Role of Internal Jugular Venous Ultrasound in suspected or confirmed Heart Failure: A Systematic Review

•Limited data are available on the use of internal jugular vein ultrasound parameters to assess central venous pressure and clinical outcomes among patients with suspected or confirmed heart failure.•We identified studies evaluating the accuracy and reliability of the internal jugular vein ultrasound parameters and explored its correlation with central venous pressure and clinical outcomes among adult patients with suspected or confirmed acutely decompensated heart failure.•Our systematic review included 11 studies with 1481 patients with presumed heart failure. We observed a significant role for ultrasound interrogation of the internal jugular vein in the evaluation of patients in the ED presenting with dyspnea, in the outpatient clinic for poor clinical outcomes in heart failure, and in determining the timing of discharge for patients admitted with acutely decompensated heart failure.
