Research Paper On Tetralogy Of Fallot

Tetralogy of Fallot is a common congenital heart defect, changing the normal flow of blood through the heart. This rare condition is complex and occurs in about five out of every ten thousand babies. This defect is present in utero, and is caused by the narrowing of the pulmonary artery and a hole between the ventricles. Tetralogy of Fallot consists of four different heart defects, occurring at the once. These abnormalities include: ventricular septal defect, pulmonary stenosis, right ventricle hypertrophy, and an overriding aorta. Babies who have tetralogy of fallot have episodes of cyanosis starting from birth. When the baby begins to breathe on its own, the baby will turn cyanotic, due to the low oxygen level in the blood leaving the heart.
