During working mode, the left ventricular end systolic pressure volume relationship (LV ESPVR) was 23.1\u00b111.1 mmHg\/ml and the LV preload recruitable stroke work (PRSW) was 67.8\u00b17.2. (Standard PVAN analysis software) (Millar Instruments, Houston, TX, USA)<\/jats:p>\n                  <jats:p>All five hearts were perfused for 219\u00b164 minutes and regained normal cardiac function on the perfusion system.They displayed a significant upward and leftward shift of the end systolic pressure volume relationship, a significant increase in preload recruitable stroke work and minimal stiffness. These hearts could potentially be considered for transplantation. The circuit was effective during reperfusion and working modes whilst proving to be successful in maintaining cardiac function in excess of four hours. Using an autologous prime of approximately 20% haematocrit (Hct), electrolytes and blood gases were easy to control within this period using standard perfusion techniques.<\/jats:p>","DOI":"10.1177\/0267659112449035","type":"journal-article","created":{"date-parts":[[2012,6,13]],"date-time":"2012-06-13T20:56:51Z","timestamp":1339621011000},"page":"408-413","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":20,"title":["Ex vivo perfusion of the swine heart as a method for pre-transplant assessment"],"prefix":"10.1177","volume":"27","author":[{"given":"S","family":"Colah","sequence":"first","affiliation":[{"name":"Cambridge Perfusion Services, Papworth Hospital, Cambridge, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"DH","family":"Freed","sequence":"additional","affiliation":[{"name":"Department of Surgery, University of Manitoba, Winnipeg, Canada"},{"name":"National Research Council of Canada, Institute for Biodiagnostics, Winnipeg, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P","family":"Mundt","sequence":"additional","affiliation":[{"name":"Department of Surgery, University of Manitoba, Winnipeg, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S","family":"Germscheid","sequence":"additional","affiliation":[{"name":"National Research Council of Canada, Institute for Biodiagnostics, Winnipeg, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P","family":"White","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Addenbrooke\u2019s Hospital, Cambridge, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A","family":"Ali","sequence":"additional","affiliation":[{"name":"Department of Cardiac and Thoracic Surgery, Papworth Hospital, Cambridge, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G","family":"Tian","sequence":"additional","affiliation":[{"name":"Department of Surgery, University of Manitoba, Winnipeg, Canada"},{"name":"National Research Council of Canada, Institute for Biodiagnostics, Winnipeg, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S","family":"Large","sequence":"additional","affiliation":[{"name":"Department of Cardiac and Thoracic Surgery, Papworth Hospital, Cambridge, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F","family":"Falter","sequence":"additional","affiliation":[{"name":"Department of Anaesthesia and Intensive Care, Papworth Hospital, Cambridge, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2012,6,13]]},"reference":[{"key":"bibr1-0267659112449035","doi-asserted-by":"publisher","DOI":"10.1353\/ken.0.0136"},{"key":"bibr2-0267659112449035","doi-asserted-by":"publisher","DOI":"10.1080\/00015458.2008.11680174"},{"key":"bibr3-0267659112449035","doi-asserted-by":"publisher","DOI":"10.1016\/j.transproceed.2007.06.014"},{"key":"bibr4-0267659112449035","doi-asserted-by":"publisher","DOI":"10.1097\/TP.0b013e31817c87b6"},{"key":"bibr5-0267659112449035","doi-asserted-by":"publisher","DOI":"10.1016\/j.healun.2009.01.010"},{"key":"bibr6-0267659112449035","doi-asserted-by":"publisher","DOI":"10.1016\/j.thorsurg.2009.02.006"},{"key":"bibr7-0267659112449035","doi-asserted-by":"publisher","DOI":"10.1016\/j.healun.2008.12.014"},{"key":"bibr8-0267659112449035","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.4.5626.296"},{"key":"bibr9-0267659112449035","first-page":"245","volume":"8","author":"Wicomb W","year":"1981","journal-title":"S Afr Med J"},{"key":"bibr10-0267659112449035","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-4975(00)01939-1"},{"key":"bibr11-0267659112449035","unstructured":"Casey ND, Colah S, Rosengard B.
