Full Study Name

Edoxaban Versus Standard of Care and their Effects on Clinical Outcomes in Patients Having Undergone Transcatheter Aortic Valve Implantation—in Atrial Fibrillation (IRB no. 49605)


The purpose of this study is to examine the safety and effectiveness of an anticoagulant drug called edoxaban versus other anticoagulants (blood thinning medication) in patients who have undergone transcatheter aortic valve implantation (TAVI) and who suffer from atrial fibrillation (irregular heart rate). 

There are two main types of blood thinners: anticoagulants and antiplatelet drugs. Anticoagulants include edoxaban or vitamin-K antagonists (VKA) such as warfarin. Antiplatelet drugs include aspirin and P2Y12 inhibitors. Researchers will compare edoxaban to the standard treatment of a VKA to learn which is more effective in this patient population. Participants will be randomly assigned to one of two study groups. The first group will receive edoxaban, and the second group will receive routine VKA. 

Edoxaban is approved by the U.S. Food and Drug Administration (FDA) for use in certain patients with atrial fibrillation, but it is not approved for patients with atrial fibrillation who undergo TAVI.
