- OCT guidance for PCI in true unprotected left main coronary artery bifurcation lesions was clinically feasible, with high success rates for pre- and post-stenting pullbacks.
- Visibility of the LMCA ostium was limited by factors such as short pullbacks, insufficient clearance, or guide catheter shadowing.
- No statistically significant difference in major adverse cardiac events (MACE) was observed between OCT-guided and angiography-guided groups.
- OCT guidance showed a non-significant reduction in MACE, aligning with the effect estimate from the main OCTOBER trial.
