Patients underwent subaortic membrane resection and myectomy. During the long-term follow up, patients were evaluated with transthoracic M-mode echocardiography and 2D speckle-tracking echocardiography for functional assessment.\nResults: The mean age at operation and mean duration of follow up was 8.1\u00b15.6 years and 7.2\u00b13.3 years, respectively. Interventricular septal thickness at diastole (0.9\u00b10.1 vs. 0.8\u00b10.1 cm, P = 0.001), ejection time (285.7\u00b126.2 vs. 261.2\u00b124.3 msec, P = 0.001), and aortic strain (15.6\u00b13.7 vs. 10.5\u00b14.0, P &lt; 0.001) were significantly higher in patients. On the other hand, ejection fraction (64.9\u00b16.1 vs. 75.1\u00b15.4 %, P &lt; 0.001), fractional shortening (35.0\u00b15.1 vs. 43.7\u00b15.1, P &lt; 0.001), and corrected velocity circumferential fiber shortening (0.12\u00b10.02 vs. 0.17\u00b10.03, P &lt; 0.001) were significantly lower, when compared with the controls. Longitudinal strain value significantly differed among the groups, with patients having significantly lower strain (18.8\u00b11.8 vs. 20.1\u00b12.1, P = 0.021).\nConclusion: In patients operated for isolated discrete subaortic stenosis, aortic gradient seems to continue in the long-term, with the persistence of low longitudinal strain.<\/jats:p>","DOI":"10.1532\/hsf.3821","type":"journal-article","created":{"date-parts":[[2021,6,11]],"date-time":"2021-06-11T20:46:11Z","timestamp":1623444371000},"page":"E512-E516","source":"Crossref","is-referenced-by-count":2,"title":["Long-Term Functional Results of Patients Operated for Isolated Discrete Subaortic Stenosis"],"prefix":"10.31083","volume":"24","author":[{"given":"Veysel","family":"\u015eAH\u0130N","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Savas","family":"Demirpence","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Funda","family":"Tetik","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Faik Fevzi","family":"Okur","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emin Alp","family":"Alayunt","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"16242","published-online":{"date-parts":[[2021,6,11]]},"container-title":["The Heart Surgery Forum"],"original-title":[],"link":[{"URL":"https:\/\/journal.hsforum.com\/index.php\/HSF\/article\/download\/3821\/6749","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journal.hsforum.com\/index.php\/HSF\/article\/download\/3821\/6749","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,12,22]],"date-time":"2025-12-22T10:15:39Z","timestamp":1766398539000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.imrpress.com\/journal\/HSF\/24\/3\/10.1532\/hsf.3821"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,6,11]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2021,5,11]]}},"URL":"https:\/\/doi.org\/10.1532\/hsf.3821","relation":{},"ISSN":["1522-6662","1098-3511"],"issn-type":[{"value":"1522-6662","type":"electronic"},{"value":"1098-3511","type":"print"}],"subject":[],"published":{"date-parts":[[2021,6,11]]}}}
