Balloons and stent sizing for bifurcation PCI Role of Intra-coronary Imaging

European Bifurcation Club 2019, EBC 2019 - Barcelona, Spain CORONARY BIFURCATION IMAGING Balloons and stent sizing for bifurcation PCI Role of Intra-coronary Imaging Author: Yoshinobu Murasato, MD, PhD, Kyushu Medical Center, Japan TAKE HOME MESSAGES Device sizing (general): EEL-based reference diameter measurement is firstly recommended. In case of invisible EEL, lumen-based measurement is also available. For the optimal stent landing zone, it is important to avoid dissection, > 50% plaque burden, and lipid pool. Device sizing: bifurcation lesion POT and KBI balloon should be selected according to vascular branching law. In the bifurcation lesion, Finet’s law is applicable for imaging-guide reference diameter measurement, not for angio-based one. Stent should be selected considering maximal expansion capacity. Minimum expansion index considering vascular branching and tapering is more physiological to select post-dilation site and appropriate balloon.
