UNLABELLED: From March 1989 to July 2000, 82 patients have received the aortic-mitral replacement in our hospital. Among these patients, 11 patients had left ventricular ejection fraction less than 40%. We evaluated the mortality, the cause of death, postoperative complications and mid-term results of these patients. Five-years' survival rate was determined by means of the Kaplan-Meire method. Follow-up was complete for 100% of the patients.
RESULTS: One patient (9%) died on 7 days after operation, due to multiorgan failure. Postoperativery, all patients had anticoagurant therapy with warfarin sodium and showed improvement in functional class. Mean follow-up was 3.4 years (0-5.9 years). The late death rate was 20% (2 patients). But there were no valve-related deaths during the follow-up periods. Overall survivals rate at 5 years was 70%.
CONCLUSION: Despite the poor left ventricular function, we obtained satisfactory mid-term results of mitral-aortic valve operations.
