Cardiac recovery from cardiogenic shock (CS) and end-stage chronic heart failure (HF) remains an often insurmountable therapeutic challenge. The counterpulsation technique exerts numerous beneficial effects on systemic hemodynamics and left ventricular mechanoenergetics, rendering it attractive for promoting myocardial recovery in both acute and chronic HF. Although a recent clinical trial has questioned the clinical effectiveness of short-term hemodynamic support with intra-aortic balloon pump (IABP, the main representative of the counterpulsation technique) in CS complicating myocardial infarction, the issue remains open to further investigation. Moreover, preliminary data suggest that long-term IABP support in patients with end-stage HF is safe and may mediate recovery of left- or/and right-sided cardiac function, facilitating long-term weaning from mechanical support or enabling the application of other permanent, life-saving solutions. The potential of long-term counterpulsation could possibly be enhanced by implementation of novel, fully implantable counterpulsation devices.
Core tip: The counterpulsation technique induces beneficial effects on systemic hemodynamics and left ventricular mechanoenergetics. In this manner, it may facilitate myocardial recovery in acute and chronic heart failure (HF). The intra-aortic balloon pump (IABP) remains the main representative of the counterpulsation technique. Although recent data have questioned the effectiveness of short-term hemodynamic support with IABP in cardiogenic shock complicating myocardial infarction, the issue remains open to further investigation. Preliminary data suggest that long-term IABP support in patients with end-stage HF is safe and may mediate recovery of left- or/and right-sided cardiac function. Novel, fully implantable counterpulsation devices, which enable long-term counterpulsation, are described in this manuscript.
