We report a case of a 74 old man presenting unstable angina and history of previous myocardial infarction. Coronary angiography showed significant stenoses of the left main and right coronary arteries and saccular aneurysm of the left anterior descending coronary artery. The patient underwent surgical treatment consisting in coronary artery bypass grafts and aneurysm resection. This procedure appears indicated, in author's opinion, when coronary aneurysm is saccular as in the described case.
