Glossary
Abdomen: The part of the body that lies between the chest and waist.
Aorta: The major blood vessel leaving the left ventricle. The vessel passes blood to arteries throughout your body.
Apex: Blunt rounded end of the heart, directed downward, forward, and to the left.
Artery: Blood vessels that carry blood away from the heart to the various parts of the body.
Atrium: An upper chamber of the heart. Right atrium receives unoxygenated blood from the body. Left atrium receives oxygenated blood from the lungs.
Cardiac Cycle: One total heartbeat, one complete contraction and relaxation of the heart.
Cardiovascular: Pertaining to the heart and blood vessels
Centrifugal Pump Technology: As blood is drawn into the pump, a paddlewheel like component (impeller) forces the blood toward the outside walls and expels it through an opening.
Congestive Heart Failure: A condition in which the heart has difficulty pumping enough blood. Symptoms can include weakness, shortness of breath and swelling of the legs.
Dilated: To become wider, larger; expand.
Dyspnea: Difficult or labored breathing.
Impeller: A propulsion device that draws liquid in and forces it through an opening.
Left Atrium: Receives oxygen-rich blood from the lungs and passes it to the left ventricle.
Left Ventricle: Receives blood from the left atrium and pumps it through the aorta to circulate throughout the body.
Left Ventricular Assist System: A class of medical devices that helps the left side of the heart pump oxygen-rich blood through the body. Also called a Left Ventricular Assist Device.
LVAD: Acronym for Left Ventricular Assist Device. Same as Left Ventricular Assist System (LVAS).
LVAS: Acronym for Left Ventricular Assist System. A device designed to help the left side of the heart to pump blood to the body.
Magnetic Levitation: Through electromagnetics and position sensors, the impeller is suspended within the blood chamber.
Mechanical Circulatory Support (MCS): A type of treatment used for end-stage heart failure patients. As the population continues to age and heart failure rates continue to grow, MCS is becoming a more frequent alternative for patients.
Occlusion: Venous or arterial occlusion is a state of being closed or shut
Percutaneous: Passed through the skin
Pulmonary Artery: Receives blood from the right ventricle and carries it to the lungs to be “refueled” with oxygen.
Right Atrium: Receives oxygen-poor blood from the body and passes it to the right ventricle.
Right Ventricle: Receives blood from the right atrium and pumps it through the pulmonary artery to the lungs to pick up oxygen.
Thromboembolism: Occurs when a blood clot forms and then breaks off and travels to another part of the body via the bloodstream.
