Key result
RVOT stent implantation in children with obstructed RVOTs resulted in 66% requiring subsequent pulmonary valve replacement, with freedom from replacement of 91%, 51%, and 23% at 1, 5, and 10 years.
Why the study?
The optimal management pathway for the dysfunctional right ventricular outflow tract is uncertain in an era of rapidly progressing transcatheter pulmonary valve technology.
Does endovascular stent implantation delay subsequent pulmonary valve replacement in children with postoperative right ventricular outflow tract obstruction?

Does endovascular stent implantation delay subsequent pulmonary valve replacement in children with postoperative right ventricular outflow tract obstruction?
Endovascular stent implantation for postoperative RVOT obstruction effectively prolongs conduit longevity and delays the need for subsequent pulmonary valve replacement in children.

RVOT stenting was associated with hemodynamic improvement in children; leaves open optimal timing versus transcatheter valves in this era.
Kang et al. (2021) conducted a cohort in Obstructed right ventricular outflow tract (RVOT) (n=151). RVOT stent implantation vs. Children without stent palliation (with RV-to-PA conduits) was evaluated on Subsequent pulmonary valve replacement (PVR). RVOT stent implantation in children with obstructed RVOTs resulted in 66% requiring subsequent pulmonary valve replacement, with freedom from replacement of 91%, 51%, and 23% at 1, 5, and 10 years.
