Acute Myocardial Infarction and Severe Prosthetic Dysfunction after Bentall Procedure

Introduction

Coronary artery anastomotic dehiscence is a rare complication following aortic procedures. A 59-year-old male previously underwent replacement of the ascending aorta and aortic valve because of ascending aorta aneurysm and severe aortic regurgitation. Eight years after the procedure, he presented with acute myocardial infarction. Transesophageal echocardiography (TEE) and coronary angiography revealed coronary artery dehiscence. This finding rarely occurs after a Bentall procedure; however, if it does, it usually occurs in the early postoperative period and is associated with an infectious etiology. In this case, coronary dehiscence presented with myocardial infarction years after the procedure and was first suspected after TEE.
