Ventricular Assist Device Use in Patients With Single-Ventricle Circulation.

Ventricular assist devices (VADs) are being increasingly used to support patients with congenital heart disease and single-ventricle physiology. Because of their unique anatomy and physiology, special consideration must be used to provide effective mechanical circulatory support for each individual patient. This can include alternative cannulation techniques, strategies to balance cardiac output to the systemic and pulmonary circulations from a single ventricle, or the use of continuous vs pulsatile VADs for better ventricular offloading. In this article we review the etiology of single-ventricle failure, VAD options for support, cannulation strategies, post-VAD management considerations, and outcomes at each of the 3 stages of palliation.
