Anesthesia

Temporary loss of feeling or awareness induced by a medical professional during a surgical procedure.

Angina

Chest pain caused by poor blood supply to the heart.

Angiogram

A medical imaging test that uses x-rays and dyes to see how blood flows through an artery or a vein.

Angioplasty

A procedure that uses an inflatable balloon on a thin tube to internally widen a narrowed blood vessel.

Aortic Stenosis

Narrowing of the aortic valve that prevents normal blood flow and makes the heart work harder.

Aortic Valve

The valve that controls blood flow from the heart to the aorta (largest artery that carries blood to the rest of the body).

Artery

Blood vessel that carries oxygen-rich blood to the body.

Atrial Fibrillation (AFib)

Irregular heart rhythm caused by abnormal electrical signals throughout the upper chambers of the heart.

Auscultation

Listening to the sounds of your heart using a stethoscope.

B

Balloon Valvuloplasty (BAV)

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

Bioprosthetic Valve

Replacement heart valve made of animal tissue (cow or pig).

C

Calcification

A build-up of calcium on tissue. In the aortic valve, it can reduce the ability for leaflets to open and close properly.

Cardiothoracic Surgeon

Surgeon who performs heart surgery.

Catheter

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.

Catheterization

A procedure in which a slender tube is inserted into a body passage, vessel or cavity.

Chest x-ray

A type of imaging that displays images of the organs and structures inside your chest, such as your heart, lungs, and large blood vessels.

Chronic Obstructive Pulmonary Disease (COPD)

A chronic condition in which there is a slow, progressive block of airflow into or out of the lungs.

Coronary Artery Disease

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.

D

Delivery System

A medical tool used to guide the transcatheter valve.

Diabetes

A condition in which your blood glucose, or blood sugar, is too high.

Diagnostic Tests

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).

Download

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.

Dyspnea

Shortness of breath.

E
Back to Top
Echocardiogram (echo)

This diagnostic test uses sound wave technology, or ultrasound, to show three-dimensional images of the heart to better assess its function.

Electrocardiogram (EKG)

A diagnostic test that records electrical activity in the heart, such as heart rate and rhythm.

F
Back to Top
Fatigue

A feeling of being extremely tired or having low energy.

Femoral Artery

The largest blood vessel in the leg that supplies blood to the lower part of the body.

Fluoroscopy

An x-ray procedure that makes it possible to see internal organs in motion.

Frailty

Increased physical and mental weakness that is often associated with older age.

H

Heart and Lung Blood Machine

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.

Heart Failure

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

Heart Murmur

An abnormal heart sound that may indicate heart valve disease.

Heart Team

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

I

Intermediate or greater risk

Risk is assessed by evaluating a patient’s current health and likelihood of experiencing major complications as a result of undergoing open heart surgery.

Interventional Cardiologist

Doctor who specializes in catheter-based treatments for the heart or coronary artery diseases (in most cases this is the doctor who performs TAVR).

Invasive Procedure

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

L
Back to Top
Leaflets

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

Less Invasive Procedure

A medical procedure performed with a small incision and specialized equipment.

M
Back to Top
Magnetic Resonance Imaging (MRI)

A diagnostic test that uses magnetic and radio waves to take detailed pictures of the heart and other organs.

Mechanical Heart Valve

Replacement heart valve made of artificial materials. Once inserted in the body, lifelong blood thinning medication is required.

Metastasize

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.

Minimal Incision Valve Surgery

A surgical technique for replacing a diseased valve that does not require a large incision or cutting through the entire breastbone.

Minimally-Invasive Procedure

A procedure that can be performed through a small incision, which typically leads to a faster recovery.

Mitral Valve

The valve that controls blood flow from the heart’s left upper chamber to the left lower chamber.

P
Back to Top
Peripheral Vascular Disease (PVD)

A disease of the blood vessels resulting in a decrease in circulation to the legs, arms, stomach or kidneys.

Progressive

Relating to disease, a condition that will continue to get worse.

Pulmonary Valve

The valve that controls blood flow from the heart into the lungs.

R
Back to Top
Rheumatic Fever

Inflammation that occurs throughout the body, especially in the heart, if strep throat goes untreated.

S
Back to Top
Sheath

A tube placed in an artery or vein during a procedure to help a doctor with insertion of catheter.

Stroke

The sudden death of brain cells due to lack of oxygen, caused by blockage of blood flow to the brain.

Subclavian Approach

A way to replace your aortic valve through a small incision near the shoulder.

Syncope

Temporary loss of consciousness or fainting.

T

TAVR Doctor

A doctor at a TAVR Hospital who can evaluate you for all of your treatment options and perform your TAVR procedure.

Transaortic Approach

A way to replace your aortic valve through a small incision in the upper chest.

Transapical Approach

A way to replace your aortic valve through a small incision in the chest between the ribs.

Transcatheter Aortic Valve Replacement

A less invasive procedure that replaces an unhealthy aortic valve.

Transfemoral Approach

A way to replace your aortic valve through a small incision in the leg.

Tricuspid Valve

The valve that controls blood flow from heart’s upper right chamber to lower right chamber.

U

Ultrasound

A diagnostic test that uses sound waves to obtain images of blood flow and your body’s internal structure.

V
