Abstract
Infective aneurysm showing dilatation of all three coronary sinuses of Valsalva due to infective endocarditis is extremely rare. We present the first report of such a case complicated by left single coronary artery. The patient was a 55-year-old man with a past history of untreated diabetes mellitus, cerebral infarction, aortic regurgitation and high-grade fever. He was admitted with a complaint of easy fatigability. In a treadmill exercise test, asymptomatic ischemic depression of the ST segment was observed. Two-dimensional echocardiography revealed marked dilatation of all three sinuses of Valsalva, and a mural thrombus within the dilated right sinus of Valsalva. On magnetic resonance imaging, an abnormal signal in the markedly dilated right sinus of Valsalva was revealed. Coronary arteriography showed left single coronary artery (L1 type by Sharbaugh's classification). The histopathological features of the affected aorta were thought to represent the healing stage of infective endocarditis. With regard to the myocardial ischemia in this patient, it was thought to have arisen mainly through aortic regurgitation and coronary atherosclerosis due to single coronary artery, and partly influenced by untreated diabetes mellitus.
