Abstract

Intracoronary stenting (PCI) has become standard revascularization technique to reopen blocked arteries. Although significant progress in stenting technology and implantation techniques has been made a number of problems remain. Specifically, stent sizing and inflation pressures are still a matter of scientific debates. Despite a large number of biomechanical computational simulations experimental data are rare, likely due to technical difficulties to measure dilatation pressures and coronary dimensions in the same settings. Our study shows that valuable data can be obtained by employing digital image correlation for 3D strain measurement during stent inflation ex-vivo that can provide further insight into the stent–artery wall interactions.
