Abstract
Considering the lack of consensus on optimal treatment method for moderate IMR, we conducted the present study. It aims to determine whether a concomitant MV surgery during CABG improves clinical outcome in moderate IMR patients.
In this study, we comparatively-studied the course of un-repaired moderate mitral regurgitation after CABG alone, versus CABG with MV surgery, in order to assess the impact of un-repaired moderate ischemic mitral regurgitation on the immediate and early outcome of CAD patients undergoing standard CABG using CPB.
This study population encompassed 100 CAD patients complicated by moderate IMR who underwent CABG with (group I, no 50) or without mitral valve surgery(group II, no 50). As regard functional status, The majority of patients in our study were in NYHA class II-III. In group I, 16 patients (32 %) had NYHA Class II and 17 patients (34 %) had NYHA class III. In group II, 19 patients (38 %) and 13 patients (26 %) had classes II and III respectively. Values were statistically- insignificant. Both groups are matched regarding (age, gender, NYHA classifications, smoking, and presence of diabetes, hypertension and dyslipidemia,obesity ,previous MI and PCA) basic demographic and clinical characteristics. There were statistical insignificant differences between both groups in laboratory results as p value>0.05.
Preoperative echo parameters showed statistical insignificant differences between bothgroups as p>0.05. group I had significantly longer duration of CBP and aortic class time than group II with statistical significant differences (p<0.05). Also, group I had higher percentage of use of intra-aortic balloon
