Overview
Congenital heart disease means a baby is born with a structural problem in the heart or nearby blood vessels. These changes can affect blood flow through the heart, to the lungs, or to the rest of the body. There are many types, including holes between heart chambers, narrowed valves, and more complex conditions that change how the heart is built.
Key Symptoms
Symptoms depend on the type and severity of the heart defect. In babies, signs may include fast breathing, poor feeding, sweating with feeds, bluish lips or skin, or poor weight gain. In older children and adults, symptoms can include tiredness, shortness of breath, fainting, chest discomfort, swelling, or trouble keeping up with physical activity. Some people have no clear symptoms and learn about it during a checkup or test.
Causes and Risk Factors
Congenital heart disease happens when the heart does not develop in the usual way during pregnancy. Often, the exact cause is not known. Some cases are linked with genetic changes, certain syndromes, infections during pregnancy, uncontrolled diabetes during pregnancy, or exposure to alcohol, tobacco, or some medicines. Having one child or parent with a congenital heart defect can also raise the chance in some families.
Who Is Affected
Congenital heart disease affects babies, children, and adults around the world. Some defects are detected during pregnancy or soon after birth, while milder forms may not be found until later in life. Because treatment has improved, many children born with congenital heart disease now live well into adulthood.
Prevention
Not all congenital heart defects can be prevented. Before and during pregnancy, regular prenatal care, vaccination as advised, avoiding alcohol and tobacco, and discussing all medicines with a healthcare professional may help lower some risks. Managing long-term health conditions such as diabetes before and during pregnancy is also important.
Diagnosis and Tests
Doctors may suspect congenital heart disease based on symptoms, a heart murmur, low oxygen levels, or screening tests. It can be diagnosed before birth with fetal ultrasound and fetal echocardiography, or after birth with pulse oximetry, echocardiography, chest imaging, electrocardiogram, and sometimes cardiac catheterization or advanced scans. The tests used depend on the person’s age and the suspected heart defect.
Treatment Categories
Treatment depends on the exact defect and how much it affects blood flow and oxygen levels. Some people only need monitoring, while others may need medicines, catheter-based procedures, surgery, or several treatments over time. Follow-up with specialists is important because needs can change during childhood, adolescence, pregnancy, and adulthood.
Living With It
Living with congenital heart disease often means regular checkups and learning the warning signs of complications. School, work, exercise, travel, and pregnancy planning may need special guidance based on the type of heart defect. Emotional support can also matter, especially for children, parents, and adults managing long-term care.
When to Seek Medical Care
Seek medical care if a baby has trouble feeding, poor weight gain, fast breathing, sweating with feeds, or looks unusually pale or blue. Older children and adults should get medical advice for unexplained tiredness, shortness of breath, fainting, swelling, bluish skin, or reduced ability to exercise. People with known congenital heart disease should keep regular follow-up appointments even when feeling well.
When It May Be an Emergency
Get urgent help right away if a baby or child has severe breathing trouble, blue or gray lips or skin, collapse, unresponsiveness, or a seizure. Emergency care is also needed for chest pain with fainting, severe shortness of breath, sudden confusion, or signs that oxygen levels are dangerously low. If symptoms are severe or rapidly getting worse, use local emergency services immediately.
