Cyanotic Congenital Disease (CCHD)

Cyanotic Congenital Disease (CCHD)
Cyanotic Congenital Disease (CCHD) refers to a group of many different heart defects that result in a low blood oxygen level. Cyanosis refers to a bluish colour of the skin and mucous membranes. This often occurs in the lips, toes, or fingers.

Another common symptom is difficulty breathing, especially after physical activity. Additionally, some children experience spells during which their oxygen levels are very low. As a result, they get anxious, which results blue skin, and may hyperventilate.

In many cases, an infant will be born with this disease in association with a genetic factor. An infant is more at risk for CCHD when there’s a family history of congenital heart diseases. Certain genetic syndromes can be accompanied by defects that cause CCHD, such as down syndrome. Although, in some instances, external factors can cause this disease, particularly if a pregnant woman is exposed to toxic chemicals or certain drugs, it can negatively affect her infant heart development. Infections during pregnancy are also a factor. Poorly controlled gestational diabetes can also lead to a higher risk of the infant developing CCHD.
