Is the Impella 2.5 system feasible and safe for hemodynamic support during high-risk percutaneous interventions in patients with severe aortic stenosis and left ventricular dysfunction?
Continuous flow LV assist with Impella 2.5 is technically feasible and can provide periprocedural hemodynamic support in high-risk patients with severe aortic stenosis undergoing interventions.
Martinez et al. (2012) conducted an observational in symptomatic aortic stenosis (n=21). Impella 2.5 system was evaluated on 30-day mortality. Continuous flow left ventricular assist with Impella 2.5 during high-risk percutaneous procedures in patients with severe aortic stenosis resulted in a 30-day mortality of 14.2%.
