An anomalous origin of the left coronary artery (LCA) is a relatively uncommon congenital heart defect that can lead to myocardial ischemia and sudden cardiac death. An LCA arising from the pulmonary artery and an LCA arising from the opposite sinus of Valsalva are the common types of anomalous origins of the LCA. Echocardiographic assessment of the coronary arteries is an important component of the routine cardiovascular evaluation, but echocardiographic "pseudo images" of LCA origination can be present in some patients. Detection of an anomalous origin of the LCA remains a challenge to sonographers.
左冠状动脉（LCA）异常起源是一种相对罕见的先天性心脏缺陷，可导致心肌缺血和心源性猝死。起源于肺动脉的LCA和起源于对侧瓦尔萨尔瓦窦的LCA是LCA异常起源的常见类型。冠状动脉的超声心动图评估是常规心血管评估的重要组成部分，但部分患者可能会出现LCA起源的超声心动图“伪像”。LCA异常起源的检测对超声检查人员来说仍是一项挑战。
