The incidence of ventricular subepicardial aneurysm following myocardial infarction is quite low. We report a case of subepicardial aneurysm that was diagnosed on postoperative pathohistologic examination. A 69-year-old man was admitted to our hospital because of left ventricular aneurysm following myocardial infarction. The patient had left main trunk disease, triple-vessel coronary artery desease and low output syndrome. Under cardiopulmonary bypass with the heart arrested, the aneurysm was resected and the defect was closed. The suture line was reinforced using Teflon felt and GRF glue. A saphenous vein graft was anastmosed to the left anterior descending artery. On pathohistologic examination, the wall of the aneurysm was found to be composed of fibrotic tissue, myocardial fibers, medium-sized pericardial arteries, epicardium and fibrin thrombi. We diagnosed this as subepicardial aneurysm.
