The role of extra- and intracardial collateral circulation in patients with ischemic heart disease

The article reviewed the research on the functional role of the collateral circulation (intra- and extracardiac anastomoses) of the heart. The role of intracardiac collaterals in patients with acute coronary syndrome in the acute period and in patients who have to undergo coronary bypass surgery is investigated. An inverse correlation between the presence of intracardiac collaterals and signs of the development of myocardial infraction in patients with acute coronary syndrome has been revealed. It was shown that extracardiac vasculature formed due to aseptic pericarditis is determined by selective angiography of HAV. It is also an additional source of myocardial blood supply.
