Spontaneous Coronary Artery Dissection Cases

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}}. 2
