Supravalvular aortic stenosis is frequently associated with other congenital abnormalities such as pulmonary artery branch stenosis, unusual facies, retarded physical development, abnormal dentition, and mental retardation. Stenosis of the origins of the brachiocephalic vessels may be found in a significant percentage of cases. Its presence should be suspected when asymmetrical pulses or blood pressures in the upper extremities are found on physical examination, and may be verified by thoracic aortography.
Among the 4 new cases of supravalvular aortic stenosis reported herein, 3 had brachiocephalic vessel stenosis. All were diagnosed by roentgen contrast study and pressure measurements, with surgical confirmation and successful surgical therapy in 3.
