Key result
Biatrial cryo-maze yielded a higher rate of freedom from AF without antiarrhythmic drugs at 12 months (82%) compared to epicardial (69%) and endocardial (74%) left atrial procedures.

Does the application technique of concomitant surgical cryoablation affect rhythm outcomes in cardiac surgical patients with atrial fibrillation?
Absolute Event Rate: 82% vs 69%
A complete biatrial lesion set (cryo-maze) yields a higher success rate for maintaining sinus rhythm without antiarrhythmic drugs at 12 months compared to left atrial procedures alone during concomitant cardiac surgery.
Albåge et al. (2011) conducted a cohort in Atrial fibrillation in cardiac surgical patients (n=115). Biatrial cryo-maze vs. Epicardial or endocardial left atrial cryoablation was evaluated on Sinus or pacing rhythm, free of AF without antiarrhythmic drugs at 12 months. Biatrial cryo-maze yielded a higher rate of freedom from AF without antiarrhythmic drugs at 12 months (82%) compared to epicardial (69%) and endocardial (74%) left atrial procedures.
