Congenital heart disease is a problem with the heart's structure and function that is present at birth.
Congenital heart disease (CHD) can describe a number of different problems affecting the heart. It is the most common type of birth defect. Congenital heart disease causes more deaths in the first year of life than any other birth defects.
Congenital heart disease is often divided into two types: cyanotic (blue skin color caused by a lack of oxygen) and non-cyanotic. The following lists cover the most common congenital heart diseases:
These problems may occur alone or together. Most children with congenital heart disease do not have other types of birth defects. However, heart defects can be part of genetic and chromosome syndromes. Some of these syndromes may be passed down through families.
Often, no cause for the heart disease can be found. Congenital heart diseases continue to be investigated and researched. Drugs such as retinoic acid for acne, chemicals, alcohol, and infections (such as rubella) during pregnancy can contribute to some congenital heart problems.
Poorly controlled blood sugar in women who have diabetes during pregnancy has also been linked to a high rate of congenital heart defects.
Symptoms depend on the condition. Although congenital heart disease is present at birth, the symptoms may not appear right away.
Most congenital heart defects are found during a pregnancy ultrasound. When a defect is found, a pediatric heart doctor, surgeon, and other specialists can be there when the baby is delivered. Having medical care ready at the delivery can mean the difference between life and death for some babies.
Which tests are done on the baby depend on the defect, and the symptoms.
Which treatment is used, and how well the baby responds to it, depends on the condition. Many defects need to be followed carefully. Some will heal over time, while others will need to be treated.
Some congenital heart diseases can be treated with medication alone. Others need to be treated with one or more heart surgeries.
Women who are pregnant should get good prenatal care:
Certain genes may play a role in congenital heart disease. Many family members may be affected. Talk to your health care provider about genetic screening if you have a family history of congenital heart disease.
