A congenital heart defect is a flow defect in blood flow through a heart. This may cause block or slow down in a blood flowing heart. This causes the abnormal flow of blood through the heart and making the heart work harder. It is an abnormal formation of the heart during growth in the womb. Abnormality in the number of baby chromosomes through the source of single gene defects from parents and also from environmental sources.

TYPES
This may vary from simple to complex forms of CHDs. They are,
- Ventricular septal defects
- Tetralogy of Fallot
- Transposition of great arteries

- Coarctation of aorta
Some of the flow defects such as Atrial & Ventricular septal defects.Blood flow from the left side to the right side such as left to right shunts.
GROUP
- Cyanotic - Bluish discoloration of lips, gums, and skin ( circulation of blood does not have enough oxygen )

- Connective tissue disorder
FAMILY HISTORY & CHDs
It is an Autosomal dominant inheritance. About 1% of all children. First-degree relatives are at a higher risk of CHDs.

CHROMOSOMAL ABNORMALITIES
In each cell body of a living being has 46 chromosomes. Having too many or too few chromosomes causes CHDs. They may also cause structural defects that are missing half several chromosomes.
