Filter by:The study is a multi-center, prospective, early feasibility study to measure individual patient clinical outcomes and effectiveness, evaluate the safety and function, provide guidance for future clinical study designs and development efforts of the Edwards FORMA Tricuspid Transcatheter Repair System.
The TriCinch System™ is intended for percutaneous treatment of tricuspid regurgitation. It is a percutaneous catheter-based device designed for tricuspid valve repair in order to decrease effective cross-sectional area and relieve symptoms in patients with tricuspid valve regurgitation.
The purpose of this study is to gather clinical information on the hemodynamic performance of the Contour 3D® and Tri-Ad® Tricuspid Annuloplasty Rings in a post-market environment.
Tricuspid valve insufficiency (TI) is often noted on echocardiography. Although severe TI is known to cause significant morbidity and mortality, no good guidelines are available to guide intervention. Literature is mostly confined to tricuspid valve repair concomitant with mitral valve repair. Treatment options for isolated repair have not been investigated thoroughly. The investigators want to evaluate retrospectively the outcome of isolated tricuspid valve repair, performed in our center. By doing this, the investigators want to evaluate predictors of outcome after repair.
Few clinical evidence for the Contour 3D Tricuspid Annuloplasty Ring exists; therefore, in order to position this product on the market, a post-market release study was completed. The purpose of this study was to evaluate the hemodynamic performance of the Contour 3D® Tricuspid Annuloplasty Ring following Tricuspid Valve (TV) repair in a post-market environment.
The purpose of this pilot study is to evaluate mitral (left atrioventricular valve) and tricuspid (right atrioventricular valve (AVV)) regurgitation using cardiac magnetic resonance imaging (CMR) as the non-invasive "gold standard" compared to transthoracic echocardiography (TTE) to evaluate measurements of the width of the regurgitation jet (vena contracta (VC)) to demonstrate the utility of the VC as a means to objectively evaluate atrioventricular valve regurgitation. In addition, feasibility and other quantitative and qualitative measures of regurgitation will be compared between CMR and TTE. - Hypothesis 1: The ability to objectively evaluate atrioventricular valve regurgitation and VC width with TTE and CMR has a high feasibility rate with acceptable intra and inter-observer variability by two independent readers. - Hypothesis 2: There will be positive correlation between the TTE measurement of the VC width and quantitative assessment of atrioventricular valve regurgitation by TTE and CMR. - Hypothesis 3: There will be a positive correlation between the quantitative measurements of atrioventricular valve regurgitation by phase contrast velocity encoded CMR with quantitative values as measured by TTE. - Hypothesis 4: There will be a positive correlation between qualitative assessment of atrioventricular valve regurgitation by CMR compared to TTE.
Prospective registry for patients with severe isolated tricuspid regurgitation (TR) without significant left-sided valvular or myocardial diseases. Aim: To evaluate clinical course and prognostic factors of patients with severe isolated TR.
Right-sided heart disease has an important impact on the prognosis of patients with valvular heart disease. Up to now, Tricuspid Valve Regurgitation (TR) and right heart hemodynamics have not been extensively investigated. However, it is plausible that a significant degree of TR and the associated volume-overload of the right ventricle cause significant right ventricular wall stress. Although minor TR generally is well tolerated, major TR can lead to clinical symptoms, right ventricular dilatation and ultimately right ventricular heart failure. Up to now, the investigators do not dispose of any tools to diagnose and anticipate this unfavourable evolution. Nevertheless it is likely that right ventricular failure is preceded with a subclinical dysfunction of the right ventricle and a possibly reversible change in contractility of the myocardium. Recently, new techniques to evaluate the systolic function, the contractility and the hemodynamics of the heart have become available. First, this study will help us assessing the feasibility and accuracy of several imaging modalities in right-sided heart pathology with focus on TR and right heart myocardial performance. Second, this study will contribute to a better understanding of the hemodynamic effect of volume-overload and/or pressure-overload of the right ventricle. It will clarify the behaviour of TR, the evolution of right ventricular myocardial contractility and dysfunction during exercise and its impact on exercise capacity. By doing this, discrimination between well tolerated and ill-tolerated TR will be possible, thus identifying patients who might be eligible for treatment (medical, corrective, …).
This study is being done to determine whether or not new blood test(s) can determine the severity of heart conditions. Aortic stenosis, hypertrophic cardiomyopathy, mitral regurgitation, aortic regurgitation, artificial heart valve regurgitation or stenosis, and tricuspid valve regurgitation associated with pacemaker leads are the cardiac disorders under study. The blood tests involve analysis for von Willebrand Factor antigen and activity, von Willebrand Factor multimers, and brain natriuretic peptide (BNP) levels. The results of the blood tests will be compared to the information from the clinically-indicated echocardiogram and one blood test compared to another.
The mitral valve is the inflow valve into the main pumping chamber of the heart. It can become leaky or narrow, and cause blood to back up into the blood vessels of the lungs. When patients get symptoms from a leaky or narrow mitral valve, surgery is recommended to either fix or replace the valve. Many patients with mitral valve disease also develop a leaky tricuspid valve - the tricuspid valve is the inflow valve to the right side of the heart (the right heart pumps blood across the lungs). The amount of leakiness of the tricuspid valve is determined by an ultrasound test, and the amount of leakiness is graded as: none, mild, moderate, or severe. When a heart surgeon operates on a patient with a diseased mitral valve, he or she will fix the tricuspid valve if the tricuspid leakage is severe. This involves sewing a cloth-covered ring around the valve and narrowing it. If the tricuspid valve leakage is only mild (or absent), the surgeon will leave the tricuspid valve alone at the time of mitral valve surgery. If the tricuspid valve has moderate leakage surgeons are uncertain about what to do. In a recent review of thousands of patients across the nation having mitral valve surgery with moderately leaky tricuspid valves, 35 % of patients had tricuspid valve repair. Since the investigators don't know what the best approach is: to leave the moderately leaky tricuspid valve alone or to fix it with a cloth-covered ring, the investigators propose a study to determine which approach is best. Patients having mitral valve surgery with a moderately leaky tricuspid valve will be randomized to either 1. have a tricuspid valve repair or 2. to not have a tricuspid valve repair. The investigators will carefully follow these patients for two years and see if heart function is better among those who got their valve fixed.
