Correlations of the ratio of peak wall shear stress (WSS) in exercise to rest (WSS_Ex:Rest) in the ascending aorta (AAo) and descending aorta (DAo) with aorta size mismatch (D_AAo/D_DAo). a AAo peak WSS_Ex:Rest had a negative correlation with D_AAo/D_DAo. b DAo peak WSS_Ex:Rest had positive correlation with D_AAo/D_DAo. c Examples are shown of an aorta with a large D_AAo/D_DAo (red box) leading to a small change in peak WSS in the AAo and a large change in the DAo, while an aorta with a more normal, small size mismatch (green box) leads to a large change in peak WSS in the AAo and small change in the DAo
