Percutaneous left atrial appendage (LAA) closure may reduce the risk of cardioembolic stroke in patients with non-valvular atrial fibrillation. Given the prophylactic nature of the procedure, identifying and managing complications are paramount.
A 73-year-old man presented 14 months after percutaneous LAA closure with syncope and acute pericardial tamponade which required surgical exploration and haemostasis; the most temporally remote account of this complication albeit amongst very few case reports. Tissue erosion by the Amplatzer™ Amulet™ LAA closure device (Abbott, Plymouth, MN, USA) was noted at two separate anatomical locations, corresponding to the device disc and lobe, which has not been described previously.
This case report highlights the anatomical relationship between the LAA and its surrounding structures, and the importance of recognizing the risk of late device erosion.
经皮左心耳（LAA）封堵术可能降低非瓣膜性心房颤动患者发生心源性栓塞性卒中的风险。鉴于该手术的预防性，识别和处理并发症至关重要。
一名73岁男性在经皮LAA封堵术后14个月出现晕厥和急性心包填塞，需要进行手术探查和止血；这是该并发症在极少量病例报告中最遥远的发生时间记录。在两个不同的解剖位置发现了美国雅培公司生产的Amplatzer™ Amulet™ LAA封堵器对组织的侵蚀，分别对应封堵器的盘片和叶部，此前未见相关描述。
本病例报告强调了LAA与其周围结构的解剖关系，以及认识到晚期器械侵蚀风险的重要性。
