[Correction of mitral insufficiency with posterior annuloplasty].
OBJECTIVE
To summarize the experience in treating mitral insufficiency (MI), due to secondary annular dilation in the posterior portion of the annulus with mitral valve reconstruction.


METHODS
Over the past 10 years, we performed mitral valvuloplasty with posterior annuloplasty in 35 patients, of which 27 patients were associated with congenital abnormalities, 3 patients had mild MI, 24 had moderate MI, and 8 had severe MI. Entire posterior annular plication was performed in 7 patients and partial posterior annular plication in 28. Associated subvalvulopasty was performed in 7 patients and leaflets repair reconstruction in 14.


RESULTS
There was no postoperative mortality. Complete correction was achieved in 21 patients (60.0%) and partial correction in 11 (31.4%). Mild and moderate insufficiency was found in 3 patients (8.6%) postoperatively. NYHA function class I was gained in 34 patients. One patient developed pulmonary hypertension and died due to right heart failure five years after operation.


CONCLUSIONS
The results indicate that posterior annuloplasty is a safe, effective technique.
