title: Transabdominal off-pump coronary artery bypass grafting using the right gastroepiploic artery.
abstract: BACKGROUND
  : Anastomosis of the right gastroepiploic artery to vessels of the inferior wall of the heart can be performed using a transabdominal approach without sternotomy and without cardiopulmonary bypass.
  
  
  METHODS
  : From July 1999 to December 2004, 18 patients presenting with only right coronary artery disease were operated on by the transabdominal approach using a pedicled right gastroepiploic artery graft. In 14 patients, it was a redo operation. In all redo patients, a patent graft to the anterior wall was present. Median EuroSCORE was 5 (range 1-13). The right descending posterior artery was grafted in 10 patients, the right coronary artery in 8 patients.
  
  
  RESULTS
  : There was no hospital mortality and no conversion to sternotomy. Hospital morbidity consisted only of a right pleural hemothorax and a superficial wound infection. No blood transfusion was necessary in 16 (89%) patients. Hospital stay averaged 6 days.Follow-up is complete and averaged 2 years (range 0.5-5.5 years). There was no late mortality. Seventeen patients (94%) were asymptomatic. One patient who experienced return of angina 1 year after the procedure underwent a percutaneous transluminal coronary angioplasty of the right coronary artery. Thirteen patients underwent a stress test at median follow-up of 14 months without signs of myocardial ischemia.
  
  
  CONCLUSIONS
  : Off-pump coronary bypass grafting using a right gastroepiploic artery by the transabdominal approach is a safe and effective procedure with a low hospital morbidity and excellent follow-up. In redo operations, this technique excludes the risk of damaging patent grafts to the left coronary system.
