Nearly 1 in 100 babies (about 1 percent or 40,000 babies) is born with a heart defect in the United States each year. About 1 in 4 babies born with a heart defect (about 25 percent) has a critical CHD. Some heart defects don’t need treatment or can be treated easily.

## What is the rate of congenital heart disease?

CHDs affect nearly 1% of―or about 40,000―births per year in the United States. 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.

## How many people in the US have congenital heart defects?

Nearly 40,000 infants in the U.S. are born each year with CHDs. CHDs are as common as autism and about twenty-five times more common than cystic fibrosis. Approximately two to three million individuals are thought to be living in the United States with CHDs.

## What population is most affected by congenital heart disease?

Sex Distribution of CHD

The prevalence of all CHD in adults was significantly higher in females than in males (4.55 per 1000 females versus 3.61 per 1000 males; P<0.0001). In those with severe disease, the prevalence was higher in female adults (0.41 per 1000 versus 0.35 per 1000; P=0.0001) but not in female children.

## What is the rarest congenital heart defect?

Truncus arteriosus is a rare type of heart disease that is present at birth (congenital) in which there is a single main blood vessel, rather than the normal two, carrying blood away from the heart.

## Is congenital heart disease dominant or recessive?

There is an overall 3 times increased risk for CHD when a first-degree relative has a CHD. Some heart defects have autosomal-dominant inheritance. This means that with each pregnancy, a parent with the defect has a 50% chance to have a child with the same heart defect. Males and females are equally affected.

## Is congenital heart disease more common in males or females?

CHDs were more common in females than males at all. In the details the frequency of females other than males was more in VSD, PS, PDA and ASD. But, the frequency of males other than females was more in TOF, AS, COA and D-TGA. VSD was the most frequent of CHDs.

## Can you live a normal life with congenital heart disease?

As medical care and treatment have improved, babies and children with congenital heart defects (CHDs) are living longer and healthier lives. Most are now living into adulthood. Ongoing, appropriate medical care can help children and adults with a CHD live as healthy as possible.
