STENT LONGITUDINAL DISTORSION DURING LEFT MAIN STENTING
Stent longitudinal distortion during left main stenting prevention and treatment conclusion
Author: Olivier Darremont, Clinique St Augustin, Bordeaux, France
CONCLUSION
On OCT, findings of Longitudinal stent deformation are:
- Cross-section: Stacked (overlap), Overhanging struts, Malapposition, unequal distribution of struts and disrupted stent circularity
- Longitudinal assessment: Shortening of stent length
- 3D-reconstruction is useful to judge stent distortion/ deformation
- In general, OCT is very accurate in stent length measurement (Accuracy -0.13%, precision 5.86%), so that it is reliable to evaluate longitudinal shortening of stent (>10%).
- Due to the engagement of catheter in LM, stent deformation in proximal LM may be overlooked on OCT.
