Abstract:
Pulsed-field ablation (PFA) in patients with an implanted extravascular implantable cardioverter-defibrillator (EV-ICD) poses theoretical risks of electromagnetic interference or lead displacement. We report two cases of atrial fibrillation (AF) ablation using the FARAPULSE pentaspline catheter after EV-ICD implantation. In both patients, PFA was successfully performed without significant changes of the parameters/functions of the EV-ICDs. No lead dislodgement was observed on a fluoroscopy examination. These cases suggest that AF ablation using PFA can be safely performed in patients with EV-ICDs.
