摘要

一名 67 岁的男子曾因缺血性心肌病、心房颤动和左心房阑尾闭塞（LAAO）导致心力衰竭（HF），后因严重的功能性二尖瓣反流而导致 HF 恶化。因此，患者接受了经导管边缘到边缘修补术（TEER）。尽管TEER取得了成功，但术后第3天意外发现左心房（LA）内有一个大血栓。血栓的形成可能与 LA 血流的变化、房间隔穿刺造成的内皮损伤以及抗血栓治疗不足有关。本病例强调了 TEER 术后亚急性 LA 血栓形成的可能性，即使是既往有 LAAO 的患者也不例外。

Left Atrial Thrombus after Transcatheter Mitral Edge-to-Edge Repair in a Patient with Left Appendage Occlusion.

A 67-year-old man with a history of heart failure (HF) secondary to ischemic cardiomyopathy, atrial fibrillation, and left atrial appendage occlusion (LAAO) developed worsening HF secondary to severe functional mitral regurgitation. Consequently, transcatheter edge-to-edge repair (TEER) was performed. Despite successful TEER, a large thrombus in the left atrium (LA) was unexpectedly discovered on postoperative day 3. Thrombus formation may be related to changes in the blood stream in the LA, endothelial injury by septal puncture, and an insufficient anti-thrombotic regimen. This case highlights the potential for the development of subacute LA thrombosis following TEER, even in patients with prior LAAO.
