title: Early Outcomes of Coronary Endarterectomy in Patients Undergoing Coronary Artery Bypass Surgery.
abstract: BACKGROUND
  Coronary endarterectomy (CE) is performed as an adjunct to coronary artery bypass surgery (CABG); however, the efficacy of this technique is still controversial. We aimed to evaluate the impact of CE combined with CABG when compared with isolated CABG.
  
  
  METHODS
  Patients who underwent CABG between July 2007 and June 2014 were included. 70 of 2452 patients (2.8%) underwent CE in addition to CABG. Early results were compared with isolated CABG and predictors of adverse outcome were measured in stepwise multivariate logistic regression analyses.
  
  
  RESULTS
  The incidence of comorbidities including prior myocardial infarction, diabetes mellitus, and three-vessel coronary disease in CE patients was higher; however, mortality (4.3% versus control 3.6%; P = .762) and postoperative complications were not significantly increased in this group of patients (except supraventricular arrhythmia). Although age greater than 70 years, impaired ejection fraction, intraoperative intraaortic balloon pump, and prolonged cardiopulmonary bypass time were important predictors of adverse outcomes, CE was not associated with increased mortality or postoperative morbidities.
  
  
  CONCLUSIONS
  Despite the higher risk profile of patients who underwent CE, this technique was not identified as an independent risk factor for adverse postoperative outcomes.
