Yesterday marked the start of congenital heart disease week. #CHD affects 1 in 100 births. 25% of babies will require surgery or intervention to save their lives. Learn more about defects & how you can help at: www.heart.org/en/health-to... 🧪
Graphic of CHD facts:
1% of newborns are born with a congenital heart defect (CHD) every year
15-20% of CHDs are related to genetic conditions.
A baby’s risk of having a CHD is at least three times more likely if their parents have a CHD. 
More than 2.4 million US children and adults are living with a CHD. 
About 1 in 4 babies with a CHD have a critical CHD. Infants with critical CHDs generally need surgery or other procedures in their first year of life.
CHD treatment helps kids live into adulthood.
