Abstract
CBLs comprise up to 20% of lesions treated with PCI. The anatomy also makes PCI more challenging, and rates of MACE following PCI are much higher compared to non-bifurcation lesions. Treatment requires an understanding of lesion characteristics, stent design, and therapeutic options. In bifurcation lesions, coronary angiography cannot accurately visualize the carina area due to overlapping the MV and SB, limiting the accurate assessment of atherosclerotic involvement. On the contrary, IVUS or OCT is useful in guiding the PCI strategy by offering helpful preprocedural information such as lumen and vessel dimensions and lesion characteristics during PCI. Furthermore, Imaging-guided PCI could provide more favorable outcomes than angio-guided PCI by allowing optimal expansion and apposition of the stent as well as its appropriate landing zone.
