Pediatric Cardiology plays a major role in the diagnosis of congenital heart defects, performing diagnostic procedures such as echocardiograms, cardiac catheterizations, and for the ongoing management of the sequel of heart disease in infants, children and adolescents. The inclined graph of neonates with congenital heart defects referred to the neonatal intensive care unit reflects the increasing awareness that the defects may be present. Chest radiography and ECG rarely used in the neonatal diagnosis. Congestive heart failure in the fetus, or hydrops, can be detected by performing fetal echocardiography. Nursing and care for pediatric cardiac patients also plays an important role for the cure of pediatric cardiac patients.
