    IVUS-Guided Percutaneous Coronary Interventions: An Ongoing Odyssey?

    Coronary angiography falls short in accurately delineating anatomy of epicardial vessels as it provides only a two-dimensional visualization of the lumen. Moreover, angiographic lesion assessment is impeded in cases of diffuse disease of reference vessels, lesion foreshortening and eccentricity as well as overlap of several arterial branches. Conversely, intravascular ultrasound - a sound wave based technology - provides superior spatial resolution of 80-150 μm and extends diagnostic information enabling more precise assessment of lumen and vessel wall dimensions including atheroma burden and vessel remodeling.
