The presence of murmurs is computationally presented for the\n                    <jats:italic>first time<\/jats:italic>\n                    using a qualitative indicator of the acoustic signal. A pulsatile Newtonian blood\u2010flow at the inlet, with Womersley number \u2009=\u200916.5, is considered. For a fusiform (axisymmetric) AAA, a parametric FfSAI study is presented with various height () to diameter () ratios \u2009=\u20090.3, 0.5, 0.7, 1.0, and 1.2, and width () to diameter () ratios \u2009=\u20090.5 and 1.0. Vertical skin\u2010surface velocity () and rupture potential index () are calculated for different configurations. A significant 71% increase in cutoff frequencies of skin\u2010surface acoustic velocity  is found with the variation of  from 0.3 to 1.2\u2014indicating phonoangiography\u2010based diagnosis as well as distinction of aneurysm levels. The proposed CFD\u2010based flow\u2010visualization indicates a vortex impingement on the aneurysm wall as the primary cause of high cutoff frequencies in the acoustic spectrum. A correlation is proposed to calculate rupture\u2010risk through frequency data based on  and  spectrum. The decibel values predicted by neglecting structural flexibility over\u2010predict the bulge level (1)\u2014emphasizing the importance of arterial compliance in a computational study. This work establishes the efficacy of phonoangiography\u2010based diagnosis in assisting medical practitioners with treatment planning and underscores the necessity of using an elastic model for structure.\n                  <\/jats:p>","DOI":"10.1002\/cnm.70158","type":"journal-article","created":{"date-parts":[[2026,3,19]],"date-time":"2026-03-19T16:11:23Z","timestamp":1773936683000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Computational Hemoacoustic Investigation for Phonoangiography\u2010Based Rupture Prediction in Compliant\u00a0Fusiform Abdominal Aortic Aneurysm"],"prefix":"10.1002","volume":"42","author":[{"given":"Sumant R.","family":"Morab","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering Indian Institute of Technology Bombay  Mumbai India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6865-8747","authenticated-orcid":false,"given":"Janani S.","family":"Murallidharan","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering Indian Institute of Technology Bombay  Mumbai India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Atul","family":"Sharma","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering Indian Institute of Technology Bombay  Mumbai India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,3,19]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIR.0000000000000950"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-134-3-200102060-00008"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.67.2.935"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.12.6.798"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM198108203050801"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.25.2.397"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.21.8.1215"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF02510784"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF02477329"},{"issue":"2","key":"e_1_2_10_11_1","first-page":"213","article-title":"Use of a Pressure\u2010Weighted Interpolation Method for the Solution of the Incompressible Navier\u2010Stokes Equations on a Nonstaggered Grid System","volume":"14","author":"Miller T.
