title: Quadricuspid aortic valve--report of a case associated with severe aortic regurgitation and review of the literature.
abstract: A case of a 59-year-old woman who had a quadricuspid aortic valve associated with severe aortic regurgitation is reported herein. The anomaly was revealed by aortography, after which the incompetent valve was excised and replaced by a St. Jude Medical prosthesis. A quadricuspid aortic valve must be considered as a malformation which leads to severe valve failure in later life.
