Abstract During the coronary bifurcation intervention procedure, imaging including intravascular ultrasound and optical coherence tomography is essential to provide precise anatomy of the lesion and morphological information. This consensus document between the Korean Bifurcation Club and the Japanese Bifurcation Club summarizes practical guidelines and current evidences on lesion assessment, device selection, procedural guidance, and the optimization of bifurcation intervention by the imaging.

Introduction Percutaneous coronary intervention (PCI) for bifurcation lesions remains challenging because of a relatively low success rate, high incidence of procedural complications and inferior clinical outcomes compared to those in nonbifurcation lesions; even in the new-generation drug-eluting stent (DES) era [1]. In bifurcation lesions, coronary angiography cannot accurately visualize the carina area due to overlapping of the main vessel (MV) and side branch (SB), Kensuke Takagi, Ryoji Nagoshi and Byeong-Keuk Kim have equally contributed on the article as first author. * Soo‑Joong Kim [email protected] * Yoshinobu Murasato [email protected] 1
which might limit the accurate assessment of atherosclerotic involvement. On the contrary, intravascular imaging including intravascular ultrasound (IVUS) or optical coherence tomography (OCT) is useful in guiding the PCI strategy by offering helpful pre-procedural 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. In this first consensus document between the Korean Bifurcation Club (KBC) and the Japanese Bifurcation Club (JBC), we include a scientific 6
