Objective : Comparison with prosthesis mitral valve replacement, mitral valve repair has lots.
of advantages, After valve repair, patients have better left ventricular function, a lower rate of thrombo
embolism and infective endocarditis. The authors studied early experience of mitral valve repair.
Materials and Methods : From January 2000 to May 2002, 43 consecutive patients with mitral
regurgitation had mitral valve repair. Valve disease was degenerative in 51.2 per cent, ischemic in 18.7
per cent, rheumatic in 13.9 per cent, infectious in 11.6 per cent, and others in 4.6 per cent. Surgical
techniques included P2 quadrangular resection (n = 13; 30.95%), chordal tranfer (n = 11; 26.19%), only
= = =
annuloplasty (n 10; 23.8%), artificial chordae (n 3; 7.14%), commissural closure (n 3; 7.14%), and
others in 2 cases (4.76%)
Result : Immediate post-operative echocardiogram showed no or trivial regurgitation in 95
per cent and moderate regurgitation in 5 per cent. There was no operative mortality, but 1 case had
hospital mortality with 1-24 months follow-up, 90 per cent of cases had FC. I and the other ( 10%) were
in FC II.
Conclusion : This preliminary experience provided promising immediate and early result.
The authors believe that mitral valve repair is safe and seems to have a much better result than mitral
valve replacement. However, a randomized control study and long-term follow-up, in the future, are
important.
