Abstract
Methods and Results: This post-hoc subgroup analysis of a multicenter, prospective, observational registry (BPV-AF Registry) aimed to compare DOACs and warfarin in AF patients with an aortic BPV. The primary outcome was a composite of stroke, systemic embolism, major bleeding, heart failure requiring hospitalization, all-cause death, or BPV reoperation. The analysis included 479 patients (warfarin group, n=258; DOAC group, n=221). Surgical aortic valve replacement was performed in 74.4% and 36.7% of patients in the warfarin and DOAC groups, respectively. During a mean follow up of 15.5 months, the primary outcome occurred in 45 (17.4%) and 32 (14.5%) patients in the warfarin and DOAC groups, respectively. No significant difference was found in the primary outcome between the 2 groups (adjusted hazard ratio: 0.88, 95% confidence interval: 0.51–1.50). No significant multiplicative interaction was observed between the anticoagulant effects and type of aortic valve procedure (P=0.577).
