Forecasting the occurrence of large, catastrophic slope failures remains very problematic. It is clear that in order advance this field a greater understanding is needed of the processes through which failure occurs. In particular, there is a need to comprehend the processes through which a rupture develops and propagates through the slope, and the nature of the inter-relationship between the s...
The majority of acute coronary syndromes occur without warning due to rupture of coronary atherosclerotic plaques. Coronary lesions prone to rupture reveal several high-risk features that can be identified before the development of devastating clinical events, using modern imaging modalities. Recent advances in coronary computed tomography angiography (CCTA) allow the identification, quantifica...
DESPITE THE INCREASED GLOBAL EXPERIENCE WITH TRANSCATHETER AORTIC VALVE REPLACEMENT (TAVR), there remain 3 major adverse events. Aortic rupture (Fig. 1), coronary artery obstruction (Fig. 2), and paravalvular leakage (PVL) (Fig. 3) may occur with valve implantation. Oversizing or excessive radial expansion force with the TAVR stent may cause aortic rupture, whereas insufficient dilation may lea...
Atherosclerosis is an inflammatory disorder that can evolve into an acute clinical event by plaque development, rupture, and thrombosis. Plaque vulnerability represents the susceptibility of a plaque to rupture and to result in an acute cardiovascular event. Nevertheless, plaque vulnerability is not an established medical diagnosis, but rather an evolving concept that has gained attention to im...
An assembly of two receptor ligand bonds in series will typically break at the weaker complex upon application of an external force. The rupture site depends highly on the binding potentials of both bonds and on the loading rate of the applied force. A model is presented that allows simulations of force-induced rupture of bonds in series at a given force and loading rate based on the natural di...
