Clinical evaluation of St. Jude Medical valve prosthesis with teflon sewing cuff in mitral position

Abstract

a comparative study with dacron sewing cuff-From 1980, the St. Jude Medical (SJM) valve prostheses were implanted in mitral position in 708 adult patients. Before March in 1991, the prostheses with dacron sewing cuff were used in 614 patients. There were 11 cases required reoperation The causes of reoperation in 8 of them were hemolysis and perivalvular leakage. 7 of these 8 cases were suffered prior operation in mitral position. Since March in 1991, the SJM prostheses with teflon sewing cuff were implanted in 94 patients There was no case required reoperation. The postoperative serum LDH level were compaired betueen the cases using dacron cuff and the cases using teflon cuff. There was no significant differencee between them o There might be the better tendency to avoid hemoiysis and perivalvular leakage in the SJM prosthesis with teflon sewing cuff.
