摘　　要：本文介绍了花瓣状脉冲电场消融(pulsed field ablation,PFA)导管手术流程,包括穿刺房间隔、PFA导管置入、“231”消融策略,以及肺静脉隔离验证。文章还探讨了提高肺静脉隔离成功率的操作技巧,如导管旋转角度调整、相邻肺静脉间补充消融、肺静脉共干的处理,以及右下肺静脉及上腔静脉的消融操作等。借助规范化的操作流程和技巧,花瓣状PFA导管能够显著提高消融成功率并减少并发症,为心房颤动的治疗提供了一种新的有效手段。This article delineates the procedures of petal-shaped pulsed field ablation(PFA)catheter,which include the puncture of the interatrial septum,insertion of the PFA catheter,implementation of the“231”ablation strategy,and verification of pulmonary vein isolation.Additionally,it explores operational techniques to increase the success rate of pulmonary vein isolation,such as the adjustment of the catheters rotation angle,supplementary ablation between adjacent pulmonary veins,management of common pulmonary vein trunks,and ablation manipulation of the right inferior pulmonary vein and the superior vena cava.By standardized procedural steps and techniques,petal-shaped PFA catheter significantly improves the success rate of ablation and reduces complications,offering a novel and effective approach to the treatment of atrial fibrillation.
