What is (1076) Longitudinal Analysis of Pump Settings Over Long-Term Support with the Heartmate3 Left Ventricular Assist Device about?

Purpose To analyze changes in pump settings over long-term support with the HeartMate3 left ventricular assist device (LVAD). Methods Values of pump speed, flow and pulsatility index were prospectively recorded in consecutive patients implanted with the HeartMate3. Data were recorded at the first follow-up following cardiac rehabilitation (baseline, t0) and then at t1=6, t2=12, t3=24, t4=36, t5=48 and t6=60 months of support. Demographic and pre-implant patient characteristics and hemodynamic and echocardiographic parameters at follow-up were also recorded. Results Data of 40 patients were analyzed. Pump speed and circulatory support were increased significantly over time for recurrence of symptoms of heart failure. Specifically, pump speed and flow were increased by +4% and +8% at t6 vs. baseline, respectively (pump speed: 5400 [5225-5750] rpm vs. 5250 [5200-5300] rpm, p=0.004; pump flow: 4.5 [4.0-5.2] L/min vs. 4.2 [3.4 4.5] L/min, p=0.03). Consistent with progressive increase in pump speed, significant decrease of the pulsatility index was also recorded (-28% at t6 vs. baseline; p=0.02). Echocardiographic assessment suggests that changes in pump settings promoted adequate LV unl
