Data and Statistics on Congenital Heart Defects
Congenital heart defects (CHDs) are the most common types of birth defects, and babies born with these conditions are living longer and healthier lives. Find more statistics about CHDs below.
Number of U.S. Babies Born with CHDs
- CHDs affect nearly 1% of―or about 40,000―births per year in the United States.1,2
- The prevalence (the number of babies born with heart defect compared to the total number of births) of some CHDs, especially mild types, is increasing, while the prevalence of other types has remained stable. The most common type of heart defect is a ventricular septal defect (VSD).3,4
- About 25% of babies with a CHD have a critical CHD. Infants with critical CHDs generally need surgery or other procedures in their first year of life. [Read summaryexternal icon]
- The prevalence of all types of CHDs, including critical CHDs, varies by state and by type of defect. [Read summaryexternal icon]
CDC is working with the University of Arizona, Duke University, Emory University, the New York State Department of Health, the South Carolina Department of Health and Environmental Control, and the University of Utah to track individuals with CHDs across the lifespan. Understanding health issues and needs across the lifespan is vital to improving the lives of individuals born with these conditions. [Learn More]
Number of U.S. Children and Adults Living with CHDs
- Currently, there are a number of state-based birth defects programs that track CHDs among newborns and young children, but no tracking system exists to look at the growing population of older children and adults with heart defects.
- To date, other methods have been used to estimate the total number of children and adults with these defects. For example, one study estimated that, in 2010, over 2 million infants, children, adolescents, and adults were living with CHDs in the United States. Researchers estimated that about 1 million U.S. children and about 1.4 million U.S. adults were living with CHDs. Overall, there are slightly more adults living with CHDs than children. To obtain this estimate, researchers used data from administrative healthcare databases in Canada to estimate the prevalence of people living with CHDs and applied this to the U.S. Census data from 2010.

- CHDs are a leading cause of birth defect-associated infant illness and death. [Read articleexternal icon]
- Infant deaths due to CHDs often occur when the baby is less than 28 days old (sometimes called the neonatal period). In a study of neonatal deaths, 4.2% of all neonatal deaths were due to a CHD. [Read article]
- During 1999–2006, there were 41,494 deaths related to CHDs in the United States. This means that CHDs were either the main cause of death or contributed to death in some way. During this time period, CHDs were listed as the main cause of death for 27,960 people. Nearly half (48%) of the deaths due to CHDs occurred during infancy (younger than 1 year of age).

- Survival of infants with CHDs depends on how severe the defect is, when it is diagnosed, and how it is treated. [Read summaryexternal icon]
- About 97% of babies born with a non-critical CHD are expected to survive to one year of age. About 95% of babies born with a non-critical CHD are expected to survive to 18 years of age. Thus, the population of people with CHDs is growing.
- About 75% of babies born with a critical CHD are expected to survive to one year of age. About 69% of babies born with critical CHDs are expected to survive to 18 years of age.
- Survival and medical care for babies with critical CHDs are improving. Between 1979 and 1993, about 67% of infants with critical CHDs survived to one year. Between 1994 and 2005, about 83% of infants with critical CHDs survived to one year.
Illness and Disability
- At least 15% of CHDs are associated with genetic conditions.5,6
- About 20% to 30% of people with a CHD have other physical problems or developmental or cognitive disorders.7,8,9
- Children with CHD are about 50% more likely to receive special education services compared to children without birth defects.10
- The occurrence and severity of a developmental disability or delay increases with how complex the heart defect is. For example, more than 80% of individuals with a mild CHD have no developmental disabilities. However, more than half of those with a more critical type of CHD have some form of disability or impairment. Guidelines for screening, diagnosing, and managing developmental disabilities or delay in children with CHDs have been developed. [Read summaryexternal icon]
- Parents of children with special healthcare needs with heart problems commonly report that their children’s condition prevents them from doing things other children do. Parents reported that these children experience more difficulty with learning, concentration, communication, self-care, and fine and gross motor skills than children with special healthcare needs without heart problems. These children also missed more days of school and participated less in extracurricular activities than children with special healthcare needs without heart problems11. [Read summaryexternal icon]
- Compared to children without a heart condition, children with a heart condition were more likely to have special healthcare needs, including medication needs, physical or speech therapy, and treatment for developmental or behavioral problems. Nearly 60% of children with a current heart condition have special healthcare needs, compared to 20% of children without a heart condition12. [Read summaryexternal icon]
- In the United States, hospital costs for the population of individuals with cardiovascular defects in 2013 were about $6.1 billion. Critical congenital heart defect–associated hospitalizations had the highest mean and median cost of the birth defect categories considered ($79,011 and $29,886, respectively).

- Pediatric hospitalizations with CHDs accounted for approximately $5.6 billion in hospital costs, representing 15.1% of costs for all pediatric hospitalizations in 2009. Hospitalizations with critical CHD accounted for 26.7% of all costs for CHD hospitalizations, with hypoplastic left heart syndrome, coarctation of the aorta, and tetralogy of Fallot having the highest total costs.

- In addition to the medical costs of care for CHDs, families of children with CHDs can face other costs, such as high out-of-pocket expenses, financial problems, greater care-giving hours, quitting or reducing hours at work in order to care for their child, and decreased mental health.

Infant Death Due to Heart Defects
Congenital heart defects are conditions present at birth that can affect the way the heart works. They can cause lifelong disability or death. They are the most common type of birth defect, affecting nearly 40,000 births in the United States each year.
