It exploits the localized application of short вЂ“ nano/microseconds - high-voltage electric fields to induce irreversible electroporation, a prolonged state or pore-induced permeability that triggers non-necrotic deaths ( Davalos et al., 2005), in the proximal tissue ( Wittkampf et al., 2018 Wojtaszczyk et al., 2018 Sugrue et al., 2019) with high selectivity ( MiklavДЌiДЌ, 2018) and without strict need of contact ( Ramirez et al., 2020). Pulsed field ablation (PFA) is a recent method for interventional treatment of cardiac arrhythmia. Further optimization, with energy titration or longer follow-up, is required for a robust atrial and ventricular AC-PFA. A surviving cardiomyocyte core was visible in basal ventricular lesions.Д¬onclusion: We proved that our method and technology of AC-PFA is feasible and safe for atrial and ventricular myocardial ablation, supporting their systematic investigation into effectiveness evaluation for the treatment of cardiac arrhythmia. We found isolated, transmural and continuous scars. T1-weighted scans revealed specific tissue changes in atria and ventricles, confirmed to be fibrotic scars via trichrome staining. The postmortem chest inspection showed no peripheral damage, but epicardial and endocardial discolorations at sites of ablation. The implemented numerical simulations confirmed the non-thermal nature of our AC-PFA and provided specific information on the estimated treated area and need of pulse trains.

No adverse event (e.g., esophageal temperature rises or gas bubble streams) was observed вЂ“ while twitching was avoided by addition of electrosurgical return electrodes. Acute changes in the atrial and ventricular electrograms were immediately visible at the sites of AC-PFA вЂ“ signals were elongated and reduced in amplitude ( p < 0.0001) and tissue impedance dropped ( p = 0.011). The inter-burst interval was determined by the native heart rhythm вЂ“ 69 В± 9 bpm. Results: We applied square, 50% duty cycle, AC bursts of 100 Ојs duration, 100 kHz internal frequency, 900 V for 60 pulses in the atrium and 1500 V for 120 pulses in the septum. We perform finite element method simulation of our AC-PFA scenarios to corroborate our method and better interpret our findings. After procedure and 4-week follow-up, the animals were euthanized, and the hearts were inspected for tissue changes and characterized. With fluoroscopic and electroanatomical mapping assistance, we performed ECG-gated AC-PFA in the following settings: in the left atrium with a decapolar loop catheter with electrodes connected in bipolar fashion across the interventricular septum applying energy between the distal electrodes of two tip catheters. Methods: We employed 6 female swine вЂ“ weight 53.75 В± 4.77 kg вЂ“ in this study.

We performed a proof-of-concept chronic animal trial to test the feasibility and safety of our method and technology.

We designed an AC-burst generator and therapeutic strategy, based on the existing knowledge between efficacy and safety among different pulses. The therapy offers a potential paradigm shift for catheter ablation of cardiac arrhythmia. Introduction: Pulsed field ablation (PFA) exploits the delivery of short high-voltage shocks to induce cells death via irreversible electroporation.
