**Abstract**

Meaningful and contemporary data regarding the clinical use of mechanical circulatory support (MCS) is founded on the work conducted in the 1950s when a "heart-lung" machine was incorporated to provide support during surgical interventions. Following this milestone, the need to support artificial circulation in patients with heart failure initiated an investigational and legislative collaboration to implement the mission-oriented Artificial Heart Program in the United States during the 1960s. In the subsequent decades, technological discoveries have integrated a series of mechanical systems employed as therapeutic options for short- and long-term artificial circulation in children and adults with advanced heart failure. Since their clinical application, MCS devices have been employed as a bridge to transplantation in over 4000 patients globally. In recent years, the adverse effects and economic burden of MCS have been counterbalanced by the harmonization of therapeutic protocols, the inclusion of multidisciplinary insight, and the allowance of families and patients to participate in shared decision making to address candidacy. In this chapter, we provide a review of the historical aspects of MCS, a therapeutic option for overcoming complexities encountered in reestablishing adequate hemodynamic states and providing a reasonable quality of life.
