Even with satisfactory results, repair techniques may underlie subjectivity and variability and require long learning curves. A novel approach, the \u201cRoman Arch\u201d technique, may ease the technical burden. This study assessed an automated suturing device\u2019s feasibility and time efficiency for a proposed simplified technique. (2) Materials and Methods: Using the MiStitch\u2122 and MiKnot\u2122 devices (LSI Solutions, Inc., Victor, NY, USA), the suture pattern was performed in a cadaver model. Three surgeons with different expertise levels conducted the procedures. Repair and suture placement times were recorded and analyzed. (3) Results: The modified \u201cRoman Arch\u201d repair was completed on all ten human heart specimens with an average total repair time of 3:01 \u00b1 00:59 min and a trend toward reduced times as experience increased. The study confirmed the technical feasibility with 90% of the attempts rated as rather satisfactory or very satisfactory. (4) Conclusions: The MiStitch\u2122 system effectively facilitated the modified \u201cRoman Arch\u201d repair in an ex vivo setting, suggesting its potential to reduce the technical complexity of mitral valve repairs. Further studies are needed to confirm its efficacy and safety in clinical practice.<\/jats:p>","DOI":"10.3390\/medicina60071138","type":"journal-article","created":{"date-parts":[[2024,7,15]],"date-time":"2024-07-15T12:44:36Z","timestamp":1721047476000},"page":"1138","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Innovative Mitral Valve Repair Using a Novel Automated Suturing System: Preliminary Data"],"prefix":"10.3390","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0374-8375","authenticated-orcid":false,"given":"Thomas","family":"Poschner","sequence":"first","affiliation":[{"name":"Department of Cardiac Surgery, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Severin","family":"Laengle","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-0121-2734","authenticated-orcid":false,"given":"Sahra","family":"Tasdelen","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-6940-2522","authenticated-orcid":false,"given":"Aldo","family":"Suria","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Funda","family":"Baysal","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alfred","family":"Kocher","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin","family":"Andreas","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, Medical University of Vienna, 1090 Vienna, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,15]]},"reference":[{"key":"ref_1","unstructured":"Herold, G.
