Supravalvular Aortic Stenosis (Williams Syndrome) 1례

Abstract

Williams syndrome(Williams-Beuren Syndrome, Williams elfin facies syndrome) is a rare syndrome and this is the first case in Korea.

We experienced a case of Williams syndrome who was a 11 year old male child. He showed a characteristic facial appearance of this syndrome. A systolic thrill was palpable over the upper sternal borders and in the suprasternal notch. A Grade 3 (on the basis of 6) ejection systolic murmur was heard maximally over the right and left upper sternal borders and radiated over the entire precordium and into the neck. No manifestations of congestive cardiac failure were present. Pectus excavatum and inguinal hernia were observed. he also had mental retardation (IQ=66).

Diagnosis was established by angiocardiography, and also aided by EKG and phonocardiography.

A brief review of the literatures was done.
