What is a mitral valve?

Mitral valve is one of the two atrioventricular valves that are located inside the heart between the atrial and the chambers. On the left side of the heart is mitral or left atrioventricular valve and on the right side there is a tricuspid valve lead between the right atrial and the right chamber. The left valve has two leaflets, unlike tricuspid, which has three that opened when the heart contraction allows you to pass blood from the left atrium to the left ventricle. In a normal heart, these leaflets are closed and close between contractions, so the passage of blood is limited.

In most cases, people will never have to think about whether they have a functional mitral valve. However, some people may be born with a number of conditions that worsen or disrupt the function of the mitral valve. Alternatively, they can obtain diseases that can affect this important pipe, and it is useful to think about its importance.

Human heart can beat about 3 billion times in a lifetime, which means that this valve must also open andClose many times. As the heart ages, the special cords that help operate the valves sometimes stretch or become less functional, which can be significant enough to cause urban heart failure. Many people never meet and should thank their hearts for their extraordinary function of such a small organic device.

Sometimes the valve at birth is functionally insufficient. Perhaps it may not be created correctly and may or may not be present with other heart defects. When people have an abnormally small left atrium or left ventricle, they may have a mitral valve that doesn't work. The valve can be called stenotic and be too small to allow sufficient blood passage from the hall to the chamber with every heartfelt. This may require surgery immediately or soon after the child is born for repairing or replication valve or stenosis can be mild and doctors can wait and see access.

isThe most common causes of mitral stenosis in the past were a contraction of rheumatic fever. Fortunately, this is rare and you do not generally see. However, it can still affect many in countries where medicine is not advanced.

Another common disorder of the mitral valve is prolapse. This occurs when the leaflets on the valve bulges into the halls while the heart is downloading. When the prolapse is present, the valve does not have to be sufficiently closed between contractions and blood can escape back from the chamber to the atrium called regurgitation. A small amount of regurgitation may not significantly affect the heart function, but massive regurgitation creates huge problems and often leads to heart failure.

Mitral valve prolapse may not cause regurgitation, and again it may be a congenital defect or such an aging or diseases such as rheumatic fever or bacterial endocarditis. It does not have to require treatment and some people do not know that they have a condition, even if it can cause some heart murmur that is quite different. PTerry is significant prolapse, some people will require surgery, which will usually mean either the replacement of the valve or attempting to repair the valve by surgical repair.

with the replacement of the valve are some problems. Tissue valves usually come from pigs or cows sources and can wear within a few years. Mechanical valves are often preferred because longer. However, most people who have mechanical valves must be at lifelong daily doses of warfarin (Coumadin®) to avoid an increased risk of stroke. Due to the problems with the replacement of the valve, surgeons often decide to repair the valve when they can prevent these problems.
