The loop unit was anchored to the papillary muscle using U-Clips. Each chordal loop was fixed on the prolapsed leaflet. A roller pump perfused the left ventricle. The left ventricular pressure was maintained at 250\u2009mm\u2009Hg. Morphological assessment of the loop reconstruction was performed using an endoscope.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n 10 independent chordal reconstructions were performed. In all cases, the loop unit remained anchored against pressures exceeding 250\u2009mm\u2009Hg. Upon increasing the water filling volume, rupture of a chorda tendinea occurred in 7 cases, rupture of the papillary muscle occurred in 2 cases, and left ventricle rupture occurred in 1 case. In all rupture cases, the loop unit remained anchored to the papillary muscle.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n This dynamic evaluation of the loop technique using U-Clips to anchor the loop unit to a papillary muscle showed that the loop technique using U-Clips is a safe method.<\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/0218492313478215","type":"journal-article","created":{"date-parts":[[2013,9,4]],"date-time":"2013-09-04T21:42:27Z","timestamp":1378330947000},"page":"160-164","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Dynamic evaluation of the loop technique using the U-Clip"],"prefix":"10.1177","volume":"22","author":[{"given":"Hideki","family":"Moriyama","sequence":"first","affiliation":[{"name":"Department of General and Cardiothoracic Surgery, Kanazawa University, Kanazawa, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shigeyuki","family":"Tomita","sequence":"additional","affiliation":[{"name":"Department of General and Cardiothoracic Surgery, Kanazawa University, Kanazawa, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Go","family":"Watanabe","sequence":"additional","affiliation":[{"name":"Department of General and Cardiothoracic Surgery, Kanazawa University, Kanazawa, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2013,9,4]]},"reference":[{"key":"bibr1-0218492313478215","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5223(98)70210-7"},{"key":"bibr2-0218492313478215","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.102.suppl_3.III-30"},{"key":"bibr3-0218492313478215","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-4975(00)02047-6"},{"key":"bibr4-0218492313478215","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejcts.2008.01.013"},{"key":"bibr5-0218492313478215","first-page":"21","volume":"13","author":"Kudo M","year":"2007","journal-title":"Ann Thorac Cardiovasc Surg"},{"key":"bibr6-0218492313478215","doi-asserted-by":"publisher","DOI":"10.1111\/j.1525-1594.2009.00822.x"},{"key":"bibr7-0218492313478215","doi-asserted-by":"publisher","DOI":"10.1067\/mtc.2001.112936"},{"key":"bibr8-0218492313478215","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.41.3.449"},{"key":"bibr9-0218492313478215","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2007.10.041"},{"key":"bibr10-0218492313478215","doi-asserted-by":"publisher","DOI":"10.1007\/s00595-007-3542-4"},{"key":"bibr11-0218492313478215","first-page":"503","volume":"64","author":"Seguchi R","year":"2011","journal-title":"Kyobu Geka"},{"key":"bibr12-0218492313478215","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2010.09.053"},{"key":"bibr13-0218492313478215","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2008.03.050"}],"container-title":["Asian Cardiovascular and Thoracic Annals"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0218492313478215","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/0218492313478215","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0218492313478215","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T16:28:03Z","timestamp":1777393683000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/0218492313478215"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,9,4]]},"references-count":13,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2014,2]]}},"alternative-id":["10.1177\/0218492313478215"],"URL":"https:\/\/doi.org\/10.1177\/0218492313478215","relation":{},"ISSN":["0218-4923","1816-5370"],"issn-type":[{"value":"0218-4923","type":"print"},{"value":"1816-5370","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,9,4]]}}}
