Key result
Off-pump CABG in the ROOBY trial had a 12.4% intraoperative conversion rate to on-pump CABG, which the author argues reflects surgical inexperience rather than true procedural inferiority.

The ROOBY trial's comparison of on-pump versus off-pump CABG is criticized for a fatal flaw regarding the surgeons' lack of experience with the off-pump technique.
Puskas et al. (2010) conducted a letter in Coronary artery disease requiring CABG (n=2,203). Off-pump CABG vs. On-pump CABG was evaluated on Intraoperative conversion from planned off-pump CABG to on-pump CABG. Off-pump CABG in the ROOBY trial had a 12.4% intraoperative conversion rate to on-pump CABG, which the author argues reflects surgical inexperience rather than true procedural inferiority.
