There were 58 (65.9%) boys and 30 (34.1%) girls, with a mean age of 15.4 \u00b1 2.1 years. Mitral regurgitation was detected in 39 (44.3%) patients, and both mitral and aortic regurgitation in 15 (17%). Ball valves were inserted in 52 (59.1%) patients, bileaflet valves in 31 (35.2%), and single-disc valves in 5 (5.7%). There were 4 (4.5%) hospital deaths and 11 late deaths. Patient survival at 30 days, 3 months, 1, 5, and 10 years was 95.5%, 93.2%, 87.5%, 82.9%, and 82.9%, respectively. Mechanical valve thrombosis occurred in 4 patients; it was fatal in 3 of them. Three patients died from stroke. Severe hemorrhage required hospital admission in 4 (4.5%) patients. Mechanical valve replacement in adolescents, with careful follow-up and anticoagulation, has acceptable long-term results.<\/jats:p>","DOI":"10.1177\/021849230701500606","type":"journal-article","created":{"date-parts":[[2013,5,6]],"date-time":"2013-05-06T09:37:22Z","timestamp":1367833042000},"page":"476-481","source":"Crossref","is-referenced-by-count":9,"title":["Prosthetic Valve Replacement in Adolescents with Rheumatic Heart Disease"],"prefix":"10.1177","volume":"15","author":[{"given":"Raja P","family":"Akhtar","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abdul R","family":"Abid","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Punjab Institute of Cardiology, Lahore, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hasnain","family":"Zafar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saqib S","family":"Sheikh","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Punjab Institute of Cardiology, Lahore, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masud A","family":"Cheema","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jawad S","family":"Khan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2007,12,1]]},"reference":[{"key":"bibr1-021849230701500606","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.2003.025981"},{"key":"bibr2-021849230701500606","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(81)91400-8"},{"key":"bibr3-021849230701500606","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-4975(99)01559-3"},{"key":"bibr4-021849230701500606","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2004.07.024"},{"key":"bibr5-021849230701500606","doi-asserted-by":"publisher","DOI":"10.1016\/S1010-7940(01)00763-1"},{"key":"bibr6-021849230701500606","first-page":"25","volume":"12","author":"Erez E","year":"2003","journal-title":"J Heart Valve Dis"},{"key":"bibr7-021849230701500606","doi-asserted-by":"crossref","first-page":"e1","DOI":"10.1016\/j.jacc.2006.05.021","volume":"48","author":"Bonow RO","year":"2006","journal-title":"J Am Coll Cardiol"},{"key":"bibr8-021849230701500606","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-4975(96)00531-0"},{"key":"bibr9-021849230701500606","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2004.11.006"},{"key":"bibr10-021849230701500606","doi-asserted-by":"publisher","DOI":"10.1007\/s00392-006-0376-9"},{"key":"bibr11-021849230701500606","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5223(02)73608-8"},{"key":"bibr12-021849230701500606","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejcts.2004.12.002"},{"key":"bibr13-021849230701500606","first-page":"1849","volume":"85","author":"Long CZ","year":"2005","journal-title":"Zhoghua Yi Xue Za Zhi"},{"key":"bibr14-021849230701500606","first-page":"166","volume":"14","author":"Shanmugam G","year":"2005","journal-title":"J Heart Valve Dis"},{"key":"bibr15-021849230701500606","first-page":"158","volume":"14","author":"Shanmugam G","year":"2005","journal-title":"J Heart Valve Dis"},{"key":"bibr16-021849230701500606","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5223(19)36936-3"}],"container-title":["Asian Cardiovascular and Thoracic Annals"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/021849230701500606","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/021849230701500606","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/021849230701500606","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T15:13:26Z","timestamp":1777389206000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/021849230701500606"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,12]]},"references-count":16,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2007,12]]}},"alternative-id":["10.1177\/021849230701500606"],"URL":"https:\/\/doi.org\/10.1177\/021849230701500606","relation":{},"ISSN":["0218-4923","1816-5370"],"issn-type":[{"value":"0218-4923","type":"print"},{"value":"1816-5370","type":"electronic"}],"subject":[],"published":{"date-parts":[[2007,12]]}}}
