She was markedly symptomatic when lying supine and resorted to prone sleeping. Chest X-ray reported as cardiomegaly. Transthoracic echocardiography was unremarkable twice. Computed tomography chest showed a dilated pulmonary artery. Transesophageal echocardiography identified a 12-mm ostium secundum atrial septal defect with mild pulmonary hypertension. The defect was closed with a cocoon device and rendered her symptom free. This case highlights the importance of timely organization of transesophageal echocardiography when transthoracic echocardiography is negative. It also illustrates marked dyspnoea could be a presentation of undiagnosed atrial septal defect with mild pulmonary hypertension. <\/jats:p>","DOI":"10.1177\/2050313x211012506","type":"journal-article","created":{"date-parts":[[2021,4,27]],"date-time":"2021-04-27T09:46:13Z","timestamp":1619516773000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Case report of an atrial septal defect with negative transthoracic echocardiography, a diagnostic challenge in a middle-aged female with marked dyspnoea"],"prefix":"10.1177","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3889-0956","authenticated-orcid":false,"given":"Chathuri","family":"Liyanapathirana","sequence":"first","affiliation":[{"name":"Provincial General Hospital, Badulla, Sri Lanka"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shashika Mihirani","family":"Arthanayake","sequence":"additional","affiliation":[{"name":"Provincial General Hospital, Badulla, Sri Lanka"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sisil","family":"Widyaratne","sequence":"additional","affiliation":[{"name":"Provincial General Hospital, Badulla, Sri Lanka"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saman","family":"Chandana","sequence":"additional","affiliation":[{"name":"Provincial General Hospital, Badulla, Sri Lanka"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danajani","family":"Senevirathne","sequence":"additional","affiliation":[{"name":"Provincial General Hospital, Badulla, Sri Lanka"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,4,27]]},"reference":[{"key":"bibr1-2050313X211012506","doi-asserted-by":"publisher","DOI":"10.1007\/s12471-013-0432-9"},{"key":"bibr2-2050313X211012506","doi-asserted-by":"publisher","DOI":"10.1016\/j.ccl.2020.04.001"},{"key":"bibr3-2050313X211012506","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.105.592055"},{"key":"bibr4-2050313X211012506","doi-asserted-by":"publisher","DOI":"10.1007\/s10554-018-1426-x"},{"issue":"1","key":"bibr5-2050313X211012506","first-page":"25","volume":"56","author":"Bastidas-L AC","year":"2015","journal-title":"Invest Clin"},{"key":"bibr6-2050313X211012506","doi-asserted-by":"publisher","DOI":"10.21037\/jtd.2019.10.53"},{"key":"bibr7-2050313X211012506","doi-asserted-by":"publisher","DOI":"10.1186\/s12968-019-0577-9"},{"key":"bibr8-2050313X211012506","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCINTERVENTIONS.108.826560"},{"key":"bibr9-2050313X211012506","doi-asserted-by":"publisher","DOI":"10.5812\/ircmj.18242"},{"key":"bibr10-2050313X211012506","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(85)90237-1"},{"key":"bibr11-2050313X211012506","first-page":"93","volume":"8","author":"Martin SS","year":"2015","journal-title":"Clin Med Insights Cardiol"},{"key":"bibr12-2050313X211012506","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen-2019-033084"},{"key":"bibr13-2050313X211012506","first-page":"1529","volume":"71","author":"Karnani NG","year":"2005","journal-title":"Am Fam Physician"},{"issue":"4","key":"bibr14-2050313X211012506","doi-asserted-by":"crossref","first-page":"488","DOI":"10.1016\/j.jacc.2018.10.038","volume":"73","author":"Doherty JU","year":"2019","journal-title":"J Am Coll Cardiol"}],"container-title":["SAGE Open Medical Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/2050313X211012506","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/2050313X211012506","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/2050313X211012506","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,2]],"date-time":"2025-03-02T06:21:37Z","timestamp":1740896497000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/2050313X211012506"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,1]]},"references-count":14,"alternative-id":["10.1177\/2050313X211012506"],"URL":"https:\/\/doi.org\/10.1177\/2050313x211012506","relation":{},"ISSN":["2050-313X","2050-313X"],"issn-type":[{"type":"print","value":"2050-313X"},{"type":"electronic","value":"2050-313X"}],"subject":[],"published":{"date-parts":[[2021,1]]},"article-number":"2050313X211012506"}}
