Left main coronary artery aneurysms are very rare and are incidentally encountered in about 0.1% of patients undergoing angiography. Atherosclerosis represents the main cause of this aneurysm in adult patients. Here, the author presents a case of a 58-year-old female with a history of hypertension and diabetes who had a Canadian Cardiovascular Society Grade II–III angina for the past 6 months. Selective coronary angiography revealed a large aneurysm involving the left main coronary artery (measuring 2 cm × 3 cm) with extensive coronary calcifications, ectatic proximal left circumflex followed by 80% stenotic lesion with normal left anterior descending and right coronary artery. The patient was managed with coronary artery bypass grafting along with ligation of the aneurysm. At the 3-month follow-up, the patient was asymptomatic. Therefore, distal coronary artery bypass surgery represents one of the therapeutic options and was safe and effective in our case.
