Comparing early mitral valve repair to watchful waiting for asymptomatic severe mitral regurgitation
Official title: Randomized Comparison of Early Mitral ValvE Repair Versus Watchful Waiting for Asymptomatic SEvere Degenerative Mitral Regurgitation Due to Leaflet Prolapse
Run by Centre Hospitalier Universitaire, Amiens · NCT03389542 · Data updated 2026-11-12
This study is testing if early surgery for the mitral valve can help people with severe mitral regurgitation live longer and healthier compared to just keeping an eye on their condition.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include asymptomatic individuals with severe degenerative mitral regurgitation and preserved left ventricular function.
✕Probably not a fit
Patients with significant comorbidities, prior cardiac surgeries, or those with symptomatic mitral regurgitation may not benefit from this study.

What this trial studies
This clinical trial aims to compare the outcomes of early surgical repair of the mitral valve in asymptomatic patients with severe degenerative mitral regurgitation against a conservative management approach known as watchful waiting. Patients in the experimental group will undergo surgery within three months of randomization, while those in the control group will be monitored with regular clinical interviews and echocardiograms. The study seeks to determine whether early intervention can reduce all-cause mortality and cardiovascular morbidity compared to conservative management. Follow-up assessments will occur at discharge, six months, and annually thereafter.
Why it matters
Potential benefit: If successful, this study could provide evidence supporting early surgical intervention, potentially improving survival and quality of life for patients with severe mitral regurgitation.
How similar studies have gone: While there is ongoing debate regarding the timing of surgery for asymptomatic patients, this trial addresses a gap in existing research, making it a novel approach.
