Typical atrial flutter commonly occurs in patients with atrial fibrillation (AF). Limited information exists regarding the effects of concurrent atrial flutter on the long-term outcomes of rhythm control. The data were obtained from a multicenter registry of cryoballoon ablation for AF ( n  = 2,689).
