Correlation between hemodynamic and anatomic aortic stenosis severity according to blood pressure and systemic arterial compliance status. (A) The correlation between aortic valve calcification density (normalized by square root [Sqrt]) and mean gradient and (B) the correlation between aortic valve calcification density (normalized by square root [Sqrt]) and peak aortic jet velocity. Note that both peak aortic jet velocity and mean gradient are highly influenced by hypertension and reduced systemic arterial compliance compared with normotensive patients with normal arterial compliance. Moreover, the decrease in mean gradient and peak aortic jet velocity is more important with more severe AS.
