Abstract

Objectve To analyze the risk factors of perioperative mortality after mitral leaflet repair retrospectively.Methods Data of 542 patients undergoing mitral leaflet repair in An Zhen Hospital between March 1985 and June 2006 were collected.Preop- erative and operative variates were evaluated by univariate and multivariate logistic stepwise regression analysis,Results 20 patients (3.7 %)died postoperatively within 30 days.Univariate risk factors included age,preoperative congestive heart failure,preoperative left ventricular end-systolic diameter,preoperative left ventricular ejection fraction,NYHA class Ⅲ-Ⅳ,CPB time,Cross-clamp time and mltral leaflet repair concomitant coronary artery bypass graft(CABG).Logistic stepwise regression analysis showed that preopera- tive congestive heart failure,preoperative left ventrieular ejection fraction and mitral leaflet repair concomitant CABG were independent risk factors of mortality after mitral leaflet repair.Conclusion Conclusion It suggests that preoperative congestive heart failure,preo- perative left ventricular ejection fraction and mitral leaflet repair concomitant CABG are independent risk factors for mortality after mi- tral leaflet repair.

二尖瓣小叶修复术后围手术期死亡率的危险因素分析

目的回顾性分析二尖瓣小叶修复术后围手术期死亡的危险因素。方法收集1985年3月至2006年6月在安镇医院行二尖瓣修复术的542例患者的资料。结果20例(3.7%)患者术后30 d内死亡。单因素危险因素包括年龄、术前充血性心力衰竭、术前左室收缩期终末内径、术前左室射血分数、NYHA分级Ⅲ-Ⅳ、CPB时间、交叉钳夹时间、中侧小叶修复合并冠状动脉旁路移植术(CABG)。Logistic逐步回归分析显示，术前充血性心力衰竭、术前左室射血分数和二尖瓣瓣修复合并冠脉搭桥是二尖瓣瓣修复术后死亡的独立危险因素。结论术前充血性心力衰竭、术前左室射血分数及二尖瓣瓣修复合并冠状动脉搭桥是二尖瓣瓣修复术后死亡的独立危险因素。
