case_images: All cases were identified as QAV by MDCT: two were type C, two were type E, and the remaining one was type B (Figure 2).
case_images: The dimensions of the aortic sinus, coronary artery, and valve leaflet of the QAVs of five patients were measured by CTA. (SOV) Measurements of the anticipated morphology of the implanted valve after release at the aortic sinus level and the diameters of right coronary sinus (RC) and left coronary sinus (LC); (RA) Assessment of right coronary artery (RCA) occlusion risk, including the heights of the RCA and the lengths of the adjacent valve leaflet; (LA) Assessment of left coronary artery (LCA) occlusion risk, including the heights of the LCA and the lengths of the adjacent valve leaflet.
