N2 - Aims The ELEVATE registry was planned to study post-approval outcomes with HeartMate 3™ (HM3), a fully magnetically levitated continuous flow left ventricular assist device (LVAD). Methods and results A total of 482 patients provided consent to participate in ELEVATE (enrolled cohort). Data collection included baseline demographics, survival, adverse events, quality of life (QOL) [EuroQoL-5 Dimensions visual analogue scale (VAS), and 6-minute walk distance (6MWD)]. An additional 58 patients were implanted with HM3 during the same period but expired or were explanted prior to consent, and only survival data were collected (anonymized cohort). We report the 6-month outcomes of the patients who received HM3 as their primary implant (n = 463) and the survival of the 540 patients in the full cohort (enrolled + anonymized). Baseline characteristics included a mean age of 55.6 ± 11.7 years, 89% male, 48% ischaemic aetiology, and 70% on inotropes. The majority of patients (66%) were bridge-to-transplantation (BTT) and 32% were INTERMACS profile 1-2. Full cohort survival at 6 months was 82 ± 2%. In the enrolled primary implant patients, there was no incidence of pump thrombosis, major bleeding was 25%, major infection 35%, and any stroke type 5%. Functional capacity improved significantly (6MWD 230 ± 191 m) as did QOL (VAS 31 ± 23). Freedom from unplanned rehospitalizations at 6 months was 68 ± 2%. Conclusion The 6-month outcomes of the HM3 LVAD demonstrate a highly reliable, thrombosis free, device with low incidence of stroke and improved functional capacity, and QOL. ClinicalTrials. gov Identifier NCT02497950.
