Severe right ventricular (RV) failure is a significant cause of morbidity and mortality, with an in-hospital mortality rate up to 70% to 75%. Medical management is employed and is successful for most of these patients. However, a small percentage of patients will continue to have persistent RV failure, for which mechanical support is used for management.
