| ==Overview==

| The appearence of irregular lesions with intraluminal filling defects and contrast staining may indicate a fissured atherosclerotic plaque with adherent thrombus.<ref name="Davies-1991">{{Cite journal | last1 = Davies | first1 = SW. | last2 = Marchant | first2 = B. | last3 = Lyons | first3 = JP. | last4 = Timmis | first4 = AD. | last5 = Rothman | first5 = MT. | last6 = Layton | first6 = CA. | last7 = Balcon | first7 = R. | title = Irregular coronary lesion morphology after thrombolysis predicts early clinical instability. | journal = J Am Coll Cardiol | volume = 18 | issue = 3 | pages = 669-74 | month = Sep | year = 1991 | doi = | PMID = 1869729 }}</ref>

| ==Definition==
| |
| A stenosis is classified as having '''irregular contour''' if the vascular margin is rough or has a "sawtooth" appearance.<ref name="Ellis-1990">{{Cite journal | last1 = Ellis | first1 = SG. | last2 = Vandormael | first2 = MG. | last3 = Cowley | first3 = MJ. | last4 = DiSciascio | first4 = G. | last5 = Deligonul | first5 = U. | last6 = Topol | first6 = EJ. | last7 = Bulle | first7 = TM. | title = Coronary morphologic and clinical determinants of procedural outcome with angioplasty for multivessel coronary disease.

| ==Grading of Lesion Irregularity==
| |
| | |
| * Grade 0: Smooth – no irregularity.
| |
| * Grade 1: Mildly Irregular – lesion has an indistinct lumen edge.
| |
| * Grade 2: Sawtoothed/Grossly Irregular – lesion has defined jagged or “sawtoothed” lumen edges.
