  • Slide 26 - Coronary Angiography Distal Blood Flow/Collateral Classification Based on TIMI Trial TIMI Grade Contrast Flow 0 (No perfusion) Antegrade flow to lesion; no flow beyond occlusion 1 (Penetration with Contrast passes beyond minimal perfusion) lesion but does not opacify distal vessel during cine run 2 (Partial perfusion) Contrast passes obstruction and fills distal vessel.However, rate of filling and/or washout slower than vessel segments outside lesion 3 (Complete perfusion) Contrast passes freely into distal at same visual rate as unaffected adjacent vessels
  • Slide 27 - Coronary Angiography Distal Blood Flow/Collateral Classification Based on TIMI Trial Collateral Supply Contrast Flow 1 Absent 2 Minimal 3 Well developed Adapted from TIMI
  • Slide 28 - Coronary Angiography NHLBI Classification System for Coronary Dissection Dissection A Small radiolucent area within the lumen of the vessel B Linear, nonpersisting extravasation of contrast C Extraluminal, persisting extravasation of contrast D Spiral-shaped filling defect E Persistent lumen defect with delayed anterograde flow F Filling defect accompanied by total coronary occlusion Length (in mm) Measure end to end for type B through F dissections Staining Persistence of contrast within the dissection after washout of contrast from the remaining portion of the vessel
