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

A coronary artery fistula is a communication between a coronary artery and a chamber of the heart (coronary-cameral fistula). Coronary ectasia is the luminal dilatation of the adjacent normal segment, believed to be a form of atherosclerotic process, and is reported in about 3-8% of patients undergoing coronary angiogram. Coronary-cameral fistula and coronary ectasia, when existing concurrently, may present as a prelude to ischemia even in the absence of obstructive disease. We report here one such case seen in an elderly female. She presented with recurrent episodes of angina despite the absence of occlusive coronary artery disease. We also review the literature.
