In the native aorta, efficient storage and release of mechanical energy are essential for maintaining ventriculo\u2013aortic coupling. The energy dissipation ratio (EDR) quantifies the proportion of mechanical energy lost during a loading\u2013unloading cycle and may provide insight into the biomechanical performance of aortic substitutes. Bovine pericardial patches (BPPs) are widely used in cardiovascular surgery for arterial reconstruction, patch angioplasty, and tubular replacement. Today, EDR has not been systematically investigated in BPPs. Methods: Forty glutaraldehyde-treated BPPs from four commercial manufacturers (n = 10 per supplier) were subjected to low-cycle fatigue testing using a uniaxial tensile system under controlled physiological conditions (37 \u00b0C). Standardized bone-shaped specimens were tested at progressive strain percentage levels. Thickness, EDR, and the percentage of specimens failing to reach progressively higher strain levels were evaluated from stress\u2013strain hysteresis loops. Results: BPPs thickness ranged from 0.253 to 0.608 mm, with no significant differences among most groups. For the 10% strain, all BPPs reached the target deformation and demonstrated comparable EDR values. In detail, the mean EDR was 21.40 \u00b1 7.02% for Edwards Lifesciences, 24.95 \u00b1 6.80% for Supple Peri-Guard (Baxter), 24.99 \u00b1 6.04% for Xenosure (LeMaitre), and 23.37 \u00b1 6.12% for Invengenx\u2013Tisgenx, with no statistically significant intergroup differences (p &gt; 0.05). For the 20% strain, only 18.75% of specimens remained structurally intact, and variability increased. At 30% strain, structural failure occurred in nearly all samples. No significant orientation-dependent differences were observed. Conclusions: Commercially available BPPs exhibit similar biomechanical behavior under moderate deformation. However, tolerance to higher strain is limited. EDR analysis provides a clinically relevant parameter to assess elastic performance and may contribute to optimizing aortic substitute selection.<\/jats:p>","DOI":"10.3390\/jfb17080362","type":"journal-article","created":{"date-parts":[[2026,7,28]],"date-time":"2026-07-28T13:07:33Z","timestamp":1785244053000},"page":"362","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Analysis of Energy Dissipation Ratio in Commercial Bovine Pericardial Patches Treated with Glutaraldehyde Solution"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0921-7030","authenticated-orcid":false,"given":"Abdulrahman","family":"Alblowi","sequence":"first","affiliation":[{"name":"DCAC, INSERM, Universit\u00e9 de Lorraine, 54000 Nancy, France"},{"name":"Department of Vascular and Endovascular Surgery, Nancy Regional University Hospital, University of Lorraine, 54500 Vandoeuvre-les-Nancy, France"},{"name":"ICMUB CNRS UMR 6302, Universit\u00e9 Bourgogne Europe, 21000 Dijon, France"},{"name":"Division of Vascular and Endovascular Surgery, Department of General Surgery, King Fahad Hospital of the University, College of Medicine, Imam Abdulrahman Bin Faisal University, Dammam 34211, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Siyu","family":"Lin","sequence":"additional","affiliation":[{"name":"ICMUB CNRS UMR 6302, Universit\u00e9 Bourgogne Europe, 21000 Dijon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olivier","family":"Bouchot","sequence":"additional","affiliation":[{"name":"D\u00e9partement de Chirurgie Cardiovasculaire et Thoracique, CHU Dijon Bourgogne, ICMUB UMR 6302, CNRS, Universit\u00e9 Bourgogne Europe, 21000 Dijon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0811-565X","authenticated-orcid":false,"given":"Jeremy","family":"Lagrange","sequence":"additional","affiliation":[{"name":"DCAC, INSERM, Universit\u00e9 de Lorraine, 54000 Nancy, France"},{"name":"IHU Infiny, CHRU Nancy, 54500 Vandoeuvre-les-Nancy, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3107-2771","authenticated-orcid":false,"given":"Nicla","family":"Settembre","sequence":"additional","affiliation":[{"name":"DCAC, INSERM, Universit\u00e9 de Lorraine, 54000 Nancy, France"},{"name":"Department of Vascular and Endovascular Surgery, Nancy Regional University Hospital, University of Lorraine, 54500 Vandoeuvre-les-Nancy, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7970-366X","authenticated-orcid":false,"given":"Alain","family":"Lalande","sequence":"additional","affiliation":[{"name":"P\u00f4le Imagerie, CHU Dijon Bourgogne, ICMUB UMR 6302, CNRS, Universit\u00e9 Bourgogne Europe, 21000 Dijon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Serguei","family":"Malikov","sequence":"additional","affiliation":[{"name":"DCAC, INSERM, Universit\u00e9 de Lorraine, 54000 Nancy, France"},{"name":"Department of Vascular and Endovascular Surgery, Nancy Regional University Hospital, University of Lorraine, 54500 Vandoeuvre-les-Nancy, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"117128","DOI":"10.1016\/j.compstruct.2023.117128","article-title":"Impact performances of fiber reinforced polymer composites and cables: A review","volume":"319","author":"Wang","year":"2023","journal-title":"Compos.
