Figure 26. Aortic arch cine images in lateral projections illustrating the sequence of Amplatzer duct occluder (ADO) implantation. (A) shows aortic disc of ADO in the ductal ampulla without impinging on the aortic lumen. The remaining unopened ADO is shown with arrow. (B) shows completely expanded ADO in an acceptable position (thick arrow). Tiny residual shunt (thin arow) through the ADO is seen, but no shunt is detected parallel to the device. MC: Marker pigtail catheter; DAo: descending aorta. Modified from Ref.[67].
