Versatility of Impella® Ventricular Assist Devices in High-risk Cardiac Patients During Complex Procedures: A Case Series.

High-risk cardiac patients undergoing complex electrophysiology procedures face potential hemodynamic instability, necessitating effective mechanical circulatory support. The catheter-based Impella^® ventricular assist device (Abiomed, Danvers, MA, USA) is crucial to stabilizing hemodynamics by improving the flow of blood from the left ventricle to the aorta. Its automated controller ensures cerebral hemodynamic stability, allowing for bedside adjustments. Herein, we present a case series illustrating the versatility of the Impella^® device in managing patients during complex electrophysiology procedures and highlighting its role in mitigating hemodynamic compromise.
