We reported a rare case of aorto-left ventricular fistula with the unruptured aneurysm of the Valsalva sinus due to the infective endocarditis. Preoperatively trans-echocardiographic examination revealed the ruptured left sinus of Valsalva aneurysm protruded toward the left ventricule. Aorto-left ventricular fistula contiguous to the unruptured aneurysm of the right valsalva sinus, however, was detected at operation. Granulation tissue resembling healed infective vegetation was detected in the margin among the orifices of this fistula and Valsalva aneurysm. Pathological examination showed excessive accumulation of white blood cells, which suggested infective endocarditis.
