Congenital Heart Disease in Children: Types, Symptoms, Diagnosis, Treatment and Cost in India

Congenital heart disease (CHD) is a problem with the structure of the heart that is present at birth. It is the most common type of birth defect, affecting roughly 8 to 10 out of every 1,000 babies born worldwide. Some defects are minor and close on their own, while others need treatment in the first days, months or years of life. In many parts of Africa, the Middle East, Central Asia and South Asia, access to specialised paediatric cardiac surgery is limited, and many children are diagnosed late. The encouraging news is that with timely treatment, the great majority of children with CHD grow up to lead normal, healthy lives. India has some of the busiest paediatric cardiac centres in the world, treating children from many countries at an affordable cost.

What is Congenital Heart Disease?

The heart develops during the first eight weeks of pregnancy. If something goes wrong during this process, a baby may be born with a hole between the heart chambers, an abnormal valve, a narrowed blood vessel, or blood vessels connected in the wrong places. CHD is usually divided into two broad groups:

Acyanotic (non-blue) heart defects

• Ventricular septal defect (VSD) - a hole between the two lower chambers; the most common defect.
• Atrial septal defect (ASD) - a hole between the two upper chambers.
• Patent ductus arteriosus (PDA) - a blood vessel that should close after birth remains open.
• Atrioventricular septal defect (AVSD) - a larger defect in the centre of the heart, common in children with Down syndrome.
• Pulmonary stenosis, aortic stenosis and coarctation of the aorta - narrowing of a valve or of the main artery.

Cyanotic (blue) heart defects

• Tetralogy of Fallot (TOF) - the most common cyanotic defect, combining a VSD, narrowing of the pulmonary outflow, an overriding aorta and a thickened right ventricle.
• Transposition of the great arteries (TGA) - the main arteries are switched, and urgent surgery is needed in the first weeks of life.
• Total anomalous pulmonary venous connection (TAPVC), truncus arteriosus, tricuspid atresia and single ventricle defects such as hypoplastic left heart syndrome.

Cyanotic defects reduce the amount of oxygen in the blood, giving the lips, tongue and nails a bluish colour - often called "blue baby" syndrome.

Causes and Risk Factors

In most children no single cause is found. Known risk factors include:

• Genetic conditions such as Down syndrome, DiGeorge (22q11 deletion) syndrome, Turner syndrome and Noonan syndrome.
• Family history of congenital heart disease in a parent or sibling.
• Marriage between close relatives (consanguinity), which is common in parts of the Middle East, North Africa and South Asia and is associated with a higher risk of some birth defects.
• Maternal infections in pregnancy, especially rubella (German measles) in areas with low vaccination coverage.
• Maternal diabetes, obesity and phenylketonuria that are poorly controlled.
• Certain medicines, alcohol and smoking during pregnancy.
• Older maternal age, which increases the chance of chromosomal conditions.

Symptoms of Congenital Heart Disease

Symptoms depend on the type and size of the defect. Some babies are unwell from birth, while others are diagnosed years later when a doctor hears a murmur. Common signs include:

• Fast breathing or breathlessness, especially during feeding
• Sweating while feeding and tiring quickly
• Poor weight gain and slow growth
• Bluish lips, tongue or nails (cyanosis)
• Frequent chest infections
• Tiring easily during play compared with other children; in TOF, older children may squat to rest
• A heart murmur heard by a doctor
• Swelling around the eyes or legs in some cases

Seek emergency care if your child has: sudden worsening of blue colour with fast breathing, irritability or fainting ("cyanotic spells" in TOF), severe breathing difficulty, refusing feeds with lethargy, or cold, pale and clammy skin.

How is Congenital Heart Disease Diagnosed?

• Fetal echocardiography - many defects can be detected during pregnancy, usually around 18 to 22 weeks.
• Pulse oximetry screening - a simple test after birth to detect low oxygen levels.
• Echocardiography (ECHO) - the main test that shows the heart's structure and blood flow.
• ECG and chest X-ray.
• CT angiography or cardiac MRI - for detailed images of complex defects and blood vessels.
• Cardiac catheterisation - to measure pressures, and often to treat the defect at the same time.
• Genetic testing when a syndrome is suspected.

Treatment Options for Congenital Heart Disease

1. Observation

Small VSDs, small ASDs and mild valve narrowing may close on their own or never need treatment. The child is followed up with regular echocardiograms.

2. Medicines

Diuretics and other medicines help children with heart failure symptoms feed and grow until the right time for repair. In newborns with certain critical defects, a medicine called prostaglandin keeps the ductus arteriosus open until surgery.

3. Interventional (non-surgical) procedures

Many defects can now be treated through a thin tube (catheter) inserted through a blood vessel in the groin, without opening the chest:

• Device closure of ASD, PDA and selected VSDs using special umbrella-like devices.
• Balloon valvuloplasty for pulmonary or aortic valve stenosis.
• Balloon angioplasty and stenting for coarctation of the aorta and narrowed vessels.

Recovery is quick, often with discharge within 1 to 2 days.

4. Open heart surgery

Larger or complex defects need surgery using a heart-lung machine. Common operations include VSD and AVSD closure, total correction of Tetralogy of Fallot, the arterial switch operation for TGA, TAPVC repair and staged operations (Glenn and Fontan) for single ventricle hearts. Some babies need a temporary procedure, such as a BT shunt, before complete repair.

5. Lifelong follow-up

Children who have had complex repairs need regular check-ups into adulthood, and some will need further procedures, such as pulmonary valve replacement, years later.

Recovery and Life After Treatment

After device closure, most children return to normal activities within a week. After open heart surgery, children usually spend a few days in the paediatric cardiac ICU and about 7 to 14 days in hospital in total. Most return to school in 4 to 6 weeks, and many grow up to play sports, work and have families of their own.

• Attend all follow-up appointments and echocardiograms.
• Ensure good nutrition to help the child catch up on growth.
• Keep up with routine childhood vaccinations.
• Maintain excellent dental hygiene; some children need antibiotics before dental procedures to prevent endocarditis.
• Follow your cardiologist's advice on physical activity.

Some cases can be prevented or reduced by rubella vaccination before pregnancy, good diabetes control, folic acid supplements, avoiding alcohol and smoking, and genetic counselling for families at higher risk. Fetal echocardiography helps parents plan delivery at a centre with paediatric cardiac care.

Frequently Asked Questions

Can a hole in the heart close on its own?

Yes, many small VSDs and ASDs close naturally in the first few years of life. Larger holes, or those causing symptoms or poor growth, usually need device closure or surgery.

What is the best age for heart surgery in children?

It depends on the defect. Some, like TGA, need surgery within weeks of birth, while TOF is often repaired in the first year of life and ASDs are often closed in early childhood. Your paediatric cardiologist will advise on the ideal timing.

Is device closure better than surgery?

When the defect is suitable, device closure avoids opening the chest and allows faster recovery. However, not all defects can be closed with a device, and surgery remains the best option for many.

How long will we stay in India for my child's heart treatment?

Usually about 7 to 10 days for device closure and about 3 to 4 weeks for open heart surgery, including evaluation and post-operative follow-up.

What is the success rate of paediatric heart surgery in India?

Leading Indian paediatric cardiac centres report outcomes comparable with international standards for common operations. The risk depends on the type of defect and the child's condition, and the surgeon will discuss it with you.

Can an older child or adult still be treated for a congenital heart defect?

Yes, many defects can still be repaired in older children and adults, as long as lung blood pressure has not become permanently high. An early evaluation is important.

Can both parents stay with the child in hospital?

Usually one parent can stay with the child in the room, and the other can stay in nearby accommodation. ICU visiting rules vary by hospital.
