Congenital atresia of the left main coronary artery, a condition in which the left main trunk is developed but has been occluded since birth, is a rare coronary anomaly. Herein, we describe this anomaly's association with a subannular location of an obliterated left main ostium in a patient with a bicuspid aortic valve and severe aortic stenosis. The patient underwent successful surgery. We discuss the embryologic implications of congenital atresia of the left main coronary artery, in view of the exceptional anatomic features of this condition. To our knowledge, this is the 1st report of a left coronary artery that was found to arise from the left ventricle.
左冠状动脉先天性闭锁是一种罕见的冠状动脉异常，其左主干已发育，但自出生以来就已闭塞。在此，我们描述了一名患有二叶式主动脉瓣和严重主动脉狭窄的患者中，这种异常与闭锁的左主开口瓣下位置的关联。该患者手术成功。鉴于这种情况特殊的解剖特征，我们讨论了左冠状动脉先天性闭锁的胚胎学意义。据我们所知，这是首次报告左冠状动脉起源于左心室。
