Coronary collaterals, or “natural bypasses,” are anastomotic connections without an intervening capillary bed between portions of the same coronary artery and between different coronary arteries ( Figure 1 ). 1 Collateral circulation potentially offers an important alternative source of blood supply when the original vessel fails to provide ...
7 de ene. de 2014 · Coronary collaterals are present at birth, with wide interindividual variation in their functional capacity. These vessels protect jeopardized myocardium, and the number of collaterals and...
Cardiovascular disease is the leading cause of death in industrialized countries and may become the most important reason for mortality worldwide. 1 In patients suffering from coronary artery disease (CAD), the size of myocardial infarction mainly determines outcome. 2 Accordingly, the primary strategy to reduce cardiovascular mortality is by sh...
4 de jun. de 2013 · The relevance of these collateral arteries is a matter of ongoing debate, but increasing evidence indicates a relevant protective role in patients with coronary artery disease. The collateral circulation can be assessed by different methods; the gold standard involves intracoronary pressure measurements.
5 de jun. de 2013 · Coronary collaterals are an alternative source of blood supply to myocardium jeopardized by ischaemia. In comparison with other species, the human coronary collateral circulation is very well developed.
11 de ene. de 2007 · Coronary collateral arteries may prevent myocardial ischaemia in healthy subjects and in patients with CHD. A functional collateral circulation may lead to reduced ischaemia, preservation of ventricular function, and an improved prognosis.
4 de jun. de 2013 · The coronary arteries have been regarded as end arteries for decades. However, there are functionally relevant anastomotic vessels, known as collateral arteries, which interconnect epicardial coronary arteries. These vessels provide an alternative source of blood supply to the myocardium in cases of occlusive coronary artery disease.
