Stent implantation completely abolished severe aortic coarctation in a 48-day-old infant after a Norwood operation, with autopsy confirming wide patency at 62 days.
Case Report (n=1)
Transcatheter stent implantation can effectively relieve severe aortic coarctation in early infancy following a Norwood operation, maintaining patency even if overall clinical outcomes remain challenging.
Stent relief of post-Norwood coarctation appears feasible in early infancy; extends sparse case experience but leaves open durability and survival impact.
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.

Tomita et al. (2001) conducted a case report in Severe aortic coarctation complicating the Norwood operation (n=1). Stent implantation was evaluated on Abolition of coarctation and stent patency. Stent implantation completely abolished severe aortic coarctation in a 48-day-old infant after a Norwood operation, with autopsy confirming wide patency at 62 days.
