Detailed explanation-1: -Infants with tetralogy of Fallot can have a bluish-looking skin color―called cyanosis―because their blood doesn’t carry enough oxygen. At birth, infants might not have blue-looking skin, but later might develop sudden episodes of bluish skin during crying or feeding. These episodes are called tet spells.
Detailed explanation-2: -What is Cyanosis in Infants and Children? Cyanosis refers to a bluish-purple hue to the skin. It is most easily seen where the skin is thin, such as the lips, mouth, earlobes and fingernails. Cyanosis indicates there may be decreased oxygen attached to red blood cells in the bloodstream.
Detailed explanation-3: -Tetralogy of Fallot is one of the commonest cyanotic heart defects. The severity of cyanosis is determined by the degree of obstruction to pulmonary blood flow. Prevention of cyanotic spells is key for safe anaesthesia. Late complications include arrhythmias, pulmonary regurgitation and right heart failure.
Detailed explanation-4: -Tetralogy of Fallot is a combination of four congenital heart defects. The four defects are a ventricular septal defect (VSD), pulmonary stenosis, a misplaced aorta and a thickened right ventricular wall (right ventricular hypertrophy). They usually result in a lack of oxygen-rich blood reaching the body.
