Active clinical trials for "Tricuspid Valve Insufficiency"

1050 patients with persistent/permanent atrial fibrillation (AF) will be studied using conventional and advanced (three-dimensional and deformation imaging) echocardiography. Patients with moderate/severe isolated secondary tricuspid regurgitation (STR) will undergo blood tests to assess their proteomic profile and cardiac CT to measure the tricuspid annulus geometry. The project will aim to 1. assess the prevalence of moderate/severe isolated STR in patients with AF; 2. identify the mechanisms associated with the development of moderate-severe STR in patients with AF; 3. identify the proteomic profile associated with significant growth of tricuspid valve leaflets as a mechanism to protect patients with AF from the development of moderate/severe STR; 4. evaluate the effects of the restoration of sinus rhythm on the severity of STR and the remodeling of the right heart cardiac structures (i.e. right ventricle, right atrium, and tricuspid valve apparatus).

The study is an early feasibility study to measure individual patient clinical outcomes and effectiveness, evaluate the safety and function of the DUO Transcatheter Tricuspid Coaptation Valve System (DUO System).

The purpose of this clinical study is to evaluate the safety and clinical efficacy of the VDyne System in the treatment of symptomatic severe tricuspid regurgitation (TR).

This study aims to investigate the safety and efficacy of the PASCAL leaflet repair system in the treatment of tricuspid regurgitation in a commercial use setting including all consecutive patients at the participating Centers in an observational fashion.

Retrospective prospective Multicentric clinical follow up of patients with severe tricuspid regurgitation after being treated with the TricValve® Transcatheter Bicaval Valves System.

To confirm the effectiveness and safety of the DragonFly-T transcatheter tricuspid valve repair system for the treatment of severe tricuspid regurgitation (TR) (TR grade ≥ 3+) who remained clinically symptomatic after guideline-directed medical treatment.

Comparison of cardiac synchronization and tricuspid regurgitation with or without leadless pacemaker pacing in different site

Tricuspid Regurgitation induces an asymmetric enlargement of the tricuspid valve (TV) annulus causing a reduction of leaflets coaptation. Annular dilation continues even after surgical treatment. The progressive nature of TR, inadequate surgical treatment, and high-risk patient population make TR an ideal target for transcatheter therapy. The TriFlo TFO System introduces a new concept for the treatment of tricuspid regurgitation. Its commissural anchoring is designed to respect TV leaflet integrity, mobility, and maintain RV contractility.

Tricuspid regurgitation is common in patients with severe left heart diseases, such as degenerative mitral regurgitation. However, the evidence base is insufficient to inform a decision about whether to perform concomitant tricuspid-valve repair during left heart surgery in patients who have mild tricuspid regurgitation. To inform decision making, we will conduct a multicenter, randomized trial to assess the benefits and risks of tricuspid-valve repair at the time of left heart diseases in patients with mild tricuspid regurgitation who were undergoing surgery for left heart surgery.

Functional tricuspid regurgitation (FTR) remains a common finding in patients with left-sided valvular heart diseases especially mitral valve regurgitation or stenosis. It is mainly caused by dilatation and flattening of the tricuspid valve (TV) annulus as a result of right ventricular (RV) enlargement and is inevitably affected by the RV function. Multiple studies support the better outcome of using rigid ring annuloplasty over suture repair for treating FTR in concern with the durability and freedom from residual regurgitation. These studies refer the superiority of rigid ring annloplasty to the three-dimensional configuration achieved by such rings which matches the normal tricuspid annulus and, at the same time, to the rigid support of the annulus. On the other hand, other studies support the use of flexible prosthetic bands like Dacron or polytetrafluroethilin (PTFE), especially over suture techniques, due to their easy applicability and availability with good postoperative results. Therefore, suture annyloplasty became nowadays less convenient for FTR repair since both flexible bands and rigid rings appeared to offer good midterm outcomes in recent meta-analysis studies. However, the ideal annuloplasty method for repairing FTR is still debatable between the three-dimensional (3D) rigid rings versus flexible prosthetic bands. In this retrospective comparative study, we share our experience with flexible fashioned bands in FTR.
