Coronary arterial microfistulae: A CT coronary angiography perspective

Abstract 

Coronary arterial microfistulae are abnormal connections between one or multiple coronary arteries and any cardiac chamber, vein, or thoracic vessel. They comprise a subsection of coronary fistulas where the abnormal connections are diffuse, as opposed to the larger, more common single vessel varieties. Most of these anomalies are detected incidentally on catheter angiography; however, we present this anomaly as a case report from the perspective of CT coronary angiography.
