?Adults from 18 to 80 years of age, inclusive; either gender
?Symptomatic functional MR of grade moderate to severe (2 to 4 as per the ACC and AHA 2006 Classification of Mitral regurgitation evaluation NYHA Class II to IV
?LVEF 25%-50%
?Normal mitral valve leaflets
?Subject is willing and available to return for study follow up
?Surgical approach is the treatment option
?Ability of the subject or legal representative to understand and provide signed consent for participating in the study
?Subjects will be excluded if they meet any of the following criteria
?Known hypersensitivity or allergy to the device materials
?History or presence of rheumatic heart disease
?Structural abnormality of the mitral valve (e.g. flail leaflets, ruptured or elongated chordae, prolapsed valve, perforated valve leaflets)
?Severe pulmonary hypertension, defined by pulmonary artery systolic (PAS) pressure greater than or equal to 60 mm Hg
?Severe diastolic dysfunction of left ventricle on ECHO [restrictive filling pattern, characterized by E>> A, decreased IVRT, and decreased DT as seen with restrictive cardiomyopathies with LV ejection fractions of > 40%)
?Transmural myocardial infarction [MI] with in 30 days of enrollment in the study; non ST segment elevation MI within 7days of enrollment in the study
?Currently enrolled in another investigational drug or device study
?Subjects with heart size outside of offered BACE device size ranges [25 to 41 cm; correlate to pre-op measurement end diastolic dimension]
?Previous mitral valve surgery or other previous cardiac surgery that would preclude proper placement of the BACE
?Abnormal coronary or cardiac anatomy such that the device could not be placed without interfering with those anatomical structures
?Abnormalities in the mitral valve leaflets that would necessitate mitral valve reconstruction or replacement
?Prior Coronary Artery Bypass Graft (CABG) surgery
?Acute active infection
?Active peptic ulcer
?History of IV drug abuse
?Chronic renal failure requiring dialysis
?Creatinine > 2.5 mg/dL
?Open chest surgery contraindication [e.g., acute respiratory distress, endocarditis, myocarditis, pericarditis]
?Immune suppression therapy
?Subjects with chronic connective tissue disease
?Investigator judgment that body habitus or sternal anatomy precludes pericardial access
?Females who are pregnant or lactating
?Life expectancy of less than 12 months due to conditions other than cardiac status
