Key Points
Continuous-flow left ventricular assist systems are new-generation devices with a number of major advantages over previous pulsatile technology:
- •
Continuous-flow, rotary blood pumps eliminate the need for a blood pumping chamber and volume compensation.
- •
A lighter, smaller pump is better suited for patients with a smaller body size.
- •
Simple designs include only 1 internal moving part, the rotor, and no internal valves. This affords markedly enhanced device durability.
- •
They are silent in
