title: [Quadricuspid Aortic Valve with Aortic Regurgitation;Report of a Case].
abstract: A 65-year-old woman was admitted due to electrocardiographic abnormality and exertional dyspnea. Transthoracic echocardiography revealed quadricuspid aortic valve malformation with severe aortic regurgitation. All 4 cusps were of equal size, and the quadricuspid valve was classified as type a by Hurwitz classification. We replaced it with an 18 mm mechanical valve and her postoperative course was uneventful.
