Key result
Surgical patch angioplasty for pulmonary vein stenosis yields initial improvement followed by 9-month restenosis.
Why the study?
Pulmonary vein stenosis develops in 1-3% of patients after radiofrequency ablation for atrial fibrillation and remains a rare and challenging complication with limited available case reports.
Case Report (n=1)
Surgical patch angioplasty for severe pulmonary vein stenosis post-ablation may provide temporary symptomatic relief but is limited by the risk of restenosis.
Initial symptom relief after surgical patch angioplasty for pulmonary vein stenosis does not preclude restenosis; this case leaves open long-term durability.
After radiofrequency ablation for atrial fibrillation, 1-3% of patients develop pulmonary vein stenosis, a rare and challenging complication with limited case reports available. We describe the case of a 51-year-old male with bilateral severe pulmonary vein stenosis following radiofrequency ablation in 2017 and 2022. After interdisciplinary discussion, surgical patch angioplasty via clamshell incision was performed on cardiopulmonary bypass. Although the patient initially showed improved exercise tolerance, he experienced clinical deterioration nine months post-surgery and developed postoperative pulmonary vein restenosis.

Chorąży et al. (2025) conducted a case report in pulmonary vein stenosis after radiofrequency ablation for atrial fibrillation (n=1). Surgical patch angioplasty was evaluated on clinical deterioration and postoperative pulmonary vein restenosis. Surgical patch angioplasty for severe pulmonary vein stenosis initially improved exercise tolerance, but the patient developed clinical deterioration and restenosis 9 months post-surgery.
