Risk factors for RVAD implantation and the combined end point of RVAD or death within 14 days of LVAD were assessed with stepwise logistic regression. We compared survival between patients with and without RVAD using Kaplan\u2013Meier method and Cox proportional hazards modeling. Of 9976 patients undergoing continuous-flow\u2013LVAD implantation, 386 patients (3.9%) required an RVAD within 14 days of LVAD surgery. Preimplant characteristics associated with RVAD use included interagency registry for mechanically assisted circulatory support patient profiles 1 and 2, the need for preoperative extracorporeal membrane oxygenation or renal replacement therapy, severe preimplant tricuspid regurgitation, history of cardiac surgery, and concomitant procedures other than tricuspid valve repair at the time of LVAD. Hemodynamic determinants included elevated right atrial pressure, reduced pulmonary artery pulse pressure, and reduced stroke volume. The final model demonstrated good performance for both RVAD implant (area under the curve, 0.78) and the combined end point of RVAD or death within 14 days (area under the curve, 0.73). Compared with patients receiving an isolated LVAD, patients requiring RVAD had decreased 1- and 6-month survival: 78.1% versus 95.8% and 63.6% versus 87.9%, respectively (\n              <jats:italic>P<\/jats:italic>\n              &lt;0.0001 for both).\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions:<\/jats:title>\n            <jats:p>The need for RVAD implantation after LVAD is associated with indices of global illness severity, markers of end-organ dysfunction, and profiles of hemodynamic instability.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/circheartfailure.117.003863","type":"journal-article","created":{"date-parts":[[2017,10,12]],"date-time":"2017-10-12T00:10:17Z","timestamp":1507767017000},"update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":103,"title":["Early Right Ventricular Assist Device Use in Patients Undergoing Continuous-Flow Left Ventricular Assist Device Implantation"],"prefix":"10.1161","volume":"10","author":[{"given":"Michael S.","family":"Kiernan","sequence":"first","affiliation":[{"name":"From the Cardiovascular Center, Tufts Medical Center, Boston, MA (M.S.K., N.K.K., D.D.); Cardiovascular Institute, Beth Israel Deaconess Medical Center, Boston, MA (E.W.G.); Heart and Vascular Institute, Vanderbilt University Medical Center, Nashville, TN (M.B.); Division of Cardiothoracic Surgery, Northwestern Memorial Hospital, Chicago, IL (D.T.P.); Clinical and Translational Science Institute, Tufts University, Boston, MA (R.R.); Heart and Vascular Institute, University of Pennsylvania,..."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.
