A through C, Images of a patient with a small RV-PA conduit that were stored as a collection of bookmarks for roadmapping; D through F, the same images during the catheterization process. B, Pathway from the inferior vena cava to the entrance to the conduit is shown (dashed arrow) on an image that was created with an AP cut-plane. E, Corresponding catheter course is shown. C, Roadmap image that was created with an oblique cut-plane exposing the PA confluence and a hypoplastic left pulmonary artery (LPA). F, Corresponding catheter course with the tip of the catheter positioned in the distal LPA.
