TIMI myocardial perfusion grade 0

Failure of dye to enter the microvasculature, indicating a lack of tissue level perfusion.

• Intensity Range: 0

Shown below are a static image and an animated image depicting TIMI myocardial perfusion grade 0. The right hand side of both the static and the moving image shows a crescent shaped dark gray area consistent with normal myocardial perfusion of the posterior wall or the circumflex artery territory. In contrast, note that there is little or no corresponding perfusion in the left hand side of the screen in the territory of the left anterior descending artery. Outlined in yellow is the territory that would ordinarily be perfused by the left anterior descending artery and would be as dark as the perfusion in the circumflex territory.
