Tetralogy of Fallot is one of the most common congenital heart disorders.Congenital heart defects are the leading cause of birth defect- related deaths [3] , infants morbidity and mortality[1,3] , heart failure and dilated cardiomyopathy.[2] Tetralogy of Fallot may be associated with chromosomal abnormalities, such as 22 q11 deletion syndrome. [1,2] It occurs in about 5 out of every 10.000 babies[1,2]. The defect affects boys and girls equally[2,3] . Tetralogy of Fallot is typically treated by open heart surgery in the first year of life.[1] The timing of the surgery will depend on how narrow the pulmonary artery is. In untreated cases, TOF carries a 35 % mortality rate in the first year of life, and a 50% mortality rate in the first three years of life. Surgery is preferably done at or about 12 months of age. Although congenital heart defects are the leading causes of birth-related deaths, infants morbidity and mortality, the experience shows, that in case of the right treatment the baby will be healthy and will have a excellent quality of life.
