【摘要】 目的 探讨胎儿超声心动图在产前诊断胎儿先天性心脏病的临床价值。方法选择妊娠>20周,有高危倾向的孕妇及会诊病例共315例行胎儿超声心动图检查。采用胎儿四腔心切面、左右室流出道切面、左室长轴及主动脉根部短轴切面、主动脉弓切面、动脉导管弓切面、三血管切面及上下腔静脉长轴切面、双房及双室短轴切面，观察心脏大小、结构、大血管的位置、走行等；应用彩色多普勒血流显像观察各瓣口及间隔、大血管内血流情况。结果 共发现32例先天性心脏病胎儿,其中单心室2例；单心房1例；右心双出口1例，完全性心内膜垫缺损8例，左心发育不良2例；三尖瓣闭锁2例；法洛四联症4例；主动脉瓣狭窄1例；肺动脉瓣狭窄3例；单纯室间隔缺损8例。漏诊房间隔继发孔缺损2例；漏诊肺动脉狭窄1例；敏感性91 %,特异性1 0 0 %。结论 胎儿超声心动图是产前诊断胎儿先天性心脏病的最主要的无创性诊断技术，对围产期临床正确处理有重要的指导作用。

    【Abstract】Objective to investigate the effects of fetal echocardiography in the clinical value of prenatal diagnosis of fetal congenital heart disease. Methods choose pregnancy > 20 weeks, has a tendency to high-risk pregnant women and 315 consultation cases of routine fetal echocardiography. Using fetal four-chamber view, left and right ventricular outflow tract, left for the final axis and short axis section of the aortic root, aortic arch section, arterial catheter bow section, three vessels on the plane and inferior vena cava long axis section room, double room and two short shaft section, observe the position of the heart size, structure, great vessels, go, etc.; Application of color doppler flow imaging to observe the valve opening and interval, big endovascular blood flow. ......
