Long Term Outcomes and Anticoagulation in Mitral Valve Surgery - A Report from the Society of Thoracic Surgeons Database
CONCLUSIONS: Anticoagulation was used in less than half of mitral valve surgery. In MVrep patients, warfarin was associated with increased bleeding and was not protective against either stroke or mortality. In BMVR patients, warfarin was associated with a modest survival benefit, increased bleeding and equivalent stroke risk. NOAC was associated with increased adverse outcomes.PMID:37308066 | DOI:10.1016/j.athoracsur.2023.05.025

Risk of Stroke and Major Bleeding with Vitamin-K Antagonist Use after Mitral Valve Repair
CONCLUSIONS: Our study suggests that VKA after MVr does not reduce risk of cerebral embolic events but is associated with increased risk of major bleeding events.PMID:36223805 | DOI:10.1016/j.athoracsur.2022.09.038

Direct oral anticoagulation in atrial fibrillation and heart valve surgery-a meta-analysis and systematic review
CONCLUSION: Cumulative data analysis reveals that DOAC may provide an effective and safe alternative to VKA in patients with AF after surgically implanted bioprosthetic heart valves or repair with AF. Within a relatively heterogeneous study population, this meta-analysis shows a risk reduction of major bleedings and thromboembolic stroke or systemic embolisms for DOAC.PMID:35481366 | DOI:10.1177/17539447221093963

Non-Vitamin K Antagonists versus Warfarin in Patients with Atrial Fibrillation and Bioprosthetic Valves: a Systematic Review and Meta-Analysis
Patients with bioprosthetic heart valves and valve repair with concomitant atrial fibrillation are at an increased risk of thromboembolic events.1-5 Until recently, there was a paucity of randomized data to guide the optimal anticoagulation strategy in this patient population. In a prior meta-analysis of 4 randomized studies in patients with atrial fibrillation and valvular heart disease, excluding significant mitral stenosis and mechanical valves, there was a significant reduction in the risk of stroke or systemic embolism with non-vitamin K antagonist oral anticoagulants (NOACs) vs.

Comparison of outcomes of direct-acting oral anticoagulants vs. vitamin K antagonists in patients with bioprosthetic heart valves or valve repair: a systematic review and meta-analysis
CONCLUSIONS: Findings suggest that the use DOACs in patients with AF with bioprosthetic valve replacement or repair is comparatively better than vitamin K antagonists in reducing the risk of bleeding and thrombo-embolic events. Future studies with a randomized design and larger sample sizes are needed to further substantiate these findings.PMID:34355372 | DOI:10.26355/eurrev_202108_26457
