Figure 5. Angiographic features of spontaneous coronary artery dissection.

Figure 5

A, Type 1, multiple radiolucent lumens (arrow) or arterial wall contrast staining. B, Type 2, diffuse stenosis that can be of varying severity and length (dissection starting from arrow). C, Type 3: focal or tubular stenosis (arrow), usually <20 mm in length, that mimics atherosclerosis. Intracoronary imaging should be performed to confirm the presence of intramural hematoma or multiple lumens. D, Optical coherence tomography in type 3 (C) shows intramural hematoma (asterisk).
