Data on isolated coronary artery bypass grafting（CABG）performed in 2017 and 2018, 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). Isolated CABG was performed off-pump in 54.6%（n＝14,684）of all CABG cases（n＝26,913), and graft material for the LAD was left internal thoracic artery in 76.4% and right internal thoracic artery in 19.0%. Operative mortality was 1.5% in elective cases（On-pump CABG:ONCAB 1.9%, off-pump CABG:OPCAB 1.2%, p＜0.001), 7.4% in emergency cases（ONCAB 10.2%, OPCAB 4.3%, p＜0.001), and 2.5% overall. Postoperative morbidity was low in almost all aspects in OPCAB, and average JapanSCORE II is elevating every year. Overall short-term operative results for isolated CABG is stable, and operative candidates are shifting to higher-risk patients.
