A 63-year-old man developed acute congestive heart failure with orthopnea and was transferred to our institution. Aortography and transesophageal echocardiography demonstrated that the aortic valve was congenitally quadricuspid. In preoperative coronary angiography, the left anterior descending artery and the circumflex artery arose from the same orifice of the right coronary artery. So far as we know, quadricuspid aortic valve associated with a single coronary ostium is an extremely rare congenital cardiac anomaly combination. During aortic valve replacement for this particular case, antegrade cardioplegia including a selective coronary perfusion was considered unreliable, thus continuous retrograde blood cardioplegia was employed for intraoperative myocardial protection.
