Multicenter retrospective comparison of safety and efficacy among three antithrombotic regimens following TAVI

Each antithrombotic regimen presented unique clinical benefits and limitations. Transitioning from warfarin to rivaroxaban was associated with a significantly reduced risk of bleeding and shorter hospital stays. Transitioning from dual antiplatelet therapy to aspirin monotherapy significant prolonged APTT without increasing clinical bleeding events. These findings highlight the importance of tailored antithrombotic strategies to optimize post-TAVI outcomes.
