One of the significant aspects of this increased co-morbidity, which affects both short- and long-term outcomes, is compromised left ventricular function. Intra-aortic balloon pump (IABP) technology offers these patients and the cardiac team an easily accessible, cost-effective, mechanical assist device.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Arterial pressure monitoring for IABP therapy:<\/jats:title>\n                    <jats:p>Fluid-filled transducers used to measure the aortic waveform can be unreliable and inconsistent. Fiber-optic manometers located in the very tip of the IAB catheters provide accurate and fast, high quality measurements. This, in turn, presents the opportunity for the hardware and algorithm to measure key markers on the arterial waveform and optimise left ventricular support. It also provides the potential for automatic in vivo calibration, further increasing the accuracy and quality of the IAB support.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>The effect of fiber-optic IABP therapy on clinical management:<\/jats:title>\n                    <jats:p>A dual centre prospective audit comparing fluid-filled versus fiber-optic arterial pressure monitoring showed a 96% reduction in IAB-related perfusion on-site call-outs (17 vs. 1, respectively) and a 94% reduction in sub-optimal timing (55\/98 vs. 2\/94, respectively).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The improved timing algorithms utilise the pressure information received 50 msecs faster than with fluid-filled transducers, measuring key markers on the pressure waveform and adjusting inflation and deflation accurately on a beat per beat basis. Fiber-optic IAB technology and, specifically, these improved algorithms provide better beat per beat mechanical support. Given our evolving patient population, this technology will not only play an increased role, but will have a significant impact on cardiac surgery.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/0267659112454156","type":"journal-article","created":{"date-parts":[[2012,9,11]],"date-time":"2012-09-11T01:11:12Z","timestamp":1347325872000},"page":"97-102","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["Fiber-optic intra-aortic balloon therapy and its role within cardiac surgery"],"prefix":"10.1177","volume":"28","author":[{"given":"G","family":"Yarham","sequence":"first","affiliation":[{"name":"Department of Clinical Perfusion Science, Essex Cardiothoracic Centre, Basildon, Essex, UK"},{"name":"Honorary Member, Department of Clinical Perfusion Research, Imperial College Health Science Centre, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A","family":"Clements","sequence":"additional","affiliation":[{"name":"Department of Clinical Perfusion Science, Essex Cardiothoracic Centre, Basildon, Essex, UK"},{"name":"Honorary Member, Department of Clinical Perfusion Research, Imperial College Health Science Centre, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C","family":"Morris","sequence":"additional","affiliation":[{"name":"Department of Clinical Perfusion Science, Essex Cardiothoracic Centre, Basildon, Essex, UK"},{"name":"Honorary Member, Department of Clinical Perfusion Research, Imperial College Health Science Centre, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T","family":"Cumberland","sequence":"additional","affiliation":[{"name":"Department of Clinical Perfusion Science, Essex Cardiothoracic Centre, Basildon, Essex, UK"},{"name":"Honorary Member, Department of Clinical Perfusion Research, Imperial College Health Science Centre, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M","family":"Bryan","sequence":"additional","affiliation":[{"name":"Department of Clinical Perfusion Science, Essex Cardiothoracic Centre, Basildon, Essex, UK"},{"name":"Honorary Member, Department of Clinical Perfusion Research, Imperial College Health Science Centre, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M","family":"Oliver","sequence":"additional","affiliation":[{"name":"Department of Clinical Perfusion Science, Essex Cardiothoracic Centre, Basildon, Essex, UK"},{"name":"Honorary Member, Department of Clinical Perfusion Research, Imperial College Health Science Centre, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H","family":"Burrows","sequence":"additional","affiliation":[{"name":"Department of Clinical Perfusion Science, Essex Cardiothoracic Centre, Basildon, Essex, UK"},{"name":"Honorary Member, Department of Clinical Perfusion Research, Imperial College Health Science Centre, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J","family":"Mulholland","sequence":"additional","affiliation":[{"name":"Department of Clinical Perfusion Science, Essex Cardiothoracic Centre, Basildon, Essex, UK"},{"name":"Honorary Member, Department of Clinical Perfusion Research, Imperial College Health Science Centre, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2012,9,10]]},"reference":[{"key":"bibr1-0267659112454156","first-page":"461","volume":"43","author":"Kirksey L","year":"2002","journal-title":"J Cardiovasc Surg"},{"key":"bibr2-0267659112454156","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-0704(18)30227-6"},{"key":"bibr3-0267659112454156","first-page":"177","volume-title":"Hemodynamic monitoring: invasive and non-invasive clinical application","author":"Darovic G","year":"1995"},{"key":"bibr4-0267659112454156","unstructured":"Daily E, Schroeder J.
