Operative Data (Table 3)
There was no significant difference in emergent cases and IABP use between the groups. Operation time (p = 0.0007) and number of distal anastomoses (p = 0.0003) were significantly higher in the BITA group. Eighty-four patients (94.4%) underwent off-pump CABG successfully. However, 5 patients (5.6%) were converted to on-pump CABG for hemodynamic instability (n = 3), for bleeding (n = 1), and for difficulty of anastomosis because of unfavorable coronary artery anatomy (n = 1). Incomplete revascularization was observed in 11 patients (12.4%) due to a small coronary artery (n = 8), chronic total occlusion of a coronary artery (n = 1), porcelain aorta (n = 1), and patient’s preference for avoiding median sternotomy (n = 1). No significant differences were observed between the groups.
