The desmopressin enhances von Willebrand factor indices as compared with placebo in patients with severe aortic stenosis undergoing valve replacement. Data are presented as means and 95% confidence intervals. (Ag = antigen; CBA = collagen binding activity; GpIb = glycoprotein Ib binding activity; RCo = ristocetin cofactor activity; VWF = von Willebrand factor; ***p < between groups; ■ = desmopressin; ○ = placebo.)

The desmopressin rapidly normalizes primary hemostasis as measured by the platelet function analyzer in patients with severe aortic stenosis undergoing valve replacement. Data are presented as means and 95% confidence intervals. (***p < between groups; ■ = desmopressin; ○ = placebo.)
