Pulmonary Vein Stenting for the Treatment of Acquired Severe Pulmonary Vein Stenosis after Pulmonary Vein Isolation: Clinical Implications after Long‐Term Follow‐Up of 4 Years
Why the study?
Does pulmonary vein stenting prevent restenosis in patients with severe acquired pulmonary vein stenosis after atrial fibrillation ablation?
Population
10 patients with 13 severe acquired pulmonary vein stenoses after catheter ablation of atrial fibrillation

Implication
Stenting may support durable patency in severe post-ablation PV stenosis; leaves open need for prospective trials to quantify late restenosis risk.
Structured PICO
Does pulmonary vein stenting prevent restenosis in patients with severe acquired pulmonary vein stenosis after atrial fibrillation ablation?
P
Population
10 patients with 13 severe acquired pulmonary vein stenoses (PVS) after catheter ablation of atrial fibrillation
I
Intervention
Pulmonary vein stenting with Palmaz Genesis stents (stent sizes ≥10 mm)
O
Outcome
Occurrence of restenosis after PV stentingsurrogate
Pulmonary vein stenting provides adequate long-term treatment for severe acquired pulmonary vein stenosis, with stable normalization of lung perfusion, though late in-stent restenosis can still occur.
