Percutaneous Balloon ValvuloplastyEn Español (Spanish Version)
Percutaneous balloon valvuloplasty is done to open a constricted heart valve with a balloon.

Any of the heart’s four valves can become deformed. It may happen because of conditions at birth or scarring from disease. A damaged valve can decrease the amount of blood that flows through it. This condition is called
. Low blood flow can lead to heart failure and death. The valve will need to be opened to restore full blood flow.
and congenital birth defects are two main causes of stenosis. It can also happen due to aging and calcium deposits.
Depending on the overall condition of the valve, relief of symptoms can be expected to last at least two years. Some people have relief of symptoms much longer.
If you are planning to have a valvuloplasty, your doctor will review a list of possible complications, which may include:
- Leaking valve
- Damage to the heart or other organs
- Blood clot formation
Some factors that may increase the risk of complications include:
- Blood clots in the heart
- The anatomy of the valve
- Overall health status
You will have a thorough evaluation to determine your overall condition, the health of your heart, and the exact nature of your valve defect. The success of the procedure depends a great deal on the condition of the valve. This includes whether the valve is calcified, how thick it is, and how narrow the opening is. Many valves cannot be fixed with this technique. They will require open-heart surgery instead.
Talk to your doctor about your medicines. You may be asked to stop taking some medicines up to one week before the procedure, like:
or other anti-inflammatory drugs
- Blood thinners
Only local anesthesia and, sometimes, mild sedation are used. Local anesthesia will numb the area. Sedation will help you relax.
You will be lying down in a special procedure room. There will be x-ray machines and surgical equipment. Depending on the valve that needs work, a blood vessel in your groin or arm will be prepared. A wire will be placed through your skin to the blood vessel. It will be passed through the blood vessel until it reaches the valve. Progress will be monitored by x-rays. A tube with a balloon tip will be threaded over the wire. A contrast material may be injected through the device. This will help to visualize the area and make sure the device is in the right place. When the balloon is in the valve, it will be inflated and deflated. The inflation may need to be repeated. The device will then be removed from the blood vessel.
You will likely need to lie still and flat on your back for a period of time. A pressure dressing may be placed over the puncture area. It is important to follow the nurses' directions.
Between 30 minutes and two hours
You may feel some minor discomfort when the balloon is inflated. Some people report a flushing sensation if contrast is injected.
Most people are kept overnight for observation. Your doctor may choose to keep you longer if complications arise.
Recovery time is minimal. There will be a bandage over the puncture site. You may be prescribed a blood thinner, like
aspirin. Certain strenuous activities will be limited. Other activities, like exercises and fluid intake, may be encouraged. Your doctor will want to see you several days to weeks later.
Be sure to follow your doctor's
After you leave the hospital, contact your doctor if any of the following occurs:
- Signs of infection, including fever and chills
- Redness, swelling, increasing pain, excessive bleeding, or any discharge from the puncture site
- Pain that you cannot control with the medicines you have been given
- Lightheadedness, fainting, or inability to talk
- Cough, shortness of breath, or chest pain
- An arm or a leg that turns blue or feels cold
- Any other new symptoms
In case of an emergency, call for medical help right away.
