[Angiology and hemostasis : what's new in 2022].

In this article, we have selected four topics that particularly caught our attention during the year 2022, and which are related to anticoagulation, its bleeding complications, and hemophilia. Thus, we discuss the issue of the treatment with rivaroxaban of atrial fibrillation associated with rheumatic valvulopathy, which has been studied in a randomized trial, the intensity of thromboprophylaxis in COVID outpatients and inpatients, and the bleeding risk of anticoagulation in patients with cerebral tumors. Finally, recent data on gene therapy in severe hemophilia A, an upcoming treatment, are discussed.
