European Bifurcation Club 2019, EBC 2019 - Barcelona, Spain NEWS 2 After Single Crossover stenting; “KBT or not KBT”, that is the question. Routine KBT is always necessary?

LCx ostium itself might be independently associated with high restenosis rates. The fact may be partially explained by unique anatomical feature; “hinge motion”, twitching and bending. LMT PCI results could be hampered with high restenosis rates in LCx ostium; however the incidence may not be directly associated with fatal prognosis.
