Brief Summary
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.
Following completion of enrollment, subjects will be eligible for enrollment in the continued access phase of the trial.

Primary Outcomes
Outcome Description
Number of subjects with death and/or heart failure rehospitalization
Outcome Measure
Non-hierarchical composite of death and heart failure rehospitalization
Outcome Time Frame
1 year
Secondary Outcomes
Outcome Description
New York Heart Association (NYHA) functional classification of heart failure is based on how much a patient is limited during physical activity. The rating ranges from I-IV. I = no limitations of physical activity; II = slight limitations of physical activity, ordinary physical activity results in fatigue, palpitation, shortness of breath; III = marked limitations of physical activity, less than ordinary activity causes fatigue, palpitation, or shortness of breath; IV = unable to carry on any physical activity without discomfort, symptoms of heart failure at rest.
Outcome Time Frame
1 year
Outcome Measure
Improvement in NYHA functional class compared to baseline
Outcome Description
The Kansas City Cardiomyopathy Questionnaire (KCCQ) is a 23-item, self-administered instrument that quantifies physical function, symptoms (frequency, severity and recent change), social function, self-efficacy and knowledge, and quality of life. An overall summary score can be derived from the physical function, symptom (frequency and severity), social function and quality of life domains. Scores are transformed to a range of 0-100, in which higher scores reflect better health status.
Outcome Time Frame
1 year
Outcome Measure
