Coronary arteriography; method of presentation of the arteriogram report and a scoring system.

A coronary arteriographic report presentation consisting of a diagram on which the radiologist draws the coronary arterial anatomy of each individual case is described. The diagram allows a clear visual presentation of all the information gained from the analysis of the original arteriographic study including anatomical variations, the position and importance of each artery in terms of the myocardium it supplies, the sites and severity of obstructions and the presence of collateral pathways. A myocardial scoring system which expresses the severity of left ventricular arterial obstructive disease is also presented. The myocardial score takes into account not only the degree of stenosis of any number of arterial branches, but also their importance in terms of the amount of myocardium supplied.
