Question 1

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

Accepted Answer

See earlier: Please see my earlier answer to the same question.  The papillary muscles are part of the apparatus of the valve, they connect the chordae to the ventricle and support the valve and the ventricle.

Question 2

what are the enlarged muscles in ventricles attached to chordae tendinae?

Accepted Answer

Papillary muscles: The ventricular tissue that give rise to the chordae are often referred to as papillary muscles.

Question 3

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

Accepted Answer

Papillary muscles: The ventricular tissue that give rise to the chordae are often referred to as papillary muscles.

Question 4

what causes papillary muscle dysfunction?

Accepted Answer

Ischemia,: Abnormal mitral valves and lv dysfunction.

Question 5

papillary muscle dysfunction. what makes the murmur?

Accepted Answer

Leaky mitral valve: The murmur is due to intermittent leakage of the mitral valve as a result of papillary muscle dysfunction. Papillary muscle dysfunction is due to myocardial damage or myocardial ischemic.

Question 6

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

Accepted Answer

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.

Question 7

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

Accepted Answer

If the echo is: Normal there really is no papillary muscle dysfunction.

Question 8

what is the function of the chordae tendinae?

Accepted Answer

Close heart valves: The chordae tendineae are cord-like tendons that connect the papillary muscles to the tricuspid valve and the mitral valve in the heart.  These muscles and tendons allow these valves to remain closed against the pressures generated by the contraction of the ventricles.

Question 9

why do the semilunar valves not have chordae tendinae?

Accepted Answer

Pressure: The semilunar valves open and close in response to pressure differentials. Higher pressure in the ventricle forces the valve open and when the pressure drops the valve closes; think of the lid on a trash can as you depress the pedal and you get the idea. The tricuspid and mitral valves require chordae to lock the valves in place so the remain closed when the ventricles generate high pressures.

Question 10

where is the chordae tendinae located?

Accepted Answer

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