A persistent LV thrombus poses risks of pump thrombosis and stroke in LVAD recipients. The relationship between pre-operative echocardiography and intraoperative findings at LVAD implantation has not previously been studied.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A retrospective review examined all patients undergoing LVAD placement or exchange from October 2011 to March 2014. Pre-Operative TTE and TEE data were validated with presence of LV thrombus during the direct inspection at the time of LVAD placement, and the findings were analyzed quantitatively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Between October 2011 and March 2014, 99 patients underwent a total of 107 LVAD implants. Pre-Operative TTE was available in 93 (86.9%) cases, while pre-operative TEE was available in 37 cases (34.6%). On pre-operative TTE, LV thrombus was correctly identified in only two cases, while on pre-operative TEE no cases of LV thrombus were identified correctly, and there were 2 false positive reports. Intraoperative inspection revealed presence of LV thrombus in 14 cases. The sensitivity of pre-operative TTE was 16.7% and the specificity 100% in detecting LVT, compared to 0% and 93.8%, respectively, for TEE.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Pre-Operative echocardiogram offers low accuracy for presence of LV thrombus. Overall, the sensitivity is too low to reliably exclude thrombus. This could have significant implications in planning off-pump LVAD exchange as thrombus could be missed. More data are necessary to determine whether this could have significant effects on thromboembolic complications and survival.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.5301\/ijao.5000526","type":"journal-article","created":{"date-parts":[[2016,11,4]],"date-time":"2016-11-04T07:38:49Z","timestamp":1478245129000},"page":"487-490","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["Echocardiographic Detection of Left Ventricular Thrombus in Patients Undergoing Heartmate II Left Ventricular Assist Device Implantation"],"prefix":"10.1177","volume":"39","author":[{"given":"Heidi B.","family":"Schubmehl","sequence":"first","affiliation":[{"name":"Division of Cardiothoracic Surgery, University of Rochester Medical Center, Rochester, New York - USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vakhtang","family":"Tchantchaleishvili","sequence":"additional","affiliation":[{"name":"Division of Cardiothoracic Surgery, University of Rochester Medical Center, Rochester, New York - USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eugene","family":"Storoznsky","sequence":"additional","affiliation":[{"name":"Division of Cardiology, University of Rochester Medical Center, Rochester, New York - USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeffrey D.","family":"Alexis","sequence":"additional","affiliation":[{"name":"Division of Cardiology, University of Rochester Medical Center, Rochester, New York - USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leway","family":"Chen","sequence":"additional","affiliation":[{"name":"Division of Cardiology, University of Rochester Medical Center, Rochester, New York - USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Howard T.","family":"Massey","sequence":"additional","affiliation":[{"name":"Division of Cardiothoracic Surgery, University of Rochester Medical Center, Rochester, New York - USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2016,3,11]]},"reference":[{"key":"bibr1-ijao.5000526","doi-asserted-by":"publisher","DOI":"10.1016\/S1388-9842(00)00126-4"},{"key":"bibr2-ijao.5000526","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjcard.2013.12.015"},{"key":"bibr3-ijao.5000526","doi-asserted-by":"publisher","DOI":"10.1097\/00019501-200508000-00003"},{"key":"bibr4-ijao.5000526","first-page":"110","author":"Antman E.
