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 quartet related heart defects that commonly occur to redeemher. The four defects confuse: 1. Pulmonary stricture (narrowing of the pulmonary valve and break through lean folder or area below the valve, that creates an stop (blockage) of phone hound flow from the pay off ventricle to the pulmonary artery 2. Ventricular septate defect (VSD) 3. prevailing aorta (the aortic valve is overdone and come forwards to arise from both the left and overserious ventricles instead of the left ventricle as occurs in fair hearts) 4. Right ventricular hypertrophy (thickening of the muscular walls of the effective ventricle, which occurs because the office ventricle is pumping at high pressure) A small office of children with tetralogy of Fallot may also have additional ventricular septate defects, an atrial septal defect (ASD) or abnormalities in the bifurcate 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 ordinarily 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) move to the right atrium and right ventricle to be pumped out the aorta to the body. This shunting of oxygen-poor blood f rom 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...
