Simultaneous Multi-Vascular Bed Imaging in a Patient Supported by a Continuous-Flow LVAD

Patients supported with left ventricular assist devices (LVADs) are burdened by frequent hemocompatibility-related adverse events related to patient-pump interactions. These predominantly vascular events include stroke, gastrointestinal bleeding, and pump thrombosis. Our center performs routine, invasive hemodynamic ramp speed titrations in LVAD patients to determine the optimal rotational speed after implantation. We sought to interrogate changes in vascular hemodynamics during an exercise ramp study to understand the influence of pump speed and exercise on outflow graft and cerebrovascular flow.
