Pulsed-field ablation for the management of para-Hisian accessory pathways in patients

Introduction: We present the application of pulsed-field ablation (PFA) for the treatment of para-Hisian accessory pathways (APs). Medthods: We consecutively enrolled patients diagnosed with paroxysmal supraventricular tachycardia (PSVT) to undergo PFA isolation. Two patients of this series exhibited para-Hisian AP and experienced frequent palpitations. The JJEC PFA catheter were used to deliver PFA applications. Results: No complications occurred, even when pulsed ablation was performed in proximity to the His bundle. During the 6-month follow-up visits, the patients remained free of palpitations and arrhythmias. Conclusions: This report suggests that PFA serve as a novel and effective modality for para-Hisian AP ablation.
