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

What is the function of heart valve?

What is the function of heart valve?

To direct flow: A heart valve functions to allow unidirectional blood flow. When chambers of the heart contract, one heart valve will open and one will close; this effectively allows only one low resistance pathway for the blood to follow. If there were no valves, blood would flow backwards from where it just came as well as forwards. This would significantly decrease the effectiveness of the heart as a pump. ...Read more

A leaky heart valve at 4 means what?

A leaky heart valve at 4 means what?

Depends: It reallyd depends on the amount of leak thru the valve. An ultrasound called an echocardiogram is one way of evaluation a leaky valve. Other terms used are regurge or regurgitation or insufficiency. A pediatric cardiologist would be very helpful in evaluation the leaky valve. ...Read more

How to repair a damaged heart valve?

Are you a surgeon?: Some heart valves can be repaired. Some can't. Full textbooks and extensive lecture series with demonstrations are devoted to this subject. Most people rely on their doctor who can refer them to a surgeon who is very practiced in this highly technical field. ...Read more

Can you describe what a heart valve is?

Can you describe what a heart valve is?

Yes: Blood moving through the heart is more effecient if it only moves in one direction. Valves open and allow blood to pass through. Then they close and prevent blood from moving backward from where it came. The aortic and pulmonic valves open in systole (during contraction). The mitral and tricuspid valves open during diastole (when the heart is resting and filling). ...Read more

What materials is a heart valve made of?

What materials is a heart valve made of?

Depends: Artificial valves come in two general types - biological and mechanical. Biological valves are usually made from cow or pig tissue. Mechanical valves are made of graphite and metal. Patients on mechanical valves need to be on long term coumadin (warfarin). Not all valves need to be replaced, some may be repaired. Good luck. ...Read more

Can you describe a heart valve malfunction?

Can you describe a heart valve malfunction?

Heart Valve: The heart valves serve a function as a check valve. They direct blood flow in one direction and prevent back flow. Malfunction can be two ways:
1. The valve can be narrowed (stenosis) and restrict blood flow.
2. The valve may not close properly and leak (insufficiency). ...Read more

Which heart valve is most commonly replaced?

Aortic Valve: The most commonly replaced heart valve in the us is the aortic valve. The process of valve disease, usually leading to the tightening of the valve (stenosis) is very similar to that of the development of CAD which is very common in the us. In the developing countries, rheumatic fever in childhood can lead to both mitral and aortic valve disease in the adulthood, but this is not common in the us. ...Read more

What is the significance of a narrowed heart valve?

Stenosis: Blood will have trouble going between heart chambers and great vessels. Depending on the chronicity and the degree of stenosis, bad damage can happen to your lung circulation and your heart chambers. Consequences can be catastrophic. Heart attacks, syncope, heart failure, arrhthmias, sudden death. Common causes are uncontrol htn, congenital bicuspid aortic valve, infections/iv street drugs etc. ...Read more

Could a heart valve repair itself?

Could a heart valve repair itself?

No: If a heart valve is leaky or stenotic these conditions do not generally improve without intervention. This is due to the fact that once abnormal mechanical forces start they can begin a cycle of negative effects. The rate of progression varies tremendously, often related to the root cause. Many people, for example, with trivial leaky valves live normally without ever having any problems. ...Read more

What is the definition of an inflammation of a heart valve?

Endocarditis: The most common type of inflamed heart valve is due to infection, known as endocarditis. This is a life-threatening condition caused by germs, especially bacteria that attack heart valves causing holes, growths, thickening and scarring. This can lead to leaky valves. People with valve disease (except mild mitral valve prolapse without thickening or regurgitation) are at increased risk. ...Read more
