May warrant targeted surveillance in native non-calcified RVOTs; extends risk-factor data but leaves open prospective validation.
What are the incidence and risk factors for stent fracture after percutaneous pulmonary valve implantation?
Stent fracture is a common complication after percutaneous pulmonary valve implantation (21.1%), particularly in native, non-calcified RVOTs with valve recoil, but can be managed with systematic surveillance and anticipatory strategies.
Nordmeyer et al. (2007) studied this question.
