为尽早确诊胎儿先天性心脏病(简称先心病),对200例胎儿进行B超心动图检查,发现心脏异常36例(18%),其中先心病26例(13％)。测定有高危因素的103例孕母血清风疹病毒抗体IgM,10例阳性(9.7％),其中7例胎儿有先心病(70%),其灵敏度为70％,特异度为92.3％,可做为胎儿先心病的筛查方法。两项检查合用,可提高胎儿先心病的诊断水平。同时提示胎儿超声心动图检查中增加卵圆孔直径和血流的评定可作为房间隔缺损的诊断标准。
In order to diagnose fetal congenital heart disease as soon as possible (referred to as congenital heart disease), 200 fetuses were examined by B-cardioembolism and 36 cases (18%) had cardiac abnormalities, including 26 cases (13%) with congenital heart disease. 103 cases of high risk pregnancy serum IgM antibody IgM, 10 cases were positive (9.7%), of which 7 cases of fetal congenital heart disease (70%), the sensitivity was 70%, the specificity of 92.3%, as Fetal CHD screening method. Two checks combined, can improve the diagnosis of fetal congenital heart disease. At the same time prompted fetal echocardiography increased foramen ovale diameter and blood flow assessment can be used as atrial septal defect diagnostic criteria.
