[Ruptured aneurysms of sinus of Valsalva with bicuspid aortic valve--a case report of an aged patient (72 years old)].

A 72-year-old man with ruptured aneurysms of the sinus of Valsalva and a bicuspid aortic valve was operated. Ruptured aneurysms were found in the noncoronary sinus region, and they were opened to the commissure between the anterior cusp and septal cusp of the tricuspid valve. The tissue around the aneurysm was very weak, so closure of the ruptured hole was carried out from the inside of both aorta and right atrium. Ruptured aneurysm of Valsalva is very rare in a aged patient. In this case, it is considered that the bicuspid aortic valve associated with malformations of the aortic cusp caused a weakness of the sinus wall, and this region gradually became aneurysmal.
