All patients underwent preoperative, pre-discharge, and annual follow-up echocardiographic evaluations.

The median mitral valve area (MVA) was 2.9 [interquartile range (IQR) 2.6\u20133.1] cm\n                      <jats:sup>2<\/jats:sup>\n                      before surgery, 2.6 (IQR 2.2\u20132.7) cm\n                      <jats:sup>2<\/jats:sup>\n                      before discharge, and 2.6 (IQR 2.2\u20132.8) cm\n                      <jats:sup>2<\/jats:sup>\n                      at the latest follow-up. There were no cases of mitral stenosis clinically. All cases showed a significant decrease in the left ventricular outflow tract pressure gradient after surgery, but one case required re-operation due to recurrent obstruction at the mid-cardiac position. SAM did not recur in any cases, and all patients were in NYHA class 1 at the latest follow-up.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The floating stitch technique showed an excellent SAM-suppression effect and durability. MVA decreased about 10% following the floating stitch technique, but sufficient area was secured without functional mitral stenosis. The combination of septal myectomy and floating stitch technique is a simple and reproducible procedure for HOCM, especially with severe SAM.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s11748-025-02167-6","type":"journal-article","created":{"date-parts":[[2025,6,12]],"date-time":"2025-06-12T11:21:40Z","timestamp":1749727300000},"page":"885-892","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Mid-term results of the floating stitch for systolic anterior motion in hypertrophic obstructive cardiomyopathy"],"prefix":"10.1007","volume":"73","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-9729-3020","authenticated-orcid":false,"given":"Tomonari","family":"Uemura","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akihiko","family":"Usui","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshiyuki","family":"Tokuda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuji","family":"Narita","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masato","family":"Mutsuga","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2025,6,12]]},"reference":[{"key":"2167_CR1","doi-asserted-by":"publisher","first-page":"984","DOI":"10.1161\/01.CIR.70.6.984","volume":"70","author":"P Spirito","year":"1984","unstructured":"Spirito P, Maron BJ, Rosing DR.
