摘要

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.
