Comprehensive evaluation of Impella RP® in right ventricular failure.

Right ventricular failure is a severe medical condition characterized by a sudden or a progressive reduction of the function of the right heart. This condition, if left untretated, leads to low blood pressure, reduced oxygen supply to other organs as brain, liver and kidneys, and eventually death. The right ventricular failure can be the consequence of a heart attack or a progressive disease of the heart, such as chronic heart failure, inflammatory diseases or inherited conditions. When medical therapy fails, the function of the right ventricle (RV) can be temporarily replaced by a mechanical device. Impella RP^® is a mechanical device, inserted into the heart without the need of a surgical operation, that bypasses the RV and ensures an adequate blood flow. Impella RP, while replaces the right ventricular function, allows time for the right ventricular recovery. When and if the RV recovers, Impella RP can be removed. As all the medical devices, Impella RP can be associated to adverse effects, mainly bleeding and damage of cardiac structures.
