The Role of Impella for Hemodynamic Support in Patients With Aortic Stenosis

The goal of this review is to discuss the effects of Impella (Abiomed, Danvers, MA), to support in the hemodynamics of patients with severe aortic stenosis, and to explore the clinical scenarios in which the use of Impella may be beneficial in this setting.

The management of patients with severe aortic stenosis who go on to develop left ventricular failure and cardiogenic shock remains an important clinical challenge associated with increased morbidity and mortality. Once considered a relative contraindication, the use of Impella in severe aortic stenosis has now been proven feasible and demonstrated promising results in selected high-risk patients. The use of Impella to provide hemodynamic support maybe considered in patients with aortic stenosis in cardiogenic shock or those with severe left ventricular dysfunction and CAD who require high-risk PCI and or balloon aortic valvuloplasty. Impella is also an attractive option in selected cases of hemodynamic collapse during TAVR.
