Our aim was to quantify the relationship between the contact force (CF) and the resulting mechanical deformation induced by the catheter tip using an ex vivo model and computational modeling. The catheter tip was inserted perpendicularly into porcine heart samples. CF values ranged from 10 to 80\u00a0g. The computer model was built to simulate the same experimental conditions, and it considered a 3-parameter Mooney-Rivlin model based on hyper-elastic material. We found a strong correlation between the CF and insertion depth (ID) (<jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup>\u2009=\u20090.96, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001), from 0.7\u2009\u00b1\u20090.3\u00a0mm at 10\u00a0g to 6.9\u2009\u00b1\u20090.1\u00a0mm at 80\u00a0g. Since the surface deformation was asymmetrical, two transversal diameters (minor and major) were identified. Both diameters were strongly correlated with CF (<jats:italic>R<\/jats:italic><jats:sup>2<\/jats:sup>\u2009\u2265\u20090.95), from 4.0\u2009\u00b1\u20090.4\u00a0mm at 20\u00a0g to 10.3\u2009\u00b1\u20090.0\u00a0mm at 80\u00a0g (minor), and from 6.4\u2009\u00b1\u20090.7\u00a0mm at 20\u00a0g to 16.7\u2009\u00b1\u20090.1\u00a0mm at 80\u00a0g (major). An optimal fit between computer and experimental results was achieved, with a prediction error of 0.74 and 0.86\u00a0mm for insertion depth and mean surface diameter, respectively.<\/jats:p>\n                <jats:p><jats:bold>Graphical Abstract<\/jats:bold><\/jats:p>","DOI":"10.1007\/s11517-024-03135-7","type":"journal-article","created":{"date-parts":[[2024,6,1]],"date-time":"2024-06-01T05:01:35Z","timestamp":1717218095000},"page":"3283-3292","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Ablation catheter\u2013induced mechanical deformation in myocardium: computer modeling and ex vivo experiments"],"prefix":"10.1007","volume":"62","author":[{"given":"Yukako","family":"Ijima","sequence":"first","affiliation":[]},{"given":"Kriengsak","family":"Masnok","sequence":"additional","affiliation":[]},{"given":"Juan J.","family":"Perez","sequence":"additional","affiliation":[]},{"given":"Ana","family":"Gonz\u00e1lez-Su\u00e1rez","sequence":"additional","affiliation":[]},{"given":"Enrique","family":"Berjano","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9753-898X","authenticated-orcid":false,"given":"Nobuo","family":"Watanabe","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2024,6,1]]},"reference":[{"issue":"1","key":"3135_CR1","doi-asserted-by":"publisher","first-page":"1","DOI":"10.14740\/jocmr4823","volume":"15","author":"R Abbas","year":"2023","unstructured":"Abbas R, Abbas A, Khan TK, Sharjeel S, Amanullah K, Irshad Y (2023) Sudden cardiac death in young individuals: a current review of evaluation, screening and prevention.
