What is the normal aortic valve opening size?

The normal size of the aortic valve area (AVA) at maximum opening of the valve is 3 to 4 cm2 [2]. When the AVA decreases below 1 cm2, AS is considered to be severe [3].

What is the size of the aortic valve?

Specific to size, a normal aortic valve area is >2 centimeters squared (cm2).

What is the average diameter of aortic valve?

For adult women, the mean aortic valve diameter was 21.0 +/- 1.8 mm (n = 1156) and the mean pulmonary valve diameter was 23.9 +/- 2.2 mm (n = 1408). The mean indexed aortic valve area was 2.02 +/- 0.52 cm(2)/m(2) and the pulmonary valve area 2.65 +/- 0.52 cm(2)/m(2).

What is critical aortic valve area?

“Critical aortic stenosis” occurs when the valve area is < 0.7 cm2, at which point the transvalvular gradient will be 50 mm Hg at rest (ie with a normal cardiac output) – at 0.7 cm2/50 mm Hg, patients cannot appreciably increase their cardiac output.

What is the size of an aortic valve replacement?

Replacement of the diseased aortic valve is indicated for long-term relief of symptoms and improved survival. Small mechanical valves (sizes 19, 21, and 23 mm) are associated with higher pressure gradients across the prosthesis, which leads to suboptimal cardiac performance.

How do I know if my aortic stenosis is getting worse?

As aortic valve stenosis gets worse, you may have symptoms such as: Chest pain or pressure (angina). You may have a heavy, tight feeling in your chest. Feeling dizzy or faint.

What kind of valve is the aortic valve?

The aortic valve is a valve in the human heart between the left ventricle and the aorta. It is one of the two semilunar valves of the heart, the other being the pulmonary valve. The heart has four valves; the other two are the mitral and the tricuspid valves.

What is aortic gradient?

According Cardiovascular Physiology, stenosis of the aortic valve leads to a pressure gradient across the valve during the time in which blood flows through the valve opening. This aortic valve gradient is expressed as an increase and decrease on each side of the defective valve.

What is a normal aortic root size?

The normal range of aortic root diameters in this group was 17 to 33 mm (mean 23.7). A significant difference (P is smaller than 0.001) in aortic root diameters existed between men and women which could not be explained by differences in body surface area.

Can you live a long life with aortic stenosis?

Patients with aortic stenosis can live full and rewarding lives. However, they may need to be monitored by a heart specialist with office visits and periodic testing. In many cases, aortic stenosis is discovered in patients before they develop any symptoms.
