Demonstration of Intercoronary Anastomoses in Human Hearts with a Low Viscosity

چکیده
THE EXISTENCE of anastomoses between coronary arteries or between their branches in normal hearts has been a controversial subject for many years.' Fulton2 summarized this controversy in a recent review. As long ago as 1881, Cohnheim and his co-worker3 took the position that coronary arteries are true end arteries without intercommunication. The work of Zoll and his collaborators4 has been widely interpreted as supporting this view. According to these investigators only 9W of hearts free of occlusive coronary artery disease contain anastomoses demonstrable with their technique. In contrast, Gross,5 Laurie and Woods,6 and Bellman and Frank7 have reported that with more suitable techniques bridging channels can be shown to be present in the majority of normal hearts. All are in agreement that in the presence of obstructive arterial disease, anastomoses are readily demonstrable in the great majority of hearts. These anastomoses have been divided by Baroldi and associates8 into two types: (1) intercoronary anastomoses that form bridging channels between different arteries or their branches and (2) homocoronary anastomoses that comprise channels between branches of the same coronary artery. Both forms are of possible functional significance, since both represent pathways by which blood may bypass or circumvent obstructive arterial lesions.

متن کاملCoronary dominance patterns in the human heart investigated by corrosion casting.
OBJECTIVES The aim of this work was to analyze the dominance patterns of the circulation of the human heart, the number of branches from the right coronary artery to the left ventricle, the number of branches from the left coronary artery to the right ventricle and the frequency and location of intercoronary anastomoses. METHODS Casts were made of 25 hearts by the injection of colored acrylic...

متن کاملThe experimental production of intercoronary arterial anastomoses and their functional significance.
Animal experiments were done to learn the degree of coronary narrowing required to produce the larger intercoronary collateral channels, their speed of development, and the degree of protection afforded the myocardium. Twelve or more days of 75 per cent narrowing were required to produce sufficiently rich anastomotic communications to protect the myocardium from damage, and to permit survival a...
