Guiding coronary stent implantation

Although percutaneous coronary intervention (PCI) is most commonly guided by angiography alone, results from a new study investigating adjunctive imaging modalities showed that the use of a novel optical coherence tomography (OCT)-based stent sizing strategy results in similar minimal stent area (MSA) compared to intravascular ultrasound (IVUS)-guided PCI. Imaging-guided PCI (with both OCT and IVUS) also resulted in improved stent expansion and acute stent-based procedural success compared to angiography-guided PCI.
