Atrial septal occluder device embolization to an iliac artery: a case highlighting the utility of three-dimensional transesophageal echocardiography during percutaneous closure.

Percutaneous closure of secundum atrial defects has become an accepted treatment in part because it is minimally invasive and relatively low risk. Despite recent advances in implantation technique and device improvements, complications occur. Here, we report a case of device embolization during percutaneous repair of an atrial septal defect (ASD) with multiple fenestrations. We highlight the value of using live/real time three-dimensional transesophageal echocardiography to help plan the percutaneous procedure and detect complications.
