Coronary artery ulceration is assessed visually using a well defined grading system. Grade 0 corresponds to no angiographic evidence of ulceration, grade 1 ulceration is present when the lesion contains a neck with contrast material dissecting under the plaque either proximally or distally, and grade 2 ulceration is present when there is distinct extravascular extravasation of contrast material with the appearance of a mushroom. | Coronary artery ulceration is assessed visually using a well defined grading system.

Overview
Coronary artery ulceration is assessed visually using a well defined grading system. Grade 0 corresponds to no angiographic evidence of ulceration, grade 1 ulceration is present when the lesion contains a neck with contrast material dissecting under the plaque either proximally or distally, and grade 2 ulceration is present when there is distinct extravascular extravasation of contrast material with the appearance of a mushroom.
Examples
Grade 0
Grade 0: No angiographic evidence of ulceration
Shown below is an animated image depicting a normal RCA with no evidence of ulceration.
Grade 1
Grade 1: The lesion contains a neck with contrast material dissecting under the plaque either proximally or distally
Shown below are an animated image and a static image depicting grade 1 ulcerated coronary lesion. Note the presence of a "neck" within the lesion.
Grade 2
Grade 2: Distinct extravascular extravasation of contrast material with the appearance of a mushroom
Shown below are an animated image and a static image depicting grade 2 ulcerated lesion. Encircled in yellow in the image on the right is the ulcerated lesion which has a "mushroom" appearance.
