Triage VADs: TandemHeart, Impella, and CentriMag

  • Igor D. Gregoric


Considerable progress has been made in recent years for the treatment of acute heart failure. The first goal of therapy for cardiogenic shock is to restore circulation to avoid development of multiple organ failure, which may be accomplished with mechanical circulatory support devices that are designed for rapid implantation and short-term use. The intra-aortic balloon pump is the mainstay device for rapid support, but recently developed systems can provide higher levels of support. The TandemHeart (CardiacAssist Inc., Pittsburgh, PA) and the Impella (ABIOMED Inc., Danvers, MA) are percutaneously inserted for left ventricular assist. The inflow for the TandemHeart is via a transseptally placed cannula in the right atrium, and outflow is in the femoral artery. The Impella is inserted through a peripheral artery and is passed retrograde into the left ventricle. During support with the Impella blood is pumped from the left ventricle into the ascending aorta. The CentriMag ventricular assist device utilizes an extracorporeal blood pump and surgically implanted cannulas for univentricular or biventricular assist. These versatile devices can be applied in various hospital settings and may be applied in a broad population of heart failure patients. Continued clinical research will better define clinical applications for these devices.
