Indirect treatment comparison of two pulsed field ablation systems for the treatment of persistent atrial fibrillation.

Background: Catheter ablation is beneficial in patients with symptomatic persistent atrial fibrillation (PerAF), and pulsed field ablation (PFA) is a promising energy source to safely and durably create ablation lesions. However, catheter-specific "PFA waveforms and designs" result in effectiveness and safety profiles that are not transferable to other PFA technologies. A head-to-head comparison between the dual-energy, wide-footprint lattice-tip (Sphere-9, Medtronic) and pentaspline PFA catheter (Farawave, Boston Scientific) is not yet available.

Introduction: Fluoroless mapping and ablation using a Pentaspline pulsed field ablation catheter has many advantages. This can be achieved using a "tripolar configuration," which enables high-quality electroanatomical maps, improves the ability to localize electrograms (EGMs), and minimizes the use of additional mapping catheters compared to the standard bipolar configuration. We aimed to evaluate the benefits of using a tripolar configuration in fluoroless atrial fibrillation ablation compared to the standard bipolar configuration.

Background And Aims: Aim of this study was to assess the risk of hemolysis, the extent of myocardial and neural injury after monopolar, monophasic pulsed field ablation (PFA) using a lattice-tip catheter in comparison to single-shot PF ablation platforms employing bipolar, biphasic waveforms.
Methods: This prospective study included consecutive patients undergoing PFA for atrial fibrillation (AF) using the Affera™ mapping and ablation system (n=40). Biomarkers for hemolysis (haptoglobin, LDH, bilirubin), myocardial injury (high-sensitive troponin T, CK, CK-MB), neurocardiac injury (S100), and renal function (creatinine) were assessed pre- and within 24 hours post-ablation.
