Abstract

A case of pediatric atrial fibrillation ablation resulting in unilateral pulmonary vein occlusion during longterm follow-up, HeartRhythm Case Reports (2022), doi: https://doi.org/10.1016/j.hrcr.2021.12.017. This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record.

Pulmonary Vein Intervention for Severe Pulmonary Vein Stenosis After Atrial Fibrillation Ablation ― A Retrospective Cohort Study ―

“…13-15 PVS after AF ablation has been reported, even in pediatric cases. 12 Younger patients generally have less advanced structural remodeling. 13, 14 These data suggest that patients with less advanced structural remodeling of the atria and PVs are more likely to develop PVS, possibly due to smaller PV diameters, a higher amount of myocardial mass, 13,14 more severe inflammation, and the subsequent fibrotic process of the ablation lesions, resulting in shrinkage of the PV.…”
