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.
