Ventricular Septal Defect and Left Ventricular Aneurysm

Late Occurrence as Complications of an Acute Myocardial Infarction

Abstract

Mechanical complications of acute myocardial infarction (AMI) such as a ventricular septal defect (VSD) usually occur within the first week. In the thrombolytic era, the incidence of a VSD has not increased, but has been reported to occur earlier than previously described. We report an unusual case of an elderly Caucasian female with an acute anterior wall myocardial infarction treated with thrombolytic therapy. Her AMI was complicated by pulmonary edema secondary to a VSD and a left ventricular aneurysm five weeks later. Prompt diagnosis, immediate surgical closure of the VSD, and aneurysmectomy resulted in her complete recovery.
