Valvuloplasty may be done to open a stiff (stenotic) heart valve. In valvuloplasty, your doctor inserts a very small, narrow, hollow tube (catheter) into a blood vessel in the groin and advances it through the aorta into the heart. Once the catheter reaches the stiff valve, your doctor inflates a large balloon at the tip of the catheter until the flaps (leaflets) of the valve are pushed opened. Once the valve has been opened, the doctor deflates the balloon and removes the catheter.
To keep the blood flowing forward during its journey through the heart, there are valves between each of the heart's pumping chambers:
Valvuloplasty may be done to open a heart valve that has become stiff. But, not all conditions in which a heart valve becomes stiff are treatable with valvuloplasty.
If the heart valves become damaged or diseased, they may not work properly. Conditions that may cause problems with the heart valves are valvular stenosis (stiffened valve) and valvular regurgitation (leaky valve). When one (or more) valve(s) becomes stiff, the heart muscle must work harder to pump the blood through the valve. Stiff valves may be caused by infection (such as rheumatic fever or staphylococcus infections), birth defects, and aging. If one or more valves become leaky, blood leaks backwards and less blood is pumped in the proper direction.
Heart valve disease may cause the following symptoms:
There may be other reasons for your doctor to recommend a valvuloplasty.
Possible risks of valvuloplasty include:
If you are pregnant or think you could be, tell your healthcare provider due to risk of injury to the fetus from a valvuloplasty. Radiation exposure during pregnancy may lead to birth defects. Also tell your provider if you are lactating, or breastfeeding.
There is a risk of allergic reaction to the dye. If you are allergic or sensitive to medicines, contrast dyes, iodine, or latex should, tell your doctor. If you have kidney failure or other kidney problems, tell your doctor.
Some people may find lying still on the procedure table for the length of the procedure may cause some discomfort or pain.
There may be other risks depending on your specific medical condition. Be sure to discuss any concerns with your doctor before the procedure.
A valvuloplasty may be done as part of your stay in a hospital. Procedures may vary depending on your condition and your doctor’s practices.
Generally, a valvuloplasty follows this process:
After the procedure, you may be taken to the recovery room for observation or returned to your hospital room. You will remain flat in bed for several hours after the procedure. A nurse will monitor your vital signs, the insertion site, and circulation and sensation in the affected leg or arm.
Tell your nurse right away if you feel any chest pain or tightness, or any other pain, as well as any feelings of warmth, bleeding, or pain at the insertion site in your leg or arm.
Bed rest may vary from 2 to 6 hours depending on your specific condition. If your doctor placed a closure device, your bed rest may be of shorter duration.
In some cases, the sheath or introducer may be left in the insertion site. If so, your period of bed rest will be longer. After the sheath is removed, you may be given a light meal.
You may be given medicine for pain or discomfort related to the insertion site or having to lie flat and still for a prolonged period.
You will be encouraged to drink water and other fluids to help flush the contrast dye from your body.
You may feel the urge to urinate often because of the effects of the contrast dye and increased fluids. You will need to use a bedpan or urinal while on bed rest so that you don't bend your affected leg or arm.
You may resume your usual diet after the procedure, unless your doctor decides otherwise.
After the specified period of bed rest, you may get out of bed. The nurse will help you the first time you get up, and may check your blood pressure while you are lying in bed, sitting, and standing. Move slowly when getting up from the bed to avoid any dizziness from the long period of bed rest.
You will most likely spend the night in the hospital after your procedure. Depending on your condition and the results of your procedure, your stay may be longer. You will receive detailed instructions for your discharge and recovery period.
Once at home, watch the insertion site for bleeding, unusual pain, swelling, and discoloration or temperature change at or near the injection site. A small bruise is normal. If you notice a constant or large amount of blood at the site that cannot be contained with a small dressing, call your doctor.
If your doctor used a closure device for your insertion site, you will be given specific information about how to take care of the insertion site. There will be a small knot, or lump, under the skin at the injection site. This is normal. The knot should gradually disappear over a few weeks.
It will be important to keep the insertion site clean and dry. Your doctor will give you specific bathing instructions.
Your doctor may advise you not to participate in any strenuous activities. Your doctor will tell you when you can return to work and resume normal activities.
Tell your doctor to report any of the following:
Your doctor may give you other instructions after the procedure, depending on your particular situation.
