Tetralogy of Fallot (TOF), formerly known as Steno-Fallot tetralogy, [9] is a congenital heart defect characterized by four specific cardiac defects. [4] Classically, the four defects are: [ 4 ] pulmonary stenosis , which is narrowing of the exit from the right ventricle;
The Blalock–Thomas–Taussig shunt (BTT shunt), [1] previously known as the Blalock–Taussig Shunt (BT shunt), [2] is a surgical procedure used to increase blood flow to the lungs in some forms of congenital heart disease [3] such as pulmonary atresia and tetralogy of Fallot, which are common causes of blue baby syndrome.

4 Tetra- prefix: Tetralogy of Fallot; 5 Words: Total anomalous pulmonary venous return; A mainstem intubation with an endotracheal tube can lead to right-to-left shunting. [citation needed] This occurs when the tip of the endotracheal tube is placed beyond the carina. In this way only one lung is oxygenated and oxygen-poor blood from the non ...
The collaterals continue to grow, and can become the main supply of blood to the lungs. Though it is usually associated with congenital heart diseases with decreased pulmonary blood flow, like tetralogy of Fallot or pulmonary atresia, it may be seen sometimes in isolation (i.e. not associated with any congenital heart disease).
Tetralogy of Fallot is actually the most common cause of cyanotic congenital heart defects, accounting for about 50-70%, as well as about 10% of all congenital heart defects in general. Now, it’s not quite clear why some babies develop TOF but it is associated with chromosome 22 deletions and DiGeorge syndrome.
She had a condition called Tetralogy of Fallot, one of the primary congenital defects that lead to blue baby syndrome. In this condition, defects in the great vessels and wall of the heart lead to a chronic lack of oxygen in the blood. In Eileen's case, this made her lips and fingers turn blue, with the rest of her skin having a very faint blue ...
Surgical mortality for uncomplicated ostium primum defects in experienced centers is 2%; for uncomplicated cases of complete atrioventricular canal defect, 4% or less. Certain complications such as tetralogy of Fallot or highly unbalanced flow across the common AV valve can increase risk significantly. [13] [14]
