How do you remember tetralogy of Fallot?

The acronym “PROVe” can be used to help remember the four specific abnormalities generally associated with TOF: P for pulmonary infundibular stenosis, R for RVH, O for overriding aorta, V for VSD, and the “e” is silent without an associated pathology.

Are there different types of tetralogy of Fallot?

The following 4 diagnostic subgroups of tetralogy of Fallot (TOF) are described [1, 2] : (1) tetralogy of Fallot with absent pulmonary valve syndrome; (2) tetralogy of Fallot with common atrioventricular (AV) canal; (3) tetralogy of Fallot with pulmonary atresia; and (4) tetralogy of Fallot with pulmonary stenosis.

What are the 4 pathologies of tetralogy of Fallot?

Tetralogy of Fallot is a combination of four congenital heart defects. The four defects are a ventricular septal defect (VSD), pulmonary stenosis, a misplaced aorta and a thickened right ventricular wall (right ventricular hypertrophy).

What causes a Tet spell?

Tet Spells happen when blood flow to the lungs is decreased. Less blood to the lungs means that less oxygen is getting picked up in the blood. Blood with lots of oxygen is bright red, while blood with less oxygen is darker, and bluish in colour. The blood with less oxygen causes the skin to have a blue tinge to it.

What are the four components of tetralogy of Fallot?

Tetralogy of Fallot is a complex heart disease with four components: pulmonic stenosis, ventricular septal defect, right ventricular concentric hypertrophy, and dextropositioned (overriding) aorta. Right-to-left shunting across the ventricular septal defect may result in generalized cyanosis and polycythemia.

What are the 4 defects in the tetralogy of Fallot?

Narrowing (stenosis) of the pulmonary artery. The pulmonary artery carries blood from the heart to the lungs for oxygen.

Why it is called Tetralogy of Fallot?

Tetralogy refers to a group of four. As four heart defects occur together from birth, it is called tetralogy. The word Fallot refers to the French physician, Etienne-Louis Arthur Fallot, who described this cardiac anomaly. Defects in tetralogy of Fallot: In Tetralogy of Fallot, the child is born with the following four heart defects:

How is VSD different from the tetralogy of Fallot?

Tetralogy of Fallot. View PDF external link opens in a new window Intensity of murmur depends on size of VSD and flow across the VSD. A small VSD has a louder murmur because the gradient between the right and left ventricles is higher. A large VSD has a soft murmur because pressures are equalised between the right and left ventricles.
