Functional Mitral Regurgitation

A prospective, observational cohort study designed to identify clinical phenotypes and evaluate predictors \& outcomes of functional mitral and tricuspid valve regurgitation in patients with atrial fibrillation. Participant will under go: * Baseline echocardiography * Cpex Echocardiography * Blood test: BNP * 1 year follow up Echocardiography Participants will be stratified into three subgroups: * Atrial Functional MR * Atrial Functional TR * Mixed MR \& TR

The objective of this prospective, randomized, double- blinded (patient and assessors), sham-controlled clinical trial is to assess the safety and efficacy of the CMCS in treating heart failure with functional regurgitation (FMR).

This is a multi-center, prospective, observational study designed to evaluate the impact of LV myocardial fibrosis extent assessed by CMR on LV reverse remodeling and clinical outcomes post TEER. The target sample will be up to 125 patients enrolled to achieve 100 evaluable at 6 months of follow-up. Enrollment will occur at up to eight centers.

The goal of the current research is to develop personalized risk prediction for functional mitral regurgitation (FMR) patients through explainable unsupervised phenomapping enriched with advanced cardiac magnetic resonance (CMR) imaging biomarkers, and to determine the CMR predictors of reverse remodeling following modern therapies for FMR. The prospective study entails aiming to recruit 360 adult patients (ages \>18 years) with EF 10-50% and FMR RF\> 20%, who are clinically referred for CMR evaluation. Patients who enroll in our study will be referred for optimization of mGDMT and will undergo follow-up CMR studies at 6months. NICM patients who are fully medically optimized with significant FMR at the time of the baseline CMR and are referred for Mitraclip treatment will undergo follow-up CMR 6 months from Mitraclip intervention. NICM patients referred for mGDMT optimization, but have persistent or progressive FMR at the time of 6 month follow-up CMR and referred for Mitraclip therapy, will undergo a 2nd follow-up CMR 6 months from Mitraclip therapy.

The purpose of this study is to evaluate the safety and feasibility of the Bio Refine Coriofix System and determine if it might help in treatment of functional mitral regurgitation. The study will include patients with symptomatic secondary mitral regurgitation in whom mitral surgery cannot and/or will not be offered as a treatment option (the risk is prohibitive). Potential patients will be screened to confirm that all inclusion/exclusion criteria are met, with final eligibility confirmation on day of procedure. All enrolled subjects who went through the procedure will be followed during the procedure to hospital discharge. Additional follow up time points are scheduled at 30 days, 6 months and 12 months post procedure.

The investigation objective of this study is to evaluate the safety and effectiveness of the Transcatheter Mitral Valve Clip Delivery System and Steerable Guide Catheter in the population of FMR patients and the accessories devices when used in conjunction with the Transcatheter Mitral Valve Clip Delivery System and Steerable Guide Catheter.

Transcatheter edge-to-edge repair of the mitral valve (M-TEER) is a well-established endovascular treatment option for patients with severe mitral regurgitation who are at high risk for surgery-related complications. However, the procedure carries a risk of clinically overt strokes and imaging-detected brain lesions, which may potentially be mitigated through the use of cerebral protection devices. This prospective, multi-center, randomized, controlled study aims to assess the efficacy and safety of cerebral protection device, compared to a control group undergoing unprotected M-TEER.

To evaluate the safety and performance of the Mitral Touch System to treat mitral insufficiency in patients who are to undergo cardiac surgery with either a sternotomy or thoracotomy who present with moderate to severe ischemic or functional mitral regurgitation.

An early feasibility study to evaluate the safety and feasibility of the PLAR Implant and Delivery System to treat severe functional mitral regurgitation and to gather preliminary data on its performance thereby providing guidance for future clinical development. The study is a single-arm registry with the last follow-up visit at 5 years post-intervention. The study will enroll up to 10 patients at one (1) center in Brazil.
