A 40-year-old male underwent operation with a suspected diagnosis of a ruptured of Valsalva aneurysm and a bicuspid aortic valve. The aneurysm with an apical rupture protruded into the membranous septum, between the leaflets of the tricuspid valve. The aortic valve was bicuspid, with the aneurysm originating from the right sinus of Valsalva. We presume that the bicuspid aortic valve tends to cause the sinus of Valsalva aneurysm in point that each coronary sinus is given excessive pressure compared with that in the normal aortic valve. Rarity of the combined cases is possibly because the bicuspid aortic valve is frequent while the sinus of Valsalva aneurysm is rare in Western countries and vice versa in Japan.
