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.
