Why does the right atrioventricular valve have three cusps while the left atrioventricular valve has only two cusps?

Why does the right atrioventricular valve have three cusps while the left atrioventricular valve has only two cusps?

Because: because that's the way we evolved. Or, if you'd prefer, that's what God intended. Either way it comes down to tautology: it is what it is, man. ...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

In a normal aortic valve, what stops the valve cusps from opening too much? Or do they just open against the aortic walls?

In a normal aortic valve, what stops the valve cusps from opening too much? Or do they just open against the aortic walls?

Correct to a degree: They are like a parachute and open widely to a maximum length, but not quite to the adjoining wall, of aorta, so there is flow behind to the coronary orifices.
More like a sheet floating in the wind. ...Read more

What are valves in the body and what do they do?

What are valves in the body and what do they do?

4: 4 cardiac valves. 2 atrioventricular and 2 ventriculoarterial. 2 on the right heart 2 on the left heart. Each ventricle has an atrioventricular and a ventriculoarterial valve.They are one way valves. Flow is venae cavae to right atrium, RA to right ventricle via right av valve or tricuspid, rv to pulmonaryartery via
pulmonic valve-lungs-left atrium-mitral valve-left ventricle-aortic valve- aorta. ...Read more

What are the pros and cons of mechanical valve vs tissue valve?

What are the pros and cons of mechanical valve vs tissue valve?

Broadly speaking,: mechanical valves last longer but require oral anticoagulation with warfarin. tissue valves do not last as long, but do not require oral anticoagulation. the decision is a complex one that is best made with the advice of a physician. ...Read more

How does the bicuspid valve function?

How does the bicuspid valve function?

May be normal: The aortic valve is comprised of three leaflets, or cusps, that swing open and closed. Approximately 1% of the population is born with only 2 cups. These swing open and shut in a similar fashion. Depending on the precise architecture of the 2 cusps, there may be increased turbulence of blood flow through the valve, and over time more wear and tear leading to thickening/obstruction, or leaks. ...Read more

How do doctos identify the location of a valve?

The heart valves: don't vary much in location, except un very rare conditions present from birth. Listening with a stethoscope, sound waves (echocardiography) and other imaging (CT scan, MRI) can more precisely locate the heart valves. ...Read more

What happens if someone's bicuspid valve does not close properly?

What happens if someone's bicuspid valve does not close properly?

Aortic insufficiency: When an aortic valve (bicuspid or a normal tricuspid valve) does not close properly, insufficiency or regurgitation ("leaking") results. When mild, this does not have clinical effects, but when severe it can compromise cardiac function. ...Read more

Can i jog in the mornings without damaging my mytral valve further.

Not enough info: Without knowing what is wrong with your mitral valve, it is impossible to say. You need to go see a cardiologist and discuss your cardiac echo (ultrasound that looked at your mitral valve). Ask for a list of exactly what you can and cannot do to keep yourself healthy - don't wait. ...Read more

What is a mitral valve?

What is a mitral valve?

One of 4 heart valve: The mitral valve is one of the 4 heart valves found in the heart. These valves keep blood moving one direction rather than back and forth as the heart contracts. The mitral valve is so named as it looks like the pope's hat (a mitre). The mitral valve separates the left atrium and the left ventricle. ...Read more

Can acupuncture help a leaky valve?

Not technically: It is unlikely that acupuncture will actually make a valve less leaky. It may decrease the symptoms by lowering blood pressure and decreasing anxiety. There are few risks associated with acupuncture- it is generally safe and shouldn't make anything worse. ...Read more

What is the function of mitral valve?

Mitral valve: The mitral valve has to open properly to let blood flow into the left ventricle from the atrium. If it doesn't, we call this stenosis. It has to close to keep the blood flowing toward the body, if it doesn't we call this regurgitation or insufficiency. Either or both problems can exist with the valve if its abnormal. Insufficiency is more common. ...Read more

How can the mitral valve be replaced?

How can the mitral valve be replaced?

Many options: Depending on pts age as well as the characteristics of the valve, there are many options. Mitral valve repair -using the pts own valve and perhapse a ring. Mv replacement-the whole valve is replaced by either a mechnical valve pig valve or a bioprosthetic. Another new technology involves catheter based options such as a clip. All types have pros and cons including possible Coumadin (warfarin) therapy. ...Read more
