Abstract
St. Jude Medical bileaflet valve was implanted in 42 patients from September, 1988, to July, 199)(mitral valve replacement in 25, aortic valve replacement in 11, multiple valve replacement in 6). Concomitant procedures were performed in 5 patients(11.9%). The early mortality was 4.8%(2 patients) and the late mortality was 9.5%(4 patients). The valve-related causes of late mortality were prosthetic valve endocarditis(threi), unknown(one). There was no instance of structural failure. Follow up was 100% complete, with 179.8 patient-years and a mean follow up of 54 months(from 1.5 to 84 months). The overall actuarial survival rates was 90$\pm$4.7% at 5 years. At 5 years, the acturarial freedom from valve failure was 90$\pm$4.7%, 89.7$\pm$4.5% from thromboembolism and 92.3 $\pm$4.2% from bacterial endocarditis, respectively.
저자들은 1988년 9월부터 1993년 7월까지 42례의 환자(승모판막치환 25례, 대동맥 판막치환 11례, 중복판막치환 6례)에서 St. Jude Medical 판막치 환술을 시행하였다. 판막치환수술과 다른 수술을 동시에 시행한 예는 5례(11.9%)있었다. 조기사망율은 4.8%(2례)였고 만기사망율은 9.5%(4례)였다. 수술 후 생존자를 대상으로 총 179.81환자-년의 추적이 이루어졌으며 평균 추적기간은 54개월이었고 추적률은 100%이었다. 판막과 관련된 만기사망원인으로는 심내막염이 3례, 원인을 밝히지 못한 경우가 1례 있었다. 판막의 구조적 실패와 이로 인한 합병증으로 사망한 례는 없었다. 5년에 전체 환자의 생존율은90$\pm$ 4.7%였고 판막실패없는 빈도는 90$\pm$4.7%, 혈전색증없는 빈도는 89.7$\pm$4.8%, 심내막염없는 빈도는 92.3 $\pm$4.2%였다.
