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

To overcome the problem of stenting a growing vessel, intentional stent fracture (ISF) with ultrahigh-pressure (UHP) balloon has been introduced and applied in a limited number of patients. In piglet models, the ISF technique was associated with a significant incidence of complications, which were preventable (with the exception of stent fragment embolization) by performing pre-stenting before ISF.
