It was earlier believed that a 'common wall' separated the right pulmonary veins from the superior caval vein. In the sinus venosus defects, this wall was absent. Current evidence shows that the superior rim of the oval fossa, rather than forming a second septum or representing a common wall, is an infolding between the walls of the caval veins and the right pulmonary veins. The sinus venosus defect is caused by the anomalous connection of one or more pulmonary veins to a systemic vein. However, the pulmonary vein(s) retain their left atrial connections, leading to a veno-venous bridge that allows interatrial shunting outside the oval fossa. True atrial septal defects are located within the oval fossa or in the anteo-inferior buttress, while sinus venosus defects, ostium defects and coronary sinus defects are morphologically distinct from them.<\/jats:p>","DOI":"10.18295\/squmj.12.2023.075","type":"journal-article","created":{"date-parts":[[2023,12,2]],"date-time":"2023-12-02T22:23:13Z","timestamp":1701555793000},"page":"5-9","source":"Crossref","is-referenced-by-count":0,"title":["The Sinus Venosus Veno-Venous Bridge: &lt;i&gt;Not a septal defect&lt;\/i&gt;"],"prefix":"10.18295","volume":"23","author":[{"given":"Madan M","family":"Maddali","sequence":"first","affiliation":[{"name":"Department of Cardiac Anesthesia, National Heart Center, The Royal Hospital, Muscat, Oman"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert H","family":"Anderson","sequence":"additional","affiliation":[{"name":"Institute of Genetic Medicine, Newcastle University, Newcastle, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Salim N","family":"Al Maskari","sequence":"additional","affiliation":[{"name":"Department of Pediatric Cardiology, National Heart Center, The Royal Hospital, Muscat, Oman"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Faiza","family":"Al Kindi","sequence":"additional","affiliation":[{"name":"Department of Cardiac Imaging, National Heart Center, The Royal Hospital, Muscat, Oman"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hamood N","family":"Al Kindi","sequence":"additional","affiliation":[{"name":"Department of Cardiothoracic Surgery, National Heart Center, The Royal Hospital, Muscat, Oman"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7681","published-online":{"date-parts":[[2023,11,30]]},"container-title":["Sultan Qaboos University Medical Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.squ.edu.om\/index.php\/squmj\/article\/download\/6159\/3956","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.squ.edu.om\/index.php\/squmj\/article\/download\/6159\/3957","content-type":"image\/jpeg","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.squ.edu.om\/index.php\/squmj\/article\/download\/6159\/3958","content-type":"image\/jpeg","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.squ.edu.om\/index.php\/squmj\/article\/download\/6159\/3956","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,11,3]],"date-time":"2026-11-03T09:31:53Z","timestamp":1793698313000},"score":1,"resource":{"primary":{"URL":"https:\/\/mjournal.squ.edu.om\/home\/vol23\/iss5\/2"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,11,30]]},"references-count":0,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2023,11,30]]}},"URL":"https:\/\/doi.org\/10.18295\/squmj.12.2023.075","relation":{},"ISSN":["2075-0528"],"issn-type":[{"value":"2075-0528","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,11,30]]}}}
