Abstract
The improved success rate of recanalization of occluded coronary arteries is partly due to the development of the retrograde approach via collateral pathways. The proper application of this technique requires a thorough knowledge of the anatomy of the coronary collateral system, and its functional capacity. Furthermore, proper angiographic technique is required to highlight the collateral pathways and understand the challenges when trying to pass wires through these channels.
