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

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
