Figure 1 The Amplatzer duct occluder device. In this example of a 10/8 device, the "10" refers to the aortic end of the device, and "8" refers to the pulmonary end. The retention disk on the aortic end is generally 4 to 5 mm larger in diameter than the aortic end's diameter.

Figure 2 (A) Lateral angiogram of a patient with a ductus measuring  4 mm in diameter at its narrowest portion. (B) Lateral angiogram of same patient after implantation of an 8/6 device in the ductus, demonstrating a small residual "smoke"-like shunt. This shunt completely closed on post-catheterization day 1.
