17 years old male patient admitted to the Cardiology department with orthopnea. He had a secundum type atrial septal defect which had been closed with an Amplatzer device 40 days ago. At the one month follow up examination, he was all right with no symptoms or signs of dislocation of the device. Upon his admission, transthoracic echocardiography revealed the dislocation of the device so that it had migrated to the pulmonary artery bifurcation, occluding the left pulmonary artery. We have removed the device and closed the atrial septal defect successfully, performing an open heart procedure.
@hoffm426 Actually, I think the device was a little bit smaller than the defect. The defect was measured as 3 cm in diameter, but I think it was larger than this. The device was 4 cm in diameter at the edges of the umbrellas. So, 1-2 mm of excess of the rim did not suffice for the device to remain in place.

What caused the pulmonary embolization? Just poor deployment of the device? Pulling too hard during implant and deforming the device? Tricky anatomy? Device failure?
