Abstract
saturation improved with V-A ECLS, and subsequently, remaining unchanged with either Impella or PA cannula as unloading strategy (SVmO2: Impella 86.0 ± 5.8 vs 87.8 ± 5.8; PA cannula 82.5 ± 10.7 vs 82.5 ± 11.3 %). Transaortic suction and PA drainage provided effective LV unloading during V-A ECLS while maintaining adequate end-organ perfusion. Impella provides a greater LV unloading effect and reduces more effectively the total LV stroke work.
