What is the function of the chordae tendinae and papillary muscles?

What is the function of the chordae tendinae and papillary muscles?

Structure o valve: The valve leaflets are tethered by the chordae tendinae and the papilary muscles. The contraction of the papilary muscles then in turn cause movement of teh valve leaflets allowing opening. ...Read more

Muscle (Definition)

It is a body tissue that has the ability to contract. It shortens and generates force. It relaxes and returns to its original length. Muscles move joints, stabilize the body, move air and food through the organs, act as valves for bladder, bowel and other organs. They control movement of the eyes. They help us express ourselves by changing the shape of our ...Read more

What are the enlarged muscles attached to chordae tendinae?

Papillary muscles: The papillary muscles are the muscular attachments of the chordae. These along with the valve leaflets and annuli are the mitral and tricuspid apparati. ...Read more

What are the enlarged muscles in ventricles attached to chordae tendinae known as?

What are the enlarged muscles in ventricles attached to chordae tendinae known as?

Papillary muscle: The papillary muscles attach to the cusps of the atrioventricular valves (a.K.A. The mitral and tricuspid valves) via the chordae tendinae and contract to prevent inversion or prolapse of these valves. ...Read more

Papillary muscle dysfunction. What makes the murmur?

Papillary muscle dysfunction. What makes the murmur?

Papillary muscle: Papillary muscle dysfunction causes abnormality in closing the mitral valve and mitral insufficiency results. ...Read more

My echo says my mitral valve anterior papillary muscle is "prominent." does prominent = hypertrophic? Or would they have said hypertrophic if it was?

Hard to say: Tough to tell. Usually whenever I see that reference it is describing mild thickening or simply a visual impression of an entity slightly more obvious than usual. Obviously without seeing the images I can't be certain, but I would wager it is a simple observation that holds little meaning or significance. That's a gentle way of saying if I were you I wouldn't be concerned. ...Read more

Can papillary muscle dysfunction be present with only a faint murmur, but no symptoms at all, no prior heart attack, normal echo & ekg?

Can papillary muscle dysfunction be present with only a faint murmur, but no symptoms at all, no prior heart attack, normal echo & ekg?

Confusing question: Papillary muscle dysfunction is diagnosed by echo. Therefore one cannot have a normal echo if they have papillary muscle dysfunction. Murmur is present when there is a valvular disease, but faint murmurs may be present with insignificant valvular disease. Such questions as you are asking can be confusing to both patients and the doctors. Ask your doctor to answer these questions for you. ...Read more

What is the function of the chordae tendinae?

What is the function of the chordae tendinae?

Hold valve: Think of valve as a parachute, chordae tendinae are the "ropes" that anchor the valve leaflets or cusps to the heart muscle. Heart muscle contraction pulls on these cords to close the valve, when when heart relaxes then the valve opens. They are an important part of the heart valve apparatus. ...Read more

Why do the semilunar valves not have chordae tendinae?

Why do the semilunar valves not have chordae tendinae?

Not a good answer: You aren't going to like this: it's the way god made them. It is the intrinsic nature of the semilunar valves that they don't have chordae. (it's like asking, why do we have only 2 arms and not 3?). ...Read more

Where is the chordae tendinae located?

Inside the ventricle: Chordae attach the valve to its papillary muscles. They are located on the ventricular side of the valve. ...Read more

Where are the chordae tendinae located?

Where are the chordae tendinae located?

Below: The chordae tendinae are attached to the underside of the tricuspid (right side of the heart between the right atrium and right ventricle) and the mitral valve (left side of the heart between the left atrium and left ventricle). The attach much the same way that the chords of a parachute attach to the chute. The transmit the forces to pull open the valve and align it to close properly. ...Read more

How does a chordae tendinae rupture?

How does a chordae tendinae rupture?

Usually wear & tear: Most cases of chordae tendinae rupture are because of degeneration after years of routine "wear and tear" leads to thickening and retraction. Rarely, it can occur due to infection (endocarditis), either acutely, or later if fibrosis develops and distorts the chorda. If a mitral valve is extremely "floppy", i.e. Mv prolapse, the flopping leaflet may pull the chorda hard enough to tear it. ...Read more

Are the chordae tendinae located in both ventricles?

Yes: These serve as the support "strings" for the mitral & tricuspid valves. ...Read more

What structure does the chordae tendinae hold in place?

What structure does the chordae tendinae hold in place?

The valvular leaflet: The chordae hold the mitral and tricuspid valve leaflets like cords on a parachute. ...Read more

I've been told I have loose chordae tendinae. Could this have been misinterperated on the echo and be something else?

Valve prolapse: Chordae tendenae in a structure that normally exist in every heart,
it is related to 2 of the valves of the heart: the mitral valve and the tricuspid valve
it is like a tendon that connect the undersurface of these valves to a strong muscle, in order to make sure the valve close in the proper line.
diseases of the chordae can make the valve either narrow or loose and leaking in the wrong direction ...Read more

What would damage to the chordae tendinae in the left ventricle result in?

What would damage to the chordae tendinae in the left ventricle result in?

Mitral regurgitation: Damage to the chordae tendinae would result in problems with the closure and sealing of the mitral valve, and would lead to mitral regurgitation, or leaking, and possibly heart failure. ...Read more

What is the result of damage to the chordae tendinae in the left ventricle?

What is the result of damage to the chordae tendinae in the left ventricle?

Heart disease: The chordae are support structures for the mitral and tricuspid valves. When they are damaged, valvar insufficiency results. This can be severe enough to cause congestive heart failure either acute or chronic. ...Read more

What is the consequences of a ruptured chordae tendinae on the right ventrical?

Rupture chordea: It is like an anchor line to fix a tent onto the ground. Chordae rupture makes the valve lose its functional closing effect disrupting efficient pumping effect of the heart. ...Read more

What could happen if the chordae tendinae ruptured in right valve area?

What could happen if the chordae tendinae ruptured in right valve area?

Leaking valve: A rupture of the chordae tendinae of the mitral valve would result in severe leakage so that blood would flow backwards into the left atrium when the ventricle contracts. This would lead to shortness of breath. Fortunately, that is fairly rare. ...Read more

Can you tell me the range of tension that the chordae tendinae exerts during heart pumping?
