What is the difference between mitral regurgitation and mitral stenosis?

Blockage vs leaking. In stenosis the valve opening is to small which interferes with forward flow. Regurgitation is a leaking of the blood backwards. Not uncommonly both occur in the same patient.
Loose vs Tight. The mitral valve directs blood flow from the left atrium to the left ventricle. When the lv squeezes the mv prevents blood from leaking back into la. If the mv fails to completely close and blood leaks back this is mitral regurgitation or insufficiency. When the mv is stiff and doesn't open enough and slows down the flow into the lv this is mitral stenosis. A mv can also have both at the same time.

Are mitral regurgitation and mitral stenosis the same?

No. Regurgitation is when the valves dont close properly and blood back flows stenosis is when the opening is narrowed making the outflow reduced. Read more...

Do you know are mitral regurgitation and mitral stenosis the same thing?

Different. The mitral valve sits between the left atrium, which receives blood from the lungs, and the left ventricle, which pumps blood to the body. Mitral regurgitation is "backleak" of blood from the left ventricle back to the left atrium. Mitral stenosis is restricted opening of the valve, partially blocking blood flowing from the atrium to the ventricle. Both can exist in the same patient. Read more...

Is mitral regurgitation the same thing as? Mitral stenosis?

Not exactly. Mitral regurgitation (mitral valve regurgitation, mitral incompetence, mitral insufficiency) is leakage of blood backward through the mitral valve each time the left ventricle contracts. Read more...
Different issues. Mitral stenosis: essentially means the valve doesn't open all the way, the valve in narrow or narrowed... Mitral regurgitation: means the valve leaks when it is closed. Read more...

Patched Vsd, aortic stenosis mitral regurgitation. Going to dentist w/ prophylaxis. 24 M. What chances do I have of getting endocarditis?

Discuss w/ dentist . This is something that you need to have your dentist and physician discuss to determine what if any precautions must be determined. In all likelihood they will recommend the use of a pre treatment antibiotic but again that must be determined by these health care professionals. Read more...

Difference between the characteristics of mitral stenosis and mitral regurgitaion?

Blocked vs Leaking. Stenosis means the valve does not open enough and restricts the flow of blood thru the valve. Regugitation means the valve leaks when closed and allows blood to flow in reverese. Both cause the hear to have to work harder. Mitral regurge is much more common than stenosis in industrialized nations because antibiotics used to treat strep infections have reduced rheumatic fever rates. Read more...

How can there be a systolic murmur in mitral stenosis without regurgitation in the mitral area?

Mitral stenosis. Aha! sophisticated question! you are correct in that mitral stenosis produces a loud s1, opening snap, followed by a diastolic rumble. It would be unusual to have the typical findings of mitral stenosis with significant mitral insufficiency. However! there can be associated abnormalities such as aortic stenosis which would produce a systolic murmur! Read more...
Pulmonary HTN. You're correct. Mitral stenosis produces a diastolic rumble or murmur. However, as mitral stenosis worsens patients develop pulmonary hypertension. This in turn will increase the pressure in the right ventricle which could induce a normal tricuspid valve to leak. This murmur would be systolic. Read more...

What are the differences between aortic stenosis and mitral regurgitation murmur?

Multiple. The pitch is different. Also, each is better heard in a different location in the chest, and the duration of the murmur during the cardiac cycle are different. Read more...
