What is a normal aortic valve gradient?

A normal aortic valve area is greater than or equal to 2.0 cm2. Mild aortic stenosis: Valve area is between 1.5-2.0 cm2 with a pressure gradient of less than 25 mmHg. Moderate aortic stenosis: Valve area is 1.0-1.5 cm2 with a gradient of 25-40 mmHg.

Keeping this in consideration, what is the definition of pressure gradient?

In atmospheric science (meteorology, climatology and related fields), the pressure gradient (typically of air, more generally of any fluid) is a physical quantity that describes in which direction and at what rate the pressure increases the most rapidly around a particular location.

What is pore pressure gradient?

Pore pressure gradient is a dimensional petrophysical term used by drilling engineers and mud engineers during the design of drilling programs for drilling (constructing) oil and gas wells into the earth.

What is normal mitral valve area?

The normal area of the mitral valve orifice is about 4 to 6 cm2. In normal cardiac physiology, the mitral valve opens during left ventricular diastole, to allow blood to flow from the left atrium to the left ventricle. Eventually, the left ventricle requires the atrial kick to fill with blood.
