Abstract

The Impella 5.0 is a catheter-mounted left ventricular assist device that is inserted through the patient's subclavian artery. This device allows patient mobilization. Early mobility improves outcomes, including physical function and exercise tolerance, in critically ill patients and those with heart failure (HF). However, there have been no studies regarding the safety of early mobilization during the period of Impella 5.0 insertion based on hemodynamic assessment.

A 39-year-old man with idiopathic dilated cardiomyopathy and cardiogenic shock was transferred to our hospital for Impella 5.0 insertion. We started neuromuscular electrical stimulation (NMES) and mobilization eight days after Impella 5.0 insertion. The safety of NMES and mobilization was assessed based on mean blood pressure, heart rate (HR), and mean pulmonary artery pressure measurements as hemodynamic indicators. Muscle strength was also assessed using the Medical Research Council (MRC) scale. Throughout the interventions, only the HR increased slightly during mobilization, and there were no hemodynamic abnormalities. Also, the MRC scale score improved as mobilization progressed. The results presented here suggest that NMES and mobilization are safe and feasible in patients with Impella 5.0 insertion, and therefore should be widely adopted.
