A Primer for Fetal Cardiac Imaging 

A Stepwise Approach for 2-Dimensional Imaging 

(Ultrasound Quarterly 2008;24:195Y206) 

American Institute of Ultrasound in Medicine (AIUM) and the Intern

ational Society of Ultrasound in Obstetrics and Gynecology outlined 

recent guidelines for sonographic evaluation of the fetal heart. The 

International Society of Ultrasound in Obstetrics and Gynecology gui

delines include the “basic”cardiac examination that relies on a 4-cha

mber view.There are key features of this sonographic view that will

 be emphasized in this article. This society also included the “exten

ded basic” examination that includes the right and left ventricular o

ut-flow tracts (RVOTand LVOT, respectively). It is important to inclu

de imaging that demonstrates the relationship of the LVOT and the

 RVOT to detect conotruncal abnormalities. 

美国超声医学协会(

AIUM)和国际妇产科超声协会最近针对胎儿心脏超声

检查出台了一项指南。国际妇产科超声协会指南包括了基于四腔心切面的

最基本的心脏检查,其中重点强调了在此超声切面上的几个关键征象,同

时指南还包括了

“进一步”的检查,包括对左右心室流出道(RVOT 和 LVOT)

的检查,明确两者的关系对于发现圆锥动脉干畸形非常重要。
