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).

Biatrial atrial tachycardia (BiAT) is a rare form of atypical macro-reentrant AT (MRAT) that can be difficult to characterize and ablate. Ablation of regions demonstrating spatiotemporal dispersion (SD) has shown a high rate of atrial fibrillation (AF) termination to either sinus or MRAT during ablation.
