目的探讨超声心脏轴测定联合心脏四腔观法在先天性心脏病诊断中的应用价值。方法选取2014年11月至2016年1月来辽宁省沈阳市妇婴医院检查的80例妊娠19周以上的孕妇作为研究对象,应用超声心脏轴测定联合心脏四腔观法确诊胎儿是否存在先天性心脏病,随后根据产儿尸检或随访对其进行验证,分析其灵敏度等指标。结果超声心脏轴测定联合四腔观检测诊断胎儿先天性脏病的灵敏度显著高于单纯使用四腔观法,差异有统计学意义(χ~2=34.028,P=0.000);先天性心脏病胎儿心轴异常所占比例明显高于正常胎儿,差异有统计学意义(P<0.05);先天性心脏病胎儿的心轴角度明显大于正常胎儿,差异有统计学意义(P<0.05)。结论采用心脏四腔观联合心脏轴对胎儿进行检测,在一定程度上能够提高先天性心脏病检测的准确度。
Objective To investigate the value of echocardiography combined with four-chamber observation in the diagnosis of congenital heart disease. Methods From November 2014 to January 2016, 80 pregnant women with gestational age above 19 weeks who were examined by Shenyang Maternal and Child Hospital of Liaoning Province were enrolled in this study. The congenital Heart disease, followed by autopsy or follow-up of children to verify their production, analysis of its sensitivity and other indicators. Results The sensitivity of echocardiography combined with four-chamber examination in the diagnosis of fetal congenital heart disease was significantly higher than that of the simple four-chamber method (χ ~ 2 = 34.028, P = 0.000). Fetal heart of congenital heart disease The proportion of axial abnormalities was significantly higher than that of normal fetuses (P <0.05). The angle of mandibular axis was significantly higher in fetuses with congenital heart disease than in normal fetuses (P <0.05). Conclusion The detection of fetus by the combined four-chamber view of the heart and heart axis can improve the accuracy of detection of congenital heart disease to a certain extent.
