    Abstract:
    BACKGROUND: The combination of coronary artery bypass grafting and mitral valve surgeries is closely associated with high in-hospital mortality and morbidity. In this study, we sought to analyze the factors that influence early mortality in 68 patients undergoing coronary artery bypass grafting + mitral valve surgery due to ischemic mitral insufficiency. METHODS: Of 1183 patients undergoing coronary bypass surgery between April 2002 and June 2006, 68 patients (42 male and 26 female) 42 to 78 years of age (mean +/- SD, 59.3 +/- 9.1) underwent mitral valve surgery accompanying coronary bypass surgery (survival, n = 59; mortality, n = 9). The cases were analyzed regarding the demographic, preoperative, and perioperative risk factors that influence mortality. RESULTS: The early mortality rate was found to be 13.2% (9/68) in patients with ischemic mitral regurgitation undergoing simultaneous coronary bypass and mitral valve surgeries. New York Heart Association class > or =3, left ventricle end-systolic volume, left ventricle end-systolic diameter, cardiopulmonary perfusion time, preoperative unstable angina pectoris, intra-aortic balloon application, and age >65 years were determined to be statistically significant risk factors that influence early in-hospital mortality.Conclusion. Surgery, despite having a high mortality risk in patients with ischemic mitral insufficiency, is considered to be a treatment measure that generally improves the quality of life and prolongs life.
