OCT vs Angiography

OCT-guided PCI Improved Procedural Outcomes and Safety Results compared to Angiography-Guided PCI as Demonstrated in ILUMIEN IV1, OCTOBER2

ILUMIEN IV

ILUMIEN IV is the largest global imaging randomized clinical trial with n=2,487 patients in 80 global centers. The trial compared OCT-guided stent implantation vs. angiography guided in high-risk or complex lesions. Primary endpoint was achieving larger post-PCI lumen dimensions and improving clinical outcomes.

OCTOBER

OCTOBER trial was conducted in 38 heart centres across 13 European countries with n=1,201 patients randomized in a 1:1 ratio to undergo OCT-guided or angiography-guided PCI of bifurcation coronary lesions. A step-wise protocol was use in the OCT arm; in the angiography arm, intravascular ultrasound use was discouraged but could be pursued for left main (LM) PCI.

The primary endpoint was major adverse cardiac events (MACE), defined as a composite of cardiac death, target lesion myocardial infarction (TL-MI), and ischemia-driven target lesion revascularization (ID TLR), after two years.

 

KEY RESULTS:

OCT-guided PCI of complex bifurcation lesions is superior to angiography-guided PCI for major adverse cardiac events 2 years3

  • MACE @ 1 year:
    (10.1% vs 14.1%, p=0.035)
  • Cardiac death:
    1.4% vs. 2.6% (HR 0.53, 95% CI 0.22–1.25)
  • ID TLR:
    2.8% vs. 4.6% (HR 0.60, 95% CI 0.32–1.13)
  • TL-MI:
    7.8% vs. 8.5% (HR 0.90, 95% CI 0.60–1.34)

Watch Dr. Johnson demonstrate how to apply OCT-guidance to a complex bifurcation case from a participant in the OCTOBER Trial with a highly challenging left main stent.

Additional body of evidence in support of OCT-guided PCI

Multiple other studies of OCT-guided PCI vs. angiography alone suggest that intravascular imaging with OCT is associated with better clinical performance3,5,7
