CTICasesDislodged Atrial Septal Defect (ASD) Occluder Device
Imaging findings
Sequential chest radiographs taken an hour apart demonstrate a sudden, abnormal change in the position of an atrial septal defect (ASD) occluder device. Echocardiography confirms the device has completely dislodged from the interatrial septum and is free-floating within the right atrium.
Key takeaways
Embolization or dislodgement of an ASD occluder device is a rare but serious post-procedural complication that typically occurs within 24 hours of implantation. Radiologists must carefully check the position of cardiac devices on post-operative serial radiographs, as migration can lead to life-threatening arrhythmias, valvular damage, or systemic embolization, requiring immediate open-heart surgical retrieval and repair.
