Aortic Valve definition: The valve between the left ventricle and the ascending aorta which prevents backflow into the left ventricle.
aortic valve definition: valve between the left ventricle and the ascending aorta which prevents backflow into the left ventricle.
Aortic valve definition: Cardiac valve which has as its parts the anterior, right posterior and left posterior cusps, attached to the fibrous ring of aortic valve.
Aortic Valve definition: A valve that is located between and controls the flow of blood from the left ventricle of the heart and the aorta.
Heart Valve Prosthesis definition: A device that substitutes for a heart valve. It may be composed of biological material (BIOPROSTHESIS) and/or synthetic material.
prosthetic heart valve definition: device that substitutes for a heart valve; may be composed of biological material and/or synthetic material.
Prostheses, Cardiac Valve definition: Prostheses designed to replace natural heart valves. These prostheses may consist of biological or artificial valves. Bioprosthetic valves consist of either processed cardiac valves from human cadavers (i.e., allografts) or animals (i.e., xenografts) or valves manufactured from tissue (e.g., pericardium, dura mater) taken from the same sources. Artificial valves are typically made of metals and plastics or silicone rubber. Cardiac valve prostheses are available in appropriate sizes and configurations to replace any of the cardiac valves, namely the mitral, tricuspid, aortic, and pulmonary valves. These prostheses are indicated for patients in whom extensive valvular damage resulting from acquired or congenital diseases precludes repair.
VALVE, PROSTHESIS definition: An external limb prosthetic component is a device intended for medical purposes that, when put together with other appropriate components, constitutes a total prosthesis. Examples of external limb prosthetic components include the following: Ankle, foot, hip, knee, and socket components; mechanical or powered hand, hook, wrist unit, elbow joint, and shoulder joint components; and cable and prosthesis suction valves.
Heart Valves definition: Flaps of tissue that prevent regurgitation of BLOOD from the HEART VENTRICLES to the HEART ATRIA or from the PULMONARY ARTERIES or AORTA to the ventricles.
heart valve definition: flaps of tissue that prevent regurgitation of blood from the heart ventricles to the heart atria or from the pulmonary arteries or aorta to the ventricles.
