Abstract

Background: TEER has revolutionized mitral regurgitation treatment, addressing clinical burden in aging patients. However, thrombotic complications may still occur.

Case presentation: An 83-year-old man with severe mitral regurgitation underwent a MitraClip procedure. A large molding thrombus was observed during the procedure, despite a targeted ACT. To prevent cerebral embolization, two carotid filters were placed. The procedure was successfully completed, and mitral regurgitation was reduced. The patient was stable during the procedure, with no evidence of pulmonary or cerebral embolism.

Conclusions: The case highlights the importance of close observation and multidisciplinary decision-making in managing acute thrombus during TEER. Further research is needed to establish the potential role of cerebral protection devices and the effect of anticoagulation procedures on thrombus formation.

每一个伟大的故事似乎都是从一条蛇开始的：在MitraClip手术中遇到的大右心房血栓的病例报告。

背景：TEER彻底改变了二尖瓣反流治疗，解决了老年患者的临床负担。然而，血栓性并发症仍可能发生。病例介绍：一位患有严重二尖瓣返流的83岁男性接受了二尖瓣夹手术。尽管有靶向ACT，但在手术过程中观察到一个大的成型血栓。为了防止脑栓塞，放置了两个颈动脉过滤器。手术成功完成，二尖瓣返流减少。手术过程中患者病情稳定，无肺栓塞或脑栓塞迹象。结论：该病例强调了密切观察和多学科决策在TEER期间处理急性血栓的重要性。需要进一步的研究来确定脑保护装置的潜在作用以及抗凝手术对血栓形成的影响。
