We present a novel technique employing biplane cineangiography with simultaneous left coronary and pulmonary angiography to define the anomalous course of the left main coronary artery when it originates from the right sinus of Valsalva. These biplane cinearterlograms clearly define the relationship of the left main coronary artery to the great vessels, allowing confident delineation of the interarterial variant from the other, benign variants. We illustrate the advantages of this technique with two cases in which the course of the anomalous left main coronary artery was incorrectly diagnosed using standard coronary arteriography and magnetic resonance imaging.
我们提出了一种新技术，该技术采用双平面电影血管造影术同时进行左冠状动脉和肺动脉造影，以确定起源于瓦尔萨尔瓦右窦的左冠状动脉主干的异常走行。这些双平面电影血管造影片清晰地界定了左冠状动脉主干与大血管的关系，从而能够可靠地将动脉间变异与其他良性变异区分开来。我们通过两个病例说明了该技术的优势，在这两个病例中，使用标准冠状动脉造影和磁共振成像对异常左冠状动脉主干的走行进行了错误诊断。
