Key result
Biatrial ablation was more effective than left atrial ablation in maintaining sinus rhythm, although it was associated with a higher frequency of permanent pacemaker implantation.
Why the study?
Does biatrial surgical ablation improve freedom from atrial fibrillation compared to left atrial ablation in patients with long-standing persistent atrial fibrillation undergoing concomitant open heart surgery?
Systematic Review
Does biatrial surgical ablation improve freedom from atrial fibrillation compared to left atrial ablation in patients with long-standing persistent atrial fibrillation undergoing concomitant open heart surgery?
Biatrial surgical ablation during concomitant open heart surgery provides better long-term rhythm control for persistent atrial fibrillation than left atrial ablation, but at the cost of an increased risk for permanent pacemaker implantation.

Biatrial ablation may improve sinus rhythm maintenance over left atrial ablation during cardiac surgery; leaves open optimal lesion set and pacemaker trade-offs pending randomized trials.

Kalybekova et al. (2019) conducted a systematic review in Long-standing persistent atrial fibrillation with concomitant heart disease. Biatrial ablation vs. Left atrial ablation was evaluated on Freedom from atrial fibrillation. Biatrial ablation was more effective than left atrial ablation in maintaining sinus rhythm, although it was associated with a higher frequency of permanent pacemaker implantation.
