Risk of Atrial Fibrillation After Atrial Flutter Ablation: Impact of AF History, Gender, and Antiarrhythmic Drug Medication

Abstract

AF occurrence after AFL ablation is frequent (>20%), especially in patients with a history of AF, in female patients, and in patients treated with class I antiarrythmics/amiodarone prior to AFL. Since most patients who experience AF after AFL ablation have a CHA2DS2-VASc ≥1, the decision to stop anticoagulants after ablation should be considered on an individual basis.
