collateral blood flow

Web In the heart collateral vessels can help to supply blood flow to ischemic regions caused by stenosis or occlusion of epicardial arteries. Web While coronary collaterals provide substantial blood flow to the resting heart they are often insufficient during increased myocardial oxygen demand for example.
