Abstract
|
|
|
From June 1984 to February 1994, cardiac valve replacement was performed in 108 patients. The distribution of patients was ranged from 13 to 64 year-old age(mean 39.84*1.24) and 51 patients were male, 57 patients were female(mla:female=1:1.10
64 patients had mitral valve replacement, 27 patients underwent aortic valve replacement and 17 patents were performed double(mitral & aortic) valve replacement. Total 125 artificial cardiac valves were used, mechanical valve were 51 valves and
tissue
were 74 valves.
The duration of follow-up was 473.41 patient-year(mean 4.79*3.29 patient-year) and the information of follow-up was available for 99 patients(92%).
The actuarial survival rates including the operative mortality was 89.5% & 88.3% at postoperative fourth & ninth year. The probability of freedom from overall valve failure, thromboembolism and bacterial endocarditis were 77.5%, 89.2% and 95.6%
at
ninth
year after cardiac valve replacement. (Korean J Thoracic Cardiovas Surg 1994; 27:444-50)
