Myocardial bridging (MB) is defined as an intramural segment of a coronary artery that normally courses epicardially. MB is usually a benign condition; however, some cases resulting in myocardial ischaemia, infarction and sudden death have been reported. We describe a case of myocardial infarction related to MB in a young healthy woman with no risk factors for coronary artery disease. The bridge was demonstrated in detail by coronary CT angiography using multiplanar reconstruction and three-dimensional volume-rendered techniques.
心肌桥（MB）定义为冠状动脉的一段壁内节段，该节段通常走行于心脏表面。心肌桥通常为良性病变；然而，已有一些导致心肌缺血、梗死及猝死的病例报道。我们描述了一例年轻健康女性发生的与心肌桥相关的心肌梗死，该女性无冠状动脉疾病危险因素。通过冠状动脉CT血管造影，采用多平面重建和三维容积再现技术详细显示了心肌桥。
