Because most of these patients had surgeries at hospitals that were newly accredited, we sought to examine the impact of LVAD center volume on the outcomes of DT.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>Methods and Results\u2014<\/jats:italic>\n            <\/jats:bold>\n            From July 1998 through December 2005, a total of 377 patients underwent implantation of HeartMate I LVAD as DT at 68 centers in the United States. Using data from the Thoratec DT Registry, we examined the association between LVAD center volume at the time of surgery and 1-year survival with DT. Of the studied 377 DT recipients, 53% underwent device implantation at centers that performed \u22644 DT implants at the time of surgery. Center experience with DT seemed to significantly correlate with the 1-year survival (47.8% versus 67.4% in recipients of \u22644th DT versus &gt;9th DT implant;\n            <jats:italic>P<\/jats:italic>\n            =0.009). However, the DT center volume was not an independent predictor of 1-year survival with DT when adjusted for the preoperative DT Risk Score, suggesting that other factors, such as improved candidate selection, may have accounted for the institutional learning curve.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>Conclusions\u2014<\/jats:italic>\n            <\/jats:bold>\n            The institutional experience with DT may have a significant impact on outcomes of this therapy. Better selection of candidates, systemic approach to surgical and postoperative care, as well as the long-term medical management most likely all contribute to these improvements.\n          <\/jats:p>","DOI":"10.1161\/circheartfailure.108.796128","type":"journal-article","created":{"date-parts":[[2009,1,21]],"date-time":"2009-01-21T11:47:59Z","timestamp":1232538479000},"page":"3-10","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":63,"title":["Impact of Center Volume on Outcomes of Left Ventricular Assist Device Implantation as Destination Therapy"],"prefix":"10.1161","volume":"2","author":[{"given":"Katherine","family":"Lietz","sequence":"first","affiliation":[{"name":"From the Cardiovascular and Cardiothoracic Divisions of Columbia University Medical Center (K.L., M.D., Y.N., D.M.), New York, NY;
