Uniaxial tensile mechanical properties of PV leaflets. (A) Preparation and cutting direction of PV leaflets. PV leaflets were cut out in the radial or circumferential direction (F fibrosa, S spongiosa, V ventricularis); (B) representative uniaxial tensile stress–strain curves for young and adult PV leaflets in circumferential and radial directions; summarized elastic modulus (C), ultimate stress (D), and ultimate strain (E) (5 PV leaflets from three pigs for each age group, bars that do not share letters are significantly different from each other).
