Incidence of Atrial Fibrillation After Atrial Flutter Ablation.

Objectives: This study was conceived to perform a comprehensive systematic review and meta-analysis of the available evidence to compute the incidence of atrial fibrillation (AF) after successful atrial flutter (AFL) catheter ablation, defined by targeting for bidirectional block, using different types of follow-up modalities and durations.

Background: Cavotricuspid-isthmus dependent AFL is usually initiated by short bursts of AF. The incidence of AF after AFL ablation is variable.
