Key result
Stent implantation for pediatric pulmonary vein stenosis significantly increased the mean minimal lesion diameter from 2.3 mm to 5.1 mm (p<0.01), though restenosis frequently occurred requiring redilatation.
Why the study?
Does stent implantation and subsequent redilatation improve lesion diameter and pressure gradient in pediatric patients with pulmonary vein stenosis?
Population
4 pediatric patients with 7 stenotic lesions of the pulmonary vein (PV)
Design
Case_series
Follow-up
up to 20 months

Stenting may acutely relieve pediatric pulmonary vein stenosis; leaves open durability, redilatation protocols, and need for prospective data.

Does stent implantation and subsequent redilatation improve lesion diameter and pressure gradient in pediatric patients with pulmonary vein stenosis?
Absolute Event Rate: 5.1% vs 2.3%
p-value: p=<0.01
Stent implantation followed by aggressive redilatation may be an effective strategy for managing pulmonary vein stenosis in pediatric patients, despite a high initial restenosis rate.
Tomita et al. (2003) conducted an observational in Pulmonary vein stenosis (n=4). Stent implantation and redilatation vs. Baseline (pre-stenting) was evaluated on Minimal diameter of the lesions (p=<0.01). Stent implantation for pediatric pulmonary vein stenosis significantly increased the mean minimal lesion diameter from 2.3 mm to 5.1 mm (p<0.01), though restenosis frequently occurred requiring redilatation.
