Fig. 1. (A) Scatter-dot graph indicating correlation between baseline PWV values and mean aortic gradient, AVA, and AVA index. Values are shown as correlation coefficients (r); correlation is significant at the 0.05 level. (B) Scatter-dot graph showing the linear correlation between the baseline AVA index values and the change in aortic stiffness (defined as baseline PWV − postoperative PWV) in patients undergoing aortic valve replacement. Values are shown as correlation coefficients (r); correlation is significant at the 0.05 level. AVA: aortic valve area; PWV: pulse wave velocity.
