Objective and methods: Data on isolated coronary artery bypass grafting (CABG) performed in 2013 and 2014, and registered in the Japan Cardiovascular Surgery Database were reviewed for preoperative characteristics, postoperative outcomes, and choice of graft material for the left anterior descending artery (LAD). Results: Isolated CABG was performed off-pump in 54.7% of cases, and graft material for the LAD was left internal thoracic artery in 74.3% and right internal thoracic artery in 15.6%. Operative mortality was 2.0% in elective cases, 8.2% in emergency cases, and 3.0% overall. In elective cases, operative mortality was 1.1% for off-pump CABG compared with 3.0% for on-pump CABG. Conclusions: Clinical results of our isolated CABG were reasonable and acceptable.
