Strain in commercial grade bovine pericardium leaflets under diastolic pressure of 120 mmHg, as a function of collagen fibre patterns. Material properties calibrated from uniaxial and fatigue bulge loading.

Non-destructive optical analysis of commercial-grade bovine pericardium using in-house small angle light scattering (SALS). Contour plot shows heterogenous collagen fibre structure across patch, with alignment ranging from low to high (0.5 – 0.9).
