  • Fig. 1 Prior to recanalization: Cardiac catheterization showed a prominent RV branch and in-stent occlusion of the mid and distal RCA.
  • Fig. 2 Curved multiplanar reformates showed in-stent thrombosis with occlusion beginning in the proximal RCA. In the RV branch, which was clearly visible on pre-interventional cath images, no contrast material filling could be delineated.
  • Fig. 3 Dual Energy iodine mapping showed a large area with decreased perfusion in the arterial phase in the inferoseptal wall extending from the base to the apex of the heart.
  • Fig. 4 Late enhancement was present in the inferoseptal wall corresponding to the perfusion defect in arterial phase.

In this case, Dual Energy coronary CTA was used to image a complication of interventional recanalization, i.e. acute in-stent thrombosis, while the initial clinical diagnosis of acute aortic dissection could reliably be ruled out. Read more
