Isotropic linear and nonlinear fractional derivative constitutive relations are formulated and examined in terms of many parameter generalized Kelvin models and are analytically extended to cover general anisotropic homogeneous or non-homogeneous as well as functionally graded viscoelastic material behavior. Equivalent integral constitutive relations, which are computationally more powerful, ar...
Pressure wire-based fractional flow reserve is considered the standard of reference for evaluation of the ischemic potential of coronary stenoses and the expected benefit from revascularization. Accordingly, its application in daily practice or for research purposes has to be as standardized as possible to avoid technical or operator-related artifacts in pressure recordings. This document propo...
Longitudinal stent deformation (LSD) is a rare complication but can occur during coronary intervention. We report a case with LSD of the distal edge, documented by an optical coherence tomography investigation and successfully recovered.
In this issue of JACC: Cardiovascular Interventions, Tu et al. (1) report on an initial validation study for a less-invasive approach to derive fractional flow reserve (FFR) based on the coronary angiogram. The investigators should be congratulated on developing an innovative means to expand the diagnostic value of angiography by including physiological ischemic assessment, potentially broadeni...
