When does the aortic valve close in the heart?

When does the aortic valve close in the heart?

During diastole : The aortic valve open to let the blood out of the left ventricle and into the aorta (the main vessel of the body) during systole (when the ventricle contracts) and closes in diastole to prevent regurgitation of the blood from the aorta back into the left ventricle. During this time the blood is moving from the atria and filling the ventricles. ...Read more

Valve (Definition)

A valve is a structure that regulates the direction of flow. The heart is a special kind of pump. It moves blood by squeezing and relaxing. There are 4 chambers and each chamber has a valve. This keeps blood from moving backwards when the heart squeezes. When a chamber squeezes it lets the blood move forward but when the chamber is relaxed it prevents the blood from ...Read more

Which direction does the aortic valve pump in the heart?

Which direction does the aortic valve pump in the heart?

Out: The heart muscle, specifically the ventricles contract or "pump". When the left ventricle contracts, propelling blood out of the heart, the aortic valve opens allowing blood to exit the heart. The blood travels from the heart in your great artery called the aorta. ...Read more

Does heart depend on the condition of aortic valve in regurgitation?

Yes: The aortic valve(the valve that leads from the left ventricle to the rest of the body), if that valve leaks then the blood that was to go out to the body is coming back into the heart. A new batch of blood is entering in to the lv from the left atrium across the mitral valve , and this needs to go through the aortic valve to the rest of body. The lv has to work twice as hard and fails over time. ...Read more

I have aortic valve stenosis. Is lifting 10lb dumbbells bad for my heart and valve?

I have aortic valve stenosis. Is lifting 10lb dumbbells bad for my heart and valve?

Depends: It really depends on the severity of your aortic stenosis. If it is mild and you have no symptoms then exercise should not be a problem. However if it is severe and you have symptoms then i would not recommend exercise until you have recovered from your aortic valve surgery. Your best resource is your doctor who can actually examine you. ...Read more

Men, 85 years old.Narrowing of the aortic valve in the heart.Valve area 0.8cm2,42mmhg。he is normal, no pain , no nothing.How long does he can live?

Depend on symptoms: This is a severe aortic stenosis as per valve area and the gradient across the aortic valve. You need a cardiovascular surgeon evaluation. Most common symptoms chest pain, fatigue, shortness of breath, syncopes. Your age is not a contraindication for surgery. A less invasive procedure is a trans catheter aortic valve replacement (tavr). If you are symptomatic the risk of death increase. ...Read more

With a bicuspid aortic valve is it normal to feel your heart have a spasam then feel like it stops for a couple seconds then start beating like normal?

BAVD is the most : Common congenital heart defect affecting adults. Aortic valve have 2leaflets instead of 3. With time the valve will become nonfunctional due to calcium deposits. Symptoms of chest pain, dizziness or fainting, shortness of breath, palpitations depending on type of damage( stenosis vs regurgitation). You may be having premature ventricular contractions. I will recommend cardiology eval asap. ...Read more

My mom is 85 and 18 months ago had heart failure due to a leaky aortic valve & af how long will the valve last? & what's going to happen?

Valve replacement?: If she had a new valve implanted, it will last her the rest of her life. If not, her candidacy for valve replacement will depend on her general health, other illnesses, and motivation. Heart failure due aortic regurgitation is ominous, especially in view of her age. CHF can be treated with medications but will eventually get worse. Af requires anticoagulation and control with medication ...Read more

Will COPD and heart problems compound the symptoms and make them worse. I have stage 1close to 2 COPD and aortic valve insufficiency + irreg. Heartbea?

Will COPD and heart problems compound the symptoms and make them worse. I have stage 1close to 2 COPD and aortic valve insufficiency + irreg. Heartbea?

Yes: COPD and aortic valve regurgitation, if significant enough, can both make you short of breath. Working harder to breathe secondary to copd, or the volume overload of a leaky aortic valve can both increase your likelihood of atrial arrhythmias, . ...Read more

Aortic Valve (Definition)

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 ...Read more


Aorta (Definition)

The aorta is the largest artery in the body, leaving directly from the left ventricle of the heart to supply blood to the entire body. It is made of elastic tissue layers called "intima" and is subject to damage by high blood pressure, smoking, cholesterol, ...Read more
