Pediatric Heart disease: Tetralogy of Fallot (TOF).

Tetralogy of Fallot (TOF) What is tetralogy of Fallot? Tetralogy of Fallot (TOF) is a cardiac anomaly that refers to a combination of quartette related heart defects that commonly occur to receiveher. The four defects bewilder: 1. Pulmonary stenosis (narrowing of the pulmonary valve and aside lean portion or area below the valve, that creates an hinderance (blockage) of phone profligate flow from the pay off ventricle to the pulmonary arterial blood vessel 2. Ventricular septate defect (VSD) 3. prevailing aorta (the aortic valve is enlarged and come forwards to arise from both the left and dependable ventricles instead of the left ventricle as occurs in medium hearts) 4. Right ventricular hypertrophy (thickening of the muscular walls of the effective ventricle, which occurs because the skillful ventricle is pumping at high pressure) A small share of children with tetralogy of Fallot may also have additional ventricular septate defects, an atrial septal defect (ASD) or abnormalities in the leg shape of their coronary arteries. Some patients with tetralogy of Fallot have complete obstruction to flow from the right ventricle, or pulmonary atresia. Tetralogy of Fallot may be associated with chromosomal abnormalities, such as 22q11 deletion syndrome. The pulmonary stenosis and right ventricular outflow tract obstruction seen with tetralogy of Fallot normally limits argumentation flow to the lungs. When blood flow to the lungs is restricted, the combination of the ventricular septal defect and overriding aorta allows oxygen-poor blood (blue) return to the right atrium and right ventricle to be pumped out the aorta to the body. This shunting of oxygen-poor blood from the right ventricle to the body results in a diminution in the arterial oxygen saturation so that babies appear cyanotic, or blue. The cyanosis occurs because oxygen-poor blood is darker and has a blue color, so that the lips and come up appear blue. The extent of...
