Key result
Fluoro-less pulsed field ablation achieves safe pulmonary vein isolation without pacemaker interference.
Why the study?
There is a paucity of data on the use of a variable loop circular catheter for pulsed field ablation in patients with cardiac implantable electronic devices.
Does fluoro-less pulsed field ablation with a variable loop circular catheter achieve safe and effective pulmonary vein isolation in a patient with a permanent pacemaker?

Does fluoro-less pulsed field ablation with a variable loop circular catheter achieve safe and effective pulmonary vein isolation in a patient with a permanent pacemaker?
This case report demonstrates the initial feasibility and acute safety of fluoro-less pulsed field ablation using a variable loop circular catheter in patients with permanent pacemakers.
Supports fluoro-less PFA feasibility in pacemaker patients; hypothesis-generating, requiring larger studies before practice change.
There is a paucity of data on the use of a variable loop circular catheter (VLCC) for pulsed field ablation (PFA) in patients with cardiac implantable electronic devices (CIEDs). To date, this is the first case report to demonstrate fluoro-less pulmonary vein isolation using the VLCC in a patient with a dual chamber, permanent pacemaker.

Chan et al. (2025) conducted a case report in Paroxysmal atrial fibrillation (n=1). Variable loop circular catheter (VLCC) for pulsed field ablation (PFA) was evaluated on Fluoro-less pulmonary vein isolation and pacemaker function. Fluoro-less pulmonary vein isolation using a variable loop circular catheter for pulsed field ablation was safely performed in a patient with a permanent pacemaker, with no device malfunction or complications.
