Aim of the study. To verify the impact of the etiology of mitral valve regurgitation on a 5-year outcome after repair and concomitant coronary artery bypass grafting (CABG).
Methods. One hundred and eleven consecutive patients (mean age of 69±8 years) who underwent mitral valve repair, 65 for ischemic and 46 for degenerative mitral regurgitation, and concomitant CABG, were retrospectively analyzed. The mean follow-up was 40±28 (9-104) months. Five-year survival (including operative mortality), and survival free from events (postoperative low output syndrome, progression of mitral regurgitation, onset or worsening of congestive heart failure, recurrence of myocardial infarction, and the need for mitral valve replacement) were analyzed.
Results. Compared with degenerative, ischemic mitral regurgitation was associated with a higher incidence of previous myocardial infarction (P
