Pump flow setting and assessment of unloading in clinical practice.

Eur Heart J Suppl 2021 Mar 27;23(Suppl A):A23-A26. Epub 2021 Mar 27.

Department of Anesthesia and Intensive Care, IRCCS ISMETT, UPMC Italy, Via Ernesto Tricomi, 5, 90127 Palermo, Italy.

The rationale for mechanical circulatory support (MCS) in cardiogenic shock is to restore cardiac output in selected patients when critically low or in case of refractory cardiac arrest. Furthermore, an MCS device that moves blood from either the left atrium or the left ventricle to the systemic circulation will potentially unload the ventricle. These devices are used alone or in combination with venoarterial extracorporeal membrane oxygenation (VA-ECMO). Read More
