Abstract
In the period from May, 1980, to June, 1988, 624 St. Jude Medical valve prostheses have been implanted in our hospital. During this period we have experienced 12 cases of hemolytic anemia immediately after operation. Then we have studied about hemolysis after SJM prosthtic valve implantation and compared with Bjork-Shiley and Carpentier-Edwards valve. In acute period LDH values after SJM valve implantation was higher than that of BS and CE valve. There were no clinical hemolysis in chronic period. LDH values after double valve replacement was higher than that after single valve replacement. Massive blood transfusion, residual aortic regurgitation, valve orientation and preoperative liver dysfunction were thought to be risk factors of hemolytic anemia.
