Valve (Overview)

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 leaking back into it.

What is valve disease?

What is valve disease?

Heart valve problems: The heart also has four valves: the tricuspid, pulmonary, mitral, and aortic valves. These valves open and close, acting like doors in the heart, making sure that blood flows correctly from the atria into the ventricles, and then from the ventricles to the rest of the body. Valves can become too leaky, allowing blood to flow backwards, or too narrowed, preventing blood from leaving a chamber. ...Read more

How is a damaged valve fixed?

Depends on problem: Sometimes a valve that doesn't open properly can be helped by opening with a balloon procedure. Sometimes a prosthesis can be passed into the heart via a catheter. Other problems can be fixed by surgically trimming or tightening the valve. In many cases, the best available treatment is to remove the valve and replace it with an artificial valve made from metal, plastic, fabric, or animal tissue. ...Read more

When do they do nothing about leaky valves?

When do they do nothing about leaky valves?

Monitor/Do nothing: With any medical diagnosis, 'doing nothing' is aka monitoring for a defined time and recheck to see if progression occurred. The risk benefit analysis is in favor of monitoring until serious complication is emminent. With a leaking heart valve, dilated heart chamber, decreased exercise tolerance, are watched with echo. Each case is different, so stay in touch with your cardiac team. Be well. ...Read more

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

What is the function of the bicuspid valve?

What is the function of the bicuspid valve?

Mitral valve: Bicuspid means "two leaflets". The only "normal" bicuspid valve in the heart is the mitral valve. It sits between the left atrium and left ventricle. The valve opens to fill the left ventricle during diastole and closes when the ventricle contracts (systole).
The aortic valve is normally tricuspid but some people are born with an abnormal and bicuspid valve which may narrow later in life... ...Read more

Depends: If it is a vegetation of bacterial endocarditis, it will kill you in a few weeks or months unless successfully treated, and may cause a stroke or something else bad in the meantime. If it is a clacified nodule that many middle-aged folks get, it is something to watch and that may be troublesome down the road. ...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

Why does ventricular outlet valves not require chordae tendineae?

Why does ventricular outlet valves not require chordae tendineae?

Different structure: The aortic and pulmonic valves are the ventricular outlet valves. Their shape is different form the ventricular inlet valves. The are a more solid structure with 3 leaflets that close after systole. If you look at google images of the aortic valve and the mitral valve you can see the difference. ...Read more

Is there anything that can be done if valves begin to regurgitate?

Is there anything that can be done if valves begin to regurgitate?

Yes: If your talking about heart valves, yes, those can be repaired through open heart surgery. The severity of the regurgitation, age, and disease burden play a role is deciding an appropriate candidate for surgery. Certain medical centers have less invasive ways of repairing those valves, but it's still a very new and limited technique. ...Read more

How to differentiate between an insufficient and a stenotic valve?

How to differentiate between an insufficient and a stenotic valve?

Exam or Cardiac Echo: Heart valves are occasionally leaky (insufficient) or narrowed (stenotic). Physical exam (auscultation) can lead to the diagnosis by the quality and timing of the heart sounds heard. A cardiac echo (echocardiography) is the common test done to get a picture of the defective valve. ...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
