What are the OCT-identified causes of intrastent restenosis and their impact on clinical outcomes?
Stent underexpansion is a frequent and underestimated cause of intrastent restenosis that is associated with adverse clinical outcomes.
OCT identified neoatherosclerosis and neointimal hyperplasia in comparable proportions. Stent underexpansion was frequent and favored subsequent adverse clinical outcomes.
