Catheter interventional treatment of atrial septal defect (ASD) is widely accepted. The ASD occluder system (ASDOS) is no longer a widely used device nowadays. However, it is implanted in a substantial number of patients. We report a case of severe left-to-right shunt 8 years after catheter interventional closure of an ASD with an ASDOS device. The shunt was due to a membrane perforation, while the arms of the device were not dislocated. Microscopy, microbiology, and histology could not establish a proper explanation for the dysfunction; so long-term follow-up investigation may be required in patients with an implanted ASDOS device.
房间隔缺损（ASD）的导管介入治疗已被广泛接受。ASD封堵器系统（ASDOS）如今已不再是广泛使用的器械。然而，仍有相当数量的患者植入了该器械。我们报告了1例患者，在使用ASDOS器械经导管介入封堵ASD 8年后出现严重的左向右分流。分流是由于膜穿孔所致，而器械的臂并未脱位。显微镜检查、微生物学检查和组织学检查均无法对功能障碍做出合理解释；因此，对于植入ASDOS器械的患者可能需要进行长期随访调查。
