Overview
In TIMI Grade 5 thrombus, a recent total occlusion is present. [1]
The characteristics of a recent total occlusion are:
- There is often a beak like appearance of the occlusion. Chronic occlusions tend to have a more abrupt or straight appearance.
- The clot has not propagated backward to the most distal branch.
- Some collaterals may be present, but usually there are not extensive collaterals.
Example
Shown below are an animated image and a static image depicting TIMI grade 5 thrombus in the RCA. Outlined in yellow in the image on the right is the beak like appearance of the occlusion.
