超声心动图诊断新生儿先天性心脏病的临床价值

Clinical value of echocardiography in the diagnosis of neonatal congenital heart disease

目的探究超声心动图诊断新生儿先天性心脏病(CHD)的临床价值。方法选择1000例疑似CHD新生儿为研究对象,均实施超声心动图检查以及手术/心导管检查。以手术/心导管检查结果为金标准,分析超声心动图对新生儿CHD的诊断效能。结果1000例疑似CHD新生儿经超声心动图检查结果显示,881例(88.10%)未检出CHD,119例(11.90%)检出CHD,2例正常新生儿被误诊为室间隔缺损,6例漏诊,其余结果与手术/心导管检查结果一致。1000例疑似CHD新生儿经手术/心导管检查结果显示,125例检出CHD。超声心动图对新生儿CHD的诊断特异度为99.77%,灵敏度为93.60%,准确度为99.00%,阳性预测值为98.32%,阴性预测值为99.09%。结论超声心动图对新生儿CHD的诊断效能较高,可反映CHD新生儿的病情,以更好指导临床诊治。

Objective To explore the clinical value of echocardiography in the diagnosis of neonatal congenital heart disease(CHD).Methods A total of 1000 neonates suspected of CHD were taken as the research objects,and all of them were examined by echocardiography and surgery/cardiac catheterization.The diagnostic efficacy of echocardiography in neonatal CHD was analyzed based on the results of surgical/cardiac catheterization examination as the gold standard.Results The results of echocardiography in 1000 neonates with suspected CHD showed that CHD was not detected in 881cases(88.10%),and CHD was detected in 119 cases(11.90%).Two normal neonates were misdiagnosed as ventricular septal defect,6 cases were missed,and the other results were consistent with the results of surgery/cardiac catheterization.The results of surgical/cardiac catheterization in 1000 neonates with suspected CHD showed that CHD was detected in 125neonates.The specificity,sensitivity,accuracy,positive predictive value and negative predictive value of echocardiography in the diagnosis of neonatal CHD were 99.77%,93.60%,99.00%,98.32% and 99.09%,respectively.Conclusion Echocardiography has a high diagnostic efficiency for neonatal CHD,which can reflect the condition of CHD neonates and better guide clinical diagnosis and treatment.
