Below you will find several interesting facts you may or may not already know about these life-threatening and life-altering defects.
- Congenital heart defects (CHDs) occur when a baby's heart fails to form properly during early pregnancy. In most cases, the cause is unknown, although scientists feel both genetic and environmental factors play a role.Some environmental factors that increase the risk of CHDs include the mother’s use of cocaine, alcohol or certain medications while pregnant. Some maternal medical conditions – such as diabetes – may also increase risk.
- CHDs are the most common birth defect – and the leading cause of birth defect-related deaths.
- CHDs occur more often than Spina Bifida, Down Syndrome or hearing loss – and kill twice as many children as childhood cancer.
- It is estimated that 40,000 babies with CHDs are born in the United States each year – that’s one in every 100 babies.
- Although some babies will be diagnosed at birth, newborns are not routinely screened for CHDs – and pregnant women are not routinely tested for CHDs.
- There are approximately 35 different types of congenital heart defects.
- Some CHDs may be treated with surgery, medicine and/or devices, such as artificial valves and pacemakers. In the last 25 years, advances in the treatment of heart defects have enabled half a million U.S. children with serious CHDs to survive into adulthood.
- Many cases of sudden cardiac death in young athletes are caused by undiagnosed CHDs and childhood-onset heart disease.
- Early detection is critical to the successful treatment of CHDs. Some heart defects can be detected by a routine ultrasound – but the most effective prenatal test is an echocardiogram performed by a Pediatric Cardiologist.
