Correlations of anatomic and functional MB properties with maximum plaque burden at the proximal reference and the myocardial bridge segment. At the proximal reference (A), arterial compression showed a weak but significant positive correlation with maximum plaque burden. In contrast, no correlation was observed in anatomic properties of an MB, including MB length, thickness of halo, and the location of the MB based on its distance from the LAD orifice. At the MB segment (B), maximum plaque burden showed no association with any MB properties. LAD indicates left anterior descending artery; Max PBMB, maximum plaque burden with the myocardial bridge segment; Max PBProx, maximum plaque burden within a 20‐mm segment immediately proximal to the myocardial bridge entrance; MB, myocardial bridge.
