Active clinical trials for "Mitral Valve Insufficiency"

The timing of surgical intervention in asymptomatic patients with severe degenerative mitral regurgitation (MR) remains controversial. The benefit of early surgery has been suggested in prospective, observational studies, whereas a watchful waiting strategy seemed to be safe and effective in the other prospective study. The consensus guidelines for the performance of early surgery in asymptomatic patients with severe MR are different, reflecting controversy. Clinical outcome in asymptomatic patients with MR is poorly defined and it is important to identify high-risk patients in whom early surgery may be warranted. Thus, the investigators try to compare long-term outcomes of early surgery with those of a conventional-treatment strategy in a large prospective cohort of asymptomatic patients with severe degenerative MR using a propensity analysis, and to identify high-risk subgroups to whom early surgery is more beneficial.

This study is a continuation of two previous studies --- the Severe Ischemic Mitral Regurgitation (SMR) Trial (NCT00807040) and the Moderate Ischemic Mitral regurgitation (MMR) Trial (NCT00806988) --- to learn more about patients' health 5-10 years after their mitral valve surgeries. The investigators will collect long-term health information on SMR and MMR trial participants using electronic medical records, patient and/or family input, public records, and healthcare- and vital status-related databases.

The objective of the study is to evaluate the safety and feasibility of the ARTO System in patients with mitral valve regurgitation (MR) associated with congestive heart failure (CHF).

Functional Mitral regurgitation is a now well known entity due to tethering of the valve either mono-lateral, as happens in lateral myocardial infarction, or bilateral as happens in dilated cardiomyopathy. Treatment of this pathology, either conserving the valve and addressing regurgitation by mean of restrictive annuloplasty, or implanting a prosthesis remains controversial in terms of mid and long term benefit for the patient. The investigators propose a randomized controlled study to compare the efficacy of both technique in terms of mortality and freedom from reintervention.

This study will evaluate the efficacy and safety of angiotensin converting enzyme inhibition (ACE-I) therapy for the treatment of mitral regurgitation (MR).

Studying the effects of Trans-catheter Mitral Valve Repair (TMVr) on the hemodynamics and biomarkers in patients with severe mitral valve regurgitation.

The Cardioband Transcatheter System (Cardioband) is indicated for the treatment of secondary (functional) mitral regurgitation (FMR). The Cardioband is a transcatheter system, deployed on the beating heart through a transseptal approach. The Cardioband is deployed along the posterior annulus of the mitral valve (MV) and is adjusted under trans-esophageal guidance on the beating heart. A CE mark study with 30 subjects has been completed and documented reduction of severity of mitral regurgitation (MR) and improvement in 6- minute walk test in subjects with moderate to severe MR. Study objectives are to test the efficacy of the Cardioband in improving MR and heart failure symptoms in patients with symptomatic (New York Heart Association (NYHA) Class III-IVa), severe MR in the post-marketing setting, And to evaluate the safety of the Cardioband system in the post-marketing setting.

The purpose of this study is to determine whether intra- and postoperative use of the cardioPAT® cell saver decreases the need for allogenic red blood cell transfusion in patients, who undergo open heart surgery (with cardiopulmonary bypass) and preoperatively have an increased risk for bleeding.

The purpose of the trial is to demonstrate the safety and performance of the Medtentia Annuloplasty Ring (MAR) during mitral valve repair surgery. In addition, the trial aims to demonstrate that the MAR fulfills the requirements for mitral valve annuloplasty rings.

The purpose of this study is to compare early mitral valve repair versus a watchful waiting strategy in asymptomatic patients with severe organic mitral valve regurgitation and preserved left ventricular function.
