초록

1989년 1월부터 1995년 12월까지 27예에서 심장판막 재치환술을 시행하였다. 남자 11예, 여자 16예로 평균연령은 43.51+12.2세 이었다. 기왕의 판막치환은 12예가 조직판막이었고 15예가 기계판막이었다. 인공심장판막이 재치환수술까지 체내에 있었던 기간은 조직판막이 104.91+34.9개월, 기계판막이 55.21+43.7개월이었다. 재치환된 판막은 승모판막 17예, 대동맥판 8예, 삼첨판 1예 그리고 1예는 Cabrol수술을 다시 시행한 경우이다. 재치환의 원인은 조직판막에서 판막의 구조적 결함이 전 예에서 관찰되었으며 그 외에 판막주위누출 2예와 심내막염 1예가 이었다. 기계판막에서는 판막주위조직의 침윤이 8예, 판막주위누출 4예, 판막혈전 3예가 있었으며 판막주위누출 4예중 1예는 Cabrol수술후 인조혈관의 파열이 동반되었다. 술후 합병증(25.9%)으론 창상감염 3예, 미추부 피부괴저 1예, 저심박출증 1예, 심방조동 1예 그리고 방실차단 1예 이었다. 술후 조기사망은 1명이 저심박출증으로 사망하였고 평균 49.5개월간의 추적관찰중 1명이 확장성 심근증으로 수술 3년후에 사망하였다.

From January 1988 to December 1995, 27 patients, 11 men and 16 women, underwent surgical intervention at our institution for prosthetic valve dysfunctions. The mean age was 43.5$\pm$12.2 years. Seventeen(63.0%) patients had the mitral valve replacement, 8(29.6%) the aortic valve, 1(3.7%) the aortic composite graft, and 1(3.7%) the tricuspid valve. Mean follow-up period was 49.5$\pm$30.9 months. In 12 bioprostheses, mean interval between the previous valve replacement and the reoperation was 104.9$\pm$34.9 months. The causes of redo surgery were structural deterioration of the prosthetic valve (12/12, 100%), paravalvular leak (2/12, 16.7%), and prosthetic valve endocarditis(1/12, 8.3%). In 15 mechanical prostheses, the mean interval was 55.2$\pm$43.7 months. The causes of redo surgery were pannus formation (8/15, 53.3%), paravalvular leak(4/15, 26.7%), and valve thrombosis(3/15, 20.0%). Posto- perative complications occurred in 7 patients (25.9%). There was no intraoperative death. But one patient, who received mechanical aortic valve replacement died on the 3rd postoperative day due to low cardiac output and multiorgan failure.
