ABSTRACT: Coronary artery fistula (CAF) is an anomaly making a coronary artery communicate with a heart cavity or a great vessel, thus bypassing the myocardialcapillary bed. CAFisfrequently diagnosed as an incidental finding. Herein, we present the case of a 4-year-old boy. He was referred for a pediatric cardiology assessment due toacontinuous murmur at the middle sternal border. Echocardiogram showed dilated left coronary artery and an abnormal diastolic flow in the right atrium. The right-sided chambers were slightly enlarged,but ventricular contractility was normal. CAF was suspected. Angiographyand CT confirmed the diagnosis of coronary fistula from the circumflex coronary artery to the right atrium. Successful transcatheter closure with anAmplatzer PiccoloOccluder was performed with complete occlusion.
