What is the function of mitral valve?

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.
Prevents backflow. It prevents blood from going backwards from the left ventricle to the left atrium with each beat of the heart.

What is the function of the mitral valve in a newborn?

Same as adult. Any valve (heart, vein) prevents blood from flowing in the wrong direction. So when you heart muscle contracts, the blood can only move forward if the valve is not leaking. Age has nothing to do with it. Read more...
Pumping blood. The heart is a pump, it is made up of four chambers. The mitral valve is located on the left side of the heart between the left atrium (left top chamber) and left ventricle (left lower). For the heart to pump effectively, the valve open to move the blood from the top chamber to the lower chamber, then it closes when the ventricle contract and send the blood to the body. Abn when it leaks or tight. Read more...

No. No nuclear stress tests look at blood flow to your heart. They do not show detailed anatomy of the Heart, especially the valves. If you are concerned about Mitral valve function, either have an echo done or CT angiography with attention to the valve function. . 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...
