UNASSIGNED: Background   The outcomes of @entity955 ( @entity955 ) between biatrial maze (BAM) and left atrial maze (LAM) are still controversial. The purpose of this study was to compare the clinical and rhythm outcomes between BAM and LAM in @entity1 with @entity955 . Methods   Electronic databases and article references were systematically searched (1990-2014) to access relevant studies. Odds ratio (OR) and @entity353 ( @entity353 ) with 95% confidence interval (CI) were reported. Results   Fourteen studies with 2,075 @entity1 were finally involved in the present meta-analysis. The rate of restored sinus rhythm (SR) was similar in BAM and LAM groups (OR: 1.25, 95% CI: 0.91-1.72, p   =   0.163). BAM reduced the prevalence of @entity956 during follow-up (OR: 0.12, 95% CI: 0.01-0.96, p   =   0.046). Compared with BAM, LAM shorten aortic cross-clamping time ( @entity353   =   9.05 minutes, 95% CI: 1.28-16.82, p   =   0.023) and cardiopulmonary bypass time ( @entity353   =   20.21 minutes, 95% CI: 7.40-33.03, p   =   0.002). No significant difference was found between groups in the risk of @entity204 (OR: 1.22, 95% CI: 0.70-2.14, p   =   0.233), cerebrovascular events (OR: 1.44, 95% CI: 0.51-4.06, p   =   0.493), and reoperation for @entity548 (OR: 1.34, 95% CI: 0.70-2.55, p   =   0.374). However, the risk for implantation of permanent pacemaker was significantly higher in BAM group (OR: 2.60, 95% CI: 1.09-6.20, p   =   0.031). Conclusion   No significant difference was found between BAM and LAM in the rate of restored SR, the risk of @entity204 , cerebrovascular events, and reoperation for @entity548 . BAM is superior to LAM in reducing the prevalence of @entity956 during follow-up, but LAM shortens the aortic cross-clamping time and cardiopulmonary bypass time, and decreases the risk of permanent pacemaker implantation.
