Congenital heart defects in children

Congenital heart defects in children - Causes and Risk Factors

The heart begins to develop and starts beating during the first six weeks of pregnancy. During this time period, the heart’s major blood vessels also begin to take shape. In addition, it is at this point in the baby's development that heart defects may begin to develop.

Most congenital heart defects result from complications early in the heart development during childhood. While the cause for most cases is unknown, certain genetic and environmental factors may play a role. These risk factors include:

Diabetes
Drinking alcohol during pregnancy
Smoking during pregnancy
Heredity

Cardiology
