Aortic stenosis is a narrow place in the
aortic valve or around the valve. In normal
blood flow, the blood leaves the left
ventricle and passes through the aortic valve
out to the rest of the body. The narrower the
opening in the valve, the harder it is for the
left ventricle to pump the blood. The
narrow place can be in the valve itself or in
the muscles just below the valve. The left
ventricle can become enlarged or thickened.
There may be some fatigue and problems
with exercise. Infants may have problems
eating. Often a murmur is heard on exam.
Infants with severe aortic stenosis may need
medical treatment right away. Individuals
with mild narrowing will be watched by the
cardiology team. Some people may need
treatment with medicines. The
echocardiogram (heart ultrasound) will
check the amount of narrowing and the size
of the left ventricle.
Aortic stenosis that is determined to need
treatment may be treated in the cardiac
catheterization lab. The doctor will pass a
balloon thru the valve. The balloon is
inflated to open up the narrow place. Then,
the balloon is removed.
Surgery may be needed to repair the narrow
place. There are four types of repair. The
cardiologist and surgeon will help you
decide which method is best.
▪ Valvotomy – The aortic valve is
rebuilt to allow blood to pass through
more easily. If the narrow place is
caused by tissue or muscles
underneath the valve, these may be
removed as well.
▪ Ross procedure – The aortic valve
is replaced with the person’s own
pulmonary valve. A pulmonary
valve or tube is then placed where
the pulmonary valve had been.
▪ Subaortic stenosis membrane
resection – The membrane causing
the narrow place is removed. This
allows the blood to pass freely out of
the left ventricle.
▪ Valve replacement – The aortic
valve is replaced with either a
mechanical valve or a valve from a
human or animal donor.
