Mechanical properties of adult and neonatal glutaraldehyde fixed bovine pericardium.

Test	Adult ()^†	Neonatal ()^†
Small strain (<0.2) elastic modulus (MPa)	4.8 (2.0)	71.9 (11.6)	<0.0001
Large strain (>0.2) elastic modulus (MPa)	33.5 (3.2)	83.7 (10.6)	<0.0001
Ultimate tensile strength (MPa)	19.1 (2.2)	32.9 (4.1)	0.0050
Strain at failure	0.80 (0.06)	0.48 (0.03)	0.0002
