Squatting in tetralogy of fallout
Septum is not in correct anatomical position, with four consequences. 1-pulmonic stenosis 2- right ventricular hypertrophy 3- overriding aorta (sitting on two ventricles) 4 - ventricular septal defect
Squatting increases afterload, which makes it harder for deoxygenated blood to cross over from the right ventricle to the left ventricle, which allows more oxygenated blood to go thru aorta and decreases cyanosis. So babies that are cyanotic and squatting, with relief of cyanosis, is diagnostic of tetralogy of fallout
What are the four primary pathophysiologies associated with Tetralogy of Fallot?
PROV- Pulmonic stenosis, Right ventricular hypertrophy, Overriding aorta, Ventricular septal defect
It is a right to left shunt. So deoxygenated blood leaks to left side and goes back to body without oxygen. Cyanosis results in blue babies.
True or False: Tetralogy of Fallot is a congenital heart defect.
True
Fill in the blank: The most common cyanotic congenital heart defect is __________.
Tetralogy of Fallot
Which defect in Tetralogy of Fallot involves a narrowing of the outflow tract from the right ventricle?
Pulmonary stenosis
What is the typical surgical treatment for Tetralogy of Fallot?
Surgical repair typically involves closure of the ventricular septal defect and relief of the pulmonary stenosis.
