Coronaries. Cropping the 3D dataset from the side initially reveals the lumen of the proximal right coronary artery (R) encased by infiltrated tissue. Further cropping one slice at a time in the same direction demonstrates the origin of the right coronary artery adjacent to the right coronary cusp and the origin of the left main coronary artery (L) adjacent to the left coronary cusp. Further cropping shows the lumen of the left main coronary artery (L) encased by infiltrated tissue, and further cropping shows infiltrated tissue (arrows) encasing the AV. There is no compression of the lumen of any of the coronary arteries visualized. The pacemaker lead (arrowhead) is shown in the RV.
