[Subvalvular aortic stenosis, dysmorphic familial syndrome and peripheral muscular disease].

Two related cases are reported, those of two sisters aged 7 and 13, who had an aortic subvalvular stenosis in the form of a fibro-muscular channel, associated with mitral incompetence, a triangular facies with a pointed chin, pinched lips, a divergent squint, hypertelorism, a mask-like face, normal intelligence, and a peripheral muscular disorder with arthrogriposis. The description of such a combination of malformations is original, and this is discussed.
