DID YOU KNOW? The word “congenital” means existing at birth. The terms “congenital heart defect” and “congenital heart disease” are often used to mean the same thing, but “defect” is more accurate. This kind of heart ailment is a defect or abnormality, not a disease. A congenital heart defect (CHD) results when the heart, or blood vessels near the heart, don’t develop normally before birth.
