Congenital Heart Disease (CHD) refers to structural abnormalities of the heart present since birth. Advances in diagnosis, medical care, catheter-based interventions, and surgery have enabled most CHD patients to live long, productive lives with proper management and follow-up.
Common Types of Congenital Heart Disease
- Atrial Septal Defect (ASD)
- Ventricular Septal Defect (VSD)
- Patent Ductus Arteriosus (PDA)
- Pulmonary valve stenosis
- Tetralogy of Fallot
- Coarctation of Aorta
- Complex cyanotic heart diseases
Clinical Presentation
Symptoms depend on defect type and severity:
- Breathlessness or poor weight gain in infants
- Recurrent respiratory infections
- Fatigue and exercise intolerance
- Cyanosis (bluish discoloration)
- Palpitations or heart failure symptoms in adults
Many CHDs remain asymptomatic and are detected incidentally during routine evaluation.
Diagnosis of CHD
- Clinical examination and oxygen saturation
- Echocardiography – primary diagnostic tool
- ECG & Chest X-ray
- Cardiac CT / MRI for complex anatomy
- Cardiac catheterization when intervention is planned
Early diagnosis is crucial to prevent complications such as pulmonary hypertension and heart failure.
Medical Management
Medical therapy is used for:
- Symptom control
- Heart failure management
- Arrhythmia control
- Pulmonary hypertension treatment
- Diuretics
- ACE inhibitors / ARBs
- Beta-blockers
- Pulmonary vasodilators (in selected patients)
- Antibiotic prophylaxis in specific situations
Common medications include:
Medical therapy does not correct the defect but stabilizes the patient until definitive treatment.
Catheter-Based Interventions
Many CHDs can now be treated without open-heart surgery:
- ASD, VSD, PDA device closure
- Balloon Pulmonary Valvotomy
- Balloon Aortic Valvotomy
- Coarctation angioplasty and stenting
- Hybrid procedures for complex defects
- Minimally invasive
- Short hospital stay
- Faster recovery
Advantages:
Surgical Management
Surgery is required when:
- Defects are large or complex
- Catheter intervention is not feasible
- Cyanotic or multi-structural defects exist
Modern surgical outcomes are excellent with early intervention.
Adult Congenital Heart Disease (ACHD)
Many children with CHD now survive into adulthood.
ACHD care focuses on:
- Lifelong follow-up
- Arrhythmia surveillance
- Heart failure prevention
- Pregnancy counseling
- Re-interventions when needed
ACHD patients should be followed by specialized congenital cardiology teams.
Lifestyle, Exercise & Prevention
- Most patients can perform moderate physical activity
- Avoid extreme exertion unless cleared by cardiologist
- Regular vaccinations
- Good dental hygiene to prevent endocarditis
- Genetic counseling when appropriate
