GIANT LEFT MAIN PSEUDOANEURYSM OBSTRUCTING THE LEFT ANTERIOR DESCENDING CORONARY-ARTERY DEMONSTRATED BY TRANSESOPHAGEAL ECHOCARDIOGRAPHY AND CORONARY ANGIOGRAPHY

Left main pseudoaneurysm is a rare angiographic finding in young adults. We describe a 23-year-old male who presented with an acute anterior wall myocardial infarction. Coronary angiography and transesophageal echocardiography reveal a huge aneurysm of the distal left main obstructing the left anterior descending artery (LAD), which was defined by history as a pseudoaneurysm. The pseudoaneurysm was successfully resected and mammary artery was used to repair the distal left main and to bypass the LAD. (C) 1993 Wiley-Liss, Inc.
