Abstract

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.

零氟脉冲场烧蚀的工作流程。

背景：零透视脉冲场消融（PFA）是推进肺静脉隔离（PVI）治疗心房颤动（AF）的下一步。方法：对15例阵发性房颤患者采用可变回路环形PFA导管、心内超声心动图（ICE）和可视化护套的工作流程。结果：它包括三个步骤：(1)在形成右心房基质后在冠状窦内放置无磁测图导管，(2)在ICE引导下经间隔穿刺鞘推进至左心房，(3)PFA确认导管与组织接触，组织接近指征。结论：无氟PFA工作流程是可行的，无需先进的技术。
