The purpose of this study was
to analyze our results of mitral valve repair with a rigid
annuloplasty ring (Carpentier-Edwards ring; Baxer-Edwards
CVS Laboratories; Lrvine, Calif) in terms of its efficacy
and safety. We have examined postoperative mitral regurgitation
(MR) and left ventricular diastolic dimension (LVDd) in
63 cases of mitral valvoplasty during a period of 5 years.
The operative methods were 20 cases of tendon reconstruction,
42 cases of quadrangular resection, and 15 cases of annuloplasty
alone. Operative mortality and freedom from complications
were examined at the mean 41.2 months after the operation.
There were no operative deaths, and no case with severe
MR postoperatively. From echocardiographic findings, the
grade of MR changed from 3.13 to 0.28 postoperatively,
and LVDd changed from 58.4±6.71 to 48.7±6.3ml postoperatively.
Reoperation was performed in 2 cases (3.2%) several years
after the first operation. The rate of midterm mortality
was 4.8%. The postoperative mitral valve area was 2.85cm2
in size of 26mm ring, 2.95cm2 in size of 28mm,
3.09cm2 in size of 30mm, which were measured
from PHT (pressure half time) of the Doppler echocardiography.
In conclusion, mitral valve repair with rigid annuloplasty
ring (CE ring) provided good results for MR at midterm
follow-up.
