Abstract

Aims: Venous congestion is an important determinant of organ dysfunction in patients with pulmonary hypertension. Currently, there are no optimal methods for non-invasive assessment of venous congestion. We aimed to evaluate the accuracy of the recently described venous excess ultrasound grading system (VExUS) to determine the presence of venous congestion in patients with precapillary pulmonary hypertension compared to right heart catheterization.

Methods: We included patients with precapillary pulmonary hypertension undergoing right heart catheterization. VExUS was performed by trained cardiologists simultaneous with catheterization. Correlation and simple logistic regression between invasive hemodynamic measurement and VExUS was performed.

Results: Forty-nine patients with precapillary pulmonary hypertension were included. A significant correlation between VExUS and right atrial pressure (RAP) was found (R = 0.70, p < 0.001). VExUS was an excellent predictor of RAP > 10 mmHg (AUC 0.93, p < 0.001).

Conclusion: Our study provides evidence that VExUS score is a reliable, non-invasive method for assessing right atrial pressure in patients with pre-capillary PH.

静脉超声和右心导管在毛细血管前肺动脉高压中的应用。

目的：静脉充血是肺动脉高压患者器官功能障碍的重要决定因素。目前，尚无最佳的无创静脉充血评估方法。我们的目的是评估最近描述的静脉过量超声分级系统（VExUS）的准确性，以确定与右心导管插管相比，毛细血管前肺动脉高压患者是否存在静脉充血。方法：我们纳入了接受右心导管插管的毛细血管前肺动脉高压患者。VExUS由训练有素的心脏病专家在导管置入的同时进行。对有创血流动力学测量与VExUS进行相关性分析和简单逻辑回归分析。结果：纳入49例毛细血管前肺动脉高压患者。研究发现，VExUS评分与右房压（RAP）有显著相关性（R = 0.70, p = 10 mmHg (AUC 0.93, p)）。结论：我们的研究证明了VExUS评分是一种可靠的、无创的评估毛细血管前PH患者右房压的方法。
