Types of Congenital Heart Defects

Birth defects are grouped into three major categories:

  • structural/metabolic
  • congenital infections
  • other conditions

Birth defects of the heart and circulatory system affect more infants than any other type of birth defect of all infants born each year, approximately 1 in 115 has heart and/or circulatory defects.
