Aortic Stenosis is a common heart valve problem affecting millions of people
in the United states. It is estimated that up to 12.4% of people over
age 75 have aortic stenosis and it is most common in men.
Over time, the aortic valve becomes stiff, reducing the ability to fully
open and close. This results in the heart working harder to push blood
through the aortic valve to the body. Eventually, this weakens the heart
and increases the risk of heart failure because the heart cannot supply
enough blood to the body.
Aortic stenosis can be caused by age, calcium build-up, radiation therapy,
infection of the heart, birth defects, and rheumatic fever.
As the heart works harder and less oxygen-rich blood flows through the
body, symptoms may result. Symptoms can include, chest pain, rapid/fluttering
heartbeat, trouble breathing or feeling short of breath, feeling dizzy
or light-headed, fainting, difficulty walking short distances, swollen
ankles or feet, not doing activities you used to enjoy, difficulty sleeping
or the need to sleep sitting up. Because these symptoms are common to
other health problems, it’s important to discuss them with your doctor.
How is Aortic Stenosis Treated With a Transcatheter Heart Valve Replacement (TAVR)?
For decades, the previous standard of care has been open-heart surgery
for aortic valve replacement. TAVR offers an alternative method for many
patients. During this minimally invasive approach, the valve is typically
implanted through the femoral artery, although other access points may
be used. TAVR can be an effective option to improve the quality of life
in patients who otherwise have limited choices for the repair of their
aortic valve.
Without aortic valve replacement, severe aortic stenosis is a life-threatening
disease and carries a poor short-term prognosis, with a survival rate
as low as 50% within two years of symptom development.
Prior to treatment, patients are evaluated within Excela’s Structural
Heart Program by a multidisciplinary team that includes cardiothoracic
surgeons, interventional cardiologists, cardiovascular imagers, cardiac
anesthesiologists and nurse navigators. The team reviews cardiac imaging,
coronary angiography and CT scans along with clinical history to make
the best clinical decision for each patient.
A TAVR typically takes less than an hour to complete, and patients can
expect to spend less time in the hospital after TAVR compared to traditional
surgical valve replacement.
