If you decide on surgery to repair your
mitral valve stenosis, you and your doctor will need
to select either a balloon valvotomy or a mitral commissurotomy. In spite of
similar success rates, a balloon valvotomy is generally preferred to mitral
commissurotomy as long as the doctor is experienced with the procedure.
Balloon valvotomy is catheter-based, not surgical, and has a lower risk
of complications and death than mitral commissurotomy. But a balloon valvotomy
done by an inexperienced cardiologist has approximately the same
percentage of negative outcomes as that seen with a commissurotomy. So
it is important that you have your balloon valvotomy done at a medical
center that routinely does a large number of these procedures.
Angina -- Discomfort, pain, or pressure in the chest caused by an inadequate blood supply to the heart. Pain may also be felt in the neck, jaw, or arms.
Angiogram (cardiac catheterization) -- A test used to diagnose heart disease. During the procedure a catheter is inserted into an artery, usually in the leg, and contrast dye is injected into the arteries and heart. X-rays of the arteries and heart are taken.
Anticoagulant -- A medication that prevents blood from clotting; used for...
Both procedures have risks, but the risks are rare. Most commonly,
"cracking open" valve leaflets will cause the valve to begin to leak, causing
mitral regurgitation. There is also a slight chance
that a blood clot will develop in your heart and cause a
stroke. But the most common problem with both
procedures is that they typically need to be repeated after 10 or 20 years
because the valve becomes narrowed again. At this point, you may need a valve
replacement due to damage done to the leaflets during the earlier
