In the perioperative setting, interrogating the HeartWare devices is very difficult due to the interference of the Doppler by the impeller frequency and generation of the waterfall artifact. We present a case where using color Doppler a view \u201cinside\u201c the impeller can be seen which corresponds to the centrifugal flow of blood. With time, these images can be looked into in pathological states such as pump thrombosis, to come to a more meaningful conclusion regarding the flow of blood within the centrifugal chamber. Newer technologies are constantly evolving to give us more meaningful insights into the flow of blood within the heart chambers. We believe similar technologies can be applied to see the flow of blood inside the LVAD devices.<\/jats:p>","DOI":"10.4103\/aca.aca_149_17","type":"journal-article","created":{"date-parts":[[2024,5,28]],"date-time":"2024-05-28T06:37:25Z","timestamp":1716878245000},"page":"92-94","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":3,"title":["Looking Inside the Third Generation Left Ventricular Assist Device Using Color Doppler Transesophageal Echocardiography"],"prefix":"10.4103","volume":"21","author":[{"given":"Ankit","family":"Jain","sequence":"first","affiliation":[{"name":"Department of Anesthesiology, Augusta University and Medical College of Georgia, Augusta, GA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frederick C","family":"Cobey","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Tufts Medical Center, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-20250602","doi-asserted-by":"crossref","first-page":"1208","DOI":"10.1213\/ANE.0000000000000664","article-title":"Echocardiographic artifact induced by heartware left ventricular assist device","volume":"120","author":"Lesicka","year":"2015","journal-title":"Anesth Analg"},{"key":"R2-20250602","doi-asserted-by":"crossref","first-page":"497","DOI":"10.1053\/j.jvca.2016.11.038","article-title":"Left ventricular assist device thrombosis is associated with an increase in the systolic-to-diastolic velocity ratio measured at the inflow and outflow cannulae","volume":"31","author":"Jain","year":"2017","journal-title":"J Cardiothorac Vasc Anesth"},{"key":"R3-20250602","doi-asserted-by":"crossref","first-page":"362","DOI":"10.1093\/ejechocard\/jer265","article-title":"Transoesophageal echocardiographic Doppler colour flow patterns of a normally functioning third-generation centrifugal left ventricular assist device","volume":"13","author":"Najib","year":"2012","journal-title":"Eur Heart J Cardiovasc Imaging"},{"key":"R4-20250602","doi-asserted-by":"crossref","first-page":"305","DOI":"10.1016\/j.jcmg.2012.01.003","article-title":"Emerging trends in CV flow visualization","volume":"5","author":"Sengupta","year":"2012","journal-title":"JACC Cardiovasc Imaging"},{"key":"R5-20250602","doi-asserted-by":"crossref","first-page":"899","DOI":"10.1016\/j.jacc.2006.07.075","article-title":"Left ventricular isovolumic flow sequence during sinus and paced rhythms: New insights from use of high-resolution Doppler and ultrasonic digital particle imaging velocimetry","volume":"49","author":"Sengupta","year":"2007","journal-title":"J Am Coll Cardiol"},{"key":"R6-20250602","doi-asserted-by":"crossref","first-page":"1701","DOI":"10.1109\/TMI.2010.2049656","article-title":"Two-dimensional intraventricular flow mapping by digital processing conventional color-Doppler echocardiography images","volume":"29","author":"Garcia","year":"2010","journal-title":"IEEE Trans Med Imaging"},{"key":"R7-20250602","doi-asserted-by":"crossref","first-page":"2414","DOI":"10.1016\/j.ultrasmedbio.2016.06.009","article-title":"Intra-operative vector flow imaging using ultrasound of the ascending aorta among 40 patients with normal, stenotic and replaced aortic valves","volume":"42","author":"Hansen","year":"2016","journal-title":"Ultrasound Med Biol"}],"container-title":["Annals of Cardiac Anaesthesia"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/00660469-201821010-00024","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T13:16:21Z","timestamp":1787836581000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/00660469-201821010-00024"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,1]]},"references-count":7,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2018]]}},"URL":"https:\/\/doi.org\/10.4103\/aca.aca_149_17","relation":{},"ISSN":["0971-9784","0974-5181"],"issn-type":[{"value":"0971-9784","type":"print"},{"value":"0974-5181","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,1]]}}}
