Optimal provisional coronary bifurcation stenting: Final kissing balloon dilatation or not ?

Author: Gerard Finet, MD, PhD, Hospices Civils de Lyon, France

 

OBJECTIVES

  1. Quantify the mechanical effects of the POT
  2. Quantify the differences between:
    1. FKB approach (with its modified protocols) after POT
    2. approach with no FKB but consecutive POT with SB balloon inflation (re-POT)

CONCLUSION

Our preliminary results with 25 fractal bifurcation models with Promus Premier® (Boston) :

  1. quantitatively validated the mechanical effects of POT
  2. showed by comparison with :
    • FKB alone
    • and POT + FKB with symmetric or asymmetric balloon inflaOon pressure thatwithre-POT with SB dilation provides the best mechanical results and is the simplest technique in 1-stent bifurcation strategy.
    • SBO almost free of strut (4.9%)
    • a very low rate of global strut malapposition (2.6%)
    • an almost perfect morphology of the carena and the wall facing the SB ostium
    • a maintained circular cross-sectional area of the MoV (relative elliptic ratio : 1.0)
    • the almost perfect respect of the linear law of coronary artery bifurcation geometry (0.66)

We are completing these preliminary results with 25 other fractal bifurcation bench models with Ul#master® stent (Terumo)
A total of 50 experimentations in fractal bifurcation bench models.
