Coronary-Cameral Fistula and Coronary Ectasia as a Prelude to Ischemia in the Absence of Obstructive Disease

A coronary artery fistula is a communication between a coronary artery and a chamber of the heart (coronary-cameral fistula) or a segment of the systemic or pulmonary circulation (coronary arteriovenous fistula). Coronary artery fistulae account for 0.4% of congenital cardiac anomalies. 

Coronary ectasia (CAE) defined as 1.5 -2 fold luminal dilatation of the adjacent normal segment, believed to be a form of atherosclerotic process is reported in about 3-8% of patients undergoing coronary angiogram; may present alone or in combination with obstructive stenotic lesions. Imaging modalities that can assist in the diagnosis of a coronary fistula include echocardiography, cardiac catheterization and multi-detector row computed tomography.  Read more>>>>>>>>>>>
