What are the predictive factors for early recurrence and delayed cure after radiofrequency catheter ablation in patients with chronic atrial fibrillation?
Effect estimate: OR 1.47 (95% CI 1.05-1.87)
p-value: p=0.02
Achieving AF termination during radiofrequency catheter ablation is an independent predictor of both early recurrence and delayed cure in patients with chronic AF.
Xu et al. (2008) conducted a cohort in Chronic Atrial Fibrillation (n=92). Radiofrequency catheter ablation (RFCA) was evaluated on Delayed cure (OR 1.47, 95% CI 1.05-1.87, p=0.02). Achieving atrial fibrillation termination during radiofrequency catheter ablation independently predicted delayed cure (OR 1.47) in patients with chronic atrial fibrillation.
