Secondary OCT Endpoints * Percentage of stent strut malapposition * Maximum length of segments (mm) with uncovered struts * Maximum length of segments (mm) with malapposed struts * Maximum malapposition distance (mm) * Total malapposition volume * Maximal malapposition volume * Mean neointimal thickeness (strut level) * Percentage of protruding struts per stent * Frequency of Abnormal Intrastent Tissue (AIST) * Stent Volume * Lumen Volume * NIH Volume OCT Indices * NHI (Neointima heterogeneity index) - ratio of maximum neointimal thickness to the average neointimal thickness in each frame. * RUTTS-OCT (Rate of Uncovered To Total Struts in the frame by OCT) Index - The number of sub segments of 2.5mm with uncovered strut/ total number of struts per sub segment (continuous variable and stratified by thresholds >10%, >20%, >30%). * PFU (Percentage of Frames with Uncovered struts) index - the percentage of frames with any uncovered struts per cross-section. * PFM (Percentage of Frames with Malapposition struts) index - the percentage of frames with any malapposition struts per cross-section Quantitative characterization of NIH tissue * Mean Attenuation * Mean Backscatter * Normalized Standard Deviation * Mean Intensity * * width (distance from peak intensity to its half intensity Additional variables (baseline and/or post procedure) * Rates of late acquired stent strut malapposition (matched, FUP vs POST) * Percentage of embedded struts post-procedure * Dissection post procedure behind the stent * Dissection post procedure at stent edges (length, depth) * Qualitative plaque characterization (pre procedure or non-stented segment post procedure) Secondary Clinical Endpoints * Major Adverse Cardiac Events defined as a composite of death, MI (Q wave or non-Q wave), emergent coronary artery bypass surgery (CABG), or justified target lesion revascularization (TLR) by repeat PTCA | — |
