Discrete subvalvular aortic stenosis in the Beckwith-Wiedemann syndrome.

Various congenital cardiac malformations have been described in patients with Beckwith-Wiedemann (BW) syndrome, including reversible obstructive subaortic stenosis in one patient. We herein present a case of a 2.5-year-old black boy with BW syndrome and discrete subvalvular aortic stenosis of the membraneous type. Such association of these two entities has previously not been documented.
