Abstract: Cardiogenic Shock (CS) is a major challenge in current cardiology. Over the last decade, cardiogenic shock mortality has decreased somewhat, but it still remains high, particularly when associated with ischaemic heart disease. The challenges are numerous and include prevention, accurate diagnosis, prompt management and effective therapies to support a failing heart and prevent multi-organ failure. Despite improvements in the care of Acute Coronary Syndrome (ACS), it remains the most common cause of CS. In addition to existing medical therapy, mechanical circulatory support has been proposed for the management of ventricular failure. The intra-aortic balloon pump was amongst the first widely used percutaneous mechanical support devices, and more recently, systems providing a higher level of support have been developed. Although the evidence supporting their use is limited, they have the potential to significantly reduce CS-associated mortality. In this narrative review, we summarize the available evidence and discuss the future directions regarding percutaneous mechanical circulatory support in patients with left ventricular dysfunction and CS complicating ACS.
