Myocardial bridging is a congenital coronary pathology described as a segment of coronary artery which courses through the myocardial wall under the muscle bridge. Although the prognosis of myocardial bridging is benign, sports medicine recognises myocardial bridging as a leading cause of sudden death among young basketball, football and soccer players. The authors report a case of a 42-year-old man who collapsed while playing football. He died notwithstanding prompt medical assistance and cardiopulmonary resuscitation. At autopsy, gross examination of the heart revealed the intramural course of the left anterior descending coronary artery to be 2 cm from its coronary ostial origin. Histological examination of ventricular septal and left myocardium showed early signs of ischaemic injury without disease of small coronary vessels and hypertrophic cardiomyopathy. The cause of the death was due to malignant ventricular arrhythmia during intense physical activity.
心肌桥是一种先天性冠状动脉疾病，表现为一段冠状动脉在肌肉桥下方穿过心肌壁。尽管心肌桥的预后良好，但运动医学认为心肌桥是导致年轻篮球、足球和足球运动员猝死的主要原因之一。作者报告了一例 42 岁男性在踢足球时晕倒的病例。尽管得到了及时的医疗救助和心肺复苏，但他还是死亡了。尸检时，心脏的大体检查显示左前降支冠状动脉在距离其冠状动脉开口 2 厘米处穿过心肌壁。心室间隔和左心肌的组织学检查显示早期缺血损伤的迹象，而无小冠状动脉疾病和肥厚型心肌病。死亡的原因是剧烈体力活动时发生恶性室性心律失常。
