Key result
Pulmonary vein stenting reduces severe post-ablation stenosis to 10% and eliminates home oxygen dependence.
Why the study?
Although pulmonary vein stenosis is a well-documented complication of RFCA for AF, simultaneous involvement of multiple pulmonary veins is extremely rare.
Population
One 69 years-old male patient with persistent AF treated with RFCA 2 years prior

Percutaneous stenting can effectively treat severe, multi-vessel pulmonary vein stenosis, a rare but serious complication of radiofrequency catheter ablation for atrial fibrillation.
Cotella et al. (2022) conducted a case report in Pulmonary veins stenosis after radiofrequency catheter ablation for atrial fibrillation (n=1). Percutaneous stenting of pulmonary veins was evaluated on Reduction in pulmonary vein stenosis. Stenting of the left and right upper pulmonary veins in a patient with extensive post-ablation stenosis reduced the stenosis from 90% to 10% and allowed withdrawal of home oxygen.
