[Anatomical and coronary angiography data on coronary anastomosis].
Beyond two series of heart studies (anatomical with 150 hearts treated by injection-corosion method, and angiographic with 211 coronarography 3 days after a heart attack) the authors have noticed 92 coronary anastomosis with: 28 right homolateral 22 left homolateral 42 contralateral The existence of these anastomosis has been confirmed by coronarography of 30 out of 173 patients having a significant lesion of the artery responsible for the heart attack. The authors noticed also that these anastomosis are effective when the coronary system is deficient and the supplies are ensured by the other artery. The study permits to distinguish two groups of functional collateral: the functional collateral spontaneously observed during coronarography recruitable collaterals which are ready to be functional in case of main coronary artery obstruction.
