Key result
PFA cuts atrial tachyarrhythmia recurrence ~17% vs. traditional ablation in persistent AF.
Why the study?
Pulsed field ablation has emerged as an innovative non-thermal approach with significant promise for treating AF, but its comparative performance against traditional ablation in persistent AF warranted systematic evaluation.
Does pulsed field ablation reduce the recurrence of atrial tachyarrhythmias compared to traditional ablation in patients with persistent atrial fibrillation?
Meta-Analysis (n=1,610)
Does pulsed field ablation reduce the recurrence of atrial tachyarrhythmias compared to traditional ablation in patients with persistent atrial fibrillation?
Relative Risk: 0.83 (95% CI 0.7–0.97)
p-value: p=0.02
Pulsed field ablation is an effective and safe alternative to traditional thermal ablation for persistent atrial fibrillation, offering shorter procedure times and lower rates of atrial tachyarrhythmia recurrence.
PFA may be favored for PerAF; extends comparative evidence supporting its safety and efficiency.
Background Pulsed field ablation (PFA) has emerged as an innovative non-thermal approach with significant promise for treating atrial fibrillation (AF). We performed a meta-analysis between PFA and traditional ablation (TA, including cryoballoon ablation [CBA] and radiofrequency ablation [RFA]) for persistent atrial fibrillation (PerAF). Methods A systematic search was conducted in the Medline, PubMed, Embase, and Cochrane Library databases to include all relevant studies that compared PFA with TA. Results Six trials involving 1,610 patients were included in the study. Pooled analyses revealed that PFA exerted significant advantages over TA, characterized by lower recurrence of atrial tachyarrhythmias (ATAs) (risk ratio [RR]: 0.83; 95% CI: 0.70 to 0.97; P = 0.02). Further analysis revealed no significant difference when PFA was compared with CBA alone (RR: 0.89, 95% CI: 0.74 to 1.08, P = 0.24), whereas PFA was superior to RFA (RR: 0.75, 95% CI: 0.59 to 0.96, P = 0.02). For AF recurrence, PFA also demonstrated a lower rate compared with TA (RR: 0.79, 95% CI: 0.65 to 0.95, P = 0.01), and this advantage was also observed in the comparison with CBA (RR: 0.71, 95% CI: 0.52 to 0.99, P = 0.04). No significant difference was found between PFA and TA in terms of the atrial tachycardia/atrial flutter (AT/AFL). In addition, PFA significantly shortened the procedural time (standard mean difference [SMD]: −1.25, 95% CI: −1.87 to −0.64, P < 0.00001) and left atrial dwell (LAD) time (SMD: −0.51, 95% CI: −0.99 to −0.03, P = 0.04). However, PFA required a longer fluoroscopy time compared with RFA (SMD: 1.67, 95% CI: 1.12 to 2.22, P < 0.00001). There was no significant difference in the incidence of complications between the two groups. Conclusion PFA is effective and safe for PerAF treatment, featuring shorter procedure time and lower ATAs recurrence.

Li et al. (2026) conducted a meta-analysis in Persistent atrial fibrillation (PerAF) (n=1,610). Pulsed field ablation (PFA) vs. Traditional ablation (TA, including cryoballoon ablation and radiofrequency ablation) was evaluated on Recurrence of atrial tachyarrhythmias (ATAs) (RR 0.83, 95% CI 0.70 to 0.97, p=0.02). Pulsed field ablation significantly reduced the recurrence of atrial tachyarrhythmias (RR 0.83) compared to traditional ablation in patients with persistent atrial fibrillation.
