- Pulmonary veins (PVs) are major sources of atrial fibrillation (AF) triggers, but non-PV (NPV) triggers also exist.
- The study assessed outcomes of first-time AF ablation based on NPV trigger status, including recurrence rates.
- Patients without NPV triggers had a 29.5% one-year recurrence rate, while those with ablated NPV triggers had 38.2%, and untreated NPV triggers had 72.2%.
- Ablation of NPV triggers reduces recurrence rates but their presence still indicates a modestly worse prognosis.
- The study highlights the importance of identifying and targeting NPV triggers to improve AF ablation outcomes.
