Myocardial bridging, a common anatomical variant rather than a congenital anomaly.

The recent introduction of coronary computed tomographic angiography into clinical use as a noninvasive tool for coronary artery evaluation has evoked a new interest in myocardial bridging. Recent studies using multidetector computed tomography for the evaluation of coronary anatomy have shown myocardial bridging to be more prevalent than previously reported in angiographic series. The purpose of this article was to provide an overview of the current knowledge on the prevalence and features of myocardial bridging as shown by multidetector computed tomography and to discuss the potential clinical implications of this entity.
