Why the study?
Do surgical ablation procedures (complete Cox-maze or hybrid maze) improve maintenance of normal sinus rhythm compared to catheter ablation in patients with atrial fibrillation?

Key result
Surgical treatments, including the hybrid maze (57.9%) and complete Cox-maze (72.7%), were significantly superior to catheter ablation (20.3%) in maintaining normal sinus rhythm at 2 years (p<0.001).

Do surgical ablation procedures (complete Cox-maze or hybrid maze) improve maintenance of normal sinus rhythm compared to catheter ablation in patients with atrial fibrillation?
Absolute Event Rate: 57.9% vs 20.3%
p-value: p=<0.001
Surgical ablation procedures (Cox-maze and hybrid maze) are more effective than catheter ablation at maintaining normal sinus rhythm at 2 years in patients with atrial fibrillation, but are associated with significantly higher major complication rates.
Genev et al. (2017) conducted a cohort in Atrial fibrillation (n=140). Hybrid maze and complete Cox-maze vs. Radiofrequency catheter ablation was evaluated on Normal sinus rhythm at 2 years (p=<0.001). Surgical treatments, including the hybrid maze (57.9%) and complete Cox-maze (72.7%), were significantly superior to catheter ablation (20.3%) in maintaining normal sinus rhythm at 2 years (p<0.001).
