      【摘要】 目的 探讨超声在产前胎儿心脏畸形筛查中的准确率及影响因素。方法 回顾性分析在我院进
行了胎儿心脏超声筛查的孕妇1 200例。运用四腔心切面、左心室流出道、右心室流出道及三血管气管切面对心
脏进行系统筛查。结果 产后经证实的新生儿心脏畸形有26例，产前超声诊断为心脏畸形胎儿25例，准确率为
96.15% (25/26)；产前用四腔心切面加声束法检查胎儿心脏3个基本切面(四腔心切面及左、右室流出道切面)，其
显示率在孕22~30周达98%，孕31~42周和孕18~21周分别为88.67%和79.33%。结论 产前超声筛查胎儿先天
性心脏畸形要注意选择合理切面及在孕妇合适的孕周进行检查以提高准确率。

【Abstract】 Objective To explore the accuracy and influencing factors of ultrasonography in the prenatal
screening for fetal cardiac malformations. Methods The clinical data of 1 200 pregnant women undergoing fetal
cardiac ultrasound screening in our hospital were retrospectively analyzed. Four chamber views, left ventricular
outflow tract, right ventricular outflow tract, and three vessels trachea view were used to screen the heart systemat-
ically. Results 25 cases were diagnosed as cardiac malformations prenatally, and 26 cases were conformed as cardi-
ac malformations after delivery, with the diagnosis accuracy of 96.15% (25/26). Four chamber view prenatal plus
beam method for detecting fetal heart 3 basic section(four chamber views, left and right ventricular outflow tract view.
The display rate at 22~30 weeks gestation was up to 98%, at 31~42 weeks and 18~21 weeks gestation were 88.67%
and 79.33%, respectively. Conclusion In prenatal ultrasound screening for fetal cardiac malformations, we should
pay attention to choose the right section in pregnant women, appropriate gestational age in order to improve accuracy.
