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.

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 ...
The most typical form of APVS is a tetralogy of Fallot variant, [4] however, case studies have linked APVS to several different congenital cardiac syndromes, such as agenesis of ductus arteriosus, [5] persistent ductus arteriosus, [6] atrioventricular septal defect, [7] pulmonary branching abnormalities, [8] [9] transposition of the great arteries, [10] and type B interrupted aortic arch. [11]
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.
Tetralogy of Fallot: pulmonary stenosis, ventricular septal defect, right ventricular hypertrophy, overriding aorta: Tetralogy of Fallot Ménière's disease: vertigo, tinnitus, fluctuating low frequency hearing loss, aural fullness: Ménière's disease zoonotic tetrad: scrub typhus, chiggers, rodents and birds, scrub vegetation
Trilogy of Fallot is a combination of three congenital heart defects: pulmonary stenosis, right ventricular hypertrophy, and an atrial septal defect. [ 1 ] The first two of these are also found in the more common tetralogy of Fallot .
Ebstein's anomaly is a congenital heart defect in which the septal and posterior leaflets of the tricuspid valve are displaced downwards towards the apex of the right ventricle of the heart. [1]
