Two cannulation approaches are shown in the figures below.
In both approaches, blood is returned via the ascending aorta. Left ventricular cannulation may be preferred because the unloading is
more complete, the risk of intra-ventricular thrombus is much lower, and collapse of the chamber is less likely, though care should be
taken to minimize the risk of suction.

5 The CentriMag Return (Arterial) Cannula and the CentriMag Drainage (Venous) Cannula are not intended for peripheral cannulation.
