A 62-year-old woman presents for pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation. During transseptal catheterization (TSC) the patient sustained mechanical injury to the atrioventricular node (AVN) with consequent complete heart block (CHB). Injury to the AVN and CHB recovered after approximately forty minutes. The patient subsequently underwent a successful PVI with the remainder of the hospital stay uneventful. We present a case of reversible injury to the AVN caused by a steerable introducer sheath during TSC and discuss the mechanisms of injury as well as potential measures to avoid such a complication in the future.
一名62岁女性因阵发性心房颤动接受肺静脉隔离术(PVI)。在经房间隔导管消融术(TSC)过程中,患者的房室结(AVN)受到机械损伤,继而出现完全性心脏传导阻滞(CHB)。约40分钟后,房室结损伤及完全性心脏传导阻滞恢复。患者随后成功接受了肺静脉隔离术,住院期间其余情况平稳。我们报告一例在经房间隔导管消融术期间可操纵的导入鞘导致房室结可逆性损伤的病例,并讨论损伤机制以及未来避免此类并发症的潜在措施。
