Abstract： 目的探讨超声心动图的四腔心切面(四腔心切面)产前诊断胎儿先天性心脏病(先心病)的价值.方法回顾性分析780例妊娠16～36周通过四腔心切面进行产前诊断的孕妇及其新生儿的临床资料.结果 780例胎儿中,94.6%(738/780)的胎儿可以获取满意的四腔心切面,其中3例胎儿异常,1例为三尖瓣下移畸形(Ebstein 综合征),1例为严重的室间隔缺损,1例为单心房单心室和主动脉狭窄.例1和例3分别于出生后行尸体解剖和新生儿超声心动图检查,均符合产前诊断,例2出生后超声心动图检查证实为单心房和单心室.其余777例新生儿中,出生后身体检查并追踪至产后6周,发现3例先心病,其中1例室间隔缺损,1例房间隔缺损,1例房间隔缺损伴肺动脉狭窄.四腔心切面诊断胎儿先心病的敏感性为50%,特异性为100%.结论四腔心切面可以显示胎儿心脏的大部分结构,探测成功率高,对先心病的宫内诊断有较高的敏感性和极高的特异性,可将胎儿四腔心切面作为常规的产前超声检查项目.
