Your aortic valve is part of your heart, a strong muscle that pumps blood through your body. The aortic valve controls the blood flowing out from the heart. It opens every time your heart contracts, or squeezes. This allows blood to flow out into the aorta. Then the aortic valve shuts ...
valvular aortic stenosis (AS)echocardiographic screeningunicommissural typeA valve that is located between and controls the flow of blood from the left ventricle of the heart and the aorta.Blackwell PublishingHandbook of Echo-Doppler Interpretation, Second Editiondoi:10.1002/9780470988435.ch7...
The aortic valve controls blood flow from the heart's main pumping chamber into the body's largest arterial trunk. Stenosis (narrowing) at the valve reduces the outward flow of oxygenated blood and leads to congestive heart failure as the organ stretches to accommodate a greater-than-...
The aortic valve controls blood flow from the heart into the aorta, the main artery that feeds blood to most of the body. When the valve doesn't work correctly, patients may need a replacement to preserve function of the heart muscle and prevent issues such as heart failure or sudden cardi...
Porting valve - This valve opens and closes to let the hydraulic fluid flow from one side of the artificial heart to the other. When the fluid moves to the right, blood gets pumped to the lungs through an artificial ventricle. When the fluid moves to the left, blood gets pumped to the...
A dissecting aneurysm, also called aortic dissection (AD), is caused by rupture of the aorta, which flows from the inner hole to the middle layer, causing the wall to be disformed and the blood flow to extend along the longitudinal axis.7Clinical classification of AD and AA are mainly for...
Purpose: To investigate age-related changes in peak systolic aortic 3D velocity and wall shear stress (WSS) in healthy controls and to investigate the importance of age-matching for 3D mapping of abnormal aortic hemodynamics in bicuspid aortic valve disease (BAV). Materials and methods: 4D flow ...
(redirected from Bicuspid aortic valve)Also found in: Dictionary, Thesaurus, Medical, Acronyms, Wikipedia. valve valve, device for controlling the flow of fluids (liquids and gases). Valves vary in construction and size depending upon their function. Some are classified according to their method ...
Blood flow from the proximal to distal aorta through the Gott shunt is variable and governed by the proximal aortic pressure, diameter and length of the shunt, and distal aortic pressure. Monitoring the distal aortic pressure through a femoral arterial catheter can be used to assess distal aortic...
Microbial isolates were cultured from blood and from excised valves. Fig. 1 Study flow chart Full size image Most of the included patients were treated with AVR (98.8%), while the remainder were treated with aortic valve repair. Coronary artery bypass grafting (CABG) was concurrently performed ...
