Congestive heart failure and\/or cyanosis were present in 55%, 46% prostaglandin dependent, with 28% having a hypoplastic right ventricle. The pulmonary valve diameter median <jats:italic>z<\/jats:italic>\u2010score was \u22122.6, (range \u22125.8 to 1.2, <jats:italic>P<\/jats:italic> &lt; 0.0001 vs. normal). The procedure was accomplished in all but one child, using a balloon to annulus ratio of 1.3 (range 1.1 to 1.7). There was a reduction in both the peak right ventricular systolic pressure (<jats:italic>P<\/jats:italic> &lt; 0.0001) and outflow gradient (<jats:italic>P<\/jats:italic> &lt; 0.0001). There was no procedure related mortality, although six children died in long\u2010term follow\u2010up (14%). Reintervention was necessary in 15 infants within 8 months of the procedure. Pulmonary regurgitation, present in 36% after the procedure, showed a gradual increase over time while outflow gradients decreased and valve annular dimensions increased toward normal. <jats:styled-content>Conclusions<\/jats:styled-content>: In infants <jats:bold>\u22643 kg<\/jats:bold>, PVD is safe and effective. A large proportion remains free from surgery (76% at 10 years). Small valve annular dimensions show catch up growth with time. \u00a9 2009 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/ccd.22064","type":"journal-article","created":{"date-parts":[[2009,3,24]],"date-time":"2009-03-24T19:19:11Z","timestamp":1237922351000},"page":"753-761","source":"Crossref","is-referenced-by-count":22,"title":["Balloon dilation of pulmonary valve stenosis in infants less than 3 kg: A 20\u2010year experience"],"prefix":"10.1002","volume":"74","author":[{"given":"Tevfik","family":"Karagoz","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kentaro","family":"Asoh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edward","family":"Hickey","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rajiv","family":"Chaturvedi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyong\u2010Jin","family":"Lee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Nykanen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lee","family":"Benson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2009,6,3]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM198208263070907"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(95)00477-7"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.20982"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.1810340307"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/0003-4975(90)90149-Z"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.66.2.266"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(97)00031-4"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(93)90727-I"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.57.4.364"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(93)90833-M"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-8703(96)90187-8"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(84)90140-5"},{"key":"e_1_2_6_14_2","first-page":"326","article-title":"Critical pulmonary stenosis in the neonate: Role of transcatheter management","volume":"8","author":"Jureidini SB","year":"1996","journal-title":"J Invasive Cardiol"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(95)00515-3"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.63.6.362"},{"key":"e_1_2_6_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(93)90783-W"},{"key":"e_1_2_6_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(88)90217-3"},{"key":"e_1_2_6_19_2","doi-asserted-by":"publisher","DOI":"10.1053\/hj.1998.v136.89576"},{"key":"e_1_2_6_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9149(97)00028-3"},{"key":"e_1_2_6_21_2","first-page":"318","article-title":"Late outcomes after pulmonary valve balloon dilatation in neonates, infants and children","volume":"17","author":"Garty Y","year":"2005","journal-title":"J Invasive Cardiol"}],"container-title":["Catheterization and Cardiovascular Interventions"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fccd.22064","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccd.22064","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,16]],"date-time":"2023-10-16T14:48:39Z","timestamp":1697467719000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ccd.22064"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,6,3]]},"references-count":20,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2009,11]]}},"alternative-id":["10.1002\/ccd.22064"],"URL":"https:\/\/doi.org\/10.1002\/ccd.22064","archive":["Portico"],"relation":{},"ISSN":["1522-1946","1522-726X"],"issn-type":[{"value":"1522-1946","type":"print"},{"value":"1522-726X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,6,3]]}}}
