Abstract
Abstract
Background
Percutaneous left atrial appendage closure (LAAC) has emerged as a non-pharmacological alternative to long-term oral anticoagulation with vitamin K antagonists (VKA) or direct oral anticoagulants (DOAC) for stroke prevention in patients with non-valvular atrial fibrillation.
Methods
We searched PubMed and Embase for randomized controlled trials (RCT) comparing 3 different strategies (DOAC vs VKA, LAAC vs VKA, LAAC vs DOAC). Treatment effects were calculated from a network meta-analysis using random-effect model with inverse-variance weighting. The ranking probability of each treatment was based on SUCRA. The primary endpoint was a composite of stroke or systemic embolism.
Results
A total of 7 RCTs and 73,106 patients were included. The risk of the primary endpoint was comparable between LAAC and oral anticoagulation (LAAC vs VKA: OR 0.87, 95% CI 0.55-1.39; LAAC vs DOAC: OR 1.00, 95% CI 0.62-1.61) while it was reduced with DOAC vs VKA (OR 0.87, 95% CI 0.77-0.98). Major bleeding was numerically lower with LAAC vs VKA (OR 0.74, 95% CI 0.48-1.16) and similar between LAAC and DOAC (OR 0.93, 95% CI 0.61-1.42). LAAC significantly reduced the risk of mortality compared with both VKA (OR 0.52, 95% CI 0.37-0.73) and DOAC (OR 0.58, 95% CI 0.42-0.82). The probability of being the best treatment for stroke or systemic embolism prevention was similar for DOAC (51%) and LAAC (48%) whereas LAAC ranked as best treatment for reducing major bleeding (64%) and mortality (100%).
Conclusions
LAAC is a safe and effective alternative to DOAC and VKA for the secondary prevention of patients with non-valvular atrial fibrillation.
