How many weeks is it appropriate to check the heart during pregnancy?

Pregnancy examination of heart color ultrasound is generally appropriate between 24 weeks and 29 weeks.

During pregnancy, heart color ultrasound examination is a very important screening method, which can understand whether the fetal heart structure and function are normal, and whether there are abnormalities such as congenital heart disease. At 24 - 29 weeks of pregnancy, because the fetus 'heart has developed perfectly, the four chambers, valves, lumens, arteries and other structures of the heart can be clearly observed through cardiac color Doppler ultrasound, and whether the fetus has cardiac malformation or other abnormal conditions, such as pericardial effusion, cardiac tumor, etc., can be checked. Therefore, it is generally appropriate to check cardiac color Doppler ultrasound during pregnancy between 24 - 29 weeks.
