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.
