BACKGROUND: In heart failure (HF) patients with renal insufficiency (RI), we hypothesize that mechanical circulatory support (MCS) with the left ventricular assist device (LVAD) will promote renal function recovery (RR). We sought to quantify RR with LVAD support over 6 months of follow-up.
METHODS: RR data at 30, 90, and 180 days were analyzed for all LVAD patients with RI at the time of surgery. RI was defined as either the use of hemodialysis (HD) or a glomerular filtration rate (GFR) less than 60 mL/min/1.73 m2 .
RESULTS: Between January 2008 and December 2013, 47 of 127 (37%) LVAD recipients had RI at the time of surgery. The mean preoperative GFR was 48 ± 7. We observed RR at each follow-up, with 30-, 90-, and 180-day mean GFRs of 79 ± 33, 71 ± 31, and 63 ± 21, respectively. The absolute increase in GFR at 30, 90, and 180 days was 34 ± 31, 26 ± 29, and 19 ± 20, respectively (All with P < .001). Four patients (8.5%) with RI required HD preoperatively. Of these, three recovered renal function, the fourth patient died. An additional 13 patients (30.2%) that were previously non-HD-dependent required HD postoperatively. Six of these 13 (46%) recovered renal function during the study period, four (30.7%) remain on HD and three (23%) died.
CONCLUSIONS: RI improves significantly with LVAD support. Improvements in GFR are marked in the first 30 days. Among those patients requiring either pre- or post-operative HD, a majority recovered renal function.
