| Factor | VWF multimers |
| Description | An increased density of low-molecular-weight fractions of von Willebrand factor, which are suggestive of proteolytic degradation (p = 0.0081), was associated with decreased ADAMTS-13 activity, which was likely due to ADAMTS-13 consumption (71% of controls, p = 0.0029) and decreased von Willebrand factor: collagen binding (76% of controls, p = 0.0004). |
| Biomarker | NA |
| Classification | E2 (physiological factor - biochemical index) |

| Application | prognosis |
| Objective | To analyze the preoperative plasma antigenic concentration and activity of VWF and its main cleaving protease ADAMTS-13 in pediatric patients with cyanotic congenital heart disease undergoing surgical treatment and investigate possible correlations with postoperative bleeding. |
| p Value | 0.0081 |
