Rivaroxaban vs Warfarin in Acute Left Ventricular Thrombus Following Myocardial Infarction: RIVAWAR, An Open-Label RCT

JACC AdvPublished open-label, noninferiority, randomized controlled trial

Authors' conclusion

Rivaroxaban demonstrated similar efficacy to warfarin in treating post-MI LVT, with >95% resolution in both groups. Future multicenter trials with longer follow-up are needed to validate these findings (Rivaroxaban in Left Ventricular Thrombus; NCT04970576).
