摘要
目的评价胎儿心脏自动容积导航技术(smart-planes fetal heart,S-planes FH)获得胎儿心室流出道切面的可行性,同时比较S-planes FH和二维超声心动图(2DE)测量胎儿主动脉(AO)与肺动脉(PA)内径的一致性。方法选取185例中晚孕期胎儿作为研究对象。进行2DE检查,测量胎儿AO与PA内径。再应用三维容积探头通过表面模式获取胎儿心脏容积数据并存储,利用S-planes FH软件对数据进行脱机分析,对显示清晰的AO、PA进行测量。采用线性Pearson相关分析法评价两种方法测得AO、PA的相关性。应用Bland-Altman分析验证两种方法的一致性。结果185例胎儿经2DE检查均能获得满意的胎儿心室流出道切面,其中173例(93.5%)应用S-planes FH成功获取了胎儿心室流出道切面。经线性Pearson相关分析显示,两种方法测量AO、PA内径值有很好的相关性(r=0.84,P=0.04;r=0.81,P=0.00)。Bland-Altman分析显示两种方法有较好的一致性,95%一致性界限分别为(-1.17,1.00)、(-1.79,1.02)。结论应用S-planes FH和常规2DE测量胎儿AO、PA内径值具有良好的一致性,S-planes FH获得流出道切面具有较高的可靠性及重复性。
Objective To explore the feasibility of smart-planes fetal heart (S-planes FH) in the display of the fetal ventricular outflow views, and to compare diameters of fetal aorta (AO) and pulmonary artery (PA) measured using two-dimensional echocardiography(2DE) and S-planes FH. Methods One hundred and eighty-five fetuses with gestational age of 17-36 weeks were enrolled. Each fetus had undergone conventional 2DE examination and the three-dimensional fetal cardiac volume datasets were obtained. The volume datasets were analyzed offline using S-planes FH. The diameters of AO and PA were measured by 2DE and S-planes FH, respectively. Pearson correlation analysis was used to evaluate the correlation between the two methods for measuring the diameters of AO and PA. The consistency of the two methods was verified by Bland-Altman analysis. Results Fetal ventricular outflow views were successfully obtained using S-planes FH in 173(93.5%) cases of 185 fetuses whose ventricular outflow views were satisfactorily obtained by fetal 2DE. There were close correlations between the two methods in measuring the diameters of AO and PA (r=0.84, P=0.04;r=0.81, P=0.00). Bland-Altman analysis showed a close consistency between the two methods, and their 95%confidence intervals were (-1.17, 1.00) and (-1.79, 1.02), respectively. Conclusions There is a close consistency between S-planes FH and 2DE in measuring fetal AO and PA. S-planes FH may have potential for the evaluation of fetal ventricular outflow.
