[Aortic regurgitation due to quadricuspid aortic valve; report of a case].
A 66-year-old man was referred to our hospital for surgical treatment for aortic regurgitation. Transthoracic echocardiography revealed the diagnosis of aortic regurgitation due to quadricuspid aortic valve. During operation, we confirmed that the aortic valve consisted of 4 leaflets with almost same size (Hurwitz and Roberts classification type A). We performed valve replacement because each leaflet has degenerative change. The patient's postoperative course was uneventful and discharged the hospital without complications. Congenital quadricuspid aortic valves are rare, and patients with this disease are frequently operated because of aortic regurgitation. Presently, common operative procedure is aortic valve replacement, although in the future valvuloplasty should be investigated.
