Emerging Modalities for Temporary Mechanical Circulatory Support in Cardiogenic Shock.

Abstract

Cardiogenic shock (CS) is a life-threatening medical condition that requires prompt recognition and treatment. The use of standardized CS criteria, such as the Society for Cardiovascular Angiography and Interventions criteria, can categorize patients and guide therapeutic strategies. Temporary mechanical circulatory support (MCS) devices have become valuable tools in the treatment of CS, as they can provide cardiovascular support as a bridge to recovery, cardiac surgery, or advanced therapies such as cardiac transplant or durable ventricular assist devices. The use of MCS should be tailored to each individual patient, focused on a stepwise escalation of circulatory support to support both end-organ perfusion and myocardial recovery. As newer MCS devices reduce myocardial oxygen demand without increasing ischemia, the possibility of recovery is optimized. In this review, we discuss the different modalities of MCS focusing on the mechanism of support and the advantages and disadvantages of each device.
