Variability in coronary arteriogram readings was studied by having cine films 10 patients read by 11 readers. Of the 11, 3 subsequently met as an expert panel to provide a joint evaluation which could serve as a standard. Considerable variability was found between individual readers and between readers and the panel. The average SD for estimation of any segmental stenosis by any single reader was 18%. Disagreement about the number of major vessels with a 70% stenosis occurred 31% of the time. Discrepancies occurred most in analyzing distal arterial segments, in reading nonopacified segments and during analysis of films showing more severe disease or having poorer technical quality. Recent experience in reading arteriograms seemed to be the most important characteristic in determining the accuracy of a reader. A protocol for the use of 3 readers was suggested.
