Diffuse stenoses present a unique set of challenges related to accurate vessel sizing in the setting of remodelling, the identification of disease in segments that appear angiographically normal and achievement of optimal stent implantation both in terms of luminal dimensions and stent apposition.

As the absence of a well-defined workflow has likely hampered more widespread uptake of intravascular ultrasound (IVUS) in this setting, this webinar proposes a workflow algorithm that can help support research and clinical decision making.
