Infective endocarditis of a fully endothelialized cardiac prosthesis, and especially the late presentation of endocarditis, challenges our current understanding of device-related complications. Late bacterial endocarditis associated with the Amplatzer Septal Occluder, a device frequently used to close atrial septal defects, has been documented only rarely. We report the case of an intravenous drug user who had late infective endocarditis associated with his Amplatzer Septal Occluder, secondary to methicillin-sensitive Staphylococcus aureus bacteremia nearly 14 years after device insertion. The patient recovered after surgical excision and débridement of the vegetative mass, which may be the first time that a surgical approach has been taken to treat this condition. This report corroborates the need for late screening of high-risk patients who have septal occluder devices.
完全内皮化心脏假体的感染性心内膜炎，尤其是心内膜炎的晚期表现，挑战了我们对器械相关并发症的现有认识。与经常用于封堵房间隔缺损的 Amplatzer 房间隔封堵器相关的晚期细菌性心内膜炎极为罕见。我们报告了一例静脉药物使用者的病例，他在装置置入近 14 年后因耐甲氧西林金黄色葡萄球菌菌血症而发生与 Amplatzer 房间隔封堵器相关的晚期感染性心内膜炎。患者在手术切除和清创赘生物后痊愈，这可能是首次采用手术方法治疗这种情况。该报告证实了对有房间隔封堵器的高危患者进行晚期筛查的必要性。
