Abstract
Neoaortic root dilation is inevitable in the years after an arterial switch operation, not uncommonly leading to neoaortic valve insufficiency that requires reoperation. Here we present a bicuspidization repair technique for addressing such neoaortic valve insufficiency in a child with the 1L 2RCx coronary pattern who underwent the arterial switch operation as a neonate for dextro-transposition of the great arteries that has good short-term outcomes thus far.
