## Abstract The tearing of the valve leaflet of a cardiac bioprosthesis can cause early failure of this device, which is employed to replace a diseased native valve. This report involves the study of the behavior of 312 tissue samples (152 of calf pericardium and 160 of ostrich pericardium) treated
## Abstract The mechanical behavior of sutured ostrich pericardium was studied by uniaxial tensile testing. One hundred forty‐four tissue specimens were assessed: 96 sutured samples (48 in which a centrally located suture was placed at an angle of 90 degrees with respect to the longitudinal axis, w
In the fabrication of a bioprosthetic heart valve from bovine pa'cardial tissues, the tissues are subjected to suturing. The stress-strain response of sutured as well as unsutured strips of this tissue were examined. The stress-strain response was o!etermined using a tensile-testing machine. It was
