GLOSSARY

This glossary is available to help you understand complicated terms you will see on this website and may hear from your cardiologist, TAVR Specialist, or Heart Valve Team as you learn about severe aortic stenosis, also known as heart valve failure. Be sure to check with your doctor if you have any questions.

A

Aortic Regurgitation

Aortic regurgitation is a form of heart valve disease that occurs when flaps (or leaflets) of the aortic valve do not close properly, which causes blood to leak backwards into the heart.

Aortic Stenosis

This is one of the most common types of heart valve disease. It occurs when there’s a narrowing of the aortic valve due to calcification that prevents normal blood flow out of the heart and makes the heart work harder. Doctors will typically categorize it as mild, moderate, or severe stage which depends on how narrow the valve gets.

Aortic Valve

The aortic valve functions by controlling blood flow from the heart to the aorta (the largest artery that carries oxygen-rich blood to the rest of the body).

Asymptomatic

Showing no symptoms of a heart valve problem yet. Even if you have asymptomatic severe aortic stenosis (heart valve failure), it is still treatable with TAVR by Edwards.

B

Bicuspid Aortic Valve

This is a type of cardiac valve defect. An aortic valve that has only two leaflets (instead of three).

Bioprosthetic Valve

Replacement heart valve made of animal tissue.

E

Echocardiogram (echo)

This diagnostic test uses ultrasound to take pictures of the heart to better assess its function.

Edwards SAPIEN 3 Ultra RESILIA Valve

The latest valve approved in the SAPIEN 3 TAVR family of valves. It is made of cow heart tissue that uses advanced technology to block the buildup of calcium.1

Edwards SAPIEN 3 Valve

An artificial transcatheter heart valve that is made to work like the real aortic valve inside your body, complete with the metal frame, three tissue leaflets, and fabric skirt core to all SAPIEN 3 valves.

H

Heart Failure

When the heart is unable to pump blood to the body’s organs to maintain their function.

Heart Murmur

An abnormal heart sound that may indicate heart valve disease.

Heart Valves

Your heart is a vital organ that depends on its four heart valves (also called cardiac valves). The four valves of the heart help regulate blood flow throughout the body.

Heart Valve Disease (Valvular Heart Disease)

In heart valve disease (valvular heart disease), one or more of the valves of the heart doesn’t properly work. Aortic stenosis is one of the most common types of heart valve disease, affecting over one million people in the US.

Heart Valve Failure

Heart valve failure is another term for severe aortic stenosis. It is a dangerous heart valve problem because the aortic valve has severe buildup of calcium, and has a difficult time opening and closing.

Heart Valve Team

A group of qualified healthcare professionals who work together to determine the best treatment plan for each individual patient.

I

Invasive Procedure

A medical procedure that requires entry into the body, usually by cutting skin and inserting instruments into body.

L

Leaflets

Triangular-shaped flaps of tissue within heart valves that open and close to control blood flow.

P

Progressive Disease

A disease that gets worse over time.

S

SAVR (Surgical Aortic Valve Replacement)

SAVR is the replacement of an aortic valve via open heart surgery. With SAVR, a heart surgeon opens the chest to remove a damaged valve and replaces it with an artificial valve. A heart-lung machine connected to the patient will provide heart and lung functions during the surgery. Most patients stay in the hospital for a week before beginning their long recovery.

T

TAVR (Transcatheter Aortic Valve Replacement)

A minimally invasive procedure that replaces an unhealthy aortic valve with an artificial valve inserted through a catheter. A medical procedure performed with a small incision and specialized equipment.

Tricuspid Aortic Valve

An aortic valve with three leaflets.

U

Ultrasound

A diagnostic test that uses sound waves to look at organs and structures inside the body.
