[Development of indirect cardiac blood supply after experimental disorders of the coronary circulation].

A reconstruction of the vascular bed was studied experimentally on 70 dogs under various conditions of modelling coronary insufficiency. The data obtained have shown that ligation of basic branches of the left coronary artery results in exclusion of the circulation in wide portions of the myocardium and death of experimental animals. In much lower levels of ligation the resulting disorders are compensated by the development of a bypass vascular bed.
