A 71-year-old male was referred to our hospital due to abnormality detected by a chest roentgenogram. He had no symptoms except for slight chest oppression. He was found to have a giant coronary aneurysm. It was originated from a coronary artery (left circum flex branch) left ventricular fistula. The orifice of this fistula to the left ventricle was also dilated and formed diverticulum. Ligation of the feeding coronary branch, closure of the aneurysmal fistula in the left ventricular wall and aneurysmectomy were performed under cardiopulmonary bypass. Postoperative course was uneventful. A giant aneurysm originated from a coronary-left ventricular fistula was considered to be very rare.
