Bipolar RF Cox-Maze may improve AF control over PVI in surgical cohorts; hypothesis-generating and requires randomized confirmation.
Cohort (n=130)
Does bipolar radiofrequency ablation replacing Cox-Maze incisions effectively control atrial fibrillation compared to pulmonary vein isolation alone?
Absolute Event Rate: 90% vs 59%
The use of bipolar radiofrequency ablation to replace Cox-Maze incisions is safe and highly effective at controlling AF, whereas pulmonary vein isolation alone is significantly less effective.
Melby et al. (2006) conducted a cohort in Atrial fibrillation (n=130). Cox-Maze procedure utilizing bipolar radiofrequency ablation vs. Pulmonary vein isolation alone was evaluated on Freedom from atrial fibrillation at last follow-up. The Cox-Maze procedure using bipolar radiofrequency ablation achieved 90% freedom from atrial fibrillation at follow-up, compared to 59% with pulmonary vein isolation alone.
