Abstract
Most left ventricular aneurysms (LVA) develop in the atherosclerotic occlusive coronary artery disease following a
transmural myocardial infarction. However, occasionally, LVA associated with normal coronary artery was found as
well in dilated cardiomyopathy, hypertrophic cardiomyopathy, Chagas’s disease, sarcoidosis, chest trauma, and
congenital malformation. We report a 53-year-old male who had systolic heart failure owing to a posterior wall
aneurysm of the left ventricle, which was found unintentionally during echocardiographic examination. Subsequent
stress thallium scan revealed irreversible defects in the inferolateral wall and apex, and coronary angiography
showed normal coronary arteries. The patient remained well under medical control for a follow-up period of 40
months. Previously undiagnosed inferoposterior wall myocardial infarction caused by thromboembolism with
spontaneous reperfusion may be considered in this patient.
