Coronary artery anomalies are associated often with myocardial ischemia or sudden cardiac death. A 19-year-old woman who participated in an exertive game lost consciousness upon one such exertion. She was taken to a hospital where she died on the same day. An autopsy revealed that she had bifurcated coronary arteries, which arose from one coronary ostium in the left sinus of Valsalva. The right coronary artery arose from the left sinus and traveled between the aorta and the pulmonary trunk. The heart as well as the cardiac conduction system depended exclusively on the single coronary artery ostium for oxygenated blood supply, and the unbalanced blood distribution on her exertion probably led to sudden cardiac death. The case highlights the medicolegal importance of unexpected sudden cardiac death related to an anomalous origin of the coronary arteries.
冠状动脉异常常与心肌缺血或心源性猝死有关。一名 19 岁的女性在进行剧烈运动时突然失去意识。她被送往医院，当天死亡。尸检显示她的冠状动脉呈双叉状，发自左窦的单一冠状动脉开口。右冠状动脉发自左窦，穿行于主动脉和肺动脉干之间。心脏和心脏传导系统完全依赖单一冠状动脉开口供氧，她在剧烈运动时的血液分布不平衡可能导致心源性猝死。本病例强调了与冠状动脉异常起源相关的意外心源性猝死的法医学重要性。
