The reasons leading to congenital heart defects
To date, the scientists did not discover the causes of congenital heart defects, but there is help possible factors that help to get the deformation congenital heart when the fetus; knowing that the heart muscle is made up fully the first eight weeks of pregnancy.
Divided into two types of these reasons:
1. reasons related to the fetus.
2. For reasons of pain.
For reasons that are related to pain are:

- Where he gets when the fetus decline of ventricular fibrillation (any child that is born and has a severe lack of electrical heart) and the possible need to cultivate a battery to the heart muscle after birth.
4. Pregnant women exposed during the first trimester of pregnancy X-ray images and a private class-CT-Scan; as the ratio of harm to the fetus tenfold image of natural radiation.
5. There are other important factors can lead to distortions such as congenital heart:
A - smoking and alcohol intake.
B - having children at a later age (ie, after the age of forty).
