Congenital Heart Defects in Children

Congenital heart defects are problems with the heart's structure that are present at birth. They are the most common type of birth defect, affecting about 8 out of every 1,000 newborns. Congenital heart defects can range from mild to severe and may require surgical or medical intervention.

Types of Congenital Heart Defects

• Ventricular Septal Defect (VSD): A hole in the wall between the two lower chambers of the heart.
• Atrial Septal Defect (ASD): A hole in the wall between the two upper chambers of the heart.
• Tetralogy of Fallot: A combination of four heart defects, including a VSD, pulmonary stenosis, right ventricular hypertrophy, and an overriding aorta.
• Transposition of the Great Arteries: The two main arteries that carry blood away from the heart are reversed.
• Pulmonary Atresia: The pulmonary valve is blocked or missing, preventing blood from flowing to the lungs.

Causes and Risk Factors

The exact cause of congenital heart defects is often unknown. However, certain risk factors may increase the likelihood of a child being born with a heart defect, including:

• Family history of congenital heart defects
• Pregnancy complications, such as diabetes or rubella
• Maternal age over 35 years
• Certain genetic syndromes, such as Down syndrome

Symptoms and Diagnosis

Symptoms of congenital heart defects may include:

• Blue-tinged skin (cyanosis)
• Shortness of breath or difficulty breathing
• Fatigue or weakness
• Poor feeding or failure to gain weight
• Sweating or pale skin

Congenital heart defects are typically diagnosed using a combination of physical examination, medical history, and diagnostic tests, such as:

• Echocardiogram (ultrasound of the heart)
• Electrocardiogram (ECG or EKG)
• Chest X-ray
• Cardiac catheterization

Treatment and Management

Treatment for congenital heart defects depends on the type and severity of the defect. Options may include:

• Surgical repair or replacement of the affected heart structure
• Medications to manage symptoms, such as diuretics or beta blockers
• Catheter-based interventions, such as balloon angioplasty or stenting
• Heart transplantation in severe cases

Prognosis and Outlook

The prognosis for children with congenital heart defects has improved significantly over the past few decades. With advances in medical and surgical treatment, many children with heart defects can lead active and normal lives. However, some may require ongoing medical care and monitoring to manage their condition.
