Right Heart Failure Management: Focus on Mechanical Support Options.

Millions of American adults suffer from right heart failure (RHF), a condition associated with high rates of hospitalization, organ failure, and death. There is a multitude of etiologies and mechanisms that lead to RHF, often in a feedforward spiral of decline. The management of advanced cases of RHF can be particularly difficult. For patients who are refractory to the medical optimization of volume status, hemodynamic and pharmacologic support, and rhythm control, mechanical therapies may be warranted. Currently available mechanical assist devices for RHF include venoarterial extracorporeal oxygenation and right ventricular assist devices, both surgical and percutaneous. Each advanced therapy has its own potential advantages and limitations, and often is appropriate in different clinical contexts. In this review, the authors describe the pathophysiology and medical therapies for RHF and then focus on the different types of advanced therapies that currently exist to help inform medical decision-making for this complicated patient cohort.
