However, suboptimal THV expansion with consecutive paravalvular leakage (PVL) is a procedure-immanent issue.<\/jats:p><jats:p>\n            Methods\u2003A rigid, saddle-shaped ring was cut at four locations. The segments were reconnected with pull-springs, rearranged to the original shape, and covered with a sewing cuff. The length of the annuloplasty ring construct, including extended pull-springs, was defined by the perimeter of an appropriate THV. We deployed a Sapien XT within the new ring, expanded it to its maximum extent, and investigated the geometrical changes.<\/jats:p><jats:p>\n            Results\u2003Fluoroscopy confirmed oval, saddle-shaped ring before dilation. After THV implantation, the ring segments spread apart and pull-springs were stretched. The extended ring changed its configuration from \u201coval\u201d to \u201cround\u201d and anchored the THV leaving no paravalvular or central gaps as potential source for PVL.<\/jats:p><jats:p>\n            Conclusion\u2003We developed an expandable annuloplasty ring that is perfectly concerted to THV implantation. This proof-of-concept study revealed no PVL and good oversizing ability that might impact future annuloplasty ring design. Further studies have to evaluate durability and device safety.<\/jats:p>","DOI":"10.1055\/s-0037-1598029","type":"journal-article","created":{"date-parts":[[2017,2,10]],"date-time":"2017-02-10T23:38:34Z","timestamp":1486769914000},"page":"460-466","source":"Crossref","is-referenced-by-count":1,"title":["New Mitral Annuloplasty Ring Enables Oversizing of Transcatheter Heart Valve and Prevents Central or Paravalvular Leakage"],"prefix":"10.1055","volume":"65","author":[{"given":"Jan-Malte","family":"Sinning","sequence":"first","affiliation":[{"name":"Department of Medicine II\u2014Cardiology, University Heart Center Bonn, Bonn, Nordrhein-Westfalen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Armin","family":"Welz","sequence":"first","affiliation":[{"name":"Department of Cardiac Surgery, University Heart Center Bonn, Bonn, Nordrhein-Westfalen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fritz","family":"Mellert","sequence":"first","affiliation":[{"name":"Department of Cardiac Surgery, University Heart Center Bonn, Bonn, Nordrhein-Westfalen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Georg","family":"Duerr","sequence":"additional","affiliation":[{"name":"Department of Cardiac Surgery, University Heart Center Bonn, Bonn, Nordrhein-Westfalen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2017,2,10]]},"container-title":["The Thoracic and Cardiovascular Surgeon"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0037-1598029.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,12,19]],"date-time":"2017-12-19T11:02:29Z","timestamp":1513681349000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0037-1598029"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,2,10]]},"references-count":0,"journal-issue":{"issue":"06","published-online":{"date-parts":[[2017,9,6]]},"published-print":{"date-parts":[[2017,9]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0037-1598029","relation":{},"ISSN":["0171-6425","1439-1902"],"issn-type":[{"value":"0171-6425","type":"print"},{"value":"1439-1902","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,2,10]]}}}
