Predictors of first pass isolation of the pulmonary veins in real world ablations: An analysis of 2671 patients from the REAL‐AF registry

During atrial fibrillation ablation (AFA), achievement of first pass isolation (FPI) reflects effective lesion formation and predicts long-term freedom from arrhythmia recurrence. We aim to determine the clinical and procedural predictors of pulmonary vein FPI.
