Patient's question:
I had a congenital heart defect with my first child. I am now three months pregnant, and this is my second child. When can I have an echocardiogram during pregnancy?Doctor's answer:
The best time to do a four-dimensional ultrasound is between the 5th and 8th months of pregnancy (20-28 weeks), as this period is when the fetus's limbs and major organs have fully developed, and the amniotic fluid is most suitable for fetal anomaly screening. However, due to individual differences among pregnant women, please contact your doctor to determine the specific timing according to medical advice.
