Neuroimaging confirmed an embolic right occipital infarction. Transthoracic echocardiography demonstrated early bubble passage, and transesophageal imaging identified a 4.6 mm ostium secundum atrial septal defect. The defect was successfully closed percutaneously with complete shunt resolution. This case emphasizes the value of targeted multimodality imaging in uncovering occult interatrial shunts and highlights presumed paradoxical embolism as a potential mechanism of postoperative or cryptogenic stroke.<\/jats:p>","DOI":"10.3390\/diagnostics16060907","type":"journal-article","created":{"date-parts":[[2026,3,19]],"date-time":"2026-03-19T08:54:37Z","timestamp":1773910477000},"page":"907","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Unrecognized Atrial Septal Defect Presenting with Postoperative Occipital Infarction"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2660-3558","authenticated-orcid":false,"given":"Jasper","family":"Lin","sequence":"first","affiliation":[{"name":"Department of Cardiology, Division of Specialist Medical Services, Gold Coast Hospital and Health Services, Southport, QLD 4215, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vinicius","family":"Carraro do Nascimento","sequence":"additional","affiliation":[{"name":"Department of Interventional Neuroradiology, Gold Coast University Hospital, Southport, QLD 4215, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeremy","family":"Hefford","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Division of Specialist Medical Services, Gold Coast Hospital and Health Services, Southport, QLD 4215, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tony","family":"Vo","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Division of Specialist Medical Services, Gold Coast Hospital and Health Services, Southport, QLD 4215, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9651-1109","authenticated-orcid":false,"given":"Maria Gabriela","family":"Matta","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Division of Specialist Medical Services, Gold Coast Hospital and Health Services, Southport, QLD 4215, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1247","DOI":"10.1161\/STROKEAHA.120.034019","article-title":"Posterior National Institutes of Health Stroke Scale improves prognostic accuracy in posterior circulation stroke","volume":"53","author":"Alemseged","year":"2022","journal-title":"Stroke"},{"key":"ref_2","first-page":"192","article-title":"Posterior circulation ischemic stroke","volume":"112","author":"Go","year":"2015","journal-title":"Mo.
