AS overrides BAV-specific WSS patterns; leaves open whether 4D-flow WSS refines dilatation risk stratification beyond valve phenotype and stenosis.
Does aortic valve stenosis alter regional aortic wall shear stress independent of aortic valve phenotype?
Aortic valve stenosis significantly increases regional aortic wall shear stress, overriding the distinct hemodynamic patterns typically associated with bicuspid and tricuspid aortic valve phenotypes.
Ooij et al. (2017) studied this question.
