Abstract

This repot reviews the angiographic and intravascular (IVUS) assessment of coronary bifurcation lesions. Overall, bifurcation lesion anatomy and morphology is critical for technical decision making, and a key factor for successful bifurcation PCI. Optimal viewing is essential for proper angiographic assessment, especially for evaluation of the degree of SB involvement. Current classifications based on the presence or absence of significant angiographic stenosis within the three segments of the bifurcation anatomy may not provide sufficient anatomic and morphologic information to guide technical decision making. Dedicated 2D bifurcation quantitative coronary angiography with segmental analysis of the bifurcation provides greater accuracy for quantification of the degree of stenosis in the PV and especially the SB ostium. IVUS assessment at preprocedure provides valuable information regarding vessel size, and plaque morphology and distribution (particularly in relation to the SB ostium) that may help select treatment strategy. At postprocedure, IVUS imaging evaluates stent apposition within the stented segment(s) and the appropriateness of stent expansion particularly at the SB ostium, what may impact long-term outcomes.
