This glossary is available to help you understand complicated terms you will see on this website and may hear from your cardiologist, TAVR Doctor, or Heart Team as you learn about aortic stenosis. Be sure to check with your doctor if you have any questions.
ABACK TO TOP
Temporary loss of feeling or awareness induced by a medical professional during a surgical procedure.
Chest pain caused by poor blood supply to the heart.
A medical imaging test that uses x-rays and dyes to see how blood flows through an artery or a vein.
A procedure that uses an inflatable balloon on a thin tube to internally widen a narrowed blood vessel.
Narrowing of the aortic valve that prevents normal blood flow and makes the heart work harder. Doctors will typically measure it as mild, moderate, or severe aortic stenosis. The stage of aortic stenosis depends on how damaged your aortic valve is.
The valve that controls blood flow from the heart to the aorta (largest artery that carries blood to the rest of the body).
Blood vessel that carries oxygen-rich blood to the body.
Irregular heart rhythm caused by abnormal electrical signals throughout the upper chambers of the heart.
Listening to the sounds of your heart using a stethoscope.
BBACK TO TOP
A procedure in which a balloon catheter is inserted through an artery into the heart. The balloon is then inflated to open the narrowed valve.
An aortic valve that has only two leaflets (instead of three).
Replacement heart valve made of animal tissue (cow or pig).
CBACK TO TOP
A buildup of calcium on tissue. In the aortic valve, it can reduce the ability for leaflets to open and close properly.
Surgeon who performs heart surgery.
A thin, hollow tube, either flexible or non-flexible, that is used to add, remove or transfer fluids or instruments used in minimally-invasive procedures.
A procedure in which a slender tube is inserted into a body passage, vessel or cavity.
A type of imaging that displays images of the organs and structures inside your chest, such as your heart, lungs, and large blood vessels.
A chronic condition in which there is a slow, progressive block of airflow into or out of the lungs.
A type of heart disease which happens when the arteries that supply blood to the heart muscle become hardened and narrowed due to build-up of plaque on the artery walls.
An infectious disease caused by a type of virus called a coronavirus. Effects from COVID-19 infection can range from no symptoms to severe illness and death.
DBACK TO TOP
A medical tool used to guide the transcatheter valve.
A condition in which your blood glucose, or blood sugar, is too high.
Tests that help your doctor confirm if you have aortic stenosis. Some of these tests include echocardiogram (also called echo), cardiac catheterization, chest x-ray, and electrocardiogram (also called EKG).
To receive a copy of a file, program or document that can be saved and viewed from your computer. The downloaded file may open in a separate window, may be minimized at the bottom of the web browser, or may be located within your computer’s downloads folder.
Shortness of breath.
EBACK TO TOP
This diagnostic test uses sound wave technology, or ultrasound, to show three-dimensional images of the heart to better assess its function.
A diagnostic test that records electrical activity in the heart, such as heart rate and rhythm.
FBACK TO TOP
A feeling of being extremely tired or having low energy.
The largest blood vessel in the leg that supplies blood to the lower part of the body.
An x-ray procedure that makes it possible to see internal organs in motion.
Increased physical and mental weakness that is often associated with older age.
HBACK TO TOP
A device used during open heart procedures to remove blood from the body. The blood is enriched with oxygen and then returned to the body.
When the heart is unable to pump blood to the body’s organs and maintain their function.
An abnormal heart sound that may indicate heart valve disease.
A group of qualified healthcare professionals who work together to determine the best treatment plan for each individual patient.
IBACK TO TOP
A doctor who specializes in catheter-based treatments for the heart or coronary artery diseases (in most cases this is the doctor who performs TAVR).
A medical procedure that requires entry into the body, usually by cutting skin and inserting instruments into body.
LBACK TO TOP
Triangular-shaped flaps of tissue within heart valves that open and close to control blood flow.
A medical procedure performed with a small incision and specialized equipment.
MBACK TO TOP
A diagnostic test that uses magnetic and radio waves to take detailed pictures of the heart and other organs.
Replacement heart valve made of artificial materials. Once inserted in the body, lifelong blood thinning medication is required.
The spread of cancer cells from the place where they first formed to another part of the body. In metastasis, cancer cells break away from the original tumor, travel through the blood or lymph system, and form a new tumor in other organs or tissues of the body.
A surgical technique for replacing a diseased valve that does not require a large incision or cutting through the entire breastbone.
A procedure that can be performed through a small incision, which typically leads to a faster recovery.
The valve that controls blood flow from the heart’s left upper chamber to the left lower chamber.
PBACK TO TOP
A disease of the blood vessels resulting in a decrease in circulation to the legs, arms, stomach or kidneys.
Relating to disease, a condition that will continue to get worse.
The valve that controls blood flow from the heart into the lungs.
RBACK TO TOP
Inflammation that occurs throughout the body, especially in the heart, if strep throat goes untreated.
SBACK TO TOP
A tube placed in an artery or vein during a procedure to help a doctor with insertion of catheter.
The sudden death of brain cells due to lack of oxygen, caused by blockage of blood flow to the brain.
A way to replace your aortic valve through a small incision near the shoulder.
Temporary loss of consciousness or fainting.
TBACK TO TOP
A less invasive procedure that replaces an unhealthy aortic valve.
A doctor at a TAVR Hospital who can evaluate you for all of your treatment options together with a Heart Team and who performs your TAVR procedure.
A way to replace your aortic valve through a small incision in the upper chest.
A way to replace your aortic valve through a small incision in the chest between the ribs.
A way to replace your aortic valve through a small incision in the leg.
The valve that controls blood flow from heart’s upper right chamber to lower right chamber.
UBACK TO TOP
A diagnostic test that uses sound waves to obtain images of blood flow and your body’s internal structure.
VBACK TO TOP
Blood vessels that return blood to the heart.
