Abstract

BACKGROUND
We assessed the efficacy of intraoperative intra-aortic balloon pump therapy for achieving hemodynamic instability during off-pump coronary artery bypass surgery. MATERIAL AND METHOD: We studied seven hundred ninety-six patients who underwent off-pump coronary artery bypass between January 2000 and December 2006. The patient were divided into group I (n=39), which received intraoperative intra-aortic balloon pump therapy, and group II (n=757), which did not receive intraoperative intra-aortic balloon pump therapy. RESULT: There were no differences in the operative mortalities (2.6%, 1/39 vs 0.8%, 6/757; p=0.195) and morbidities such as atrial fibrillation (p=0.691), stroke (p=0.908) and mediastinitis (p=0.781) between the 2 groups, although the ventilator support time, the length of the intensive care unit stay and the length of the hospital stay were longer in group I than in group II (p<0.05). Multivariate analysis failed to prove that group I was a high risk group for operative mortality (p=0.549). There were 3 intraoperative intra-aortic balloon pump-related complications in group I (7.9%). However, no longer complications occurred after 2003, when the surgeons began using a smaller sized 8 F catheter that was inserted using a sheathless technique.
CONCLUSION
Intraoperative intra-aortic balloon pump therapy for achieving hemodynamic instability during off-pump coronary artery bypass surgery can be performed safely and it showed comparable clinical results to that of not using intraoperative intra-aortic balloon pump therapy.
