[noun]

Aortic valve

[NOUN]

a heart valve that regulates the flow of blood from the left ventricle to the aorta, the largest artery in the body

What is "aortic valve"?

The aortic valve is located between the left ventricle and the aorta, and it consists of three cusps or leaflets. When the left ventricle contracts, the aortic valve opens, allowing oxygenated blood to be pumped into the aorta. Once the ventricle relaxes, the aortic valve closes to prevent the backflow of blood into the ventricle. This closure creates a one-way flow of blood, ensuring proper circulation and distribution of oxygenated blood to the body's tissues and organs. The aortic valve plays a crucial role in maintaining the efficiency and integrity of the cardiovascular system.

Examples

1. What would be the size of the aortic valve?

2. It has a funny tri-lobal shape at the bottom, which contains the aortic valve.

3. So just quick overview of the study design, we have 466 cases of bicuspid aortic valve, which doesn't seem like a lot, but again, this hasn't really been studied in large numbers before and we selected controls from the MGI biobank.

4. And the catheter has a little balloon on the end that's about four millimeters, and we inflate that balloon to open up the aortic valve tissue.
