A Simple Explanation

This is a Procedure to open up the narrowed Mitral valve using a catheter with a balloon at its tip.

What is Balloon Mitral Valvotomy?

Balloon Mitral Valvotomy is used to treat patients suffering from a stenotic Mitral valve, by dilating it using a balloon. This is a minimal invasive procedure where the doctor inserts a catheter (thin flexible tube) with a special balloon through an artery in the groin or arm and guided to the chambers of the heart. Then a small hole is created in the wall between the upper two chambers of the heart. The catheter with the balloon is then pushed through this hole.

The catheter is then positioned in such a way that the balloon tip is inside the narrowed valve. The balloon is inflated and deflated couple of times to widen the valve opening. Once the opening in the valve is wide enough, as per the operating doctor, the balloon is deflated and removed.

The doctor usually will perform an Echocardiogram to get a better picture of the mitral valve.

What is Mitral Stenosis?

This is the condition of narrowing of the mitral valve. Mitral valve is the valve between the Left Atrium and the Left Ventricle heart chambers. This narrowing in turn hampers the flow of blood from the left atrium to the left ventricle.

Mistral Stenosis usually develops in a patient who had rheumatic fever, after a long time.


The common symptoms found in patients with Mitral Stenosis are:

  • Shortness of breath
  • Fatigue
  • Rapid weight gain
  • Weakness
  • Dizziness
  • Swelling in the ankles, feet and abdomen
  • Heart Palpitations

The procedure might last for a couple of hours to several hours; this includes the actual procedure, the preparation of the patient and also the recovery time.

Patient’s Role


  • The patient will have to take blood tests, Chest X-Ray, Electrocardiogram and an Echocardiogram
  • Please inquire with the doctor about the medications to be taken on the day of the procedure. Especially for,
    • Diabetic patients
    • Patients using blood thinning medications
  • The patient will have to refrain from consuming any food or water a couple of hours before the procedure, which the doctor will inform.
  • Please inform the doctor about any allergies, that you might have.


Please always inform the doctor if any of the symptoms return and so that the doctor can take measures to rectify them. There is a chance of any of the following complications to occur after the procedure has been performed:

  • Mitral Valve Regurgitation. This happens as a rare occurrence for some patients where the valve might be damaged prior to the procedure and it might not close normally and blood starts to leak backwards to the heart.
  • Restenosis. The valve might start to narrow again, if that is the case, valve replacement surgery is another option.
