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