What Is The Heart Valve In Back Of The Heart Called
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
Chordau tendiniae: The "fibers" are called "chordae" and are similar in function to parachute chords. They prevent the valve leaflets to prolapse (tricuspid and mitral), holding them back just like a parachute chord prevents the parachute from flipping up. If these chords break, the valve will leak. Surgical fixes include annuloplasty (narrowing the valve ring), repairing the chordae, and valve replacement. ...Read moreSee 1 more doctor answer

No, some risks exist: Like any invasive surgical procedure there are risks: infection<2%, stroke < 1%, death<.5%; these numbers can vary depending on degree of co-existing illness in patient. Many of these procedures have been performed, you can obtain success data on a given physician. In every case, a risk/benefit calculation must be analyzed. ...Read moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
