Circumflex coronary artery fistulae with myocardial bridging in the right coronary artery: Case report

Abstract

Congenital coronary fistula is a rare heart anomaly, which is a conection between a coronary artery and a cardiac chamber. Most such fistulas drain into the right side of the heart including the pulmonary artery. Congenital left sided fistula is even more uncommon. Coronary artery bridging has been recognized for a long time and shows an almost uniform predilection for the left coronary artery distribution. Most ofthese patients are asymptomatic; however, myocardial infarction, congestive heart failure, infective endocarditis, arrhythmias or rupture of the aneurismal involved vessel may occur. Herein, we report an unusual case of circumflex coronary artery fistula in association with myocardial bridging in the right coronary artery distribution. Copyright ©2010 by Tükiye Klinikleri.
