Filter by:The purpose of this study is to assess the efficacy and safety of implanting an Edwards Sapien XT Valve into the vena cava inferior (VCI; between right atrium and the hepatic vein) on clinical variables, exercise tolerance and well being in patients with severe tricuspid regurgitation and signs of right heart failure.
The goal of this study is to determine the short term safety (<30 days) and efficacy (6 months) of the heterotopic implantation of the Edwards-Sapien XT valve in the inferior vena cava for the treatment of severe tricuspid regurgitation in patients who are inoperable or at a very high surgical risk for tricuspid valve replacement.
Background and Aims Pacemaker implantation for treating bradyarrhythmias typically involves placing a pacing lead through the tricuspid valve (TV) into the right ventricular (RV) apex. It is now known that tricuspid regurgitation (TR) frequently results from this and may lead to increased morbidity or mortality. Recently, left ventricular (LV) pacing through an epicardial vein via the coronary sinus has been widely practiced due to the advent of biventricular pacing. This lead does not cross the TV, potentially reducing the risk of TV dysfunction and may also reduce the risk of LV dysfunction. The investigators hypothesize that LV pacing will prevent the onset of new TR or worsening of pre-existing TR in patients undergoing pacemaker implantation. Methods Patients receiving a pacemaker for sick sinus syndrome (n=20) with an LV ejection fraction <40% will be randomly allocated to receive either conventional RV pacing or LV pacing via the coronary sinus. Serial 2D and 3D transthoracic echocardiography will be performed before implantation, one day post implantation, then at 1 week, 1 month, 6 months and 1 year. The primary endpoints will be new onset TR and the diagnosis of at least moderate TR. Other endpoints include biventricular function, ventricular dyssynchrony, complications of device implantation, mortality and major cardiovascular events.
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.
De novo or progressive tricuspid regurgitation (TR) is not uncommonly observed following mitral valve surgery and associated with worse outcome. Hence, concomitant tricuspid valve annuloplasty (TVP) has been recommended for patients undergoing mitral valve surgery when tricuspid annular dilatation is present even in absence of significant TR. However, whether such a strategy of "prophylactic TVP" results in improved outcomes has not been shown to date by a prospective randomized study. The investigators goal is therefore to initiate such a study and evaluate the effect of concomitant TVP on mid- and long-term outcome in patients scheduled for mitral valve surgery and tricuspid annular dilatation but <2+ TR.
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.
