It may be diagnosed late due to the presence of minimal symptoms. We report the case of a 3-year-old child who presented with dyspnea and cyanosis. Transthoracic echocardiography revealed an anomalous fistulous connection between the right pulmonary artery and a large aneurysm communicating with the roof of the left atrium. The patient underwent successful transcatheter occlusion using an atrial septal defect occluder device. The patient had an uneventful recovery on follow-up with resolution of cyanosis.<\/jats:p>","DOI":"10.3389\/fcvm.2025.1698642","type":"journal-article","created":{"date-parts":[[2026,3,2]],"date-time":"2026-03-02T11:58:40Z","timestamp":1772452720000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Case Report: Transcatheter occlusion of a rare pulmonary artery to left atrium fistula using an atrial septal defect occluder device"],"prefix":"10.3389","volume":"12","author":[{"given":"Twalib Olega","family":"Aliku","sequence":"first","affiliation":[{"name":"Department of Paediatric Cardiology, Uganda Heart Institute, Mulago Hospital Complex","place":["Kampala, Uganda"]},{"name":"Department of Paediatrics and Child Health, Uganda Christian University School of Medicine","place":["Mukono, Uganda"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nestor","family":"Mbabazi","sequence":"additional","affiliation":[{"name":"Department of Paediatric Cardiology, Uganda Heart Institute, Mulago Hospital Complex","place":["Kampala, Uganda"]},{"name":"Department of Paediatrics and Child Health, Mulago National Specialized Hospital","place":["Kampala, Uganda"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernard","family":"Obongonyinge","sequence":"additional","affiliation":[{"name":"Department of Paediatric Cardiology, Uganda Heart Institute, Mulago Hospital Complex","place":["Kampala, Uganda"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Judith","family":"Namuyonga","sequence":"additional","affiliation":[{"name":"Department of Paediatric Cardiology, Uganda Heart Institute, Mulago Hospital Complex","place":["Kampala, Uganda"]},{"name":"Department of Paediatrics and Child Health, Makerere University College of Health Sciences","place":["Kampala, Uganda"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthew","family":"Jones","sequence":"additional","affiliation":[{"name":"Department of Paediatric Cardiology, Evelina London Children\u2019s Hospital, Guy\u2019s and St Thomas NHS Foundation Trust","place":["London, United Kingdom"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sulaiman","family":"Lubega","sequence":"additional","affiliation":[{"name":"Department of Paediatric Cardiology, Uganda Heart Institute, Mulago Hospital Complex","place":["Kampala, Uganda"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shakeel A.","family":"Qureshi","sequence":"additional","affiliation":[{"name":"Department of Paediatric Cardiology, Evelina London Children\u2019s Hospital, Guy\u2019s and St Thomas NHS Foundation Trust","place":["London, United Kingdom"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,3,2]]},"reference":[{"key":"B1","first-page":"20","article-title":"Physiological studies in congenital heart disease; circulatory dynamics in the anomalies of venous return to the heart including pulmonary arteriovenous fistula","volume":"86","author":"Friedlich","year":"1950","journal-title":"Bull Johns Hopkins Hosp"},{"key":"B2","first-page":"122","article-title":"Right pulmonary artery-to-left atrium communication: a rare cause of systemic cyanosis","volume":"28","author":"Alexi-Meskishvili","year":"2001","journal-title":"Tex Heart Inst J"},{"key":"B3","doi-asserted-by":"publisher","first-page":"1056","DOI":"10.1016\/S1010-7940(97)01172-X","article-title":"Surgical treatment of a fistula between the right pulmonary artery and the left atrium: presentation of two cases and review of literature","volume":"11","author":"Zeebregts","year":"1997","journal-title":"Eur J Cardiothorac Surg"},{"key":"B4","doi-asserted-by":"publisher","first-page":"742","DOI":"10.1016\/S0022-5223(19)38227-3","article-title":"Direct communications between the right pulmonary artery and left atrium","volume":"77","author":"Ohara","year":"1979","journal-title":"J Thorac Cardiovasc Surg"},{"key":"B5","doi-asserted-by":"publisher","first-page":"100031","DOI":"10.1016\/j.jscai.2022.100031","article-title":"Transcatheter closure of a rare right pulmonary artery\u2013left atrial fistula in an adult","volume":"1","author":"Qavi","year":"2022","journal-title":"J Soc Cardiovasc Angiogr Interv"},{"key":"B6","doi-asserted-by":"publisher","first-page":"857","DOI":"10.1016\/0002-9149(74)90710-3","article-title":"Communication between left pulmonary artery and left atrium","volume":"34","author":"Nelson","year":"1974","journal-title":"Am J Cardiol"},{"key":"B7","first-page":"40","article-title":"Direct communication between left pulmonary artery and left atrium","volume":"47","author":"Sambasivam","year":"1995","journal-title":"Ind Heart J"},{"key":"B8","doi-asserted-by":"publisher","first-page":"38","DOI":"10.1016\/S0022-5223(19)41787-X","article-title":"Direct communication of the right pulmonary artery with the left atrium.
