Overview
Angiographic assessment of apparent collaterals is useful to quantify the angiogenic response to interventions designed to enhance myocardial perfusion and function in ischemic myocardium.[1] [2] [3]. Collateral Circulation is assessed visually using the following grading system:
- Grade 0: No collaterals present. Angiography fails to reveal evidence of collateral vessels.
- Grade 1 (or partial): Minimal collaterals present. Evidence of minimal to partial filling of the recipient branch epicardial arteries/infarct region. It is not necessary for one to see the branches connect directly to the major epicardial artery.
- Grade 2 (or complete): Well-developed collaterals. Evidence of collateral circulation with near complete to complete filling of the recipient major epicardial artery/infarct region.
- Grade 3 (myocardial): Filling of the myocardium by collaterals. If the collaterals are not filling any visible arterial branch, but are only participating in the perfusion of the myocardium.
