Those words — "there's something with the heart" — change everything
You're at your 20-week scan. Routine appointment. The sonographer studies the screen, pauses — and says: "I can see something in the heart, we need a closer look." Every parent who has heard these words knows: from that moment, the world shifts.
But here is the most important thing to hear first: these words are not a verdict. They are the beginning of the next step.
The majority of heart defects detected during pregnancy are successfully treated with modern medicine. What matters most is knowing what to do. Let's work through it together.
How does a pregnancy scan detect a heart defect?
The standard anatomy scan (20–22 weeks) shows the four chambers of the heart. The sonographer assesses their size, valve position, and the relationship of the major vessels.
Sometimes something catches attention — a chamber size, a valve position, a vessel direction. In that case, you're referred for a more detailed assessment.
Important to understand: a routine obstetric scan is not designed to fully evaluate the heart. Its job is to identify suspicious findings and refer you to a specialist. A suspicious result does not equal a confirmed defect.
Fetal echocardiography — the key investigation
When a screening scan raises a concern, the next step is a fetal echocardiogram (fetal echo).
This is a specialised ultrasound of the baby's heart — no radiation, completely safe for both mother and baby. It's usually performed between 22 and 28 weeks.
What does a fetal echo show? All the heart's structures: the four chambers, valves, great vessels, and direction of blood flow. This investigation either completely clears the concern — or precisely identifies the type and severity of the defect.
A fetal echo is performed by a paediatric cardiologist or perinatologist. The result should then be reviewed together with a paediatric cardiac surgeon.
If the fetal echo is normal
If the heart looks normal on the fetal echo, the suspicious finding on the screening scan was most likely due to technical factors: the baby's position, maternal body habitus, or image quality.
In that case, the pregnancy continues as normal. Sometimes a check echo after birth is recommended — this is a precautionary measure.
Take a breath — the investigation did its job.
If the fetal echo finds a defect — what happens next?
If the fetal echo confirms a congenital heart defect, that is difficult news. But at the same time, it is a significant advantage: you have time.
What does early diagnosis give you? The ability to plan the birth. Choice of delivery location — for serious defects, a perinatal centre with cardiac monitoring is recommended. Readiness for intervention immediately after birth. Time for the family to prepare emotionally.
The vast majority of families who receive this diagnosis prenatally go through the process in a planned, supported, and prepared way. That makes for significantly better outcomes than an unexpected situation in the delivery room.
Does the type of defect matter?
Not all congenital heart defects are the same. They can broadly be grouped into three categories:
Mild defects — small VSD, ASD, small PDA. Often monitored over time; some close on their own, others need minimal intervention. Children grow up completely healthy.
Moderate defects — require surgical intervention in infancy or early childhood. With modern techniques, outcomes are excellent — children return to a normal life.
Complex defects — tetralogy of Fallot, TGA, hypoplastic left heart syndrome, and others. These require a staged approach, but even here modern cardiac surgery achieves remarkable results.
The type of defect, its severity, and the treatment plan can only be precisely determined by a qualified paediatric cardiac surgeon.
What steps should parents take?
1. Stay calm, but don't stay still. Panic doesn't help — but neither does waiting. Plan your next step.
2. Get referred to a specialist centre for fetal echo. Not every clinic offers this — look for a centre with a perinatologist or paediatric cardiologist.
3. Review the fetal echo result with a paediatric cardiac surgeon. The cardiologist manages the medical side; the surgeon builds the surgical plan. You need both.
4. Don't hesitate to get a second opinion. For complex defects, a second qualified opinion is both your right and a sensible decision.
5. Avoid the worst-case internet rabbit hole. Every defect is individual, every child is individual. Statistics are not your child. Listen to your specialist.
Are these defects treated in Azerbaijan?
Yes. The vast majority of congenital heart defects are successfully operated on within Azerbaijan.
For complex defects — tetralogy of Fallot, TGA, large VSD — surgery is performed in infancy. Techniques meet international standards.
The desire to seek treatment abroad is understandable — but it is usually not necessary. The right approach is to first consult a local qualified specialist, then make an informed decision.
If you have doubts — come in for a consultation. We'll assess the situation together and find the best path forward.
The bottom line: a diagnosis is not the end — it's the beginning
A heart defect diagnosis during pregnancy feels catastrophic. But in truth, it is a timely gift.
Because of early diagnosis, the family is prepared, the medical team is prepared, and the birth is planned. That is an incomparably better start than an unexpected crisis in the delivery room.
If you have questions — reach out. You are not alone on this road.
