Idiopathic Hypercalcemia and Supravalvular Aortic Stenosis

Abstract

A PECULIAR facies suggesting kinship has been found in some nonfamilial cases of supravalvular aortic stenosis in childhood.^{1 2 3 4 5} In addition, it has been recognized that infants with idiopathic hypercalcemia have a rather characteristic "elfin" facial appearance. Recently described are a group of older children with "aortic stenosis" and an "elfin" fades. An illness during infancy in each patient was suggestive of idiopathic hypercalcemia.² Their facies appeared identical to those of patients with supravalvular aortic stenosis described by others.^{1 , 3 , 4} It seems unlikely that this remarkable similarity is coincidental.Although an association between idiopathic hypercalcemia and supravalvular aortic stenosis has been alluded . . .
