Survey of Anticoagulation Practices with the Impella Percutaneous Ventricular Assist Device at High-Volume Centers

Figure 2

Summary of Impella Anticoagulation Practices. No consensus emerged with regard to any of the practices queried in the survey. A slight majority of centers used the default concentration of UFH recommended by the manufacturer and adjusted the initial IV UFH rate for purge flow. Many of the above practices diverge from the manufacturers’ recommendations. Abbreviations: ACT: activated clotting time, IV: intravenous, and UFH: unfractionated heparin.
