Coronary artery fistula is an unusual congenital anomaly, particularly in association with coronary aneurysm. In the present case, a right coronary fistula leading to the right atrium was associated with a giant coronary aneurysm. There have only been 3 such cases reported in the literature. Since both the aneurysm and the fistula were completely thrombosed, no heart murmur was detected and the patient was initially diagnosed as having an intracardiac tumor by echocardiography.
