We report an unusual case of an aortopulmonary fistula secondary to an aortic injury sustained during mitral valve replacement, which was identified during follow-up because of recurrent heart failure symptoms and repeated hospital admissions. Multimodality imaging enabled precise characterization of the fistula. After a Heart Team discussion, percutaneous closure was selected as the preferred treatment strategy. Based on the assessment of the trajectory and morphology of the fistula, a patent ductus arteriosus (PDA) occluder was chosen. Although the ostium of the fistula was challenging to identify, successful closure was achieved using the PDA occluder.<\/jats:p>","DOI":"10.3389\/fcvm.2025.1664133","type":"journal-article","created":{"date-parts":[[2025,12,3]],"date-time":"2025-12-03T06:39:31Z","timestamp":1764743971000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Aortopulmonary fistula following mitral valve replacement: a case report"],"prefix":"10.3389","volume":"12","author":[{"given":"N\u00e1gila Simon","family":"Ziebell","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luiz Felipe","family":"Perin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Raul","family":"Rossi Filho","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Estela Suzana Kleiman","family":"Horowitz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9 Luiz da Costa","family":"Vieira","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F\u00e1bio Vieira","family":"Caovilla","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rogerio Eduardo Gomes","family":"Sarmento Leite","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2025,12,3]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1335","DOI":"10.1148\/rg.2021210004","article-title":"Aortic fistulas: pathophysiologic features, imaging findings, and diagnostic pitfalls","volume":"41","author":"Gulati","year":"2021","journal-title":"Radiographics"},{"key":"B2","doi-asserted-by":"publisher","first-page":"1833","DOI":"10.1016\/s0003-4975(99)00754-7","article-title":"A review of aortopulmonary fistulas in aortic dissection","volume":"68","author":"Picich\u00e9","year":"1999","journal-title":"Ann Thorac Surg"},{"key":"B3","doi-asserted-by":"publisher","first-page":"9088024","DOI":"10.1155\/2021\/9088024","article-title":"An unusual case of an acquired aortopulmonary fistula after surgical replacement of a bicuspid aortic valve","volume":"2021","author":"Khalid","year":"2021","journal-title":"Case Rep Cardiol"},{"key":"B4","doi-asserted-by":"publisher","first-page":"713","DOI":"10.1093\/oxfordjournals.eurheartj.a060240","article-title":"Acquired aorto-pulmonary fistula in acute dissection","volume":"13","author":"Veerbeek","year":"1992","journal-title":"Eur Heart J"},{"key":"B5","doi-asserted-by":"publisher","first-page":"73","DOI":"10.1007\/s10140-016-1433-y","article-title":"The red connection: a review of aortic and arterial fistulae with an emphasis on CT findings","volume":"24","author":"Sipe","year":"2017","journal-title":"Emerg Radiol"},{"key":"B6","first-page":"483","article-title":"Aortopulmonary fistula: a rare complication of an aortic aneurysm","volume":"36","author":"Dixit","year":"2009","journal-title":"Tex Heart Inst J"},{"key":"B7","doi-asserted-by":"publisher","first-page":"29","DOI":"10.4103\/jcecho.jcecho_5_20","article-title":"Post-traumatic aortopulmonary fistula after Bentall procedure","volume":"30","author":"Izzo","year":"2020","journal-title":"J Cardiovasc Echogr"},{"key":"B8","doi-asserted-by":"publisher","first-page":"97A","DOI":"10.1378\/chest.10300","article-title":"Acquired aorta-pulmonary artery fistula diagnosed by multidetector computed tomography","volume":"138","author":"Wellikoff","year":"2010","journal-title":"Chest"},{"key":"B9","first-page":"821","article-title":"Acquired aortopulmonary fistula.
