Clinical and Electrophysiological Predictors of Arrhythmic Recurrence in Patients With Paroxysmal AF Undergoing First Ablation Procedure of AF by Pulmonary Vein Isolation

All patients will undergo, as clinically indicated, AF ablation by pulmonary vein isolation achievable by radiofrequency, cryoenergy, or electroporation. All patients will preliminarily undergo electroanatomic mapping of the atrium by CARTO/Navx/Rhythmia system indifferently. Patients will be given follow-up visits at 3-6-12 months, during which any arrhythmic recurrences will be assessed

There's no patient involvement. Data of patients who underwent ablative procedures two years before the start of the study will be retrospectively analyzed
