We present a tricuspidization technique based on selective replacement of a dysplastic cusp with autologous pericardium and creation of two neocommissures to restore symmetric leaflet closure. The operation converts a functionally unicuspid valve into a tricuspid configuration while preserving native leaflet tissue. In the presented case, the repair resulted in competent valve function with low transvalvular gradient at follow-up. This technique may serve as a growth-preserving strategy to postpone definitive valve replacement in selected paediatric patients.<\/jats:p>","DOI":"10.1510\/mmcts.2026.063","type":"journal-article","created":{"date-parts":[[2026,9,9]],"date-time":"2026-09-09T13:57:46Z","timestamp":1788962266000},"source":"Crossref","is-referenced-by-count":0,"title":["Tricuspidization of a unicuspid aortic valve in an adolescent using selective single-cusp replacement"],"prefix":"10.1510","member":"10966","published-online":{"date-parts":[[2026,9,9]]},"container-title":["Multimedia Manual of Cardio-Thoracic Surgery"],"original-title":[],"deposited":{"date-parts":[[2026,9,9]],"date-time":"2026-09-09T13:57:46Z","timestamp":1788962266000},"score":1,"resource":{"primary":{"URL":"https:\/\/mmcts.org\/tutorial\/2232"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,9,9]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1510\/mmcts.2026.063","relation":{},"ISSN":["1813-9175"],"issn-type":[{"value":"1813-9175","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,9,9]]}}}
