First Trimester Fetal Echocardiography

Abstract

First trimester fetal echocardiography was introduced two decades ago. This service is usually available in specialist fetal medicine units but it is not included in routine prenatal screening programs. Early fetal heart assessment is important as it can provide early reassurance or diagnosis of a cardiac abnormality which may potentially instigate further investigation. First trimester fetal echocardiography also provides an insight into the early features and progression of certain forms of congenital heart disease (CHD). In this chapter, the technique of early fetal echocardiography, and first trimester sonographic markers for possible CHD are presented.
