Abstract

A 67-year-old female with symptomatic paroxysmal atrial fibrillation (AF) underwent left atrial circumferential ablation, and during the procedure, she developed AF. Once the ablation was complete, the left upper pulmonary vein (LUPV) appeared to continue in a rapid disorganized rhythm, despite further attempts at isolating this vein. When the patient was electrically cardioverted to sinus rhythm to assist mapping, the LUPV remained in a disorganized rhythm, pulmonary vein (PV) fibrillation. This case illustrates a possible pitfall in confirming complete isolation of the PVs during AF.

摘要

一名67岁有症状的阵发性心房颤动（AF）女性接受了左心房环周消融术，术中她发生了房颤。消融完成后，尽管进一步尝试隔离左上肺静脉（LUPV），该静脉仍以快速紊乱的节律持续跳动。当患者经电复律转为窦性心律以辅助标测时，LUPV仍保持紊乱节律，即肺静脉（PV）颤动。该病例说明了在房颤期间确认肺静脉完全隔离时可能存在的一个陷阱。
