[Surgical repair of a subepicardial left ventricular aneurysm in a kidney transplant recipient; report of a case].

A 51-year-old man of the kidney transplant recipient was admitted to our hospital with acute myocardial infarction. Transthoracic echocardiography revealed a subepicardial left ventricular aneurysm that had increased in its size gradually. The operation was performed at 43rd days after myocardial infarction. Subepicardial aneurysm was seen on the posterior wall of the left ventricle. The orifice of the aneurysm was closed with expanded polytetrafluoroethylene (ePTFE) patch. The postoperative course was uneventful in spite of immunosuppressive therapy with ciclosporin. Surgical repair of a subepicardial aneurysm is recommended because of its high rupture rate.
