Severe Aortic Stenosis & Transcatheter Aortic Valve Replacement (TAVR)

The Transcatheter Aortic Valve Replacement Team

The Transcatheter Aortic Valve Replacement Team at St. Joseph’s Heart Institute has pioneered this innovative new heart valve replacement procedure in Berks County. Known as TAVR (pronounced ‘taver’) this procedure allows specially trained doctors to replace the aortic valve through a minimally invasive procedure similar to catheterization, and is especially useful for cardiac patients who cannot tolerate open heart surgery.

FREQUENTLY ASKED QUESTIONS


What is the aortic valve and aortic stenosis?

When the heart pumps, blood exits the heart and is pumped into a large blood vessel (called the aorta). The aortic valve acts as a one-way gate allowing blood to exit the heart to go into the aorta and then to the rest of the body. Aortic stenosis refers to the narrowing of this valve, restricting the valve’s ability to open and allow normal blood flow. When this valve has narrowed to a certain extent, it is referred to as severe aortic stenosis.

What is severe aortic stenosis?

Severe aortic stenosis is a narrowing of your aortic valve opening that does not allow normal blood flow.

What causes aortic stenosis?

In elderly patients, aortic stenosis is often caused by the build-up of calcium (mineral deposits) on the aortic valve’s leaflets. This build-up of calcium on the leaflets impairs the aortic valve’s ability to fully open and close.

What are the symptoms of aortic stenosis?

When the valve’s leaflets don’t fully open, your heart must work harder to push blood through the narrowed aortic valve to your body. As a result, the narrowed valve allows less oxygen-rich blood to flow from the lungs to the brain and rest of the body which may cause symptoms like severe shortness of breath and extreme fatigue.

How is aortic stenosis diagnosed?

An echocardiogram (ultrasound of the heart) is the primary imaging test used to diagnose severe aortic stenosis.

What is the risk of having severe aortic stenosis?

Eventually, your heart will get weaker, increasing your risk of heart failure. Severe aortic stenosis is a very serious problem. Without aortic valve replacement, 50 percent of patients will not survive more than an average of 2 years after they start having symptoms.

What is the treatment for severe aortic stenosis?

Currently, there is no medicine to treat aortic stenosis. Aortic valve replacement is the treatment for severe symptomatic aortic stenosis. This is usually done through open-heart surgery.

What if I’m not a candidate for open heart surgery?

If you have factors such as age, history of heart disease, frailty or other health issues, you may not be a candidate for open-heart surgery. However, a new therapy called Transcatheter Aortic Valve Replacement (TAVR) may be an option.

What is TAVR?

TAVR is a procedure that allows Heart Teams to replace a diseased aortic heart valve without open-heart surgery. This procedure enables the placement of a balloon-expandable heart valve into the body with a tube-based delivery system (catheter), which allows the valve to be inserted through a small cut in the thigh into an artery.

How can I find out if I’m eligible for TAVR?

If a cardiac surgeon determines you are too sick for open heart surgery and if medicine is not helping you feel better, TAVR might be an alternative. A Heart Team will conduct a comprehensive evaluation to determine whether this procedure is an appropriate therapeutic option. In certain cases, TAVR may not be an option because of co-existing medical conditions or disease processes that would prevent you from experiencing the expected treatment benefit or because the risks outweigh the benefits. For those who are candidates for TAVR, this therapy may provide relief from the often debilitating symptoms associated with severe symptomatic native aortic valve stenosis.

What are the risks of TAVR?

TAVR is a significant procedure involving general anesthesia, and placement of the valve is associated with specific contraindications as well as serious adverse effects, including risks of death, stroke, damage to the artery used for insertion of the valve, major bleeding, and other life-threatening and serious events. In addition, the longevity of this valve has not yet been determined since this is a new procecure.

How long will I be in the hospital with TAVR?

The surgery is performed under general anesthesia and the procedure usually takes 3 to 4 hours. The average hospital stay is 4 to 7 days.

What happens after TAVR?

While in the hospital after TAVR, the following examinations will be completed:

Physical exam
Chest X-ray
Blood tests
Telemetry (monitoring of the heart’s rhythm)

You will remain in ICU until your doctor feels you can be transferred to a regular hospital room, where you will continue to be monitored. A physical therapist will evaluate you and help you start moving as soon as possible. The average ICU time is 1 day and the average entire hospital stay for the procedure is 4 to 7 days.

You may be given blood-thinning medicine for 6 months and aspirin for the rest of your life, unless otherwise specified by your doctor. Regular check-ups by your doctor are very important.
