A fetal echo is a detailed ultrasound of the baby's heart, usually done between 18 and 24 weeks. Learn who needs it and what to expect.
The routine anomaly scan looks at the whole baby, including a basic view of the heart. A fetal echo goes much further. It studies the heart chambers, valves, major vessels, blood flow and heart rhythm in detail.
The best window is usually 18 to 24 weeks, when the heart is large enough to be seen clearly. In some high-risk situations an early fetal echo may be done at about 12 to 16 weeks, and it can be repeated later if needed.
The test is like a regular ultrasound. Gel is applied to the abdomen and a probe is moved over it. It is painless and safe for mother and baby. It can take 30 to 60 minutes, as the baby's position matters.
A normal result is reassuring. If a heart problem is found, your doctor will explain what it is, how it may affect the baby, where delivery should be planned and what treatment is likely after birth. Knowing early allows better planning.
Most babies have a healthy heart, but a fetal echo gives answers when there is a reason to look closer. Dr Malathi G. Prasad at Trichy Fetal Medicine and Fertility Centre in Trichy can advise whether you need one and explain the findings clearly.
If this applies to your pregnancy, our fetal echo page explains what the visit involves, or you can meet our specialists before you decide anything.
