Abstract

The Impella Recover 100 (Impella CardioSystems AG, Aachen, Germany) is an intravascular microaxial blood pump intended to provide short-term mechanical support for acutely reduced left ventricular function in the setting of postcardiotomy heart failure refractory to high-dose inotropic support and intra-aortic balloon pump support. The lowcost device is fast to insert across the aortic valve through a 10-mm vascular graft sewn to the ascending aorta, avoiding the use of cardiopulmonary bypass, is simple to remove, and is associated with good properties for weaning. However, the Impella has just recently been introduced into clinical practice, and no information is available about its use in patients who have previously undergone biologic aortic valve replacement, especially with small prosthesis sizes. This report summarizes our initial clinical experience with such a patient. It should encourage the surgical community to take the device into consideration for borderline indications as a last resort.
