Abstract

Between May 1986 and May 1996, 269 patients underwent prosthetic valve replacement. A bioprosthetic valve was replaced in 70 cases and mechanical valve was replaced in 232. Of this 12 patients performed reoperations for replacement, and the mean interval between primary valve operation and reoperation was 87.6 months for mitral valve and )7.7 months for aortic valve. There were 10 women and 2 me , agcd from 22 to 68 years(mean 45). A bioprosthetic valve was implanted in 8 cases and a mechanical valve was implanted in 4 cases for initial operation. llidications for reoperation were structural deterioration in 5 cases(42%), valve thrombus in 5 cases(42%) and endocarditis in 2 cases(17%). Operations performed included 3 aortic valve replacements(25%), 9 mitral valve replacements(75%). Wc used mechanical valve in llcases(92%) and tissue valve in 1 case(8%) for reoperation. There were 2 early operative deaths because of valve detachment and of acute respiratory failure. Among ten survivor's, there were no late deaths with follow up of 35.8 months.

1986년 5월부터 1996년 5원까지 총 269명(조직판막70례, 금속판막 232례)의 판막 치환술 환자중 판막의 재치환술이 필요했던 12례를 분석 하였다. 승모판 재치환술이 9례, 대동맥 판막 치환이 3례로 연령범 위는 16세에서 68세까지로 50대 이후가 가장 많았다. 초인공판막치환후 재 수술이 필요했던 숭모판막의 경우 평균 87.6개월, 대동맥판막의 경우 36.7개월로서, 대부분의 경우 운동시 호흡곤란이 주증상이었으며 원인으로서는 판막자체의 구조적 실패 5례, 심내막염 2례였으며 재치환술에 사용된 판막은 기계판막 11례, 조직판막 1례로 수술후 사망률은 17% (2/12)였고 술후 심내막염 및 폐렴에 의한 호흡부전으로 사망하였다.
