Active clinical trials for "Mitral Valve Insufficiency"

To establish the safety and effectiveness of the Edwards PASCAL Transcatheter Valve Repair System in patients with degenerative mitral regurgitation (DMR) who have been determined to be at prohibitive risk for mitral valve surgery by the Heart Team, and in patients with functional mitral regurgitation (FMR) on guideline directed medical therapy (GDMT)

This study will establish the safety and effectiveness of the SAPIEN M3 System in subjects with symptomatic, at least 3+ mitral regurgitation (MR) for whom commercially available surgical or transcatheter treatment options are deemed unsuitable. Following completion of enrollment, subjects will be eligible for enrollment in the continued access phase of the trial.

This study will evaluate the safety of the Cardiovalve Transfemoral Mitral Valve System with its associated procedure, and observe the device performance in reducing mitral regurgitation. Data collected in this clinical study will include 30-day safety and performance, and long-term clinical outcomes over a follow-up of 2 years.

Study to evaluate the safety and performance of the Innovalve mitral valve replacement system

A feasibility study to evaluate the effectiveness and safety of the SQ-Kyrin Transcatheter Edge-to-Edge Valve Repair System for the treatment of moderate-to-severe mitral regurgitation in patients with high surgical risk.

The surgical treatment of less than severe (≤2+/4+) functional tricuspid regurgitation (TR) in patient undergoing mitral valve surgery, is still controversial: some observational studies have suggested that performing tricuspid annuloplasty in patients undergoing mitral valve surgery with a dilated tricuspid annulus, and TR≤2+ may provide a clinical benefit, while in other observational studies such benefit has not been documented. The ESC Guidelines assign the class IIa recommendation for surgical treatment in patients with tricuspid regurgitation ≤2+ and a dilated annulus, if surgery is concomitant to the repair or replacement of the mitral valve. However the level of evidence C (expert opinion) confirms the absence of clear scientific evidence to support this recommendation. It is therefore very important to carry out randomized trials designed to really prove the supposed efficacy of prophylactic tricuspid annuloplasty, especially in patients with degenerative etiology where the data are particularly controversial. The aim of the study will be to establish the effectiveness of the tricuspid annuloplasty in the early stage of TR. The investigators enrolled patients with TR≤2+ and annular dilation undergoing mitral valve repair. Primary end-point will be the freedom from recurrence of TR≥3+ and from progression of 2 degrees of TR compared to pre-operative, at discharge and 12 months after surgery, assessment by transthoracic echocardiography. Secondary endpoints are to demonstrate the superiority of combined treatment (M & T Repair Group) compared to single treatment (Mitral-Only Group) at 5 and 10 years after surgery. This will be an experimental superiority, prospective, spontaneous, multicenter, randomized trial. Patients will be randomly assigned to two parallel arms with an allocation ratio 1:1 stratified by center, to receive mitral repair only (Mitral-Only group) or both mitral and tricuspid repair (M & T Repair group).

KALIOS is indicated for the surgical treatment of mitral regurgitation by mitral valve repair.It is intended for mitral valve repair using conventional open heart or minimally invasive techniques. The KALIOS device is an adjustable annuloplasty ring, to be implanted by open surgery, having a hollow structure that comprises a flat rigid ring surrounding a deformable cage. The unique feature of KALIOS is that its annular shape and dimension can be finely adjusted percutaneously by an external actuator (three-balloon catheter) independently in the three areas corresponding to P1, P2 and P3 The primary objective of this clinical investigation is to assess the safety and effectiveness of KALIOS for the surgical treatment of Mitral Regurgitation with optional intra-operative and/or post-operative adjustment(s) The secondary objectives are to investigate the effects of KALIOS for the surgical treatment of Mitral Regurgitation on cardiac function and on patient functional status This clinical trial is prospective, non-randomized, single arm, multicentric & international. Up to 100 patients are expected to be enrolled to obtain 62 evaluable patients at one year,presenting with primary (degenerative) or secondary (functional) mitral valve regurgitation and who are candidate to a mitral valve repair.

Mitral Touch System This device is designed to epicardially reshape the mitral valve annulus without the need for cardiopulmonary bypass (CPB) and open heart access (atriotomy), in patients with left ventricular dilation and ischemic or functional MR (mitral regurgitation (MR)).

Degenerative mitral regurgitation (MR) due to leaflet prolapse is frequent and can be surgically repaired in the vast majority of patients. Despite the efficacy of mitral valve repair, an ongoing international controversy exists regarding the need to perform early surgery in asymptomatic patients with severe MR and no sign of LV dysfunction in whom the probability of successful and durable repair is very high. In this group of patients, differing views of the risks of uncorrected severe MR exist: considered as benign by those supporting medical "watchful waiting" or associated with significant excess mortality/morbidity by those advocating early surgery. This controversy can only be resolved by a randomized controlled trial which is still lacking. The main objective is to demonstrate the superiority of early mitral valve repair in patients with asymptomatic severe MR due to leaflet prolapse compared to an initial conservative management in terms of all-cause death and cardiovascular morbidity during five years follow-up.

Prospective, controlled, multicenter clinical investigation with four trial cohorts: Randomized, Non-repairable, Severe Mitral Annular Calcification (MAC) and Severe Mitral Annular Calcification Continued Access Protocol (MAC CAP). Subjects in the Randomized cohort will be randomized in a 1:1 ratio to the trial device or to the MitraClip system. Subjects in the Non-repairable, Severe MAC, and Severe MAC CAP cohorts will receive the trial device. The objective of the Clinical Trial to Evaluate the Safety and Effectiveness of Using the Tendyne Transcatheter Mitral Valve System for the Treatment of Symptomatic Mitral Regurgitation (SUMMIT) is to evaluate the safety and effectiveness of the Tendyne Transcatheter Mitral Valve System for the treatment of patients with symptomatic, moderate-to-severe or severe mitral regurgitation or for patients with symptomatic mitral valve disease due to severe mitral annular calcification. This randomized controlled trial will provide the opportunity to evaluate the safety and clinical benefits of the Tendyne Transcatheter Mitral Valve System compared to the MitraClip System in patients with symptomatic, moderate-to-severe or severe mitral regurgitation, within approved MitraClip indications. In addition, the safety and effectiveness of the Tendyne Transcatheter Mitral Valve System will be evaluated in patients with severe mitral annular calcification who are at prohibitive risk for mitral valve surgery. Patients who are not suitable for mitral valve surgery for reasons other than severe mitral annular calcification and are also not suitable for transcatheter repair with MitraClip, will be enrolled in the Non-repairable cohort. Subjects will be seen at screening, pre- and post-procedure, discharge, 30 days, 3 months, 6 months, and annually through 5 years.
