We report the case of a high-risk patient with extremely severe mitral insufficiency and difficult-to-debride annular calcification who received mitral replacement using a chimney technique. This approach enabled not only the minimization of mitral calcification debridement but also the reduction of surgery time. Consequently, the surgery was successful with a great postoperative outcome. Thus, this technique is a safe and feasible option to deal with intractable mitral annular calcification during mitral valve surgery.<\/jats:p>","DOI":"10.1532\/hsf.5015","type":"journal-article","created":{"date-parts":[[2022,10,12]],"date-time":"2022-10-12T22:51:02Z","timestamp":1665615062000},"page":"E718-E720","source":"Crossref","is-referenced-by-count":2,"title":["Mitral Valve Replacement Adopting Chimney Technique in Mitral Insufficiency And Extensive Mitral Annular Calcification: A Case Report"],"prefix":"10.31083","volume":"25","author":[{"given":"Jianrui","family":"Ma","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tong","family":"Tan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaohua","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiaoyang","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhen","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haiyun","family":"Yuan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"16242","published-online":{"date-parts":[[2022,10,12]]},"container-title":["The Heart Surgery Forum"],"original-title":[],"link":[{"URL":"https:\/\/journal.hsforum.com\/index.php\/HSF\/article\/download\/5015\/7615","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journal.hsforum.com\/index.php\/HSF\/article\/download\/5015\/7615","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,12,22]],"date-time":"2025-12-22T10:16:19Z","timestamp":1766398579000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.imrpress.com\/journal\/HSF\/25\/5\/10.1532\/hsf.5015"}},"subtitle":["Chimney Technique in Extensive Mitral Annular Calcification"],"short-title":[],"issued":{"date-parts":[[2022,10,12]]},"references-count":0,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2022,9,12]]}},"URL":"https:\/\/doi.org\/10.1532\/hsf.5015","relation":{},"ISSN":["1522-6662","1098-3511"],"issn-type":[{"value":"1522-6662","type":"electronic"},{"value":"1098-3511","type":"print"}],"subject":[],"published":{"date-parts":[[2022,10,12]]}}}
