心肌桥是一种常见的冠状动脉先天解剖发育异常，传统观点认为是一种良性病变，不会引起临床症状和体征。但近来研究表明，心肌桥能够导致心律失常、心肌梗死及猝死的恶性心血管事件的发生，因此对于心肌桥的检出具有重要的临床意义。选择性冠状动脉造影、多层螺旋CT血管造影、核素显像、血管内超声(IVUS)和彩色多普勒技术(CDUS)、传统X射线冠状动脉造影(CAG)、多排螺旋CT(MDCT)以及磁共振(MRI)等影像学技术对心肌桥检出、诊断的价值以及限度进行综合分析，认为多层螺旋CT血管造影是诊断心肌桥的首选手段。

Myocardial bridge is a common coronary artery anatomy of the congenital dysplasia, conventional wisdom is that it is a kind of benign lesions, without causing clinical signs and symptoms, but recent studies have shown that it can lead to cardiac arrhythmia, myocardial infarction, sudden death of the occurrence of adverse cardiovascular events, so for the detection of myocardial bridge has important clinical significance. Selective coronary angiography were reviewed, multislice CT angiography and radionuclide imaging and intravascular ultrasound imaging techniques for the detection of myocardial bridge, clinical value and limits, comprehensive analysis, think that multislice CT angiography is the first choice for diagnosis of myocardial bridge.
