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.
