DangasTranscatheter aortic valve implantation, also called transcatheter aortic valve replacement (TAVR), is the treatment of choice for patients with severe aortic stenosis and intermediate to high operative risk. A significant portion of TAVR patients have atrial fibrillation (AF) requiring chronic oral anticoagulation. In moderate- to high-risk AF patients, the direct factor Xa inhibitor edoxaban is noninferior to vitamin K antagonists (VKAs) for prevention of stroke or systemic embolism with less bleeding and cardiovascular deaths. ENVISAGE-TAVI AF (NCT02943785) is a multinational, multicenter, prospective, randomized, open-label, blinded end point evaluation study comparing edoxaban to VKA-based therapy in approximately 1,400 patients with an indication for chronic oral anticoagulation after successful transfemoral TAVR. The coprimary end points are to assess the differential effects of the 2 treatments (a) on net adverse clinical events (the composite of all-cause death, myocardial infarction, ischemic stroke, systemic thromboembolism, valve thrombosis, and major bleeding events) and (b) on major bleeding. Twelve hours to 5 days after successful TAVR, patients will be randomized...
