Key result
Pulmonary vein stenosis after initial electrical isolation did not progress at 129 days, with complete or partial resolution occurring in 5 of 14 previously stenosed veins.

Does segmental pulmonary vein ostial ablation lead to progression of pulmonary vein stenosis in patients with recurrent atrial fibrillation?
Progression of pulmonary vein stenosis after initial atrial fibrillation ablation is uncommon in the medium term, with partial or complete resolution occurring in approximately one-third of cases.
Jin et al. (2004) conducted an observational in Atrial fibrillation (n=26). Segmental pulmonary vein potential-guided ostial ablation was evaluated on Progression of pulmonary vein stenosis. Pulmonary vein stenosis after initial electrical isolation did not progress at 129 days, with complete or partial resolution occurring in 5 of 14 previously stenosed veins.
