The first heart sound in severe mitral stenosis is a loud first heart sound, a diastolic rumble and an opening snap.

And because of a wide closing excursion of the mitral leaflets the first heart sound is accentuated.

The first symptom of mitral stenosis is shortness of breath and tiredness or fatigue.

Other symptoms of mitral stenosis include chest pain, coughing up blood, dizziness and irregular heartbeats.

The best test for mitral stenosis is an echocardiogram which is useful for assessing mitral stenosis etiology, morphology, severity and treatment intervention.

The conditions that mimic mitral stenosis are left atrial myxoma, ball-valve thrombus, infective endocarditis, and cor triatriatum.

The two signs of mitral stenosis on ECG are signs of left atrial enlargement (P wave duration in lead II >0.12 seconds, P wave axis of +45 to -30 marked terminal negative component to the P wave in V1 [1 mm wide and 1 mm deep]) and, commonly, atrial fibrillation.

Mitral valve stenosis can make you tired and short of breath. Other symptoms may include irregular heartbeats, dizziness, chest pain or coughing up blood. Some people don't notice symptoms.

Mitral valve stenosis can be caused by a complication of strep throat called rheumatic fever.

The first symptom of mitral stenosis often is shortness of breath and you have have a hard time breathing, especially after you've been active or when you lay down.

You may also tire easily during increased physical activity and have swollen ankles and feet as well as heart palpitations and you may notice rapid fluttering heartbeat.

The blood pressure for mitral valve stenosis is 10 mm, higher and the diastolic level is 5 mm.

The most common cause of death in patients with mitral stenosis is congestive cardiopulmonary failure.

The medication that is used for mitral valve stenosis includes Antiarrhythmics, Calcium channel blockers, Anticoagulants, Beta-adrenergic blockers, Antibiotics, Diuretics.

Mitral valve stenosis is a disability when it prevents you from working.

However mitral valve stenosis does not automatically qualify you for disability but it can if you can demonstrate functional limitation in addition to an objective diagnosis of severity.

Mitral valve stenosis is hereditary as it can run in families.

Mitral stenosis causes shortness of breath because the valve cannot open enough and results in less blood flow through the body.

With mitral stenosis your upper heart chamber swells as pressure builds up and then the blood and fluid can collect in your lung tissue and make it hard to breathe.

Anything that can put stress on your body such as mental stress, physical stress, pregnancy, infections etc can all worsen mitral stenosis.

Mitral stenosis can also appear or become worse when your heart rate increases like during exercise or other physical activity.

Stress can cause and trigger mitral stenosis although the main risk factor of mitral stenosis is a history of rheumatic fever but even pregnancy and other conditions such as cardiac disorders, endocarditis and respiratory infection can cause mitral stenosis.

The organs that are affected by mitral stenosis is the heart and the valve between the two left heart chambers.

Mitral stenosis is narrowing of the valve that is between the two left heart chambers and when narrowed the valve reduces or even blocks blood flow into your heart's main pumping chamber.

And the heart's main pumping chamber is the lower left heart chamber that is also called the left ventricle.

Mitral stenosis causes chest by through high blood pressure being in the lung arteries.

The medical term for high blood pressure in the lung arteries is pulmonary hypertension which can occur if a narrowed mitral valve slows or blocks blood flow.

Decreased blood flow raises pressure in the lung arteries.

The heart must work harder to pump blood through the lungs.

Many people with mitral valve prolapse DO NOT have symptoms.

A group of symptoms sometimes found in people with mitral valve prolapse has been called "mitral valve prolapse syndrome," and includes: Chest pain (not caused by coronary artery disease or a heart attack) Dizziness.
