6.4 Ruptured chordae tendineae

Rupture of the chordae tendineae is a condition which has been reported relainfrequently, but it is an important complicating factor in a significant proportion of cases with MR and some animals with TR. Rupture of MV chordae tendineae is much more common and more significant than TV chordae tenrupture and may be immediately life-threatening. Rupture of the chordae tendineae is likely to result from degenerative disease affecting the whole of the valve, rather than being a primary problem. Frequently, however, animals have been known to have pre-existing cardiac disease. In the author's experience, the right commissural cusp of the MV is most frequently affected, although other leaflets can be involved. Ruptured chordae tendineae are recognised with greater frequency since the advent of echocardiography.
