Ultrasound (US)-based measurements of the inferior vena cava (IVC) diameter are widely used to estimate right atrial pressure (RAP) in a variety of clinical settings. However, the correlation with invasively measured RAP along with the reproducibility of US-based IVC measurements is modest at best. In the present manuscript, we discuss the limitations of the current technique to estimate RAP through IVC US assessment and present a new promising tool developed by our research group, the automated IVC edge-to-edge tracking system, which has the potential to improve RAP assessment by transforming the current categorical classification (low, normal, high RAP) in a continuous and precise RAP estimation technique. Finally, we critically evaluate all the clinical settings in which this new tool could improve current practice.
基于超声（US）测量下腔静脉（IVC）直径在各种临床环境中被广泛用于估计右心房压力（RAP）。然而，与通过侵入性测量获得的RAP之间的相关性以及基于US的IVC测量的可重复性充其量只是中等程度。在本手稿中，我们讨论了通过IVC US评估来估计RAP的当前技术的局限性，并介绍了我们研究小组开发的一种新的有前景的工具——自动IVC边缘到边缘跟踪系统，该系统有可能通过将当前的分类（低、正常、高RAP）转变为一种连续且精确的RAP估计技术来改善RAP评估。最后，我们严格评估了这种新工具能够改进当前实践的所有临床环境。
