title: [A case of quadricuspid aortic valve associated with coronary artery disease].
abstract: A 65-year-old man with aortic regurgitation was found to have a quadricuspid aortic valve. Surgical correction consisted of aortic valve replacement with a 21 mm Hyper dynamic plus St. Jude Medical valve and coronary revascularization of LAD and the first diagonal branch. During the operation, a quadricuspid aortic valve with 1 smaller and 3 larger cusps and normal coronary orifice were noticed. Accurate information by the transesophageal echo proved to be quite valuable. Our case is one of 43 cases which have been reported in Japan.
