ABSTRACT
Right ventricular failure has a high morbidity and mortality in patients suffering from advanced heart failure, pulmonary hypertension, acute myocardial infarction after cardiac surgery and in left ventricular assist device patients. The Impella RP® catheter is a mechanical circulatory device, positioned from a venous femoral percutaneous access and passing through the tricuspid and pulmonary valves, reaches the pulmonary artery. Impella RP (Abiomed Inc., MA, USA) acts as a direct right ventricle bypass and it provides a flow up to 4.4 liters per minute, unloading the right ventricle. The main contraindications are thrombi in the vena cava, right atrium and ventricle and pulmonary artery; mechanical tricuspid or pulmonary prostheses. In this review, the principles of operations, clinical applications and results of Impella RP are summarized and evaluated.
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.
