RESTOR-MV: Randomized Evaluation of a Surgical Treatment for Off-Pump Repair of the Mitral Valve

Inclusion Criteria: Grade 2, 3, or 4 functional mitral valve regurgitation per 2D echocardiography Patient undergoing concomitant coronary artery bypass graft surgery, either on-pump or off-pump Left ventricular ejection fraction greater than or equal to 25% Age between 18 and 80 years, inclusive Patient is willing and available to return for study follow up Ability of the patient or legal representative to understand and provide signed consent for participating in the study. Exclusion Criteria: Structural abnormality of the mitral valve (e.g. calcification or thickening of the valve leaflets, ruptured papillary muscle, ruptured chordae tendinae, mitral valve prolapse, mitral stenosis, etc.) Asymptomatic Grade 2 MR (those with NYHA Class < II AND LVEF > 40%) Organic valve disease resulting in insufficiency or stenosis of the aortic, pulmonary or tricuspid valve requiring surgical intervention Transmural myocardial infarction within 30 day period prior to surgical placement of Coapsys NYHA class IV Left ventricular end diastolic diameter > 7.0 cm Cardiac surgery on an emergency or salvage basis Left atrial or left ventricular thrombus Left ventricular aneurysm Previous mitral valve surgery or other previous cardiac surgery that would preclude proper placement of the Coapsys Chronic renal failure requiring dialysis Open chest surgery contraindication (e.g., acute respiratory distress, endocarditis, myocarditis, pericarditis) Active infection Life expectancy of less than 24 months due to conditions other than their cardiac status Participation in another investigational drug or device protocol Abnormal coronary or cardiac anatomy such that the device could not be placed without interfering with those anatomical structures.
