Birth defect.... Congenital Heart
Posted in 2015

According to the American Heart Association, about 9 of every 1,000 babies born in the U.S. have a congenital heart defect. This is a problem that occurs as the baby's heart is developing during pregnancy, before the baby is born. Congenital heart defects are the most common birth defects.
A baby's heart starts to develop at conception, but is completely formed by 8 weeks into the pregnancy. Congenital heart defects happen during this important first 8 weeks of the baby's development. Specific steps must take place for the heart to form correctly. Often, congenital heart defects are a result of one of these steps not happening at the right time. For example, a hole is left where a dividing wall should have formed, or a single blood vessel is left, where 2 should have been.
Experts classify congenital heart defects into several categories to better understand the problems the baby will experience. They include:
  • Problems that cause too much blood to pass through the lungs. These defects allow oxygen-rich blood that should be traveling to the body to recirculate through the lungs, causing increased pressure and stress in the lungs.
  • Problems that cause too little blood to pass through the lungs. These defects allow blood that has not been to the lungs to pick up oxygen (and, therefore, is oxygen-poor) to travel to the body. The body does not get enough oxygen with these heart problems, and the baby may be cyanotic, or have a blue coloring.
  • Problems that cause too little blood to travel to the body. These defects are a result of underdeveloped chambers of the heart or blockages in blood vessels that prevent the proper amount of blood from traveling to the body to meet its needs.
My advise
1....   Patent ductus arteriosus (PDA). This defect occurs when the normal closure of the ductus arteriosus, which is present in all fetuses, does not occur. Extra blood goes from the aorta into the lungs and may lead to "flooding" of the lungs, rapid breathing, and poor weight gain. PDA is often seen in premature infants.
2..... Atrial septal defect (ASD). In this condition, there is a hole between the 2 upper chambers of the heart—the right and left atria. This causes an abnormal blood flow through the heart. Some children may have no symptoms and appear healthy. However, if the ASD is large, permitting a large amount of blood to pass to the right side, symptoms will be noted.
3...   Ventricular septal defect (VSD). In this condition, a hole in the ventricular septum (a dividing wall between the 2 lower chambers of the heart— the right and left ventricles) occurs. Because of this opening, blood from the left ventricle flows back into the right ventricle, due to higher pressure in the left ventricle. This causes an extra volume of blood to be pumped into the lungs by the right ventricle, which can create congestion in the lungs.
4....  Atrioventricular canal (AVC or AV canal). AVC is a heart problem that involves several abnormalities of structures inside the heart. These include atrial septal defect, ventricular septal defect, and improperly formed mitral and/or tricuspid valves.
5....  Some of the problems that cause too little blood to pass through the lungs include the following:
a...... Tricuspid atresia. In this condition, the tricuspid valve does not form. Therefore, no blood flows from the right atrium to the right ventricle. Tricuspid atresia is characterized by the following:  1... A small right ventricle 2..Poor blood flow to the lungs  and 3.. A bluish color of the skin and mucous membranes caused from a lack of oxygen (cyanosis)
b....  A series of surgical procedures are often needed to increase the blood flow to the lungs and establish separate circulations.
6..... I advise every couple to follow healthy habits so that proper oxygen is supplied to the heart of the child.
7..    Mother should not take any incident seriously which may cause her heart function abnormally which results the child will not receive sufficient oxygen to open all cells of his heart.
8...   Mother should be happy till the delivery
