摘要 冠状动脉分支通常走行于心外膜下脂肪组织中,但有时部分节段被心肌纤维所覆盖,在心肌内行走一段距离后又浅露于心肌表面,覆盖在该段冠状动脉上的心肌束称为心肌桥(MB),而位于心肌桥下的冠状动脉称为壁冠状动脉(MCA或tunnelled artery),这一复合体为“MB—MCA”,即心肌桥-壁冠状动脉。MB—MCA一般被认为是良性先天性发育异常。临床不表现症状。近年有关MB—MCA引起心肌退变、与动脉硬化相关、心律不齐、导致急性心肌缺血、甚至与猝死相关联等均有报告,这引起人们对MB—MCA临床意义的再关注。因此需要一种敏感、可靠、客观的方法来确定活体心肌桥的存在,以便对MB—MCA做出早期诊断,并对其是否引起心肌缺血机制及其与动脉硬化关系等进行深入研究。明确MB—MCA临床意义。随着医学影像技术的发展,各种影像技术在这些方面中的应用越来越多。本文就此作一综述。
