Abstract

Results of surgical treatment for ischemic mitral regurgitation were retrospectively analyzed in 209 patients. All patients underwent myocardial revascularisation as well as mitral valve surgery. Preoperative myocardial infarction was registered in 75% of cases. These patients had different degrees of left ventricular dysfunction. Postoperative 30-day mortality was 4.3% for the whole group but higher in patients with lower ejection fraction. Looking at preoperative values of ejection fraction (EF), long term follow-up of 75 months, there is a statistically significant differences in survival rate (p < 0.05), freedom from cardiac decompensation (p < 0.05), and other complications (p < 0.001), but only comparing two subgroups of patients, those with preoperatively ejection fraction lower and higher than 20%. Early postoperative, and especially long term results, are better in patients with higher ejection fraction. According to our experience, it is possible to predict the results after surgery for ischemic mitral regurgitation, depending on the degree of preoperative left ventricular dysfunction.
