As there are no published randomized clinical trials comparing outcomes with and without a monocusp valve, we performed a meta-analysis of observational studies in accordance with established protocols. After systematically searching PubMed, the Cochrane Library, and Google Scholar, 12 studies were included. The operative mortality was compared in 695 patients, and we found no difference between patients with and patients without a monocusp valve. Monocusp valves may not improve operative mortality of tetralogy of Fallot repair in pediatric patients.<\/jats:p>","DOI":"10.1177\/2150135120934763","type":"journal-article","created":{"date-parts":[[2020,8,27]],"date-time":"2020-08-27T16:21:44Z","timestamp":1598545304000},"page":"619-624","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Monocusp Valves Do Not Improve Early Operative Mortality in Tetralogy of Fallot: A Meta-Analysis"],"prefix":"10.1177","volume":"11","author":[{"given":"Mark N.","family":"Awori","sequence":"first","affiliation":[{"name":"Department of Surgery, School of Medicine, University of Nairobi, Kenyatta National Hospital, Nairobi, Kenya"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonathan A.","family":"Awori","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Seattle Children\u2019s Hospital, Seattle, WA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nikita P.","family":"Mehta","sequence":"additional","affiliation":[{"name":"Department of Surgery, School of Medicine, University of Nairobi, Kenyatta National Hospital, Nairobi, Kenya"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Obed","family":"Makori","sequence":"additional","affiliation":[{"name":"Department of Surgery, School of Medicine, University of Nairobi, Kenyatta National Hospital, Nairobi, Kenya"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2020,8,27]]},"reference":[{"key":"bibr1-2150135120934763","doi-asserted-by":"publisher","DOI":"10.1093\/ejcts\/ezs372"},{"key":"bibr2-2150135120934763","doi-asserted-by":"publisher","DOI":"10.1093\/ejcts\/ezs479"},{"key":"bibr3-2150135120934763","doi-asserted-by":"publisher","DOI":"10.1177\/0218492312444284"},{"key":"bibr4-2150135120934763","doi-asserted-by":"publisher","DOI":"10.1111\/chd.12670"},{"key":"bibr5-2150135120934763","doi-asserted-by":"publisher","DOI":"10.1001\/jama.283.15.2008"},{"key":"bibr6-2150135120934763","unstructured":"Open Science Framework (OSF) (2011).
