Imaging findings

Metallic device straddling the left and right atria, initially misidentified as an atrial septal occluder. The device was later identified as a migrated birdcage IVC filter residing in the PFO.

Key takeaways

Unexpected intracardiac metallic devices should prompt consideration of migrated vascular hardware, such as IVC filters, especially in patients with prior trauma or interventional history.
