RESUMEN
Objective To evaluate the diagnostic accuracy of two dimensional echocardiography combining with enhanced flow (e-flow) imaging for fetal heart malformation.Methods 1580 cases were screened for fetal heart malformation.The diagnostic accuracy was evaluated by comparing the results fetal echocardiography with those of postpartum echocardiography,surgery or autopsy.Results Antepartum and postpartum data were obtained in 1286 of the 1580 fetuses (81.39％).Among the 1286 cases,the sensitivity,specificity,mistake diagnostic rate,omission diagnostic rate was 98.0 ％,99.3 ％,2.0 ％,0.7％,respectively.The consistency evaluation of fetal heart malformation by two dimensional echocardiography combining with e-flow concluded that the valve of Kappa was 0.970 (P =0.000).Conclusions Two dimensional echocardiography combining with e-flow is an accurate and reliable method for diagnosing fetal heart malformation,it has a high sensitivity and specificity.
