Key result
A new percutaneous intra-aortic axial flow pump demonstrated a positive relationship between rotational speed and generated pressure, and between propeller diameter and pressure in bench testing.
Why the study?

Bench-tested hydraulics support device optimization for LV support; leaves open in vivo efficacy and clinical translation.
Reitan et al. (2000) studied Left ventricular heart failure. Percutaneous intra-aortic axial flow pump with a foldable propeller was evaluated on Pressure generation and flow-pressure characteristics. A new percutaneous intra-aortic axial flow pump demonstrated a positive relationship between rotational speed and generated pressure, and between propeller diameter and pressure in bench testing.
