Toward patient’s left Is this the left or right system? Left system Identify the vessels. Labels are animated in PP - they will appear as you scroll down to allow participants to identify them first. Where is the LMCA? Where is the LAD? Where is the LCX? Where is the OM? What view is this? LAO Caudal - “Spider View” Where should the spine be? Right side of the image in LAO. Difficult to determine here. At which angle should the ribs be? Ribs should mimic the left hand in LAO. Difficult to determine here. Does the vessel have “tendrils”? N/A Is this a “C” or “L” shape?
