Recent reports indicate that PWI can help the assessment of atherosclerotic plaque composition and mechanical properties. However, the effect of the atherosclerotic plaque's geometry and mechanics on the arterial wall distension and local PWV remains unclear. In this study, we investigated the accuracy of a finite element (FE) fluid\u2013structure interaction (FSI) approach to predict the velocity of a pulse wave propagating through a stenotic artery with an asymmetrical plaque, as quantified with PWI method. Experiments were designed to compare FE-FSI modeling of the pulse wave propagation through a stenotic artery against PWI obtained with manufactured phantom arteries made of polyvinyl alcohol (PVA) material. FSI-generated spatiotemporal maps were used to estimate PWV at the plaque region and compared it to the experimental results. Velocity of the pulse wave propagation and magnitude of the wall distension were correctly predicted with the FE analysis. In addition, findings indicate that a plaque with a high degree of stenosis (&amp;gt;70%) attenuates the propagation of the pulse pressure wave. Results of this study support the validity of the FE-FSI methods to investigate the effect of arterial wall structural and mechanical properties on the pulse wave propagation. This modeling method can help to guide the optimization of PWI to characterize plaque properties and substantiate clinical findings.<\/jats:p>","DOI":"10.1115\/1.4048708","type":"journal-article","created":{"date-parts":[[2020,10,8]],"date-time":"2020-10-08T10:25:45Z","timestamp":1602152745000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":7,"title":["Modeling Pulse Wave Propagation Through a Stenotic Artery With Fluid Structure Interaction: A Validation Study Using Ultrasound Pulse Wave Imaging"],"prefix":"10.1115","volume":"143","author":[{"given":"Vittorio","family":"Gatti","sequence":"first","affiliation":[{"name":"Department of Biomedical Engineering, Columbia University, New York, NY 10027"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pierre","family":"Nauleau","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Columbia University, New York, NY 10027"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Grigorios M.","family":"Karageorgos","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Columbia University, New York, NY 10027"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jay J.","family":"Shim","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Columbia University, New York, NY 10027"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gerard A.","family":"Ateshian","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Columbia University, New York, NY 10027"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elisa E.","family":"Konofagou","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Columbia University, New York, NY 10027; Department of Radiology, Columbia University, 351 Engineering Terrace, Mail Code 8904, New York, NY 10027"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"33","published-online":{"date-parts":[[2020,12,10]]},"reference":[{"issue":"3","key":"2020121004064552500_bib1","doi-asserted-by":"crossref","first-page":"137","DOI":"10.1177\/016173460702900301","article-title":"A Novel, Non-Invasive Technique for Pulse-Wave Imaging and Characterization of Clinically Significant Vascular Mechanical Properties In Vivo","volume":"29","year":"2007","journal-title":"Ultrason.
