Abstract
Pulsed-field ablation (PFA) is a newer energy delivery method, an alternative to thermal lesion, allowing for safe and durable pulmonary vein isolation in the context of atrial fibrillation ablation. Graded tissue sensitivity allows for specifically targeting atrial cardiomyocytes, rendering collateral damage to nearby nerves and vessels unlikely. In the present rapid communication, we report on our center's initial experience with a novel PFA platform and describe the ways in which it can be used targeting sites beyond PV ostia and antra, in the context of atrial fibrillation/flutter/tachycardia ablation, alone or in conjunction with a mainstream 3-dimensional electroanatomical mapping system (3D-EAM). More specifically, the exploratory application of PFA in the vicinity of pacemaker/defibrillator leads may prove of particular significance for clinical practice, given the frequent need to isolate the superior vena cava in patients bearing a transvenous cardiac rhythm management device.
