Fig. 2

Linear regression analysis demonstrating correlation between 3-dimensional (3D) thoracic aorta peak principal strain amplitude (PPSA) using ECG-gated CTA and measures of aortic valve stenosis severity. Correlations are depicted for the ascending aorta 3D PPSA and aortic valve area (a) and mean aortic valve pressure gradient (b), and for the global thoracic aorta 3D PPSA and aortic valve area (c) and mean aortic valve pressure gradient (d). Dotted lines indicate 95% confidence intervals. R: Pearson Correlation Rank
