From medical therapy to mechanical support: strategies for device selection and implantation techniques

Abstract

Abstract Cardiogenic shock (CS) is a complex clinical syndrome with a high risk of mortality. The recent, rapid development of temporary mechanical circulatory support (tMCS) has altered CS treatment. While catecholamines remain the cornerstone of CS therapy, tMCS usage has increased. According to shock severity, different treatment strategies including catecholamines alone, catecholamines and tMCS, or multiple tMCS might be used. State-of-the-art implantation techniques are necessary to avoid complications linked to the invasive nature of tMCS. In particular, bleeding and access-site complications might counteract the potential haemodynamic benefit of a percutaneous ventricular assist device. In this review, we describe the role of catecholamines in CS treatment and present the different tMCS devices with an explanation on how to use them according to CS aetiology and severity. Finally, an overview of the best practice for device implantation is provided.
