Edoxaban Compared to Standard Care After Heart Valve Replacement Using a Catheter in Patients With Atrial Fibrillation (ENVISAGE-TAVI AF)
Purpose
When the upper chambers of a person's heart receive or generate irregular electrical signals, it causes abnormal rhythm in the heartbeat. This is called atrial fibrillation. Atrial fibrillation goes along with blood clots that may cause mainly strokes and less often other diseases, such as a heart attack. Some patients with atrial fibrillation have other heart disease, such as heart valves that may need to be replaced using catheters. Often doctors give patients drugs that reduce those blood clots. These are either vitamin K antagonist (VKA) or direct anticoagulants, such as edoxaban. In these patients, it is unclear which of the drugs is better for reducing stroke without increasing severe bleedings.

Detailed Description
Use of Edoxaban in patients with atrial fibrillation (AF) and indication to chronic oral anticoagulation (OAC) after transcatheter aortic valve implantation (TAVI) Objective: - To assess the effect of Edoxaban versus vitamin K antagonist (VKA) on net adverse clinical events (NACE), i.e., the composite of all-cause death, myocardial infarction (MI), ischemic stroke, systemic thromboembolism (SEE), valve thrombosis, and major bleeding (International Society on Thrombosis and Haemostasis [ISTH] definition). - To assess the effect of Edoxaban versus VKA on major bleeding (ISTH definition).
