Congenital Heart Disease Treatment in Delhi

Access to Congenital Heart Disease Treatment in Delhi is critical for children and adults born with structural heart defects, where timely diagnosis and specialised surgical care can significantly improve survival and long-term quality of life.

Congenital heart disease (CHD) is the most common category of birth defects in India, accounting for approximately 28% of all congenital malformations.An estimated 240,000 children are born with CHD in India every year, reflecting a birth prevalence of around 9 per 1,000 live births. Of these, nearly 50,000 children require surgical or catheter-based intervention during infancy. Despite these numbers, access to timely, high-quality congenital heart disease treatment remains concentrated in a handful of specialised centres. Early diagnosis and expert surgical care are the factors that most significantly determine outcomes.

Dr. Dinesh Kumar Mittal, Senior Cardiac and CTVS Surgeon at Fortis Hospital, Shalimar Bagh, Delhi, is a Pioneer of Neonatal Cardiac Surgery and Aortic Intervention in North India, with over 25 years of dedicated experience in congenital cardiac surgery across all age groups, from neonates to adults. He provides comprehensive evaluation and personalised treatment for the full spectrum of congenital heart conditions, including complex and rare defects.

What Is Congenital Heart Disease?

Congenital heart disease refers to any structural problem with the heart that develops during foetal growth. The term covers a wide range of conditions, from a small hole between two heart chambers that may close on its own, to complex multi-structure defects that require staged surgical repair beginning in the first days of life.

CHD affects the walls, valves, arteries, or veins of the heart. Depending on whether the defect disrupts the oxygen levels in the blood, conditions are broadly classified as acyanotic (normal blood oxygen) or cyanotic (reduced blood oxygen, often causing a bluish tinge to the skin).

Types of Congenital Heart Disease

Understanding which type of congenital heart defect is present is essential before any treatment can be planned. The most commonly treated conditions include:

Acyanotic (Non-Cyanotic) Congenital Heart Defects

These defects allow oxygenated and deoxygenated blood to mix, but blood oxygen levels remain near normal. They include:

• Ventricular Septal Defect (VSD): The most common congenital heart defect in India, present in approximately 5.7 per 1,000 live births in North Indian newborn screening studies. A hole in the wall between the two lower chambers allows blood to leak between them.
• Atrial Septal Defect (ASD): A hole in the wall separating the two upper chambers. Often diagnosed later in childhood or adulthood.
• Patent Ductus Arteriosus (PDA): A foetal blood vessel that fails to close after birth, allowing blood to bypass the lungs.
• Aortopulmonary (AP) Window: An abnormal connection between the aorta and pulmonary artery, requiring early surgical correction.
• Pulmonary Stenosis and Aortic Stenosis: Valve defects that obstruct blood flow out of the heart.

Cyanotic Congenital Heart Defects

These are more complex defects where deoxygenated blood bypasses the lungs and enters the body’s circulation, causing low blood oxygen and, in severe cases, a bluish colour of the lips, fingertips, or skin (cyanosis).

• Tetralogy of Fallot (ToF): the most common cyanotic congenital heart defect, involving four structural abnormalities.
• Transposition of the Great Arteries (TGA): The aorta and pulmonary artery are switched, requiring urgent surgical correction in the newborn period.
• Total Anomalous Pulmonary Venous Connection (TAPVC): The pulmonary veins drain abnormally, bypassing the left heart entirely.
• Tricuspid Atresia and Single Ventricle Defects: Conditions where one ventricle is absent or underdeveloped, requiring staged surgical palliation.
• Blue Baby Syndrome: A collective term for cyanotic conditions causing low oxygen in the newborn.

Congenital Heart Disease Symptoms: What to Look For?

Congenital heart disease symptoms vary considerably depending on the type and severity of the defect. Some infants present with obvious signs at birth; others are not diagnosed until childhood or even adulthood, when incidental findings on examination or investigation prompt further testing.

Not all congenital heart defects produce symptoms early on. A heart murmur detected by a doctor, or an abnormal finding on a chest X-ray or ECG, is often the first indication that further investigation is needed.

How Is Congenital Heart Disease Diagnosed?

Accurate Congenital Heart Disease diagnosis requires a combination of clinical assessment and specialist imaging.

After birth or at any age, the following investigations form the basis of CHD diagnosis:

• Echocardiography (2D Echo): The most important test for congenital heart disease. It uses ultrasound to create detailed images of the heart’s structure, walls, valves, and blood flow in real time. It is painless, safe at all ages, and provides the information needed to plan treatment.
• Chest X-Ray and ECG: Used to assess heart size, lung congestion, and the heart’s electrical activity.
• CT or MR Angiography: Provides detailed three-dimensional imaging of the heart and great vessels, particularly useful for complex defects or pre-operative planning.
• Pulse Oximetry: A simple, non-invasive test measuring blood oxygen saturation, used routinely in newborn screening.
• Cardiac Catheterisation: A catheter-based study providing direct pressure measurements and detailed anatomy, sometimes used for complex CHD or immediately before an interventional procedure.

A foetal echocardiogram performed at 18-22 weeks of pregnancy can detect many major structural defects before birth, allowing time for delivery planning at a centre equipped for neonatal cardiac care.

Congenital Heart Disease Treatment Options in Delhi

Congenital heart disease treatment is determined by the type of defect, the age and size of the patient, the severity of symptoms, and whether other cardiac abnormalities are present. The options range from watchful waiting for small defects, through catheter-based closure procedures, to complex open-heart and neonatal surgery.

1. Medical Management and Monitoring

Not all congenital heart defects require immediate intervention. Small VSDs often close spontaneously in early childhood. In the interim, or where surgery is not yet indicated, medical management focuses on supporting heart function and preventing complications. Medications such as diuretics, digoxin, and ACE inhibitors may be used to control symptoms and reduce the workload on the heart.

2. Catheter-Based (Interventional) Procedures

For suitable defects, minimally invasive catheter-based closure avoids open-heart surgery entirely. A thin tube is guided through the blood vessels to the heart, where a closure device is deployed across the defect.

• ASD Device Closure; for suitable secundum ASDs.
• PDA Device Closure; coil or device closure for persistent PDA.
• Balloon Valvuloplasty; for pulmonary or aortic valve stenosis, a balloon is used to open the narrowed valve without surgical incision.
• Pulmonary Artery Stenting; for narrowing of the pulmonary arteries after prior surgery.

3. Open-Heart Surgery

The majority of significant congenital heart defects require open-heart surgery, typically using cardiopulmonary bypass. The timing, sequence, and technique depend on the specific anatomy. Dr. Dinesh Kumar Mittal performs the full range of congenital cardiac operations, including:

• VSD and ASD Patch Repair: Closure of septal defects using a patch sutured in place.
• Total Correction of Tetralogy of Fallot: Repair of all four components, typically in infancy.
• Arterial Switch Operation: For Transposition of the Great Arteries, ideally within the first two weeks of life.
• TAPVC Repair: Reconnection of the pulmonary veins to the left atrium.
• Rastelli and Senning Procedures: For complex TGA with VSD and pulmonary stenosis.
• Fontan and Glenn Procedures: Staged palliation for single ventricle defects.
• Blalock-Taussig Shunt: An initial palliative procedure to increase blood flow to the lungs in cyanotic conditions.
• Heart Valve Repair or Replacement: For congenital valve abnormalities.
• Pacemaker Implantation: In children with heart block complicating CHD or surgery.
• ECMO Support: Used in critically ill neonates and infants requiring temporary heart and lung support during or after surgery.

Congenital Heart Disease Treatment Cost in Delhi

The cost of congenital heart disease treatment in Delhi varies significantly depending on the type and complexity of the defect, the surgical or interventional procedure required, the patient’s age and overall condition, and the duration of hospital stay including ICU care.

These are indicative ranges. A personalised cost estimate is provided after clinical evaluation and review of echocardiography and imaging reports.

Most health insurance policies in India, including government schemes, cover congenital heart disease surgery under inpatient hospitalisation benefits.

Cashless treatment may be available for eligible policyholders too.
