[HSF] MV Repair Failure

[Ajit Damle]

Ani, and Forum members,

Can you quote the references for these?
1. Incidence of MR after repair
2. Re-operation after repair
3.Rosk factors for these.

Thanks!

Ajit

I don't think your recurrences are an inordinate number, but the fact is
that the ordinate number is not insignificant. We have to come clean about
this when counselling patients for degenerative mitral valve repair - the
reality is at least 20% will have recurrent MR within 10 to 15 years. At
least this is what all the best available data show. If you do not know of
any recurrences, they are either undiagnosed or simply not being brought to
your attention. In the Mayo series remember over half were due to
progression of natural disease which is invariable in some patients.
 
 
In the fibroelastic deficiency case, however, i would argue that sliding
plasty should not be a tool to allow a more aggressive resection but rather
if one needs a sliding plasty in fibroelastic disease for the purpose of
achieving reapposition then it means the resection was too excessive. The
solution is not sliding plasty but not to over resect. If tissue is limited
in P1 and P3 the resection should probably be minimal (even triangular)
resecting part and not al of P2 and if the residual reapposed leaflet is
unsupported then it can be resuspended with other means (chordal transfer or
gortex). Remember that if you read Jebara's original paper on sliding
plasty, the whole essence was to prevent SAM by reducing leaflet height and
not to allow more aggressive resection.
 
Dr Adams still plicates the annulus but is doing much less resection and
plication than he used to - he now believes that the end result probably
matters much more than the means used to achieve it, which is a change in
thinking since our last mitral course. The proviso however is that the end
results meet the essential Carpentier principles of restoring geometry and
adequate surface of coaptation, so I would not say he is any less
Carpenterian!
