Percutaneous or Surgical Repair In Mitral Prolapse And Regurgitation for ≥60 Year-olds (PRIMARY)

The patient population for this trial consists of adults with severe, primary degenerative MR for whom the local heart team has verified that an indication for MV intervention is present and for whom both transcatheter edge-to-edge and surgical repair strategies are anatomically feasible. Specific inclusion and exclusion criteria are listed below. All patients who meet eligibility criteria will be included in the study regardless of gender, race, or ethnicity. Inclusion Criteria: * Adult patients ≥60 years with moderately-severe or severe (3+ or 4+/4+) primary degenerative (Carpentier type II) MR defined by transthoracic echocardiography * Clinical indication for MV intervention and anatomic candidate for both surgical MV repair and transcatheter edge-to-edge repair (TEER) per local heart team assessment with central eligibility committee verification * Patients across the surgical risk spectrum (low, intermediate, and high risk) depending on local heart team assessment and central eligibility committee verification (see ACC/AHA 2020 guidelines for the management of patients with valvular heart disease) * Patients with AF who meet an indication for a concomitant ablation procedure be included provided the local heart team and central eligibility committee decide they are eligible for both catheter-based and surgical ablation. * Ability to perform 6-minute walk test (6MWT) and complete Kansas City Cardiomyopathy Questionnaire (KCCQ) instrument Exclusion Criteria: * Non-deg…
