ObjectivesWhile the use of novel oral anticoagulants (NOACs) has been approved in the treatment of non-valvular atrial fibrillation (NVAF), we are lacking studies on individual NOACs in NVAF with valvular heart disease (VHD) including bio-prosthetic valve and valve repair. We aimed to determine the efficacy and safety of rivaroxaban compared to warfarin in prevention of thromboembolism in patients with NVAF with VHD. MethodsWe searched PubMed, MEDLINE, and EMBASE including only RCTs and Cohort studies from inception till April 2021. Eligible studies compared rivaroxaban with warfarin in patients with NVAF with VHD. We excluded patients with valvular AF. We used Review Manager (version 5.4, Cochrane Collaboration, Oxford, UK) applying the Mantel-Haenszel test and followed PRISMA guidelines. Risk ratio (RR) and 95% confidence intervals (CIs) were estimated using a random-effects method and heterogeneity using I squared test. ResultsWe had total of 23136 participants in both groups. Our results showed stroke and systemic thromboembolism in 88 of 4258 (2.06%) patients in the rivaroxaban group compared to 351 of 18878 (1.85%) patients in the warfarin group (RR 0.76; 95% CI, 0.55, 1.06; heterogeneity I2 = 35%, P = 0.10), major bleeding in 247 of 4258 (5.8%) patients in the rivaroxaban group compared to 270 of 18879 (1.4%) patients in the warfarin group (HR 1.68; 95% CI, 0.59, 4.77; heterogeneity I2 = 97%) and intracranial hemorrhage in 24 out of 2583 (0.9%) patients in the rivaroxaban group compared to 35 of 2160 (1.6%) in warfarin group (HR 0.49; 95% CI, 0.16, 1.56; heterogeneity I2 = 70%). ConclusionsOur results show that rivaroxaban is comparable to warfarin in prevention of stroke and systemic thromboembolism in patients with NVAF with VHD. Rivaroxaban is also comparable to warfarin in bleeding risks in these patients. REGISTRATION NUMBERCRD42021222490
