Risk of new-onset atrial fibrillation and stroke after radiofrequency ablation of isolated, typical atrial flutter.

Background: Radiofrequency ablation (RFA) is considered a curative procedure for typical atrial flutter (AFL); however, patients remain at risk for developing new atrial fibrillation (AF).

Objective: The purpose of this study was to determine the incidence and predictors of new-onset AF and stroke after RFA of isolated AFL in a multicenter cohort.

Methods: The study included 315 consecutive patients who underwent successful RFA of isolated, typical AFL from 2006 to 2013 at 4 community and teaching hospitals.
