Impella 5.5®: l’ultima innovazione nel campo dei sistemi di assistenza al ventricolo sinistro

The Impella 5.5® (Abiomed Inc., Danvers, MA, USA) is a temporary mechanical circulatory support device utilized for the management of cardiogenic shock. In this review, we outline the device's key features, paying particular attention to its indications and contraindications, the surgical technique for implantation, and potential complications. Additionally, we emphasize the potential benefits of using the Impella as a bridge to left ventricular assistance device implantation, a safe strategy to mitigate the risk of right heart failure.
