Point-of-Care Ultrasound in the Evaluation of Patients with Left Ventricular Assist Devices at the Emergency Department.

Background: Left ventricular assist devices (LVADs) can be used as a bridging therapy for myocardial recovery or cardiac transplant, as well as a destination therapy for long-term support in patients with advanced heart failure. Patients with LVADs can present to the emergency department (ED) for acute deterioration and emergency physicians (EPs) must be equipped with the necessary knowledge and skill to treat this unique population.

Objective: This review describes the role of point-of-care ultrasound (POCUS) in the evaluation of patients with LVADs and illustrates how EPs can incorporate POCUS into the evaluation of these patients in the ED.

Discussion: The clinical applications for which POCUS may be useful in patients with LVADs include hypotension or shock, dyspnea, cardiac failure, dysrhythmia, syncope, and cardiac arrest. The normal features of POCUS in patients with LVADs and the features of POCUS associated with diseased states are presented.

Conclusions: Patients with LVADs have altered anatomy and physiology. Therefore, an understanding of key modifications to standard POCUS views is necessary so that EPs can use POCUS effectively in their evaluation of these patients.
