What is a Congenital Heart Defect?
A congenital heart defect is a problem with how the heart forms before birth. It can affect the heart’s walls, valves, or blood vessels, changing how blood flows through the body. Some defects are mild, while others require early medical care.
In many cases, the exact cause is unknown. However, certain factors may increase risk, such as:
- Family history of heart defects
- Genetic conditions
- Illness during pregnancy
- Alcohol or drug exposure before birth
Symptoms
Congenital heart defects can look different from person to person. Some children have noticeable symptoms early, while others may not show signs until later in life.
Common symptoms may include:
- Trouble breathing or rapid breathing
- Fatigue or low energy
- Poor feeding or slow growth in infants
- Chest discomfort
- Dizziness or fainting
- Bluish tint to the lips or skin (low oxygen levels)
How is it diagnosed?
Doctors often detect congenital heart defects through a physical exam and imaging tests. An echocardiogram is commonly used to view the heart’s structure and blood flow.
Additional testing may include:
- Electrocardiogram (ECG) to check heart rhythm
- Cardiac catheterization for detailed evaluation
- Imaging studies to assess blood vessels and function
Some conditions are diagnosed before birth, while others are diagnosed later based on symptoms.
How is it treated?
Treatment depends on the type and severity of the defect. Some mild cases only need regular monitoring, while others require more advanced care.
Common treatment options include:
- Medications to support heart function
- Minimally invasive procedures using catheters
- Surgery to repair or correct structural problems
- Valve repair or replacement when needed
Many children recover well after treatment and go on to live active lives. Ongoing follow-up is important, especially as patients transition into adult care.
