Abstract
Procedural guidance with intravascular ultrasound (IVUS) imaging improves the clinical
outcomes of patients undergoing percutaneous coronary intervention (PCI) by: 1) informing
the necessity for lesion preparation; 2) directing appropriate stent sizing to maximize
the final stent area and minimize geographic miss; 3) selecting the optimal stent
length to cover residual disease adjacent to the lesion, thus minimizing geographic
miss; 4) guiding optimal stent expansion; 5) identifying acute complications (edge
dissection, stent malapposition, tissue protrusion); and 6) clarifying the mechanism
of late stent failure (stent thrombosis, neointimal hyperplasia, stent underexpansion
or fracture, or neoatherosclerosis). Optical coherence tomography (OCT) provides similar
information to IVUS (with some important differences), also potentially improving
acute and long-term patient outcomes compared to angiography-guided PCI. The purpose
of this review is to describe the similarities and differences between IVUS and OCT
technologies, and to highlight the evidence supporting their utility to improve PCI
outcomes.
