Résumé
Combined catheter ablation (CA) with percutaneous left atrial appendage closure (LAAC) may produce comprehensive treatment for atrial fibrillation (AF) whereby rhythm control is achieved and stroke risk is reduced without the need for chronic oral anticoagulation. However, the efficacy and safety of this strategy is still controversial. This meta-analysis was reported according to the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Medline, Scopus, and Cochrane Central Register of Controlled Trials were systematically searched to identify relevant studies. The risk of bias was assessed using the Modified Newcastle-Ottawa scale and Cochrane risk of bias tool. Eligible studies reported outcomes in patients with AF who underwent combined CA and LAAC vs CA alone. Studies performing CA without pulmonary vein isolation were excluded. Eight studies comprising 1878 patients were included (2 RCT, 6 observational). When comparing combined CA and LAAC vs CA alone, pooled results showed no difference in arrhythmia recurrence (risk ratio (RR) 1.04; 95% confidence interval (CI) 0.82-1.33), stroke or systemic embolism (RR 0.78; 95% CI 0.27-2.22), or major periprocedural complications (RR 1.28; 95% CI 0.28-5.89). Total procedure time was shorter with CA alone (mean difference 48.45 min; 95% CI 23.06-74.62). Combined CA with LAAC for AF is associated with similar rates of arrhythmia-free survival, stroke, and major periprocedural complications when compared to CA alone. A combined strategy may be as safe and efficacious for patients at moderate to high risk for bleeding events to negate the need for chronic oral anticoagulation.

BACKGROUND
BACKGROUND
Combined catheter ablation (CA) with percutaneous left atrial appendage closure (LAAC) may produce comprehensive treatment for atrial fibrillation (AF) whereby rhythm control is achieved and stroke risk is reduced without the need for chronic oral anticoagulation. However, the efficacy and safety of this strategy is still controversial.
METHODS
METHODS
This meta-analysis was reported according to the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Medline, Scopus, and Cochrane Central Register of Controlled Trials were systematically searched to identify relevant studies. The risk of bias was assessed using the Modified Newcastle-Ottawa scale and Cochrane risk of bias tool. Eligible studies reported outcomes in patients with AF who underwent combined CA and LAAC vs CA alone. Studies performing CA without pulmonary vein isolation were excluded.
RESULTS
RESULTS
Eight studies comprising 1878 patients were included (2 RCT, 6 observational). When comparing combined CA and LAAC vs CA alone, pooled results showed no difference in arrhythmia recurrence (risk ratio (RR) 1.04; 95% confidence interval (CI) 0.82-1.33), stroke or systemic embolism (RR 0.78; 95% CI 0.27-2.22), or major periprocedural complications (RR 1.28; 95% CI 0.28-5.89). Total procedure time was shorter with CA alone (mean difference 48.45 min; 95% CI 23.06-74.62).
CONCLUSION
CONCLUSIONS
Combined CA with LAAC for AF is associated with similar rates of arrhythmia-free survival, stroke, and major periprocedural complications when compared to CA alone. A combined strategy may be as safe and efficacious for patients at moderate to high risk for bleeding events to negate the need for chronic oral anticoagulation.
