Abstract

We present a case of a 75-year-old man who developed an acute left atrial appendage thrombus immediately following mitral valve transcatheter edge to edge repair despite adequate intraprocedural anticoagulation. The patient was managed with enoxaparin to warfarin bridging with no obvious thromboembolic events on follow-up. Attention to anticoagulation is important to reduce thromboembolic risk during mitral valve transcatheter edge to edge repair. ( Level of Difficulty: Intermediate. )
