The RIVER trial pre-specified analysis presented at ESC 2022 aimed to test the efficacy/safety of rivaroxaban compared to warfarin in patients with atrial fibrillation (AF) and bioprosthetic mitral valves, according to time of valve implantation. In this touchCARDIO interview, we speak with Professor Renato Lopes (Duke University Medical Center, Durham, NC, USA) to discuss non-vitamin K antagonist oral anticoagulants (NOACs), also known as direct oral anticoagulants (DOACs), in patients with AF and bioprosthetic valves as well as the RIVER trial and what questions remain unanswered that require further studies.
The abstract entitled ‘RIVER: Rivaroxaban for Valvular Heart Disease and Atrial Fibrillation’ was presented at the European Society of Cardiology (ESC) Congress 2022, 26 – 29 August 2022.
