The most common cause is a right\u2010to\u2010left intracardiac shunt at the foramen ovale (FO). This study reviews the outcomes of 11 patients who underwent percutaneous FO closure for POS at our center between 2007 and 2023. The cohort consisted of six women and five men, with a median age of 77 years. All patients had cardiovascular risk factors, particularly hypertension. Pre\u2010procedure oxygen saturation was low (median 83%), but all patients showed immediate improvement after FO closure, with a median post\u2010procedure saturation of 97%. The median length of stay before the procedure was 40 days, reflecting the diagnostic delay typical of this syndrome. Postprocedure, the median length of stay was 8 days. No complications were recorded. The study also explores the pathophysiology of POS, identifying potential risk factors such as structural changes in the heart and thoraco\u2010abdominal surgeries that may contribute to the development of this syndrome. These findings confirm that percutaneous FO closure is a safe and effective treatment for POS, offering rapid improvement in oxygen saturation and emphasizing the importance of early diagnosis.<\/jats:p>","DOI":"10.1002\/ccd.31604","type":"journal-article","created":{"date-parts":[[2025,5,20]],"date-time":"2025-05-20T07:18:18Z","timestamp":1747725498000},"page":"698-701","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Platypnea\u2010Orthodeoxia Syndrome (POS): A Retrospective Study of Percutaneous Closure of the Foramen Ovale in a Single Center"],"prefix":"10.1002","volume":"106","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8780-6781","authenticated-orcid":false,"given":"Alejandro","family":"Rasines\u2010Rodr\u00edguez","sequence":"first","affiliation":[{"name":"Pediatric Cardiology Unit, Department of Pediatrics Complejo Hospitalario Universitario A Coru\u00f1a A Coru\u00f1a Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexis","family":"Otero Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Department of Pediatrics Complejo Hospitalario Universitario A Coru\u00f1a A Coru\u00f1a Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jorge","family":"Salgado Fern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Hemodynamics Unit, Department of Cardiology Complejo Hospitalario Universitario A Coru\u00f1a A Coru\u00f1a Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fernando","family":"Rueda N\u00fa\u00f1ez","sequence":"additional","affiliation":[{"name":"Pediatric Cardiology Unit, Department of Pediatrics Complejo Hospitalario Universitario A Coru\u00f1a A Coru\u00f1a Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,5,20]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.rmed.2017.05.016"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1155\/2020\/9813038"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1161\/JAHA.121.024609"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcin.2016.07.003"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.hlc.2022.07.003"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00270-004-0035-3"}],"container-title":["Catheterization and Cardiovascular Interventions"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccd.31604","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/ccd.31604","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccd.31604","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,2,16]],"date-time":"2026-02-16T06:07:54Z","timestamp":1771222074000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ccd.31604"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,5,20]]},"references-count":6,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2025,7]]}},"alternative-id":["10.1002\/ccd.31604"],"URL":"https:\/\/doi.org\/10.1002\/ccd.31604","archive":["Portico"],"relation":{},"ISSN":["1522-1946","1522-726X"],"issn-type":[{"value":"1522-1946","type":"print"},{"value":"1522-726X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,5,20]]},"assertion":[{"value":"2025-05-05","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-05-14","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-05-20","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
