- Mitral valve stenosis – or mitral stenosis – is a narrowing of the mitral valve of the heart. This abnormal valve does not open properly and blocks blood flow to the main pumping chamber of your heart (left ventricle). Mitral valve stenosis can lead to tiredness and shortness of breath, among other things. Stenosis, mitral valve treatment in hyderabad
You may feel fine with mitral valve stenosis or have minimal symptoms for decades. Mitral valve stenosis usually progresses slowly over time. Ask your doctor if you develop:
- Shortness of breath, especially when you are exerting yourself or when you lie down
- Fatigue, especially with increased physical activity
- Swollen feet or legs
- Palpitations – sensations of a fast, floating heartbeat
- Dizziness or fainting
- Cough blood
Causes of mitral valve stenosis are:
Acute joint rhumatism. As a complication of strep throat, rheumatic fever can damage the mitral valve. Rheumatic fever is the most common cause of mitral valve stenosis. This can damage the mitral valve by causing the lobes to thicken or fuse together. The signs and symptoms of mitral valve stenosis may not show up for years.
Calcium deposits. With age, calcium deposits can build up around the annulus around the mitral valve, which can occasionally cause mitral valve stenosis.
Mitral valve stenosis is rarer now than it used to be as the most common cause, rheumatic fever, is rare in the United States. However, rheumatic fever remains a problem in developing countries Stenosis, mitral valve treatment in hyderabad
Risk factors for mitral valve stenosis are:
- History of rheumatic fever
- Untreated strep infections
Like other heart valve problems, mitral valve stenosis can put stress on your heart and reduce blood flow. Untreated mitral valve stenosis can lead to complications such as:
Pulmonary hypertension. This is a condition characterized by increased pressure in the arteries that carry blood from your heart to your lungs (pulmonary arteries), which makes your heart work harder.
Heart failure. A narrowed mitral valve disrupts blood flow. This can put pressure in your lungs and cause fluid to build up. The build-up of fluid puts stress on the right side of the heart and leads to right heart failure.
When blood and fluid get back into your lungs, it can lead to a condition known as pulmonary edema. This can cause shortness of breath and sometimes a bloody cough. Stenosis, mitral valve treatment in hyderabad
The best way to prevent mitral valve stenosis is to prevent the most common cause, rheumatic fever. You can do this by making sure you and your children see your doctor about a sore throat. Untreated strep infections can lead to rheumatic fever. Fortunately, strep throat can usually be easily treated with antibiotics.
