Abstract
Unruptured sinus of Valsalva aneurysm is a rare anomaly which may be acquired or congenital. We describe a case of a 64 year old man with aneurysms (left : 31 mm, non : 21 mm) of the coronary sinus. The Bentall operation was successfully performed and his postoperative course was uneventful. The histopathology of the aortic wall showed Takayasu's arteritis. Bentall surgery is a good choice for multiple aneurysms of the Valsalva sinus with aortitis.
