OBJECTIVE
To evaluate the prevalence and characteristics of myocardial bridging in patients who underwent single- or dual-source multidetector cardiac computed tomographic angiography (MDCTA).
METHODS
Retrospective review of the imaging characteristics of 57 myocardial bridges in 53 patients who underwent cardiac MDCTA examinations was performed.
RESULTS
The prevalence of myocardial bridges was 10.4%, most of which were located in the mid-left anterior descending coronary artery. The average myocardial bridge length was 23.4 mm, and the average tunneled artery depth was 2.6 mm.
CONCLUSIONS
Myocardial bridges are commonly found in patients who undergo cardiac multidetector computed tomographic angiograms on both single- and dual-source computed tomographic scanners and are most frequently located in the mid-left anterior descending coronary artery. Increasing utilization of cardiac MDCTA for noninvasive evaluation of coronary artery disease permits recognition, characterization, and functional assessment of this entity in a single examination.
目的
评估接受单源或双源多排螺旋心脏计算机断层扫描血管造影（MDCTA）的患者中心肌桥的患病率及特征。
方法
对53例接受心脏MDCTA检查的患者中57个心肌桥的影像特征进行回顾性分析。
结果
心肌桥的患病率为10.4%，大部分位于左前降支冠状动脉中段。心肌桥平均长度为23.4毫米，动脉走行于心肌下的平均深度为2.6毫米。
结论
在接受单源和双源计算机断层扫描仪心脏多排螺旋计算机断层扫描血管造影的患者中，心肌桥很常见，且最常位于左前降支冠状动脉中段。心脏MDCTA在冠状动脉疾病无创评估中的应用增加，使得在一次检查中即可识别、描述和评估该病变。
