TIMI myocardial perfusion grade 0
Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]
Overview
Failure of dye to enter the microvasculature, indicating a lack of tissue level perfusion.
- Intensity Range: 0
- 0.5 = Minimal ground glass appearance (“blush”) or opacification of the myocardium in the distribution of the artery. Minimal blush is being defined as being either very small in size and/or being less intense or bright than “normal” blush.
- Intensity Range: 0.5
- Note - If no blush is present, the Qualitative Blush Analysis will all be “DNA=Does Not Apply” except for “Total Frames Elapsed in which Blush is Present” which would be “0”, “Total frames in Cinerun” and the venous system assessments.
Example
Shown below is an example of TIMI myocardial perfusion grade 0 in right coronary artery without subtraction. Note that the myocardium is pale in contrast to TIMI myocardial perfusion grade 3
