Key clinical message: Atrial fibrillation is closely associated with thrombotic events. In non-valvular atrial fibrillation, 90% of thrombi are formed by the left atrial appendage. Left atrial appendage occlusion (LAAC) can effectively prevent the detachment of left atrial appendage thrombus during atrial fibrillation, thereby reducing the risk of long-term disability or death caused by thromboembolic events. However, the identification and management of complications in LAAC are also very important.
Abstract: The efficacy and safety of left atrial appendage occlusion (LAAC) in preventing non-valvular atrial fibrillation stroke have been confirmed by multiple randomized controlled and registered studies, and have been recommended by several guidelines for stroke prevention in patients with atrial fibrillation at high-risk of stroke. We reported an 80-year-old male patient with persistent atrial fibrillation. The patient underwent left atrial appendage closure surgery due to high risk of embolism and bleeding. On the second day after surgery, echocardiography showed displacement of the left atrial appendage occluder. Immediately perform removal of left atrial appendage occlude and left atrial appendage occlusion on the same day, and the patient was discharged on the fifth day after surgery without any special circumstances. This case demonstrates the feasibility and important clinical significance of using interventional surgery to remove the left atrial appendage occluder after displacement in clinical practice.
