CDH5 and aortic stenosis: In a subgroup of aortic stenosis valvular patients where echocardiac valvular gradient (mmHg) and valvular area (cm2) were available, there was not a significant correlation among these parameters and the abundance of CD34+/CD144+ (r2 = 0.021, P = 0.41 for mean gradient and r2 = 0.015 and P = 0.48 for valve area, respectively).
