What is the difference between mitral regurgitation and mitral stenosis?

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. ...Read more

Mitral Regurgitation (Definition)

Mitral regurgitation or mitral insufficiency or mitral incompetence is a disorder of the heart in which the mitral valve, separating left atrium and left ventricle does not close properly. When the heart pumps out blood from the left atrium to the left ventricle through the incompetent valve, it leads to the abnormal leaking of blood from the left ventricle back ...Read more

Are mitral regurgitation and mitral stenosis the same?

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?

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

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?

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

Mitral Stenosis (Definition)

Mitral stenosis is a narrowing and stiffening of the heart valve separating the top and bottom chambers of the left side of the heart. This narrowing makes it more difficult for blood from the top chamber of the heart to flow to the bottom chamber. Many cases of mitral stenosis are caused by a prior ...Read more

A stricture is an anatomic narrowing of any structure in the body with a lumen. Depending on the organ, the underlying causes can be traumatic, ...Read more
