title: Left anterior descending artery revascularization in low-risk patients: early outcomes after off-pump versus on-pump surgery.
abstract: OBJECTIVE
  This study aimed to compare the early outcomes of off-pump and on-pump myocardial revascularization in patients with stenosis in the left anterior descending artery (alone or with diagonal artery disease).
  
  
  METHODS
  We retrospectively reviewed the medical records of 300 patients: 150 who underwent on-pump coronary artery bypass and 150 who underwent off-pump coronary artery bypass grafting. There were no significant differences between the 2 groups with respect to medical data and operative findings. On-pump and off-pump groups were compared in terms of mortality and morbidity within 30 days of the operation.
  
  
  RESULTS
  Hospital mortality was 3.3% (5 patients) in the on-pump group and 2.6% (4 patients) in the off-pump group. Five patients (3.3%) in the on-pump group experienced myocardial infarction; 3 died of cardiogenic shock. Four patients (2.6%) in the off-pump group experienced myocardial infarction, and 2 of these patients died. Two patients (1.3%) in the on-pump group and 2 patients (1.3%) in the off-pump group experienced stroke; 1 patient in each group died. One patient (0.6%) in the on-pump group had mediastinitis and died of sepsis.
  
  
  CONCLUSIONS
  Among low-risk patients (defined according to EuroSCORE criteria) who underwent left anterior descending coronary artery bypass, the results obtained with the on-pump and off-pump methods showed no significant differences with respect to morbidity or mortality.
