title: Aneurysmal coronary arteriovenous fistula closing with covered stent deployment: a case report and review of literature.
abstract: Coronary arteriovenous fistula (CAVF) is a rarely encountered congenital coronary anomaly, in which coronary artery blood flow bypasses the myocardial capillary network and usually drains to a heart chamber or great vessel. It is usually asymptomatic. However, the risk of symptoms and complications increases with age. High output heart failure, pulmonary hypertension, myocardial ischemia and infective endocarditis may complicate the course of this anomaly. The appearance, and even rupture, of a saccular aneurysm is one of the even rarer complications of CAVF. Here we describe a 57 year-old patient with incidental finding of an aneurysmal CAVF which was treated successfully using covered stent.
