Risk of stent sizing according to the distal MV in LM bifurcation

European Bifurcation Club 2019, EBC 2019 - Barcelona, Spain BENCH & COMPUTATIONAL BIFURCATION STENT SIMULATIONS Risk of stent sizing according to the distal MV in LM bifurcation Author: Yutaka Hikichi, MD, PhD, Saga University, Japan BACKGROUND AND PURPOSE OF THE EXPERIMENT Size selection: according to the distal MB reference? Hypothesis: Stent size influence the acute outcome Implantation methods CONCLUSION When performing a crossover stent to LMT-LAD, the stent size should be selected according to the vessel diameter on the proximal side of the bifurcation. By selecting a larger stent size, the incomplete stent apposition area can be reduced at the LCx ostium after KBT. By doing so, incomplete stent apposition volume can be reduced at the LM-shaft after KBT , and the stent expansion rate can be greatly increased. The risk of injury on the LAD distal side during stent implantation can be reduced by thorough pre- dilatation and devising the stent placement method.
