Objectives: While 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. Methods: We 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. Results: We 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%). Conclusions: Our 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.

ObjectiveCurrent guidelines endorse the use of non-vitamin K antagonist oral anticoagulants (NOACs) in patients with atrial fibrillation (AF). However, little is known about their safety and efficacy in valvular heart disease (VHD). Similarly, there is a paucity of data regarding NOACs use in patients with a bioprosthetic heart valve (BPHV). We, therefore, performed a network meta-analysis in the subgroups of VHD and meta-analysis in patients with a BPHV.MethodsPubMed, Cochrane and Embase were searched for randomised controlled trials. Summary effects were estimated by the random-effects model. The outcomes of interest were a stroke or systemic embolisation (SSE), myocardial infarction (MI), all-cause mortality, major adverse cardiac events, major bleeding and intracranial haemorrhage (ICH).ResultsIn patients with VHD, rivaroxaban was associated with more ICH and major bleeding than other NOACs, while edoxaban 30 mg was associated with least major bleeding. Data combining all NOACs showed a significant reduction in SSE, MI and ICH (0.70, [0.57 to 0.85; p<0.001]; 0.70 [0.50 to 0.99; p<0.002]; and 0.46 [0.24 to 0.86; p<0.01], respectively). Analysis of 280 patients with AF and a BPHV showed similar outcomes with NOACs and warfarin.ConclusionsNOACs performed better than warfarin for a reduction in SSE, MI and ICH in patients with VHD. Individually NOACs performed similarly to each other except for an increased risk of ICH and major bleeding with rivaroxaban and a reduced risk of major bleeding with edoxaban 30 mg. In patients with a BPHV, results with NOACs seem similar to those with warfarin and this needs to be further explored in larger studies.

Efficacy And Safety

Background: Direct oral anticoagulants (DOACS) are approved for use in non-valvular atrial fibrillation (AF). This systematic review and meta-analysis aimed to evaluate the efficacy and safety of DOACs vs. warfarin and update the evidence for treatment of AF and valvular heart disease (VHD).Methods: We identified randomized clinical trials (RCTs) and post-hoc analyses comparing the use of DOACS and Warfarin in AF and VHD, including biological and mechanical heart valves (MHV), updating from 2010 to 2020. Through systematic review and meta-analysis, by using the “Rev Man” program 5.3, the primary effectiveness endpoints were stroke and systemic embolism (SE). The primary safety outcome was major bleeding, while the secondary outcome included intracranial hemorrhage. We performed prespecified subgroup analyses. Data were analyzed by risk ratio (RR) and 95% confidence interval (CI) and the I-square (I2) statistic as a quantitative measure of inconsistency. Risk of bias and methodological quality assessment of included trials was evaluated with the modified Cochrane risk-of-bias tool.Results: We screened 326 articles and included 8 RCTs (n = 14.902). DOACs significantly reduced the risk of stroke/SE (RR 0.80, 95% CI: 0.68–0.94; P = 0.008; moderate quality evidence; I2 = 2%) and intracranial hemorrhage (RR 0.40, 95% CI: 0.24–0.66; P = 0.0004; I2 = 49%) with a similar risk of major bleeding (RR 0.83, 95% CI: 0.56–1.24; P = 0.36; I2 = 88%) compared to Warfarin.Conclusions: In this update, DOACs remained with similar efficacy and safety compared to warfarin in thromboprophylaxis for AF and VHD.

Valvular heart disease and atrial fibrillation often coexist. Oral vitamin K antagonists have represented the main anticoagulation management for antithrombotic prevention in this setting for decades. Novel direct oral anticoagulants (DOACs) are a new class of drugs and currently, due to their well-established efficacy and security, they represent the main therapeutic option in non-valvular atrial fibrillation. Some new evidences are exploring the role of DOACs in patients with valvular atrial fibrillation (mechanical and biological prosthetic valves). In this review we explore the data available in the medical literature to establish the actual role of DOACs in patients with valvular heart disease and atrial fibrillation.

Direct oral anticoagulants (DOACs) have been demonstrated to be more effective and safer than vitamin-K antagonist (VKA) for stroke prevention in patients with nonvalvular atrial fibrillation (AF). This meta-analysis aims to assess the effect of DOACS vs. VKA in patients ≥ 80 and AF. Primary endpoints were stroke or systemic embolism and all-cause death. Secondary endpoints included major bleeding, intracranial bleeding, and gastrointestinal bleeding. A random-effects model was selected due to significant heterogeneity. A total of 147,067 patients from 16 studies were included, 71,913 (48.90%) treated with DOACs and 75,154 with VKA (51.10%). The stroke rate was significantly lower in DOACs group compared with warfarin group (Relative risk (RR): 0.72; 95% confidence interval (CI): 0.63–0.82; p < 0.001). All-cause mortality was significantly lower in DOACs group compared with warfarin group (RR: 0.82; 95% CI: 0.70–0.96; p = 0.012). Compared to warfarin, DOACs were not associated with reductions in major bleeding (RR: 0.85, 95% CI 0.69–1.04; p = 0.108) or gastrointestinal bleeding risk (RR: 1.08, 95% CI 0.76–1.53; p = 0.678) but a 43% reduction of intracranial bleeding (RR: 0.47, IC 95% 0.36–0.60; p < 0.001) was observed. Our meta-analysis demonstrates that DOACs are effective and safe with statistical superiority when compared with warfarin in octogenarians with AF.
