COAPT: Use of the mitraclip system® in treating both high risk and prohibitive risk surgical candidates with moderate to severe, centralized mitral regurgitation.

Short Description: The purpose of the study is to evaluate the safety and effectiveness of the investigational MitraClip System in patients with moderate-to-severe or severe functional mitral regurgitation (FMR) who have been determined to be too high risk for mitral valve surgery. FMR occurs when the two leaflets of the heart's mitral valve do not close properly causing blood to leak backward with each heartbeat. Since some of the blood leaks backward, the heart has to pump more blood with each beat to push the same amount of blood forward. Patient eligibility is assessed based on TTE, TEE, diagnostic catheterization, and surgical consultation. The study is randomized on a 1:1 basis, with assignment to either a "control group" that will NOT receive the study device but rather continue with medical therapy only or a "treatment group" that will receive the device (and also continue with medical therapy). Up to 350 patients will participate in this study across North America and will follow-up for 5 years.
