Congenital Heart Disease: Clinical Patient Journey
Congenital heart disease (CHD) refers to structural problems in the heart that are present from birth. These may involve the heart’s walls, valves, or major blood vessels. Some conditions are detected in infancy, while others may go unnoticed until adulthood, especially milder defects such as atrial septal defect (ASD) or bicuspid aortic valve.
With advances in cardiology and imaging, most congenital heart conditions can now be managed effectively, allowing patients to lead long, healthy lives.
At The Medical Group of New Jersey, our cardiologists coordinate imaging, monitoring, and, when appropriate, catheter-based or surgical repair, ensuring seamless transition from pediatric to adult cardiac care.
Symptom Onset & Initial Evaluation
Symptoms depend on the type and severity of the defect. Some individuals experience no symptoms until later in life, while others develop:
- Shortness of breath or fatigue, especially with exertion
- Swelling in the legs or abdomen
- Heart murmur detected during a routine exam
- Cyanosis (bluish skin tone) in more severe defects
- Irregular heartbeats or palpitations
Evaluation typically includes:
- Echocardiogram (ECHO): The primary test to visualize heart structure and blood flow.
- Cardiac MRI or CT scan: Provides detailed anatomical mapping.
- Electrocardiogram (ECG): Detects arrhythmias or chamber enlargement.
- Cardiac catheterization: Measures pressures and oxygen levels when surgical planning is needed.
Diagnosis & Common Types
Your cardiologist will determine the specific type of congenital heart defect and whether it requires monitoring or intervention. Common types include:
- Atrial Septal Defect (ASD): A hole between the upper chambers of the heart.
- Ventricular Septal Defect (VSD): A hole between the lower chambers.
- Patent Ductus Arteriosus (PDA): A vessel that fails to close after birth.
- Coarctation of the Aorta: Narrowing of the body’s main artery.
- Tetralogy of Fallot (ToF): A complex defect involving multiple structural changes.
- Bicuspid Aortic Valve: A valve with two flaps instead of three, leading to early wear.
Some defects may resolve spontaneously, while others need repair in childhood or adulthood.
Treatment & Management
Treatment depends on the specific defect and its impact on heart function.
Medical Management:
- Blood pressure and heart rhythm control
- Regular monitoring of heart size and valve function
- Antibiotic prophylaxis in select cases to prevent endocarditis
Interventional or Surgical Repair:
- Catheter-based closure: Minimally invasive repair for ASD, VSD, or PDA
- Balloon angioplasty and stenting: To open narrowed vessels such as the aorta
- Open-heart surgery: For complex or combined defects
- Valve repair or replacement: For significant valve abnormalities
Our cardiologists collaborate with congenital heart surgeons and imaging experts to ensure precision in every treatment plan.
Long-Term Monitoring & Lifestyle
Even after repair, congenital heart disease often requires lifelong follow-up. Ongoing surveillance ensures that repaired areas remain stable and helps detect arrhythmias or valve issues early.
Patients are encouraged to:
- Maintain a heart-healthy lifestyle (balanced diet, regular exercise)
- Avoid smoking and excessive alcohol use
- Discuss family planning with their cardiologist, as pregnancy may require special monitoring
- Attend regular echocardiograms and cardiology visits
At The Medical Group of New Jersey, our Adult Congenital Heart Disease team provides continuous care from adolescence through adulthood, coordinating imaging, interventional cardiology, and preventive care to support long-term heart health.
