The authors describe the value of the caudal left-anterior-oblique view in visualizing the following arteries: left main coronary, proximal circumflex, early-arising first marginal, proximal left anterior descending, first diagonal, and anomalous septal perforators from the circumflex system. The technique involves movement of the parallelogram (x-ray tube--image intensifier combination) to the left 55-65 degrees and caudal angulation of 15-20 degrees. To promote additional profiling of the left coronary system, imaging is performed after full expiration. In our series of 100 patients, this view is indispensable in determining significant pathology in the arteries of the proximal left coronary system.
左冠状动脉主干、近端回旋支、早期发出的第一钝缘支、近端左前降支、第一对角支以及来自回旋支系统的异常间隔穿支。该技术包括将平行四边形（X射线管 - 影像增强器组合）向左移动55 - 65度，并进行15 - 20度的尾位成角。为了更好地显示左冠状动脉系统，在完全呼气后进行成像。在我们的100例患者系列中，这种视图对于确定近端左冠状动脉系统动脉的重大病变是必不可少的。
