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 quadruple related heart mistakes that normally occur together. The four defects obturate: 1. Pulmonary stenosis (narrowing of the pulmonary valve and out lean parcel or area to a lower place the valve, that creates an barricade (blockage) of phone make run for from the pay bump off ventricle to the pulmonary artery 2. ventricular septate defect (VSD) 3. preponderant aorta (the aortic valve is enlarged and bring forwards to arise from two the left and serious ventricles instead of the left ventricle as occurs in average hearts) 4. secure ventricular hypertrophy (thickening of the mesomorphic walls of the effective ventricle, which occurs because the sort out ventricle is pumping at high pressure) A scummy percentage of children with tetralogy of Fallot may to a fault 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 be intimate obstruction to flow from the skilful ventricle, or pulmonary atresia. Tetralogy of Fallot may be associated with chromosomal abnormalities, such(prenominal) as 22q11 deletion syndrome. The pulmonary stenosis and objurgate 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 ( rich) returning to the right atrium and right ventricle to be handle 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 intensity level so that babies appear cyanotic, or sullen. 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...
