Usefulness of Serial Measurements of Inferior Vena Cava Diameter by Vscan to Identify Patients With Heart Failure at High Risk of Hospitalization.

Estimation of volume status is integral to heart failure (HF) management. Measurement of inferior vena cava (IVC) diameter (IVCd) by ultrasound provides a noninvasive estimate of right atrial pressures. The GE Vscan is a handheld ultrasound (HHU) device that allows for point-of-care measurements to assess volume status.
