Key result
Zero-fluoroscopy pulsed field ablation proves feasible for paroxysmal AF in small case series.
Why the study?
Zero-fluoroscopic pulsed field ablation (PFA) represents an advancement in pulmonary vein isolation for atrial fibrillation, but its workflow feasibility was not established.

Answers are grounded in this paper and cite their sources.
A zero-fluoroscopic workflow for pulsed field ablation using intracardiac echocardiography and a visualized sheath is feasible for pulmonary vein isolation in paroxysmal atrial fibrillation.
Background: Zero-fluoroscopic pulsed field ablation (PFA) is the next step in advancing pulmonary vein isolation (PVI) for atrial fibrillation (AF). Methods: A workflow incorporating a variable-loop circular PFA catheter, intracardiac echocardiography (ICE), and a visualized sheath was applied to 15 paroxysmal AF patients. Results: It consisted of three steps: (1) positioning a non-magnetic mapping catheter in the coronary sinus after creating a right atrial matrix, (2) transseptal puncture with the sheath advancement to the left atrium under ICE guidance, and (3) PFA confirming catheter-tissue contact with tissue proximity indication. Conclusions: This zero-fluoro PFA workflow is feasible without advanced technique.
