What can cause the rupture of chordae tendineae leading to the acute MR ?
|Dr. Yasser Mokhtar - Sun Feb 09, 2003 9:55 pm||
Thank you very much for using our website.
The mitral valve apparatus is composed of mitral annulus, leaflets, chordae tendineae and papillary muscles.
Acute mitral regurgitation caused by acute damage of the mitral valve can be caused by several reasons including:
- Ruptured chordae tendineae whether because of mitral valve prolapse or not.
- Papillary muscle rupture or malfunction from a heart attack.
- Infection of the valve by bacteria.
- Trauma to the valve apparatus itself.
In cases of mitral valve prolapse, the abnormality is thought to be secondary to some kind of a degenerative process.
In cases of mitral valve prolapse, rupture of the chordae tendineae is more common in males over 50 years who actually have chronic mitral regurge and this leads to worsening of their already present mitral regurge.
Once more thank you very much for using our website https://doctorslounge.com and if you still have any questions do not hesitate to ask them.
Yasser Mokhtar, M.D.
