title: Congenital aortic valve anomaly. Aortic regurgitation with left coronary artery isolation.
abstract: A case is reported of aortic regurgitation resulting from a congenitally abnormal aortic valve. The left coronary cusp of the valve was small and adhered to the aortic wall, so that there was insufficient valve tissue to maintain diastolic valve competence. In addition, this rudimentary cusp completely occluded the left coronary ostium. The patient was treated successfully by valve replacement.
