Intentional Stent Fracture to Accommodate Growth After Coarctation Stenting in an 860-g Neonate.

ABSTRACT:

Background

Congenital aortic coarctation in neonates and children can be managed with transcatheter stent implantation, but this approach raises the issue of how to accommodate the fixed stent structure within the growing vessel.

Case summary

A 15-month-old boy, born prematurely with critical aortic coarctation, was treated at 1 week of age with the implantation of a coronary stent. Subsequently, multiple stent dilatations were needed to adapt it to the growing aortic vessel. At 3 months the patient underwent balloon dilation with the simultaneous implantation of a second stent, and after 1 year an ultra-high-pressure balloon dilatation with intentional fracture of the coronary stent was performed.

Discussion

To overcome the problem of stenting a growing vessel, inten
