Following improvement in heart failure, he was discharged home independently 2 weeks postprocedure. However, 4 months ago, he experienced worsening heart failure, and echocardiography revealed recurrent severe MR due to single leaflet device attachment (SLDA) at P1, prompting a surgical intervention. Intraoperatively, after establishing cardiopulmonary bypass and inducing cardiac arrest, transseptal access revealed the MitraClip NT\ufe0e firmly adhered to the P1 leaflet and extensive rupture of the A1 chordae. The MitraClip NT\ufe0e and involved leaflet tissue were excised en bloc, the defect was repaired, artificial chordae were implanted, edge\u2010to\u2010edge repair of the AC region was performed, and a prosthetic annuloplasty ring was sutured in place, successfully eliminating regurgitation. Since MitraClip NT\ufe0e becomes encapsulated by fibrous tissue within 2\u20133 months postimplantation, isolated removal becomes technically difficult in the late phase. Therefore, en bloc resection with the leaflet is necessary in cases of SLDA\u2010related recurrent MR. SLDA involving the posterior mitral leaflet is considered more amenable to mitral valve repair than that involving the anterior mitral leaflet. Patients selected for TEER generally have limited surgical tolerance; thus, minimizing operative and cardiopulmonary bypass times is essential. Surgical approach should be tailored based on leaflet morphology and clip location.<\/jats:p>","DOI":"10.1155\/cric\/6112171","type":"journal-article","created":{"date-parts":[[2026,6,22]],"date-time":"2026-06-22T09:24:35Z","timestamp":1782120275000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Successful Mitral Valve Repair for Single Leaflet Device Attachment Following Transcatheter Edge\u2010to\u2010Edge Repair: A Case Report"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0989-0647","authenticated-orcid":false,"given":"Takuro","family":"Makiura","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4823-3172","authenticated-orcid":false,"given":"Masahiro","family":"Daimon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0967-1201","authenticated-orcid":false,"given":"Takahiro","family":"Katsumata","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,6,22]]},"reference":[{"key":"e_1_2_11_1_2","doi-asserted-by":"publisher","DOI":"10.1253\/circj.CJ-20-0135"},{"key":"e_1_2_11_2_2","doi-asserted-by":"crossref","DOI":"10.1093\/ejcts\/ezaf179","article-title":"Mitral Valve Surgery After Failed Transcatheter Intervention for Mitral Regurgitation: Surgical Techniques, Challenges and Outcomes","volume":"67","author":"Mateo M.","year":"2025","journal-title":"European Journal of Cardio-Thoracic Surgery"},{"key":"e_1_2_11_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaccas.2023.101747"},{"key":"e_1_2_11_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2018.04.010"},{"key":"e_1_2_11_5_2","doi-asserted-by":"publisher","DOI":"10.1161\/JAHA.122.026236"},{"key":"e_1_2_11_6_2","doi-asserted-by":"publisher","DOI":"10.14503\/THIJ-13-3626"}],"container-title":["Case Reports in Cardiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/cric\/6112171","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1155\/cric\/6112171","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/cric\/6112171","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,6,22]],"date-time":"2026-06-22T09:24:36Z","timestamp":1782120276000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1155\/cric\/6112171"}},"subtitle":[],"editor":[{"given":"Satabdi","family":"Datta Choudhury","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"editor"}]}],"short-title":[],"issued":{"date-parts":[[2026,1]]},"references-count":6,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2026,1]]}},"alternative-id":["10.1155\/cric\/6112171"],"URL":"https:\/\/doi.org\/10.1155\/cric\/6112171","archive":["Portico"],"relation":{},"ISSN":["2090-6404","2090-6412"],"issn-type":[{"value":"2090-6404","type":"print"},{"value":"2090-6412","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,1]]},"assertion":[{"value":"2025-09-20","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-06-04","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-06-22","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"6112171"}}
