A Case of Double Right Coronary Artery with Arteriovenous Fisula

ABSTRACT

Double coronary artery with coronary arteriovenous fistula is a very unusual anomaly and has not been reported in Korea. Coronary arteriovenous fistula consists of communication between one of the coronary arteries and a cardiac chamber or vein. It generally drains into the right ventricle, right atrium, coronary sinus, or pulmonary artery. It is being diagnosed with increasing frequency with combined use of coronary angiography and contrast echocardiography. In the present case, coronary angiography showed double right coronary artery with separated ostia. We confirmed that one of them drained into right ventricular chamber by contrast echocardiography performed after intraaortic contrast injection.
