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.
