Comparison of subclavian vein to inferior vena cava collapsibility by ultrasound in acute heart failure: A pilot study

Background Management of acute decompensated heart failure (ADHF) requires accurate assessment of relative intravascular volume, which may be technically challenging. Inferior vena cava (IVC) collapsibility with respiration reflects intravascular volume and right atrial pressure (RAP). Subclavian ve...

Description
Summary:Background Management of acute decompensated heart failure (ADHF) requires accurate assessment of relative intravascular volume, which may be technically challenging. Inferior vena cava (IVC) collapsibility with respiration reflects intravascular volume and right atrial pressure (RAP). Subclavian vein (SCV) collapsibility may provide an alternative. Hypothesis The purpose of this study was to examine the relationship between SCV collapsibility index (CI) and IVC CI in ADHF. Methods This was a prospective study of non‐ventilated patients with ADHF who had paired IVC and SCV ultrasound assessments. As SCV CI is highly position‐dependent, measurements were performed supine at 30–45°. Results Thirty‐three patients were included with 36 encounters. The sample size was adequately powered for receiver‐operator characteristic (ROC) analysis. SCV CI correlated with IVC CI during relaxed breathing (R = .65, n = 36, p
