Apart from the pulmonic veins, the interatrial septum (<jats:styled-content style=\"fixed-case\">IAS<\/jats:styled-content>) might play a role in the maintenance of <jats:styled-content style=\"fixed-case\">AF<\/jats:styled-content>. In contrast to left atrial anatomy and adjacent veins, the <jats:styled-content style=\"fixed-case\">IAS<\/jats:styled-content> cannot be visualized in detail with computed tomography. Thus, preprocedural transesophageal echocardiography (<jats:styled-content style=\"fixed-case\">TEE<\/jats:styled-content>) may provide important morphologic information beyond exclusion from atrial thrombi. Methods: The study comprised 108 consecutive patients (mean age 60\u00a0\u00b1\u00a011\u00a0years; 98 men). <jats:styled-content style=\"fixed-case\">AF<\/jats:styled-content> was paroxysmal in 91 (84%) and persistent in 17 (16%) patients. We investigated the morphological characteristics of the <jats:styled-content style=\"fixed-case\">IAS<\/jats:styled-content> by <jats:styled-content style=\"fixed-case\">TEE<\/jats:styled-content> in patients who underwent radiofrequency ablation of <jats:styled-content style=\"fixed-case\">AF<\/jats:styled-content>. Results: The <jats:styled-content style=\"fixed-case\">IAS<\/jats:styled-content> was structurally abnormal in 46 (43%) patients, showing the following echocardiograhic findings: atrial septal hypermobility or aneurysm (n\u00a0=\u00a027) associated with a patent foramen ovale (<jats:styled-content style=\"fixed-case\">PFO<\/jats:styled-content>) (n\u00a0=\u00a011) or with a small atrial septal defect (<jats:styled-content style=\"fixed-case\">ASD<\/jats:styled-content>) (n\u00a0=\u00a02), a septal flap associated with a <jats:styled-content style=\"fixed-case\">PFO<\/jats:styled-content> or an <jats:styled-content style=\"fixed-case\">ASD<\/jats:styled-content> (n\u00a0=\u00a08), and an abnormally thickened <jats:styled-content style=\"fixed-case\">IAS<\/jats:styled-content> (n\u00a0=\u00a012). A thrombus in the left atrial appendage was discovered in only 2 (2%) patients. Conclusions: A structurally abnormal <jats:styled-content style=\"fixed-case\">IAS<\/jats:styled-content> was diagnosed in nearly half of the patients undergoing ablation therapy for <jats:styled-content style=\"fixed-case\">AF<\/jats:styled-content>. The information obtained by <jats:styled-content style=\"fixed-case\">TEE<\/jats:styled-content> is mandatory to exclude left atrial thrombi prior the ablation procedure. Moreover, detailed knowledge of morphologic characteristics of the <jats:styled-content style=\"fixed-case\">IAS<\/jats:styled-content> facilitates an optimized and safe performance of the transseptal puncture using long sheaths with large diameters.<\/jats:p>","DOI":"10.1111\/echo.12067","type":"journal-article","created":{"date-parts":[[2012,12,12]],"date-time":"2012-12-12T02:09:35Z","timestamp":1355278175000},"page":"402-406","source":"Crossref","is-referenced-by-count":14,"title":["High Incidence of Echocardiographic Abnormalities of the Interatrial Septum in Patients Undergoing Ablation for Atrial Fibrillation"],"prefix":"10.1111","volume":"30","author":[{"given":"Christiana","family":"Schernthaner","sequence":"first","affiliation":[{"name":"Department of Cardiology Paracelsus Private Medical University Salzburger Landeskliniken Salzburg Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Franz","family":"Danmayr","sequence":"additional","affiliation":[{"name":"Department of Cardiology Paracelsus Private Medical University Salzburger Landeskliniken Salzburg Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Apollonia","family":"Daburger","sequence":"additional","affiliation":[{"name":"Department of Cardiology Paracelsus Private Medical University Salzburger Landeskliniken Salzburg Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00f6rg","family":"Eichinger","sequence":"additional","affiliation":[{"name":"Department of Cardiology Paracelsus Private Medical University Salzburger Landeskliniken Salzburg Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthias","family":"Hammerer","sequence":"additional","affiliation":[{"name":"Department of Cardiology Paracelsus Private Medical University Salzburger Landeskliniken Salzburg Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bernhard","family":"Strohmer","sequence":"additional","affiliation":[{"name":"Department of Cardiology Paracelsus Private Medical University Salzburger Landeskliniken Salzburg Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2012,12,10]]},"reference":[{"key":"e_1_2_5_2_1","first-page":"25","article-title":"Lipomatous hypertrophy of the interatrial septum","volume":"68","author":"Kluge WF","year":"1969","journal-title":"Northwest Med"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8175.2005.04088.x"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199809033391003"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.0000109495.02213.52"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(94)90133-3"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1023\/A:1009818210563"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2011.12.016"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1186\/1476-7120-3-5"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-8703(71)90156-6"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(03)00918-5"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1540-8183.2003.08000.x"},{"key":"e_1_2_5_13_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8175.2005.00129.x"},{"key":"e_1_2_5_14_1","doi-asserted-by":"publisher","DOI":"10.1093\/europace\/eur366"}],"container-title":["Echocardiography"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fecho.12067","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/echo.12067","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,16]],"date-time":"2023-10-16T07:21:42Z","timestamp":1697440902000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/echo.12067"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,12,10]]},"references-count":13,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2013,4]]}},"alternative-id":["10.1111\/echo.12067"],"URL":"https:\/\/doi.org\/10.1111\/echo.12067","archive":["Portico"],"relation":{},"ISSN":["0742-2822","1540-8175"],"issn-type":[{"value":"0742-2822","type":"print"},{"value":"1540-8175","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012,12,10]]}}}
