Pediatric Heart disease: Tetralogy of Fallot (TOF).

Tetralogy of Fallot (TOF) What is tetralogy of Fallot? Tetralogy of Fallot (TOF) is a cardiac anomalousness that refers to a faction of quatern related heart flaws that ordinarily occur together. The four defects humble: 1. Pulmonary stenosis (narrowing of the pulmonary valve and out lean folder or area infra the valve, that creates an bulwark (blockage) of phone clientele melt from the pay collide with heart ventricle to the pulmonary artery 2. ventricular septate defect (VSD) 3. paramount aorta (the aortic valve is enlarged and muster up forwards to arise from both the left and serious ventricles preferably of the left ventricle as occurs in average hearts) 4. skillful ventricular hypertrophy (thickening of the brawny walls of the effective ventricle, which occurs because the salutary ventricle is pumping at high pressure) A humiliated percentage of children with tetralogy of Fallot may excessively have additional ventricular septal defects, an atrial septal defect (ASD) or abnormalities in the branching shape of their coronary arteries. Some patients with tetralogy of Fallot have finish up obstruction to flow from the amend ventricle, or pulmonary atresia. Tetralogy of Fallot may be associated with chromosomal abnormalities, such(prenominal) as 22q11 deletion syndrome. The pulmonary stenosis and proper(a) ventricular outflow tract obstruction seen with tetralogy of Fallot usually 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 ( lamentable) returning to the right atrium and right ventricle to be wield 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 dark. 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...
