What is a lesion on the mitral valve called?

Vegetation . There are many types of lesions affecting the mitral valve but the question suggests you are asking about a vegetation protruding from the edge of the valve leaflet typically caused by bacterial infection like bacterial endocarditis.
Vegetation. Most lesions on the mitral valve are referred to as vegetations. This represents a localized area of infection which constitutes the diagnosis of endocarditis. Not all lesions on the mitral valve for vegetations. Other potential lesions include marantic endocarditis (not infectious) and fibroelastoma (benign tumor).

Echocardiogram. Trivial mitral valve insufficiency is a common, insignificant finding on echocardiograms in healthy people and is ignored as a cause of symptoms including dysautonomia. Mitral valve prolapse, while often without symptoms, may cause disorders of heart rhythm. If your echo showed mvp you may be having palpitations from it. Your physician would know best as he/she examined you and has the test results. Read more...

Mitral valve. The mitral valve has to open properly to let blood flow into the left ventricle from the atrium. If it doesn't, we call this stenosis. It has to close to keep the blood flowing toward the body, if it doesn't we call this regurgitation or insufficiency. Either or both problems can exist with the valve if its abnormal. Insufficiency is more common. Read more...

What is the significance of an obstructive lesion in the mitral valve?

Slow flow. Mitral stenosis, a narrowing of the mitral valve, stresses the heart making it have to work harder to pump the blood forward. If severe enough, the output of the heart may drop and cause symptoms such as fatigue or shortness of breath. Fortunately, rheumatic fever is now rare in the U.S. So we see much less mitral stenosis. Surgery can correct the problem. Read more...

What is a mitral valve?

One of 4 heart valve. The mitral valve is one of the 4 heart valves found in the heart. These valves keep blood moving one direction rather than back and forth as the heart contracts. The mitral valve is so named as it looks like the pope's hat (a mitre). The mitral valve separates the left atrium and the left ventricle. Read more...

The heart is a pump. Moving blood by squeezing. The valves keep blood moving in the proper direction. The mitral valve prevents blood from moving backwards from the left ventricular to left atrium. Also the way the leaflets are positioned it directs blood into the lv in the most efficient direction so it can exit thru the aortic valve with the least amount of effort. That's 1 reason repair is better than replacement. Read more...

How can the mitral valve be replaced?

Many options. Depending on pts age as well as the characteristics of the valve, there are many options. Mitral valve repair -using the pts own valve and perhapse a ring. Mv replacement-the whole valve is replaced by either a mechnical valve pig valve or a bioprosthetic. Another new technology involves catheter based options such as a clip. All types have pros and cons including possible Coumadin (warfarin) therapy. Read more...
