Stent implantation for aortic coarctation complicating the Norwood operation in a 48-day-old baby.

A female infant developed severe aortic coarctation 42 days after a Norwood operation. Balloon dilatation was ineffective due to rapid recoil of the narrowing, but stent implantation completely abolished coarctation. Although the patient died because of low systemic output with high pulmonary flow 62 days after stent implantation, an autopsy showed that the implanted stent was widely patent without any restenosis. Transcatheter stent implantation should be considered for coarctation in selected situations even in early infancy.
