Fig 1.
Nitric oxide synthase 3 (NOS3) gene expression (n ¼ 10–11 per valve type, per right [R], left [L], and noncoronary (N) sinus regions). Values are normalized to platelet endothelial cell adhesion molecule-1 expression. The error bars indicate SD. *p < 0.05 (BAV = bicuspid aortic valve; TAV = tricuspid aortic valve.)
