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.
A fancy gate. This structure sits between the left atrium and left ventricle. It allows unidirectional flow from the atrium to the ventricle.

Can you tell me what is a mitral valve prolapse and what are the dangers?

Mitral valve prolaps. Mitral valve prolapse (aka primary form of myxomatous degeneration of the mitral valve aka floppy mitral valve syndrome) is a valvular heart disease characterized by the displacement of an abnormally thickened mitral valve leaflet into the left atrium during systole. Eventually it could lead to worsening of mitral regurgitation, heart failure, cardioac arrythmias and death. Read more...

What is mild mitral valve prolapse and associated moderate mitral insufficiency?

Floppy Valve Tissue. In mitral valve prolapse, the mitral valve tissue is structurally abnormal. The valve is too large for the mitral valve orifice and buckles during closure. This results in leaking of blood from the left ventricle back into the left atrium. Read more...
2 different things. Mitral valve prolapse is a description of how the valve closes. It may or may not leak mild is an attempt to classify the severity the prolapse. Mitral regurge is when blood flows backwards thru a closed mitral valve (it leaks). This is classified as trace, mild, moderate, moderate severe , and severe. Read more...
Sometimes Related. Mitral valve prolapse is a common, typically mild condition in which one or both of the valve leaflets bulge backwards during valve closure. Mitral insufficiency is abnormal, backward leakage through the closed valve. If mild, negative effects are unusual. If severe, it can cause congestive failure, rhythm disturbances and other unwanted effects. Mvp, is one of many causes of insufficiency. Read more...

What's the mitral valve's purpose?

Backflow. The mv prevents blood from backing up into the lungs during left ventricular contraction. 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...
