Percutaneous atrial septal defect closure is routinely performed nowadays because of the ease of implantation as well as the low complication rate. The Atriasept ASD occluder is a low profile, double disc device; over the years several modifications have been made. We report two cases of aortic sinus perforation by the Atriasept ASD occluder (model 2007). Two asymptomatic patients, in whom the device was implanted, were noticed to have metal projecting into the aorta. Real-time fluoroscopy showed fractures of the outer metal ring with abnormal movement of one of the struts of the device. One patient is being conservatively managed and in the other the device was surgically removed due to the presence of a second ASD, which needed closure. Transesophageal echocardiography and fluoroscopy may be necessary to identify this potentially life-threatening complication of this device.
由于植入操作简便且并发症发生率低，经皮房间隔缺损封堵术如今已常规开展。Atriasept房间隔缺损封堵器是一种低轮廓的双盘装置；多年来已进行了多项改进。我们报告了两例Atriasept房间隔缺损封堵器（2007型）导致主动脉窦穿孔的病例。两名植入该装置的无症状患者被发现有金属突入主动脉。实时荧光透视检查显示外部金属环骨折，装置的一个支柱出现异常移动。一名患者正在接受保守治疗，另一名患者因存在第二个需要封堵的房间隔缺损而接受了手术取出装置。经食管超声心动图和荧光透视检查可能有助于识别该装置这一潜在的危及生命的并发症。
