目的 先天性心脏畸形是胎儿最常见的发育畸形,发生率高,预后差,妊娠期尽早发现胎儿心脏畸形,可降低畸形胎儿出生率,减少围产期胎儿死亡率,对优生优育、提高人口素质有重要意义.目前二维超声心动图是临床胎儿心脏检查常用且有效的手段,但由于胎儿心脏体积小、搏动快、结构复杂及二维超声平面信息量有限等因素的限制,很多复杂先心病在产前仍然无法检出.STIC是近几年发展起来的一项专用于胎儿心脏的动态三维超声成像技术,可以实时地显示心脏运动过程,使胎儿心脏空间结构的显示有了很大改善,目前正在被临床逐步推广.STIC的出现为胎儿心脏畸形的产前检出提供了新视角,本文就近年来STIC技术在胎儿心脏畸形中的应用研究展开综述.,Congenital heart malformation is a common development malformation for new b , which has high occurrence rate and bad prognosis .Earlier finding of heart malformation during gestation period can lower the birth rate of new b with such dis -ease and decrease the death rate of new b within perinatal period , which have significant importance for sound child rearing and improving population quality .Currently, the two-dimensional ultrasonic cardiogram is a common and effective way for hear chec-king of new b.However, because of small size, fast pulse, complex structure of new b’s heart, the limited graphic infor-mation of two-dimensional ultrasonic cardiogram and other limitations , there still are many complex heart disease that cannot be in-spected before b .STIC, a specialized newly-developed dynamic three-dimensional ultrasonic imaging technique , can display the movement process of heart at real time , which greatly improves the display for new b ’s heart, and is being promoted gradu-ally.The emerging of STIC provides new perspective for the antenatal inspection for heart malformation of new b .This thesis summarizes the recent application research on STIC technique of new b ’ s heart malformation .
