What is mitral stenosis of the heart?
Mitral valve stenosis — sometimes called mitral stenosis — is a narrowing of the heart’s mitral valve. This abnormal valve doesn’t open properly, blocking blood flow into the main pumping chamber of your heart (left ventricle). Mitral valve stenosis can make you tired and short of breath, among other problems.
What is the most common cause of mitral stenosis?
The most common cause of mitral valve stenosis is rheumatic fever — a complication of strep throat. This infection can scar the mitral valve, causing it to narrow.
Is mitral stenosis a heart disease?
Mitral valve stenosis, a form of valvular heart disease, is characterized by the narrowing of the opening in the mitral valve, which lies between the left atrium and the left ventricle in the heart. This narrowing can reduce the amount of blood the heart can pump, leaving you tired and often short of breath.
How do you rule out mitral stenosis?
Common tests to diagnose mitral valve stenosis include:
- Electrocardiogram (ECG). Wires (electrodes) attached to pads on your skin measure electrical signals from your heart, providing information about your heart rhythm.
- Chest X-ray.
- Transthoracic echocardiogram.
- Transesophageal echocardiogram.
- Cardiac catheterization.
Is mitral stenosis hereditary?
Mitral valve prolapse is an inherited autosomal dominant condition irrespective of clinical findings, and the mitral prolapse gene shows age and sex dependent expression. Mitral valve prolapse appears to be the commonest mendelian cardiovascular abnormality in humans.
What causes narrowing of heart valve?
In most elderly adults, aortic stenosis is caused by a build-up of calcium (a mineral found in your blood) on the valve leaflets. Over time, this causes the leaflets to become stiff, reducing their ability to fully open and close.
What is the life expectancy of mitral stenosis?
Depends: Mitral stenosis caused by previous rheumatic fever typically continues to slowly worsen over time. Left untreated this is very serious and life threatening. It may 10-20 yrs or more to worsen to point of being a concern. Surgical treatment of mitral stenosis is available and effective.
What are the causes and treatment of mitral stenosis?
Mitral Valve Stenosis: Causes, Symptoms & Treatment Causes of Mitral Valve Stenosis. Rheumatic fever: Rheumatic fever, a complication of strep throat or scarlet fever, is the most common cause of mitral valve stenosis. Signs & Symptoms of Mitral Valve Stenosis. The symptoms of mitral valve stenosis depend on the stage of the disease. Treatment of Mitral Valve Stenosis.
What are the cardinal signs of mitral stenosis?
Normal or low volume pulse : Atrial fibrillation may be present.
How is mitral insufficiency diagnosed?
When the doctor listens to the heart sounds, mitral valve insufficiency is generally recognized by the sound the blood makes as it leaks backward. It sounds like a regurgitant murmur. The next step is generally a chest x ray and an electrocardiogram (ECG) to see if the heart is enlarged.
