Fetal Echocardiography in Ahmedabad: A Closer Look at Your Baby's Heart

A fetal echo is a detailed ultrasound of the unborn baby's heart. It checks the chambers, valves, main vessels, blood flow and rhythm, usually at 18–24 weeks of pregnancy. It is advised when there is a higher chance of a heart condition. Dr. Devang Patel performs this heart scan at Divine Women's Hospital, Gota, as part of his fetal medicine work.

How common are heart conditions?
About 8 in every 1,000 births.

Congenital heart conditions are the most common structural difference found in babies, affecting about 8 in 1,000 births. Many are minor and either close by themselves or need no treatment. Around a quarter, however, are critical and need care within the first weeks of life. When a significant condition is found before birth, the delivery can be planned at a place where paediatric cardiology and neonatal support are available.

The fetal echo goes further than the heart views included in the routine anomaly scan. I check every chamber, valve and major vessel in turn, use colour Doppler to see how the blood flows, and study the rhythm. I usually do it at 18–24 weeks; in selected high-risk pregnancies an early scan is possible from 13–16 weeks.

I read the heart findings together with the rest of the baby's anatomy, any genetic results and your medical history, and give you one combined plan.

Why I Sometimes Add a Fetal Echo Scan

The baby's heart forms roughly between 3 and 8 weeks after conception. At that stage, high blood sugar, some medicines, inherited factors and chromosomal conditions can all raise the chance of a heart defect.

Even so, about 9 in 10 babies with a heart defect are born to parents who had no known risk factor. That is why every anomaly scan includes views of the heart. I add a fetal echo when the risk is higher, or when the routine views raise a question. It is a targeted test, not something every pregnancy needs.

Fetal Echo Test in Pregnancy: Who I Advise to Have It

  • Diabetes that started before pregnancy, or an HbA1c above about 6.5% in early pregnancy.
  • Pregnancy through IVF or ICSI.
  • A parent or a previous child with a congenital heart condition (a chance of roughly 2–5%).
  • An NT of 3.5 mm or more, or abnormal ductus venosus or tricuspid flow at the NT scan.
  • Heart views at the anomaly scan that could not be confirmed as normal.
  • Monochorionic twins, especially with twin-to-twin transfusion syndrome.
  • Anti-Ro or anti-La antibodies (linked with lupus or Sjögren's syndrome), because of the risk of heart block.
  • Certain medicines in early pregnancy: valproate, lithium, isotretinoin or high-dose retinoids.
  • A fast, slow or irregular heartbeat in the baby, hydrops, or another structural or chromosomal finding.
  • Parents who are blood relatives (consanguinity).

Fetal Echocardiography Time: When in Pregnancy It Is Done

The usual time for fetal echocardiography is 18–24 weeks. By then the heart is large enough to show each valve and vessel clearly, and the bones are not yet dense enough to cast heavy shadows across the chest.

Some pregnancies need an early heart scan at 13–16 weeks. Examples are a previous baby with a heart condition, an NT of 3.5 mm or more, or a worrying view at the NT scan. It can pick up some major conditions sooner, but the heart is still tiny, so it is always followed by a full echo later rather than replacing it.

After a heart condition has been found, follow-up echoes are often planned at 28–32 weeks and again before delivery. They show how the heart is developing and help fine-tune the birth plan. Set aside 30–60 minutes for each visit. If you already have an anomaly scan booked, tell the hospital when you call. The two can often be planned close together, so that the heart findings are read alongside the rest of the anatomy.

Fetal Echo in Pregnancy: The Procedure and What I Examine

The procedure itself is like any abdominal ultrasound. You lie back, slightly turned to one side if that is more comfortable; gel is applied, and I move the probe over your bump. Nothing is inserted and no injection is needed. I then work through the heart in a set order:

  • Where the heart sits in the chest.
  • The four chambers and the walls that divide them.
  • The mitral and tricuspid valves.
  • The aorta and the pulmonary artery as they leave the heart and cross over each other.
  • The three-vessel and trachea view, the arch views, and the veins bringing blood back to the heart.
  • Colour and pulsed Doppler, to check the direction and speed of flow through the valves.
  • M-mode and Doppler recordings to study the rhythm.
  • In pregnancies with anti-Ro antibodies, the PR interval - the timing between the upper and lower chambers.

Heart Conditions I Look For and What They Mean

ConditionWhat it isWhat it usually means for the baby
Ventricular septal defect (VSD)A hole between the two lower chambersSmall ones often close; larger ones may need surgery in infancy
Atrioventricular septal defect (AVSD)A central hole with one shared valveSurgery in infancy; because of the link with Down syndrome, I discuss genetic testing
Tetralogy of FallotA VSD together with narrowing of the pulmonary outflowSurgical repair, usually within the first year
Transposition of the great arteriesThe aorta and pulmonary artery are switchedBirth at a cardiac centre and early surgery
Coarctation of the aortaNarrowing of the aortic archSuspected before birth, confirmed afterwards; may need surgery
Hypoplastic left heartThe left side of the heart is underdevelopedComplex surgery in stages; I counsel you in detail on every option

Fetal Heart Rhythm Problems

Irregular beats are common in the womb. Usually they are harmless extra beats that settle on their own; I confirm the rhythm on the echo and then follow the heart rate until it settles.

A fast rhythm that keeps going (supraventricular tachycardia) can strain the baby's heart. It can be treated with a medicine given to the mother, which crosses the placenta to the baby. Complete heart block, usually linked with anti-Ro antibodies, is monitored closely, and the delivery is planned with support from paediatric cardiology.

When the Fetal Echo Shows a Heart Condition

I will tell you what the condition is, how it affects the circulation before and after birth, and how sure I am of the diagnosis.

  • Some heart conditions are linked to chromosomal differences, such as Down syndrome or a 22q11 deletion, so I usually suggest amniocentesis with microarray.
  • Follow-up echoes track how the heart develops, often at 28–32 weeks and again before delivery.
  • If the baby will need care soon after birth, I plan the delivery at a hospital with a paediatric cardiac surgery team.
  • For minor conditions, the usual plan is reassurance and an echo for the baby after birth.
  • Most babies with a heart condition can be born vaginally; the heart condition by itself is rarely a reason for a caesarean.
  • With a complex or severe condition, I go through every option, the number of operations the baby may need and the long-term outlook. This way your decisions are informed and not rushed.

Knowing about a critical heart condition before birth gives time to plan where and how the baby will be born.

Fetal Echocardiography Report: What It Contains

Your fetal echocardiography report follows the same order as the scan, so you can match each line to what we discussed.

  • Position and rhythm - where the heart sits, the heart rate and whether the rhythm is regular.
  • Chambers and valves - the four chambers, the dividing walls, and the mitral and tricuspid valves.
  • Great arteries and veins - the aorta and pulmonary artery, the three-vessel and trachea view, the arches, and the veins returning blood to the heart.
  • Doppler - the direction and speed of flow across the valves.
  • Conclusion - either "normal heart anatomy within the limits of this scan", or a named condition with how certain the diagnosis is.
  • Recommendations - a follow-up echo, genetic testing, a paediatric cardiology opinion, or an echo for the baby after birth.

The phrase "within the limits of this scan" is deliberate. It reminds every doctor who reads the report later that some conditions cannot be judged before birth, as the next section explains.

What a Fetal Echo Cannot Show

  • Some heart conditions cannot be seen before birth.
  • Very small VSDs may not be visible.
  • The foramen ovale and the ductus arteriosus are normal openings in every unborn baby, so problems with them (ASD, PDA) can be judged only after birth.
  • Coarctation can be suspected, but sometimes it is confirmed only after delivery.
  • Image quality depends on the baby's position, your body build and the amount of amniotic fluid, so a repeat scan is sometimes needed to complete the views.

Fetal Echo in the Next Pregnancy, and How I Coordinate Care

After one baby with a congenital heart condition, the chance in the next baby is roughly 2–3%. It is higher if more than one family member is affected or if a genetic cause is found. In the next pregnancy I usually advise folic acid before conception, good diabetes control, an early heart scan at 13–16 weeks and a full fetal echo at 18–22 weeks.

At Divine Women's Hospital, Gota, I perform the echo myself as part of fetal medicine care and link the findings with the NT scan, anomaly scan and genetic results. If a significant condition is confirmed, I refer you to a paediatric cardiologist and, when needed, to a cardiac surgical centre in Ahmedabad. We then write the birth plan down together in Gujarati, Hindi or English. If the baby will not need special care, the delivery can take place at Divine Women's Hospital. The hospital has staff available 24×7 for labour and emergencies, and neonatal support. The baby's heart is checked again after birth.

Fetal Echocardiography Test Price: What Decides the Charge

I do not quote a figure here; current charges come from the hospital, on request, at the time of booking. What the charge depends on:

  • Number of babies - in twins each heart is examined separately, which takes much longer.
  • One visit or a series - an early heart scan at 13–16 weeks followed by a full echo, or follow-up echoes after a diagnosis, are separate visits.
  • Combined with other scans - whether the echo is done alongside an anomaly or growth scan, or on its own.
  • Further steps - genetic testing such as amniocentesis with microarray, and a paediatric cardiology consultation, are separate from the echo.

When you call, mention the reason for the echo (for example diabetes, IVF or a finding on another scan) and whether it is a twin pregnancy. The information you are given will then fit what is actually planned.

Your Fetal Echo Visit, Step by Step

  1. Looking at the referralbeforehand, I go through the reason for the echo, your earlier scan reports, your sugar control and your medicines.
  2. The heart scanI assess the structure, the flow and the rhythm in a set order; this usually takes 30–60 minutes.
  3. Talking it throughI explain what I have found using diagrams, including what it would mean after birth.
  4. Genetic and specialist inputwhere needed, I arrange genetic testing and a paediatric cardiology consultation.
  5. Follow-up and birth planrepeat echoes, the place of delivery and the newborn heart check are planned ahead of time.

Signs You Should Book a Fetal Echo

  • You have diabetes from before pregnancy, or conceived through IVF or ICSI.
  • You, your husband or a previous child has a congenital heart condition.
  • Your NT measured 3.5 mm or more.
  • The anomaly scan could not confirm that the heart views were normal.
  • You have anti-Ro or anti-La antibodies, or the baby's heartbeat has been irregular.
  • You took valproate or lithium in early pregnancy.

When Not to Wait for Your Fetal Echo Appointment

Come in the same day if you notice any of these:

  • A clear drop in, or change to, the baby's movements after 24 weeks.
  • A bump that is growing quickly, with breathlessness (this can mean too much fluid).
  • Vaginal bleeding or leaking fluid.
  • Pain high in the abdomen, a bad headache or blurred vision.
  • Fever above 38 °C, or feeling very unwell.

Any of these is a reason to go to Divine Women's Hospital the same day; hospital staff are there 24×7, and a phone call on the way helps them prepare.

Fetal Heart Myths, Answered

Belief: If the anomaly scan was normal, the heart must be normal.

The routine heart views pick up many serious defects, but not all. When the risk is higher, a fetal echo looks in much more detail.

Belief: A heart defect means the baby will not survive.

Most congenital heart conditions can be treated, and many children lead normal lives after surgery or without needing any treatment.

Belief: A baby with a heart condition has to be delivered by caesarean.

Most can be born vaginally. The planning is mainly about where the baby is born.

Belief: Lifting weights or stress causes heart defects.

Most heart defects have no identifiable cause and are not linked to work, travel, stress or diet. Uncontrolled diabetes is the exception.

Questions Patients Often Ask Me About Fetal Echo

At what stage of pregnancy is fetal echocardiography done?

Usually at 18–24 weeks. In high-risk pregnancies I may do an early scan from about 13–16 weeks, followed by a full echo later.

Is a fetal echo the same as the heart check in the anomaly scan?

No. The anomaly scan includes the standard heart views as part of a check of the whole body. A fetal echo is a longer examination dedicated to the heart, with more views and detailed Doppler.

Will a fetal echo show a hole in the baby's heart?

Larger holes, such as many VSDs and AVSDs, can usually be seen. Very small holes may not be visible, and an ASD cannot be judged before birth.

Can a fetal echo harm my baby?

Diagnostic ultrasound used within standard safety settings has no proven harmful effect on the baby. The fetal echo is done through the abdomen, with no radiation and no needle.

Why do I need a fetal echo after IVF?

Babies conceived by IVF or ICSI have a slightly higher chance of a heart defect - about 1–1.5%, compared with under 1% in the general population.

I have diabetes. Will good sugar control lower the risk?

Yes. The risk rises with the HbA1c in early pregnancy, and good control before conception and through the first trimester lowers it. I still advise a fetal echo.

What if my baby's heartbeat is irregular?

Most irregular beats are harmless extra beats that settle. The echo identifies the type of rhythm, and the few babies who need treatment are monitored with paediatric cardiology support.

Will my baby need heart tests after birth?

If a condition was suspected before birth, the baby has an echo after delivery. Routine newborn checks, including pulse oximetry, can also help detect some conditions.

Can a heart problem seen on the scan disappear?

Some can - small muscular VSDs, for example, and mild valve leaks or a chamber that looked prominent may settle on later scans. Structural conditions such as transposition do not go away.

How do I prepare for a fetal echo?

You do not need to fast or have a full bladder. Bring your NT and anomaly scan reports, your latest HbA1c if you have diabetes, and a list of your medicines. Wear loose clothing and allow up to an hour.
