Abstract 14414: Bioprosthetic Valve Thrombosis: Different Time to Response to Warfarin in Mitral and Aortic Valves

Background: Warfarin is known to be effective in the treatment of bioprosthetic valve thrombosis (BPVT). However, the time-course of response to anticoagulation has not been fully characterized. Hypothesis: We hypothesized that response to warfarin can differ depending on valve position. Methods: We retrospectively identified 45 patients with BPVT diagnosis between 2002 and 2019 that involved either the mitral (MV) or the aortic valve (AV)...
