Active clinical trials for "Mitral Valve Insufficiency"

Functional mitral regurgitation (FMR) is a common finding in patients with dilated cardiomyopathy and reduced left ventricular ejection fraction (LVEF). The presence of a relevant FMR (grade ≥2) is associated with a higher morbidity and mortality. Cardiac resynchronization therapy (CRT) has been shown to be effective in patients with dilated cardiomyopathy and reduced LVEF. In selected patients, CRT has been linked to clinical improvement and reduced mortality. Importantly, 38% of patients with clinical indication for CRT present moderate or severe (FMR). Although FMR might be reduced after CRT, the persistence of a relevant FMR (≥2) after CRT ranges between 40% and 50% and is an independent predictor of no clinical response. In these patients, surgical FMR correction is frequently turned down as a result of a high surgical risk. Percutaneous repair of the mitral valve with the MitraClip system has demonstrated promising results in patients with dilated cardiomyopathy and reduced LVEF5. In a cohort of patients with no response to CRT and FMR ≥2, Auricchio et al showed significant clinical improvement with LVEF recovery and reduction in left ventricle (LV) volumes after MitraClip. The absence of randomization, the retrospective nature of the study and the subsequent selection biases were however major limitations that impeded solid conclusions. The objective of the present study is to assess the efficacy and safety of the MitraClip system in non-responders to CRT and FMR ≥2.

This is a prospective, multi-center, single-arm study to evaluate the VenTouch System for treatment of moderate to moderate-severe functional mitral valve regurgitation [FMR].

The preclinical and clinical evidence of safety and efficacy with the BACE device (concept and feasibility) paved the way for the evaluation of the BACE device in this prospective, multi-center, single-arm, self-controlled study for safety and efficacy in the treatment of functional MR in a maximum of 60 adult subjects. The primary efficacy endpoint will be reduction of MR grade to 1+ or less from the baseline MR grade through the 6 month study period. Primary safety endpoint will be freedom from major device and surgery-related adverse events for the duration of the 6 month follow up period. Patients will be followed up to two years.

The main objective is to assess the effectiveness and safety of the MitralStitch repair system in patients with moderate to severe and severe mitral regurgitation.

This study evaluates the addition of transcatheter mitral valve repair with the MitraClip device to medical treatment in patients with heart failure and moderate functional mitral regurgitation to determine the impact of left ventricular remodelling and patients' functional capacity.

Aim of this prospective trial is to assess the hemodynamic effects of a MitraClip procedure caused iatrogenic arterial septal defect (iASD) and the functional changes after interventional iASD closure in a randomized setting.

Prospective, observational, multi-center trial in which patients with mitral regurgitation sufficient to merit mitral valve repair will receive a surgical transvalvular, intra-annular Mitral Bridge™ to reduce or eliminate mitral regurgitation.

Study to assess mitral valve therapy for advanced insufficiency of functional or ischemic origin in patients with moderate-to-severe mitral regurgitation (MR) of primarily functional pathology and reduced left ventricular function considered to be at high surgical risk

The purpose of this prospective, non-randomized, single-arm feasibility study is to evaluate safety and feasibility of the iCoapsys System in patients with functional mitral valve insufficiency caused by annular dilation and/or papillary muscle displacement.

The purpose of this study is to prospectively evaluate major and minor neurologic events in patients undergoing right mini-thoracotomy mitral valve surgery and to compare different aortic clamping techniques; specifically, the endoaortic balloon with retrograde perfusion (Endoreturn) and the transthoracic clamp with retrograde perfusion. Major neurologic events will be evaluate through standard neurologic evaluation; minor neurologic events will be evaluate through magnetic resonance (MR) assessment. The first aim of the study is to determine the number and impact of microembolic events during right mini-thoracotomy mitral valve surgery on clinical neurological status and on MR evaluation. The investigators also aim to determine if different techniques of aortic clamping may impact on early outcome. Study hypothesis: despite recent concerns arising about endoaortic balloon with retrograde perfusion, the investigators expect to show equivalence in term of safety and effectiveness of this technique compared with the transthoracic clamp in a selected population.
