Key result
Pulsed-field ablation using a pentaspline catheter was successfully performed in two patients with extravascular ICDs without significant changes in device parameters or lead dislodgement.
Why the study?
Pulsed-field ablation in patients with an implanted extravascular implantable cardioverter-defibrillator poses theoretical risks of electromagnetic interference or lead displacement.
Is pulsed-field ablation safe and feasible without causing electromagnetic interference or lead displacement in patients with an extravascular ICD?

Is pulsed-field ablation safe and feasible without causing electromagnetic interference or lead displacement in patients with an extravascular ICD?
Pulsed-field ablation using a pentaspline catheter appears safe and feasible in patients with extravascular ICDs, without causing electromagnetic interference or lead dislodgement.
Supports feasibility of PFA in EV-ICD patients; leaves open need for larger prospective studies to confirm safety.
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.

Onuki et al. (2026) conducted a case report in Atrial fibrillation (n=2). Pulsed-field ablation (PFA) using the FARAPULSE pentaspline catheter was evaluated on Changes in EV-ICD parameters/functions and lead dislodgement. Pulsed-field ablation using a pentaspline catheter was successfully performed in two patients with extravascular ICDs without significant changes in device parameters or lead dislodgement.
