While surgical treatment for HCM is among the most technically challenging cardiac operations for acquired disease, surgery for MVO is rarely reported. A 38-year-old man was admitted to our hospital with a cough and dyspnea. Transthoracic and transesophageal echography and computed tomography revealed extensive left ventricular hypertrophy, extending from the anteroseptal wall to the apex, and marked papillary muscle hypertrophy. We underwent septal myectomy via aortotomy (Morrow procedure) and apical surgery. Extended myectomy provides the best exposure to the hypertrophied septum and improves the functional status of patients. <\/jats:p>","DOI":"10.1177\/2050313x241263704","type":"journal-article","created":{"date-parts":[[2024,6,19]],"date-time":"2024-06-19T11:42:45Z","timestamp":1718797365000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Extended septal myectomy for midventricular obstruction in hypertrophic cardiomyopathy"],"prefix":"10.1177","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7797-1345","authenticated-orcid":false,"given":"Y.","family":"Hisata","sequence":"first","affiliation":[{"name":"Division of Cardiovascular Surgery, Oita Prefectural Hospital, Oita City, Oita, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Tanigawa","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Surgery, Nagasaki University Hospital, Nagasaki City, Nagasaki, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4470-1629","authenticated-orcid":false,"given":"A.","family":"Baba","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Aso Iizuka Hospital, Iizuka City, Fukuoka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y.","family":"Koga","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Oita Prefectural Hospital, Oita City, Oita, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Muramatsu","sequence":"additional","affiliation":[{"name":"Division of Cardiology, Oita Prefectural Hospital, Oita City, Oita, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.","family":"Yamada","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Surgery, Oita Prefectural Hospital, Oita City, Oita, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,6,19]]},"reference":[{"key":"bibr1-2050313X241263704","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2013.04.073"},{"key":"bibr2-2050313X241263704","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2011.02.033"},{"key":"bibr3-2050313X241263704","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehu284"},{"key":"bibr4-2050313X241263704","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5223(19)41066-0"}],"container-title":["SAGE Open Medical Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/2050313X241263704","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/2050313X241263704","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/2050313X241263704","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,1]],"date-time":"2025-03-01T13:53:47Z","timestamp":1740837227000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/2050313X241263704"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,1]]},"references-count":4,"alternative-id":["10.1177\/2050313X241263704"],"URL":"https:\/\/doi.org\/10.1177\/2050313x241263704","relation":{},"ISSN":["2050-313X","2050-313X"],"issn-type":[{"type":"print","value":"2050-313X"},{"type":"electronic","value":"2050-313X"}],"subject":[],"published":{"date-parts":[[2024,1]]},"article-number":"2050313X241263704"}}
