1. A mechanical circulatory support system for a heart, the mechanical circulatory support system comprising:
a pump having a distal end and a proximal end, the pump comprising a rotor, the rotor having at least one blade;
a pump housing, the pump housing surrounding the at least one blade of the rotor; and
a catheter having a distal end, a proximal end, an inner surface, and an outer surface, the catheter extending proximally relative to the pump housing, the outer surface of the catheter configured to contact blood when disposed within patient vasculature; and
a cooling element configured to cool the blood that comes in contact with the outer surface of the catheter, wherein the cooling element is formed as a lumen that extends along a length of the catheter.
