Mitral Valvuloplasty



Mitral valvuloplasty is a procedure which is done to correct mitral valve stenosis. Mitral valve stenosis is a condition in which there is narrowing of the orifice of the mitral valves of the heart. In this condition, mitral valve, which regulates blood flow on the left side of the heart, fails to open as wide as it should. It causes the left atrium to work harder to pump blood through the narrowed valve which ultimately leads to heart failure and complications such as stroke, heart rhythm problems etc.

Why it’s done

  • It is the preferred treatment for mitral valve stenosis. It is usually recommended when you have moderate to severe stenosis and if most of your mitral valve is in normal shape.
  • If you have pulmonary hypertension. It is a type of blood pressure that affects the arteries in the lungs and the right side of the heart.
  • If mitral valves are in fairy good conditions, it is an option.
  • It is recommended for older patients who have aortic valve stenosis but are not able to undergo surgery as their health do not permit them.
  • It is for some patients with pulmonary valve stenosis.

What to expect before the procedure?

  • You will be examined with the help of blood tests, chest X-ray, electrocardiogram, echocardiogram. They are usually scheduled before the day of the procedure.
  • You should take the advice of your doctor about the medication that is needed on the day of the tests.
  • You should not drink or eat at least 12 hours before this procedure.
  • Allergies should be communicated, if any.


  • It is a minimally invasive procedure which is done under the influence of anesthesia.
  • In this procedure, long and thin tubes known as catheters are first placed into blood vessels in the groin and guided into the chambers of the heart.
  • A tiny hole is created in the wall between the upper two chambers of the heart which provides an opening for the cardiologists to use left atrium with a special catheter that has a balloon at the tip.
  • It is positioned so the balloon tip is directly inside the narrowed valve. It is inflated and deflated repeatedly to widen the opening of the mitral valve.
  • The balloon is deflated and removed once the opening of the valve has widened enough.
  • The procedure lasts about 1 hour and you have to spend the night in the hospital after the procedure.




1. What steps to take just before the procedure?

You will be required to fast for 6 hours prior to the procedure. It is asked to not wear nail polish.

2. How well does it work?

The percentage of success is about 80 – 95 percent. The relief that is provided with this procedure is almost immediate.

3. What are the risks involved?

After 3-7 years, 35-50 people out of 100 need another procedure or surgery. When the procedure is completed, mitral valve regurgitation might happen in 2-10 people out of 100. In this condition, the blood leaks backward in the heart.

4. What is the time required to complete this procedure?

It takes approximately 1 hour to complete.
