Circulatory assist devices were initially designed to support patients in hemodynamic collapse, but are now used for a wide range of clinical conditions ranging from prophylactic insertion for invasive procedures to cardiogenic shock or cardiopulmonary arrest. There are three major types of percutaneous devices (as well as surgically-implanted ventricular assist devices):
●Counterpulsation devices (intraaortic balloon pump [IABP] and noninvasive counterpulsation) (image 1)
●Cardiopulmonary assist devices (Cardiopulmonary support or CPS)
●Left ventricular assist devices (eg, Impella) (image 2)
The IABP is the most commonly used mechanical support device. It has a long clinical record of success, is simple, is inserted easily and rapidly, is the least expensive of all the devices, and does not require constant monitoring by technical support personnel. (See "Intraaortic balloon pump counterpulsation".)
