Abstract:

Cardiac anomaly is the most common developmental malformation and one of the leading causes of neonatal mortality and morbidity. As more women undergo prenatal diagnosis, the need for fetal echocardiography increases. Fetal echocardiography is a non-invasive method in detection of structural heart disease, cardiac arrhythmia and heart dysfunction. This paper not only discuses the indication, examination time, ultrasonic scanning plane, scanning technique, important advances and clinical application of fetal echocardiography, but also points out the limitation and prospects of research in this fields.

Key words: fetal echocardiography, heart function, arrhythmia, cardiac malformation
