This study evaluates initial results and long\u2010term follow up of transcatheter stent placement in bifurcating PAs. <jats:styled-content>Methods<\/jats:styled-content>: This is a retrospective review of patients (pts) who had bifurcating PA stents placed in main and lobar branches from 1993 to 2007. <jats:styled-content>Results<\/jats:styled-content>: Forty\u2010nine pts had bifurcating PA stents placed at a median age of 10.9 years (range 1\u201343 years). The mean minimum vessel diameter increased from 5.7 \u00b1 2.5 mm to 11.0 \u00b1 3.6 mm (<jats:italic>P<\/jats:italic> &lt; 0.001), the mean gradient across the stenoses decreased from 37.0 \u00b1 26.9 to 9.2 \u00b1 13 mm Hg (<jats:italic>P<\/jats:italic> &lt; 0.001), whereas the mean RV:FA ratio decreased from 0.76 \u00b1 0.29 to 0.53 \u00b1 0.24 (<jats:italic>P<\/jats:italic> &lt; 0.001). There was one death due to severe pulmonary hemorrhage. F\/U data were available in 38 pts (mean duration 6.3 \u00b1 4.1 years, range 1.2\u201313.1 years). Thirty pts underwent repeat catheterizations (mean 2.3 \u00b1 2.2 years poststent), with 26 requiring further interventions: Fifteen had balloon angioplasty alone and 11 had additional stents placed. There were no complications at f\/u catheterization. Six pts underwent further palliative surgeries, although none for repair of branch PA stenoses. <jats:styled-content>Conclusions<\/jats:styled-content>: Simultaneous transcatheter placement of bifurcating PA stents provides immediate gradient relief of bifurcating stenoses in the proximal or lobar branch PAs and reduces RV systolic pressure. Further interventions can be safely performed in future procedures, and the presence of stents does not complicate future surgeries. \u00a9 2009 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/ccd.21838","type":"journal-article","created":{"date-parts":[[2009,2,20]],"date-time":"2009-02-20T21:54:09Z","timestamp":1235166849000},"page":"557-563","source":"Crossref","is-referenced-by-count":35,"title":["Simultaneous stent implantation to treat bifurcation stenoses in the pulmonary arteries: Initial results and long\u2010term follow up"],"prefix":"10.1002","volume":"73","author":[{"given":"Gary E.","family":"Stapleton","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rabih","family":"Hamzeh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charles E.","family":"Mullins","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas M.","family":"Zellers","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Henri","family":"Justino","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alan","family":"Nugent","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael R.","family":"Nihill","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ronald G.","family":"Grifka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frank F.","family":"Ing","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2009,2,20]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjcard.2006.05.051"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.20944"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.20723"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1583\/05-1708.1"},{"key":"e_1_2_6_6_2","first-page":"125","article-title":"Three new applications of stent technology in a single patient","volume":"28","author":"McMahon CJ","year":"2001","journal-title":"Tex Heart Inst J"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(97)00535-4"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.92.4.893"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(01)01406-1"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.67.5.962"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.77.1.188"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9149(00)01203-0"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1017\/S1047951106000679"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1017\/S1047951105001769"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.83.6.1923"},{"key":"e_1_2_6_16_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.88.2.605"},{"key":"e_1_2_6_17_2","doi-asserted-by":"publisher","DOI":"10.1017\/S1047951105001770"}],"container-title":["Catheterization and Cardiovascular Interventions"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fccd.21838","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccd.21838","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,12]],"date-time":"2023-10-12T09:39:49Z","timestamp":1697103589000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ccd.21838"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,2,20]]},"references-count":16,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2009,3]]}},"alternative-id":["10.1002\/ccd.21838"],"URL":"https:\/\/doi.org\/10.1002\/ccd.21838","archive":["Portico"],"relation":{},"ISSN":["1522-1946","1522-726X"],"issn-type":[{"value":"1522-1946","type":"print"},{"value":"1522-726X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,2,20]]}}}
