摘　　要：Coronary artery fistula (CAF) is an anomaly making a coronary artery communicate with a heart cavity or a great vessel, thus bypassing the myocardial capillary bed. CAF is frequently 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 to a continuous 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. Angiography and CT confirmed the diagnosis of coronary fistula from the circumflex coronary artery to the right atrium. Successful transcatheter closure with an Amplatzer PiccoloOccluder was performed with complete occlusion.Coronary artery fistula (CAF) is an anomaly making a coronary artery communicate with a heart cavity or a great vessel, thus bypassing the myocardial capillary bed.
