On the other hand, transcatheter aortic valve replacement (TAVR) provides an excellent option to replace the aortic valve without the need for cardiopulmonary bypass. Several studies have compared TAVR to surgical aortic valve replacement (SAVR) but none have utilized a minimally invasive extracorporeal circuit.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>METHODS<\/jats:title>\n                  <jats:p>We retrospectively analysed the results of both procedures among octogenarians operated in our department from 2003 to 2016. Excluded were patients with an active endocarditis, a history of previous cardiac surgery, as well as those who had a minimally invasive surgical approach. This yielded 81 and 142 octogenarians in the SAVR and TAVR groups, respectively. To compensate for a lack of randomization, we performed a propensity score analysis, which yielded 68 patient pairs for the final analysis.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>The 30-day postoperative mortality was lower in the SAVR group (1.5% vs 5.9%) but not statistically significant (P\u2009 = 0.4). In contrast, the incidence of postoperative atrial fibrillation was lower in the TAVR group (13% vs 29%) but also non-significant (P\u2009 = 0.2). Finally, the incidence of paravalvular leakage was in favour of the SAVR group (2.9% vs 52%; P\u2009 = 0.001) while the transfusion requirement was significantly lower in the TAVR group (29% vs 72%; P\u2009&amp;lt;\u20090.001).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>SAVR utilizing a minimally invasive extracorporeal circuit improves the quality of patient care and can offer an alternative to TAVR in octogenarians.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/icvts\/ivaa066","type":"journal-article","created":{"date-parts":[[2020,3,21]],"date-time":"2020-03-21T20:08:05Z","timestamp":1584821285000},"page":"56-62","source":"Crossref","is-referenced-by-count":5,"title":["Is aortic valve replacement with a minimally invasive extracorporeal circuit a contemporary option for octogenarians?"],"prefix":"10.1093","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5583-039X","authenticated-orcid":false,"given":"Aschraf","family":"El-Essawi","sequence":"first","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Braunschweig Clinic, Braunschweig, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marco","family":"Follis","sequence":"first","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Braunschweig Clinic, Braunschweig, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ren\u00e9","family":"Brouwer","sequence":"first","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Braunschweig Clinic, Braunschweig, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ingo","family":"Breitenbach","sequence":"first","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Braunschweig Clinic, Braunschweig, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Steffen","family":"Groeger","sequence":"first","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Braunschweig Clinic, Braunschweig, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7515-0044","authenticated-orcid":false,"given":"Marcel","family":"Anssar","sequence":"first","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Braunschweig Clinic, Braunschweig, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wolfgang","family":"Harringer","sequence":"first","affiliation":[{"name":"Department of Thoracic and Cardiovascular Surgery, Braunschweig Clinic, Braunschweig, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2020,5,23]]},"reference":[{"key":"2020070114043137900_ivaa066-B1","doi-asserted-by":"crossref","first-page":"S1492","DOI":"10.21037\/jtd.2019.02.19","article-title":"MIECT: how did it start?","volume":"11","author":"Fromes","year":"2019","journal-title":"J Thorac Dis"},{"key":"2020070114043137900_ivaa066-B2","doi-asserted-by":"crossref","first-page":"436","DOI":"10.1016\/j.jtcvs.2004.01.041","article-title":"Aortic valve replacement with the minimal extracorporeal circulation (Jostra MECC System) versus standard cardiopulmonary bypass: a randomized prospective trial","volume":"128","author":"Remadi","year":"2004","journal-title":"J Thorac Cardiovasc Surg"},{"key":"2020070114043137900_ivaa066-B3","doi-asserted-by":"crossref","first-page":"470","DOI":"10.1177\/0267659111419035","article-title":"Are minimized perfusion circuits the better heart lung machines?
