Non-pulsatile circulation with axial-flow left ventricular assist device preserves neurocognitive function.
Concerns about the potential impact of the non-pulsatile circulation pattern generated by the new generation axial-flow left ventricular assist devices on neurocognitive function led us to evaluate a patient in whom a Jarvik 2000 pump was implanted. We assessed the patient's baseline neurocognitive function preoperatively as well as at 1-month and 6-month follow-up, using a comprehensive battery of neuropsychological tests. A slight improvement in circumscribed neurocognitive domains was noted, with no evidence of further decline at the end of a 6-month follow-up period.
