The v-a ECLS is an effective approach for mechanical circulatory support, however, it is associated with several disadvantages. An increased afterload generated by a pump outflow leads to a left ventricular (LV) distension, pulmonary congestion, and lung edema on one hand and impairs myocardial perfusion on the other. In this chapter, we will discuss the rationality as well as different techniques for LV unloading during v-a ECLS support.
