摘要

In this study, we investigated the mechanical properties of porcine aortic sinus using a three-dimensional marker measuring technique called the direct linear transformation (DLT) method. By recording pressure-inflation tests of five porcine aortic roots with the use of two cameras simultaneously, we were able to obtain stress and strain responses of aortic sinus upon applied luminal pressures and compare them with previously published planar biaxial results of the same tissue. We found that the roots were stiffer in the circumferential direction for the middle region of the non-coronary sinus for all specimens. The magnitude of stress at 30% strain was higher than that observed using planar biaxial testing.
