We reviewed the data of the isolated coronary artery bypass grafting（CABG）procedures performed in 2015 and 2016, as registered in the Japan Cardiovascular Surgery Database, for preoperative characteristics, surgical outcomes, and the choice of graft material used for the left anterior descending artery（LAD). Isolated CABG was performed off-pump in 55.0%（n＝16,173）of all CABG cases（n＝29,392). The left internal thoracic artery and the right internal thoracic artery were used as the graft materials in 72.1 and 17.4% cases respectively. The operative mortality rates remained unchanged since the last report, with 1.7% for elective cases, 8.8% for emergency cases, and 3.0% overall. In elective cases, the operative mortality rate was 1.1% for off-pump CABG（OPCAB）compared with 2.5% for on-pump CABG. The morbidity rates for all OPCAB cases were significantly better except for those falling in the ‘readmission ＜30 days’ group.
