Middle-aged adults who need an aortic valve replacement fare better with mechanical devices than with the valves made from animal tissues that they currently most often receive, U.S. researchers ...

THE human aortic valve consists of three cusps made of relatively inelastic, muscle-free material about 0.15 mm thick. It opens and shuts about once a second, and withstands a pressure difference ...

At baseline, the mechanical valve group tended to be younger (55.7 vs 65.2) and had less aortic stenois (82.4% vs 89.5%), but ...

As your heart beats, it pumps blood from the left ventricle through the aortic valve and into the aorta, your body’s largest artery. The aortic valve is made up of three triangular flaps of ...

Description Aortic stenosis occurs when the aortic valve, which separates the main pumping chamber of the heart from the circulation, becomes narrowed. This may reduce the flow of blood out of the ...

The researchers reviewed data on nearly 110,000 patients who underwent surgical replacement of aortic valves between the ages of 40 and 79. They found that in those aged 60 or younger, mechanical ...

According to one large series, if aortic valve replacement is not performed ... O2 demand = wall stress X HR. Using the above equation, we can understand the pathologic process that develops ...

Aortic regurgitation occurs when blood flows retrograde (backwards) across the aortic valve from the aorta into the left ventricle during diastole. This abnormal backflow of blood leads to patholo ...
