heart is the most important organ in the human body. Without the heart life would not be possible, it is responsible for getting neturients and oxygen throught the body by way of the circulatory system. Modern medicine has advanced greatly within the last 30 years and almost all heart diseases can be treated successfully if detected in time.
Congenital heart disease (CHD) is a malformation of the large blood vessel near the heart. Congenital heart disease is one of the most common forms of major birth defects in newborns, affecting approximately 8 percent of infants and is normally diagnosed within one week from birth.
Prior to birth the fetus is not effected by this birth defect. The blood circulates differently prior to birth and the fetus derives oxygen and nutrients from the mother through the placenta. The fetal circulation has important communications between the upper heart chambers and the great blood vessels near the heart. Most types of congenital heart disease are well tolerated during fetal life and only present a problem after birth.
This disease can have different causes such as:
Environmental factors such as chemicals or drugs are sometimes to blame. If the mother develops measles or rubella, or consumes alcohol during pregnancy, the disease can impair the development of the fetus heart or other organs. …show more content…
Down's Syndrome is caused by the presence of a single extra chromosome when the sperm cell and ovum join together. The general scientific option is that the extra chromosome produces extra enzymes in excessive quantity. It is believed that the excessive enzymes somehow cause them to interfere with each other and that the developing cells are inefficiently nourished and the bloodstream becomes clogged with the unused nutrients. As a result the organs and tissues do not mature properly. At birth the heart, lungs and brain are malformed and function
