The TIMI grade that indicates complete perfusion corresponds to which number?

• A. 3
• B. 0
• C. 1
• D. 2

Answer: (A)

TIMI flow grading describes how well blood reaches the distal coronary bed after reperfusion. It ranges from no perfusion to normal, antegrade flow. Complete perfusion means the distal bed is fully filled with normal flow, with no delays or occlusion impeding it. That level is the highest grade on the TIMI scale, and it signifies successful reperfusion. The other grades describe progressively worse perfusion: no perfusion beyond the occlusion, penetration with minimal distal flow, and delayed or partial distal perfusion. So complete perfusion corresponds to the top TIMI grade.
