What causes heart defects in unborn babies?
Some babies have heart defects because of changes in their individual genes or chromosomes. CHDs also are thought to be caused by a combination of genes and other factors, such as things in the environment, the mother’s diet, the mother’s health conditions, or the mother’s medication use during pregnancy.
Can a baby with a heart defect survive?
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.
How common are heart defects in fetuses?
