Abstract

Background: To review the middle and long term results of aortic valve replacement(AVR) for 11 years, we surveyed and followed up the patients who underwent AVR. Material and Method: Between Feb. 1986 and May 1997, 134 patients underwent AVR. The patients consisted of 71 men and 63 women whose mean age was 38.9 years, ranging from 17 to 70. Result: The concomitant operations were 62 mitral valve replacement(MVR), 14 MVR + tricuspid valve annuloplasty, 10 Cabrol operation, 16 aortic annulus widening, and so forth. We used 119 mechanical(75 St. Jude Medical, 38 CarboMedics, 6 Sorin) and 15 tissue (Carpentier-Edwards) valves. Early postoperative complications occurred in 35 cases; 9 congestive heart failure, 6 low cardiac output, 5 postoperative bleeding, 5 pleural effusion, and so forth. There were 13 early postoperative deaths(9.7%) due to low cardiac output(5), CHF (2), disseminated intravascular coagulopathy(2), and so forth. The cumulative total follow-up period was 452.7 patient-years with a mean of 3.4${\pm}$3.1 years/patient. There were 9 cases of valve-related complications; anticoagulant-related bleeding(4), prosthetic valve endocarditis(2), thromboembolism(2) and prosthetic valve failure(1) occured at rate of 0.9, 0.4, 0.4, 0.2%/ pt-yr, respectively. Late valve-related death occurred in 3 cases(2.0%/pt-yr) associated with anticoagulant-related bleeding(2) and prosthetic valve endocarditis(1). Conclusion: Actuarial survival rate by Kaplan-Meier method was 91.0${\pm}$4.3 % at 11 years.

배경: 약 11년 동안의 대동맥판막치환술에 대한 중.장기임상성적을 알아보기 위해 대동맥판막 치환술을 시행하였던 환자들을 추적관찰하였다. 대상 및 방법: 1986년 2월부터 1997년 5월까지 134례의 대동맥판막치환술이 시행되었다. 남자가 71명, 여자가 63명이었고 평균 연령은 38.9세였으며 최저 17세에서 최고 70세의 연령범위를 보였다. 결과: 동반된 수술은 승모판치환술(62례), 승모판치환술과 삼첨판성형술(14례), 대동맥륜확대술(16례), Cabrol 술식(10례) 등이었다. 119개의 기계판막과 15개의 조직판막이 치환되었으며 21 mm 이하의 작은 판막이 68례에서 치환되었다. 술후 조기 합병증은 35례에서 발생하였는데 이 중 울혈성심부전 9례, 저심박출증 6례, 술후 출혈 5례, 흉막 삼출액 5례 등의 발생빈도를 보였다. 조기사망은 13례(9.7%)에서 발생하였으며 그 원인은 저심박출증(5례), 울혈성 심부전(2례), 범발성 혈관내 응고장애(2례) 등이었다. 총 추적기간 누계는 452.7 환자-년이었으며 평균 추적기간은 3.4$\pm$3.1 년/환자였다. 판막과 유관한 장기합병증은 9례에서 발생하였는데 항응혈제관련 출혈 4례, 심내막염 2례, 혈색전증 2례, 판막파괴 1례 등이 있었다. 추적기간 중 심장과 유관한 후기 사망은 5례(1.1%/환자-년)에서 발생하였으며 이 중 항응혈제관련 출혈이 2례, 심부전이 2례, 심내막염이 1례였다. 결론: Kaplan-Meier 방법에 의한 11년 보험 통계적 생존률은 91.0$\pm$4.3%였다.
