What is interventricular septum?

interventricular septum or ventricular septum indicates an important dividing wall in the heart. This wall separates the chambers, which are the lower two heart chambers and the main pumping chambers of the heart. In most cases, it is exceptionally important that a complete separation is achieved and each chamber works without any kind of blood communication with another. The interventricular septum will achieve this, except when there are defects or affect a certain heart disease.

In the normal heart, the right ventricles are divided from the left ventricle by a septum. Among the hall is open small communication called foramen ovale, and this usually closes in the first year of life. Similar opening should not exist in interventricular septum. When it is created in the first few months of life, the wall or septum should be closed.

As interventricular septum develops, it actually has two discrete portions, although the wall only permeable. The upper part is called a membrane or perimembrank and the lower part is called withrolledá. Sometimes, when the heart is formed, there is an error in the construction of a septal wall and instead of the desired closure between the right and left ventricles there is a communication between the two chambers through openings. Most often they occur in the perimembranská part, but about a quarter of them can also be represented in the muscle interventricular part of the septum. Both are called defects of ventricular septum or VSD.

While some VSD types are small and do not require medical intervention, large holes or more holes in the interventricular septum can be extremely problematic. One of the problems may have caused blood from the left ventricle that is about to draw into the body, penetrate the right ventricle, and this can increase lung pressure and ultimators cause problems such as heart failure. Large VSD is usually relatively easy to diagnose from recognizable heart mumming, but small can be harder to catch.

Surprisingly, sometimes interventricular septum actually disrupts the function of the heart if the heart has several significant defects. If there are errors with heart valves, very small chambers or other problems, large VSD may allow the necessary blood mixing and can actually help survival until surgery is performed. Whether VSD is closed during surgery or not depends on the type of surgery and the ability to repair all defects.

Another problem may occur in interventricular septum and it has nothing to do with birth with innate defects. Although rare, during some heart attacks the septum may be damaged or even have a hole in it. It is usually necessary to deal with this infarction of VSD as quickly as possible to restore normal heart health.
