Abstract:
This systematic review and meta‐analysis compares direct oral anticoagulants (DOACs) versus vitamin K antagonists (VKAs) in patients with atrial fibrillation and bioprosthetic valve replacement or repair (BVR). Background The optimal anticoagulation therapy for patients with atrial fibrillation and a history of bioprosthetic valve replacement or repair (BVR) is not well understood. Methods We performed a systematic literature review to identify clinical studies that compared anticoagulation therapies for patients with atrial fibrillation and BVR. The primary outcomes of stroke, major bleeding, and mortality were reported as random effects risk ratio (RR) with 95% confidence interval. No prior ethical approval was required since all data is public. Results Our search yielded 101 potential studies. We included six studies reporting on 1911 patients. There was a lower risk of stroke and major bleeding in patients with atrial fibrillation after BVR treated with DOACs when compared to VKAs with risk ratios of 0.44 (95% CI 0.24–0.82, p 〈 0.01) and 0.53 (95% CI 0.34–0.83, p 〈 0.01), respectively. There was no statistically significant difference in mortality between patients with atrial fibrillation after BVR treated with DOACs compared to patients treated with VKAs with a risk ratio of 1.12 (95% CI 0.73–1.74, p = 0.60). Conclusion This systematic review and meta‐analysis suggests that DOACs are superior to VKAs with respect to stroke and major bleeding in patients with atrial fibrillation and BVR.
