Retaining the prosthesis may predispose to leaflet immobility, thrombosis, and inflow obstruction, whereas full prosthetic replacement adds substantial operative risk, particularly in redo cardiac surgery. We describe a novel surgical strategy combining removal of the mobile prosthetic components with preservation of the sewing ring during HeartMate 3 implantation. A 49-year-old woman with advanced heart failure and previous mechanical mitral valve replacement underwent HeartMate 3 implantation with concomitant tricuspid annuloplasty. The prosthetic leaflets and visible pivot components were intentionally fractured and removed, while the sewing ring was preserved in situ. At 12-month follow-up, the patient remained clinically stable without thromboembolic events, device malfunction, or inflow obstruction. This strategy may represent a feasible alternative to complete prosthetic replacement in selected redo patients.<\/jats:p>","DOI":"10.1093\/jscr\/rjag549","type":"journal-article","created":{"date-parts":[[2026,7,6]],"date-time":"2026-07-06T21:51:40Z","timestamp":1783374700000},"source":"Crossref","is-referenced-by-count":0,"title":["HeartMate 3 implantation in a patient with mechanical mitral valve prosthesis: intentional leaflet fracture and sewing ring preservation"],"prefix":"10.1093","volume":"2026","author":[{"given":"Denyan","family":"Mansuroglu","sequence":"first","affiliation":[{"name":"Department of Cardiovascular Surgery, Gaziosmanpasa Hospital, Istinye University, Faculty of Medicine , Gaziosmanpasa, Istanbul ,","place":["Turkey"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ali","family":"Dogan","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Gaziosmanpasa Hospital, Istinye University, Faculty of Medicine , Gaziosmanpasa, Istanbul ,","place":["Turkey"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,7,6]]},"reference":[{"key":"2026070617513169400_ref1","doi-asserted-by":"publisher","first-page":"1618","DOI":"10.1056\/NEJMoa1900486","article-title":"A fully magnetically levitated left ventricular assist device - final report","volume":"380","author":"Mehra","year":"2019","journal-title":"N Engl J Med"},{"key":"2026070617513169400_ref2","doi-asserted-by":"publisher","first-page":"e1","DOI":"10.1016\/j.healun.2023.07.015","article-title":"The 2023 International Society for Heart and Lung Transplantation guidelines for mechanical circulatory support: a 10-year update","volume":"42","author":"Saeed","year":"2023","journal-title":"J Heart Lung Transplant"},{"key":"2026070617513169400_ref3","doi-asserted-by":"publisher","first-page":"215","DOI":"10.1161\/CIRCHEARTFAILURE.113.000473","article-title":"Valvular heart disease in patients supported with left ventricular assist devices","volume":"7","author":"Wang","year":"2014","journal-title":"Circ Heart Fail"},{"key":"2026070617513169400_ref4","doi-asserted-by":"publisher","first-page":"101","DOI":"10.1007\/s12055-023-01567-8","article-title":"Managing valvular pathology during LVAD implantation","volume":"39","author":"Carr","year":"2023","journal-title":"Indian J Thorac Cardiovasc Surg"},{"key":"2026070617513169400_ref5","doi-asserted-by":"publisher","first-page":"105710","DOI":"10.1016\/j.jaccas.2025.105710","article-title":"Unpredictable mechanical mitral valve leaflet motion in a patient with continuous-flow LVAD","volume":"30","author":"Khatri","year":"2025","journal-title":"JACC Case Rep"},{"key":"2026070617513169400_ref6","doi-asserted-by":"publisher","first-page":"1316","DOI":"10.1016\/j.jtcvs.2009.11.020","article-title":"Right ventricular failure in patients with the HeartMate II continuous-flow left ventricular assist device: incidence, risk factors, and effect on outcomes","volume":"139","author":"Kormos","year":"2010","journal-title":"J Thorac Cardiovasc Surg"},{"key":"2026070617513169400_ref7","doi-asserted-by":"publisher","first-page":"644","DOI":"10.1093\/ejcts\/ezy150","article-title":"Left ventricular assist device implantation with and without concomitant tricuspid valve surgery: a systematic review and meta-analysis","volume":"54","author":"Veen","year":"2018","journal-title":"Eur J Cardiothorac Surg"},{"key":"2026070617513169400_ref8","doi-asserted-by":"publisher","first-page":"644","DOI":"10.1093\/ejcts\/ezy150","article-title":"Left ventricular assist device implantation with and without concomitant tricuspid valve surgery: a systematic review and meta-analysis","volume":"54","author":"Veen","year":"2018","journal-title":"Eur J Cardiothorac Surg"},{"key":"2026070617513169400_ref9","doi-asserted-by":"publisher","first-page":"35","DOI":"10.1186\/1742-4682-10-35","article-title":"Numerical investigation of the effect of cannula placement on thrombosis","volume":"10","author":"Ong","year":"2013","journal-title":"Theor Biol Med Model"},{"key":"2026070617513169400_ref10","doi-asserted-by":"publisher","first-page":"9","DOI":"10.1055\/s-0033-1351116","article-title":"Mitral valve and short-term ventricular assist devices;
