Arms Assigned Interventions
Experimental: IMPELLA LP 2.5 Device: Impella LP 2.5
Insertion of the LP 2.5 IMPELLA circulatory support system that can be placed across the aortic valve using a single femoral site. The device pumps blood from the left ventricle into the ascending aorta at 2.5L/min.
Active Comparator: Intra-Aortic Balloon Pump Device: Intra-Aortic Balloon Pump
The Intra-Aortic Balloon Pump consists of a cylindrical balloon that sits in the aorta and counterpulsates.
