Is this trial a fit for you?

Likely a good fit

What this trial studies

This observational study aims to investigate the frequency and characteristics of arterial and venous thromboembolic events, as well as atrial fibrillation, in adult patients with von Willebrand disease in the French West. It will utilize a retrospective multicenter approach, analyzing data from patients who have experienced thrombotic events while being treated at designated medical centers. The study seeks to fill the gap in existing literature regarding the management of thrombotic risks in this population, given their unique bleeding risk profile.

Why it matters

Potential benefit: If successful, this study could improve the understanding and management of thrombotic events in patients with von Willebrand disease, leading to better patient outcomes.

How similar studies have gone: While there is limited data on this specific population, similar studies on thromboembolic events in other bleeding disorders have shown promising results, indicating potential for valuable insights.
