Pulsed field ablation shows favorable results for freedom from AF compared to other catheter ablation technologies in patients with atrial fibrillation.
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.
