The complex postoperative complications of TAVR were related to the type of implanted prosthetic valve, and the deep mechanism of this relationship may guide the clinical pre-operative planning. This technical brief developed a numerical method of TAVR to compare the outcome difference between balloon-expandable valve and self-expandable valve and predict the postoperative results. A complete patient-specific aortic model was reconstructed. Two prosthetic valves (balloon-expandable valve and self-expandable valve) were introduced to simulate the implantation procedure, and postprocedural function was studied with fluid\u2013structure interaction method, respectively. Results showed similar stress distribution for two valves, but higher peak stress for balloon-expandable valve model. The balloon-expandable valve was associated with a better circular cross section and smaller paravalvular gaps area. Hemodynamic parameters like cardiac output, mean transvalvular pressure difference, and effective orifice area (EOA) of the balloon-expandable valve model were better than those of the self-expandable valve model. Significant outcome difference was found for two prosthetic valves. Balloon-expandable valve may effectively decrease the risk and degree of postoperative paravalvular leak, while self-expandable valve was conducive to lower stroke risk due to lower aortic stress. The numerical TAVR simulation process may become an assistant tool for prosthesis selection in pre-operative planning and postoperative prediction.<\/jats:p>","DOI":"10.1115\/1.4054332","type":"journal-article","created":{"date-parts":[[2022,4,14]],"date-time":"2022-04-14T09:11:18Z","timestamp":1649927478000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":15,"title":["Comparison of Balloon-Expandable Valve and Self-Expandable Valve in Transcatheter Aortic Valve Replacement: A Patient-Specific Numerical Study"],"prefix":"10.1115","volume":"144","author":[{"given":"Jianming","family":"Li","sequence":"first","affiliation":[{"name":"Department of Aeronautics and Astronautics, Fudan University, Shanghai 200433, China; Institute of Biomechanics, Fudan University, Shanghai 200433, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wentao","family":"Yan","sequence":"additional","affiliation":[{"name":"Department of Aeronautics and Astronautics, Fudan University, Shanghai 200433, China; Institute of Biomechanics, Fudan University, Shanghai 200433, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenshuo","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Zhongshan Hospital Affiliated to Fudan University, Shanghai 200032, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shengzhang","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Aeronautics and Astronautics, Fudan University, Shanghai 200433, China; Academy for Engineering and Technology, Institute of Biomedical Engineering Technology, Fudan University, Shanghai 200433, China; Institute of Biomechanics, Fudan University, Shanghai 200433, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lai","family":"Wei","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Zhongshan Hospital Affiliated to Fudan University, Shanghai 200032, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"33","published-online":{"date-parts":[[2022,5,6]]},"reference":[{"issue":"5","key":"2022050611132841800_bib1","doi-asserted-by":"crossref","first-page":"561","DOI":"10.1016\/j.jacc.2015.05.066","article-title":"Calcification in Aortic Stenosis: The Skeleton Key","volume":"66","year":"2015","journal-title":"J.
