| 目的 分析胎心容积辅助诊断工具对孕中晚期单胎胎儿心脏流出道病变筛查的可行性。方法 选择2019年7月～10月在我院行超声检查的孕中晚期单胎孕妇190例,所有胎儿除了行常规二维超声心动图检查外,还对其胎儿心脏容积数据进行采集、储存；然后使用胎心容积辅助诊断工具对成像进行后处理；分析两种方法测量获得的主动脉和肺动脉内径之间的相关性,两种方法的一致性,以及观察者内和观察者间的重复性。结果 176例(92.63%)孕妇采用胎心容积辅助诊断工具获得了胎儿心脏左、右室流出道切面的清晰图像,能够测量主动脉和肺动脉内径；Pearson相关性分析结果提示,两种不同超声检查方法测得的主动脉和肺动脉内径值呈正相关(P均＜0.05)；Bland-Altman 图检验结果提示,两种不同超声检查方法测得主动脉、肺动脉内径的一致性较好,95%一致性界限分别在(-1.18～1.01)、(-1.81～1.03)；此外,胎心容积辅助诊断工具测量主动脉内径、肺动脉内径观察者间及观察者内的ICC值均＞0.85。结论 胎心容积辅助诊断工具在孕中晚期单胎胎儿心脏流出道病变筛查中具有较好的应用价值。 |

| Abstract: |
| Objective To analyze the feasibility of assisted diagnosis of fetal heart volume in the screening of cardiac outflow tract lesions in single fetuses during middle and late pregnancy. Methods 190 cases of single pregnant women in mid-late pregnancy who underwent ultrasound examination in our hospital from July to October 2019,All fetuses except routine 2D echocardiography,Collect and store fetal heart volume data；Then use the fetal heart volume assistant diagnostic tool to post-process the imaging；Consistency of the two methods and repeatability within and between observers. Results 176 (92.63%) pregnant women obtained a clear image of the left and right ventricular outflow tract sections of the fetal heart using the fetal heart volume assisted diagnosis tool,Capable of measuring aortic and pulmonary inner diameters；Pearson linear correlation analysis results suggest that,The aortic and pulmonary artery diameters measured by two different ultrasound examination methods were positively correlated (both P <0.05)；Bland-Altman plot test results suggest that,The consistency of the inner diameters of the aorta and pulmonary artery measured by two different ultrasound examination methods is good,The 95% consistency limits were (-1.18 to 1.01) and (-1.81 to 1.03), respectively；In addition, fetal heart volume assisted diagnostic tools measured ICC values of aortic diameter, pulmonary artery inner diameter among observers, and within observers were all> 0.85.Conclusions The fetal heart volume assisted diagnostic tool has a good application value in the screening of cardiac outflow tract lesions in single fetuses during the second and third trimesters. |
