RADIOLOGY Pathways and Functional Significance of the Coronary Collateral Circulation
Two hundred coronary arteriograms and left ventriculograms of patients having significant coronary artery disease were reviewed. Collateral circulation was seen only when the degree of arterial narrowing exceeded 90%. Ten different collateral pathways were noted in patients having right coronary obstruction; seven different pathways were noted in left anterior descending obstruction; five diffe...
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...
متن کاملHistorical Aspects and Relevance of the Human Coronary Collateral Circulation
In 1669, anastomoses between the right and left coronary artery were first documented by Richard Lower of Amsterdam. Using post-mortem imaging, a debate followed on the existence of structural inter-coronary anastomoses, which was not resolved before the first half of the 20 ieth century in case of the presence of coronary artery disease (CAD), and not before the early 1960 ies in case of the n...
متن کاملReappraisal of Functional Importance of Coronary Collateral Circulation
Coronary collateral circulation (CCC) is defined as an alternative blood-conveying circuit to the ischemic myocardium supplied by a jeopardized coronary artery. Accumulating evidence on CCC and its functional role has been derived from basic and clinical studies over several decades. Progress in molecular biology and genetic engineering has enabled us to elucidate the mechanisms of collateral g...
