Authors' conclusion

Among patients with complex coronary-artery bifurcation lesions, OCT-guided PCI was associated with a lower incidence of MACE at 2 years than angiography-guided PCI.

Study context

Population
Patients with a clinical indication for PCI and a complex bifurcation lesion on coronary angiography
Participants
1,201 patients
Comparison
OCT-guided PCI vs angiography-guided PCI
  • OCT-guided PCIn = 600
  • Angiography-guided PCIn = 601reference
Primary endpoint
Major adverse cardiac events (MACE):
  • Cardiac death
  • Target-lesion MI
  • Ischemia-driven target-lesion revascularization
Follow-up
Median 2 years
