Wall shear stress: the challenges of a rising imaging marker in current clinical practice

[摘要] Wall shear stress (WSS) is the tangential frictional force that occurs at the interface of flowing blood and the endothelial surface of a vessel. It impacts endothelial cell behavior with repercussions on the vascular smooth muscle cells and the entire vascular wall (1,2). Many pathophysiological phenomena are thought to be partly mediated by changes in WSS, such as the development of atherosclerotic plaques (3), aneurysmal growth (4,5), or the risk of dissection (6). Therefore, the identification of WSS in vivo, leveraging innovative imaging methods, is particularly exciting as it is a causal factor rather than a simple risk indicator.
