Bilateral Coronary Artery to Pulmonary Artery Fistulae: A Very Rare Anomaly

Abstract

Coronary artery fistulas (CAFs) are a rare group of coronary anomalies which result in an abnormal connection between a coronary artery and either a cardiac chamber or any great vessel, most commonly pulmonary artery. They are mostly congenital but can be acquired and usually diagnosed incidentally. Although single vessel fistulas are far more common and have been reported routinely in literature, bilateral or multiple fistulas are extremely rare. Here, we describe a very unique case of bilateral coronary artery fistulas in a patient, with fortunately no significant hemodynamic consequences.
