Visit based variation in maximum aortic diameter for three aortic phenotypes in TS comprised of aortic valve regurgitation (Subject 1), elongation of the transverse aortic arch (Subject 9) and aortic coarctation (Subject 7). Visit 1 – solid blue line, Visit 2 – solid red line, Visit 3 – solid black line. Diamond markers indicate corresponding manual measures. Data at locations of the inominate artery (IA), left common carotid artery (LCCA), left subclavian artery (LSCA) (shaded in black) excluded from analysis. All values are in mm. Aortas for the three visits aligned at the branches
