An extracorporeal support system including an extracorporeal support apparatus and an arterial circulation support catheter. The arterial circulation support catheter includes a blood lumen with a proximal end coupled to extracoporeal support apparatus and a distal end inserted into the blood circulation. A vent lumen has a distal end that crosses the aortic valve into the left ventricle and provides direct venting of the left ventricle through the vent lumen. An arterial circulation support catheter occluding member is positioned either in an interior or at an exterior of the arterial circulation support catheter. A venous circulation support catheter is provided and includes a blood lumen with a proximal end coupled to the extracorporeal support apparatus and a distal end inserted into the blood circulation. A venous circulation support catheter occluding member is included and positioned in an interior or at an exterior of the venous circulation support catheter.
