In the process of mitral valve regurgitation, regurgitation, the mitral valve which is the bicuspid valve which is present between the left atrium and the left ventricle stops working and it therefore does not close properly, does not close properly which leads to the leakage of blood, which leads to the leakage of blood back into the left atrium, back into the left atrium whereas in the tricuspid valve regurgitation, tricuspid valve regurgitation, the tricuspid valve stops functioning and it does not close properly.
01:06
So, this will lead to leaking of blood into the right atrium.
01:13
So, it leads to the leakage of blood back into the right atrium.
01:26
Now, why this is a serious problem? let us see that.
01:31
Since the mitral valve is considered more dangerous, it is because of the following reasons.
01:37
The first is blood volume and pressure.
01:44
The mitral valve is present between the left side of the heart.
01:49
So, this is responsible for pumping oxygenated blood to the body, pumping oxygenated blood to the body whereas the right side which includes the tricuspid valves pumps the deoxygenated blood to the lungs.
02:13
So, the left ventricle therefore, so the left ventricle therefore has thicker muscular wall, has a thicker more muscular wall and it generates a higher pressure, it generates a higher pressure to pump the blood throughout the body.
02:37
So, if the mitral valve regurgitation occurs, the blood leaks back into the left atrium during systole reducing the amount of blood pumping forward and potentially causing the left ventricle to work harder to maintain the cardiac output.
02:57
So, if mitral valve regurgitation happens, so if regurgitation occurs, blood leaks back to, leaks back to the left atrium thus decreasing the amount of blood pumped forward.
03:22
Therefore, the left ventricle, the left ventricle has to work harder to maintain the cardiac output, to maintain cardiac output, maintain cardiac output.

Let us look at the consequences of chronic mitral regurgitation...
