The concept
The concept of this website is based on a previous site that was founded in 2008 and is still up and running. The website is composed as a book, where all sources are properly referenced, according to a good practice in scientific publications.Didn't find a classification?

Coronary artery dissection - NHLBI classification (The National Heart, Lung and Blood Institute)
This classification divides dissection of coronary artery into six types based on their appearance on coronary angiography.
| Type | Description |
|---|---|
| Type A | minor radiolucent areas in the lumen without impairment of flow or persistant dye staining after contrast runoff |
| Type B | luminal flap that is radiolucent and runs parallel to the vessel wall with contrast injection but without impairment of flow or persistant dye staining after contrast runoff |
| Type C | contrast appears outside of the vessel lumen as an "extraluminal cap", the staining appears even after contrast clears off the lumen |
| Type D | spiral radiolucent luminal filling defects, often persistent staining after contast clears from the vessel |
| Type E | new and persistent filling defects in the vessel lumen |
| Type F | lesions that progress to impaired flow or total occlusion |
