Purpose

Prospective, controlled, multicenter clinical investigation with three trial cohorts: Randomized, Non-Randomized, and Mitral Annular Calcification (MAC). Subjects in the Randomized cohort will be randomized in a 1:1 ratio to the trial device or to the MitraClip system. Subjects in the Non-Randomized and MAC cohorts will receive the trial device. The objective of the Clinical Trial to Evaluate the Safety and Effectiveness of Using the Tendyne Mitral Valve System for the Treatment of Symptomatic Mitral Regurgitation (SUMMIT) is to evaluate the safety and effectiveness of the Tendyne Mitral Valve System for the treatment of patients with symptomatic, moderate-to-severe or severe mitral regurgitation or for patients with symptomatic mitral valve disease due to severe mitral annular calcification. This randomized controlled trial will provide the opportunity to evaluate the safety and clinical benefits of the Tendyne Mitral Valve System compared to the MitraClip System in patients with symptomatic, moderate-to-severe or severe mitral regurgitation, within approved MitraClip indications. In addition, the safety and effectiveness of the Tendyne Mitral Valve System will be evaluated in patients with severe mitral annular calcification who are at prohibitive risk for mitral valve surgery. Patients who are not suitable for mitral valve surgery for reasons other than severe mitral annular calcification and are also not suitable for transcatheter repair with MitraClip, will be enrolled in the Non-randomized cohort. Subjects will be seen at screening, pre- and post-procedure, discharge, 30 days, 3 months, 6 months, and annually through 5 years.
