Case Presentation: A 1-month-old infant was diagnosed with incidental patent ductus venosus (PDV) and a focal nodular hyperplasia-like liver nodule. Laboratory tests revealed hyperammonemia (192 \u00b5mol\/L) and cholestasis. Imaging confirmed a 7.8-mm shunt connecting the left portal vein to the inferior vena cava. Urgent transcatheter closure was performed via the right jugular vein using a 12\/10-mm LifeTech\u2122 Konar-MFO occluder. Post-procedural imaging showed complete shunt occlusion, and ammonia levels rapidly decreased to 71.8 \u00b5mol\/L. Cholestasis improved, and the patient was discharged without complications. Conclusion: This report describes the first global use of the Konar-MFO device for PDV closure. Transcatheter embolization using this device is a safe and effective minimally invasive treatment for symptomatic PDV in young infants.<\/jats:p>","DOI":"10.1159\/neo\/adsag007","type":"journal-article","created":{"date-parts":[[2026,8,6]],"date-time":"2026-08-06T13:03:40Z","timestamp":1786021420000},"page":"1-1","source":"Crossref","is-referenced-by-count":0,"title":["The First Reported Transcatheter Closure of Patent Ductus Venosus Using the LifeTech\u2122 Konar-MFO VSD Occluder in an Infant with Hyperammonemia"],"prefix":"10.1159","author":[{"given":"Hung-Yao","family":"Yun","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hsin-Wei","family":"Chou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi-Hsuan","family":"Su","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu-Hsuan","family":"Chien","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2026,8,28]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhepr.2023.100933"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1007\/s00431-017-3058-x"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1007\/s00261-018-1619-8"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1055\/s-0032-1329896"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1097\/MPG.0000000000002263"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1097\/SLA.0000000000000266"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.3390\/children9020243"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1007\/s00246-005-1081-6"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1007\/s00246-009-9397-2"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.29934"}],"container-title":["Neonatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/neo\/adsag007","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,5]],"date-time":"2026-10-05T08:47:55Z","timestamp":1791190075000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/neo\/adsag007"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,8,28]]},"references-count":10,"URL":"https:\/\/doi.org\/10.1159\/neo\/adsag007","archive":["Portico"],"relation":{"is-supplemented-by":[{"id-type":"doi","id":"10.6084\/m9.figshare.33196950","asserted-by":"subject"}]},"ISSN":["1661-7800","1661-7819"],"issn-type":[{"value":"1661-7800","type":"print"},{"value":"1661-7819","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,8,28]]}}}
