Artery segment models of stent deformations—controlled deformations induce stress concentrations in regions that correlate with intra-device fracture location in patients. oRCA (ostial right coronary artery—top) represents a case of unilaterally constrained deformation that leads to severe focal deformation that is clinically suggestive of proximal fractures in the RCA, and mpLAD (mid-proximal left anterior descending—bottom) is the case of uniform end deformations that result in stress concentrations and deformation in the mid stent representative of what is observed in the LAD coronary artery in patients. The symbols denote regions of highest von Mises stress (inset) and match clinical reports of location of stent fracture.
