Diagnosis
Fig. 1: MPR (Figs. 1a & 1b) and cVRT (Figs. 1c & 1d) images show a localized dissection flap (arrows) involving the RCA sinus of Vasalva. The RCA, originating off the false lumen, is severely stenosed at its ostium (dotted arrows), and well enhanced distally throughout its course.
Fig. 2: Curved MPR images show a severely stenosed RCA at its ostium (Fig. 2a, arrow) with a normal course. Mixed plaques in the proximal LAD and calcified plaques in the proximal Cx are seen causing no significant stenoses.
Fig. 3: A cVRT image shows an overview of the follow-up scan after the Bentall procedure. The graft with implanted aortic valve (white arrow) is in place and the re-implanted coronary arteries are patent. The CA and the SMA stem off the same branch (arrow). A hematoma (dotted arrow) on the right outside the graft is seen.
