title: [Mitral valve replacement and coronary artery bypass grafting for postinfarction mitral papillary muscle rupture].
abstract: A 79-year-old man was admitted to our hospital with heart failure following acute inferior myocardial infarction. An echocardiogram demonstrated severe mitral insufficiency, and coronary arteriography revealed double vesel disease. Following diagnosis of ischemic papillary muscle dysfunction, PTCA was performed, but the mitral insufficiency was not eliminated. Follow-up echocardiography disclosed rupture of the posterior papillary muscle. He underwent surgery on the 30th day after onset of acute myocardial infarction. Partial rupture of the posterior papillary muscle was found at surgery, and mitral valve replacement and single coronary artery bypass to Lcx were performed. His postoperative course was uneventful, and he was discharged on the 46th day after operation.
