What is cyanotic congenital heart disease?
Cyanotic congenital heart disease: Cyanotic congenital heart disease (CCHD) involves heart defects that reduce the amount of oxygen delivered to the rest of your body. It’s sometimes called critical congenital heart disease. When a baby is born with CCHD, their skin has a bluish tint, called cyanosis.
What is isolated CHD?
The majority of patients with CHD have an isolated heart defect without other organ system involvement, but the genetic basis of isolated CHD has been even more difficult to elucidate compared to syndromic CHD.
What is the most common cyanotic congenital heart disease?
Tetralogy of Fallot (ToF) ToF is the most common cyanotic heart defect, but may not always become apparent immediately after birth. There are many different variation of tetralogy of Fallot. Those babies with tetralogy of Fallot and pulmonary atresia tend to be more cyanotic in the immediate newborn period.
What is the meaning of cyanotic?
Definition of cyanotic : marked by or causing a bluish or purplish discoloration (as of the skin and mucous membranes) due to deficient oxygenation of the blood : relating to or affected with cyanosis On arrival at the emergency room, the patient was cyanotic and unconscious with labored respirations at 40/min.—
What is cyanotic and Acyanotic heart disease?
Cyanotic congenital heart disease: Cyanotic heart disease involves heart defects that reduce the amount of oxygen delivered to the rest of the body. Acyanotic congenital heart disease: With this type of heart defect, blood contains enough oxygen, but it’s pumped throughout the body abnormally.
What gene is responsible for congenital heart disease?
Initially, mutations in PTPN11, a gene involved in Ras signaling, were identified to be the cause of 50% of cases [16]. Subsequent studies have found that mutations of other genes involved in the Ras signaling pathway including RAF1, SOS1, and KRAS were also associated with a similar spectrum of disease [17-20].
What gene causes congenital heart disease?
Previous research found that chromosomal aneuploidy is a genetic cause of syndromic CHD responsible for a large proportion of CHD (46). The most common chromosomal aneuploidy causing CHD is Down syndrome due to trisomy of chromosome 21 and partial trisomy 21 (i.e., translocation, mosaicism) (46).
How common is cyanotic heart disease?
Congenital heart disease (CHD) affects 8 to 9 per 1000 live births, and approximately 25% are considered CCHD. The incidence of CHD increase to 2% to 6% for a second pregnancy after the birth of a child with CHD or if a parent is affected. Tetralogy of Fallot (TOF) is the most common CCHD (5% of all CCHD).
What cyanotic means?
What is cyanotic site?
The prime sites of the bluish discoloration in central cyanosis are lips, tongue, hands, feet, and mucous membranes of the oral cavity. The depth of the color usually correlates with the amount of desaturated hemoglobin, and hence, the severity of cyanosis.
What is the difference between cyanotic and acyanotic congenital heart defects?
There are many types of congenital heart defects. If the defect lowers the amount of oxygen in the body, it is called cyanotic. If the defect doesn’t affect oxygen in the body, it is called acyanotic.
What causes congenital heart disease in newborns?
Some babies have heart defects because of changes in their individual genes or chromosomes. CHDs also are thought to be caused by a combination of genes and other factors, such as things in the environment, the mother’s diet, the mother’s health conditions, or the mother’s medication use during pregnancy.
How do you manage cyanosis?
Treatment of cyanosis
- Warming of the affected areas.
- Surgery as a treatment for cyanosis.
- Oxygenation as a treatment for cyanosis.
- Intravenous fluids.
- Drugs as a treatment for cyanosis.
- Immunizations for children with cyanosis.
- Injections for babies with cyanosis.
- Glucose administration.
How many types of cyanotic heart disease are there?
CHD is often divided into two types: cyanotic (blue skin color caused by a lack of oxygen) and non-cyanotic.
What are the types of congenital heart disease?
Congenital heart disease refers to a range of possible heart defects.
- Aortic valve stenosis. Aortic valve stenosis is a serious type of congenital heart defect.
- Coarctation of the aorta.
- Ebstein’s anomaly.
- Patent ductus arteriosus.
- Pulmonary valve stenosis.
- Septal defects.
- Single ventricle defects.
- Tetralogy of Fallot.

What increases the risk of cyanotic heart disease in infants?
Certain medical conditions in the mother can increase the risk of certain cyanotic heart diseases in the infant. Some examples include: Genetic and chromosomal syndromes, such as Down syndrome, trisomy 13, Turner syndrome, Marfan syndrome, and Noonan syndrome
What are the complications of cyanotic heart disease?
Complications of cyanotic heart disease include: Abnormal heart rhythms and sudden death Long-term (chronic) high blood pressure in the blood vessels of the lung Heart failure Infection in the heart Stroke Death
