[A rare cause of pure isolated chronic aortic insufficiency: congenital quadricuspid aortic valve. Apropos of 2 cases]

Abstract

The authors report two new cases of congenital quadricuspid aortic valve complicated by pure, severe, chronic, aortic regurgitation. This abnormality was diagnosed fortuitously at transoesophageal echocardiography in one case and at aortography in the other, and confirmed at surgery. This congenital abnormality was associated with superior displacement of the left coronary ostium.
