Temporary mechanical cardiac support (TMCS) devices intend to restore systemic perfusion and prevent further end-organ damage in patients with refractory cardiogenic shock until the insult is addressed. TMCS has been associated with reductions in hospital costs and in-hospital mortality. We review the four primary TMCS modalities available: intra-aortic balloon pump, TandemHeart, veno-arterial extracorporeal membrane oxygenation, and Impella pump. All have their own implantation technique and hemodynamic profile, and their use may therefore be tailored to the specific patient's needs. The appropriate TMCS may thus help stabilize the patient, enabling the care team to make decisions about durable support or transplantation.
