This study aims to develop a patient-specific CFD model of MB. There were two parts to this study. The first part consisted of developing an in silico model of the left anterior descending (LAD) coronary artery of a patient with MB. In this regard, a moving-boundary CFD algorithm was developed to simulate the patient-specific muscle compression caused by MB. A second simulation was also performed with the bridge artificially removed to determine the hemodynamics in the same vessel in the absence of MB. The second part of the study consisted of hemodynamic analysis of three patients with mild and moderate and severe MB in their LAD by means of the developed in silico model in the first part. The average shear stress in the proximal and bridge segments for model with MB were significantly different from those for model without MB (proximal segment: 0.32\u2009\u00b1\u20090.14\u2009Pa (with MB) versus 0.97\u2009\u00b1\u20090.39\u2009Pa (without MB), P\u2009&lt;\u20090.0001 \u2014 bridge segment: 2.60\u2009\u00b1\u20090.94\u2009Pa (with MB) versus 1.50\u2009\u00b1\u20090.64\u2009Pa (without MB), P\u2009&lt;\u20090.0001). When all three patients were evaluated, increasing the degree of vessel compression shear stress in the proximal segment decreased, whereas the shear stress in the bridge segment increased. The presence of MB resulted in hemodynamic abnormalities in the proximal segment, whereas segments within the bridge exhibited hemodynamic patterns which tend to discourage atheroma development.<\/jats:p>","DOI":"10.1115\/1.4040127","type":"journal-article","created":{"date-parts":[[2018,5,25]],"date-time":"2018-05-25T18:31:36Z","timestamp":1527273096000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":13,"title":["Development of a Computational Fluid Dynamics Model for Myocardial Bridging"],"prefix":"10.1115","volume":"140","author":[{"given":"Ashkan","family":"Javadzadegan","sequence":"first","affiliation":[{"name":"Faculty of Medicine and Health Sciences, Macquarie University, Level 1, 75 Talavera Road, Sydney 2109, NSW, Australia;"},{"name":"ANZAC Research Institute, The University of Sydney, Sydney 2139, NSW, Australia e-mail:"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abouzar","family":"Moshfegh","sequence":"additional","affiliation":[{"name":"Faculty of Medicine and Health Sciences, Macquarie University, Sydney 2109, NSW, Australia;"},{"name":"ANZAC Research Institute, The University of Sydney, Sydney 2139, NSW, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Fulker","sequence":"additional","affiliation":[{"name":"School of Mechanical and Manufacturing Engineering, University of New South Wales, Sydney 2052, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tracie","family":"Barber","sequence":"additional","affiliation":[{"name":"School of Mechanical and Manufacturing Engineering, University of New South Wales, Sydney 2052, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi","family":"Qian","sequence":"additional","affiliation":[{"name":"Faculty of Medicine and Health Sciences, Macquarie University, Sydney 2109, NSW, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leonard","family":"Kritharides","sequence":"additional","affiliation":[{"name":"ANZAC Research Institute, The University of Sydney, Sydney 2139, NSW, Australia;"},{"name":"Department of Cardiology, Concord Hospital, The University of Sydney, Sydney 2139, NSW, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andy S.
