Transcatheter Aortic Valve Replacement (TAVR) – Holston Valley
Minimally invasive TAVR procedure in Kingsport, Tennessee
What is TAVR?
TAVR is a less invasive procedure for treating severe symptomatic aortic stenosis that does not require open heart surgery.
During the TAVR procedure, a prosthetic (artificial) valve is inserted within the native, diseased aortic valve.
The TAVR procedure can be performed through multiple approaches:
- Transfemoral – done through the femoral artery, which involves an incision in the groin area
- Transaortic – done through the aorta or aortic valve of the heart
- Transapical – requires the breastbone be opened
Benefits of TAVR
- Relief of symptoms, in some cases immediately
- Reduction of pain and anxiety
- Improved heart function
- Potentially shorter recovery time (when compared to traditional open-heart surgery)
Quality of life improvement
TAVR has shown improvement in patients’ health as early as 30 days after the procedure.
Patients reported improvement in quality of life, including:
- Ability to take care of themselves
- Ability to participate in everyday activities

What is severe aortic stenosis?
Severe aortic stenosis causes a narrowing or obstruction of the heart’s aortic valve. It is usually caused by calcium deposits that accumulate over time on the valve’s leaflets, the flaps of tissue that open and close to regulate the flow of blood in one direction through the valve.
This condition affects the valve’s ability to open and close properly, causing the heart to work harder and increasing the risk of heart failure.
Aortic stenosis is typically a disease of older patients, as calcium gradually builds up gradually over the years.
Aortic stenosis facts
It’s estimated that about 12.4% of people in the U.S. over age 75 – about 2.5 million people – suffer from aortic stenosis.1,2
Between now and the year 2050, the senior population will more than double to 80 million,3 so the population at risk for aortic stenosis will continue growing.
Aortic stenosis is also more likely to affect men than women. 80% of adults with symptomatic aortic stenosis are male.5
What are the symptoms of aortic stenosis?
The symptoms of aortic disease are often misunderstood to be “normal” signs of aging.
Many patients don’t appear to have symptoms initially, but when examined more closely, up to 32% show symptoms.2
These symptoms include:
- Shortness of breath
- Syncope or presyncope
- Difficulty when exercising
- Swollen ankles and feet
- Rapid or irregular heartbeat
- Palpitations (an uncomfortable awareness of heart beating rapidly or irregularly)
However, it’s important to realize severe aortic stenosis may occur with no outward symptoms.
Why treatment is critical
It is possible to live with aortic stenosis without symptoms for many years.
However, once symptoms being, even normal day-to-day activities such as walking short distances or climbing stairs can become very challenging.
And without treatment, symptomatic aortic stenosis will eventually lead to death.
After symptoms start, patients with severe aortic stenosis have a survival rate as low as 50% after 2 years and 20% at 5 years without aortic valve replacement.5
If you are experiencing symptoms, it’s urgent that you see your doctor for treatment.6
How is aortic stenosis diagnosed?
There are multiple tools your doctor can use to determine if you have severe aortic stenosis.
Of those tools, echocardiograms are one of the best ways to diagnose the disease.1
How do I get started?
If you think you might have aortic stenosis or might be a candidate for TAVR, please contact the structural heart coordinator at (423) 230-6916.
Or speak to your primary care provider.
