What is meant by collateral circulation?

This video will explain collateral circulation by Dr. K K Aggarwal, President Heart Care Foundation of India and Group Editor in Chief MEDtalks. Anastomotic channels, also known as collateral vessels can develop in the heart as an adaptation to ischemia. When there is insufficiency of blood flow, the body might try to develop collaterals in the coronary circulation. They serve as conduits which bridges severe stenosis. There are two classes of collaterals: capillary and coronary. Dr. Aggarwal will describe in details both these collaterals.
