Ischaemic mitral valve regurgitation: a surgical approach.
The aim of this study IS to determine surgical results after surgical mitral valve repair in ischaemic mitral regurgitation.


METHODS
Between January 1999 and June 2000, 64 patients (5.1% of overall patients) underwent myocardial revascularization and mitral valve surgery. A Cosgrove-Edwards mitral annuloplasty ring was used in 59 cases (92.2%). Average patient age was 64.3 +/- 12.4 years (38 males, 21 females). Average degree of mitral regurgitation was 2.8 +/- 0.6. Average NYHA class was 3.5 +/- 0.5. Average ejection fraction (EF) was 40 +/- 12.5 percent.


RESULTS
Post-operative 30-day mortality was 3.4% (2 patients). The follow-up was complete for 95 percent (mean 20.4 +/- 4.8 months for patients) and data showed an improvement of NYHA class (mean value 1.8 +/- 0.2) (p = 0.01) and ejection fraction (mean value 51.7 +/- 10.2) (p = 0.05) with residual mitral regurgitation value of 0.6 +/- 0.7.


CONCLUSIONS
Mitral valve repair in coronary artery disease improves left ventricular function, quality of life and survival rate with low operative risk. Perioperative transesophageal echocardiography has a central role in surgical decision making.
