Abstract:

Congenital heart disease (CHD) is among the most frequent anomalies at birth and the main cause for fetal and infant death. Fetal echocardiography is the most frequently used and reliable technique in prenatal diagnosis of CHD and is developing rapidly both in China and abroad. This paper reviews the detection rate and associated influencing factors for fetal echocardiography in order to understand the prenatal diagnosis value of fetal echocardiography and provide reference for diagnosis with fetal echocardiography.

Key words: fetal echocardiography, congenital heart disease, prenatal diagnosis
