A 59-year-old man with acute mitral regurgitation due to papillary muscle rupture after myocardial infarction was admitted to our hospital. He underwent emergent mitral valve replacement with a mechanical valve by median sternotomy. Although postoperative echocardiography showed no sign of a ventricular aneurysm, echocardiography performed 5 weeks after the surgery showed enlarging left ventricular pseudoaneurysm of the inferior to the posterior cardiac wall. He underwent dacron patch closure of the orifice by fifth intercostal left thoracotomy. The postoperative course was uneventful and he was discharged on postoperative day 10. The patient was successfully treated for two life-threatening complications occurring subsequently after myocardial infarction.
