Introduction:
Left ventricular assist devices have been demonstrated to improve both quality of life and improve survival in patients with end-stage heart failure. Ideal speed setting of these devices is necessary to provide adequate left ventricular unloading while not disadvantaging the right heart. This highlights the potential utility of speed titration studies.
Methods:
PubMed, Scopus, and the Cumulative Index to Nursing and Allied Health Literature databases were searched for: (LVAD) OR (Left Ventricular Assist Device) OR (VAD) OR (Ventricular Assist Device) AND (Speed Optimization) OR (Ramp Study) from inception to April 2025.
Results:
22 studies with 749 total patients were included, 45% of whom had a Heart Mate 3. Outcomes of interest included mortality, readmission, RV function, speed change at conclusion of the study, and quality of life. Only 1 out of 22 studies reported all 5 outcomes, with 64% reporting 2 or fewer outcomes of interest.
Conclusion:
There exists limited data on speed optimization in the HM3, and that which has been reported lacks a standardization regarding method of evaluation as well as outcomes reporting. Prospective studies, with a standard method of speed optimization and more detailed outcomes reporting, are necessary in order to define best practices.
