Aneurysms of the left main coronary artery are rare and their optimal treatments remain unknown. A 64-year-old man without any symptoms was referred to our department for suspected coronary aneurysm. Transthoracic echocardiography demonstrated an aneurysm of the left main coronary artery. On transesophageal echocardiography, the thrombus was suspected inside and severe ostial stenosis of the left coronary artery was highly suspected due to the accelerated flow velocity. Multidetector computed tomography demonstrated the aneurysm as being 37 mm in diameter with significant stenosis at both left coronary arteries, more clearly than coronary angiography. Because of its size and coexisting coronary artery disease, surgical closure of the aneurysm and coronary artery bypasses were performed. Echocardiography and coronary computed tomography could help in the diagnosis and the therapeutic decision in the case of left main coronary artery aneurysm before coronary angiography.
