Validating the Venous Excess Ultrasound Score (VExUS) for Right Atrial Pressure Assessment in Pulmonary Hypertension: A Multicenter Study

MedXY Editorial Team•Sep 3, 2026•Cardiology

The Venous Excess Ultrasound Score (VExUS) demonstrates strong graded correlation with invasively measured right atrial pressure (RAP) in patients with pulmonary hypertension (PH).
VExUS shows excellent diagnostic accuracy (AUC 0.97) for detecting elevated RAP >12 mmHg, surpassing isolated echocardiographic markers and matching composite echocardiographic RAP estimation.
Accuracy of VExUS holds consistent across pre-capillary, post-capillary, and non-pulmonary hypertension hemodynamic profiles, emphasizing broad clinical applicability.
This noninvasive tool may enhance bedside assessment of systemic venous congestion, guiding management in PH and other conditions of elevated venous pressure.
