Background:
Atrial fibrillation, which has increased in prevalence by 33% over the past two decades, affects 59 million people worldwide. It is treated using thermal and nonthermal techniques like radiofrequency, cryoballoon, laser, and pulsed-field ablation (PFA). This meta-analysis is the first to compare PFA with high-power short-duration radiofrequency ablation (HPSD-RFA).
Methods:
We comprehensively searched PubMed, Cochrane Central, and ScienceDirect from inception to August 2024. In Review Manager 5.4.1, we pooled risk ratios (RRs) and weighted mean difference (WMD) along with 95% confidence intervals for dichotomous and continuous outcomes, respectively, and employed a random effects model. Study quality was assessed via the Newcastle-Ottawa Scale, and funnel plots were used to evaluate the risk of publication bias.
Results:
Seven studies with a total of 1538 patients were analyzed in this meta-analysis. PFA was associated with a shorter total procedural time (MD = -36.39 min; 95% CI: [-46.23, -26.55]; p < 0.00001; I2 = 90%), left atrial dwell time (MD = -33.22 min; 95% CI: [-53.21, -13.23]; p = 0.001; I2 = 93%), and a longer fluoroscopy time compared to the HPSD-RFA (MD = 9.06 min; 95% CI: [6.13, 11.99]; p < 0.00001; I2 = 96%). Other outcomes were comparable between the two arms.
Conclusion:
PFA outperforms HPSD ablation in terms of procedural efficiency outcomes except for the total fluoroscopy time. Still, both techniques are comparable regarding safety and arrhythmia control outcomes.
