In patients with MVD and complex lesions, OCT-guided PCI was associated with a lower risk of 1-year MACE than angiography-guided PCI particularly when stent optimisation on OCT was achieved.
Study context
- Population
- Patients with multivessel disease (MVD) (diameter stenosis ≥50% in ≥2 major epicardial coronary arteries) with at least one complex lesion undergoing percutaneous coronary intervention (PCI)patients with MVD among the as-treated population in the OCCUPI trial (n=1604), 575 had single-vessel disease
- Participants
- 985 patients
- Comparison
- Optical coherence tomography (OCT)-guided PCI vs angiography-guided PCI in patients with MVD
- OCT-guided PCIn = 515
- Angiography-guided PCIn = 470
- Primary endpoint
- MACE, a composite of cardiac death, myocardial infarction, stent thrombosis or ischaemia-driven target-vessel revascularisation
- Follow-up
- 1 year
