- Irritability: Especially in infants and young children.
- Difficulty sleeping: Due to breathing difficulties.
- Failure to gain weight: Despite adequate calorie intake.
- Chest congestion: Feeling of heaviness or tightness in the chest.
Diagnostic Tests:
- Echocardiogram: Uses sound waves to create images of the heart and blood vessels.
- Chest X-ray: Provides detailed images of the heart and lungs.
- Electrocardiogram (ECG or EKG): Records the electrical activity of the heart.
- Cardiac catheterization: Involves inserting a catheter into the heart to measure pressures and obtain blood samples.
- Magnetic resonance imaging (MRI): Produces detailed images of the heart and blood vessels using magnetic fields and radio waves.
- Computed tomography (CT) scan: Offers cross-sectional images of the heart and lungs.
- Pulse oximetry: Measures oxygen levels in the blood.
- Exercise stress test: Evaluates heart function during physical activity.
- Blood tests: To check for signs of infection or abnormalities in blood chemistry.
- Lung function tests: Assess lung capacity and function.
- Holter monitor: Records heart activity over a period of time.
- Radionuclide imaging: Uses radioactive tracers to evaluate blood flow and heart function.
- Angiography: Involves injecting contrast dye into the blood vessels to visualize blood flow.
- Pulmonary function tests: Measures lung function and capacity.
- Genetic testing: Identifies specific genetic mutations associated with heart defects.
- Arterial blood gas analysis: Measures levels of oxygen and carbon dioxide in the blood.
- Plethysmography: Measures changes in blood volume.
- Transesophageal echocardiography (TEE): Provides detailed images of the heart using a probe inserted through the esophagus.
- Doppler ultrasound: Assesses blood flow through the arteries and veins.
- Biopsy: In rare cases, a tissue sample may be taken for further analysis.
Treatments:
- Medications:
- Diuretics: To reduce fluid retention and swelling.
- Oxygen therapy: Supplemental oxygen to improve oxygenation.
- Inotropic agents: To improve heart function.
- Anticoagulants: To prevent blood clots.
- Antiarrhythmic drugs: To control irregular heart rhythms.
- Catheter-based interventions:
- Balloon angioplasty: Inflating a balloon to widen the narrowed artery.
- Stent placement: Inserting a mesh tube to keep the artery open.
- Surgery:
- Pulmonary artery reconstruction: Surgical repair of the narrowed artery.
- Pulmonary artery bypass: Redirecting blood flow around the blocked artery.
- Valve replacement: If there are associated valve abnormalities.
- Lung transplantation: In severe cases of pulmonary hypertension or lung damage.
- Lifestyle modifications:
- Healthy diet: Low in sodium and saturated fats.
- Regular exercise: As tolerated, under medical supervision.
- Smoking cessation: Avoiding tobacco smoke exposure.
- Weight management: Maintaining a healthy weight.
- Stress management: Techniques to reduce stress and anxiety.
- Oxygen therapy:
- Continuous or intermittent oxygen supplementation.
- Pulmonary rehabilitation:
- Exercise training and education to improve lung function and overall health.
- Follow-up care:
- Regular monitoring by a cardiologist or pulmonologist.
- Periodic imaging studies to assess disease progression.
- Adjustments to treatment plan as needed.
