Note that there is a considerable literature on using these agents in the prevention of thromboembolism associated with atrial fibrillation and mechanical heart valves. As these conditions are out of the purview of HemOnc.org, this page primarily focuses on the prevention and treatment of venous thromboembolism (VTE).

  • We have moved How I Treat articles to a dedicated page.
