No reports have analyzed the use of the foramen ovale position to effectively guide transseptal punctures on chest X-rays or computed tomography scout views, which are more cost-effective approaches to safely and effectively guide the procedure. We aimed to find the foramen ovale position on chest computed tomography scout views to effectively guide percutaneous transseptal punctures. Materials and Methods: The study population included 31 patients treated with extracorporeal membrane oxygenation (ECMO) for cardiogenic shock, 32 patients diagnosed with atrial fibrillation (AF) who underwent MDCT, and 197 patients who underwent MDCT for non-cardiac conditions. Vertebral body units, defined as the distance between two adjacent vertebral bodies (the sixth and seventh thoracic spines) inclusive of the intervertebral disk space, were used to express the distance from the carina to the foramen ovale on computed tomography scout views. Results: The mean vertebral body units, distance from the carina to the foramen ovale (carina\u2013foramen ovale), and distance from the carina to the foramen ovale on chest computed tomography scout views (carina\u2013foramen ovale vertebral body units\u22121) were 2.3 \u00b1 0.2 cm, 6.9 \u00b1 0.9 cm, and 3.0 \u00b1 0.3, respectively. Multivariate analysis showed significant correlations between the carina\u2013foramen ovale vertebral body units\u22121 and sex (\u03b2 = 0.080; p = 0.028), body mass index (\u03b2 = \u22120.020; p &lt; 0.001), age (\u03b2 = 0; p = 0.013), and the application of extracorporeal membrane oxygenation or the presence of atrial fibrillation (\u03b2 = 0.130; p = 0.004). Conclusions: Although a three-dimensional approach was not employed, the foramen ovale position may serve as a radiologic guide in various clinical settings where transseptal punctures are required. This technique may be an effective aid in transseptal puncture procedures.<\/jats:p>","DOI":"10.3390\/medicina61050896","type":"journal-article","created":{"date-parts":[[2025,5,15]],"date-time":"2025-05-15T06:10:44Z","timestamp":1747289444000},"page":"896","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Optimal Localization of the Foramen Ovale for Transseptal Puncture Using the Vertebral Body Units"],"prefix":"10.3390","volume":"61","author":[{"given":"Dong Hoon","family":"Kang","sequence":"first","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Gyeongsang National University College of Medicine and Gyeongsang National University Changwon Hospital, Changwon 51472, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2832-8900","authenticated-orcid":false,"given":"Sung Eun","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Radiology, Gyeongsang National University College of Medicine, Changwon 52828, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jong Woo","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Gyeongsang National University College of Medicine and Gyeongsang National University Changwon Hospital, Changwon 51472, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seong Ho","family":"Moon","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Gyeongsang National University College of Medicine and Gyeongsang National University Changwon Hospital, Changwon 51472, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ho Jeong","family":"Cha","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Gyeongsang National University College of Medicine and Gyeongsang National University Changwon Hospital, Changwon 51472, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jong Hwa","family":"Ahn","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Gyeongsang National University College of Medicine and Gyeongsang National University Changwon Hospital, Changwon 51472, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1909-664X","authenticated-orcid":false,"given":"Joung Hun","family":"Byun","sequence":"additional","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Gyeongsang National University College of Medicine and Gyeongsang National University Changwon Hospital, Changwon 51472, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"653","DOI":"10.1016\/0002-9149(59)90347-9","article-title":"Transseptal left atrial puncture: New technique for the measurement of left atrial pressure in man","volume":"3","author":"Ross","year":"1959","journal-title":"Am.
