The Relation Between Optical Coherence Tomography-Detected Layered Pattern and Acute Side Branch Occlusion after Provisional Stenting of Coronary Bifurcation Lesions
Highlights
- • In true bifurcations distal angle and OCT-layered plaque were associated with side branch occlusion.
- • OCT-detected layered plaque was more common in lesions with versus without side branch occlusion.
- • Layered plaques were larger and located toward and proximal to the side branch that then occluded.
Abstract
Background/purpose
Layered pattern (presumed to be healed plaque after a thrombotic event) can be observed by optical coherence tomography (OCT). We sought to assess the ability of OCT-detected plaque composition to predict acute side branch (SB) occlusion after provisional bifurcation stenting.
