Successful transcatheter closure of coronary artery fistula in a patient with anomalous aortic origin of the left main coronary artery from the right aortic sinus

Abstract Transcatheter closure is an established method to treat coronary artery fistula (CAF). We present transcatheter closure in a 6-year-old girl with CAF and anomalous aortic origin of the left main coronary artery from the right aortic sinus. The CAF originated from the left coronary artery (LCA), coursed through the interventricular septum (intraseptal course) with prominent dilation, and drained into the right ventricular outflow tract. She underwent transcatheter closure and was in a stable condition at the 3-year follow-up with regression of the dilated portion of the intraseptal-type LCA. Hence, transcatheter closure of CAF is feasible in patients with anomalous origins of coronary arteries.
