对502例有先天性心脏病风险的孕16～38周的胎儿进行了胎儿超声波心动扫描检查,凡结果显示心脏异常的胎儿全部进行胎儿核型分析,之后再分别通过尸检报告、产后超声波心动扫描及心血管造影印证上述诊断。 502例中有469例获得完整跟踪检查结果,其中34例诊断为心脏异常,2例假阳性和2例假阴性结果,31例先天性心脏病被进一步的检验证实。因此本中心所做胎儿超声波心动扫描诊断其灵敏度和特异性分别为93.9％(31/31+2)和99.5％(434/434
Fetal echocardiography was performed on 502 fetuses with gestational age of 16-38 weeks at risk of congenital heart disease. All fetal fetuses with abnormal cardiac findings were subjected to fetal karyotyping, and then were respectively subjected to autopsy reports. Postnatal echocardiography And cardiovascular imaging confirmed the above diagnosis. Of the 502 patients, 469 had complete follow-up results, of which 34 were diagnosed with cardiac abnormalities, 2 false positives and 2 false negatives, and 31 congenital heart disease were confirmed by further testing. Therefore, the center made by fetal echocardiography diagnostic sensitivity and specificity were 93.9% (31/31 +2) and 99.5% (434/434
