Outcomes and Management of Patients With Severe Pulmonary Vein Stenosis From Prior Atrial Fibrillation Ablation
Key result
Severe PV stenosis complicates ~0.5% of AF ablations, with most treated patients remaining arrhythmia-free.

What are the clinical outcomes and management strategies for patients with severe pulmonary vein stenosis following atrial fibrillation ablation?
P
Population
10,368 patients undergoing atrial fibrillation ablation (2000-2015), with 52 patients (0.5%) diagnosed with severe pulmonary vein stenosis.
I
Intervention
Percutaneous interventions and repeat ablation for severe pulmonary vein stenosis.
O
Outcome
Clinical outcomes and complications in patients with severe pulmonary vein stenosis.safety
Severe pulmonary vein stenosis after AF ablation is rare (0.5%) but associated with significant morbidity, though most patients can remain arrhythmia-free with appropriate management.
Cite This Study
Raeisi‐Giglou et al. (2018) conducted a cohort in Severe Pulmonary Vein Stenosis (n=10,368). Percutaneous interventions and repeat ablation was evaluated on Incidence of severe PV stenosis. Severe pulmonary vein stenosis after atrial fibrillation ablation occurred in 0.5% of patients, with 79% of those treated remaining arrhythmia-free over a median 25-month follow-up.
