Stent cell sizes: Important data for bifurcation stent selection (EuroIntervention, Accepted for publication)
Author: Peter Mortier, MD
LIMITATIONS
- Real-life bifurcations have a much more complex geometry
- The criterion is too strict in case of stents partially deploying within the side branch
- Stent selection depends on a large number of aspects and cell size is just one of them (e.g. closed cell design may provide better scaffolding)
CONCLUSION
- Cell sizes
- Stent cell sizes differ considerably
- The proposed criterion helps to select stents which have cells that can be sufficiently enlarged
- However, this does not guarantee optimal strut positioning
- Virtual tools
- Computer models can accurately predict stent deployment/distortion
- These models may help to investigate different bifurcation stenting techniques
- Such models provide a platform to design and to optimize dedicated bifurcation stents
