The stent-induced flow disturbances, and especially the altered wall shear stress (WSS) profile at the strut level, play an important role in the pathophysiological mechanisms leading to stent thrombosis (ST) and in-stent restenosis (ISR). In this context, the analysis of the WSS topological skeleton is gaining more and more interest by extending the current understanding of the association between local hemodynamics and vascular diseases. This study aims to analyze the impact that a deployed coronary stent has on the WSS topological skeleton. Computational fluid dynamics (CFD) simulations were performed in three stented human coronary artery geometries reconstructed from clinical images. The selected cases presented stents with different designs (i.e., two contemporary drug-eluting stents and one bioresorbable scaffold) and included regions with stent malapposition or overlapping. A recently proposed Eulerian-based approach was applied to analyze the WSS topological skeleton features. The results highlighted that the presence of single or multiple stents within a coronary artery markedly impacts the WSS topological skeleton. In particular, repetitive patterns of WSS divergence were observed at the luminal surface, highlighting a WSS contraction action exerted proximal to the stent struts and a WSS expansion action distal to the stent struts. This WSS action pattern was independent from the stent design. In conclusion, these findings could contribute to a deeper understanding of the hemodynamics-driven processes underlying ST and ISR.<\/jats:p>","DOI":"10.1115\/1.4053503","type":"journal-article","created":{"date-parts":[[2022,1,11]],"date-time":"2022-01-11T14:11:55Z","timestamp":1641910315000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":18,"title":["Coronary Artery Stenting Affects Wall Shear Stress Topological Skeleton"],"prefix":"10.1115","volume":"144","author":[{"given":"Claudio","family":"Chiastra","sequence":"first","affiliation":[{"name":"PoliToBIOMed Lab, Department of Mechanical and Aerospace Engineering, Politecnico di Torino, Turin 10129, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valentina","family":"Mazzi","sequence":"additional","affiliation":[{"name":"PoliToBIOMed Lab, Department of Mechanical and Aerospace Engineering, Politecnico di Torino, Turin 10129, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maurizio","family":"Lodi Rizzini","sequence":"additional","affiliation":[{"name":"PoliToBIOMed Lab, Department of Mechanical and Aerospace Engineering, Politecnico di Torino, Turin 10129, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karol","family":"Cal\u00f2","sequence":"additional","affiliation":[{"name":"PoliToBIOMed Lab, Department of Mechanical and Aerospace Engineering, Politecnico di Torino, Turin 10129, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Corti","sequence":"additional","affiliation":[{"name":"Laboratory of Biological Structure Mechanics (LaBS), Department of Chemistry, Materials and Chemical Engineering \u201cGiulio Natta,\u201d Politecnico di Milano, Milan 20133, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alessandro","family":"Acquasanta","sequence":"additional","affiliation":[{"name":"PoliToBIOMed Lab, Department of Mechanical and Aerospace Engineering, Politecnico di Torino, Turin 10129, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giuseppe","family":"De Nisco","sequence":"additional","affiliation":[{"name":"PoliToBIOMed Lab, Department of Mechanical and Aerospace Engineering, Politecnico di Torino, Turin 10129, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Davide","family":"Belliggiano","sequence":"additional","affiliation":[{"name":"Cardiology Division, San Luigi Gonzaga University Hospital, Orbassano, Turin 10043, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Enrico","family":"Cerrato","sequence":"additional","affiliation":[{"name":"Interventional Cardiology Unit, San Luigi Gonzaga University Hospital, Orbassano, Turin 10043, Italy; Interventional Cardiology Unit, Rivoli Infermi Hospital, Rivoli, Turin 10098, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Diego","family":"Gallo","sequence":"additional","affiliation":[{"name":"PoliToBIOMed Lab, Department of Mechanical and Aerospace Engineering, Politecnico di Torino, Turin 10129, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Umberto","family":"Morbiducci","sequence":"additional","affiliation":[{"name":"PoliToBIOMed Lab, Department of Mechanical and Aerospace Engineering, Politecnico di Torino, Turin 10129, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"33","published-online":{"date-parts":[[2022,2,15]]},"reference":[{"issue":"11","key":"2022021511263962100_bib1","doi-asserted-by":"crossref","first-page":"1969","DOI":"10.1253\/circj.CJ-21-0581","article-title":"Stent Edge Restenosis\u2014An Inevitable Drawback of Stenting?","volume":"85","year":"2021","journal-title":"Circ.
