Mitral Stenosis

Mitral Valve Stenosis occurs when the valve size reduces from 4 - 6 cm2 to 2 cm2; it is severe when it is les than 1 cm2

Mitral Stenosis[MS] is the narrowing of the mitral valve causing hindrance to the blood flow. The normal mitral valve orifice is about 4 to 6 cm2. When this area becomes less than 2 cm2 , a pressure gradient across the valve develops. As the gradient increases the time for ventricles to fill increases; resulting in increased heart rate, reduced cardiac output and pulmonary hypertension. The constant increase in the left atrial pressure causes pulmonary congestion and dilates the left atrium. Patients are prone to develop atrial fibrillation and heart failure.

Mitral stenosis is termed severe when the valve area is less than 1 cm2. Mitral stenosis is more common in women than in men. Symptoms usually occur in or after the third decade of life and its progression is higher in developing countires compared to the developed western countries.

Patients undergoing mitral valve replacement are susceptible to the following risks. Bleeding, infection, complex reaction to anesthetic. The risk involved in most cases can be determined by the physician and it depends on a variety of factors such as the patient’s age, general condition, specific medical problems and heart functions.

Alternative treatment is Balloon valvuloplasty.Balloon valvuloplasty is performed using a catheter, i.e. a very thin flexible tube which can be inserted into the body, with a balloon at the end. The balloon is put inside the valve and is expanded thus stretching the valve and bringing it back to its normal size. For more info: heart-consult.com/articles.
