Implantation of Short-Term and Long-Term Right Ventricular Assist Devices

The last decade has seen considerable growth in the use of left ventricular assist devices (LVAD), in end-phase heart failure treatment. The indications, contraindications and implantation techniques are well-defined. However, information about mechanical support for right ventricular failure is lacking. The aim of this communication is to present alternative techniques for implantation of short- and longterm right ventricular assist devices. Implanting the device in the right atrium has certain advantages when compared with the right ventricle. It is an easier surgical technique that preserves the tricuspid valve and it can potentially reduce the risk of pump thrombosis.
