ABSTRACT
Objective To analyze the incidence,risk factors,and impact of intraoperative conversion on the mortality in patients undergoing off-pump coronary artery bypass grafting.Methods This retrospective observational study included 207 patients undergoing off-pump coronary artery bypass grafting.According to whether intraoperative conversion,207 patients were randomly divided into intraoperative unchanged group(191 cases)and intraoperative changed group(16 cases).The incidence,patient characteristics,cause of intraoperative conversion,and its impact on outcome were studied.Results Intraoperative conversion increases odds for mortality to 25.0%,while the other group was 1.0%.The most common cause for intraoperative conversion was hemodynamic disturbances during grafting to the obtuse marginal artery.On multivariate logistic regression analysis,left main disease,mitral regurgitation and higher EuroSCORE II independently predicted intraoperative conversion.Conclusion Intraoperative conversion to on-pump coronary artery bypass grafting is independently associated with higher mortality in patients undergoing off-pump coronary artery bypass grafting.Identification of high risk group of intraoperative conversion may improve the outcome.
