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.
一名40岁男性因疑似瓦氏窦瘤破裂和二叶式主动脉瓣而接受手术。顶端破裂的瘤体突入三尖瓣叶之间的膜性间隔。主动脉瓣为二叶式，瘤体起源于瓦氏窦右窦。我们推测，二叶式主动脉瓣倾向于导致瓦氏窦瘤，因为与正常主动脉瓣相比，每个冠状窦承受的压力过大。这种合并病例的罕见性可能是因为在西方国家二叶式主动脉瓣常见而瓦氏窦瘤罕见，而在日本则相反。
