title: Duplication of the right atrioventricular orifice in a patient with common atrium and mitral cleft.
abstract: The following case involved duplication of the right atrioventricular valve in a patient with a common atrium. The accessory orifice, formed by two fine leaflets, connected the right atrium with the right ventricular outflow tract and had no subvalvular apparatus. Successful surgical correction was accomplished under standard cardiopulmonary bypass.
