BACKGROUND AND AIM OF THE STUDY: We have reported the short- and long-term results of mitral valve replacement in this article. METHODS: Mitral valve replacement was conducted in 276 patients in our clinic between January 1989 and March 2005. The youngest patient was 4 years old and the oldest patient was 74 years old. Mean age was 40.08 +/- 1.06 y. Of these patients, 41.3% were men and 58.7% were women. The reason for operation was mitral stenosis in 96 patients (34.78%), mitral insufficiency in 78 patients (29.26%) and mitral stenosis plus mitral insufficiency in 102 patients (36.96%). The aetiology of mitral valve lesions was acute rheumatic fever in 208 patients (75.36%). The aetiology of mitral valve lesions was degenerative in 37 patients (13.41%), ischaemic in 23 patients (8.33%) and congenital in 8 patients (2.9%). RESULTS: In the 5, 10 and 15-year periods, the actual survival rates were 87.64% +/- 2.02%, 83.35% +/- 2.38% and 68.19% +/- 5.63%, respectively. Thromboembolism was observed in 38 patients (13.77%). The rates of actual freedom from thromboembolism in the 5, 10 and 15-year periods were 93.08% +/- 1.53%, 88.48% +/- 1.99% and 81.06% +/- 3.43%, respectively. Of the 276 patients who had been observed for 15 years, 5 had (1.81%) valvular thrombosis. The rates of actual freedom from valvular thrombosis in the 5, 10 and 15-year periods were 98.89% +/- 0.64%, 98.04% +/- 0.87% and 98.04% +/- 0.87%, respectively. In the 15-year period, 23 patients (8.33%) had haemorrhage due to anti-coagulation. The rates of actual freedom from haemorrhage due to anti-coagulation in the 5, 10 and 15-year periods were 95.64% +/- 1.23%, 93.40% +/- 1.56% and 87.73% +/- 2.96%, respectively. Seven patients (2.54%) had prosthetic valvular endocarditis. The rates of actual freedom from endocarditis in the 5, 10 and 15-year periods were 98.51% +/- 0.74%, 97.60% +/- 0.97% and 97.01% +/- 1.13%, respectively. Nine patients (3.27%) were re-operated. The rates of actual freedom from re-operation in the 5, 10 and 15-year periods were 97.45% +/- 0.95%, 96.58% +/- 1.12% and 96.58% +/- 1.12%, respectively. CONCLUSIONS: St. Jude Medical mechanical valve prosthesis has been the valve of choice in our clinic owing to its excellent haemodynamic properties and low rates of complication. |
