3.3.4. Predictors of mortality after transcatheter PIVSD closure
Individual analyses of predictors of mortality after transcatheter PIVSD closure based on the random effect showed good results. From four included articles (Zhang et al[16], Egbe et al[17], Assenza et al[18], Calvert et al[15]), CS (OR=3.607, 95%CI: 2.301-5.653; p=0.000, (shown in Fig. 3A))incline to add the risk of mortality, Zhang et al. and Calvert et al. studies show New York Heart Association (NYHA) class IV (OR=6.491, 95CI: 1.444-29.188; p=0.015, shown in Fig. 3B) was a predictor for TCC, time to PIVSD closure (OR=0.850, 95CI: 0.737-0.980; p=0.025, shown in Fig. 3C) was also the risk factors for PIVSD closure patients. There is no direct correlation between the defect size (OR=2.592, 95%CI: 0.380-17.661, shown in Fig. 3D) and death.
