Key Takeaway
Consider PFA for AF ablation; efficacy favored, but safety data and follow-up not reported.

This network meta-analysis included 10 randomized controlled trials and 4 propensity score-matched studies involving patients with atrial fibrillation. The study compared pulsed field ablation (PFA) against cryoballoon ablation, conventional radiofrequency ablation, and remote magnetic navigation ablation. Primary and secondary outcomes included freedom from atrial fibrillation and other atrial tachyarrhythmias, procedure duration, complication rates, and fluoroscopy time.

PFA was associated with a higher rate of freedom from AF and other atrial tachyarrhythmias compared to the other technologies, with a relative risk of 1.11 (95% CI: 1.03–1.21). Regarding procedure duration, PFA showed a standardized mean difference of -1.43 (95% CI: -2.47 to -0.39), indicating potentially shorter procedures. Absolute numbers for these outcomes were not reported in the source data.

Safety data, including adverse events, serious adverse events, discontinuations, and tolerability, were not reported in the analysis. The study did not provide specific details on complication rates or fluoroscopy time comparisons beyond the main results. Key limitations include the lack of reported follow-up duration and the absence of detailed safety profiles for the interventions.

The choice of ablation technique should be weighed against specific clinical needs and the patient's individual situation. While PFA appears promising for efficacy and efficiency, clinicians must consider the current evidence base and available safety data when making treatment decisions.

AimsThere are several interventional approaches to atrial fibrillation (AF) ablation; however, it is not yet known which procedure is most effective. Our aim was to compare the efficacy and safety of different interventional approaches for the treatment of AF through network meta-analysis.MethodsWe searched randomized controlled trial (RCT) and propensity-score matched (PSM) studies in PubMed, Embase, and Cochrane Library databases from the initial period to December 2024, and studies were selected which had cryoballoon ablation (CBA), conventional radiofrequency ablation (RFA), remote magnetic navigation ablation (RMN), and pulsed field ablation (PFA) as an arm in the study. Network meta-analysis (NMA) was performed using a frequentist approach with STATA (version 14.0) software.ResultsWe included 10 RCT studies and 4 PSM studies. For freedom from AF and other atrial tachyarrhythmias (AT) indicators, PFA may become the most effective ablation procedure (SUCRA = 88.4%, RR = 1.11, 95% CI: 1.03–1.21). For procedure duration, PFA may also be the ablation procedure with the best results (SUCRA = 91.2%, SMD = −1.43, 95% CI: −2.47 to −0.39).ConclusionThe choice of ablation technique needs to be weighed against the specific clinical needs and the patient's situation. PFA may be the best choice if success rate and procedure time are prioritized, while RMN is more appropriate if complication rates and fluoroscopy time are more important.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42025631158, identifier: CRD42025631158.
