Fetal echocardiogram (baby heart scan)
Quick answer: A fetal echocardiogram is a detailed ultrasound of the unborn baby's heart that looks at its chambers, valves, vessels and rhythm. It is usually done around 18 to 24 weeks when there is a higher chance of a heart problem, such as a family history, diabetes, IVF pregnancy or a finding on another scan.
- SampleImaging (no sample)
- TakesAbout 30 minutes to an hour
- Before the testNo special preparation is usually needed.
- In fertility careSome doctors recommend a fetal echo in IVF and ICSI pregnancies, as some studies show a slightly higher rate of heart defects.

What your results can mean
Reading your report
Measurements are compared with what is expected for the stage of pregnancy; your doctor will explain what your report means for you and your baby.
If the result is outside the usual range
A fetal echo can show differences in how the baby's heart chambers, valves or major vessels have formed, or an unusual heart rhythm. Some small heart problems cannot be seen before birth, and a normal scan lowers but does not remove the chance of a heart condition.
Who usually has this test
Pregnant women with a family history of heart defects, diabetes, an IVF pregnancy, certain medicines, or a heart concern seen on another scan.
Risks and aftercare
It uses sound waves, not radiation, and is considered safe for you and the baby; pressure on a full belly may feel uncomfortable, and there is no aftercare.

Questions about this test
When is a fetal echo done?
It is usually done around 18 to 24 weeks of pregnancy, when the baby's heart is large enough to see in detail. Sometimes it is repeated later.
Is a fetal echo needed after IVF?
Some doctors recommend it in IVF and ICSI pregnancies because some studies show a slightly higher rate of heart defects. Your doctor will advise based on your situation.
How is a fetal echo different from an anomaly scan?
The anomaly scan checks the whole baby, including a basic heart check. A fetal echo spends much longer on the heart alone, looking at its structure and rhythm in more detail.
