Long-term results of valve replacement with the St. Jude Medical valve.

摘要: Between 1980 and 1992, 908 patients underwent single aortic (n =178), mitral = 577), or double =153) valve replacement with the St. Jude Medical at our hospital. There were 392 male 516 female whose ages ranged from 1.2 to 74 years (mean, 52 years). The early mortality rate was 5.0 % (45 patients). A 94 complete follow-up accomplished for 863 who discharged hospital (4682.3 patient-years). Sixty-nine of these died, a late 8.0%. Fifty-two patients, including four thrombosis, had thromboembolic episodes (1.1 / 100 Sixteen (0.3 patient-years) anticoagulant-related hemorrhage, 4 (0.1 /100 prosthetic endocarditis, 11 (0.2%/100 nonstructural dysfunction, 16 (0.3%/100 reoperation. no structural failures in this series. total number valve-related deaths 22. Of those survived, 98 New York Heart Association functional class I II date last follow-up. probabilities freedom thromboembolism hemorrhage 10 94% ± 2 97% replacement, 89 6 92 respectively.
