Active clinical trials for "Tricuspid Valve Insufficiency"

Patients elected to undergo any type of left-sided valve surgery (either repair or replacement) with non severe tricuspid regurgitation and tricuspid annular dilation will be screened. Consenting patients fulfilling all inclusion and exclusion criteria will be included in the study and assigned to elective left-sided valve replacement or repair with or without concomitant tricuspid valve repair in a 1:1 fashion, using a blocked randomization scheme balanced within center.

The aim of this study was to investigate the procedural feasibility and 30-day results of transcatheter tricuspid valve repair using the MitraClip® system (Abbott Vascular) in selected, highly symptomatic patients with severe tricuspid regurgitation (TR).

The Eko CORE and DUO stethoscopes are FDA-approved electronic devices that have the capacity to record heart sounds. The study seeks to expand murmur detection to include VHD classification through the development of novel ML algorithms that are able to distinguish between systolic vs. diastolic vs. continuous murmurs, as well as classify VHD type and severity, using 4-point auscultation with Eko CORE and DUO electronic stethoscopes to record heart sounds.

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.

Functional tricuspid valve regurgitation is commonly co-existed with left-sided cardiac lesion, especially mitral valve stenosis. Both lesion were recommended to surgically fixed at the same setting. Residual tricuspid regurgitation may effects patients' outcome. The investigators would like to determine the incidence of significant residual tricuspid regurgitation after left-sided cardiac surgery and related clinical outcome.

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.

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.

Old trials aimed to evaluate Implantable Cardioverter-Defibrillator (ICD) safety and efficacy demonstrated a meaningful decreased rates of sudden death but an increased rate of hospitalization for heart failure . At the time, the chance that an endocardial lead could cause a significant tricuspid regurgitation (TR), leading to worsening heart failure, was not widely considered. Whereas, it is now well established that in patients with cardiac implantable electronic device (CIEDs), moderate or severe TR occurs frequently and it is associated with increased mortality and hospitalization for heart failure. The present study aims to report the long-term results of tricuspid valve repair and replacement surgery in patients with CIEDs Indeed, patients with TR and CIEDs can be divided in 2 categories: CIEDs induced TR and CIEDs associated TR. In patients with CIEDs induced TR, the valve dysfunction is directly caused by the lead with several mechanism such as mechanical interference with tricuspid valve (TV) leaflet mobility and coaptation (impingement), valve damage during lead placement or manipulation and sub-valvular entanglement. In patients with CIEDs associated TR the valve dysfunction is not directly caused by the lead. In 2009 approximately 720 000 CIEDs were implanted worldwide [7] and since then a continuous increase of CIEDs implantation was registered, with an estimation of 1.4 millions of CIEDs implantation in 2023. With this impressive number of CIEDs requirement, the need for surgical or trans-catheter treatment of severe TR CIEDs induced or associated, increased steadily in the past years and it likely will continue to increase in the next years. However, limited data are available regarding the outcome of tricuspid valve surgery in patients with CIEDs, particularly for the long-term results. With this study we aim to report the long-term result of tricuspid valve repair and replacement in patients with CIEDs.

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.

Impact of acute normovolemic hemodilution (ANH) using hydroxyethyl starch before initiating cardiopulmonary bypass (CPB) on whole blood viscoelastic profile after CPB has not been well established. Patients undergoing cardiac surgery employing moderate hypothermic CPB (n=40) are randomly allocated into one of two groups: in Group-ANH(n=20), ANH is applied by using a balanced hydroxyethyl starch (HES 130/0.6); and in Group-C, ANH is not applied. After weaning from CPB, intergroup differences of INTEM, EXTEM, FIBTEM and APTEM profiles are analyzed. As a primary outcome, inter-group difference between maxiaml clot firmness of EXTEM will be determined at 10 min after ANH in Group-ANH and that at control.
