Mitral Insufficiency Due to Ruptured Chordae Tendineae Simulating Aortic Stenosis

Abstract

THE case reported below illustrates two interesting and unusual phenomena. The first is the production of the physical signs and phonocardiographic evidence of aortic stenosis in a patient with mitral insufficiency but without disease of the aortic valve.
