Congenital Heart Defects

Congenital heart defects (CHDs) are conditions that are present at birth and can affect the structure of a baby’s heart and the way it works. They are the most common type of birth defect. As medical care and treatment have advanced, Infants with congenital heart defects are living longer and healthier lives. Many now are living into adulthood.

Hypoplastic Left Heart Syndrome (HLHS) is a birth defect that affects normal blood flow through the heart. As the baby develops during pregnancy, the left side of the heart does not form correctly. Read more about Hypoplastic Left Heart Syndrome.

Tetralogy of Fallot is a birth defect that affects normal blood flow through the heart. It happens when a baby’s heart does not form correctly as the baby develops during pregnancy. Read more about Tetralogy of Fallot.

Dextro-Transposition of the Great Arteries (d-TGA) is a birth defect of the heart in which the two main arteries carrying blood out of the heart – the main pulmonary artery and the aorta – are switched in position, or “transposed.” Read more about d-TGA.

In order to further refine the data being displayed, some advanced options are available at the state level. Users can filter results by:

  • Infant gender
  • Maternal age group
  • Maternal race/ethnicity

The low frequency of individual births defects means that most county level measures are suppressed due to counts of 5 or less.

Measure Description:

  • The Prevalence per 10K Live Births is the number of live-born infants diagnosed with the selected birth defect per 10,000 live births during the stated five year period.
