Results
29 patients (30%, 24 male, mean age 58±12) presented single (86%) or double (14%) myocardial bridging with variable length (<1 cm in the 48%, 1-2 cm in the 40%, >2 cm in the 12%). Superficial (76%) or intramyocardial (24%) bridges were detected. Myocardial bridging was frequently localized in the mid-distal segment of the left anterior descending artery (93%).
Coronary segments proximal to the bridge presented no atherosclerotic disease (n=7), positive remodelling (n=4), wall irregularities (n=4), <50% stenoses (n=9), >50% stenoses (n=6), or occlusion (n=3). 4 non calcified, 13 mixed, and 9 calcified plaques were detected. Assessable distal segments (61%) presented the following atherosclerosis extent: absence of disease (n=11), no significant lesions (n=8), and >50% stenosis (n=1) (Fig. 6-16).
