The objective of the INVICTUS study was to determine if:
1. In patients with rheumatic valvular heart disease (RVHD) and who are in atrial fibrillation or flutter (AF/flutter) and have other stroke risk factors, rivaroxaban is non-inferior to vitamin K antagonists (VKAs) for prevention of stroke or systemic embolism.
2. In patients with RVHD, either with AF/flutter but unsuitable for VKA therapy, or with sinus rhythm but with high risk, rivaroxaban is superior to aspirin for prevention of stroke or systemic embolism.
Stroke and systemic embolism.
This research program was comprised of running concurrently two randomized, parallel group, open-label clinical trials, and a multi-center registry for RVHD.
