Coronary artery aneurysms (CAA) are rare and life-threatening cardiovascular abnormalities. Multiple aneurysms and giant aneurysms are even rarer. The authors report a case of a giant CAA (7 cm) in a 62-year-old male patient with multiple cardiovascular risks. In fact, there were three adjacent aneurysms of the right coronary artery (RCA) that were connected to the cardiac chambers through two fistulas. Additionally, there was significant stenosis of the left anterior descending (LAD) at segment II. The patient underwent double coronary artery bypass grafting (RCA and LAD) and aneurysm repair under cardiopulmonary bypass. Despite a few early postoperative complications, the results in terms of myocardial revascularization were good, and the patient was discharged from the hospital on the 18th day postoperatively.
