Optical coherence tomography-guided stent optimization for complex coronary lesions: the OCCUPI trial

Eur Heart JPublished

  • Secondary analysis of the OCCUPI randomised trial
  • as-treated population

Authors' conclusion

The current study identifies long lesions or small-vessel disease as the determinants of stent optimization following OCT guidance, with the achievement of stent optimization significantly associated with improved clinical outcomes.

Study context

Population
Patients with complex coronary lesions who underwent optical coherence tomography (OCT)-guided percutaneous coronary intervention (PCI) with post-stenting OCT evaluationOCT-guided PCI

  • OCT Optimizationn = 549
  • OCT Sub-Optimizationn = 224reference
Primary endpoint

Further findings

Predictors of OCT Sub-Optimization (multivariable)

Long lesions and small-vessel disease were significant independent predictors
