Abstract

A 60-year-old male presented with sudden onset chest pain and pulmonary oedema. Investigation confirmed torrential aortic regurgitation of a bicuspid valve. At surgery a ruptured chordae tendineae was identified which had been supporting the left-right cusp commissure with loss of attachment to the aortic wall. This case demonstrates that chordae tendineae may be present as a supporting structure of the aortic valve, and rupture can be a rare cause of torrential aortic regurgitation, similar in pathogenesis to how it may be associated with acute severe mitral regurgitation.
