Key result
PFA matches cryoballoon ablation for tachyarrhythmia recurrence but cuts procedure time and phrenic nerve palsy.
Why the study?
Pulsed-field ablation is an emerging AF ablation technology, but few studies have compared the clinical advantages and disadvantages of PFA versus cryoballoon ablation.
Does pulsed-field ablation with a pentaspline catheter reduce atrial tachyarrhythmia recurrence and complications compared to cryoballoon ablation in patients with atrial fibrillation?
Meta-Analysis (n=2,024)
Does pulsed-field ablation with a pentaspline catheter reduce atrial tachyarrhythmia recurrence and complications compared to cryoballoon ablation in patients with atrial fibrillation?
Odds Ratio: 0.71 (95% CI 0.48–1.06)
p-value: p=0.09
Pulsed-field ablation using a pentaspline catheter demonstrates comparable overall efficacy to cryoballoon ablation for atrial fibrillation, with shorter ablation times and a significantly lower risk of phrenic nerve palsy.
Pulsed-field ablation offers similar efficacy with shorter procedures and less phrenic nerve palsy; extends randomized evidence for its use versus cryoballoon ablation.
Background Pulsed‐field ablation (PFA) is an emerging technology for atrial fibrillation (AF) ablation. However, there is few studies comparing the clinical advantages and disadvantages of PFA and cryoballoon ablation (CBA). This study aimed to perform a comprehensive meta‐analysis to evaluate the efficacy and safety of PFA using a pentaspline ablation catheter compared with CBA for treating AF. Methods This study was registered in the International Prospective Register of Systematic Reviews (ID: CRD420251061599). Studies comparing PFA using a pentaspline ablation catheter with CBA for pulmonary vein isolation (PVI) were systematically searched from database inception to March 2025. Results Six trials involving 2024 patients were included. No significant difference was observed in atrial tachyarrhythmia recurrence between PFA and CBA (OR) = 0.71; 95% confidence interval (CI): 0.48 to 1.06). However, in patients with paroxysmal AF, the PFA group exhibited a lower incidence of AT recurrence (OR = 0.62; 95% CI: 0.46 to 0.85). PFA was superior to CBA in terms of ablation time (MD) = −14.12; 95% CI: −16.31 to −11.93) and left atrial dwell time (MD = −9.44; 95% CI: −15.69 to −3.19). Hypersensitive troponin release was higher in the PFA group (MD = 547.29; 95% CI: 53.55 to 1041.03), while CBA was associated with a higher incidence of phrenic nerve palsy (OR = 0.06; 95% CI: 0.01 to 0.30). Conclusion PFA demonstrates superior safety and efficacy compared with CBA for PVI in patients with AF. These findings provide additional procedural options for patients and electrophysiologists in clinical practice.

Cai et al. (2026) conducted a meta-analysis in Atrial Fibrillation (n=2,024). Pulsed-field ablation (PFA) vs. Cryoballoon ablation (CBA) was evaluated on Atrial tachyarrhythmia recurrence (OR 0.71, 95% CI 0.48 to 1.06, p=0.09). Pulsed-field ablation resulted in no significant difference in overall atrial tachyarrhythmia recurrence compared to cryoballoon ablation (OR 0.71), but significantly reduced ablation time and the incidence of phrenic nerve palsy.
