Fig 1 The pump is exposed through a left subcostal incision. A self-retaining Rultract retractor (Rultract Inc, Inc, Cleveland, OH) is used to provide adequate exposure to the HeartMate II (St. Jude Medical, Inc, St. Paul, MN) left ventricular assist device, inflow, and outflow.

Fig 2 Subcostal tissue and ribs are retracted with a Rultract retractor (Rultract Inc, Inc, Cleveland, OH). The new HeartMate II (St. Jude Medical, Inc, St. Paul, MN) left ventricular assist device is in the forefront, and a vascular clamp is on the outflow cannula of the old HeartMate II pump.

Fig 3 The old HeartMate II (St. Jude Medical, Inc, St. Paul, MN) left ventricular assist device is removed. A vascular clamp on the outflow cannula and the surgeon’s thumb on the inflow cannula achieve hemostasis.
