How serious is the problem?
Congenital heart defects are the most common birth defect and are the number one cause of death from birth defects during the first year of life. Nearly twice as many children die from congenital heart disease in the United States each year as die from all forms of childhood cancers combined. In 2005, 192,000 life-years were lost before age 55 in the United States due to congenital heart disease. In 2004, hospital costs totaled $2.6 billion.
