What is Tet spell in tetralogy of Fallot?
Infants with tetralogy of Fallot can have a bluish-looking skin color―called cyanosis―because their blood doesn’t carry enough oxygen. At birth, infants might not have blue-looking skin, but later might develop sudden episodes of bluish skin during crying or feeding. These episodes are called tet spells.
What are the 4 abnormalities in tetralogy of Fallot?
The four defects are a ventricular septal defect (VSD), pulmonary stenosis, a misplaced aorta and a thickened right ventricular wall (right ventricular hypertrophy). They usually result in a lack of oxygen-rich blood reaching the body.
What causes murmur in tetralogy of Fallot?
The murmur in tetralogy is due to the pulmonic stenosis. Most cases are congenital… read more ; the ventricular septal defect is usually silent because it is large and has no pressure gradient. The 2nd heart sound (S2) is usually single because the pulmonary component is markedly reduced.
How is tetralogy of Fallot correction?

What is anoxic spell?
1 : of, relating to, or affected with anoxia. 2 : greatly deficient in oxygen : oxygenless anoxic water.
What causes Hypercyanotic spells?
Hypercyanotic spells are sudden episodes of profound cyanosis and hypoxia that may be triggered by a fall in oxygen saturation (eg, during crying, defecating), decreased systemic vascular resistance (eg, during playing, kicking legs), or sudden tachycardia or hypovolemia.
What is the ICD 10 code for tetralogy of Fallot?
2022 ICD-10-CM Diagnosis Code Q21. 3: Tetralogy of Fallot.

How do you treat cyanotic spell?
Management
- Knee to chest position.
- High flow oxygen via mask or headbox.
- Avoid exacerbating distress.
- Morphine 0.2 mg/kg IM.
- Continuous ECG and oxygen saturation monitoring, frequent BP.
- Correct any underlying cause/secondary problems, which may exacerbate episode, eg cardiac arrhythmia, hypothermia, hypoglycaemia.
What are tet spells in tetralogy of Fallot?
Tet spells. Children with tetralogy of Fallot may develop “tet spells”. These are acute hypoxia spells, characterized by shortness of breath, cyanosis, agitation, and loss of consciousness.
Is tetralogy of Fallot a critical congenital heart defect?
The muscular wall of the lower right chamber of the heart (right ventricle) is thicker than normal. This also is called ventricular hypertrophy. Because a baby with tetralogy of Fallot may need surgery or other procedures soon after birth, this birth defect is considered a critical congenital heart defect.
What causes tetralogy of Fallot?
Heart defects such as tetralogy of Fallot also are thought to be caused by a combination of genes and other risk factors, such as the things the mother or fetus come in contact with in the environment or what the mother eats or drinks or the medicines she uses. Tetralogy of Fallot may be diagnosed during pregnancy or soon after a baby is born.
What is a tet spell in babies?
Tet spells. Sometimes, babies who have tetralogy of Fallot will suddenly develop deep blue skin, nails and lips after crying or feeding, or when agitated. These episodes are called tet spells and are caused by a rapid drop in the amount of oxygen in the blood.
