Abstract
Purpose: Impella microaxial ventricular assist devices require a dextrose-based purge solution in combination with heparin or sodium bicarbonate to prevent device dysfunction and stoppage, but the dextrose in these solutions can interfere with positron emission tomography (PET) scans, necessitating an alternative approach.
Summary: We describe the short-term use in 2 cases of an alternative purge solution for patients with an Impella 5.5 ventricular assist device undergoing PET scans to rule out infection and malignancy. Sodium chloride solutions cannot be used with Impella ventricular assist devices even for short periods of time due to the potential for motor corrosion. We therefore selected a sterile water-based sodium bicarbonate purge solution, incorporating a short dextrose-free period before and during the PET scan. Imaging was successfully performed with this alternative solution, with monitoring of Impella performance levels and purge parameters throughout the procedure indicating no adverse effects on pump function.
Conclusion: Our sterile water-based bicarbonate purge solution coupled with a short-term restriction of dextrose is a practical option for PET imaging in patients with an Impella ventricular assist device.
