Balloon valvuloplasty (or valvulotomy) is a procedure in which a tiny
balloon is inserted into the aortic valve and inflated to widen a narrowed
valve (aortic valve stenosis).
During the valvuloplasty procedure, you will be awake, but you will
receive local anesthesia where the catheter is inserted as well as intravenous
(IV) pain medication along with a sedative to help you relax. The procedure
usually is performed on an outpatient basis, so you will be able to go home the
same day. Before leaving, you will have to spend several hours in a recovery
room.
Balloon valvuloplasty is generally an effective treatment for aortic
valve stenosis in teens and young adults but has very limited effectiveness in
older adults. In most older adults, the valve becomes narrowed again
(restenosis) within 6 to 12 months after this procedure.1
Balloon valvuloplasty is more effective in younger people because of
the difference in the causes of aortic valve stenosis in younger and older
people. Young people generally develop the condition because they were born
with a bicuspid valve, which is an aortic valve that has two leaflets instead
of three. Older people, on the other hand, typically develop stenosis over many
years through a gradual hardening and buildup of calcium on their valves, a
process called aortic sclerosis, which is similar to atherosclerosis, the
buildup of hard plaque inside the arteries.
In certain cases, valvuloplasty can also be effective as a "bridge"
to valve replacement for pregnant women or people who have serious medical
conditions that currently make the risk of valve surgery too great.
