Impella RP in the Treatment of Right Ventricular Failure: What We Know and Where We Go

Temporary mechanical circulatory support devices for the treatment of acute right ventricular failure represent crucial tools for clinical practice. Right ventricular failure presents specific treatment issues, and dedicated percutaneous devices are less in number compared to the left ventricle. Current data and insights on mechanical circulatory support for the right ventricle come mostly from the context of cardiac surgery, predominantly the setting of acute right ventricular failure after left ventricular assist device implantation.The Impella RP (Abiomed, Danvers, MA) is a minimally invasive temporary device that has gained application for the percutaneous treatment of right ventricular failure with positive clinical results. Even though treatment indications are clear, technical and management issues still are relevant because of the limited scientific data available. Appropriate positioning and repositioning, interaction with right ventricular valvular apparatus, anticoagulation management, weaning, and patient mobilization are examples of the open challenges. In line with the positive initial experience with this device, future research efforts should be focused on the improvement of device limitations and on providing additional data that might drive optimal clinical management.
