Early ablation of newly diagnosed paroxysmal atrial fibrillation (NEWPaAF) versus newly diagnosed persistent atrial fibrillation (NEWPeAF): Comparison of patient populations and ablation outcomes.

Introduction: Little is known about very early atrial fibrillation (AF) ablation after first AF detection.

Methods: We evaluated patients with AF ablation <4 months from newly diagnosed paroxysmal AF (NEWPaAF) and newly diagnosed persistent AF (NEWPeAF). We compared the two patient populations and compared ablation outcomes to those undergoing later ablation.

Very long term outcomes of atrial fibrillation ablation.

Background: Little is known about the very long term durability of atrial fibrillation (AF) ablation.

Objective: The purpose of this study was to evaluate very long term AF ablation outcomes.

Methods: We followed 5200 patients undergoing 7145 ablation procedures.
