The development of phantoms, mock replicas of anatomical structures, has allowed cardiovascular research to improve stent grafts and various methods of insertion and deployment. Stent-graft deployment often occurs in aneurysms, large dilatations of the aorta, where calcification of the arterial wall may affect the treatment’s efficiency. The experiment assessment of a mock calcified abdominal aortic aneurysm allows the evaluation of the impact of calcification on the arterial wall and the aneurysm. Using polyvinyl alcohol (PVA) hydrogel, the mechanical properties of the artery and the aneurysm can be replicated correctly; the addition of PVA/CaCO₃-based calcifications can then allow an examination of their impact on surrounding mock tissue through a series of tests on the phantoms: uniaxial tensile testing of mock arterial tissue with various degrees of calcification, finite element analysis of calcified tissue, and ultrasound imaging of calcified abdominal aortic aneurysm phantoms. At 15% strain, heavily calcified samples showed a significant load bearing effect, reducing wall stress up to 49% when compared to their non-calcified counterparts; this effect has, however, a small area of effect which can be clearly seen in smaller samples, while larger arterial phantoms could only demonstrate the effect locally in calcified areas.
