Figure 31. Aortic arch and main pulmonary artery (MPA) cine images in lateral projections illustrating the result of placement of an Amplatzer duct occluder II (ADOII) [arrows in (B and C)] across the ductus. (A) shows a moderate patent ductus arteriosus (PDA) [arrow in (A)] with opacification of the MPA. (B) shows that there is no residual shunt. Also, there is no protrusion of the ADOII into the aorta. (C) illustrates appropriate location of the device without blockage of the pulmonary arteries. C1: Catheter in the descending aorta (DAo); C2: catheter in the MPA. Reproduced from Ref.[7].
