Optimal provisional coronary bifurcation stenting: Final kissing balloon dilatation or not ?
Author: Gerard Finet, MD, PhD, Hospices Civils de Lyon, France
- Quantify the mechanical effects of the POT
- Quantify the differences between:
- FKB approach (with its modified protocols) after POT
- approach with no FKB but consecutive POT with SB balloon inflation (re-POT)
Our preliminary results with 25 fractal bifurcation models with Promus Premier® (Boston) :
- quantitatively validated the mechanical effects of POT
- 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.
