OBJECTIVES
The aim of this study was to retrospectively evaluate the morphologic and functional features of myocardial bridging (MB) and to investigate the impact of morphologic features on presence of atherosclerosis with multi-detector computed tomography (MDCT) coronary angiography.

STUDY DESIGN
The study population consisted of 191 consecutive patients. Besides coronary lesions, morphologic features of the MB (depth, length and the distance of the tunneled artery from the left coronary ostium) were analyzed.

RESULTS
MDCT detected MB on left anterior descending artery in 41 patients (21.5%). The prevalence of atherosclerotic plaques proximal to the MB of LAD was 49% (20/41). There was a statistically significant correlation between percentage of systolic compression and depth of the tunneled segment (r=0.538, p<0.01). There was no relation between distance of the tunneled segment from the ostium and degree of systolic compression. No significant correlation was found between percentage of systolic compression and length of the tunneled segment (r=0.058, p=0.721). Morphologic features of MB were not related to the presence of CAD in proximal segments.

CONCLUSION
MDCT coronary angiography depicts the morphologic and functional features of the MB in detail. The depth of MB segment was correlated with systolic compression of MB. There was no relationship between distance of the tunneled segment from the ostium and systolic compression.
