To date, valve-sparing root replacement is frequently done in patients with bi- and tricuspid aortic valve pathologies with preserved cusp tissue. Nevertheless, little is known about quadricuspid repair, especially in regard to the optimal surgical technique for long-term durability. We hereby provide a surgical guide to valve-sparing aortic root replacement using the David technique in a young patient with severe aortic regurgitation.<\/jats:p>","DOI":"10.1510\/mmcts.2022.022","type":"journal-article","created":{"date-parts":[[2022,11,2]],"date-time":"2022-11-02T16:10:43Z","timestamp":1667405443000},"source":"Crossref","is-referenced-by-count":0,"title":["The David procedure for quadricuspid aortic valve repair"],"prefix":"10.1510","author":[{"given":"Tim","family":"Berger","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10966","published-online":{"date-parts":[[2022,5,15]]},"container-title":["Multimedia Manual of Cardio-Thoracic Surgery"],"original-title":[],"deposited":{"date-parts":[[2022,11,2]],"date-time":"2022-11-02T16:10:46Z","timestamp":1667405446000},"score":1,"resource":{"primary":{"URL":"https:\/\/mmcts.org\/case-report\/1731"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,5,15]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1510\/mmcts.2022.022","relation":{},"ISSN":["1813-9175"],"issn-type":[{"value":"1813-9175","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,5,15]]}}}
