So as to optimise these procedures, it is adavantageous to have a firm grasp of the anatomy of the normal atrial septal structures, this then providing the basis to understand the morphology of the holes which can exist between the chambers, not all of which are true septal defects.A true septal structure can be removed without exiting from the cavities of the heart. It is the flap valve of the oval fossa, along with the anterior rim of the fossa, which fulfill this criterion. The remainder of the extensive rim of the normal fossa is no more than an infolding between the walls of the right and left atriums and their venous tributaries, and has different dimensions at various points around the ircumference. The so-called muscular atrioventricular \u201cseptum\u201d is a sandwich incorporating a layer of epicardial fibro-adipose tissue. True defects of the atrial septum, therefore, exist because of deficiency, perforation, or absence of the flap valve. Most of these defects will prove suitable for interventional closure, but potential caveats include multiple defects, aneurysm of the flap valve, or adjacency of the fossa to the venous orifices. The other interatrial communications, namely the sinus venosus, coronary sinus, and \u201costium primum\u201d defects are outside the confines of the oval fossa. Recognition of this feature is the key to their diagnosis, and their ifferentiation from true atrial septal defects. Of these defects, only the coronary sinus defect is likely to be suitable for device closure, and then only in the very rare circumstances when it is seen in isolation<\/jats:p>","DOI":"10.1017\/s1047951100008155","type":"journal-article","created":{"date-parts":[[2008,8,31]],"date-time":"2008-08-31T15:54:43Z","timestamp":1220198083000},"page":"464-473","source":"Crossref","is-referenced-by-count":34,"title":["The anatomy of interatrial communications \u2013 what does the interventionist need to know?"],"prefix":"10.1017","volume":"10","author":[{"given":"Jos\u00e9 Diogo","family":"Ferreira Martins","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert H.","family":"Anderson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2008,8,19]]},"reference":[{"key":"S1047951100008155_ref002","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.67.4.316"},{"key":"S1047951100008155_ref011","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.82.3.300"},{"key":"S1047951100008155_ref001","first-page":"1091","article-title":"Transcatheter closure of atrial septal defects","volume":"79","author":"Lock","year":"1989","journal-title":"Experimental studies"},{"key":"S1047951100008155_ref010","doi-asserted-by":"publisher","DOI":"10.1016\/0002-8703(88)90259-1"},{"key":"S1047951100008155_ref003","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.69.1.52"},{"key":"S1047951100008155_ref004","first-page":"573","article-title":"Surgical evaluation of transthoracic tridimensional echocardiography in the anatomic study of atrial septal defect","volume":"92","author":"Bemurat","year":"1999","journal-title":"Arch Mai Coeur Vaiss"},{"key":"S1047951100008155_ref005","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0185(199609)246:1<1::AID-AR1>3.0.CO;2-Y"},{"key":"S1047951100008155_ref006","first-page":"1162","article-title":"Living anatomy of the atrioventricular junctions","volume":"10","author":"Cosio","year":"1999","journal-title":"A guide to electrophysiological mapping"},{"key":"S1047951100008155_ref007","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1098-2353(1999)12:5<362::AID-CA6>3.0.CO;2-F"},{"key":"S1047951100008155_ref008","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.101.6.647"},{"key":"S1047951100008155_ref009","first-page":"1489","article-title":"Incidence and size of patent foramen ovale during the first 10 decades of life: an autopsy study of 965 normal hearts","volume":"59","author":"Hagen","year":"1984","journal-title":"Proc Staff Meet Mayo Clin"},{"key":"S1047951100008155_ref012","doi-asserted-by":"publisher","DOI":"10.1017\/S1047951100008167"},{"key":"S1047951100008155_ref013","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.75.3.593"},{"key":"S1047951100008155_ref015","doi-asserted-by":"publisher","DOI":"10.1017\/S1047951100007903"},{"key":"S1047951100008155_ref016","doi-asserted-by":"publisher","DOI":"10.1017\/S1047951100010362"},{"key":"S1047951100008155_ref017","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.81.2.199"},{"key":"S1047951100008155_ref014","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.78.3.298"}],"container-title":["Cardiology in the Young"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S1047951100008155","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,8]],"date-time":"2019-05-08T16:42:29Z","timestamp":1557333749000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S1047951100008155\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2000,9]]},"references-count":17,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2000,9]]}},"alternative-id":["S1047951100008155"],"URL":"https:\/\/doi.org\/10.1017\/s1047951100008155","relation":{},"ISSN":["1047-9511","1467-1107"],"issn-type":[{"value":"1047-9511","type":"print"},{"value":"1467-1107","type":"electronic"}],"subject":[],"published":{"date-parts":[[2000,9]]}}}
