Outcomes on Continuous Flow Left Ventricular Assist Devices: A Single Institutional 9-Year Experience (original) (raw)

2016, The Annals of thoracic surgery

Continuous-flow left ventricular assist devices (LVADs) have become the standard of care for patients with advanced heart failure. The goal of this study was to review our 9-year institutional experience. From March 2006 through May 2015, 231 patients underwent implantation of 240 CF LVADs, HeartMate II LVAD (Thoratec Corp., Pleasanton, CA; n = 205) or HVAD (HeartWare Inc., Framingham, MA; n = 35). Of these, 127 devices (52.9%) were implanted as bridge to transplantation (BTT) and 113 (47.1%) as destination therapy (DT). Mean age was 51.2 ± 11.9 years for BTT patients and 58.2 ± 11.4 years for DT patients (p < 0.001). There was a higher incidence of preoperative diabetes, renal insufficiency, peripheral vascular disease, and previous cardiac operation in DT patients (p < 0.05). Survival was higher for BTT patients, with 1-, 6-, 12-, and 24-month survivals of 91.0%, 90.0%, 88.5%, and 72.1%, respectively, versus 85.3%, 81.1%, 75.6%, and 59.0%, respectively, for DT patients (p = ...
