The use of UHP balloons in patients with congenital heart disease is mostly for dilation of the pulmonary artery, and there have been few reports on the effectiveness and safety of balloons for other sites. We retrospectively evaluated the efficacy and safety of the ultra-high-pressure balloon angioplasty (UHP-BA) for stenotic lesions in patients with congenital heart disease between January 2020 and December 2022 at Okayama University Hospital. A total of 78 UHP-BAs were performed in 44 patients, with a median age of 6.6\u00a0years and a median weight of 17.6\u00a0kg. The balloon types used in the UHP-BAs were Yoroi<jats:sup>\u00ae<\/jats:sup> and Conquest<jats:sup>\u00ae<\/jats:sup>. UHP-BA performed 39 procedures for the pulmonary artery (PA), 24 for fenestration, 8 for SVC, 4 for shunt, and three for others. The lesion-specific acute procedural success rates for PA, Fontan fenestration, SVC, and shunt were 77%, 75%, 88%, and 75%, respectively. A complication of UHP-BA occurred in 3.8% (3\/78). Two of the three patients had pulmonary hemorrhage, and the remaining patients had pulmonary artery embolization due to the migration of a thrombus. There were no fatal complications. Balloon dilation with UHP balloons was safe and effective not only for pulmonary artery stenotic lesions but also for SVC, Fontan fenestration, shunt, and other dilation sites in patients with congenital heart disease.<\/jats:p>","DOI":"10.1007\/s00380-025-02547-1","type":"journal-article","created":{"date-parts":[[2025,5,6]],"date-time":"2025-05-06T14:49:50Z","timestamp":1746542990000},"page":"953-960","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Outcomes of ultra-high-pressure balloon angioplasty for congenital heart disease in single-center experience"],"prefix":"10.1007","volume":"40","author":[{"given":"Maiko","family":"Kondo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshihiko","family":"Kurita","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yosuke","family":"Fukushima","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yusuke","family":"Shigemitsu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenta","family":"Hirai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuya","family":"Kawamoto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mayuko","family":"Hara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomoyuki","family":"Kanazawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tatsuo","family":"Iwasaki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yasuhiro","family":"Kotani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shingo","family":"Kasahara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hirokazu","family":"Tsukahara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2716-5185","authenticated-orcid":false,"given":"Kenji","family":"Baba","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2025,5,6]]},"reference":[{"key":"2547_CR1","doi-asserted-by":"publisher","first-page":"1109","DOI":"10.1016\/0735-1097(90)90250-S","volume":"15","author":"AR Rothman","year":"1990","unstructured":"Rothman AR, Perry SB, Keane J, Lock JE (1990) Early results and follow-up of balloon angioplasty for branch pulmonary stenosis.
