Incidence of Atrial Fibrillation Post‐Cavotricuspid Isthmus Ablation in Patients with Typical Atrial Flutter: Left‐Atrial Size as an Independent Predictor of Atrial Fibrillation Recurrence

Abstract

At long-term follow-up, approximately 82% of patients post-cavotricuspid isthmus ablation for atrial flutter developed drug refractory atrial fibrillation. This finding suggests that elimination of atrial flutter might delay, but does not prevent, atrial fibrillation. Evidence suggests both arrhythmias may share common triggers and such patients may derive a better long-term benefit from anatomical ablative treatment of atrial fibrillation as well.
