TCT-605 Introduction of a Novel and Robust Parameter to Quantifiy Coronary Plaque Burden by OCT: Evaluation of Feasibility, Interobserver Analysis and Graphical Illustration of “Luminal Surface Plaque Area”

Methods Plaque assessment consisted of: (a) plaque count of each subtype according to international consensus, (b) plaque volume, (c) luminal surface area was calculated using the Shoelace formula (Fig. left) which determines areas as simple polygons "projected" at the luminal surface, and (d) cap thickness.
