Characteristics of stent thrombosis in bifurcation lesions analyzed by optical coherence tomography: insights from the national PESTO French registry
Author: Nicolas Amabile, MD, PhD Cardiology Department Institut Mutualiste Montsouris, Paris, France
AIM
The present work aimed to investigate the characteristics, mechanisms and relative incidences of bifurcation lesions ST among a large cohort of patients explored by OCT.
CONCLUSION
- In this prospective ST registry, bifurcation lesions were involved in 17.5% of the cases.
- An underlying mechanical abnormality was identified in 91% of the cases that mostly involved PMB.
- There was no significant difference between underlying mechanical abnormalities in bifurcated vs. non- bifurcated lesions ST, except for neoatherosclerosis.
- Malapposition was the leading potential cause for ST.
- Stent underexpansion was less frequently observed in case POT and/or final KBI was applied during index PCI.
