Figure 2. Components of contemporary left ventricular assist devices.

Figure 2

This figure summarizes key internal and external components of contemporary left ventricular assist devices. (1) Blood flows from the left ventricle to the inflow cannula (not shown but inserted into the left ventricular apex) through the pump and into the outflow graft to the aorta; (2) the driveline extends from the pump and out through the abdominal wall to the (3) external controller; (4) the main energy source for the pump is external batteries or an AC power source (not shown). AC indicates alternating Current;  CV‐LVADs, continuous flow left ventricular assist device; HMII, HeartMate II; HM3, HeartMate 3; and rpm, rotations per minute.
