Congenital heart defects are structural problems arising from abnormal formation of the heart or major blood vessels. At least 18 distinct types of congenital heart defects are recognized, with many additional anatomic variations. Ongoing progress in diagnosis and treatment (surgery and heart catheterization) makes it possible to treat most defects, even those once thought to be hopeless.
