Papillary Fibroelastoma of Aortic and Mitral Valves Following Myectomy for Idiopathic Hypertrophic Subaortic Stenosis

Abstract

A 27-year-old woman who had previously undergone subaortic septal myectomy for idiopathic hypertrophic subaortic stenosis presented in severe congestive failure with echocardiographic and angiographic features of aortic valve "vegetations". At operation, papillary fibroelastomas of the aortic and mitral valves were found. The controversy surrounding the etiology of these "tumors" is discussed.
