Intravascular optical coherence tomography (OCT) is a valuable imaging tool for guiding percutaneous coronary intervention (PCI). Previous OCT studies have demonstrated that stent abnormalities such as underexpansion, dissection, malapposition, and tissue protrusions are associated with PCI outcomes1. However, the quantitative OCT criteria of those stent abnormalities for the requirement of additional procedures have not yet been clarified. Interventional cardiologists have determined PCI endpoints based on their own experience or local rules in OCT-guided PCI. To standardise OCT-guided PCI, it is necessary to develop quantitative OCT criteria for stent optimisation.
