Spontaneous Coronary Artery Dissection Type 2B

Case 1

Type 2B SCAD lesion is observed in the left anterior descending artery. (projection view: 41 RAO, 19 CRA)

Spontaneous Coronary Artery Dissection Case Studies

Type Feature Example
Type 1
  • Pathognomonic multiple radiolucent lumen
  • Contrast dye staining of arterial wall
  • Presence or absence of dye hang-up or slow contrast clearing from the lumen
The unnamed parameter 2= is no longer supported. Please see the documentation for {{columns-list}}.
2
Type 2
  • Diffuse (typically >20–30 mm)
  • Smooth narrowing varying in severity (ranging from 40 to 100% stenosis)
  • No response to intracoronary nitroglycerin
  • No atherosclerotic lesions in other coronary arteries
  • Repeat coronary angiogram showing spontaneous resolution of the dissected segment or previous angiogram showing normal artery
  • Intracoronary imaging with OCT or IVUS proving the presence of intramural hematoma and double-lumen
The unnamed parameter 2= is no longer supported. Please see the documentation for {{columns-list}}.
2
2A variant Normal arterial caliber proximal and distal to dissection
2B variant Dissection extends to the distal tip of the artery without discernible normal segment distally
Type 3
  • Mimics atherosclerosis with focal or tubular stenosis
  • Lack of atherosclerotic changes in other coronary arteries
  • Long lesions (11–20 mm)
  • Hazy stenosis
  • Linear stenosis
  • Note: requires OCT or IVUS to prove the presence of intramural hematoma or double-lumen
The unnamed parameter 2= is no longer supported. Please see the documentation for {{columns-list}}.
