Percutaneous Mechanical Support for the Failing Right Heart

Right ventricular (RV) failure is an increasingly common clinical problem that may require mechanical support. In contrast to severe left ventricular failure, RV failure is typically more reversible. Therefore, application of shorter-term percutaneous support devices is potentially attractive. Current innovations promise greater availability of such percutaneous RV support devices. This article considers the available mechanical approaches to provide hemodynamic support to treat profound RV failure in the common clinical scenarios in which percutaneous mechanical RV support may be most beneficial.
