left atrial diameter was the only independent predictor associated with an increased risk of death (hazard ratio, 2.19; 95% confidence interval, 1.1-4.5; P = 0.031).In our study, patients with infective endocarditis in a bicuspid aortic valve were younger and had a higher incidence of periannular complications. Although a worse prognosis has been reported previously, we found that infective endocarditis in a native bicuspid aortic valve is not likely to increase the risk of death in comparison with infective endocarditis in native tricuspid aortic valves.

This study sought to evaluate if the presence of endocarditis was independently associated with increased perioperative blood transfusion in patients undergoing aortic valve replacements (AVR) with aortic regurgitation. This was a retrospective study. Large Canadian tertiary care hospital. Six hundred sixty-two consecutive patients with aortic regurgitation score of 3 or higher undergoing AVR from 1995 to 2012. No interventions were performed in this retrospective study. After REB approval, data were obtained from a center-specific database. Univariate analysis was performed to identify variables that may be associated with transfusion of any allogeneic blood product perioperatively. A multivariate logistic regression was generated to identify independent predictors of perioperative transfusion. Unadjusted transfusion rates in patients with no endocarditis and with endocarditis were 32% and 70% (p70, urgent/emergent surgery, BMIEndocarditis was not an independent predictor of transfusion (OR = 0.748; 95% CI = 0.35-1.601). In patients undergoing AVR, unadjusted perioperative transfusion rates were higher when endocarditis was present. However, after adjustment, aortic valve endocarditis was not independently associated with blood transfusion. The authors' observation could be explained by the higher prevalence of many independent predictors of transfusion, such as comorbidities or more complex surgery, within the endocarditis group. Thus, AV endocarditis, in the absence of other risk factors, was not associated with increased perioperative transfusion risk. Copyright © 2016 Elsevier Inc. All rights reserved.

Tricuspid annuloplasty is increasingly performed during left heart valve surgery, but the long-term clinical outcome postoperatively is not satisfactory. The aim of this study was to determine whether residual pulmonary hypertension (PHT) contributes to the adverse outcome. One-hundred thirty-seven patients (age 61±11 years; men, 30%) who underwent tricuspid annuloplasty during left-side valve surgery were enrolled. The mean pulmonary artery systolic pressure before surgery was 49±13 mm Hg and 32±15 mm Hg following surgery. Patients were divided into 3 groups according to postoperative pulmonary artery systolic pressure: no residual PHT (n=78, 57%), mild residual PHT (n=43, 31%), or significant residual PHT (n=16, 12%). A preoperative larger right ventricular (RV) geometry and tricuspid valve tethering area were associated with mild or significant residual PHT. A total of 24 adverse events (20 heart failures and 4 cardiovascular deaths) occurred during a median follow-up of 25 months. Kaplan-Meier survival curve demonstrated that patients with significant residual PHT had the highest percentage of adverse events followed by those with mild residual PHT. Patients with no residual PHT had a very low risk of adverse events. Multivariable Cox regression analysis revealed that both mild (hazard ratio=4.94; 95% CI =1.34-18.16; P=0.02) and significant residual PHT (hazard ratio=8.67; 95% CI =2.43-30.98; P<0.01) were independent factors associated with adverse events. The present study demonstrated that 43% of patients who underwent tricuspid annuloplasty had residual PHT. The presence of mild or significant residual PHT was associated with adverse events in these patients. © 2016 The Authors.

Percutaneous interventional mitral regurgitation treatment using the Mitra-Clip system

DEFF Research Database (Denmark)

Boekstegers, P; Hausleiter, J; Baldus, S

2014-01-01

The interventional treatment of mitral valve regurgitation by the MitraClip procedure has grown rapidly in Germany and Europe during the past years. The MitraClip procedure has the potential to treat high-risk patients with secondary mitral valve regurgitation and poor left ventricular function....... Furthermore, patients with primary mitral valve regurgitation may be treated successfully by the MitraClip procedure in case of high surgical risk or in very old patients. At the same time it has been emphasised that the MitraClip interventional treatment is still at an early stage of clinical development....... The largest clinical experience with the MitraClip procedure so far is probably present in some German cardiovascular centers, which here summarise their recommendations on the current indications and procedural steps of the MitraClip treatment. These recommendations of the AGIK and ALKK may present a basis...

Pulmonary regurgitation is a common finding in patients after correction of tetralogy of Fallot (TOF). Right ventricular impairment and even ventricular arrhythmia have been ascribed to pulmonary valve insufficiency (PI), which is therefore an important issue in follow-up examinations. To compare PI measured by echocardiography (ECHO) with data provided by cardiac MRI (CMR). We studied 54 selected patients (18 female; median age 14.0 years, range 3.8-53.4 years) after surgical correction of TOF. To quantify pulmonary regurgitant fraction (PRF) by CMR, flow velocity mapping was performed. On Doppler ECHO, length, width and localization of regurgitant flow was measured. The severity of PI was categorized as mild, moderate or severe and compared to the data obtained by CMR. On CMR the mean PRF was 29.2 {+-} 13.4%. Patients with a transannular patch had a significantly higher PRF (39.9 {+-} 11.6%) than patients with an intact annular ring (23.6 {+-} 11.4%). Differentiation by Doppler ECHO between the categories mild, moderate and severe PI was confirmed by significant differences in PRF measured by CMR (mild vs. moderate P < 0.04; moderate vs. severe P < 0.014; mild vs. severe P < 0.001). Furthermore, PRF correlated with right ventricular end diastolic volume index (r = 0.45, P < 0.01) and right ventricular end systolic volume index (r = 0.39, P < 0.01). Doppler ECHO can estimate the severity of PI after repair of TOF with acceptable results compared to CMR flow measurement. In univariate analysis there is only a weak influence of PRF on right ventricular volume. (orig.)

Cardiac complications are among the most serious problems of thalassemia intermedia patients. The current study was initiated to address the latter issue through the study of the echocardiographic findings and correlate it with clinical characteristics of thalassemia intermedia patients in Duhok, Kurdistan region, Iraq. An echocardiographic assessment of 61 beta-thalassemia intermedia cases was performed. It included 30 males and 31 females, with a mean age 19.6 ± 7.5 years. The standard echostudy of two-dimension and M-mode measurements of cardiac chambers were done. The continuous doppler regurgitant jet of tricuspid and pulmonary valves were recorded. Left ventricle diastolic function was assessed by pulsed doppler of mitral valve inflow. To correlate the clinical with echocardiographic findings, patients were divided, according to tricuspid regurgitant velocity, into three groups (intermedia patients. Therapeutic trails targeting these complications are indicated, and echocardiographic assessment is necessary to be offered early for thalassemia intermedia.

Full Text Available Introduction: Ebstein's anomaly (EA is a rare congenital malformation of the tricuspid valve, often associated with PFO, which is present in 80-90% of patients & predisposes to para-doxical embolization. Case Report: The case described was a 30 year old female, in the post partum phase, (ten days after normal vaginal delivery who was presented to the emergency department with seizure & Rt sided hemiplegia & aphasia. On brain computed tomography scan there was large in-farct of Lt sided hemisphere in fronto temporopartial, and her brain MRI subsequently con-firmed the infarct. Laboratory tests including coagulation study & infectious tests were nor-mal. But electrocardiogram showed AG block grade I. Trans thoracic and Trans esophageal echocardiography revealed Ebstein's anomaly. Dynamic cardiac MRI showed severe tricus-pid regurgitation due to sown ward displacement of tricuspid valve to apical heart associated with patent foramen oral & ASD (Ejection fraction of right chamber was normal and no evi-dence of clot. Conclusion: After ruling out the other diagnoses, paradoxical emboli was considered as the cause leading to the stroke in this case. (Sci J Hamadan Univ Med Sci 2014; 21 (1:72-75

Babu-Narayan Sonya V

2009-01-01

Full Text Available Abstract Background Pulmonary regurgitation is a common and clinically important residual lesion after repair of tetralogy of Fallot. Cardiovascular magnetic resonance (CMR phase contrast velocity mapping is widely used for measurement of pulmonary regurgitant fraction. Breath-hold acquisitions, usually acquired during held expiration, are more convenient than the non-breath-hold approach, but we hypothesized that breath-holding might affect the amount of pulmonary regurgitation. Methods Forty-three adult patients with a previous repair of tetralogy of Fallot and residual pulmonary regurgitation were investigated with CMR. In each, pulmonary regurgitant fraction was measured from velocity maps transecting the pulmonary trunk, acquired during held expiration, held inspiration, by non-breath-hold acquisition, and also from the difference of right and left ventricular stroke volume measurements. Results Pulmonary regurgitant fraction was lower when measured by velocity mapping in held expiration compared with held inspiration, non-breath-hold or stroke volume difference (30.8 vs. 37.0, 35.6, 35.4%, p = 0.00017, 0.0035, 0.026. The regurgitant volume was lower in held expiration than in held inspiration (41.9 vs. 48.3, p = 0.0018. Pulmonary forward flow volume was larger during held expiration than during non-breath-hold (132 vs. 124 ml, p = 0.0024. Conclusion Pulmonary regurgitant fraction was significantly lower in held expiration compared with held inspiration, free breathing and stroke volume difference. Altered airway pressure could be a contributory factor. This information is relevant if breath-hold acquisition is to be substituted for non-breath-hold in the investigation of patients with a view to re-intervention.

Left ventricular remodeling in preclinical experimental mitral regurgitation of dogs.

Dogs with experimental mitral regurgitation (MR) provide insights into the left ventricular remodeling in preclinical MR. The early preclinical left ventricular (LV) changes after mitral regurgitation represent progressive dysfunctional remodeling, in that no compensatory response returns the functional stroke volume (SV) to normal even as total SV increases. The gradual disease progression leads to mitral annulus stretch and enlargement of the regurgitant orifice, further increasing the regurgitant volume. Remodeling with loss of collagen weave and extracellular matrix (ECM) is accompanied by stretching and hypertrophy of the cross-sectional area and length of the cardiomyocyte. Isolated ventricular cardiomyocytes demonstrate dysfunction based on decreased cell shortening and reduced intracellular calcium transients before chamber enlargement or decreases in contractility in the whole heart can be clinically appreciated. The genetic response to increased end-diastolic pressure is down-regulation of genes associated with support of the collagen and ECM and up-regulation of genes associated with matrix remodeling. Experiments have not demonstrated any beneficial effects on remodeling from treatments that decrease afterload via blocking the renin-angiotensin system (RAS). Beta-1 receptor blockade and chymase inhibition have altered the progression of the LV remodeling and have supported cardiomyocyte function. The geometry of the LV during the remodeling provides insight into the importance of regional differences in responses to wall stress. Copyright © 2012 Elsevier B.V. All rights reserved.

Clinical application of radionuclide cardiac study to the right heart diseases

We experienced the four cases of rare right heart diseases: those are two-chambered right ventricle, ball thrombus in right ventricle, right ventricular hypertrophy and tricuspid valve regurgitation due to multiple pulmonary infarction, and right ventricular and right atrial infarction. The preoperative or ante mortem diagnosis of these diseases is difficult, especially by use of a noninvasive technique. This report shows the usefulness of radionuclide cardiac study for diagnosis of these cases. In the two-chambered right ventricle, abnormal muscle bundle was visualized by 201 Tlcl and was observed as the filling defect by sup(99m)Tc-HSA radionuclide angiography. The ball thrombus showed the filling defect of sup(99m)Tc-HSA in the right ventricle but was not extracted by 201 Tlcl in the site of the defect area. In the multiple pulmonary infarction, the right ventricular free wall was visualized by 201 Tlcl, and during right ventricular systole, regurgitation from right atrium to inferior vena cava was noticed by means of sup(99m)Tc-HSA radionuclide angiography. These findings suggested right ventricular hypertrophy and tricuspid valve regurgitation. In the right ventricular and right atrial infarction, right ventricular ejection fraction and right atrial fractional emptying were lower than those of normal controls. (author)

Dextro-transposition of the great arteries (d-TGA) patients is at high risk of developing right ventricular dysfunction and tricuspid regurgitation in adulthood. Determining the relation between echocardiographic parameters, N-terminal pro-brain natriuretic peptide (NT-pro-BNP) levels and the New York Heart Association (NYHA) functional class may help determining the best time to operate them. Patients with simple d-TGA operated in infancy with an atrial switch procedure (Mustard or Senning operation) were followed up in our Adult Congenital Heart Disease Unit. Analytical, echocardiographic, and clinical parameters were determined to evaluate the correlation between right echocardiographic ventricular function, NT-pro-BNP levels, and NYHA functional class. Twenty-four patients with d-TGA were operated in infancy of whom 17 alive patients had simple d-TGA. Nine patients had NT-pro-BNP levels lower than 200 pg/mL and eight patients were above 200 pg/mL. Patients with lower hemoglobin concentration, higher right ventricular diameter or under diuretic treatment showed significant higher NT-pro-BNP levels (above 200 pg/dL). The Spearman test showed a positive correlation between basal right ventricular diameter and tricuspid regurgitation with pro NT BNP levels (correlation coefficient of .624; P=.017 and .490; P=.046, respectively) and a negative correlation with the right ventricle fractional area change (-.508, P=.045). No correlation was seen between NT-pro-BNP levels and the rest of echocardiographic parameters or the NYHA functional class. NT-pro-BNP levels showed a positive correlation with basal right ventricular diameter and tricuspid regurgitation but not with NYHA association functional class in d-TGA patients. © 2017, Wiley Periodicals, Inc.

2015-01-01

A best evidence topic in adult valvular surgery was written according to a structured protocol. The question addressed was 'Does concomitant tricuspid annuloplasty increase the perioperative mortality and morbidity when correcting left-sided valve disease?' A total of 561 papers were found using the reported search, of which 12 presented the best evidence to answer the clinical question. The authors, country, journal, date of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Among these 12 papers, there were nine retrospective studies, two cohort studies and one randomized controlled trial (RCT). Overall, additional tricuspid valve (TV) repair takes more time during operations, particularly with a ring annuloplasty method. The mean aortic cross-clamping times were 57-83 min without associated tricuspid repair and 62-100 min with, and cardiopulmonary bypass times without and with repair were 82-124 and 90-174 min, respectively. A study of 624 patients who had undergone isolated mitral valve (MV) surgery and MV surgery plus TV repair showed more female and atrial fibrillation patients in the tricuspid valve plasty (TVP) group, but no increase in the 30-day mortality was found. One RCT, presenting similar patient baseline characteristics, also found no difference in the hospital mortality rates between the TVP group and the non-TVP group. Another 10 studies also demonstrated no statistically significant differences in perioperative mortality. In a cohort study of 311 patients undergoing MV repair with or without tricuspid annuloplasty, postoperative complications, such as bleeding, stroke, pacemaker, haemofiltration and myocardial infarction, all showed no statistically significant differences in the two groups. One study retrospectively analysed a large number of patients undergoing either isolated left-sided valve surgery or a concomitant TV repair, and there were no statistically significant differences

Mitral valve perforation is an uncommon but important complication of infective endocarditis. We report a case of a 65-year-old man who was diagnosed to have infective endocarditis of his mitral valve. Through the course of his admission he had a rapid development of hemodynamic instability and pulmonary edema secondary to acutely worsening mitral regurgitation. While the TEE demonstrated an increase in the size of his bacterial vegetation, Real Time 3D TEE was ultimately the imaging modality through which the valve perforation was identified. Through this case report we discuss the advantages that RT-3D TEE has over traditional 2D TEE in the management of valve perforation.

Left ventricular performance was determined in 42 patients with moderate or severe aortic regurgitation during upright exercise by measuring left ventricular ejection fraction and volume with radionuclide ventriculography. Classification of the patients according to exercise tolerance showed that patients with normal exercise tolerance (greater than or equal to 7.0 minutes) had a significantly higher ejection fraction at rest (probability [p] . 0.02) and during exercise (p . 0.0002), higher cardiac index at exercise (p . 0.0008) and lower exercise end-systolic volume (p . 0.01) than did patients with limited exercise tolerance. Similar significant differences were noted in younger patients compared with older patients in ejection fraction at rest and exercise (both p . 0.001) and cardiac index at rest (p . 0.03) and exercise (p . 0.0005). The end-diastolic volume decreased during exercise in 60% of the patients. The patients with a decrease in volume were significantly younger and had better exercise tolerance and a larger end-diastolic volume at rest than did patients who showed an increase in volume. The mean corrected left ventricular end-diastolic radius/wall thickness ratio was significantly greater in patients with abnormal than in those with normal exercise reserve (mean +/- standard deviation 476 +/- 146 versus 377 +/- 92 mm Hg, p less than 0.05). Thus, in patients with chronic aortic regurgitation: 1) left ventricular systolic function during exercise was related to age, exercise tolerance and corrected left ventricular end-diastolic radius/wall thickness ratio, and 2) the end-diastolic volume decreased during exercise, especially in younger patients and patients with normal exercise tolerance or a large volume at rest

Full Text Available Implantation of a transvenous endocardial pacing lead in the right ventricle is contra-indicated after mechanical tricuspid valve replacement; therefore a surgical approach to the epicardium is usually required. This case report describes ventricular pacing via a branch of the coronary sinus in a patient with mechanical mitral, aortic and tricuspid valve replacements. In conclusion, this approach is minimally invasive, provides effective ventricular stimulation with low pacing threshold and stable lead position, and is a feasible option when transvenous right ventricular pacing is not possible.

Purpose The study compares the feasibility of the quantitative volumetric and semi-quantitative approach for quantification of chronic aortic regurgitation (AR) using different imaging modalities. Methods Left ventricular (LV) volumes, regurgitant volumes (RVol) and regurgitant fractions (RF) were assessed retrospectively by 2D, 3D echocardiography and cMRI in 55 chronic AR patients. Semi-quantitative parameters were assessed by 2D echocardiography. Results 22 (40%) patients had mild, 25 (46%) moderate and 8 (14%) severe AR. The quantitative volumetric approach was feasible using 2D, 3D echocardiography and cMRI, whereas the feasibility of semi-quantitative parameters varied considerably. LV volume (LVEDV, LVESV, SVtot) analyses showed good correlations between the different imaging modalities, although significantly increased LV volumes were assessed by cMRI. RVol was significantly different between 2D/3D echocardiography and 2D echocardiography/cMRI but was not significantly different between 3D echocardiography/cMRI. RF was not statistically different between 2D echocardiography/cMRI and 3D echocardiography/cMRI showing poor correlations (r echocardiography and 2D echocardiography/cMRI and good agreement was observed between 3D echocardiography/cMRI. Conclusion Semi-quantitative parameters are difficult to determine by 2D echocardiography in clinical routine. The quantitative volumetric RF assessment seems to be feasible and can be discussed as an alternative approach in chronic AR. However, RVol and RF did not correlate well between the different imaging modalities. The best agreement for grading of AR severity by RF was observed between 3D echocardiography and cMRI. LV volumes can be verified by different approaches and different imaging modalities. PMID:29519957

For the clinical assessment of patients with dyspnea, the inversion of the early (E) and late (A) transmitral flow during Valsalva maneuver (VM) frequently helps to distinguish pseudonormal from normal filling pattern. However, in an important number of patients, VM fails to reveal the change from dominant early mitral flow velocity toward larger late velocity. From December 2009 to October 2010, we selected consecutive patients with abnormal filling with (n=25) and without E/A inversion (n=25) during VM. Transmitral, tricuspid, and pulmonary Doppler traces were recorded and the degree of insufficiency was estimated. After evaluating all standard echocardiographic morphological, functional, and flow-related parameters, it became evident that the failure to unmask the pseudonormal filling pattern by VM was related to the degree of the tricuspid insufficiency (TI). TI was graded as mild in 24 of 25 patients in the group with E/A inversion during VM, whereas TI was graded as moderate to severe in 24 of the 25 patients with pseudonormal diastolic function without E/A inversion during VM. Our data suggest that TI is a major factor to prevent E/A inversion during a VM in patients with pseudonormal diastolic function. This probably is due to a decrease in TI resulting in an increase in forward flow rather than the expected decrease during the VM. Thus, whenever a pseudonormal diastolic filling pattern is suspected, the use of a VM is not an informative discriminator in the presence of moderate or severe TI.

Acute peritonitis as the first presentation of valvular cardiomyopathy.

Valvular cardiomyopathy can present a diagnostic challenge in the absence of overt cardiac symptoms. This report describes the case of a 46-year-old woman who presented with acute peritonitis associated with vomiting and abdominal distension. Subsequent abdominal computed tomography and ultrasound revealed bibasal pleural effusions, ascites, and normal ovaries. An echocardiogram revealed that all cardiac chambers were dilated with a global decrease in contractility and severe mitral, tricuspid, and aortic regurgitation. A diagnosis of cardiomyopathy with acute heart failure, secondary to valvular heart disease, was secured. Acute peritonitis as the presenting feature of valvular cardiomyopathy is a rare clinical entity.

Surgical treatment of infective and prosthetic endocarditis using allografts gives good results. Aortic allograft implantation is a common technique, while tricuspid valve replacement with a mitral allograft is very rare. Multiple valve disease in case of infective endocarditis is a surgical challenge as such patients are usually in a grave condition and results of surgical treatment are often unsatisfactory. In this article we describe a clinical case of successful surgical treatment in a patient with active infective endocarditis of aortic and tricuspid valve, complicated by an aortic-right ventricular fistula. The aortic valve and ascending aorta were replaced with a cryopreserved aortic allograft; the tricuspid valve was replaced with a cryopreserved mitral allograft. © The Author 2015.

Although implicitly accepted by many that the durability of valve-sparing aortic root replacement in patients with bicuspid aortic valve disease and connective tissue disorders will be inferior, this hypothesis has not been rigorously investigated. From 1993 to 2009, 233 patients (27% bicuspid aortic valve, 40% Marfan syndrome) underwent Tirone David valve-sparing aortic root replacement. Follow-up averaged 4.7 ± 3.3 years (1102 patient-years). Freedom from adverse outcomes was determined using log-rank calculations. Survival at 5 and 10 years was 98.7% ± 0.7% and 93.5% ± 5.1%, respectively. Freedom from reoperation (all causes) on the aortic root was 92.2% ± 3.6% at 10 years; 3 reoperations were aortic valve replacement owing to structural valve deterioration. Freedom from structural valve deterioration at 10 years was 96.1% ± 2.1%. No significant differences were found in survival (P = .805, P = .793, respectively), reoperation (P = .179, P = .973, respectively), structural valve deterioration (P = .639, P = .982, respectively), or any other functional or clinical endpoints when patients were stratified by valve type (tricuspid aortic valve vs bicuspid aortic valve) or associated connective tissue disorder. At the latest echocardiographic follow-up (95% complete), 202 patients (94.8%) had none or trace aortic regurgitation, 10 (4.7%) mild, 0 had moderate to severe, and 1 (0.5%) had severe aortic regurgitation. Freedom from greater than 2+ aortic regurgitation at 10 years was 95.3% ± 2.5%. Six patients sustained acute type B aortic dissection (freedom at 10 years, 90.4% ± 5.0%). Tirone David reimplantation valve-sparing aortic root replacement in carefully selected young patients was associated with excellent clinical and echocardiographic outcome in patients with either a tricuspid aortic valve or bicuspid aortic valve. No demonstrable adverse influence was found for Marfan syndrome or connective tissue disorder on durability, clinical outcome

1997-02-01

Certain foods and drinks such as alcohol, heavily spiced or fatty meals are known to provoke gastro-oesophageal reflux (GOR). This may give rise to symptoms of heartburn, epigastric pain and occasionally oral regurgitation of the gastric contents. Oral regurgitation of gastric juice is important in dentistry because of its association with dental erosion. This study measured oesophageal and oral reflux in 12 healthy subjects after a curry meal taken with alcohol 2 h before sleep. Each subject repeated the test with a bland non-reflux provoking control meal. GOR was measured by recording distal and proximal oesophageal pH on a dual channel, portable pH monitor. Oral pH was measured with a pH sensitive radio-telemetry capsule (RTC) held on the palate in a vacuum formed splint. Signals from the RTC were received by an aerial worn around the head. The pH change produced by GOR was estimated as the percentage time that pH (PTpH) was less than 4 in the distal oesophagus. Similarly, the PTpH was estimated reflux in only two subjects. In one of these subjects the bland meal provoked oral regurgitation with a PTpH < 5.5 of 13.5%. In the remaining subjects little oral regurgitation occurred.

Congestive heart failure results in an increase in systemic venous pressure that is transmitted to the inferior vena cava and to the hepatic veins. This can cause GI vascular and mucosal congestion. The aim of this study was to define upper-GI mucosal changes in patients with congestive heart failure. A total of 57 patients with congestive heart failure presenting with GI symptoms underwent upper endoscopy. Echocardiography was performed in all patients to determine the ejection fraction and the degree of tricuspid regurgitation. Transabdominal US was performed to measure the diameters of the hepatic veins, the inferior vena cava, and the portal vein. The presence and the severity of gastropathy and duodenopathy were compared with the parameters relating to severity of cardiac failure. Of the 57 patients studied, gastric mucosal changes were observed in 50 (88%), duodenal mucosal changes in 31 (54%), and esophageal mucosal changes in none. Gastric mucosal changes were the following: mosaic-like pattern (n = 50), punctate spots (n = 34), thickened folds (n = 5), watermelon stomach (n = 3), and telangiectasia (n = 10). Duodenal mucosal changes were the following: mosaic-like pattern (n = 29), thickened folds (n = 8), and telangiectasia (n = 2). Upper-GI symptoms were associated with gastropathy ( p = 0.027) and duodenopathy ( p = 0.003). The presence and the severity of duodenopathy showed a high degree of positive correlation with the presence and the severity of gastropathy (gamma value 0.690; p value <0.001). Patients with gastropathy and duodenopathy had higher mean inferior vena cava and hepatic vein diameters than those without gastropathy and duodenopathy. The severity of duodenopathy but not that of gastropathy was significantly associated with increasing severity of tricuspid regurgitation ( p = 0.001), larger portal vein diameter ( p = 0.02), and lower ejection fraction ( p = 0.008). Among patients with congestive cardiac failure with GI symptoms, changes

The morphological characteristics of artifacts from five species of necrophagous flies were examined following feeding on several types of diets. Four types of insect stains were produced by each species: regurgitate, defecatory, translocation, and tarsal tracks. Regurgitate was the most frequent type deposited (70.9 ± 2.4%), followed by defecatory (19.8 ± 4.0%), tarsal tracks (8.6 ± 1.2%), and translocation (0.7 ± 0.1%). Artifact shapes, sizes, and color were highly variable and species and diet specific. Calliphora vicina and Sarcophaga bullata consistently deposited the largest artifacts after feeding, whereas Chrysomya rufifacies and Ch. megacephala produced more tarsal tracks than the other species examined. Artifacts with tails were infrequently observed (4.1 ± 0.6% of all stains) but occurred as either defecatory or regurgitate stains. The widely variable morphologies of all types of fly artifacts underscores the view that insect stains cannot be distinguished from human bloodstains based on morphology alone. © 2017 American Academy of Forensic Sciences.

Dilated cardiomyopathy can lead to a variety of complications recognisable on clinical, echocardiographic, electrocardiographic and radiographic assessment. Among this, transthoracic echocardiography has the dual advantage of being helpful in making the diagnosis of dilated cardiomyopathy as well as an effective tool in early recognition of certain complications for timely management to improve the quality of life of these patients. Methods: This descriptive (case series) study was undertaken at departments of medicine, cardiology, paediatrics and obs/gyn, Ayub Teaching Hospital, Abbottabad from July to December, 2008. fifty patients of dilated cardiomyopathy without age and gender discrimination were selected by convenience sampling. Those with hypertrophic and restrictive cardiomyopathies, valvular and congenital heart disease, hypertension and ischemic heart disease were excluded. Results: mean age was 47.12 +- 17.9 year with male predominance (males=34, females=16). Mean ejection fraction was 30.6 +- 6.9%. complications revealed on echocardiography were intracardiac thrombi (5, 10%), spontaneous echo contrast (5, 10%), pericardial effusion (6, 12%), mitral regurgitation (46, 92%), tricuspid (25, 50%), aortic (5, 10%), pulmonary (2, 4%) multi-valvular regurgitation (28, 56%), and left atrial dilatation (36, 72%). Conclusion: lv systolic dysfunction, cardiac thrombi, spontaneous echo contrast, mitral and tricuspid regurgitation and left atrial enlargement are important complications of dilated cardiomyopathy. echocardiography is important tool towards identification of these complications.

This study investigated whether the timing of mitral valve (MV) repair or surgical approach affects outcomes in patients with MV regurgitation. Between 1992 and 2009, 2,255 patients underwent MV operations, including 1,305 with isolated MV regurgitation operations (1,054 repairs, 251 replacements). Surgical approaches were sternotomy in 377, video-assisted right minithoracotomy in 481, or robot-assisted in 447. Mean follow-up was 6.4±4.5 years (maximum, 19 years). Sternotomy MV repairs decreased during the study while minimally invasive MV repairs increased. Robotic MV repair patients were younger, with fewer women, had better left ventricular ejection fractions, and were more likely to have myxomatous degeneration (all p<0.001). The robotic approach led to a higher MV repair rate and increased use of leaflet/chordal procedures but had longer cardiopulmonary bypass and aortic cross-clamp times (all p<0.001). The 30-day mortality for isolated MV repair was similar for all approaches (p=0.409). Fewer neurological events were observed in the videoscopic and robotic groups (p=0.013). Adjusted survival was similar for all approaches (p=0.357). Survival in patients in New York Heart Association class I to II with myxomatous degeneration or annular dilatation was similar to a matched population but was worse for patients in class III to IV or undergoing MV replacement. MV repair in patients with severe MV regurgitation should be performed before New York Heart Association class III to IV symptoms develop. Minimally invasive MV repair techniques render similar outcomes as the sternotomy approach. Copyright © 2012 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

Early results after aortic valve-sparing root reconstruction are excellent. Longer-term follow-up, especially with regard to aortic valve function, is required for further judgment of these techniques. Between July of 1993 and September of 2006, 108 consecutive patients (mean age 53.0 +/- 15.8 years) underwent the Yacoub operation (group Y) and 83 patients underwent the David operation (group D). Innovative multilevel hierarchic modeling methods were used to analyze aortic regurgitation over time. In general, aortic regurgitation increased with time in both groups. Factors associated with the development of a significant increase in aortic regurgitation were Marfan syndrome, concomitant cusp intervention, and preoperative aortic anulus dimension. In Marfan syndrome, the initial aortic regurgitation was higher in group Y versus group D (0.56 aortic regurgitation vs 0.29 aortic regurgitation, P = .049), whereas the mean annual progression rate of aortic regurgitation was marginally higher in group Y (0.132 aortic regurgitation vs 0.075 aortic regurgitation, P = .1). Concomitant cusp intervention was associated with a significant aortic regurgitation increase in both groups (P Marfan syndrome and a large preoperative aortic annulus diameter were better treated with the reimplantation technique, whereas those with a smaller diameter were better treated with the remodeling technique. Concomitant free-edge plication of prolapsing cusps was disadvantageous in both groups. Considering these factors may serve to improve the aortic valve longevity after valve-sparing aortic root surgery.

Good quality of life correlates with a good exercise capacity in daily life in patients with tetralogy of Fallot (ToF). Patients after correction of ToF usually develop residual defects such as pulmonary regurgitation or stenosis of variable severity. However, the importance of different hemodynamic parameters and their impact on exercise capacity is unclear. We investigated several hemodynamic parameters measured by cardiovascular magnetic resonance (CMR) and echocardiography and evaluated which parameter has the most pronounced effect on maximal exercise capacity determined by cardiopulmonary exercise testing (CPET). 132 patients with ToF-like hemodynamics were tested during routine follow-up with CMR, echocardiography and CPET. Right and left ventricular volume data, ventricular ejection fraction and pulmonary regurgitation were evaluated by CMR. Echocardiographic pressure gradients in the right ventricular outflow tract and through the tricuspid valve were measured. All data were classified and correlated with the results of CPET evaluations of these patients. The analysis was performed using the Random Forest model. In this way, we calculated the importance of the different hemodynamic variables related to the maximal oxygen uptake in CPET (VO 2 %predicted). Right ventricular pressure showed the most important influence on maximal oxygen uptake, whereas pulmonary regurgitation and right ventricular enddiastolic volume were not important hemodynamic variables to predict maximal oxygen uptake in CPET. Maximal exercise capacity was only very weakly influenced by right ventricular enddiastolic volume and not at all by pulmonary regurgitation in patients with ToF. The variable with the most pronounced influence was the right ventricular pressure.

Mitral regurgitation (MR) is an important complication after prosthetic mitral valve (PMV) implantation. Transthoracic echocardiography is widely used to screen for native MR, but can be limited with PMV. Cine-cardiac magnetic resonance (CMR) holds the potential for the non-invasive assessment of regurgitant severity based on MR-induced inter-voxel dephasing. The study aim was to evaluate routine cine-CMR for the visual assessment of PMV-associated MR. Routine cine-CMR was performed at nine sites. A uniform protocol was used to grade MR based on jet size in relation to the left atrium (mild 2/3). MR was graded in each long-axis orientation, with overall severity based on cumulative grade. Cine-CMR was also scored for MR density and pulmonary vein systolic flow reversal (PVSFR). Visual interpretation was compared to quantitative analysis in a single-center (derivation) cohort, and to transesophageal echocardiography (TEE) in a multicenter (validation) cohort. The population comprised 85 PMV patients (59% mechanical valves, 41% bioprostheses). Among the derivation cohort (n = 25), quantitative indices paralleled visual scores, with stepwise increases in jet size and density in relation to visually graded MR severity (both p = 0.001). Patients with severe MR had an almost three-fold increase in quantitative jet area (p = 0.002), and a two-fold increase in density (p = 0.04) than did other patients. Among the multicenter cohort, cine-CMR and TEE (Δ =. 2 ± 3 days) demonstrated moderate agreement (κ = 0.44); 64% of discordances differed by ≤ 1 grade (Δ = 1.2 ± 0.5). Using a TEE reference, cine-CMR yielded excellent diagnostic performance for severe MR (sensitivity, negative predictive value = 100%). Patients with visually graded severe MR also had more frequent PVSFR (p cine-CMR. Cine-CMR is useful for the assessment of PMV-associated MR, which manifests concordant quantitative and qualitative changes in size and density of inter-voxel dephasing. Visual MR

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.

ão afeta a competência da valva tricúspide nem aumenta a incidência de comunicação interventricular residual ou bloqueio atrioventricular.Although the tricuspid valve and its attachments can sometimes obscure the margins of the ventricular septal defect from the vision of the surgeon, concern for valvular competence has made surgeons hesitate to take down the tricuspid valve. In this paper, the records of 34 patients divided into two groups (comparable by gender, age and associated anomalies were reviewed retrospectively. Treatment of the ventricular septal defect was done without (Group I, with 19 patients and with (Group II, with 15 patients takedown of the tricuspid valve to determine the degree of the tricuspid regurgitation and also the incidence of residual ventricular septal defects and atrioventricular block. The anterior and septal leaflets of the valve were taken down at the annulus and resuspended after VSD repair with running 6-0 polypropylene sutures. The degree of valvular regurgitation and the presence of residual VSD were determined by echo done on post-operative day one and at the the patient's discharge. Valvular regurgitation was graded as none in 12 patients of the Group I and in 10 patients of the Group II; trivial regurgitation in 5 patients of Group I and 4 of Group II; mild to moderate regurgitation in 2 cases of Group I and 1 in Group II. No patient had severe regurgitation. Even with a small number of cases, there was no statistically significant difference between the groups. There was only one case of residual VSD in Group I with spontaneous closure. The mortality in Group I was 10.5% and 6.6% in Group II. The authors conclude that takedown and re-suspension of the tricuspid valve in VSD repair surgery does not adversely affect valve competence neither increases the incidence of residual VSD or the incidence of A-V block.

Full Text Available Ebstein's anomaly is an uncommon congenital heart defect, with a prevalence of 0.3-0.5%. Its association with an imperforate tricuspid valve is an even more rare situation (less than 10% of cases. Prenatal diagnosis of this association by means of fetal echocardiography has not been reported. We describe here this association diagnosed before birth and confirmed after birth. The diagnostic potential and importance of fetal echocardiography during prenatal evaluation of cardiac malformations allows for adequate perinatal planning and management, with an obvious impact on morbidity and mortality.

Symptomatic mitral regurgitation has an unfavorable prognosis unless treated by surgery. However, the European registry of valvular heart disease reports that 49% of patients with this condition do not undergo surgery. Percutaneous treatment of mitral regurgitation with MitraClip® has been proved a safe, efficient adjunct to medical treatment in patients with this profile. The objective of the present study is to describe initial experience of MitraClip® therapy in Spain. Retrospective observational study including all patients treated between November 2011 and July 2013 at the 4 Spanish hospitals recording the highest numbers of implantations. A total of 62 patients (77.4% men) were treated, mainly for restrictive functional mitral regurgitation (85.4%) of grade III (37%) or grade IV (63%), mean (standard deviation) ejection fraction 36% (14%), and New York Heart Association functional class III (37%) or IV (63%). Device implantation was successful in 98% of the patients. At 1 year, 81.2% had mitral regurgitation ≤ 2 and 90.9% were in New York Heart Association functional class ≤ II. One periprocedural death occurred (sepsis at 20 days post-implantation) and another 3 patients died during follow-up (mean, 9.1 months). Two patients needed a second implantation due to partial dehiscence of the first device and 2 others underwent heart transplantation. In Spain, MitraClip® therapy has principally been aimed at patients with functional mitral regurgitation, significant systolic ventricular dysfunction, and high surgical risk. It is considered a safe alternative treatment, which can reduce mitral regurgitation and improve functional capacity. Copyright © 2014 Sociedad Española de Cardiología. Published by Elsevier Espana.

Reflux symptoms are common in pregnancy, but their association with fat ingestion is unclear. To investigate an association of dietary fats with heartburn and regurgitation in pregnancy. This is a prospective study in which 89 pregnant women (gestational age 34 +/- 4 weeks) attending a low-risk prenatal outpatient clinic were asked to provide information on the frequency they experienced heartburn and regurgitation. Fat ingestion was estimated by means of a 24-h diet record. Symptomatic patients were compared with those with no reflux symptoms (n = 20). Heartburn once a week or more often occurred in 56 of the 89 patients (63%). The ingested amount of polyunsaturated fatty acids was higher in patients with heartburn (11.2 +/- 6.4 vs. 7.7 +/- 3.5 mg; P = 0.022) than in controls after adjusting for age, gain weight during pregnancy, ingestion of caffeine and vitamin C, and total energetic intake. The ingestion of monounsaturated fatty acids was higher in patients with heartburn, but with a borderline statistical significance (16.1 +/- 11 vs. 11.8 +/- 6.5 mg; P = 0.061). No association was observed between the consumption of fats and regurgitation. This study suggests that heartburn in the third trimester of pregnancy is associated with the ingestion of polyunsaturated fatty acids.

The aim of this study was to evaluate the outcome in a series of patients with Ebstein's anomaly and a failing right ventricle (RV) undergoing tricuspid valve (TV) repair and bidirectional Glenn cavopulmonary anastomosis (BDG). Between January 2006 and September 2013, 11 consecutive patients diagnosed with severe forms of Ebstein's anomaly and a failing RV underwent TV surgery and BDG. The mean age was 16.5 ± 7 years. Most frequently found symptoms were cyanosis, dyspnea, and arrhythmias. The azygos or hemiazygos veins were left open. The TV was repaired using the "peacock tail" technique, which consisted of total detachment of the anterior and posterior leaflets of the TV and rotation in both directions reimplanting them to the true annulus. The mean follow-up was 3.8 ± 2.4 years (range three months to six years). Hospital mortality was 9% (one patient). TV repair was possible in 10 patients. None of the patients had AV block postoperatively. At one year after surgery, the indexed RV and RA diameter were reduced significantly versus the preoperative data (p = 0.003 and p TV area were 1.2 ± 0.42 and 1.6 ± 0.6 (mm/m2), significantly lower than preoperatively (p = 0.001 and p = 0.008, respectively). The mean NYHA functional class, SaO2 , and cardiothoracic ratio were significantly improved. The peacock tail technique for TV repair in combination with BDG in patients with Ebstein's malformation and depressed RV function results in TV preservation, a low incidence of recurrent regurgitation, favorable functional status and RV function, and resolution of cyanosis. © 2014 Wiley Periodicals, Inc.

Full Text Available Abstract Mitral valve regurgitation is a relatively common and important heart valve lesion in clinical practice and adequate assessment is fundamental to decision on management, repair or replacement. Disease localised to the posterior mitral valve leaflet or focal involvement of the anterior mitral valve leaflet is most amenable to mitral valve repair, whereas patients with extensive involvement of the anterior leaflet or incomplete closure of the valve are more suitable for valve replacement. Echocardiography is the recognized investigation of choice for heart valve disease evaluation and assessment. However, the technique is depended on operator experience and on patient's hemodynamic profile, and may not always give optimal diagnostic views of mitral valve dysfunction. Cardiac catheterization is related to common complications of an interventional procedure and needs a hemodynamic laboratory. Cardiac magnetic resonance (MRI seems to be a useful tool which gives details about mitral valve anatomy, precise point of valve damage, as well as the quantity of regurgitation. Finally, despite of its higher cost, cardiac MRI using cine images with optimized spatial and temporal resolution can also resolve mitral valve leaflet structural motion, and can reliably estimate the grade of regurgitation.

Full Text Available Systemic lupus erythematosus (SLE is a heterogeneous autoimmune disease with a wide range of clinical and serological manifestations. Cardiac disease among patients with SLE is common and can involve the pericardium, myocardium, valves, conduction system, and coronary arteries. We are reporting a case of SLE in a young woman that is unique is unique in that initial symptoms consisted of pericarditis and hemorrhagic tamponade which remained progressive and resistant to aggressive immunosuppressive treatment and led to severe cardiomyopathy (ejection fraction of 25% and severe (+4 mitral regurgitation. Her immunosuppressive treatment included hydroxychloroquine, high-dose steroids, intravenous immunoglobulins, azathioprine, and mycophenolate mofetil. Her disease progression was felt to be due to underlying uncontrolled SLE because the complement levels remained persistently low throughout the entire course and PET Myocardial Perfusion and Viability study showed stable persistent active inflammation. Eventually, she was treated with cyclophosphamide which led to improvement in ejection fraction to 55% with only mild mitral regurgitation.

Full Text Available Abstract Background Methicillin-resistant S. aureus (MRSA with low susceptibility to glycopeptides is uncommon. Case presentation The case of a 50-year-old non-drug addict patient presenting with tricuspid valve infective endocarditis (IE by MRSA resistant to vancomycin and linezolid is presented. There was response only to quinupristin/dalfopristin. He had a motorcycling accident four years before undergoing right above-the-knee amputation and orthopaedic fixation of the left limb. There were multiple episodes of left MRSA-osteomyelitis controlled after surgery and vancomycin therapy. MRSA isolated from the blood at the time of IE presented with the same profile than the isolated four years earlier. Sequential treatment with teicoplanin-cotrimoxazole and Linezolid associated to vancomycin – rifampicin – cotrimoxazole had no improvement. Infection was controlled after 28 days of therapy with quinupristin/dalfopristin. Conclusion The literature presents only a few cases of MRSA IE not susceptible to glycopeptides in not drug addicted patients. This case shows the comparison of a highly-resistant MRSA after previous S. aureus osteomyelitis treated with glycopeptides. This is the first description of successful treatment of resistant-MRSA IE of the tricuspid valve complicated by multiple pulmonary septic infarction with quinupristin/dalfopristin

Background/Aim MR is an important complication after PMV. Transthoracic echocardiography is widely used to screen for native MR, but can be limited with PMV. Cine-CMR holds potential to non-invasively assess regurgitant severity based on MR-induced inter-voxel dephasing. This study evaluated routine cine-CMR for visual assessment of prosthetic mitral valve (PMV) associated mitral regurgitation (MR). Methods Routine cine-CMR was performed at 9 sites. A uniform protocol was used to grade MR based on jet size in relation to the left atrium (mild 2/3): MR was graded in each long axis orientation, with overall severity based on cumulative grade. Cine-CMR was also scored for MR density and pulmonary vein systolic flow reversal (PSFR). Visual interpretation was compared to quantitative analysis in a single center (derivation) cohort, and to transesophageal echocardiography (TEE) in a multicenter (validation) cohort. Results The population comprised 85 PMV patients (59% mechanical, 41% bioprosthetic). Among the derivation cohort (n=25), quantitative indices paralleled visual scores, with stepwise increases in jet size and density in relation to visually graded MR severity (both p=0.001): Patients with severe MR had nearly a 3-fold increase in quantitative jet area (p=0.002), and 2-fold increase in density (p=0.04) than did others. Among the multicenter cohort, cine-CMR and TEE (Δ=2±3 days) demonstrated moderate agreement (κ=0.44); 64% of discordances differed by ≤ 1 grade (Δ=1.2±0.5). Using a TEE reference, cine-CMR yielded excellent diagnostic performance for severe MR (sensitivity, negative predictive value=100%). Patients with visually graded severe MR also had more frequent PVSFR (pcine-CMR. Conclusions Cine-CMR is useful for assessment of PMV-associated MR, which manifests concordant quantitative and qualitative changes in size and density of inter-voxel dephasing. Visual MR assessment based on jet size provides an accurate non-invasive means of screening for

2018-02-01

Mitral regurgitation commonly improves after implantation of a left ventricular assist device without concomitant valvular repair owing to the mechanical unloading of the left ventricle. However, the development (or persistence) of significant mitral regurgitation after implantation of a left ventricular assist device is associated with adverse clinical events. We present a case of a left ventricular assist device patient who successfully underwent a percutaneous MitraClip procedure for repair of persistent late postoperative mitral insufficiency with demonstrable clinical and hemodynamic improvement.

Full Text Available É relatado o caso de 1 paciente que apresentou endocardite aguda da valva tricúspide pós-aborto, cujo agente causal era o S. aureus. Como não houvesse resposta favorável ao tratamento antibiótico (gentamicina, vancomicina e oxacilina, optou-se pela intervenção, vinte dias após a internação. Foi praticada excisão de uma vegetação única e do tecido valvar adjacente, na comissura ântero-posterior e plicatura anular. O resultado foi favorável, com cura clínica. O exame ecocardiográfico confirmou a presença da vegetação no pré-operatório e o funcionamento conservado da valva, após a plastia. O tratamento cirúrgico, com retirada do tecido infectado e preservação da valva constitui uma alternativa aplicável a certos casos de endocardite aguda das valvas atrioventriculares.One case of acute bacterial endocarditis of the tricuspid valve caused by S. aureus and following a septic abortion is presented. Surgical treatment was indicated after failure of antibiotics. Operation consisted of excision of a large vegetation adherent to the anterior and posterior cusps at the commisure and of the affected valvar tissue. Annular plicature at the segment corresponding to the posterior cuspid was employed to maintain competence. Clinical result was very satisfactory with resolution of sepsis. Dopplerecocardiography revealed the presence of the vegetation before the operation and showed a small regurgitation after valvoplasty. Conservative operation upon the atrioventricular valves must be kept in mind as an alternative in the treatment of acute bacterial endocarditis.

In gastro-oesophageal reflux disease (GERD), heartburn responds well to acid suppression, but regurgitation is a common cause of incomplete treatment response. To assess the prevalence and burden of persistent, frequent regurgitation in primary care patients with GERD treated with acid suppression. We analysed observational data from 134 sites across six European countries in patients diagnosed with GERD. Within 3 months of the index visit, symptoms were assessed using the Reflux Disease Questionnaire, and their impact on sleep and work productivity with the Quality of Life in Reflux and Dyspepsia questionnaire and the Work Productivity and Activity Impairment Questionnaire, respectively. Patients provided information on concomitant over-the-counter (OTC) GERD medication use. Persistent, frequent (3-7 days/week) regurgitation was reported by 13.2% (153/1156) of GERD patients with no heartburn on acid suppression; the prevalence was very similar for patients with up to 2 days/week of ongoing mild heartburn. Among patients without heartburn, sleep disturbance of any type was reported by 50.7-60.1% with persistent, frequent regurgitation, compared with 38.1-51.1% and 14.4-19.2% of those with less frequent or no regurgitation respectively. Persistent, frequent regurgitation was associated with increased use of OTC medication and more hours of work missed, whether mild, infrequent heartburn was present or not. Frequent regurgitation, which persisted in 12-13% of patients with no or infrequent, mild heartburn on acid suppression, negatively affected sleep and work productivity, and increased use of OTC medication. Persistent, frequent regurgitation is problematic for primary care patients with GERD. © 2013 Blackwell Publishing Ltd.

Despite the paucity of data available, orally administered angiotensin-converting enzyme (ACE) inhibitors are empirically used in horses with valvular regurgitation. Evaluate the echocardiographic and hormonal changes in response to oral benazepril in horses with left-sided valvular regurgitation. Prospective, randomised double-blind, placebo-controlled trial. Horses with mitral valve (MR) and/or aortic valve regurgitation (AR) received oral benazepril (n = 6) at a dosage of 1 mg/kg q 12 h or a placebo (n = 5) for 28 days. Echocardiography was performed before drug administration and after 28 days of treatment. Plasma renin activity, serum ACE activity, angiotensin II concentration, aldosterone concentration and biochemical variables were measured before drug administration and after 7 and 28 days of treatment. Relative to baseline, horses treated with benazepril had statistically significant reduction in left ventricular internal diameter in systole (mean difference between groups = -0.97 cm; 95% CI = -1.5 to -0.43 cm), aortic sinus diameter (-0.31 cm; -0.54 to -0.07 cm), and percentage of the aortic annulus diameter occupied by the base of the AR jet (-17.05%; -31.17 to -2.93%) compared with horses receiving a placebo. In addition, horses treated with benazepril had a significantly greater increase in cardiac output (11.95 L/min; 1.17-22.73 L/min) and fractional shortening (7.59%; 3.3-11.88%) compared with horses receiving a placebo. Despite profound serum ACE inhibition, renin activity and concentrations of angiotensin II and aldosterone were not significantly different between treatment groups or among time points. Very small sample size and short treatment period. Treatment with oral benazepril resulted in statistically significant echocardiographic changes that might indicate reduced cardiac afterload in horses with left-sided valvular regurgitation. Additional studies with a larger sample size will be necessary to determine if administration of benazepril is

Remarkable case of uncorrected type IC tricuspid atresia with adaptive pulmonary trunk dilatation to allow prolonged survival: Case report and CT fly-through

Directory of Open Access Journals (Sweden)

Zeke J. McKinney

Full Text Available A remarkable case of a surgically uncorrected Type IC (no great artery transposition, no pulmonary stenosis tricuspid atresia surviving to adulthood is presented. This is a case of an adult female of 30 years of age with an atretic tricuspid valve, an atrial septal defect, a large ventricular septal defect, and a dilated pulmonary trunk. Surgical correction was never conducted on this heart with a significant congenital cardiac defect, and yet the individual survived into a fourth decade. Without surgical correction, survival to adulthood in tricuspid atresia is exceedingly rare. Survival depends on a high degree of ventricular shunting with limited pulmonary outflow obstruction. The resistance of this obstruction must be both low enough to maintain increased pulmonary blood flow and high enough to prevent systemic-level pressures upon the pulmonary vasculature. The unique finding of a significantly dilated pulmonary trunk is described, which presumably allowed this individual to survive to adulthood. This complex physiology is described and augmented with high-resolution images of this cardiac specimen. These were made possible by the application of a plastination process prior to obtaining high-resolution multi-slice computed tomography imaging studies. The result is a study comprised of multiplanar and three-dimensional data detailing the anatomic features of the specimen, which were then used to create reconstructions of the specimen for visualization of the anatomy. An understanding of the development and morphology of tricuspid atresia is essential for successful surgical correction in new patients with this congenital malformation.

Clinical presentation, diagnosis and management of acute mitral regurgitation following acute myocardial infarction

Directory of Open Access Journals (Sweden)

Rengin Çetin Güvenç

2016-03-01

Full Text Available Acute mitral regurgitation (MR is a frequent complication of acute myocardial infarction, with a variable presentation depending on the severity of MR and the integrity of the subvalvular apparatus. While most cases are asymptomatic or have mild dyspnea, rupture of chordae tendinea or papillary muscles are catastrophic complications that may rapidly lead to cardiogenic shock and death. Despite the presence of pulmonary edema and/or cardiogrenic shock, the murmur of acute MR is usually subtle due to rapid equalization of left atrial and left ventricular pressure gradient, and therefore misleading. Echocardiography is the definite diagnostic modality, allowing quantification of the severity of MR and the structural abnormalities within the subvalvular apparatus. Severe MR accompanied by rupture of chordae or papillary muscles should be managed with temporary stabilization with medical treatment or with mechanical circulatory support, with subsequent surgical intervention to repair or replace the valve.

Neisseria elongata, a common oral bacterium, has been recognized as a cause of infections such as infective endocarditis, septicemia, and osteomyelitis. Neisseria-induced infective endocarditis, although infrequently reported, typically arises after dental procedures. Without antibiotic therapy, its complications can be severe. We report the case of a 27-year-old man who presented with fever, severe dyspnea, and a leg abscess from cellulitis. An echocardiogram showed a vegetation-like echogenic structure on the septal leaflet of the patient's native tricuspid valve, and an insignificant Gerbode defect. Three blood cultures grew gram-negative, antibiotic-susceptible coccobacilli that were confirmed to be N. elongata. Subsequent DNA sequencing conclusively isolated N. elongata subsp nitroreducens as the organism responsible for the infective endocarditis. The patient recovered after 21 days of antibiotic therapy. In addition to the patient's unusual case, we discuss the nature and isolation of N. elongata and its subspecies.

Background Advancements in medical technology and increased life expectancy have been described as contributing to the evolution of endocarditis. We sought to determine whether there has been a change in the incidence, demographics, microbiology, complications, and outcomes of infective endocarditis over a ten-year time span. Methods We screened 28,420 transthoracic and transesophageal echocardiogram reports performed at our center for the following indications: fever, masses, emboli (including stroke), sepsis, bacteremia, and endocarditis in two time periods: 1999 through 2000 and 2009 through 2010. Data were collected from diagnosed endocarditis cases. Results Overall, 143 cases of infective endocarditis were analyzed (48 in 1999-2000 and 95 in 2009-2010). The endocarditis incidence per number of admissions remained nearly constant at 0.113% for 1999-2000 and 0.148% for 2009-2010 (p = 0.153). However, tricuspid valve involvement increased markedly from 6% to 36% (p endocarditis at our center has not changed and mortality remains high, but the “face of endocarditis” in Kentucky has evolved with an increased incidence of tricuspid valve involvement, valvular complications, and embolic events.

The ultrasound assessment of RV structure and function is often sub-optimal. The range of excursions of the mitral or tricuspid annulus measured in millimetre by 2D or TM-mode in centimetre per second by DTI-mode echocardiography has been shown to reflect the systolic function of both ventricles. We studied a new technique based on a tissue tracking algorithm that is ultrasound beam angle independent for automated detection of tricuspid annular displacement (TAD) (QLAB, Philips Medical Imaging). Twenty-six patients (pts) referred for magnetic resonance imaging (MRI) and 44 control subjects underwent a complete transthoracic echocardiography. MRI of the right ventricular ejection fraction (RVEF) was correlated by linear regression with TAD. Sixteen pts (61.5%) exhibited right ventricular systolic dysfunction (MRI RVEFTAD (R(2)=0,65; pTAD TAD values exceeding this cut-off point (mean: 16.9+/-1.64mm; range: 13.3 to 24.8mm). Negative correlation was found between TAD and age (R(2)=0,36; pTAD with MRI RVEF. TAD is a simple, rapid, and non-invasive tool for right ventricular systolic function assessment.

Compare variability in flow measurements by phase contrast MRI, performed at different locations in the aorta and pulmonary artery (PA) using breath-held (BH) and free-breathing (FB) sequences. Fifty-seven patients with valvular heart disease, confirmed by echocardiography, were scanned using BH technique at 3 locations in the ascending aorta (SOV = sinus of Valsalva, STJ = sinotubular junction, ASC = ascending aorta at level of right pulmonary artery) and 2 locations in PA. Single FB measurement was obtained at STJ for aorta. Obtained metrics (SV = stroke volume, FV = forward volume, BV = backward volume, RF = regurgitant fraction) were evaluated separately for patients with aortic regurgitation (AR, n = 31) and mitral regurgitation (n = 26). No difference was noted between the two measurements in the PA. Significant differences were noted in measured SV at different aortic locations. SV measurements obtained at ASC correlated best with the measurements obtained in the PA. Strongest correlation of AR was measured at the STJ. Measurements of flow volumes by phase contrast MRI differ depending on slice location. When using stroke volumes to calculate pulmonary to systemic blood flow ratio (Qp/Qs), ASC should be used. For quantifying aortic regurgitation, measurement should be obtained at STJ. (orig.)

Background and aim It is not known why some reflux episodes evoke symptoms and others do not. We investigated the determinants of perception of gastro‐oesophageal reflux. Methods In 32 patients with symptoms suggestive of gastro‐oesophageal reflux, 24 hour ambulatory pH and impedance monitoring was performed after cessation of acid suppressive therapy. In the 20 patients who had at least one symptomatic reflux episode, characteristics of symptomatic and asymptomatic reflux episodes were compared. Results A total of 1807 reflux episodes were detected, 203 of which were symptomatic. Compared with asymptomatic episodes, symptomatic episodes were associated with a larger pH drop (pheartburn; 14.8% of the symptomatic reflux episodes were weakly acidic. In total, 426 pure gas reflux episodes occurred, of which 12 were symptomatic. Symptomatic pure gas reflux was more frequently accompanied by a pH drop than asymptomatic gas reflux (pHeartburn and regurgitation are more likely to be evoked when the pH drop is large, proximal extent of the refluxate is high, and volume and acid clearance is delayed. Sensitisation of the oesophagus occurs by preceding acid exposure. Weakly acidic reflux is responsible for only a minority of symptoms in patients off therapy. Pure gas reflux associated with a pH drop (“acid vapour”) can be perceived as heartburn and regurgitation. PMID:16120760

The influence of left ventricular volume variations and regurgitant fraction variations upon left ventricular ejection fraction during exercise was examined using equilibrium radionuclide angiography in patients suffering from aortic regurgitation. Ejection fraction (EF), regurgitant fraction (RF), end diastolic volume (EDV) and end systolic volume (ESV) variations from rest to peak exercise were determined in 44 patients suffering from chronic aortic regurgitation (AR) and in 8 healthy volunteers (C). In C, EF increased (+0.10±0.03, P<0.01) and ESV decreased significantly (-23%±12%, P<0.01), RF and EDV did not vary significantly. In AR patients, EF, EDV and ESV did not vary significantly because of important scattering of individual values. Changes in EF and ESV were inversely correlated (r=-0.79, P<0.01) and RF decreased significantly (-0.12±0.10, P<0.01). Volumes and EF changes during exercise occurred in three different ways. In a 1st subgroup of 7 patients, EF increased (+0.09±0.03, P<0.05) in conjunction with a reduction of ESV (-24%±12%, P<0.05) without a significant change in EDV. In a 2nd group of 22 patients, EF decreased (-0.04±0.07, P<0.01) in association with an increase in ESV (+17%±16%, P<0.01) and no changes in EDV. In a 3rd subgroup of 15 patients, EF decreased (-0.02±0.06, P<0.01) despite a reduction in ESV (-7%±6%, P<0.01) because of a dramatic EDV decrease (-10%±6%, P<0.05). In this subgroup, changes in EF were inversely correlated with changes in ESV (r=-0.55, P<0.01) and positively related to EDV variations (r=0.42, P=0.02). EDV changes were weakly, but significantly, correlated to RF decrease (r=0.39, P<0.05). We conclude that changes in left ventricular ejection fraction during exercise in patients with chronic aortic regurgitation are significantly related in some patients to changes in ventricular loading conditions as well as contractile state.

Limited data exist on the impact of regurgitation on health-related quality of life (HRQOL) in gastro-oesophageal reflux disease (GORD). We assessed the relationship between regurgitation frequency and HRQOL before and after acid suppression therapy in GORD. We used data from two randomised trials of AZD0865 25-75 mg/day versus esomeprazole 20 or 40 mg/day in non-erosive reflux disease (NERD) (n=1415) or reflux oesophagitis (RO) (n=1460). The Reflux Disease Questionnaire was used to select patients with frequent and intense heartburn for inclusion and to assess treatment response. The Quality of Life in Reflux and Dyspepsia (QOLRAD) questionnaire was used to assess HRQOL. At baseline, 93% of patients in both the NERD and RO groups experienced regurgitation. Mean QOLRAD scores were similar for NERD and RO at baseline and at week 4 and disclosed decremental HRQOL with increasing frequency of regurgitation; a clinically relevant difference of >0.5 in mean QOLRAD scores was seen with regurgitation ≥4 days/week versus <4 days/week. The prevalence of frequent, persistent regurgitation (≥4 days/week) at week 4 among heartburn responders (≤1 day/week of mild heartburn) was 28% in NERD and 23% in RO. QOLRAD scores were higher among heartburn responders. There was a similar pattern of impact related to regurgitation frequency in heartburn responders compared with the group as a whole. Frequent regurgitation was associated with a clinically relevant, incremental decline in HRQOL beyond that associated with heartburn before and after potent acid suppression in both NERD and RO.

Three patients with pulmonic regurgitation and no evidence of pulmonary hypertension were investigated. These patients had low pitched diastolic murmurs which increased on inspiration, evidence of connective tissue disease as manifested by lax joints and hyperextensible skin, and marked hilar dance which extended up to the peripheral vessels. Suprasternal echocardiography revealed dilatation and increased systolic expansion of the right pulmonary artery (RPA) (25% and 28%, respectively) in two patients; the third patient had a normal RPA dimension in diastole and a marked increase in diameter (88%) in systole. Thus, these three patients demonstrated hyperdistensibility of the RPA. The spectral signal from the pulsed doppler echocardiograph showed evidence of turbulent blood flow in diastole (wide dispersion of the dots) in the right ventricular outflow tract in all three patients. This pattern was indicative of pulmonic regurgitation. In summary, the combined use of echocardiography and Doppler ultrasound is useful in the evaluation of patients with pulmonic regurgitation.

Full Text Available Abstract A 48 year old man was transferred to our department with cardiogenic shock, pyrexia, a high white cell count and significant serum troponin T level. Clinical evaluation revealed severe mitral regurgitation secondary to a flail of both mitral valve leaflets. An emergency cardiac catheterisation did not reveal any significant coronary artery disease. Left ventricular angiogram and echocardiography demonstrated a good left ventricular function and massive mitral regurgitation. Blood cultures were negative for aerobics, anaerobics and fungi. The patient underwent emergency mitral valve replacement with a mechanical valve. Intraoperatively, the posteromedial papillary muscle was found to be ruptured. Histology of the papillary muscle revealed myocardial necrosis with no signs of infection. Cultures obtained from a mitral valve specimen were negative. The patient's recovery was uneventful and he was discharged on the 6th postoperative day.

To determine whether the location of aortic valve calcium (AVC) influences the location of paravalvular regurgitation (PR). PR is an adverse effect of transcatheter aortic valve implantation (TAVI) with a negative effect on long-term patient survival. The relationship between AVC and the occurrence of PR has been documented. However, the relationship between the distribution of AVC and the location of PR is still sparsely studied. The purpose of this study was to correlate severity and location of AVC with PR in patients treated with TAVI. Fifty-six consecutive patients who underwent transaortic or transapical TAVI and had preoperative computed tomography scans were included in this retrospective study. The volume, mass and location of AVC was determined and compared between patients with and without PR using a non-parametric t-test. Postoperative echocardiography was performed to determine the presence and location of PR, which was associated with the cusp with highest AVC using a χ(2) test. Valve deployment was successful in all 56 patients. PR was present in 38 patients (68%) after TAVI. There was a non-significantly higher volume of AVC in the PR group [214 (70-418) vs 371 (254-606) cm(3), P = 0.15]. AVC mass was significantly higher in patients with PR than in patients without PR [282 (188-421) vs 142 (48-259) mg, respectively, P = 0.043]. The location of PR was determined in 36 of these patients. Of these 36 patients, PR occurred at the cusp with the highest AVC in 20 patients (56%, χ(2) P = 0.030). In our population, PR was associated with greater AVC mass. Moreover, the location of PR was associated with the cusp with the highest amount of AVC. © The Author 2014.

Ventricular pacing is most commonly performed at the right ventricular (RV) apex. This is not without risk as placement requires crossing the tricuspid valve (TV) and may cause valvular dysfunction and dyssynchronous activation of the ventricles. The fact that the tricuspid valve lies more apically than the mitral valve allows for the possibility of pacing the ventricles from the right atrium (RA) via the “atrio-ventricular septum” without crossing the TV or entering the coronary sinus (CS). In order to mitigate far field activation inherent to current pacing technology, we constructed a novel lead in which the cathode and anode are both intra-myocardial. We demonstrate safety and efficacy of this novel lead for ventricular pacing at the atrio-ventricular septum in canines, including improved synchronous activation of both ventricles, improved differentiation in ventricular versus atrial sensing, while providing reliable ventricular capture, opening novel and a potentially safer alternative to human cardiac resynchronization therapy.

Pulmonary hypertension (PH) is commonly associated with myxomatous mitral valve disease (MMVD). Because dogs with PH present without measureable tricuspid regurgitation (TR), it would be useful to investigate echocardiographic variables that can identify PH. To investigate associations between estimated systolic TR pressure gradient (TRPG) and dog characteristics and selected echocardiographic variables. 156 privately owned dogs. Prospective observational study comparing the estimations of TRPG with dog characteristics and selected echocardiographic variables in dogs with MMVD and measureable TR. Tricuspid regurgitation pressure gradient was significantly (P modeled as linear variables LA/Ao (P modeled as second order polynomial variables: AT/DT (P = .0039) and LVIDDn (P value for the final model was 0.45 and receiver operating characteristic curve analysis suggested the model's performance to predict PH, defined as 36, 45, and 55 mmHg as fair (area under the curve [AUC] = 0.80), good (AUC = 0.86), and excellent (AUC = 0.92), respectively. In dogs with MMVD, the presence of PH might be suspected with the combination of decreased PA AT/DT, increased RVIDDn and LA/Ao, and a small or great LVIDDn.

Full Text Available Primary mediastinal B-cell lymphoma (PMBCL is an uncommon aggressive subset of diffuse large B-cell lymphomas. Although PMBCL frequently spreads locally from the thymus into the pleura or pericardium, it rarely invades directly through the heart. Herein, we report a case of a young Mexican female diagnosed with PMBCL with clear infiltration of lymphoma through the cardiac wall and into the right atrium and tricuspid valve leading to tricuspid regurgitation. This was demonstrated by cardiac MRI and transthoracic echocardiogram. In addition, cardiac MRI and CT scan of the chest revealed the large mediastinal mass completely surrounding and eroding into the superior vena cava (SVC wall causing a collar of stokes. The cardiac and SVC infiltration created a significant therapeutic challenge as lymphomas are very responsive to chemotherapy, and treatment could potentially lead to vascular wall rupture and hemorrhage. Despite the lack of conclusive data on chemotherapy-induced hemodynamic compromise in such scenarios, her progressive severe SVC syndrome and respiratory distress necessitated urgent intervention. In addition to the unique presentation of this rare lymphoma, our case report highlights the safety of R-CHOP treatment.

This study was undertaken to determine whether postoperative outcomes after laparoscopic Heller myotomy with anterior fundoplication could be predicted by preoperative findings on esophagography. Preoperative barium esophagograms of 135 patients undergoing laparoscopic Heller myotomy with anterior fundoplication were reviewed. The number of esophageal curves, esophageal width, and angulation of the gastroesophageal junction (GEJ) were determined; correlations between these determined parameters and symptoms were assessed using linear regression analysis. The number of esophageal curves correlated with the preoperative frequency of dysphagia, vomiting, chest pain, regurgitation, and heartburn. The width of the esophagus negatively correlated with the preoperative frequency of regurgitation. The angulation of the GEJ did not correlate with preoperative symptoms. Laparoscopic Heller myotomy with anterior fundoplication significantly reduced the frequency and severity of all symptoms, regardless of the number of esophageal curves, esophageal width, or angulation of the GEJ. Laparoscopic Heller myotomy with anterior fundoplication provides dramatic palliation for achalasia. More esophageal curves on preoperative esophagography correlate well with the frequency of a broad range of preoperative symptoms, including the frequency of dysphagia and regurgitation. Patients experience dramatically improved frequency and severity of symptoms after laparoscopic Heller myotomy with anterior fundoplication for achalasia regardless of the number of esophageal curves, esophageal width, or the angulation of the GEJ. Findings on barium esophagogram, in evaluating achalasia, should not deter the application of laparosocopic Heller myotomy with anterior fundoplication.

Full Text Available We report a 2.5-year-old girl who presented with hoarseness of voice since 3 months of age and failure to thrive. Chest X-ray showed cardiomegaly with a deviation of the trachea and mediastinum to the right side. Two-dimensional echocardiography showed decreased flow across the right pulmonary artery, a small atrial septal defect (ASD with a right-to-left shunt, and a dilated right atrium and right ventricle with severe tricuspid regurgitation suggestive of severe pulmonary hypertension. A silent large patent ductus arteriosus was also seen. Multiple detector computerized tomography aortogram confirmed the findings of absent right pulmonary artery and hypoplastic right lung with small cystic lesions suggestive of congenital cystic adenomatoid malformation in the right lower lobe. Hoarseness of voice was due to the left vocal cord palsy probably secondary to severe pulmonary hypertension (Ortner′s syndrome.

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 Background: Chronic obstructive pulmonary disease (COPD has considerable effects on cardiac functions, including those of the right ventricle, left ventricle, and pulmonary blood vessels. Most of the increased mortality associated with COPD is due to cardiac involvement. Echocardiography provides a rapid, noninvasive, portable, and accurate method to evaluate the cardiac changes. Aims: To assess the cardiac changes secondary to COPD by echocardiography and to find out the correlation between echocardiographic findings and severity of COPD, if there is any. Materials and Methods: A total 40 of patients of COPD were selected and staged by pulmonary function test (PFT and evaluated by echocardiography. Results: On echocardiographic evaluation of COPD, 50% cases had normal echocardiographic parameters. Measurable tricuspid regurgitation (TR was observed in 27/40 cases (67.5%. Pulmonary hypertension (PH, which is defined as systolic pulmonary arterial pressure (sPAP > 30 mmHg was observed in 17/27 (63% cases in which prevalence of mild, moderate, and severe PH were 10/17 (58.82%, 4/17 (23.53%, and 3/17 (17.65%, respectively. The frequencies of PH in mild, moderate, severe, and very severe COPD were 16.67%, 54.55%, 60.00%, and 83.33%, respectively. Right atrial pressure was 10 mmHg in 82.5% cases and 15 mmHg in 17.5% cases. Cor pulmonale was observed in 7/17 (41.17% cases; 7.50% cases had left ventricle (LV systolic dysfunction and 47.5% cases had evidence of LV diastolic dysfunction defined as A ≥ E (peak mitral flow velocity of the early rapid filling wave (E, peak velocity of the late filling wave caused by atrial contraction (A on mitral valve tracing. Left ventricle hypertrophy was found in 22.5% cases. Conclusion : Prevalence of PH has a linear relationship with severity of COPD and severe PH is almost associated with cor pulmonale. Echocardiography helps in early detection of cardiac complications in COPD cases giving time for early

Mitral regurgitation (MR) is frequent and associated with increased mortality and morbidity when severe. It may be caused by intrinsic valvular disease (primary MR) or ventricular deformation (secondary MR). Imaging has a critical role to document the severity, mechanism, and impact of MR on heart function as selected patients with MR may benefit from surgery whereas other will not. In patients planned for a surgical intervention, imaging is also important to select candidates for mitral valve (MV) repair over replacement and to predict surgical success. Although standard transthoracic echocardiography is the first-line modality to evaluate MR, newer imaging modalities like three-dimensional (3D) transesophageal echocardiography, stress echocardiography, cardiac magnetic resonance (CMR), and computed tomography (CT) are emerging and complementary tools for MR assessment. While some of these modalities can provide insight into MR severity, others will help to determine its mechanism. Understanding the advantages and limitations of each imaging modality is important to appreciate their respective role for MR assessment and help to resolve eventual discrepancies between different diagnostic methods. With the increasing use of transcatheter mitral procedures (repair or replacement) for high-surgical-risk patients, multimodality imaging has now become even more important to determine eligibility, preinterventional planning, and periprocedural guidance.

Gastroesophageal reflux (GER) is common in infancy and mainly treated through nonpharmacological interventions. Knowing the early warning signs of GER is important for nursing assessment. Untreated GER can become acute when an infant fails to gain weight and has recurrent, forceful vomiting. Further investigation of gastroesophageal reflux disease (GERD) is indicated when failure to gain weight, irritability, swallowing difficulties, regurgitation, and respiratory complications occur and should trigger referral to pediatric specialists. This article will share information about uncomplicated GER, GERD, and symptoms of these diagnoses, common screening tests, and treatment options. Copyright © 2017 Elsevier Inc. All rights reserved.
