Can prenatal examinations detect congenital heart disease?

Patient's question:

Recently, I don't know why I've been feeling uncomfortable with my heart. Although I often take medication to control it, the effect is not obvious. When I went to the hospital for a check-up, they also prescribed medication. Can prenatal examinations detect congenital heart disease?

Doctor's answer:

Prenatal examinations mainly involve a series of detailed checks for pregnant women, the fetus, and the child. If the child has a heart disease, it can also be detected through these examinations, especially around the 18th to 20th week of pregnancy. At this time, it is recommended to go to the hospital for a four-dimensional color Doppler ultrasound to perform major anomaly screening, which can clearly observe the condition of the child's heart. If the father has congenital heart disease, this condition has a certain genetic predisposition.
