Systematic review and meta-analysis of surgical ablation for atrial fibrillation during mitral valve surgery.

摘要: Background: Surgical ablation has emerged as an acceptable treatment modality for patients with atrial fibrillation (AF) undertaking concomitant cardiac surgery. However, the efficacy of surgical in patient populations undergoing mitral valve surgery is not well established. The present meta-analysis aims to establish current Level IA evidence on clinical outcomes versus no ablative AF surgery. Methods: Electronic searches were performed using six databases from their inception September 2013, identifying all relevant randomized controlled trials (RCTs) comparing Data extracted and analyzed according predefined endpoints. Results: Nine RCTs identified inclusion analysis. number sinus rhythm (SR) was significantly improved group non-ablation at discharge. This effect SR remained follow-up periods until >1 year. Results indicated that there significant difference between terms 30-day mortality, all-cause pacemaker implantation, stroke, thromboembolism, tamponade, reoperation bleeding myocardial infarction. Conclusions: demonstrate addition leads a higher rate patients, increase rates stroke thromboembolism. Further research should be directed correlating different subtypes cerebrovascular events long-term follow-up.
