Analysis pertains to BAV cohort only. Pearson correlation used when both variables were parametric, Spearman's correlation used when at least 1 variable was non-parametric. AA1, proximal to first aortic branch; BAV, bicuspid aortic valve; EL_index, peak systolic viscous energy loss normalized to net flow; MAA, mid-ascending aorta; P, P-value; PD, pressure drop; PD_sys, peak systolic pressure drop; R, correlation coefficient; SOV, sinuses of Valsalva; WSS_A,avg, circumference-averaged peak systolic axial wall shear stress, WSS_A,max, localized peak systolic axial wall shear stress, WSS_C,avg, circumference-averaged peak systolic circumferential wall shear stress; WSS_C,max, localized peak systolic circumferential wall shear stress; WSS_M,avg, circumference-averaged peak systolic net magnitude wall shear stress; WSS_M,max, localized peak systolic net magnitude wall shear stress.
