Mitral Valve Prolapse Syndrome- Mvp

Mitral valve prolapse syndrome is a medical term describing an abnormal movement of the mitral valve as the heart beats.

Mitral valve prolapse is a medical term describing an abnormal movement of the mitral valve as the heart beats. It is frequently abbreviated as MVP.

In order to understand this condition a brief description of the heart, its structure and function, what the mitral valve is and the role it plays in the circulatory system is necessary.

The heart is made of four chambers the right and left atria and the right and left ventricles. The ventricles are the lower chambers the atria are the upper chambers. Each atrium and ventricle combination form a pump. The atrium where blood enters the heart is a collecting camber. It then pumps into the ventricle and out of the heart. Newly oxygenated blood returns to the left atrium, the top and left side of the heart. It is ten pumped through the mitral valve into the left ventricle. It then is pumped throughout the body to nourish the body's cells. Blood is so vital as it transports oxygen nutrients and removes waste products. The entire circulatory system takes sixty seconds and will continue your entire lifetime.



It is critical that blood flows in the correct direction from the chambers by contractions. The valves protect the heart from an incorrect flow. They are flaps that separate each chamber. At the appropriate time they open to allow blood to flow through, and close to prevent the blood form following backwards. The mitral valve allows blood to flow from the left atrium into the left ventricle.

The valve should open to allow a free flow of blood from the atria and then close tightly to prevent any blood from flowing back into the atria when the ventricles contract.

The mitral valve is the most vulnerable to damage. It has two leaflets. If one or both leaflets are damaged the leaflet may be unable to close tightly to prevent back flow. If the valve is unable to close properly or seal tightly some of the blood that has been pumped can leak backwards. This is called regurgitation. This backward flow of blood can cause the heart to work harder and can lead to heart damage.

One or both of the mitral leaflets may not close tightly or fit properly. One or both can bend or snap back the atrium during a ventricle contraction.

The term prolapse is used for this flap or snap back into the left atria. Prolapse comes from this action and means to billon.

The cause for the defect is generally in the structure of the valves connective tissue. This tissue is actually the backbone of the valve. If these tissue problems are present the leaflets may become stretched out of shape or became longer. One or both leaflets can be affected. The elongation and loss of shingth cause the valve to bellow of flaps backwards. Incorrect movement may also be related to the shape of the mitral valve, the little tendons or the codae which normally hold the valve in place.

These structural problems may be genetically transmitted, a result of congenital birth defect, some other medical condition or for no known reason.
