What are congenital heart defects?

Congate heart defects (CHDS) are the most common of all congenital defects that occur in 8 out of 1000 birth. Many CHDs are smaller, requires careful observation, but without treatment. Today, the most serious congenital heart defects can be treated and the result is quite favorable even for the most difficult defects.

congenital heart defects can be grouped as follows:

• defects affecting the development of septum, such as the defects of the chamber and septa and patent ductus, represent about 37% of all heart defects.
• flow defects that affect the chambers and/or pulmonary and aortic flaps of the heart occur in 29% of congenital presentations of heart defects. Defects of endocardial cushions such as tricuspidal atresia and complete atrioventricular channel are present in about 9% of cases.
• other forms of congenital heart defects, including dextrocardy, heterotaxia and abnormalities of coronary arteries, have 8% of the rate of occurrence.

In most CA in most Cases, there is no known reason for congenital cardiacdefects. Some mothers' behavior, such as alcohol or cocaine use, may increase the risk. Genetics can play factor in defsets such as prolapse of mitral valves and heterotaxes. Premature children have a better chance of patent ductus, in which the peak of the atrial septum does not increase properly. On the other hand, most parents with a child with congenital heart defects do not have a family history of heart defects, and defects usually cannot be associated with maternal behavior. Further research can help define causal factors.

All heart surgery to repair congenital heart defects are relatively new. At the age of 30, some defects could be repaired by closed cardiac operations. However, they were not very successful. Most defects cannot be solved until the 1950s, when Dr. Walton lillelei developed the first successful bypass on the cardiac lungs to be carried out by machine and open -heart operations.

with the development of the stroIt is on the bypass heart lungs began to treat different congenital heart defects, which increases life expectancy. The most famous of these early operations was Blalock-Taussig Shunt to treat the "blue baby syndrome", often caused by Fallota tetralogy and other defects in which neexgenated blood is sent to the body. These first operations, albeit promising, did not actually address or repair congenital heart defects. Life expectancy increased, but life expectancy was not normal, because the basic defects eventually caused heart failure. In addition, general anesthesia carried much greater risks than now.

Since these first operations were developed, significant research has been carried out to solve the specifics of different congenital heart defects. While many CHDs are now repairable, there are still some serious defects, such as hypoplastic left or right ventricle that cannot be repaired, but only alleviated before transplantation is eventually necessary.

other congenital defects have received a large number of research funds, fromAtmospheric heart research remains insufficiently financed and largely unrecognized. It is important that the most common category of congenital defects pays such little attention. Until recently, the American Association Heart Association has determined less than 10% of its income for congenital heartbeat research. Parents' lawyers and participation in local chapters American Heart Association have encouraged a greater response to the American Heart Association.

The Internet proved to be important in connecting parents with children affected by the CHD and established a strong group of advocates for further research. Parents' efforts in local communities have led to a statement of heart awareness in most US states.

Several important actors have lent their time to increase Awareness congenital heart defects and support for further CHD research. Robbie Benson, a popular teenage actor, now director and producer, has undergone a valve replacement as an adult and devoted a lot of time to raise fundsLarge research. The second daughter Jennifer Flavin and Sylvester Stallone were born with defects that required repair. In response, Flavin launched a cosmetic line on a home shopping network and devotes all profits for further awareness and research.

The outlook for repairing congenital heart defects and for normal expectations of life for children with CHD has never been better. Although research is insufficiently funded, there has been significant progress with many repairs of defects. New techniques include repairs through cardiac catheterization that can place stents or patches. Minimally invasive surgery and robotic repairs are also becoming increasingly viable. Transplant technology is also still improving and research of stem cell technology can eventually create bmability from human tissue, so rejection of transplants or lack of available hearts is no longer a factor.
