Percutaneous retrieval of an interatrial septal occluder device embolized into the aortic arch.

Percutaneous closure of secundum atrial septal defects (ASD) may be complicated by immediate embolization. We report on a 35-year-old woman who underwent percutaneous device closure for a secundum ASD. The diameter of the defect was measured as 4 mm by two-dimensional transesophageal echocardiography and a 7-mm Figulla ASD occluder device was implanted without prior balloon sizing of the defect. Immediate embolization was noted into the aortic arch. Attempts to pull the devices into the sheath with a loop snare failed even after replacing the delivery sheath with a bigger one. Finally, a bioptome was used to grab and place the screw mechanisms in the sheath and percutaneous retrieval of the embolized ASD occluder was achieved. Balloon sizing was performed after removal, yielding a stretched diameter of 12 mm and a 15-mm device was deployed with success.
