Congenital Heart Disease (CHD) refers to structural abnormalities of the heart that are present since birth. These defects develop during the early stages of fetal growth and may involve the heart walls, valves, blood vessels or chambers of the heart. Congenital heart disease can range from simple conditions that may not require treatment to complex defects needing multiple procedures or surgery.
Congenital heart disease is one of the most common birth defects worldwide. Thousands of children are born with heart defects every year in India. With advances in diagnosis and treatment, most children with congenital heart disease can now survive into adulthood and lead productive lives.
Some congenital heart defects may be detected during pregnancy or soon after birth, while others may remain unnoticed until childhood or even adulthood. Common congenital heart defects include:
- Hole in the heart (ASD, VSD, PDA)
- Tetralogy of Fallot
- Valve abnormalities
- Coarctation of aorta
- Complex cyanotic heart diseases
Symptoms depend on the type and severity of the defect. Babies and children may present with:
- Fast breathing or breathlessness
- Poor feeding or poor weight gain
- Recurrent respiratory infections
- Bluish discoloration of lips or fingers (cyanosis)
- Excessive sweating during feeding
- Fatigue and reduced activity
In adults, some congenital heart diseases may present later with breathlessness, palpitations, stroke or heart failure symptoms.
The exact cause is often unknown, though genetic factors, maternal infections,uncontrolled diabetes, certain medications and family history may increase the risk. Many congenital heart defects occur without any identifiable cause.
Diagnosis is usually made with clinical examination, ECG, chest X-ray and echocardiography. In selected cases, CT scan, MRI or cardiac catheterization may be required for detailed evaluation.
Treatment depends on the specific defect and severity. Some small defects may close spontaneously and require only observation. Others may need medications, catheter-based interventions or open-heart surgery. Modern minimally invasive procedures now allow treatment of many congenital defects without major surgery.
Early diagnosis and timely treatment are extremely important, as they can significantly improve growth, quality of life and long-term outcomes for both children and adults with congenital heart disease.
