Figure 1 Effect of AV Morphology on Ascending Aortic Diameters in Turner Syndrome

(A) Measurements were at the annulus, midpoint of the sinuses of Valsalva, sinotubular junction (STJ), and ascending aorta (Asc) 1 cm above the STJ. The box includes the 25th to 75th percentiles and whiskers include the 10th to 90th percentiles. The horizontal line in the box indicates the median, and all observations less than the 10th and greater than the 90th percentiles are shown as points. (B) Correlation between Asc diameter measured by echocardiography (Echo AD) and magnetic resonance imaging (MR AD). The echocardiography measurement was 1 cm above the STJ, and the magnetic resonance imaging measurement was at the level of the right pulmonary artery. The distance between these 2 points is 5 to 10 mm. BAV = bicuspid aortic valve; TAV = tricuspid aortic valve.
