We have previously proposed dynamic fixation as an alternative method to fix a porcine aortic heart valve xenograft with better tissue fixation and better preservation of its natural biomechanical properties. Bovine pericardium was fixed under dynamic conditions, low pressures (< 4 mmHg) and low vibration rate (1.2 Hz) in a 0.5% glutaraldehyde phosphate buffer (pH 7.4, 0.2 M). After fixation, tensile testing (i.e. relaxation and stress-strain curves) was performed at low and high extension… CONTINUE READING
