Late (>or=6 years) results of combined coronary artery bypass grafting and mitral valve replacement for severe mitral regurgitation secondary to acute myocardial infarction.
Analysis of outcomes in 31 patients who had combined mitral valve replacement (MVR) and coronary artery bypass grafting (CABG) for ischemic mitral regurgitation (MR) disclosed that 12 patients had MR because of papillary muscle rupture and that 19 patients had MR because of papillary muscle necrosis or fibrosis without rupture. Of the 12 patients with rupture, 6 died within 2 months of operation and the other 6 lived >or=6 years postoperatively; of the 19 patients without rupture, none died within 2 months of operation and 11 (58%) lived at least 6 years.
