title: Congenital quadricuspid aortic valve with displacement of the right coronary orifice.
abstract: To date only five patients have undergone surgery for severe incompetence due to quadricuspid aortic valve (5-9). This report describes a new case of congenital quadricuspid aortic valve with severe regurgitation and associated displacement of the right coronary orifice, in which the abnormal valve was excised and replaced by a Björk-Shiley tilting disc valve prosthesis.
