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 are a static image and an animated image depicting TIMI myocardial perfusion grade 0.
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
