  • Patients with left ventricular assist devices (LVADs) who require intermittent hemodialysis (iHD) are considered to have a poor prognosis despite a paucity of supportive evidence, mostly from small single-center cohorts and extrapolations from studies of patients who received continuous renal replacement therapy but no iHD. We conducted a systematic review and individual-participant-data meta-analysis of the literature including our single-center cohort to examine the outcomes of patients initiated on iHD following LVAD implantation. Sixty-four patients from 5 cohorts met selection criteria (age 57.5 [46-64.5] years, 87% HeartMate II, mostly bridge to transplantation). Follow-up after iHD initiation was 87.5 (38.5-269.5) days, although it was considerably longer in our center than in other cohorts (601.5 [93-1559] days vs 65 [26-180] days, P = 0.0007). The estimated median survival was 308 (76-912.5) days and varied significantly among cohorts, ranging from 60 (57-65) to 838 (103-1872) days (P = 0.0096). Twelve (18.8%) patients achieved either heart transplantation (HT) or remission during follow-up. Patients who received HT had an 8-fold longer estimated median survival (1972 [799-1972] days vs 244 [64-838] days, P = 0.0112). Being from a more recent cohort was associated with better 1-year survival. Renal recovery occurred in eight patients (13.1%) at 30 days and its cumulative incidence increased to 73% (27/37 patients with available data) at 1 year. Most patients initiated on iHD after LVAD experienced renal recovery within the first year after implantation. Improved survival was observed for patients who received HT and in those from more recent cohorts. Some patients were able to survive on LVAD and iHD support for several years.
