Many babies are born with defects of the heart, traced to chromosome defects, maternal infections, or the use of toxic agents. Two types of heart disease are seen. One is called cyanotic, because of the characteristic “blue baby” who has a dusky color to the lips, hands, or a general cyanosis. The most common of these is called the Tetralogy of Fallot, and includes four basic cardiac defects requiring specialized study for diagnosis. A number of surgical procedures have been devised to correct the congenital defects of the heart, reducing the mortality and extending the life of otherwise doomed children.Noncyanotic heart disease such as ventricular or atrial septal defects and stenosis of the pulmonary valves describe defects in other parts of the heart. These conditions create an extra burden for the heart and if severe, may result in heart failure. Patent ductus arteriosis is another condition in which a normal shunting mechanism present in fetal life fails to close after birth.Surgical operations are being refined to deal with these problems and correct them early, to permit normal growth and activity in the young child.
