To assess whether a rivaroxaban-based anticoagulation strategy, following successful TAVR, compared to an antiplatelet-based strategy, is superior in reducing death or first thromboembolic events (DTE).
To assess the primary bleeding events (PBE) of the rivaroxaban-based strategy compared to an antiplatelet-based strategy, following TAVR.

Arm | Intervention/treatment |
---|---|
Experimental: Rivaroxaban (Xarelto, BAY59-7939)
Subjects were treated with Rivaroxaban (10mg once-daily) and ASA (75-100mg once-daily) within first 90 days after randomization. After 90 days, ASA was discontinued and rivaroxaban (10mg once-daily) was to be continued alone. In the event of NOAF (New Onset of Atrial Fibrillation), subjects should be switched to rivaroxaban (20/15mg once-daily) and ASA (75-100mg once-daily) within first 90 days. After 90 days, ASA was discontinued and rivaroxaban (20/15mg once-daily) was to be continued alone.

10mg OD (once-daily) Drug: Acetylsalicylic Acid (ASA) 75-100mg OD Drug: Rivaroxaban (Xarelto, BAY59-7939) In case of NOAF, 20/15 mg OD (once-daily) |
Active Comparator: Antiplatelet
Subjects were treated with clopidogrel (75mg once-daily) and ASA (75-100mg once-daily) within first 90 days after randomization. After 90 days, clopidogrel was discontinued and ASA (75-100mg once-daily) was to be continued alone. In the event of NOAF, subjects should start treatment of open-label VKA to target INR 2 to 3 (according to guidelines) and ASA (75-100mg once-daily) within first 90 days. After 90 days, ASA was discontinued and VKA was to be continued alone.
