Atrial septal defect (ASD) closure device
Atrial septal defects (ASDs) are among the most common congenital heart defects. Left-to-right shunting can lead to right heart enlargement and dysfunction, with some patients developing pulmonary hypertension.
Closure of an atrial septal defect (ASD) is done surgically or, in select patients with a secundum ASD, via a percutaneous device. Contemporary ASD closure devices include the Amplatzer Septal Occluder, Gore CARDIOFORM Septal Occluder, Occlutech ASD Occluder, the Ceraflex ASD Occluder, and the Nit-Occlud ASD-R. Devices previously in use include the CardioSEAL Septal Occlusion System, the STARFlex device, and the Gore HELEX.
Many of these devices use a nickel-titanium alloy called nitinol, which is mildly radiopaque as seen in our patient. This device can be difficult to appreciate in the frontal view, as it overlays the spinal column. It is more easily viewed in the lateral film.
