- New analysis challenges previous studies on multi-arterial grafting (MAG) over single-arterial grafting in coronary artery bypass procedures.
- No significant difference in long-term survival based on surgeon preference rather than traditional as-treated analyses.
- Reanalysis using surgeon preference as an instrumental variable showed no significant difference in long-term survival between patients treated by surgeons who frequently performed MAG versus those who primarily used SAG.
- Findings should not discourage MAG procedures, recognizing the need for individualized clinical acumen in deciding on the optimal conduit strategy for each patient.
- Authors suggest future research to apply the surgeon-preference approach to younger patient cohorts using STS data.
