Percutaneous mechanical closure of the left atrial appendage (LAA) is a valuable stroke prevention strategy in patients with atrial fibrillation and contraindication to oral anticoagulation. LAA thrombus is a common finding in patients with atrial fibrillation and frequently fails to resolve despite therapeutic anticoagulation. In this scenario, LAA occlusion device implant is generally discouraged due to the high risk of thrombus dislodgement and embolization; however, alternative management options are limited. We report the first case of a successful LAA occlusion device (Watchman-FLX) implant in the presence of a proximal thrombus.
经皮机械闭合左心耳（LAA）是房颤合并口服抗凝禁忌患者预防卒中的一项重要策略。房颤患者常存在左心耳血栓，尽管给予了抗凝治疗，但血栓仍难以消除。在此情况下，由于血栓脱落和栓塞风险高，一般不建议植入左心耳封堵装置；但可供选择的治疗方法有限。我们报告首例近端血栓形成的患者成功植入左心耳封堵装置（Watchman-FLX）。
