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.

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.
- Biological valve
Replacement heart valve made of animal tissue (cow or pig).
A build-up of calcium on tissue. In the aortic valve, it can reduce the ability for leaflets to open and close properly.
- Cardiac care rehabilitation
A medically supervised care program designed to improve the health of people who have had heart problems or recent heart surgery.
- Cardiothoracic surgeon
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.
- 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.
- Congenital defect
A problem with the structure of the heart that is present at birth.
- Conscious sedation
A type of sedation that relaxes you and blocks pain while awake.
- 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.
- Delivery system
A medical tool used to guide the transcatheter valve.
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 catheterisation, chest X-ray, and electrocardiogram (also called EKG).

Shortness of breath.
- 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.
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.
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.
- 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 attack
A medical emergency that occurs when blood flow is blocked to the heart, leading to death or damage to the heart.
- 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.
- Heart valve disease
A common condition in which the heart valves do not work the way they should.
- Intensive care unit (ICU)
A hospital unit that provides constant care to patients.
- 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 specialises in catheter-based treatments for the heart or coronary artery diseases (in most cases this is the doctor who performs TAVI).
- Invasive procedure
A medical procedure that requires entry into the body (usually by cutting skin and inserting instruments into body) and involves a longer recovery period.
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 specialised equipment.
- Life-threatening bleeding event
Dangerous blood loss due to blood vessel injury.
- Local anaesthesia
A drug that temporarily numbs a small area of the skin.
- 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.
- 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.
- Open heart surgery
A surgical procedure where the chest is cut open to repair damage to the heart.
- Peripheral vascular disease (PVD)
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.
- Pulmonary valve
The valve that controls blood flow from the heart into the lungs.
- Rheumatic fever
Inflammation that occurs throughout the body, especially in the heart, if strep throat goes untreated.
A tube placed in an artery or vein during a procedure to help a doctor with insertion of catheter.
An instrument used by a medical professional to listen to low-volume sounds in the body such as a heartbeat.
The sudden death of brain cells due to lack of oxygen, caused by blockage of blood flow to the brain.
Temporary loss of consciousness or fainting.

- Vascular complication
Blood vessel injury or internal bleeding.
Blood vessel that returns blood to the heart.
