Sliding Aortoplasty for Severe Supravalvular Aortic Stenosis After the Lecompte Procedure.

This report describes the case of a 3-year-old boy with supravalvular aortic stenosis after an arterial switch operation in whom the stenosis was successfully repaired using an ascending sliding arch aortoplasty without using a patch. Because patches were avoided, growth of the surgical site is expected. Ascending sliding arch aortoplasty and longitudinal expansion of the pulmonary bifurcation are useful for relieving stenosis and preventing supravalvular aortic stenosis recurrence after an arterial switch operation.
