Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the trial is to identify factors which can be used as guidance when optimizing continuous-flow left ventricular assist device (CF-LVAD) settings.

The hypothesis of the study is that pulmonary capillary wedge pressure (PCWP) will change independently of left ventricular end diastolic diameter (LVEDD) when increasing pump speed ie ΔPCWP/RPM ≠ ΔLVEDD/RPM.

The primary combined endpoint of the study is correlation between ΔPCWP and LVEDD slope under ramp testing in a cohort of "continuous-flow left ventricular assist device" heart failure patients.
