    Stent type identification with optical coherence tomography: novelty in search of clinical application

    Over the last three decades, developments in intravascular ultrasound (IVUS) and optical coherence tomography (OCT) have advanced our understanding of coronary disease pathophysiology and improved outcomes of percutaneous coronary intervention (PCI) procedures. Although in daily clinical practice most imaging utilisation relies on a simple, two-dimensional display of cross-sectional coronary images, real-time three-dimensional (3D) visualisation of coronary arteries with OCT offers advantages over and above simple vessel sizing and plaque characterisation. Fourier domain OCT, with superior axial (10-15 µm) and lateral (20-40 µm) resolutions and a faster image acquisition rate (180 scans/second), as well as quicker pullback speeds (18 .
