Congenital coagulopathies—hemophilia A and B, von Willebrand disease, thrombocytopenia, and thrombocytopathies—are complex conditions that affect both boys and girls, and their families need to understand them in order to live safely and with peace of mind. When the diagnosis is made, parents are given precise medical explanations that are often difficult to visualize: invisible processes occurring inside the body, abstract hemostatic mechanisms, and treatments that act on systems the family cannot see.

The solution is an interactive simulator developed as a web app that translates the biomedical complexity of coagulation into a visual, dynamic, and understandable experience. It recreates the coagulation process using an animated platelet system, a dynamic fibrin network, and a functional representation of von Willebrand factor, allowing families to explore their child’s specific pathological scenario, observe the effect of treatments on the hemostatic response, and understand the reasoning behind each therapeutic decision. The interface is integrated via an iframe into the hospital’s digital platforms and is compatible with major browsers and devices, accessible anytime, anywhere.
