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 ...

The aortic valve is made up of three triangular flaps of tissue called cusps that open and close to keep blood flowing in only one direction . Sometimes, the aortic valve opening narrows – a ...

replacement of the diseased cusps have evolved. From our experience with advanced acquired aortic stenosis it is our present opinion that a freely movable valve can be obtained, and that any ...

The aortic valve area can be calculated and measured by planimetry. Detection of sclerodegenerative changes of the aortic cusps in an older asymptomatic individual may be associated with normal ...

It was that final test that found the source of the problem: an extremely rare heart condition called a quadricuspid aortic ...

In addition to the regurgitant jet, echo examination demonstrates structural abnormalities, such as a bicuspid aortic valve or cusp prolapse. Vegetations on the aortic valve, consistent with ...

A late-breaking study presented today at the 2025 Society of Thoracic Surgeons (STS) Annual Meeting reveals that mechanical ...

It's called a bicuspid aortic valve; while a normal heart has three cusps, or leaflets, in the aortic valve, his heart had two. Because the aortic valve controls the flow of blood leaving the ...

There was free aortic regurgitation because of dilatation of the valvular annulus; the cusps themselves were not deformed. The valve was excised and a No. 9 Starr-Edwards valve inserted.

A certain percentage of the energy by the LV is used during opening of the aortic cusps. In healthy individuals with a normal valve, minimal energy is required to open the pliable cusps and hold ...

The aortic valve is particularly important because the aortic valve is the gateway to the rest of the body. So the heart pumps blood through the aortic valve to all the cells in the body.
