Key result
Percutaneous PA stenting linked to a ~37% reduction in pressure gradient at 7 years.
Why the study?
The long-term efficacy and safety of percutaneous stent implantation for residual pulmonary artery stenosis in pediatric patients after surgical repair of complicated congenital heart diseases is not well established.
Does percutaneous stent implantation improve long-term efficacy and safety in pediatric patients with residual pulmonary artery stenosis after surgical repair of complicated congenital heart diseases?
Cohort (n=41)

Li et al. (2025) conducted a cohort in Residual pulmonary artery stenosis after surgical repair of complicated congenital heart diseases (n=41). Percutaneous stent implantation vs. Pre-operative baseline was evaluated on Pressure gradient across the stenosis (mmHg) (p=<0.001). Percutaneous stent implantation for residual pulmonary artery stenosis significantly decreased the pressure gradient across the stenosis from 52.6 mmHg to 33.1 mmHg at a median follow-up of 7.1 years.
