Introduction
Congenital heart disease refers to structural abnormalities of the heart that are present from birth. It is the most common type of birth defect globally, affecting approximately 1 in 100 newborns. Some forms are detected during pregnancy or shortly after birth, while others are not identified until childhood or even adulthood.
Congenital heart disease treatment in India has advanced significantly over the past two decades, with specialist centres now capable of managing the full spectrum of congenital cardiac conditions – from straightforward defects repaired with a single procedure to complex, multi-staged surgeries for the most severe forms of the disease.
This guide explains the main types of congenital heart disease, the treatment options available, and how Sri Lankan patients – both children and adults – can access specialist care at Amrita Hospitals.
What Is Congenital Heart Disease?
Congenital heart disease (CHD) encompasses a wide range of structural heart abnormalities that develop during foetal development. These may involve:
- The walls between the heart’s chambers (septa)
- The valves that control blood flow through the heart
- The major blood vessels entering and leaving the heart
- The overall structure and arrangement of the heart’s chambers
The severity of CHD varies enormously. Some defects are minor and may close on their own or require no treatment. Others are complex and require surgery in the newborn period to sustain life. Many fall between these extremes – causing symptoms and affecting cardiac function, but amenable to planned surgical or catheter-based repair.
What Are the Most Common Types of Congenital Heart Disease?
Simple Defects
- Atrial septal defect (ASD) – a hole between the two upper chambers (atria) of the heart. Small ASDs may close spontaneously; larger ones require closure, either surgically or via a catheter-based device
- Ventricular septal defect (VSD) – a hole between the two lower chambers (ventricles). The most common congenital heart defect. Small VSDs often close on their own; significant ones require repair
- Patent ductus arteriosus (PDA) – a blood vessel that connects the aorta and pulmonary artery, normally closing shortly after birth. When it remains open, it can cause heart strain and requires closure
- Pulmonary stenosis – narrowing of the pulmonary valve, restricting blood flow from the heart to the lungs
Complex Defects
- Tetralogy of Fallot – a combination of four cardiac abnormalities, the most common cyanotic congenital heart defect. Requires surgical repair, typically in infancy
- Transposition of the great arteries (TGA) – the aorta and pulmonary artery are switched in position. A life-threatening condition requiring surgery in the newborn period
- Coarctation of the aorta – narrowing of the main artery carrying blood from the heart to the body
- Hypoplastic left heart syndrome (HLHS) – the left side of the heart is severely underdeveloped. Requires a series of staged surgical procedures
- Total anomalous pulmonary venous connection (TAPVC) – the pulmonary veins drain to the wrong location
- Ebstein’s anomaly – a malformation of the tricuspid valve
- Single ventricle conditions – conditions where only one functional ventricle is present, requiring multi-staged palliative surgical management
How Is Congenital Heart Disease Diagnosed?
In Infants and Children
- Foetal echocardiography – ultrasound of the foetal heart, allowing detection of many CHDs during pregnancy
- Echocardiography (cardiac ultrasound) – the primary diagnostic tool, providing real-time imaging of the heart’s structure and function
- Chest X-ray – may show cardiac enlargement or abnormal lung vascularity
- Electrocardiogram (ECG) – assesses the electrical activity of the heart
- CT angiography and MRI – used for detailed anatomical assessment of complex defects and major vessels
- Cardiac catheterisation – an invasive procedure used to measure pressures within heart chambers and across defects, and to assess suitability for certain interventional procedures
In Adults with Previously Undiagnosed or Previously Treated CHD Adults may present with symptoms including breathlessness, reduced exercise tolerance, palpitations, or incidentally detected abnormalities on routine examination. Full cardiac evaluation including echocardiography, ECG, and often cardiac MRI is performed.
What Treatment Options Are Available?
Catheter-Based (Interventional) Procedures Many congenital heart defects can now be closed or repaired without open surgery, using catheter-based techniques:
- ASD closure – using a device delivered through a catheter inserted via a vein in the leg, deployed to close the defect under imaging guidance
- VSD closure – catheter-based closure is possible for selected VSDs
- PDA closure – coil or device closure via catheter
- Balloon valvuloplasty – for pulmonary stenosis, a balloon is inflated across the narrowed valve to widen it
- Balloon angioplasty and stenting – for coarctation of the aorta
These catheter-based procedures avoid the need for open-heart surgery in many patients, resulting in shorter hospital stays and faster recovery.
Surgical Repair Open surgery remains necessary for complex defects and for situations where catheter-based approaches are not feasible:
- VSD and ASD repair – patch closure of defects under cardiopulmonary bypass
- Tetralogy of Fallot repair – closure of the VSD and widening of the right ventricular outflow tract
- Arterial switch operation – for transposition of the great arteries, performed in the newborn period
- Glenn and Fontan procedures – staged surgical palliation for single ventricle conditions
- Valve repair or replacement – for significant valve abnormalities
- Coarctation repair – surgical resection and reconstruction
Amrita Hospitals’ Specific Capabilities Amrita Hospitals has a dedicated Adult Congenital Heart Disease Clinic – the first of its kind in India – reflecting the growing recognition that CHD is a lifelong condition requiring specialist management well beyond childhood. The hospital also operates a Comprehensive Fetal Cardiac Centre for assessment and planning from the prenatal stage.
Congenital Heart Disease in Adults: What Sri Lankan Patients Should Know
Advances in paediatric cardiac surgery mean that the majority of children born with congenital heart disease now survive to adulthood. Many of these adults require ongoing specialist cardiac follow-up – not because their condition has returned, but because repaired congenital hearts often develop new challenges over time.
Adults with CHD may experience:
- Residual defects or leaks following earlier repair
- Valve problems developing years after childhood surgery
- Arrhythmias (abnormal heart rhythms) that become more common with age
- Heart failure related to the long-term strain of a repaired but structurally abnormal heart
- Pulmonary hypertension (elevated blood pressure in the lungs)
Sri Lankan adults who were treated for a congenital heart condition in childhood and have not had recent cardiac review are encouraged to seek a formal evaluation. Additionally, adults who were never diagnosed with CHD but experience unexplained breathlessness, palpitations, or reduced exercise capacity should have this investigated – some defects such as ASD are commonly diagnosed for the first time in adulthood.

What Is Recovery Like After Congenital Heart Surgery?
Recovery depends on the type of procedure and the patient’s age and overall condition:
After Catheter-Based Procedures
- Hospital stay: typically 1 to 2 days
- Return to normal activities: within 1 to 2 weeks in most cases
- Follow-up echocardiography required to confirm complete closure or adequate result
After Open Heart Surgery in Children
- ICU stay: typically 2 to 5 days, depending on complexity
- Total hospital stay: 7 to 14 days
- Recovery at home: 4 to 6 weeks before return to school
- Follow-up echocardiography and cardiac review at regular intervals throughout childhood and into adulthood
After Open Heart Surgery in Adults
- Hospital stay: 7 to 10 days
- Return to light activities: 4 to 6 weeks
- Full recovery: 2 to 3 months, with cardiac rehabilitation recommended

Frequently Asked Questions
Can a congenital heart defect be left untreated if it causes no symptoms? Some minor defects – such as small VSDs or small ASDs – may not require treatment and can be monitored. However, even asymptomatic defects should be formally evaluated by a cardiologist, as some can cause long-term complications including arrhythmias, pulmonary hypertension, or increased stroke risk if left unaddressed.
Is it safe for a woman with congenital heart disease to become pregnant? This depends on the type and severity of the defect, and whether it has been repaired. Many women with CHD can have safe pregnancies with appropriate specialist monitoring. Some conditions carry significant pregnancy risk and require pre-conception counselling. A formal assessment with a specialist in adult congenital heart disease is essential before planning pregnancy.
At what age is it best to repair a congenital heart defect? The optimal timing varies by defect type. Some conditions require repair in the newborn period to be life-sustaining. Others are repaired electively in infancy or early childhood. Some defects are best managed with a watch-and-wait approach and repaired only if they progress. The treating team will advise on the optimal timing for your child’s specific condition.
Can adults be treated for previously undiagnosed congenital heart disease? Yes. Many congenital defects – including ASD, bicuspid aortic valve, and mild coarctation – are sometimes not diagnosed until adulthood. Treatment options including catheter-based closure or surgical repair are available for adults, and outcomes are generally good when the condition is identified and treated before complications develop.
What long-term follow-up is needed after congenital heart repair? All patients with repaired congenital heart disease require lifelong cardiac follow-up, even after successful repair. This typically involves periodic echocardiography, ECG, and specialist review. The frequency of follow-up depends on the complexity of the original defect and the type of repair.
Can Sri Lankan patients access a remote opinion before travelling? Yes. In many cases, echocardiography reports, surgical records, and imaging can be shared digitally for an initial assessment by the congenital heart disease team at Amrita Hospitals before travel is arranged.
