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 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 ...

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 ...

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 ... has a rough correlation with severity, although cusp separation by M-mode echocardiography of 12 mm or greater suggests absence of critical stenosis.
