Description
Objectives
The aim of the study was to identify the predictors of side branch (SB) compromise in severely calcified bifurcation lesions treated with orbital atherectomy (OA).
Background
SB compromise remains a major complication of bifurcation lesion percutaneous coronary intervention (PCI). Higher prevalence of lipid‐rich plaques and spotty calcification by optical coherence tomography (OCT) and SB ostial stenosis by angiography have been previously suggested as predictors of SB occlusion after main vessel (MV) stenting.
Methods
Patients with chronic stable angina and severely calcified bifurcation lesions, in whom provisional stenting strategy was planned, were enrolled in the study. OA was used for lesion preparation in all cases. OCT imaging of the MV was performed before and after stenting. SB compromise was defined as a composite of SB occlusion (TIMI flow grade ≤ 2) and SB intervention …
