Our study and the report by Dohi et al. [1] also suggest less postoperative complications following redo-OPCAB. Others have reported more complications following redo-OPCAB than our study, although still less than the rate observed for the redo-CABG groups. Morris et al. [22] reported 41.3% of postoperative complications after redo-CABG vs 25% after redo-OPCAB (P <0.01), in keeping with the outcome of a small UK study [23].
