Question 1

what is the definition or description of: aortic valve?

Accepted Answer

Exit door of heart: The aortic valve is one of 4 valves in the heart, each of which separates 2 cardiac chambers. It opens when blood is actively ejected from the left ventricle into the aorta artery, to be carried to the rest of the body. It then closes firmly to prevent blood from flowing backwards, while it passively continues to flow forward to body's vital organs.
When next heartbeat comes, it opens again.

Question 2

what is the definition or description of: bicuspid aortic valve?

Accepted Answer

Abnormal heart valve: A bicuspid aortic valve is a condition that is present from birth. The aortic valve doesn't form normally, resulting in a narrowing of the valve. This narrowing causes the heart to work harder to pump blood, which can cause heart problems in the long term. People with bicuspid aortic valves usually require valve replacement surgery at some point in their lives. Bicuspid valves run in families.

Question 3

what is the definition or description of: aortic valve replacement?

Accepted Answer

Replacing valve: The patients aortic valve leaflets are cut out and a prosthetic valve is sewn to the patients aortic valve annulus. It is done using cardiopulmonary bypass. Choices of valve are mechanical or bio prosthetic.

Question 4

where is the aortic valve located?

Accepted Answer

Aortic Valve: The aortic valve is an integral part of the heart and is located between the left ventricle and the aorta. It opens when the left ventricle contracts (systole) and allows blood to be pumped into the aorta. It closes when the left ventricle fills (diastole).

Question 5

what is another name for aortic valve?

Accepted Answer

None: I am not aware that the aortic valve has another name.  I have heard described as a semilunar valve.  That is more of a description than a name.

Question 6

what are the symptoms of aortic valve insufficiency?

Accepted Answer

Shortness of breath: If valve insufficiency is mild or moderate, you may not have any symptoms. Severe valve insufficiency causes significant back flow of the blood causing enlarged heart chamber and congestion of blood to structure before the valve (lung or liver) causing shortness of breath and heart failure symptoms.

Question 7

is the aortic valve operation dangerous?

Accepted Answer

It depends: A heart valve operation, like any procedure has risks and benefits.  The task is to determine the risk vs. Benefit of the said procedure and proceed with the proper action.  So, while a heart valve operation may have some risk associated with it, leaving a patient in need of the said operation maybe the less safe thing to do.  Your cardiologist and ct surgeon would be the best judges of this.

Question 8

which type of valve is the aortic valve?

Accepted Answer

Tricuspid: The aortic valve is in the heart separating the left ventricle and the aorta.  It is usually a tricuspid (three leaftlet) valve that opens as the heart pumps blood out of the heart and closes as the heart relaxes and fills with blood before the next beat.  It keeps blood flowing in the correct direction.  Conditions affecting the aortic valve are narrowing (stenosis) or leakage (insufficiency).

Question 9

what is the mechanism of the aortic valve?

Accepted Answer

Think swinging gate: The aortic valve is like a gate situated at the exit of the heart, that needs to swing open every time blood is ejected from the heart, and then needs to shut tight after ejection, preventing backflow of blood into the heart while it is relaxing. It is comprised of 3 cusps, like the doors of a gate, which swing outward simultaneously, and then come back to swing shut.

Question 10

what is a replacement of the aortic valve?

Accepted Answer

AVR: Exactly what it says. If there is a problem with the aortic valve (between left ventricle and aorta) (either narrowed -stenotic- or leaking -insufficient) it can be surgically replaced. It can be replaced with a mechanical "metal" or tissue valve "pig valve".
