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.
