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.
