EVEREST II Randomized Controlled Trial (RCT) is a prospective, multi-center, randomized study of the MitraClip® System in the treatment of mitral valve regurgitation, randomizing patients to MitraClip or mitral valve surgery. The EVEREST II High Risk Registry (HRR) study is a prospective multi-center study of the MitraClip System for the treatment of mitral valve regurgitation in high surgical risk patients. Enrollment in the RCT and HRR is closed. A continued access prospective, multi-center study (REALISM) of the MitraClip System in a surgical population (non-high risk arm) and a high surgical risk population (high risk arm) is ongoing. Enrollment in the non-high risk arm of REALISM is closed. Enrollment in the high risk arm of REALISM is ongoing. Patients enrolled in EVEREST II undergo 30-day, 6-month, 12-month, 18-month and 24-month clinical and echocardiographic follow-up, and then annually for 5 years.

Key Inclusion/Exclusion Criteria: Patients with Grade 3 (moderate to severe) or Grade 4 (severe) mitral regurgitation (MR) based on American Society of Echocardiography guidelines: - Are 18 years or older. - Symptomatic - If asymptomatic, must have new onset of atrial fibrillation, pulmonary hypertension, or evidence of left ventricular dysfunction - Are candidates for mitral valve surgery - Are candidates for transseptal catheterization - Primary regurgitant jet must originate from malcoaptation of the A2 and P2 scallops of the mitral valve - Appropriate valve anatomy for MitraClip - Does not need other cardiac surgery or any emergency surgery - Did not experience myocardial infarction in prior 12 weeks or endovascular procedure in prior 30 days - Mitral valve orifice area = 4 cm2 - Do not have renal insufficiency - Echocardiographic evidence of intracardiac mass, thrombus or vegetation |

| Secondary | Short Form (SF)-36 Quality of Life Questionnaire. | The SF-36 is a multidimensional, patient-reported survey containing 36 questions on a 0-100 scale measuring physical (Physical Component Score) & mental health status (Mental Component Score) in relation to 8 health concepts: physical functioning, role limitations due to physical or emotional health, bodily pain, general health perceptions, vitality, social functioning, & general mental health. Responses to each of the SF-36 items are scored and expressed as a score on a 0-100 scale (0% in a domain represents the poorest possible QOL&100% indicates full QOL).Higher scores represent better self-perceived health. The physical & mental functions were assessed by the Physical Component Summary (PCS) score & Mental Component Summary (MCS) score. Normal PCS and MCS scores vary depending on the demographics of the population studied. The PCS&MCS norms for 65-75 year old are 44 & 52, respectively while the norms for CHF population are 31 & 46, respectively. |
