Detailed analyses of the configuration of lumina from one hundred (100) segments of severely atherosclerotic epicardial coronary arteries (at least 75 p. 100 of the area of their original lumina narrowed, determined by planimetry) were made. All lumina were distended by a standardized coronary injection technique. In contrast to the general impression, concentric lumina occurred as commonly as eccentric lumina and there were more arteries with an eccentric lumen and/or with significant luminal deformity, i.e. with their smallest diameter smaller than 50 p. 100 of their greatest diameter, than the concentric and more regular ones. The eccentricity and significant deformity of atherosclerotic lumina apparently cause difficulties in precise angiographic measurements of coronary stenosis. To solve the problem of the discrepancies between angiographic and anatomical estimation of coronary arterial stenosis, utilization of more than three different projection angles should be considered in clinical angiographic appraisal.
对100段严重动脉粥样硬化的心外膜冠状动脉（通过平面测量法确定其原始管腔面积至少75%狭窄）的管腔形态进行了详细分析。所有管腔均通过标准化的冠状动脉注射技术进行扩张。与一般印象相反，同心管腔与偏心管腔出现的频率相同，并且与同心且更规则的动脉相比，有更多具有偏心管腔和/或显著管腔变形（即其最小直径小于最大直径的50%）的动脉。动脉粥样硬化管腔的偏心性和显著变形显然会给冠状动脉狭窄的精确血管造影测量带来困难。为了解决冠状动脉狭窄的血管造影评估与解剖学评估之间的差异问题，在临床血管造影评估中应考虑使用三个以上不同的投照角度。
