![]() Outlined with a yellow dashed line is the pathway that the dye would have filled in case the stenosis was absent.Ĭlick here for other examples of TIMI flow grade 0. Outlined in blue in the second image is the flow of the dye which completely stops at the level of the stenosis. Shown below are an animated image and a static image depicting TIMI flow grade 0 in the RCA. There is no antegrade flow beyond the point of occlusion. TIMI Grade 0 flow is defined as no perfusion.
