CONCLUSIONS Myocardial bridging of coronary arteries is common on CTA, but only approximately one-third of these show systolic compression. Myocardial bridging is not associated with reduced myocardial perfusion during vasodilator stress. Atherosclerosis is Located predominantly proximal to myocardial bridging but atherosclerotic burden and presence of vulnerable plaques were comparable.
