STENT LONGITUDINAL DISTORSION DURING LEFT MAIN STENTING
Aorto-ostial stent crush during LMCA stenting Exploratory bench findings
Author: Niels Ramsing Holm, Aarhus University Hospital, Denmark
SUMMARY
- The guiding catheter is constrained by the jailed wire and is tracked towards the stent edge
- Regular movements of the guiding catheter during PCI could cause bending and longitudinal compression of the stent. Stent platforms may differ in resistance to distortion
- Early wire exchange after POT may reduce this risk
- Accidental abluminal rewiring during wire exchange may lead to ostial stent crush
- Final Ostial Optimisation Technique may correct guiding catheter induced ostial bending and malapposition of the LMCA stent
