Abstract
AbstractBackgroundZero‐fluoroscopic pulsed field ablation (PFA) is the next step in advancing pulmonary vein isolation (PVI) for atrial fibrillation (AF).MethodsA workflow incorporating a variable‐loop circular PFA catheter, intracardiac echocardiography (ICE), and a visualized sheath was applied to 15 paroxysmal AF patients.ResultsIt 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.ConclusionsThis zero‐fluoro PFA workflow is feasible without advanced technique.
