We present a case series of five patients with degenerated aortic bioprostheses treated with transfemoral transcatheter aortic valve implantation (TAVI).\n                    <jats:styled-content>Methods:<\/jats:styled-content>\n                    From December 2009 to May 2010, five patients with degenerated aortic valve bioprostheses (aortic valve area &lt; 1 cm\n                    <jats:sup>2<\/jats:sup>\n                    or severe aortic regurgitation), an excessive operative risk (EuroSCORE \u2265 30%), symptoms of heart failure (NYHA \u2265 III) and an internal diameter of bioprosthetic aortic valve 20.5 \u00b1 0.5 mm were included. Procedures were performed without hemodynamic support using femoral arteries. Balloon valvuloplasty with a 20\u2010mm balloon under rapid pacing was carried out before valve implantation. The 26\u2010mm CoreValve prosthesis, 18\u2010F\u2010generation (Medtronic, Minneapolis, Minnesota) was inserted retrograde under fluoroscopic guidance. Invasive and echocardiographic measurements were done immediately before and after TAVI. Clinical followup and echocardiography were performed after procedure (mean followup 72 days \u00b1 60, range: 176\u201330 days).\n                    <jats:styled-content>Results:<\/jats:styled-content>\n                    In all patients TAVI was successful with immediate decrease of transaortic peak\u2010to\u2010peak pressure (\n                    <jats:italic>P<\/jats:italic>\n                    = 0.002). Mild aortic regurgitation occurred in two patients and one patient received a new permanent pacemaker. Major adverse cardiac and cerebrovascular events did not arise. NYHA functional class improved in all patients and left ventricular ejection fraction increased (\n                    <jats:italic>P<\/jats:italic>\n                    = 0.019).\n                    <jats:styled-content>Conclusion:<\/jats:styled-content>\n                    Our experiences with the valve\u2010in\u2010valve technique using the CoreValve prosthesis suggest that transfemoral TAVI is feasible in high risk patients with degenerated aortic bioprostheses. \u00a9 2010 Wiley\u2010Liss, Inc.\n                  <\/jats:p>","DOI":"10.1002\/ccd.22738","type":"journal-article","created":{"date-parts":[[2010,9,8]],"date-time":"2010-09-08T01:31:24Z","timestamp":1283909484000},"page":"1000-1006","source":"Crossref","is-referenced-by-count":35,"title":["Transcatheter aortic valve implantation for treatment of patients with degenerated aortic bioprostheses\u2014valve\u2010in\u2010valve technique"],"prefix":"10.1002","volume":"76","author":[{"given":"Michael","family":"Gotzmann","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreas","family":"M\u00fcgge","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Waldemar","family":"Bojara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2010,11,17]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2003.11.026"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.107.698258"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2007.04.047"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1510\/icvts.2010.234625"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2009.07.006"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.109.924613"},{"key":"e_1_2_7_8_2","doi-asserted-by":"publisher","DOI":"10.1002\/ccd.21300"},{"key":"e_1_2_7_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2009.06.060"},{"key":"e_1_2_7_10_2","doi-asserted-by":"publisher","DOI":"10.2459\/JCM.0b013e32832ffcb4"},{"key":"e_1_2_7_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1010-7940(99)00106-2"},{"key":"e_1_2_7_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.euje.2005.12.014"},{"key":"e_1_2_7_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2006.03.002"},{"key":"e_1_2_7_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2009.07.013"},{"key":"e_1_2_7_15_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-130-6-199903160-00002"},{"key":"e_1_2_7_16_2","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehp575"},{"key":"e_1_2_7_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(02)02965-0"},{"key":"e_1_2_7_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2004.08.023"},{"key":"e_1_2_7_19_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2009.04.075"},{"key":"e_1_2_7_20_2","doi-asserted-by":"publisher","DOI":"10.1510\/icvts.2009.225144"},{"key":"e_1_2_7_21_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2009.01.060"}],"container-title":["Catheterization and Cardiovascular Interventions"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fccd.22738","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccd.22738","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,9]],"date-time":"2023-10-09T09:25:02Z","timestamp":1696843502000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ccd.22738"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,11,17]]},"references-count":20,"journal-issue":{"issue":"7","published-print":{"date-parts":[[2010,12]]}},"alternative-id":["10.1002\/ccd.22738"],"URL":"https:\/\/doi.org\/10.1002\/ccd.22738","archive":["Portico"],"relation":{},"ISSN":["1522-1946","1522-726X"],"issn-type":[{"value":"1522-1946","type":"print"},{"value":"1522-726X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,11,17]]}}}
