Percutaneous Mitral and Aortic Valvuloplasty

What is Percutaneous Mitral and Aortic Valvuloplasty?

What is Mitral Stenosis?

Mitral stenosis is a blockage of the mitral valve in the heart. The two flaps of the valve (leaflets) have become stuck together, which reduces the blood flow from one heart chamber to another, causing a back-up of fluid into the lungs. This makes you feel short of breath.

What is Aortic Stenosis?

Aortic stenosis can be a problem as you get older. The aortic valve controls the amount of blood that leaves the heart to be pumped around the body. Sometimes the valve becomes narrow because of disease. This is called aortic stenosis. The blood is no longer able to flow freely from the heart and supply the body. This may result in you experiencing chest pain, shortness of breath or fainting.

Aortic Valvuloplasty is not able to get rid of all the narrowing. The procedure is done to relieve the symptoms caused by your valve disease, but it is not a long-term cure.

How to prepare for Percutaneous Mitral and Aortic Valvuloplasty procedures

You will be required to fast for 6 hours prior to the procedure (no food or drink). Your Doctor will advise if you should cease any medication. Take any medication you require in the morning with a small amount of water.

You may require some or all of the following tests prior to the procedure:

  • Echocardiography
  • Coronary Angiography
  • Right Heart Catheter – After an injection of local anaesthetic, a soft balloon catheter is put into the vein in your groin. The tube is passed along until it reaches the heart and then goes up into the blood vessels of the lung. The pressures in the lungs and heart are recorded.

What happens during Percutaneous Mitral and Aortic Valvuloplasty procedures

A valvuloplasty is a procedure where the valve is widened using a balloon. This will allow the blood to flow more freely. You will be given a local anaesthetic and sedative to help you relax.

A small incision is made in the groin area and a wire is passed along the blood vessel, up to the heart, until it reaches the aortic valve, or mitral valve, depending on where the blockage lies. The Doctor uses X-ray imaging to see the wire.

Once the wire is in place, a balloon is passed along the wire and into the damaged valve. The balloon is pumped up where the valve is narrowed. This widens the valve, as far as possible. The balloon may be pumped up several times.

At the end of the procedure, the wire and balloon are removed.


Aortic Valvuloplasty

Aortic Valvuloplasty is not able to get rid of all the narrowing. The procedure is done to relieve the symptoms caused by your valve disease, but it is not a long-term cure.

This temporary repair can last 6 to 12 months. It is likely your symptoms will return within 1 to 3 years. Depending on your illness, a repeat balloon procedure may be needed.

You will only have this procedure if you are not a suitable candidate for heart surgery.

Mitral Valvuloplasty

Mitral Valvuloplasty can give you complete relief of symptoms in over 90% of patients. This improvement can last for up to 20 years. Most patients have relief for at least 5 to 10 years.

What happens after Percutaneous Mitral and
Aortic Valvuloplasty procedures

Patients will generally be discharged from hospital the day after the procedure. Your doctor will review you prior to discharge. A QCG staff member will be in contact with you in the weeks after your procedure to arrange a follow-up appointment in the rooms with your doctor.

In recommending this procedure, your doctor has balanced the benefits and risks of performing the procedure against the benefits and risks of not proceeding. Your doctor believes there is a net benefit in going ahead.

Percutaneous Mitral And Aortic
Closure Frequently Asked Questions

“The risks and complications associated with percutaneous mitral and aortic procedures are generally low, and most patients recover well from the procedure with no complications. However, it is important to discuss any concerns or questions with your doctor before undergoing any medical procedure.

Bleeding: There is a risk of bleeding at the incision site or from blood vessels around the heart during the procedure.

Infection: As with any invasive procedure, there is a risk of infection at the site of the incision or in the heart itself.

Damage to blood vessels or organs: The catheter used in the procedure can damage blood vessels or organs, particularly if it is not inserted or guided correctly.

Arrhythmia: The heart’s rhythm may become irregular during the procedure, and patients may need medication or further procedures to correct this.

Stroke: There is a small risk of stroke associated with the procedure, particularly if small pieces of tissue or blood clots become dislodged during the procedure and travel to the brain.

Heart attack: There is a risk of heart attack during the procedure, particularly if the catheter blocks blood flow to the heart.”
