ABSTRACT
Introduction Structural congenital heart disease (CHD) is among the most common anomalies in prenatal ultrasound studies. Prenatal detection can significantly improve perinatal outcome at least in certain types of CHD.1-4 Various technical advances in ultrasound systems have promised improvements specifically for fetal echocardiography, but prenatal detection rates vary considerably and depend on factors like operator training and experience.5-8 Screening for fetal heart disease and detailed diagnosis of fetal heart disease require technologies of different complexities.9 This chapter attempts to review technical advances regarding fetal echocardiography.
