dc.description.abstract[한글]배경 및 목적: 승모판막 수술후 뒤늦게 발생하는 삼첨판막 폐쇄부전의 빈도와 예측인자를 알아보고자 하였다.방법 및 결과: 1992년부터 1995년 사이에 승모판막 수술을 받은 334 명의 환자를 대상으로 후향적 연구를 하였다. 삼첨판막 폐쇄부전의 평가는 심초음파를 이용하였고 평균 추적관찰 기간은 10.3±2.1 년 이었다. 전체환자중 약 70%가 수술 후 약10년째 심초음파를 시행하였다. 의미있는 뒤늦은 삼첨판막 폐쇄부전은 128명(38.3%)에서 관찰되었고, 이들은 삼첨판막 폐쇄부전이 없는 환자들에 비해 나이가 많았고(47±14 vs 44±12yrs, p=0.040), 심방세동이 더 흔했으며(89 vs 62%, p<0.001), 좌심방이 더 심하게 확장되어 있었고(59±13 vs 56±11mm, 0.015), 평균 우심방압이 더 높았으며(12±9 vs 8±5mmHg, p<0.001), 심장판막수술을 과거에 받았었던 경우가 더 많았고(46 vs 31%, p=0.005), 수술전부터 삼첨판막 폐쇄부전을 가지고 있었던 경우가 많았다(35 vs 14% p<0.001 ). 로지스틱 회귀분석에 의하면 뒤늦은 삼첨판막폐쇄부전의 독립적인 예측인자는 수술전 심방세동(Odds ratio 4.55; 95% C.I. 1.88-11.0; p=0.001), 수술전 삼첨판막 폐쇄부전(Odds ratio 2.29; 95% C.I. 1.08-4.84; p=0.03), 그리고 수술전 높은 평균 우심방압(Odds ratio 1.07; 95% C.I. 1.01-1.13; p=0.014) 으로 나타났다.또한 뒤늦은 삼첨판막 폐쇄부전이 나타난 경우 그렇지 않은 경우에 비해 심장혈관질환 관련 예후가 나쁜 경향이 있었다.결론: 승모판막 수술후 뒤늦게 나타난 삼첨판막 폐쇄부전은 비교적 흔하며 예후가 좋지 않다. 또한 수술전 심방세동, 의미있는 삼첨판막 폐쇄부전, 높은 평균 우심방압이 독립적인 예측인자임을 알 수 있었다. [영문]Background: We investigated the incidence and predictors of development of significant tricuspid regurgitation (TR) late after mitral valve surgery.Methods and Results: A retrospective analysis was performed on a total of 334 patients who underwent mitral valve surgery between 1992 and 1995. Development of late TR was evaluated in the echocardiographic examination with a mean follow-up duration of 10.3±2.1 yeas. Seventy percent of study population completed ten-year echocardiographic follow-up. Significant TR was found in 128 patients (38.3%). Patients with late TR showed advanced age (47±14 vs 44±12yrs, p=0.040), a higher prevalence of atrial fibrillation (89 vs 62%, p<0.001), a greater left atrial dimension (59±13 vs 56±11mm, 0.015), a higher mean right atrial pressure (12±9 vs 8±5mmHg, p<0.001), a more frequent prior history of valve surgery (46 vs 31%, p=0.005), and a higher prevalence of preoperative TR (35 vs 14% p<0.001 ). In multivariate analysis, preoperative atrial fibrillation (Odds ratio 4.55; 95% C.I. 1.88-11.0; p=0.001), preoperative TR (Odds ratio 2.29; 95% C.I. 1.08-4.84; p=0.03), and preoperative mean right atrial pressure (Odds ratio 1.07; 95% C.I. 1.01-1.13; p=0.014) emerged as independent determinants for the development of late TR. Patients with late TR showed lower survival rate free from cardiovascular events than those without TR.Conclusions: Development of TR late after mitral valve surgery is common and associated with poor prognosis. Preoperative atrial fibrillation, TR and mean right atrial pressure were identified as independent predictors.-
