BACKGROUND: Giant coronary artery aneurysm (GCAA) is a rare disease, with an incidence of 0.02% in the general population. GCAA is defined as when the diameter of the coronary artery is more than 4 times the adjacent part or more than 8 mm. There are several causes of GCAA, with atherosclerosis being the most common. Patients with giant coronary artery aneurysms can be asymptomatic or develop chest pain, dyspnea, and palpitations. Complications of GCCA include myocardial infarction, thrombosis, and sudden death, so early treatment is necessary to prevent mortality. There is no standard surgical approach for a giant coronary artery aneurysm.
CASE REPORT: A 64-year-old man with hypertension, opium addiction, morbid obesity (body weight 151 kg and BMI 46), and benign prostate hyperplasia presented with a giant coronary aneurysm in coronary angiography. The patient underwent cardiac surgery, and a 42-mm coronary aneurysm was detected. The aneurysm had many orifices that opened to the left main coronary artery, left circumflex artery, LAD, the diagonal branch of the LAD, and the septal branch of the LAD. Aneurysmectomy and coronary artery bypass graft were successfully performed.
CONCLUSIONS: Giant coronary artery aneurysms are rare. Patients with giant coronary artery aneurysms may experience sudden death due to myocardial infarction and other cardiovascular complications due to ischemia. Because it is rare, there is no standard surgical approach for a giant coronary artery aneurysm. Further studies need to focus on standardized surgical management of patients with giant coronary artery aneurysms.
