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. [3]
Mutations in the gene for one of the notch ligands, Jagged1, are identified in the majority of examined cases of arteriohepatic dysplasia (Alagille syndrome), characterized by defects of the great vessels (pulmonary artery stenosis), heart (tetralogy of Fallot in 13% of cases), liver, eyes, face, and
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 ...
Congenital heart problems e.g. pulmonary artery stenosis (common), Tetralogy of Fallot, overriding aorta, ventricular septal defect; and right ventricular hypertrophy. Liver (jaundice, pruritus, hepatosplenomegaly, acholia, xanthoma) Andersen–Tawil syndrome: This condition affects the QT interval (in blue) Antley–Bixler syndrome: Barth syndrome
English: What is Tetralogy of Fallot? Tetralogy of Fallot (TOF) is a congenital heart condition characterized by four heart abnormalities—stenosis in the right ventricular outflow tract, right ventricular hypertrophy, ventricular septal defect, and aortic override of septal defect. Together, these can cause cyanosis in the newborn.
In tetralogy of Fallot, episodes in which infants become cyanotic are called tet spells, typically occurring during feeding or crying. [18] When older, children may squat to feel relief since this increases the systemic vascular resistance causing more blood to go towards the lungs, resulting in increased oxygenation. [18]
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.
