Abstract
Congenital anomalies of the aortic valve represent a common malformation. Infrequently, a dysplastic aortic valve leaflet causes a severe coronary artery anomaly. Here, the case is reported of a malformed aortic valve in which the left rudimentary cusp occluded the left coronary ostium. At surgery the left coronary ostium was completely freed from the anomalous valvular tissue, a Konno operation was performed, and a 19 mm St. Jude Medical mechanical prosthesis was implanted. To date, very few reports have made of this rare malformation; moreover, to the present authors' knowledge this is the only case to have been treated.
