Two determinants dominate durability: excessive posterior leaflet height, which displaces the coaptation line anteriorly and drives residual regurgitation and systolic anterior motion; and, in anterior prolapse, neochordal length, where a millimetric error produces residual prolapse, restriction or recurrence. We describe RE-LOCK and TRACK, a two-component, posterior-first protocol designed to control both reproducibly. RE-LOCK relocates the redundant posterior leaflet head towards the annular plane and anchors it to a stable posterior reference, converting a mobile prolapsing edge into a controlled hinge and establishing a low, posteriorised coaptation shelf; posterior neochordae are not used. TRACK then calibrates anterior support: expanded-polytetrafluoroethylene neochordae anchored to the papillary head are advanced against a temporary annular guide kept coplanar with the annulus, so that length is set against an anatomical reference rather than by visual estimation or ventricular loading. Complete ring annuloplasty stabilises the result, and intraoperative transoesophageal echocardiography governs any revision. By fixing the sequence, platform first and calibration second, the protocol converts individually demanding manoeuvres into a repeatable, teachable operation particularly well suited to the minimally invasive field.<\/jats:p>","DOI":"10.1093\/ejcts\/ezag211","type":"journal-article","created":{"date-parts":[[2026,8,15]],"date-time":"2026-08-15T12:46:46Z","timestamp":1786798006000},"source":"Crossref","is-referenced-by-count":0,"title":["RE-LOCK and TRACK: A Reproducible Minimally Invasive Repair for Bileaflet Mitral Disease"],"prefix":"10.1093","volume":"68","author":[{"given":"Giuseppe","family":"Nasso","sequence":"first","affiliation":[{"name":"Department of Cardiac Surgery, Santa Maria Hospital, GVM Care & Research , 70124 Bari,","place":["Italy"]},{"name":"Department of Medicine and Surgery, LUM University , Casamassima, 70010 Bari,","place":["Italy"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1149-1151","authenticated-orcid":false,"given":"Giuseppe","family":"Speziale","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Santa Maria Hospital, GVM Care & Research , 70124 Bari,","place":["Italy"]},{"name":"Department of Health and Life Sciences, European University of Rome , 00163 Rome,","place":["Italy"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,8,20]]},"reference":[{"key":"2026082420312415600_ezag211-B1","doi-asserted-by":"crossref","first-page":"323","DOI":"10.1016\/S0022-5223(19)39144-5","article-title":"Cardiac valve surgery: the French correction","volume":"86","author":"Carpentier","year":"1983","journal-title":"J Thorac Cardiovasc Surg"},{"key":"2026082420312415600_ezag211-B2","doi-asserted-by":"crossref","first-page":"728","DOI":"10.1016\/j.athoracsur.2018.04.010","article-title":"A simplified technique for complex mitral valve regurgitation by a minimally invasive approach","volume":"106","author":"Speziale","year":"2018","journal-title":"Ann Thorac Surg"},{"key":"2026082420312415600_ezag211-B3","doi-asserted-by":"crossref","first-page":"718","DOI":"10.1016\/j.athoracsur.2008.05.015","article-title":"Toward a new paradigm for the reconstruction of posterior leaflet prolapse: midterm results of the \u201crespect rather than resect\u201d approach","volume":"86","author":"Perier","year":"2008","journal-title":"Ann Thorac Surg"},{"key":"2026082420312415600_ezag211-B4","doi-asserted-by":"crossref","first-page":"ezag025","DOI":"10.1093\/ejcts\/ezag025","article-title":"Annulus-guided neochord length setting for anterior mitral leaflet repair","volume":"68","author":"Nasso","year":"2026","journal-title":"Eur J Cardiothorac Surg"},{"key":"2026082420312415600_ezag211-B5","doi-asserted-by":"crossref","first-page":"4517","DOI":"10.1111\/jocs.17108","article-title":"A new technique to adjust the length of artificial chordae during mitral anterior leaflet repair","volume":"37","author":"Nasso","year":"2022","journal-title":"J Card Surg"}],"container-title":["European Journal of Cardio-Thoracic Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/ejcts\/advance-article-pdf\/doi\/10.1093\/ejcts\/ezag211\/70665780\/ezag211.pdf","content-type":"application\/pdf","content-version":"am","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/ejcts\/article-pdf\/68\/8\/ezag211\/70665780\/ezag211.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/ejcts\/article-pdf\/68\/8\/ezag211\/70665780\/ezag211.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,25]],"date-time":"2026-08-25T00:31:28Z","timestamp":1787617888000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/ejcts\/article\/doi\/10.1093\/ejcts\/ezag211\/8762632"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,8]]},"references-count":5,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2026,8,3]]}},"URL":"https:\/\/doi.org\/10.1093\/ejcts\/ezag211","relation":{},"ISSN":["1010-7940","1873-734X"],"issn-type":[{"value":"1010-7940","type":"print"},{"value":"1873-734X","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2026,8]]},"published":{"date-parts":[[2026,8]]},"article-number":"ezag211"}}
