研究背景:心肌桥-壁冠状动脉(MB-MCA)是一种先天性冠状动脉解剖变异,一直被认为是种良性病变。一般情况下,不引起临床症状,但可能出现心肌缺血、心律失常、心肌梗死及猝死等临床表现。明确MB-MCA的形态学特征及其与冠状动脉粥样硬化之间的关系,为相关疾病的诊断及治疗提供解剖依据。 目的:(1)应用64排多层螺旋CTA观察并测量MB-MCA发生率及其形态学特征;(2)探讨左前降支心肌桥(LAD-MB)与冠状动脉粥样硬化的关系。 实验方法:(1)回顾性分析本院2013.05-2014.05期间行冠状动脉64排螺旋CTA检查数据912例(男性542例,女性370例,年龄范围23~86岁,平均年龄...Background: Myocardial bridge-mural coronary artery (MB-MCA) is a congenital coronary anatomical abnormality,which was generally considered benign. In most cases, MB subjects are clinically silent, but sometimes have clinical signs, such as myocardial ischemia, arrhythmia, myocardial infarction and sudden death. It is helpful to make clear the characteristics of MB-MCA and the correlation with cor...学位:医学硕士院系专业:医学院_影像医学与核医学学号:2452012115322
