Congenital Heart Disease in Adults – Diagnosis and Treatment

Diagnosis

Medical Tests Used for Detection

Diagnosing congenital heart problems in adults often involves both a physical exam and a range of medical tests. The healthcare provider listens for unusual heart sounds, reviews symptoms, and asks questions about medical and family history.

Specific tests help get a clear picture of how the heart works and identify the exact type of heart defect.

Common Tests for Heart Defects

Here are some of the main tests that detect congenital heart conditions:

Test TypePurpose and What It Shows
Electrocardiogram (ECG)Checks the heart’s electrical signals. Detects arrhythmias and can suggest some types of heart defects.
Chest X-RayShows the shape and size of the heart and lungs. Can suggest an enlarged heart or extra fluid.
Pulse OximetryMeasures oxygen in the blood. Low oxygen could point to heart or lung problems.
EchocardiogramUses sound waves to show heart structure and movement. Can identify septal defects (like atrial septal defect or ventricular septal defect), valve issues, and how well blood is moving through the heart.
Transesophageal Echocardiogram (TEE)Provides more detailed heart images by putting a probe in the esophagus. Helpful for looking closely at valves, like a bicuspid aortic valve, and the aorta.
Exercise Stress TestChecks how the heart works during physical activity. Can show problems with blood flow that only appear during exercise.
Heart MRI (Cardiac MRI)Gives detailed pictures of the heart’s structure. Measures the size of chambers and helps find problems like tetralogy of Fallot and other complex defects.
Cardiac CatheterizationA thin tube goes through blood vessels into the heart. Measures pressure and oxygen levels, and finds blocked or abnormal vessels. Doctors can treat some defects during the same procedure.

Key Conditions These Tests Can Find

  • Atrial Septal Defect (ASD): Extra opening in the upper heart chambers.
  • Ventricular Septal Defect (VSD): Hole between the lower chambers.
  • Patent Foramen Ovale: Small hole in the atrial wall, usually closes after birth.
  • Patent Ductus Arteriosus: Vessel that stays open after birth, meant to close soon after.
  • Bicuspid Aortic Valve: Valve has two flaps instead of three.
  • Tetralogy of Fallot: A combination of four heart defects.

Other Important Information

  • Fetal Echocardiogram: Doctors use this test to find heart problems before birth.
  • X-ray and Echocardiography: These tests help both adults and children by spotting heart changes or septal defects.
  • ECG and Pulse Oximetry: Providers often use these together to check heart rhythm and oxygen flow.

Doctors often combine results from these tests to make a clear diagnosis. No single test works for every patient, so doctors choose the most useful ones based on symptoms and suspected condition.

Treatment

Medicines

Adults with congenital heart disease may need medication to help their heart work more efficiently. These drugs can reduce symptoms and help manage high blood pressure in the lungs (pulmonary hypertension) or prevent blood clots.

Some people take medication to control heart rhythm problems, such as arrhythmias, or to lower the risk of heart infections like endocarditis.

Common types of medicines include:

Type of MedicationWhat It Does
Blood thinnersReduces the risk of blood clots
Beta-blockersSlows heart rate, lowers blood pressure
Anti-arrhythmic medicinesHelps maintain a normal heartbeat
DiureticsRemoves extra fluid from the body
Others for Pulmonary HypertensionLowers pressure in the lung arteries

Each person’s medicine plan depends on their specific condition and needs.

Surgical and Device Procedures

Some people need a procedure or operation to manage their heart defect, especially if the defect is complex or causes severe symptoms.

Common treatment options include:

  • Implantable Devices: Pacemakers or implantable cardioverter-defibrillators (ICDs) control abnormal heart rhythms.
  • Catheter-Based Care: Doctors use thin tubes (catheters) to repair certain heart defects without traditional surgery. They insert the catheter through a blood vessel, often in the groin, and use small tools to fix the problem area in the heart.
  • Surgery: When catheter procedures are not possible, surgeons perform open-heart surgery. The type of surgery depends on the defect and might involve repairing a narrowed aorta (coarctation of the aorta) or fixing heart valves.
  • Heart Transplant: For severe heart disease that other treatments cannot fix, doctors may recommend a heart transplant.

People with complicated heart conditions might need several procedures or surgeries during their lifetime.

Ongoing Checkups and Monitoring

Most adults with congenital heart disease need lifelong checkups, even after successful surgery. Regular visits with a doctor experienced in adult congenital heart conditions are important. A congenital cardiologist usually provides this care.

Routine health monitoring includes:

  • Blood pressure checks
  • Imaging studies (like ultrasound of the heart)
  • Blood tests
  • Heart rhythm checks

Some adults develop new problems, such as endocarditis or narrowing of arteries, so regular follow-up care remains essential.

Healthy Living and At-Home Tips

  • Stick to a balanced diet. Choose heart-healthy foods low in saturated fats, trans fats, sodium, and added sugars. Focus on fruits, vegetables, whole grains, lean proteins, and healthy fats to support cardiovascular health and manage blood pressure and cholesterol levels.
  • Increase light physical activity. Engage in regular, low- to moderate-intensity exercise as advised by your healthcare provider. Activities like walking, swimming, or yoga can improve circulation, energy levels, and overall heart function without placing excess strain on the heart.
  • Take medicines as directed. Follow your prescribed treatment plan carefully. Medications may include blood pressure regulators, antiarrhythmic drugs, anticoagulants, or other therapies depending on your specific heart condition. Do not skip doses or stop medications without medical guidance.
  • Attend regular doctor visits. Schedule consistent checkups with a cardiologist familiar with adult congenital heart disease. Routine monitoring helps detect complications early, track changes in heart function, and adjust treatment plans as needed.
  • Limit stress when possible. Chronic stress can strain the heart. Practice relaxation techniques such as deep breathing, meditation, or mindfulness. Prioritize sleep and build healthy boundaries to manage work and life stressors more effectively.
  • Avoid tobacco and limit alcohol. Tobacco use and excessive alcohol can worsen heart problems. Avoid smoking and exposure to secondhand smoke, and consult your doctor about safe alcohol limits or whether complete avoidance is recommended.
  • Stay informed and connected. Educate yourself about your specific condition and consider joining support groups or communities for adults with congenital heart disease. Sharing experiences and resources can improve mental well-being and offer valuable coping strategies.

Finding Support and Managing Day-to-Day Challenges

Talking with others who have congenital heart disease can offer comfort and valuable advice. Support groups make it easier to share feelings and find encouragement.

Ask your healthcare team about local or online groups that may be available. Learning about the specific heart condition is important.

Key information people should know includes:

  • The exact type of heart defect and treatments received
  • Symptoms to watch for
  • How often to get checkups
  • Medication details and possible side effects
  • Ways to avoid heart infections
  • Exercise or work limitations
  • Family planning and birth control
  • Health insurance options

Having this knowledge helps people feel more in control. Keeping track of personal health information in a notebook or digital app can also be useful.

Getting Ready for Your Visit

How to Prepare

Before you go to an appointment with a cardiologist who treats adult congenital heart disease, being organized helps. Here are some steps to follow:

  • Ask about special steps before your visit. Call ahead to find out if you need to fast or stop any medication before your checkup or heart tests.
  • Write down your symptoms. List all symptoms you have experienced, even if they seem unrelated to your heart or are mild. Note when each symptom started.
  • Gather key health information. Make a record of:
    • Personal and family history of congenital heart defects.
    • Any treatments or surgeries you had as a child for congenital heart disease.
    • All medications, supplements, and vitamins you use, including the dose and frequency.
  • Prepare questions. Bring written questions for the healthcare team. Here are samples:
    • How often will I need to have my heart checked?
    • Do any of the tests require special preparation?
    • How do you watch for new or worsening heart issues?
    • Will my children be at risk for congenital heart defects?
    • Are there foods or activities I should avoid?
    • How do I manage congenital heart disease along with other health problems?
  • Bring your records. If possible, bring any past medical records, including test results related to congenital heart disease.

Being organized helps you make the most of your visit and gives your healthcare team the full picture of your health.
