title: Right ventricular assist devices and the surgical treatment of right ventricular failure.
abstract: Treatment of patients with severe right ventricular dysfunction follows a continuum of progressive therapies. If optimization of volume status and inotropic support do not adequately improve right ventricular function, higher levels of mechanical circulatory support are required. A right-sided intraaortic balloon pump has been helpful in such circumstances. The centrifugal pump and the artificial ventricle provide the most effective long-term circulatory support for patients with right ventricular or biventricular failure after cardiopulmonary bypass, myocardial infarctions, or as a bridge to cardiac transplantation. All of these support measures still carry a high morbidity and mortality. Survival in approximately one third of these high-risk patients can be expected with the use of right ventricular assist devices. Cardiopulmonary bypass has also been effective for circulatory support of patients with massive pulmonary emboli.
