BAV bicuspid aortic valve, CoA coarctation, WSS wall shear stress, STJ sinotubular junction, AAo ascending aorta

Note that 11 BAV patients and 3 CoA-BAV patients were removed from the analysis at the STJ domain due to localized severe aliasing at the aortic root. Statistical significances are shown in bold numbers
